Schedule L (Form 1118): Foreign Tax Redeterminations

Schedule L (Form 1118), Foreign Tax Redeterminations, is a four-page schedule attached to Form 1118, Foreign Tax Credit, Corporations. The IRS About page says it is used to report foreign tax redeterminations that occurred in the current taxable year and that relate to prior taxable years.

The instructions define a foreign tax redetermination as a change in the liability for foreign income taxes, for example when accrued foreign taxes differ from the amounts claimed as credits, are not paid within 24 months after the close of the tax year they relate to, or are fully or partially refunded. Parts I and II report increases and decreases by payor entity, Parts III and IV report the changes in inclusions, credits and U.S. tax liability, and Part V covers contested taxes.

The schedule says "Attach to Form 1118." You can fill out Schedule L free in your browser on this page and download it without an account.

What's on Schedule L (Form 1118)

Lines a to d

The separate category code, the country code for a sanctioned country when code 901j is used, the treaty country code when an RBT code is used, and the box for the Regulations section 1.905-5(e) election.

Part I: increase in foreign taxes accrued

Fourteen columns by payor entity and relation back year: payor and owner details, country code, dates, income subject to foreign tax, additional tax in local and functional currency, conversion rate, U.S. dollar amounts and check boxes.

Part II: decrease in foreign taxes

The same layout for taxes refunded or deemed refunded, with a box for when the section 905(c)(2) two-year rule applies.

Part III: change in inclusions and credits

Seventeen columns comparing redetermined and original amounts of direct section 901 and 903 taxes, section 951(a)(1) and 951A inclusions, deemed paid taxes and foreign tax credit claimed, on an overall taxpayer basis.

Part IV: change in U.S. tax liability

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

Part V: annual reporting for contested taxes

Relation back year, payor entity, reference ID number, country, amount provisionally claimed, whether the contest is ongoing or resolved, the date resolved, tax refunded and additional tax paid.

How to fill out Schedule L (Form 1118)

  1. 1

    Complete the header

    Enter the tax year, the corporation's name and EIN. On line a, enter the same separate category code shown on the Form 1118 the schedule relates to, and complete lines b to d if they apply.

  2. 2

    Report increases in Part I

    Enter the ending date of each relation back year, the payor entity's name and EIN or a reference ID number, the country code, dates and amounts. The instructions say not to enter "FOREIGNUS" or "APPLIED FOR" for the EIN.

  3. 3

    Use the divide-by exchange rate

    The instructions say to report exchange rates as the units of foreign currency that equal one U.S. dollar, rounded to at least four places, not as U.S. dollars per unit of foreign currency.

  4. 4

    Report decreases in Part II

    Enter refunded or deemed refunded amounts. For taxes deemed refunded under the two-year rule, the instructions say to enter the date 24 months after the close of the tax year and check column 13.

  5. 5

    Show the overall effect in Parts III and IV

    Report the redetermined and original amounts on an overall taxpayer basis. The instructions say Part IV is completed only once, in the "TOTAL" version of the schedule.

  6. 6

    Update contested taxes in Part V

    For each contested tax with a provisional credit, enter the reference ID number from Form 7204, check ongoing or resolved, and enter the date resolved, tax refunded and additional tax paid if any.

The TOTAL schedule

The instructions say the "TOTAL" Schedule L is filed with the same category of income that completes Form 1118, Schedule B, Part III.

Amended returns
