Title 26 › Subtitle A — Income Taxes › CHAPTER 1 — NORMAL TAXES AND SURTAXES › Subchapter N — Tax Based on Income From Sources Within or Without the United States › PART II — NONRESIDENT ALIENS AND FOREIGN CORPORATIONS › Subpart D — Miscellaneous Provisions › § 891
If the President finds a foreign country is taxing U.S. citizens or companies unfairly or beyond its borders, he must proclaim it. For the taxable year of that proclamation and every year after, the tax rates in sections 1, 3, 11, 801, 831, 852, 871, and 881 that apply to citizens and corporations of that foreign country are doubled and treated as if imposed by those sections. The higher tax cannot make the taxpayer pay more than 80 percent of taxable income, calculated without the increase and without counting deductions allowed by section 151 and by part VIII of subchapter B. If the President later proclaims the foreign laws were fixed, the doubling stops for taxable years that begin after that proclamation.
