Fill out Form 1116 (Foreign Tax Credit) online
Form 1116 is used to claim a tax credit for income taxes paid or accrued to a foreign country or U.S. possession. The foreign tax credit reduces your U.S. tax liability on foreign-source income, preventing double taxation on the same income.
How to fill out Form 1116 (Foreign Tax Credit)
Identify the category of income
Determine which category of foreign-source income applies: general category, passive category, or other specific categories listed on the form. File a separate Form 1116 for each category.
Calculate foreign-source taxable income
Enter your gross foreign-source income for the category and subtract any definitely allocable deductions. This determines the taxable income from foreign sources used to calculate the credit limitation.
Enter foreign taxes paid or accrued
Report the foreign income taxes paid or accrued during the tax year. Convert amounts in foreign currency to U.S. dollars. Include taxes withheld at source and taxes paid directly to foreign governments.
Compute the foreign tax credit limitation
Calculate the maximum credit allowed by multiplying your U.S. tax liability by the ratio of foreign-source taxable income to worldwide taxable income. The credit cannot exceed this limitation.
