Form 1116
Foreign Tax Credit (Individual, Estate, or Trust)
Form 1116 is the IRS form US persons use to claim a foreign tax credit for foreign income tax paid — preventing double taxation on the same income. For US persons with Canadian rental income (Americans living in Canada, dual citizens, green card holders), Form 1116 claims credit for the Canadian tax paid on Canadian- source rental income, capped at the US tax that would have been owed on the same income.

US persons (citizens, green card holders, US tax residents) who paid foreign income tax on foreign-source income — including Americans with Canadian rental property and dual citizens
Key Takeaways
- Form 1116 claims a foreign tax credit on the US return for foreign income tax paid — preventing double taxation up to the higher-jurisdiction tax rate.
- Credit is the LESSER OF (a) foreign tax actually paid, or (b) US tax that would have been owed on the same income. Excess foreign tax doesn't reduce US tax below the FTC limit.
- Computed per income category — rental income falls under 'passive category income'. Each category has its own limitation calculation.
- Simplified election (Section 904(j)) lets US persons with $300/$600 of total foreign tax skip Form 1116 and claim the credit directly on Form 1040. Most landlords exceed the limit.
- Unused FTC carries BACK 1 year and FORWARD 10 years — meaningful flexibility if foreign or US income fluctuates year over year.
What is the foreign tax credit?
US tax law taxes US persons on worldwide income, including foreign-source rental income. The Foreign Tax Credit (FTC) via Form 1116 prevents the same dollar from being taxed twice when foreign tax has already been paid on the same income.
For a US person with Canadian rental property:
- File Canadian return (Section 216 for non-resident owners, or T1 if Canadian resident). Pay Canadian tax on net rental income.
- File US Form 1040 reporting the same Canadian rental income on Schedule E (converted to USD).
- Claim Foreign Tax Credit on Form 1116, supported by proof of Canadian tax paid.
- FTC reduces US tax owed dollar-for-dollar, capped at the US tax that would have applied to the same income.
The FTC limitation
The credit is calculated per income category (passive, general, etc.). Rental income is typically passive category. The limitation for each category:
FTC limit = (foreign source income in category ÷ total taxable income) × US tax before FTC
Your actual credit is the lesser of:
- Foreign tax actually paid on the category income, OR
- The FTC limit (US tax allocable to that foreign income)
If US rate is lower than Canadian rate on rental income (common), foreign tax exceeds the limit and some Canadian tax is not fully credited in the current year. Excess carries back 1 year and forward 10 years.
If Canadian rate is lower than US rate (less common for rental income), full Canadian tax is credited and you pay top-up US tax on the residual.
Simplified election ($300 / $600 threshold)
IRC Section 904(j) simplified election lets US persons with total foreign tax of $300 or less ($600 for joint filers), all in passive category, skip Form 1116 and claim the credit directly on Form 1040 without the full limitation calculation.
For most landlords with Canadian rental property, the simplified election doesn't apply — Canadian tax on net rental income typically exceeds $300/$600. The simplified election is more relevant for small dividend-based foreign tax (a Canadian holding a US-listed ETF in a non-registered account, etc.).
Carryforward and carryback rules
Unused foreign tax credit (when foreign tax paid exceeds the FTC limit for the year) doesn't disappear:
- Carry back 1 year— amend the prior year's return to claim additional FTC there
- Carry forward 10 years — apply the excess in any of the next 10 tax years when FTC limit allows
- Carryforward / carryback must be in the same category (passive carries to passive only; general to general only)
For Canadian landlord with high Canadian tax in a year of low US income, excess Canadian tax credit carries forward to future years when US income (and US tax on that income) is higher.
Frequently asked questions
Who files Form 1116?
US persons (US citizens, green card holders, US tax residents) who paid foreign income tax. For Canadian-rental scenarios specifically: Americans with Canadian rental property, dual citizens with Canadian rental income, green card holders living in Canada with Canadian income. Canadian residents who are NOT US persons file Canadian Form T2209 instead (different form, same concept).
What's the simplified FTC election?
IRC Section 904(j) lets US persons with total foreign tax of $300 or less ($600 joint), all in passive category, skip Form 1116 and claim the credit directly on Form 1040. Most rental-income filers exceed the threshold — simplified election applies more to small dividend-based foreign tax.
What if my Canadian tax exceeds the FTC limit?
Excess foreign tax carries back 1 year and forward 10 years. Carryforward must stay in the same income category (passive to passive). Useful when foreign tax paid is higher than US tax on the same income in the current year, but expectations of higher US tax in future years.
What's the difference between Form 1116 (US) and Form T2209 (Canada)?
Form 1116 is the US-side foreign tax credit claim by US persons. Form T2209 is the Canadian-side equivalent claimed by Canadian residents. Both prevent double taxation on cross-border income but flow in opposite directions. A dual-jurisdiction filer (US person living in Canada with Canadian rental) may use Form 1116 (claim Canadian tax against US tax). A Canadian resident with US rental property uses T2209 (claim US tax against Canadian tax).
Do I need to convert foreign tax to USD?
Yes. Use the same exchange rate methodology you used for the foreign income — typically the Treasury yearly average for US persons converting CAD to USD. Apply consistently to both income and tax for the same year.
