We have created an interactive map which tracks U.S. multinational corporations’ reported foreign taxable income, taxes paid, and average tax rate from 1992 to 2010 in over 90 countries using all available IRS data from Form 1118 .

Use the drop down options on the map to select country, year, and data category (i.e. foreign income, foreign taxes paid, and effective tax rates). Additional information below the map.

The United States’ “worldwide” system of corporate taxation requires multinational corporations to pay taxes twice, first to the foreign country in which they do business and then to the IRS after they repatriate their profits.

For example, if a subsidiary of a U.S. firm earns $100 in profits in England, it pays the British income tax rate of 21 percent (or $21) on those profits. Since our system gives companies a credit for the taxes they pay to other countries, the additional U.S. tax the firm is required to pay is equal to the difference between the U.S. rate of 35 percent and the British rate of 21 percent—$14. Between the two nations, the U.S. firm will have paid a total of 35 percent in taxes on those foreign profits once those profits are brought back to the United States.

In order to take advantage of the foreign tax credit allowed under our tax system, companies are required to annually file Form 1118.

On Form 1118, corporations need to report how much they earn in each country in which they operate and how much they pay each country in taxes. We use this form to collect this data.

A few key points about the data:

Multinational corporations reported paying $128 billion in corporate taxes to foreign countries on $470 billion of taxable income in 2010, according to most recent IRS data.

Over the past eighteen years, foreign corporate taxable income has grown by about 250 percent and foreign corporate taxes paid by 265 percent, while the effective tax rate has remained around 26 percent.

The effective tax rate on foreign income was 27.2 percent in 2010, prior to paying additional taxes to the United States.

More than 60 percent of all reported foreign taxable income was earned in Europe and Asia in 2010.
