US taxes for Americans in Canada

Front-loaded answerCanada taxes residents on worldwide income at high combined federal-and-provincial rates, and you still file a US return every year. But the US–Canada treaty and the totalization agreement are among the most robust anywhere — between the Foreign Tax Credit and treaty relief, most Americans owe little or no extra US tax, though the paperwork is real.

Treaty, totalization & the Foreign Tax Credit

Because Canadian tax usually equals or exceeds US tax on the same income, the Foreign Tax Credit (Form 1116) typically eliminates your US liability — the FEIE matters less here than in low-tax countries. The treaty adds residency tie-breakers and reduced withholding, and the totalization agreement coordinates US Social Security with the Canada Pension Plan so you don't pay into both on the same earnings.

FBAR, FATCA & Canadian account traps

Canadian bank and investment accounts trigger the usual US disclosures — and some popular Canadian registered accounts are US-reporting headaches. TFSAs and RESPs often aren't treated as tax-favored by the IRS (and can be foreign trusts), while RRSPs are protected by the treaty. Get a cross-border preparer before opening them.

Frequently asked

Will I pay more tax in Canada than in the US?

Possibly on the Canadian side — combined federal and provincial rates can exceed 50% at high incomes. But the Foreign Tax Credit usually credits that Canadian tax against your US bill, so you rarely owe extra US tax. The bigger cost is complexity, not double taxation.
