US Tax Guide for Dual Citizens Living in Canada

Dual citizens (US + Canada) face unique US tax challenges. As US citizens, they owe US tax on worldwide income regardless of where they live. Canada's worldwide income taxation and the US-Canada tax treaty create additional complexity. FileAbroad helps dual citizens in Canada navigate FEIE, FBAR, and the cross-border questions that complicate filing.

Key Tax Issues for Dual Citizens in Canada

• Worldwide US taxation: US citizens owe US tax on worldwide income, even if they live in Canada and are Canadian citizens.
• Canadian tax residency: If you establish significant residential ties in Canada, you are a Canadian tax resident. You may owe tax to both countries.
• FEIE: Dual citizens can claim FEIE on foreign earned income if they have a foreign tax home and meet the physical presence or bona fide residence test.
• FTC: Dual citizens can claim FTC for Canadian tax paid on income that is also taxed by the US.
• RRSP/TFSA: RRSP contributions may be deductible on your US return (unique treaty benefit). TFSA is NOT tax-free in the US.
• Totalization agreement: US-Canada totalization agreement prevents double social security taxation.

FEIE vs FTC for Dual Citizens in Canada

FTC is often more valuable than FEIE due to high Canadian tax rates (up to 53.53%). FEIE may be better for dual citizens in their first years abroad or with income below the FEIE limit.

FBAR & Reporting for Dual Citizens in Canada

Canadian bank accounts, RRSPs, TFSAs, and RESPs are reportable on FBAR if the aggregate value across all foreign accounts exceeds $10,000. Dual citizens often have accounts in both the US and Canada.

Common Mistakes Dual Citizens Make in Canada

1. Not filing US tax returns — US citizens owe US tax on worldwide income regardless of where they live.
2. Not reporting Canadian accounts, RRSPs, and TFSAs on FBAR — All foreign accounts are reportable.
3. Not understanding RRSP/TFSA US tax treatment — RRSP may be deductible; TFSA is not tax-free.
4. Not claiming FEIE or FTC — These tools can significantly reduce your US tax.

When to Get Professional Help

You should consider professional help if you have foreign accounts exceeding $10,000, complex income situations, or questions about RRSP/TFSA reporting.
