Schedule C (Form 1116): Foreign Tax Redeterminations

Schedule C (Form 1116), Foreign Tax Redeterminations, is a three-page schedule of Form 1116, Foreign Tax Credit (Individual, Estate, or Trust). It records changes to foreign taxes for the U.S. tax years to which those taxes relate, which the form calls relation back years: an increase in foreign taxes accrued in Part I and a decrease in foreign taxes paid or accrued in Part II, each entered by payor.

Part III shows, for each relation back year, the redetermined foreign taxes against the amounts on the original or amended return, and the foreign tax credit (FTC) claimed before and after the redetermination. Part IV shows the change in U.S. tax liability. Part V is annual reporting for contested foreign taxes for which an election under Regulations section 1.905-1(d)(4) was made to claim a provisional foreign tax credit.

The form says to use a separate Schedule C (Form 1116) for each applicable category of income and to check only one box on each schedule. It does not print its instructions: it says "See separate instructions" and points to www.irs.gov/Form1116. The PDF can be filled out free in the browser on this page and downloaded without an account.

What's on Schedule C (Form 1116)

Header and category boxes

Calendar or other tax year, name, identifying number, boxes a to g for the category of income, and lines h and i for the country code of a sanctioned country (box e) or treaty country (box f).

Part I: increase in foreign taxes accrued

Columns 1 to 13 cover the relation back year, payor name and EIN or reference ID, country code, dates, payor's income, additional tax in local and functional currency, conversion rate, U.S. dollar amounts and revised tax accrued, with a subtotal per year.

Part II: decrease in foreign taxes

The same layout for tax refunded or deemed refunded. Column 12 subtracts column 10 from column 11, and column 13 is a box to check if the section 905(c)(2) two-year rule applies.

Part III: change in foreign taxes and FTC

For each relation back year: redetermined foreign taxes, foreign taxes per the original or amended return, and the FTC claimed per that return and after redetermination.

Part IV: change in U.S. tax liability

For each relation back year or affected tax year: total redetermined U.S. tax liability, total U.S. tax liability per the original or amended return, and the difference.

Part V: contested taxes

Up to five rows with the relation back year, payor, reference ID, country code, amount provisionally claimed, whether the contest is ongoing or resolved, the date resolved, and any tax refunded or additional tax paid.

How to fill out Schedule C (Form 1116)

  1. 1

    Header and one category box

    Enter the tax year, the name and the identifying number shown on page 1 of the tax return. Check only one category box. If box e or f is checked, enter the country code on line h or i.

  2. 2

    Part I by payor and year

    The form says to enter redetermined amounts by payor for each separate relation back year, starting with the most recent, followed by a subtotal for each year. Column 10 divides column 7 by column 9, and column 12 adds columns 10 and 11.

  3. 3

    Part II for refunds

    Enter refunded or deemed refunded amounts the same way, by payor and relation back year. Column 10 divides column 7 by column 9, and column 12 subtracts column 10 from column 11.

  4. 4

    Part III: credit before and after

    For each relation back year, enter the redetermined foreign taxes, the foreign taxes per the original or amended return, and the FTC claimed before and after the redetermination.

  5. 5

    Part IV: U.S. tax difference

    Enter the total redetermined U.S. tax liability and the total per the original or amended return for each affected year, then subtract column 3 from column 2.

  6. 6

    Part V: contested taxes

    For each contested tax with a provisional credit election, enter the year, payor, reference ID, country code and amount claimed, check ongoing or resolved, and add the resolution date and any refund or additional tax.
