What is the Foreign Tax Credit (FTC)?
– The Foreign Tax Credit (FTC) is a U.S. federal tax benefit that reduces the U.S. income tax you owe on foreign‑sourced income by the amount of income tax you actually paid (or accrued) to a foreign country or a U.S. possession. Its purpose is to prevent double taxation when the same income is taxed both abroad and by the United States. (Sources: Investopedia; IRS Publication 514)
Who can claim it?
– U.S. citizens and resident aliens.
– Estates and trusts.
– Certain nonresident aliens in limited situations (e.g., bona fide residents of Puerto Rico for the whole year or foreign taxes connected to a U.S. trade or business).
– Note: If you use the Foreign Earned Income Exclusion (FEIE) for a portion of your wages, you cannot claim the FTC for taxes on the excluded income. (IRS, Investopedia)
Which foreign taxes qualify?
– Generally: income taxes and taxes in lieu of income tax (including foreign wages, dividends, interest, royalties).
– Qualifying taxes must be:
– Imposed on you by a foreign country or U.S. possession,
– Not a payment for a specific economic benefit, and
– Substantially similar to a U.S. income tax.
– Taxes that normally do NOT qualify: foreign real or personal property taxes (these may be deductible on Schedule A or as business expenses if appropriate). (IRS Publication 514; Investopedia)
Refundable vs non‑refundable
– The FTC is generally a non‑refundable credit: it reduces tax liability dollar‑for‑dollar but won’t produce a refund beyond zero.
– However, unused FTC amounts can be carried back 1 year and forward up to 10 years. This allows you to use foreign taxes paid in a different tax year against your U.S. tax liability. (IRS Publication 514; Form 1116 instructions)
Credit vs. Deduction — which is better?
– Credit: directly reduces U.S. tax liability, normally more valuable.
– Deduction: reduces taxable income, so the actual tax savings equals your marginal tax rate × deduction amount.
– You must choose to take either a credit or a deduction for ALL qualifying foreign taxes in a given year — you cannot split the same tax between credit and deduction or mix for different foreign taxes. (Investopedia; IRS)
How the FTC limit works (concept and example)
– The credit is limited so you can’t use it to reduce U.S. tax on U.S.‑source income. The usual limit formula is:
FTC limit = (Foreign‑source taxable income ÷ Worldwide taxable income) × U.S. tax on worldwide taxable income
– You claim the smaller of:
– The actual foreign tax paid (or accrued), or
– The calculated FTC limit above.
– Example: Worldwide taxable income = $200,000; foreign‑source taxable income = $50,000; U.S. tax on worldwide taxable income = $40,000.
FTC limit = (50,000 ÷ 200,000) × 40,000 = 10,000.
If you paid $12,000 in qualifying foreign tax, you can claim $10,000 as a credit now; the $2,000 unused portion may be carried back 1 year or forward up to 10 years. (IRS Form 1116 guidance)
Key practical points and requirements
– Filing requirement: To claim the credit you typically must complete Form 1116 (Foreign Tax Credit) and attach it to Form 1040. There are exceptions:
– If your total qualified foreign taxes are $300 or less ($600 if married filing jointly) and you meet the other conditions, you may be able to claim the credit directly on Form 1040 without Form 1116. (Form 1116 instructions)
– If you qualify for certain other exceptions, you might not need Form 1116 — review the Form 1116 instructions or IRS Topic No. 856.
– Categories (baskets): Foreign income is grouped into categories (for example, general category and passive category). The limit is calculated separately for each category. (IRS Publication 514)
– Currency conversion: Foreign taxes are usually paid in a foreign currency. Convert them into U.S. dollars using the exchange rate in effect on the date you paid the tax, the tax was withheld, or you made an estimated tax payment. If taxes were paid throughout the year, you can generally use an appropriate yearly average exchange rate. (IRS guidance)
– Documentation: Keep foreign tax returns, foreign tax withholding statements, and proof of payment. You may need these to substantiate your claim.
– Interaction with FEIE: If you elect the Foreign Earned Income Exclusion (Form 2555) you can’t claim FTC on the excluded income (and claiming both could cause the IRS to revoke one or both elections). Consider whether credit or exclusion gives better overall U.S. tax outcome. (IRS Publication 54; Investopedia)
– State tax treatment: State tax treatment of foreign tax credits varies. Most states do not allow a credit for foreign taxes paid — check your state rules.
Step‑by‑step practical procedure to claim the FTC
1. Confirm eligibility
– You are a U.S. citizen/resident alien (or eligible estate/trust), and you paid or accrued foreign income tax to a foreign country or U.S. possession on income that is also subject to U.S. tax.
2. Gather documentation
– Foreign tax return/wage statements (e.g., foreign Form(s) showing tax withheld), receipts or bank statements showing tax payments, proof of residency or source of income by country.
3. Decide credit vs deduction
– Run a quick comparison: credit reduces U.S. tax dollar‑for‑dollar; deduction reduces taxable income. Calculate both (or consult a tax pro) — usually the credit is better unless the foreign rate is lower and other tax planning considerations make a deduction preferable.
4. Determine qualifying foreign taxes and amounts
– Identify amounts that meet the IRS definition of a qualifying income tax or taxes in lieu of income tax.
5. Classify foreign income into categories (baskets)
– Separate general income (wages, business income) and passive income (interest, dividends, rent), etc., as required.
6. Convert amounts to U.S. dollars
– Use the exchange rate at the date of payment, withholding, or an appropriate annual average.
7. Compute foreign‑source taxable income and the FTC limit for each category
– Apply the limit formula separately to each category.
8. Prepare and file Form 1116 (if required)
– Complete Form 1116 for each category (or use the small amount exception to report directly on Form 1040 if eligible). Attach Form 1116 to your Form 1040 and include any supporting documentation.
9. If credit exceeds the limit
– Track the unused foreign tax amount for carryback (1 year) or carryforward (10 years). Use Form 1116 in the year you utilize a carryback/forward.
10. Keep records
– Maintain documentation of foreign tax payments, exchange rates used, and the computation, for at least the statute of limitations (generally 3 years), longer if you carry unused credits.
Common warnings and pitfalls
– Don’t claim FTC for taxes on income you excluded with the FEIE — that’s not allowed.
– Don’t double‑claim: you cannot both deduct and credit the same foreign tax.
– Treaties: tax treaties between the U.S. and the foreign country may affect whether withholding was proper or whether you owe additional U.S. tax; consider treaty relief before claiming FTC.
– State taxes: a U.S. state generally won’t allow a FTC for foreign income taxes; review state law.
– Accurate categorization matters: mixing income across baskets can reduce allowable credit. When in doubt, consult a tax professional.
Example (simple)
– Worldwide taxable income: $120,000
– Foreign‑source taxable income: $30,000
– U.S. tax on worldwide income: $24,000
– Foreign tax paid: $6,000
– FTC limit = (30,000 ÷ 120,000) × 24,000 = 6,000
– Claimable FTC = smaller of foreign tax paid ($6,000) and limit ($6,000) = $6,000 (no carryover).
When to consult a tax professional
– You have multiple foreign jurisdictions, complicated income types, foreign tax credits carried forward/back, treaty issues, or you are unsure how to allocate income to foreign vs. U.S. sources. The FTC rules (baskets, sourcing rules, and limitations) can be complex and mistakes may be costly.
Bottom line
– The Foreign Tax Credit reduces U.S. income tax to offset foreign income taxes paid, preventing double taxation. It is usually preferable to a deduction, but subject to a limit that depends on the ratio of foreign‑source income to worldwide income. Most taxpayers claiming the credit must file Form 1116, must not claim both an exclusion and a credit for the same income, and should carefully document foreign taxes and currency conversions. Unused credit amounts can be carried back one year or forward ten years.
