Summary

When the President finds that a foreign country taxes U.S. citizens or U.S. companies in a discriminatory or extraterritorial way, the President must announce it. After that announcement, the tax rates in certain parts of the U.S. tax code (sections 1, 3, 11, 801, 831, 852, 871, and 881) for citizens and companies of that foreign country are doubled for that tax year and for later years. The doubled tax cannot raise a taxpayer’s tax to more than 80% of their taxable income, calculated without the deductions allowed under section 151 and part VIII of subchapter B. If the President later finds the foreign country has fixed those laws and removed the discriminatory taxes, the President must announce that too, and the doubled rates stop applying to taxable years that begin after that announcement.

Internal Revenue Code — Source: USLM XML via OLRC

Whenever the President finds that, under the laws of any foreign country, citizens or corporations of the United States are being subjected to discriminatory or extraterritorial taxes, the President shall so proclaim and the rates of tax imposed by section 1, 3, 11, 801, 831, 852, 871, and 881 shall, for the taxable year during which such proclamation is made and for each taxable year thereafter, be doubled in the case of each citizen and corporation of such foreign country; but the tax at such doubled rate shall be considered as imposed by such sections as the case may be. In no case shall this section operate to increase the taxes imposed by such sections (computed without regard to this section) to an amount in excess of 80 percent of the taxable income of the taxpayer (computed without regard to the deductions allowable under section 151 and under part VIII of subchapter B). Whenever the President finds that the laws of any foreign country with respect to which the President has made a proclamation under the preceding provisions of this section have been modified so that discriminatory and extraterritorial taxes applicable to citizens and corporations of the United States have been removed, he shall so proclaim, and the provisions of this section providing for doubled rates of tax shall not apply to any citizen or corporation of such foreign country with respect to any taxable year beginning after such proclamation is made.
