Implementation Guide for Tax Professionals
Identify Foreign Taxes Paid or Accrued
Foreign taxes eligible for the FTC must be: (1) a legal and actual foreign tax liability; (2) imposed on income; (3) paid or accrued by the taxpayer. Foreign taxes that are refundable, subsidized, or paid on excluded income (FEIE) do not qualify. The credit is generally more valuable than the deduction. [IRC §901]
Categorize Income into Baskets
Foreign income must be separated into income baskets for the FTC limitation: (1) passive category income (dividends, interest, rents, royalties); (2) general category income (wages, business income); (3) foreign branch category income; (4) GILTI; (5) Section 901(j) income. Excess credits in one basket cannot offset the limitation in another basket.
Calculate the FTC Limitation
FTC limitation = U.S. tax × (foreign source income ÷ worldwide income). Calculate separately for each basket. The FTC cannot exceed the U.S. tax attributable to the foreign income. Excess FTCs carry back 1 year and forward 10 years. Track carryforwards carefully — they expire after 10 years.
Complete Form 1116
Complete a separate Form 1116 for each income basket. Part I: foreign taxes paid or accrued. Part II: foreign income and deductions. Part III: FTC limitation calculation. Part IV: summary and carryover. If total foreign taxes are $300 or less ($600 MFJ) and all income is passive, the simplified method (no Form 1116) may be available.
Frequently Asked Questions
What is the Foreign Tax Credit?
The Foreign Tax Credit (FTC) allows U.S. taxpayers to offset U.S. tax on foreign income by the amount of foreign taxes paid or accrued. The credit prevents double taxation of the same income by two countries. The FTC is limited to the U.S. tax on the foreign income (the FTC limitation). [IRC §901]
What are the FTC income baskets?
Foreign income is separated into baskets for FTC limitation purposes: (1) passive category income (dividends, interest, rents, royalties); (2) general category income (wages, business income); (3) foreign branch category income; (4) GILTI; (5) Section 901(j) income (from countries on the terrorism list). Excess credits in one basket cannot offset the limitation in another basket.
What is the FTC limitation?
The FTC limitation = U.S. tax × (foreign source income ÷ worldwide income). The FTC cannot exceed the U.S. tax attributable to the foreign income. Excess FTCs carry back 1 year and forward 10 years. The limitation is calculated separately for each income basket.
When can the FTC be claimed without Form 1116?
Taxpayers can claim the FTC without filing Form 1116 (the simplified method) if: (1) total foreign taxes are $300 or less ($600 for MFJ); (2) all foreign income is passive income; and (3) all foreign income and taxes are reported on Form 1099-DIV or 1099-INT. The simplified method is faster but may result in a lower credit.
How does the FTC interact with tax treaties?
Tax treaties may reduce foreign withholding taxes, which reduces the available FTC. However, treaties may also provide other benefits (e.g., exempting certain income from foreign tax). The taxpayer must claim treaty benefits on the foreign return to reduce withholding to the treaty rate. If excess withholding occurs, the taxpayer must file for a refund from the foreign country.
