Tax Obligations for Dual Citizens
This is the most complex aspect of dual citizenship. Here's what you need to know:
If You Live in Canada
- Canada: You are a Canadian tax resident and file Canadian taxes on your worldwide income
- US: You are still required to file US tax returns on your worldwide income (all US citizens must file, regardless of where they live)
- Tax Treaty: The US-Canada Tax Treaty prevents double taxation through foreign tax credits
- FBAR: You must report Canadian bank accounts over $10,000 USD to the US Treasury (FinCEN Form 114)
- FATCA: Canadian financial institutions report account information of US persons to the IRS
If You Live in the US
- US: You file US taxes normally as a US resident
- Canada: You are generally NOT a Canadian tax resident and do not file Canadian taxes (unless you have Canadian-source income like rental property)
Key Rule
You will almost never pay double tax thanks to the treaty. But the paperwork is real — budget $500–2,000/year for a cross-border tax specialist if you live in Canada with US citizenship.

Can my child be a dual US-Canadian citizen automatically?
If one parent is a US citizen and the other is Canadian, the child may be eligible for both citizenships at birth — regardless of where they're born. A child born in Canada gets Canadian citizenship automatically (jus soli). A child born to a US citizen abroad gets US citizenship if the parent lived in the US for 5+ years (2 after age 14). Register with both countries' consulates.
Do I have to tell the US government I became a Canadian citizen?
No. The US does not require you to report acquiring foreign citizenship. However, if you open Canadian bank accounts, you must report them via FBAR (FinCEN Form 114) if the total exceeds $10,000 at any point in the year. You should also continue filing US taxes annually.
