What is Form 1116?
Form 1116 calculates the Foreign Tax Credit, which prevents double taxation on income earned abroad. The credit equals the lesser of foreign taxes actually paid or the US tax attributable to foreign-source income (US tax x foreign income / worldwide income). This limitation ensures foreign taxes cannot offset US tax on domestic income.

How PaisaTax Handles It
- Foreign taxes sourced from 1099-DIV Box 7, 1099-INT Box 6, and manual entries
- Limitation formula computed as US tax liability x (foreign income / worldwide income)
- Credit equals the lesser of taxes paid or the computed limitation
- Excess credits may carry forward to future tax years (not yet automated)
Common Situations
- Mutual fund foreign taxes: 1099-DIV Box 7 shows $200 foreign tax paid on international fund dividends.
- Limitation binding: $500 foreign taxes paid but limitation is $350 — credit is $350, $150 excess carries forward.
- Small amounts: If total foreign taxes are $300 or less ($600 MFJ), taxpayers may elect to skip Form 1116 and claim the credit directly.
