US citizens and resident aliens owe US income tax on worldwide income — including wages, dividends, and business income earned in other countries. But if you also paid income tax to a foreign government on that same income, the Foreign Tax Credit (FTC) lets you offset those foreign taxes dollar-for-dollar against your US tax bill, preventing double taxation. The credit is claimed on Form 1116 and can significantly reduce — or even eliminate — the US tax owed on foreign-source income. If your foreign taxes are modest and come solely from investment dividends, you may qualify for a simplified procedure without filing Form 1116 at all.

Quick answer: Paid income tax to another country? Claim the Foreign Tax Credit on Form 1116 to reduce your US tax dollar-for-dollar. Limit: can only credit up to the US tax on that foreign income. Two main baskets: passive (dividends/interest) and general (wages). Unused credits carry back 1 year, forward 10 years. Simplified method (no Form 1116): foreign taxes ≤$300 ($600 MFJ) from passive income only. Cannot credit taxes on FEIE-excluded income.

How the Foreign Tax Credit Works

The FTC is a dollar-for-dollar reduction in your US tax liability for qualifying foreign income taxes paid. It is not a deduction — it reduces your tax directly.

Example:

  • US taxpayer lives in Germany, earns $120,000 in wages
  • Pays $28,000 in German income tax
  • US tentative tax on that income (before credits): $22,000
  • Foreign Tax Credit: $22,000 (limited to US tax on the income)
  • US tax owed: $0
  • Unused German tax ($6,000) carries forward up to 10 years

What Taxes Qualify

To qualify, a foreign tax must be:

Requirement Details
A tax (not a fee or penalty) Must be an income, war profits, or excess profits tax
Paid or accrued You can claim on cash or accrual basis
Imposed on you (not refundable) Taxes your employer pays on your behalf may qualify; refundable credits do not
From a qualified country Most countries qualify; exceptions include countries under US sanctions (Iran, North Korea, etc.)

Common qualifying situations:

  • Withholding tax on foreign stock dividends (reported on 1099-DIV Box 7)
  • Income tax paid while working abroad on a foreign employer payroll
  • Tax on rental income from foreign property
  • Withholding on foreign bond interest

Do NOT qualify:

  • Value-added tax (VAT) or goods and services taxes
  • Social security taxes (usually covered by separate totalization agreements)
  • Taxes on income excluded under the Foreign Earned Income Exclusion (FEIE)
  • Taxes on tax-exempt income

The Foreign Tax Credit Limit and Baskets

The FTC cannot exceed what the US would have taxed on that same income. The limit is calculated separately for each income basket:

Basket What It Covers
Passive Dividends, interest, royalties, capital gains (most foreign investment income)
General Wages from foreign employment, active business income
Foreign Branch Income of a US person from a foreign branch
Section 901(j) Income from sanctioned countries (credits generally denied)

Why baskets matter: You cannot use excess credits from one basket to offset tax in another. If your foreign taxes on passive income exceed the limit for that basket, the excess carries forward — but it cannot be applied to general basket income.

Simplified Method: When You Can Skip Form 1116

If all of these apply, you can enter the credit directly on Schedule 3, line 1 without Form 1116:

  • All foreign income is passive (dividends, interest from foreign investments)
  • Total foreign taxes paid: $300 or less (single) or $600 or less (married filing jointly)
  • All foreign income and taxes are reported on a qualified payee statement (1099-DIV, 1099-INT, or similar)
  • You have no carryovers of unused foreign tax credits from prior years

This covers the common situation of US investors in international mutual funds or ETFs receiving foreign dividend withholding. Your brokerage reports the withholding in Box 7 of your 1099-DIV — you simply enter the total on Schedule 3.

Worked Example: International ETF Investor

Facts (Single taxpayer, $95,000 AGI):

  • Holds Vanguard Total International Stock ETF in taxable account
  • 1099-DIV shows: foreign dividends $4,200, foreign taxes withheld $420
  • All income is passive basket

Calculation:

  • US tax on the foreign dividends (assuming 15% qualified rate): $4,200 × 15% = $630
  • FTC limit: $630
  • Actual foreign taxes paid: $420
  • FTC claimed: $420 (full amount — below the limit)
  • Form 1116 required? No — $420 > $300 limit BUT exceeds individual threshold, so Form 1116 required (If it were $299 or less, no Form 1116 needed)

Tax savings: $420 reduction in US taxes owed — essentially recovering the foreign withholding.

Form 1116: Key Sections

Part What It Calculates
Part I Foreign country source income
Part II Foreign taxes paid or accrued
Part III Figuring the credit limit
Part IV Summary and carryovers

Complete a separate Form 1116 for each income basket. Most individual investors only need one Form 1116 for the passive basket.

Carryovers: Unused Credits

If your foreign taxes exceed the FTC limit in a given year:

  • Carry back: 1 prior tax year (amend that year’s return)
  • Carry forward: Up to 10 future tax years

Track carryovers carefully. Form 1116 Part IV shows the carryover amounts. Unused credits that are not used within 10 years are permanently lost.

FTC vs Foreign Earned Income Exclusion (FEIE)

US citizens living abroad often choose between:

  • FEIE (Form 2555): Excludes up to $126,500 (2024) of foreign earned income from US tax — but no FTC on the excluded portion
  • FTC (Form 1116): Credits foreign taxes paid against US tax — allows for larger retirement account contributions and Social Security credit

Many expats choose one or the other based on which produces a lower tax bill. In high-tax countries (Germany, France, UK), the FTC often eliminates US tax entirely. In low-tax countries, the FEIE may be more advantageous.

The Foreign Tax Credit is the primary tool for avoiding double taxation on foreign-source income. Most US investors with international stock funds qualify for a small FTC each year — and it is often one of the most overlooked tax credits on US returns.
