Glossary of International Tax Terms

The language of international tax experts can be confusing, even to experienced audiences. To help decision makers understand the complex issues of international taxation, below are definitions of some of the most frequently used terms.

Active Income: Income earned by a corporation through the conduct of a trade or business activity (in contrast to a passive investment activity).

Active Financing Income Rule: U.S. tax rules generally defer taxation of income from an active foreign business until that income is remitted to the U.S. parent. Under subpart F rules, interest and related income of a foreign subsidiary generally are subject to current taxation without benefit of deferral. These rules historically have aimed at requiring current taxation of income that is passive or easily moveable, although some forms of active income are also subject to these rules. The active financing income rule in present law is a temporary measure to permit deferral of certain types of income derived from the active conduct of a banking, finance, or insurance business. This provision, most recently extended in January 2013, expires for taxable years beginning after December 31, 2013.

CFC Look-Through Rule: U.S. tax rules generally defer taxation of income from an active foreign business until that income is remitted to the U.S. parent. Under subpart F rules, interest and related income of a foreign subsidiary generally are subject to current taxation without benefit of deferral. The CFC look-though rule provides that payments of dividends, interest, rents and royalties between related controlled foreign corporations (CFCs) will not give rise to subpart F income (thereby permitting deferral) to the extent the payments come from active, nonsubpart F earnings of the payer CFC. In effect, the provision "looks through" the form of payment to the underlying source of income. The provision was adopted to permit foreign subsidiaries of U.S. companies to redeploy active foreign earnings in a manner similar to that permitted by most U.S. trading partners. This provision, a temporary measure most recently extended in January 2013, expires for taxable years beginning after December 31, 2013.

Check-the-Box: The "check-the-box" election allows an American company to choose how an entity it owns, either domestic or foreign, will be treated for U.S. tax purposes. In general, U.S. tax rules classify a business organization as either a corporation or a flow-through entity, such as a partnership. When a business organization is treated as a flow-through entity, all income flows through to its owners where the U.S. tax effects are determined. Prior to the check-the-box election, the determination of whether a business organization would be considered a corporation or flow-through entity was based on a complex review of its characteristics. This led to uncertainty and administrative burden on both taxpayers and the IRS to determine the appropriate classification of a business organization. In an effort to resolve these issues the Clinton Administration Treasury Department created the check-the-box election.

Controlled Foreign Corporation (CFC): A foreign corporation in which more than 50% of the voting power or value of the stock is held by U.S. shareholders. Only a U.S. shareholder that owns 10% or more of the stock of the foreign corporation is included in this determination. Subpart F rules apply to foreign subsidiaries that are CFCs.

Deferral: In order to maintain the ability of worldwide American companies to compete against their foreign-based competition and in conformance with tax policies of our trading partners, the U.S. government defers collecting taxes on earnings of the foreign subsidiaries of worldwide American companies until those earnings are actually paid to the U.S. parent, with some exceptions (see "Subpart F"). Most frequently, these foreign earnings will be paid as a cash dividend to the U.S. parent company. This method of taxation mirrors the tax treatment of individual shareholders in a domestic corporation who are not taxed on the earnings of the corporation until they receive a distribution from the corporation. All member countries in the Organization for Economic Cooperation and Development (OECD) and other developed nations that tax the worldwide earnings of their globally operating corporations permit some form of deferral.

Exemption System See "Territorial Tax System" below.

Foreign Base Company Income (FBCI): A type of foreign income that is subject to current U.S. taxation under subpart F rules whether or not distributed to U.S. shareholders. The four categories of FBCI are:

  • Foreign personal holding company income is defined as income which consists of dividends, interest, royalties, rents, and other kinds of investment income;
  • Foreign base company sales income is defined as income which is derived from the purchase and sale of property involving a related party where the property originates outside the country in which the controlled foreign corporation is organized and is sold for use outside such foreign country;
  • Foreign base company services income is defined as services income arising on behalf of a related person outside the country in which the controlled foreign corporation is organized; and
  • Foreign base company oil related income is defined as income arising from the sale of oil and gas products except where the income is earned in the country in which it is extracted.

Foreign Tax Credit: To avoid double taxation of foreign income, the U.S. provides a credit against U.S. income tax for income tax paid to the host country. Without this credit, significant double taxation would make foreign investments noncompetitive for worldwide American companies. The foreign tax credit is subject to various limitations to ensure that a U.S. company pays at least as much tax on its worldwide income as it would pay on the same income earned at home.

Passive Income: Income earned in the form of interest, dividends, and similar investment income through investment activities of the taxpayer (as opposed to active income earned from the taxpayer's conduct of a trade or business activity).

Subpart F: 10-percent U.S. shareholders of a controlled foreign corporation (CFC) are subject to U.S. tax currently on certain income earned by the CFC whether or not such income is actually distributed to the U.S. parent (i.e., without the advantage of “deferral”). These rules historically have aimed at requiring current taxation of income that is passive or easily moveable, although some forms of active income are also subject to these rules. Income subject to tax under subpart F includes certain insurance income and "foreign base company income" (defined above). U.S. anti-deferral rules are the most restrictive of our major trading partners and extend to many types of active business income.

Territorial Tax System: Under a territorial or "exemption" system, the active foreign earnings of a foreign subsidiary are not subject to tax by the home country when paid as a cash dividend to the parent corporation. Among advanced economies, 28 of the 34 Organization for Economic Cooperation and Development (OECD) member countries as following an exemption approach, with the remainder following a worldwide approach. Exemption countries in the OECD are Australia, Austria, Belgium, Canada, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Japan, Italy, Luxembourg, Netherlands, New Zealand, Norway, Poland, Portugal, Slovak Republic, Slovenia, Spain, Sweden, Switzerland, Turkey, and the United Kingdom.

Worldwide Tax System: Under a worldwide system of taxation, all foreign earnings of a domestic corporation are subject to tax in the home country. In practice, countries following a worldwide principle, including the United States, permit deferral on most forms of active foreign earnings until such income is paid to the domestic corporation. Within the 34 countries of the Organization for Economic Cooperation and Development (OECD), five countries in addition to the United States follow a worldwide approach, with the other 28 countries following an exemption approach. Worldwide countries in the OECD are Chile, Ireland, Israel, Korea, Mexico, and the United States.

Facts about Deferral
U.S. tax rules significantly affect the ability of American companies to compete in foreign markets. These rules include a provision known as “deferral,” which is a key pro-competitive international tax rule for American companies. Click Here to Learn More
Did You Know?
Myth: Deferral erodes the U.S. tax base.
Fact: Deferral supports U.S. economic competitiveness by maintaining a measure of comparability between the taxes paid by globally engaged American companies and foreign-based international companies on their foreign operations.
