I. SUMMARY

Present law

Under the present-law Federal income tax system, U.S. persons are subject to U.S. income tax on all income, whether derived in the United States or abroad. However, the United States generally allows a credit against the U.S. tax imposed on income derived from foreign sources for foreign income taxes imposed on such income. Foreign persons are subject to U.S. tax only on income that has a sufficient connection to the United States.

Within this basic framework, there are a variety of rules that affect the U.S. taxation of international transactions. Detailed rules govern the determination of the source of income and the allocation and apportionment of expenses between foreign-source and U.S.-source income. Such rules are relevant not only for purposes of determining the U.S. taxation of foreign persons (because foreign persons are subject to U.S. tax only on income that is from U.S. sources or otherwise has sufficient U.S. nexus), but also for purposes of determining the U.S. taxation of U.S. persons (because the U.S. tax on a U.S. person's foreign-source income may be reduced or eliminated by foreign tax credits). Authority is provided for the reallocation of items of income and deduction between related persons in order to ensure the clear reflection of the income of each person and to prevent the evasion of tax. Although U.S. tax generally is not imposed on a foreign corporation that operates abroad, several anti-deferral regimes apply to impose current U.S. tax on certain income from foreign operations of a U.S.-owned foreign corporation.

An international transaction potentially gives rise to tax consequences in two (or more) countries. The tax treatment in each country generally is determined under the tax laws of the respective country. However, an income tax treaty between the two countries may operate to coordinate the two tax regimes and minimize the double taxation of the transaction. In this regard, the United States' network of bilateral income tax treaties includes provisions affecting both U.S. and foreign taxation of both U.S. persons with foreign income and foreign persons with U.S. income.

Trends in U.S. international trade and investment

Foreign trade has become increasingly important to the United States economy. Exports and imports each have risen from less than six percent of GDP in 1962 to more than 14 percent in 1997. The United States generally was a net exporter of goods and services prior to 1982. Since that time, the United States has been a net importer of goods and services.

Trade deficits, capital inflows, investment, savings, and income are all connected in the economy. The value of an economy's total output must be either consumed domestically (by private individuals and government), invested domestically, or exported abroad. If an economy consumes and invests more than it produces, it must be a net importer of goods and services. If the imports were all consumption goods, in order to pay for those imports, the country must either sell some of its assets or borrow from foreigners. If the imports were investment goods, foreign persons would own the investments. Thus, an economy that runs a trade deficit will also experience foreign capital inflows as foreign persons purchase domestic assets, make equity investments or lend funds (purchase debt instruments).

Net foreign investment has become a larger proportion of the economy and a more significant proportion of total domestic investment than in the past. In 1982, the United States changed from being a modest exporter of capital in relation to GDP to being a large importer of capital. In 1997, gross investment in the United States was $1,351 billion and net foreign investment was $141 billion, or 10.4 percent of gross domestic investment. The value of foreign assets owned by private U.S. persons has grown from $295.1 billion in 1980 to $3,477 billion in 1996. This growth in value has not been as rapid as the growth in the value of assets in the United States owned by foreign persons.

Economic issues in the taxation of international transactions

In general.--International investment plays an important role in determining the total amount of worldwide income as well as the distribution of income across nations. In addition, international investment flows can substantially influence the distribution of capital and labor income within nations. Because each government levies taxes by its own method and at its own rates, the resulting system of international taxation can distort investment and contribute to reductions in worldwide economic welfare.

The nature of these distortions depends on the method of taxing income from international investment. If investment income is taxed only at the source, substantial amounts of capital could be diverted to jurisdictions with the lowest tax rates instead of flowing to investment projects with the highest pre-tax rate of return. If a system of residence taxation is the worldwide norm, enterprises resident in low-tax countries might be able to attract more investment capital or perhaps increase their market share through lower prices to the detriment of enterprises resident in high-tax jurisdictions, even though the latter are more efficient. In either case, capital is diverted from its more productive uses, and worldwide income and efficiency suffer. The most straightforward solution to this problem is equalization of effective tax rates, but this may not be a practical solution given differences in national preferences for the amount and method of taxation. There is no consensus on what method of taxing international investment income minimizes distortions in the allocation of capital when nations tax income at different effective rates, but the alternatives of capital export neutrality and capital import neutrality are the most cited guiding principles. These two standards are each desirable goals of international tax policy. The problem is that, with unequal tax rates, these two goals are not mutually attainable.

Capital export neutrality.--Capital export neutrality refers to a system where an investor residing in a particular locality can locate investment anywhere in the world and pay the same tax. Under capital export neutrality, decisions on the location of investment are not distorted by taxes. Capital export neutrality is a principle describing how investors pay tax, not to whom they pay. Capital export neutrality primarily is a framework for discussing the efficiency and incentives faced by private investors, and not the distribution of the revenues and benefits of international investment.

Capital import neutrality.--Capital import neutrality refers to a system of international taxation where income from investment located in each country is taxed at the same rate regardless of the residence of the investor. Some commentators refer to the principle of capital import neutrality as promoting "competitiveness." Under capital import neutrality, capital income from all businesses operating in any one locality is subject to uniform taxation. The nationality of investors in a particular locality will not affect the rate of tax.

Although they have important implications for national welfare as well as the distribution of income between capital and labor, the debate on the relative merits of capital export neutrality and capital import neutrality centers on which of these more efficiently allocates capital around the world and therefore on which better promotes worldwide economic welfare.


II. PRESENT LAW

A. U.S. Taxation of U.S. Persons with Foreign Income

1. Overview

The United States taxes U.S. citizens, residents, and corporations (collectively, U.S. persons) on all income, whether derived in the United States or elsewhere. By contrast, the United States taxes nonresident alien individuals and foreign corporations only on income with a sufficient nexus to the United States.

The United States generally cedes the primary right to tax income derived from sources outside the United States to the foreign country where such income is derived. Thus, a credit against the U.S. income tax imposed on foreign-source taxable income is provided for foreign taxes paid on that income. In order to implement the rules for computing the foreign tax credit, the Code and the regulations thereunder set forth an extensive set of rules governing the determination of the source, either U.S. or foreign, of items of income and the allocation and apportionment of items of expense against such categories of income.

The tax rules of foreign countries that apply to foreign income of U.S. persons vary widely. For example, some foreign countries impose income tax at higher effective rates than the United States. In such cases, the foreign tax credit allowed by the United States is likely to eliminate any U.S. tax on income from a U.S. person's operations in the foreign country. On the other hand, operations in countries that have low statutory tax rates or generous deduction allowances or that offer tax incentives (e.g., tax holidays) to foreign investors are apt to be taxed at effective tax rates lower than the U.S. rates. In such cases, after application of the foreign tax credit, a residual U.S. tax generally is imposed on income from a U.S. person's operations in the foreign country.

Under income tax treaties, the tax that otherwise would be imposed under applicable foreign law on certain foreign-source income earned by U.S. persons may be reduced or eliminated. Moreover, U.S. tax on foreign-source income may be reduced or eliminated by treaty provisions that treat certain foreign taxes as creditable for purposes of computing U.S. tax liability.

2. Foreign operations conducted directly

The tax rules applicable to U.S. persons that control business operations in foreign countries depend on whether the business operations are conducted directly (through a foreign branch, for example) or indirectly (through a separate foreign corporation). A U.S. person that conducts foreign operations directly includes the income and losses from such operations on such person's U.S. tax return for the year the income is earned or the loss is incurred. Detailed rules are provided for the translation into U.S. currency of amounts with respect to such foreign operations. Thus, the income from the U.S. person's foreign operations is subject to current U.S. tax. However, a foreign tax credit may reduce or eliminate the U.S. tax on such income.

3. Foreign operations conducted through a foreign corporation

In general.--Income earned by a foreign corporation from its foreign operations generally is subject to U.S. tax only when such income is distributed to any U.S. persons that hold stock in such corporation. Accordingly, a U.S. person that conducts foreign operations through a foreign corporation generally is subject to U.S. tax on the income from those operations when the income is repatriated to the United States through a dividend distribution to the U.S. person. The income is reported on the U.S. person's tax return for the year the distribution is received, and the United States imposes tax on such income at that time. A foreign tax credit may reduce the U.S. tax imposed on such income.

A variety of complex anti-deferral regimes impose current U.S. tax on income earned by a U.S. person through a foreign corporation. The main anti-deferral regimes set forth in the Code (in order of enactment) are the foreign personal holding company rules (secs. 551-558), the controlled foreign corporation rules of subpart F (secs. 951-964), and the passive foreign investment company rules (secs. 1291-1298). Additional anti-deferral regimes set forth in the Code are the personal holding company rules (secs. 541-547), the accumulated earnings tax (secs. 531-537), and the foreign investment company and electing foreign investment company rules (secs. 1246 and 1247).

Foreign personal holding companies.--The Revenue Act of 1937 established an anti-deferral regime for foreign personal holding companies ("FPHCs"). A FPHC generally is defined as any foreign corporation if five or fewer U.S. individual citizens or residents own (directly, indirectly, or constructively) more than 50 percent of the corporation's stock (measured by vote or value), and at least 60 percent of the corporation's gross income consists of certain types of passive income (such as dividends, interest, certain royalties and certain rents).(2) If a foreign corporation is a FPHC, all the U.S. shareholders of the corporation are subject to U.S. tax currently on their pro rata share of the corporation's undistributed foreign personal holding company income.

Controlled foreign corporations.--The Revenue Act of 1962 established an anti-deferral regime for controlled foreign corporations ("CFCs") under subpart F of the Code. A CFC generally is defined as any foreign corporation if U.S. persons own (directly, indirectly, or constructively) more than 50 percent of the corporation's stock (measured by vote or value), taking into account only those U.S. persons that own at least 10 percent of the stock (measured by vote only). Under the subpart F rules, the United States generally taxes the U.S. 10-percent shareholders of a CFC on their pro rata shares of certain income of the CFC (referred to as "subpart F income"), without regard to whether the income is distributed to the shareholders. Subpart F income typically is passive income or income that is relatively movable from one taxing jurisdiction to another. Subpart F income consists of foreign base company income (defined in sec. 954), insurance income (defined in sec. 953), and certain income relating to international boycotts and other violations of public policy (defined in sec. 952(a)(3)-(5)). Foreign base company income, in turn, includes foreign personal holding company income, foreign base company sales income, foreign base company services income, foreign base company shipping income and foreign base company oil-related income. For example, foreign personal holding company income includes, among other items, dividends, interest, rents and royalties (subject to certain exceptions). In effect, the United States treats the U.S. 10-percent shareholders of a CFC as having received a current distribution out of the CFC's subpart F income. In addition, the U.S. 10-percent shareholders of a CFC are required to include currently in income for U.S. tax purposes their pro rata shares of the CFC's earnings invested in U.S. property. The U.S. tax on such amounts may be reduced through foreign tax credits.

Passive foreign investment companies.--The Tax Reform Act of 1986 established an anti-deferral regime for passive foreign investment companies ("PFICs"). A PFIC generally is defined as any foreign corporation if 75 percent or more of its gross income for the taxable year consists of passive income, or 50 percent or more of its assets consists of assets that produce, or are held for the production of, passive income.(3) Alternative sets of income inclusion rules apply to U.S. persons that are shareholders in a PFIC, regardless of their percentage ownership in the PFIC. One set of rules applies to PFICs that are "qualified electing funds," under which electing U.S. shareholders currently include in gross income their respective shares of the PFIC's earnings, with a separate election to defer payment of tax, subject to an interest charge, on income not currently received. A second set of rules applies to PFICs that are not qualified electing funds, under which U.S. shareholders pay tax on certain income or gain realized through the PFIC, plus an interest charge that is attributable to the value of deferral. A third set of rules applies to PFIC stock that is marketable, under which electing U.S. shareholders currently take into account as income (or loss) the difference between the fair market value of their PFIC stock as of the close of the taxable year over their adjusted basis in such stock (subject to certain limitations).

Detailed rules for coordination among the anti-deferral regimes are provided to prevent U.S. persons from being subject to U.S. tax on the same item of income under multiple regimes. For example, the PFIC rules generally do not apply to U.S. shareholders that are subject to the subpart F rules.

4. Transfer pricing rules

In the case of a multinational enterprise that includes at least one U.S. corporation and at least one foreign corporation, the United States taxes all of the income of the U.S. corporation, but only so much of the income of the foreign corporation as is determined to have sufficient nexus to the United States. The determination of the amount that properly is the income of the U.S. member of a multinational enterprise and the amount that properly is the income of a foreign member of the same multinational enterprise thus is critical to determining the amount of income the United States may tax (as well as the amount of income other countries may tax).

Due to the variance in tax rates and tax systems among countries, a multinational enterprise may have a strong incentive to shift income, deductions, or tax credits among commonly controlled entities in order to arrive at a reduced overall tax burden. Such a shifting of items between commonly controlled entities could be accomplished by establishing artificial transfer prices for transactions between group members.

Under section 482, the Secretary of the Treasury is authorized to redetermine the income of an entity subject to U.S. taxation, when it appears that an improper shifting of income between that entity and a commonly controlled entity has occurred. This authority is not limited to reallocations of income between different countries; it permits reallocations in any common control situation, including reallocations between two U.S. entities. However, it has significant application to multinational enterprises due to the incentives for taxpayers to shift income to obtain the benefits of significantly different effective tax rates.

Section 482 grants the Secretary of the Treasury broad authority to allocate income, deductions, credits or allowances between any commonly controlled organizations, trades, or businesses in order to prevent evasion of taxes or to clearly reflect income. The statute generally does not prescribe any specific reallocation rules that must be followed, other than establishing the general standards of preventing tax evasion and clearly reflecting income. Treasury regulations adopt the concept of an arm's-length standard as the method for determining whether reallocations are appropriate. Thus, the regulations attempt to identify the respective amounts of taxable income of the related parties that would have resulted if the parties had been uncontrolled parties dealing at arm's length. The regulations contain extremely complex rules governing the determination of an arm's-length charge for various types of transactions. The regulations generally attempt to prescribe methods for identifying a relevant comparable unrelated party transaction and for providing adjustments for differences between such transactions and the related party transactions in question. In some instances, the regulations also provide safe harbors.

Determinations under section 482 that result in the allocation of additional income to the United States theoretically might subject a taxpayer to double taxation if, for example, both the United States and another country imposed tax on the same income and the other country did not agree that the income should be reallocated to the United States. Tax treaties generally provide mechanisms that attempt to resolve such disputes in a manner that may avoid double taxation if both countries agree. Such mechanisms include the designation of a "competent authority" by each country to act as that country's representative in the negotiation attempting to resolve such disputes. Such competent authority procedures, however, do not guarantee that double tax will not be imposed in a particular case.

One method for addressing the issue of double taxation is through the recently-developed advance pricing agreement ("APA") procedures. An APA is an advance agreement establishing an approved transfer pricing methodology entered into between the taxpayer, the Internal Revenue Service ("IRS"), and a foreign tax authority. The taxpayer generally is required to use the approved transfer pricing methodology for the duration of the APA. The IRS and the foreign tax authority generally agree to accept the results of such approved methodology. An APA also may be negotiated between only the taxpayer and the IRS; such an APA establishes an approved transfer pricing methodology for U.S. tax purposes. The APA process may prove to be particularly useful in cases involving industries such as financial products and services for which transfer pricing determinations are especially difficult.(4)

5. Foreign tax credit rules

Because the United States taxes U.S. persons on their worldwide income, Congress enacted the foreign tax credit in 1918 to prevent U.S. taxpayers from being taxed twice on their foreign-source income: once by the foreign country where the income is earned and again by the United States. The foreign tax credit generally allows U.S. taxpayers to reduce the U.S. income tax on their foreign-source income by the foreign income taxes they pay on that income. The foreign tax credit, however, does not operate to offset U.S. income tax on U.S.-source income.

A credit against U.S. tax on foreign-source income is allowed for foreign taxes directly paid or accrued by a U.S. person (the "direct" foreign tax credit). In addition, a credit is allowed to a U.S. corporation for foreign taxes paid by certain foreign subsidiary corporations and deemed paid by the U.S. corporation upon a dividend received by, or certain other income inclusions of, the U.S. corporation with respect to earnings of the foreign subsidiary (the "deemed-paid" or "indirect" foreign tax credit).

The foreign tax credit provisions are elective on a year-by-year basis. In lieu of electing the foreign tax credit, U.S. persons generally are permitted to deduct foreign taxes. For purposes of the alternative minimum tax, foreign tax credit s generally cannot be used to offset more than 90 percent of the U.S. person's pre-foreign tax credit tentative minimum tax.

A foreign tax credit limitation, which is calculated separately for various categories of income, is imposed to prevent the use of foreign tax credits to offset U.S. tax on U.S.-source income. Under this limitation, the credit for foreign taxes on income in a particular category may not exceed the same proportion of the taxpayer's U.S. tax liability which the taxpayer's foreign-source taxable income in that category bears to the taxpayer's worldwide taxable income for the taxable year. Detailed rules are provided for the allocation of expenses against foreign-source income. Special rules apply to require the recharacterization of foreign-source income for a year subsequent to a foreign loss year as U.S.-source income.

The amount of creditable taxes paid or accrued (or deemed paid) in any taxable year which exceeds the foreign tax credit limitation is permitted to be carried back to the two immediately preceding taxable years and carried forward to the first five succeeding taxable years, and credited in such years to the extent that the taxpayer otherwise has excess foreign tax credit limitation for those years. For purposes of determining excess foreign tax credit limitation amounts, the foreign tax credit separate limitation rules apply.

6. Foreign sales corporations

A foreign sales corporation ("FSC") typically is owned by a U.S. corporation that produces goods in the United States. The U.S. corporation either supplies goods to the FSC for resale abroad to unrelated persons or pays the FSC a commission in connection with its sales to unrelated persons. Under special tax provisions, a portion of the export income of an eligible FSC is exempt from U.S. income tax (secs. 921-927). In addition, a U.S. corporation is not subject to U.S. tax on dividends distributed from the FSC out of earnings attributable to certain export income. Thus, there generally is no corporate level tax imposed on a portion of the income from exports of a FSC.(5)

B. U.S. Taxation of Foreign Persons with U.S. Income

1. Overview

The United States imposes tax on nonresident alien individuals and foreign corporations (collectively, foreign persons) only on income that has a sufficient nexus to the United States. In contrast, the United States imposes tax on U.S. persons on all income, whether derived in the United States or in a foreign country.

Foreign persons are subject to U.S. tax on income that is "effectively connected" with the conduct of a trade or business in the United States, without regard to whether such income is derived from U.S. sources or foreign sources. Such income generally is taxed in the same manner and at the same rates as income of a U.S. person. An applicable tax treaty may limit the imposition of U.S. tax on business operations of a foreign person to cases where the business is conducted through a permanent establishment in the United States.

In addition, foreign persons generally are subject to U.S. tax at a 30-percent rate on certain gross income derived from U.S. sources. Pursuant to an applicable tax treaty, the 30-percent gross-basis tax imposed on foreign persons may be reduced or eliminated.

The source of income for U.S. tax purposes is determined based on various factors, including the location or nationality of the payor, the location or nationality of the recipient, the location of the activities that generate the income, and the location of the assets that generate the income. For example, income from the sale or exchange of inventory property that is produced (in whole or in part) within the United States and sold or exchanged outside the United States, or produced (in whole or in part) outside the United States and sold or exchanged within the United States, is treated as partly from U.S. sources and partly from foreign sources. In general, 50 percent of such income is treated as attributable to production activities and is sourced based on the location of the production assets; the other 50 percent of such income is treated as attributable to sales activities and generally is sourced where the sale occurs.

2. Net-basis taxation

The United States taxes on a net basis and at the generally applicable U.S. tax rates the income of foreign persons that is "effectively connected" with the conduct of a trade or business in the United States. Any gross income earned by the foreign person that is not effectively connected with the person's U.S. business is not taken into account in determining the rates of U.S. tax applicable to the person's income from such business.

The determination of whether a foreign person is engaged in a U.S. trade or business is based on the facts and circumstances. Basic issues involved in the determination include whether the activity constitutes business rather than investing, whether sufficient activities in connection with the business are conducted in the United States, and whether the relationship between the foreign person and persons performing functions in the United States with respect to the business is sufficient to attribute those functions to the foreign person.

The factors taken into account in determining whether income, gain or loss is effectively connected with a U.S. trade or business include, for example, in the case of U.S.-source capital gains and certain U.S.-source passive income, whether the amount is derived from assets used or held for use in the conduct of the U.S. trade or business and whether the activities of the trade or business were a material factor in the realization of such amount. In the case of any other U.S.-source income, gain, or loss, such amounts are all treated as effectively connected with the conduct of the trade or business in the United States. Only specific types of foreign-source income are considered to be effectively connected with a U.S. trade or business (sec. 864(c)(4)). Foreign-source income of a type not specified generally is exempt from U.S. tax.

3. Gross-basis taxation

In the case of U.S.-source interest, dividends, rents, royalties, or other similar types of income (known as fixed or determinable, annual or periodical gains, profits and income), the United States generally imposes a flat 30-percent tax on the gross amount paid to a foreign person if such income or gain is not effectively connected with the conduct of a U.S. trade or business. This tax generally is collected by means of withholding by the person making the payment to the foreign person receiving the income. Accordingly, the 30-percent gross-basis tax is generally referred to as a withholding tax. In most instances, the amount withheld by the U.S. payor is the final tax liability of the foreign recipient and, thus, the foreign recipient files no U.S. tax return with respect to this income.

Certain exclusions or exceptions from the withholding tax apply. For example, the United States generally does not tax capital gains of a foreign corporation that are not connected with a U.S. trade or business. Capital gains of a nonresident alien individual that are not connected with a U.S. business generally are subject to the 30-percent gross-basis tax only if the individual was present in the United States for 183 days or more during the year (sec. 871(a)(2)). In addition, certain types of interest (for example, interest from certain bank deposits and from certain portfolio obligations) are not subject to the withholding tax.

C. Income Tax Treaties

In addition to the U.S. and foreign statutory rules for the taxation of foreign income of U.S. persons and U.S. income of foreign persons, bilateral income tax treaties limit the amount of income tax that may be imposed by one treaty partner on residents of the other treaty partner. For example, treaties often reduce or exempt withholding taxes imposed by a treaty country on certain types of income (e.g., dividends, interest and royalties) paid to residents of the other treaty country. Treaties also contain provisions governing the creditability of taxes imposed by the treaty country in which income was earned in computing the amount of tax owed to the other country by its residents with respect to such income. Treaties further provide procedures under which inconsistent positions taken by the treaty countries with respect to a single item of income or deduction may be mutually resolved by the two countries.

III. BACKGROUND AND DATA RELATING TO INTERNATIONAL TRADE AND INVESTMENT

This part presents background data relating to the scope of the international trade sector in the United States economy. This part discusses the economic relationship between trade deficits, capital inflows, investment, and savings in the economy. It briefly reviews trends in both the current account (the trade surplus or deficit) and the capital account (U.S. investment abroad and foreign investment in the United States).

A. Trade Deficits and Cross Border Capital Flows

National income accounting

In popular discussion of trade issues, much attention is given to the trade deficit or surplus, that is, the difference between the exports and imports of the economy. In the late 1980s, there was also attention given to inflows of capital from abroad. Capital inflows can take the form of foreign purchases of domestic physical assets, of equity interests, or of debt instruments. These two phenomena, trade balances and capital inflows, are not independent, but are related to each other. Trade deficits, capital inflows, investment, savings, and income are all connected in the economy. The connection among these economic variables can be examined through the national income and product accounts, which measure the flow of goods and services and income in the economy.(6)

The value of an economy's total output must be either consumed domestically (by private individuals and government), invested domestically, or exported abroad. If an economy consumes and invests more than it produces, it must be a net importer of goods and services. If the imports were all consumption goods, in order to pay for those imports, the country must either sell some of its assets or borrow from foreigners. If the imports were investment goods, foreign persons would own the investments. Thus, an economy that runs a trade deficit will also experience foreign capital inflows as foreign persons purchase domestic assets, make equity investments or lend funds (purchase debt instruments).

For example, when the United States imports more than it exports, the United States pays for the imports with dollars. If foreigners are not buying goods with the dollars, then they will use the dollars to purchase U.S. assets. (An alternate way of viewing these relationships is that dollars flowing out of the U.S. economy in order to purchase goods or to service foreign debt must ultimately return to the economy as payment for exports or as capital inflows.)

The previous discussion focuses on the disposition of the economy's output. If the economy is a net importer, it must attract capital inflows to pay for those imports. If the economy is a net exporter, it must have capital outflows to dispose of the payments it receives for its exports. Another way of looking at the connection between capital flows and the goods and services in the economy is to concentrate on the sources of funds for investment. Because domestic investment must be financed either through saving or foreign borrowing, net capital inflows must also equal the difference between domestic investment and saving.

These relationships can be summarized as follows (the equation ignores relatively small unilateral transfers such as foreign aid and assumes, without loss of generality, that the government budget is balanced):

Net Foreign Borrowing = Investment - Saving,

= (Imports - Exports) - Net Investment Income

For this purpose, imports and exports include both goods and services, and net investment income is equal to the excess of investment income received from abroad over investment income sent abroad.(7) The excess of imports over exports is called the trade deficit in goods and services. Net investment income can be viewed as payments received on previously-acquired foreign assets (foreign investments) less payments made to service foreign debt.

If the investment in an economy is larger than that country's saving, the country must either be running a trade deficit or the economy is increasing its foreign borrowing. Similarly, a country cannot run a trade surplus without also exporting capital, either by increasing its foreign investments, or by servicing previously-acquired foreign debt. Because the level of net investment income in any year is fixed by the level of previous foreign investment (except for changes in interest rates), changes in investment or saving that are associated with capital inflows will have a negative impact on a country's trade balance.

Economic implications of trade deficits

A trade deficit is not necessarily undesirable. What is important is the present and future consumption possibilities of the economy. That will depend in part on whether the trade deficit is financing consumption or investment. For example, if a country uncovers profitable investment opportunities, then it will be in that country's interest to obtain funds from abroad to invest in these profitable projects.(8) If the economy currently does not have enough domestic savings to invest in these projects, it could reduce its consumption (generating more domestic saving) or look to foreign sources of funds (thus allowing investment without reducing current consumption). For example, suppose new oil reserves that could be profitably recovered through increased investment are discovered in the United States. The investment may be financed by foreigners. In order to invest in U.S. assets, foreigners will have to buy dollars, thus increasing the value of the dollar. This dollar appreciation makes U.S. goods more expensive to foreigners, thereby reducing their demand for U.S. exports. At the same time, the dollar appreciation makes foreign goods cheaper for U.S. residents, increasing the demand for imports and resulting in a trade deficit. Eventually, the flow of capital will be reversed, as the U.S. demand for new investment falls, and foreigners receive interest and dividend payments on their previous investments.

The foreign borrowing in the above example was used to finance investment. This borrowing did not reduce the living standards of current or future U.S. residents, because the interest and dividends that were paid to foreigners came from the return from the new investment. If foreign borrowing finances consumption instead of investment, there are no new assets created to generate a return that can support the borrowing. When the debt eventually is repaid, the repayments will come at the expense of future consumption. For instance, consider a situation in which the domestic supply of funds for investment decreases because domestic saving rates fall. Foreign borrowing in this case is not associated with increased investment, but instead is devoted to investment that was previously financed with domestic savings. Because the foreign borrowing is not associated with increased investment, future output does not increase, and interest and dividends on the investment will be paid to foreign persons at the expense of future domestic consumption. In this case, there may be an increase in the standard of living for current U.S. residents at the expense of a decrease in the standard of living of future residents.

During the period that foreign borrowing finances U.S. consumption, the United States runs a trade deficit. Although the United States could service its growing foreign debt by increased borrowing, and hence larger trade deficits, in the long run trade deficits cannot keep growing. In fact, the United States must eventually run a trade surplus. If the United States imported more goods than it exported every year, there also would be an inflow of foreign capital every year. This capital inflow would be growing with the increasing costs of servicing the foreign debt. Eventually, foreigners would be unwilling to continue lending to the United States, and the value of the dollar would fall. The fall in the dollar would eliminate the trade deficit, and the United States would eventually run a trade surplus, so that the current account deficit (the sum of the trade deficit in goods and services and the net interest on foreign obligations) would be small enough for foreigners to be willing to lend again to the United States.

Even when foreign investment finances domestic consumption, trade deficits and capital inflows themselves should not necessarily be viewed as undesirable, because the foreign capital inflows help to keep domestic investment, and hence labor productivity, from falling. For instance, the large inflow of foreign capital to the United States in the 1980s is widely viewed to be a result of low U.S. saving rates. If the mobility of foreign capital had been restricted (through capital or import controls, for example), then the low saving rate could have led to higher domestic interest rates and lower rates of investment. That decreased investment would have led to decreases in future living standards because the lower growth rate of the capital stock would have resulted in lower growth rates of U.S. labor productivity. The fact that foreign capital was not restricted and did finance U.S. investment helped mitigate the negative effects on economic growth of low domestic saving.

The above observations support the argument that the trade deficit does not in itself provide a useful measure of international competitiveness, since trade deficits and trade surpluses can be either good or bad for the United States. The example of oil discovery discussed above shows that even increases in a country's stock of exportable goods can have ambiguous effects on the trade deficit. If the discovery of oil also increases the demand for investment, then the trade deficit may actually increase in the short run. Increases in natural resources, advances in technology, increases in worker efficiency, and other wealth-enhancing innovations have ambiguous effects on the trade deficit in the short and medium run. Because these innovations increase the productivity of U.S. workers and lower production costs, they increase the attractiveness of U.S. goods, and may result in increased exports. To the extent these innovations increase the demand for investment, however, they can have the opposite effect on the trade deficit. Nonetheless, each of these innovations increases the output of the economy, and hence the incomes of U.S. residents.

B. Trends in the United States' Balance of Payments

Foreign trade has become increasingly important to the United States economy. Figure 1 presents the value of exports from the United States and imports into the United States as a percentage of GDP for the period 1962-1997.(9) As depicted in Figure 1, exports and imports each have risen from less than six percent of GDP in 1962 to more than 14 percent in 1997. Figure 1 also shows that the United States generally was a net exporter of goods and services prior to 1982. Since that time, the United States has been a net importer of goods and services.


FIGURE 1


The net trade position of a country is commonly summarized by its current account. The U.S. current account as a whole, which compares exports of goods and services and income earned by U.S. persons on foreign investments to imports of goods and services and income earned by foreign persons on their investments in the United States (plus unilateral remittances), was positive as recently as 1981, but generally has been in deficit by over $90 billion per year nine times since 1984. Figure 2 reports the current account balance of the United States for the period 1963 through 1997 in nominal (non-inflation-adjusted) dollars.(10) Figure 2, like Figure 1, shows the United States' change in status from net exporter to net importer since the early 1980s. Figure 2 reflects a substantial reduction in the current account deficit for 1992. In that year, the United States received substantial payments from abroad related to the Persian Gulf war.


FIGURE 2


The aggregate data reported in Figures 1 and 2 mask differences in the trade position of various sectors of the economy. As explained above, the current account compares exports of goods and services and payments of income earned by U.S. persons on foreign investments to imports of goods and services and payments of income earned by foreign persons on their investments in the United States. Figures 3, 4, and 5 separately chart the nominal dollar value of exported and imported goods (Figure 3), exported and imported services (Figure 4), and investment income earned by U.S. and foreign persons (Figure 5).(11) The sum of the export curves in Figures 3, 4, and 5 less the sum of the import curves (plus unilateral remittances) equals the current account balance curve of Figure 2.

Figures 3, 4, and 5 reveal different trends. As has been widely reported, the merchandise (goods only) trade deficit has been over $100 billion per year since 1984. On the other hand, the United States has been a net exporter of services since the mid-1970s (Figure 4). Only since 1994 have payments of income to foreign persons on their U.S. investments exceeded U.S. receipts of income on investments abroad (Figure 5).


FIGURE 3


FIGURE 4


FIGURE 5


These aggregate data also do not reveal the extent to which growing trade flows result from trade between related parties. For example, a domestic company might ship components manufactured in the United States to its foreign subsidiary for final assembly and sale. Such shipments would be counted as exports from the United States. A domestic company might produce components abroad and ship them to the United States for final assembly and sale. Such shipments would be counted as imports to the United States. Likewise, a foreign parent company might ship components from abroad to its U.S. affiliate for final assembly and sale in the United States. Such shipments would be counted as imports into the United States. The foreign affiliate might ship components to another country for assembly and sale. Such shipments would be counted as exports from the United States.

The preceding paragraph suggests that intra-firm trade involves the shipment of components across borders. Other intra-firm trade may involve the shipment of raw materials abroad for manufacture abroad or shipment of finished goods to a foreign sales affiliate. The data do not permit such distinctions to be drawn. Nevertheless, the extent of this intra-firm cross-border trade is large and growing. In 1994, large foreign-owned domestic corporations reported sales of tangible goods to related foreign persons (exports) of $70.5 billion, a figure representing 14 percent of total U.S. merchandise exports in 1994. Large foreign-owned domestic corporations reported purchases of tangible goods from related foreign persons (imports) of $180.6 billion, a figure representing 27 percent of total U.S. merchandise imports in 1994.(12) Similarly, in 1994, U.S. multinational enterprises shipped $136.1 billion of goods to their foreign affiliates, a figure representing 26 percent of U.S. merchandise exports in 1994. Foreign affiliates of U.S. multinational enterprises $113.4 billion of goods to their U.S. parent enterprise, a figure representing 17 percent of U.S. merchandise imports in 1994.(13) Thus, in total, in 1994 intra-firm trade accounted for at least 40 percent of U.S. merchandise exports and 44 percent of U.S. merchandise imports.

The balance of payments accounts, presented in Table 1, are analogous to a sources and uses of funds statement of the United States with the rest of the world. As demonstrated in Part III.A. above, the current account balance, which consists primarily of the trade balance, should be exactly offset by the capital account balance, which measures the net inflow or outflow of capital to or from the United States. The difference between the current account surplus or deficit and the capital account deficit or surplus is recorded as a statistical discrepancy. Serious problems of measurement cause the accounts to be somewhat mismatched in practice, but basic patterns are unlikely to be significantly distorted by these problems.


TABLE 1


C. Trends in the United States' Capital Account

Overview of the United States' capital account

As explained in Part III.A., above, when the United States imports more than it exports, the dollars the United States uses to buy the imports must ultimately return to the United States as payment for U.S. exports or to purchase U.S. assets. As Figure 2 and Table 1 document the United States' current account has been in deficit since the early 1980s. Figure 6 plots gross (before depreciation) U.S. investment and gross U.S. saving as a percentage of GDP for the period 1959-1998.(14) Figure 6 also plots net foreign investment as a percentage of GDP. In Figure 6, when the United States is a net exporter of capital, net foreign investment is measured as a positive number and when the United States is a net importer of foreign capital net foreign investment is measured as a negative number. Net foreign investment became a larger proportion of the economy since 1982. At the same time, the United States changed from being a modest exporter of capital in relation to GDP to being a large importer of capital. Net foreign investment has become a larger proportion of the economy and a more significant proportion of total domestic investment than in the past. In 1997, gross investment in the United States was $1,351 billion and net foreign investment was $141 billion, or 10.4 percent of gross domestic investment. In 1993, net foreign investment comprised 8.9 percent of gross domestic investment.


FIGURE 6


The net foreign investment in the United States is measured by the United States' capital account. The capital account measures the increase in U.S. assets abroad compared to the increase in foreign assets in the United States. Figure 7 plots the annual increase of U.S. assets abroad and of foreign assets in the United States in nominal dollars for the period 1962-1997.(15)


FIGURE 7


Growth in foreign-owned assets in the United States(16)

The amount of foreign-owned assets in the United States grew more than 700 percent between 1975 and 1988 and more than 300 percent between 1980 and 1988.(17) The total amount of foreign-owned assets in the United States exceeded $4.5 trillion by the end of 1996.(18) The recorded value of U.S.-owned assets abroad grew less rapidly during the same period. The Department of Commerce reports that in 1975 the amount of U.S.-owned assets abroad exceeded foreign-owned assets in the United States by $74 billion. By the end of 1988, however, the situation had reversed, so that the amount of foreign-owned assets in the United States exceeded U.S.-owned assets abroad by $162 billion. By 1996, the amount of foreign-owned assets in the United States exceeded U.S.-owned assets abroad by $871 billion.(19) These investments are measured by their book value. Some argue that the market value of U.S.-owned assets abroad is similar to, or greater than, the market value of foreign-owned assets in the United States, if market values were measured accurately.(20) Figures 8 and 9 display the value of U.S.-owned assets abroad and foreign-owned assets in the United States for selected years measured under both current (or book) cost and based on estimates of current market values. Whether this argument is correct with respect to the current net investment position, it is clear that foreign-owned U.S. assets are growing more rapidly than U.S.-owned assets abroad as depicted in Figure 7.


FIGURE 8


FIGURE 9


Foreign assets in the United States (and U.S. assets abroad) can be categorized as direct investment, non-direct investment, and official assets. Direct investment constitutes assets over which the owner has direct control. The Department of Commerce defines an investment as direct when a single person owns or controls, directly or indirectly, at least 10 percent of the voting securities of a corporate enterprise or the equivalent interests in an unincorporated business. Foreign persons held direct investments of $729 billion in the United States in 1996, having grown from $83 billion in 1980.(21)

The largest category of investment is non-direct investment held by private (non-governmental) foreign investors, commonly referred to as portfolio investment. This category consists mostly of holdings of corporate equities, corporate and government bonds, and bank deposits. The portfolio investor generally does not have control over the assets that underlie the financial claims. In 1996, portfolio assets of foreign persons in the United States were more than triple the recorded value of direct investment, $2,576 billion compared to $729 billion, respectively.(22) Bank deposits account for approximately one-third of this total, and reflect, in part, the increasingly global nature of banking activities. Figure 10 reports the dollar value of foreign holdings of selected U.S. assets, both portfolio investment and direct investment, for 1984, 1990, and 1996. Foreign investment in bonds, corporate equities, and bank deposits, like other types of financial investment, provide a source of funds for investment in the United States but also represent a claim on future U.S. resources.

The final category of foreign-owned U.S. assets is official assets: U.S. assets held by governments, central banking systems, and certain international organizations. The foreign currency reserves of other governments and banking systems, for example, are treated as official assets. Levels of foreign-held official assets have grown more slowly than foreign-held direct and portfolio investment of private investors.

The value of investments by private U.S. persons abroad has grown from $295.1 billion in 1980 to $3,477 billion in 1996.(23) This growth has not been as rapid as the growth in the value of investments by foreign persons in the United States.

IV. ECONOMIC ISSUES IN THE TAXATION OF
INTERNATIONAL TRANSACTIONS

A. Overview

As the previous section documents, cross border trade and investment has grown substantially over the past decade. International investment plays an important role in determining the total amount of worldwide income as well as the distribution of income across nations. In addition, international investment flows can substantially influence the distribution of capital and labor income within nations. Because each government levies taxes by its own method and at its own rates, the resulting system of international taxation can distort investment and contribute to reductions in worldwide economic welfare. A government's tax policies affect the distribution of income directly, by collecting tax from foreigners earning income within its borders and from residents earning income overseas, and indirectly by inducing capital movements across national borders.(24)

Analysts usually assess any system of taxation in terms of four general principles.
