Foreign Tax Credit (2026)

Foreign taxes paid can dollar-reduce U.S. tax—within limits

When you pay foreign income tax on foreign-source wages, business profit, or passive income, the foreign tax credit (FTC) on Form 1116 reduces U.S. tax on that income instead of excluding it under FEIE. High European or Canadian rates often make FTC better than excluding $132,900 under FEIE when foreign tax exceeds U.S. tax on the same dollars.

Enter foreign-source income by basket, foreign taxes paid, total U.S. taxable income, and pre-credit U.S. tax. Compare residual U.S. tax to FEIE scenario in the FEIE calculator.

2026 planning contrast

FEIE cap $132,900 removes income from tax entirely when qualified. FTC keeps income taxable but credits foreign tax up to U.S. tax on foreign income. At 40% foreign rate on $200,000 earned abroad, foreign tax $80,000 may exceed U.S. tax on that income—FTC wipes U.S. layer; FEIE would leave $67,100 taxable after exclusion cap.

How to use the calculator

Step 1 — Enter foreign-source income and U.S. tax

Wages abroad, foreign dividends, rental in foreign country.

Step 2 — Enter foreign taxes paid

Withholding plus year-end foreign return payments converted to USD.

Step 3 — Apply limitation ratio

Credit capped at U.S. tax attributable to foreign income; see carryforward remainder.

Earned vs passive baskets

General category (earned) and passive category credits do not cross-apply excess easily. Dividends with foreign withholding use passive basket—link dividend tax calculator.

Treaty benefits

Treaties may reassign sourcing or cap withholding—calculator uses numbers you enter post-treaty.

Worked example

$100,000 foreign wages, $25,000 foreign tax paid, U.S. tax on foreign slice $22,000 before credit → credit limited to $22,000; $3,000 excess carries forward. FEIE path might exclude $100,000 if under cap and qualified—zero U.S. on wages but no credit for foreign tax paid (foreign country still keeps $25,000).

Common mistakes

• Claiming FTC and FEIE on same dollar of wages
• Including VAT in foreign taxes paid
• Ignoring basket limitations on passive income
• Using wrong exchange rate for foreign tax paid

Currency and conversion

Translate foreign taxes paid at IRS yearly average exchange rate or payment-date rate per Form 1116 instructions—consistent method required. Refunds of foreign tax in later year may require amending prior FTC claims.

High-tax country worked examples

U.K. or Germany wage tax often exceeds U.S. tax on same income—FTC eliminates U.S. residual; FEIE would forfeit foreign tax credit on same dollars. Choosing FEIE locks out FTC on excluded amount for that year—five-year lockout on revoking FEIE without IRS consent in some circumstances after claiming.

Foreign tax redetermination (audit adjustment abroad) requires U.S. return amendment and FTC recalculation—carryforward and carryback years affected.

Reading your results for foreign tax credit

The interactive panel above shows a transparent calculation trace in cents—use it to sanity-check inputs before you rely on any number for decisions. Tax software at filing time may differ when every credit, limitation, and state conformity rule is applied in full. Treat output here as structured planning math aligned to 2026 federal reference data where noted, not as e-file output or professional advice.

When your situation includes items this specialized tool simplifies—multiple entities, prior-year carryforwards, treaty elections, or state nonconformity—layer those facts manually or with a preparer. The goal is to narrow uncertainty enough to ask better questions, not to eliminate the need for review when dollars are material.

Recordkeeping that survives scrutiny

Keep source documents (forms, statements, logs, confirmations) that support every input you typed. IRS and state audits often start from third-party reporting; your job is to reconcile 1099s, K-1s, and broker exports to the story you file. Digital backups with dates beat reconstructed spreadsheets created after an notice arrives.

For foreign tax credit, retain worksheets year to year when carryforwards exist—loss carryovers, credit carryforwards, passive loss suspensions, and basis schedules die silently if you change preparers and lose history.

2026 federal brackets and payroll context

Ordinary income tax brackets and standard deductions for 2026 follow IRS Rev. Proc. 2025-32 ($16,100 single / $32,200 joint standard deduction; seven marginal rates from 10% to 37%). Social Security tax applies at 6.2% on wages up to the $184,500 wage base; Medicare continues at 1.45% with Additional Medicare Tax above threshold wages. These layers stack independently from specialized rules modeled in this foreign tax credit tool—run the federal income tax calculator when you need the full return picture.

Quarterly estimated tax may be required when withholding does not cover liability—see the quarterly estimated tax calculator. Year-end refund or balance due comparisons belong in the tax refund estimator once withholding and payments are known.

Before filing season

Reconcile this foreign tax credit calculator estimate against draft Form 1040 lines and attached schedules your software produces. Look for mismatches in basis, carryforwards, and state add-backs—the first pass with a specialized calculator often misses secondary limits that full return software catches. Update inputs when you receive final 1099s, K-1s, and corrected broker statements; January revisions are normal.

If results imply large balance due, adjust withholding or estimated payments before December 31 when possible—penalties accrue on underpayment even when you file timely in April. If results imply large refund, you may be over-withholding or overpaying estimates; tune W-4 or voucher amounts for better cash flow without chasing refunds as a savings strategy.

State returns often piggyback federal logic but diverge on conformity items. Re-run state tools when federal inputs change materially so you do not pay state estimates based on federal-only planning from this foreign tax credit calculator page.
