Do US Citizens Living in Canada Have to File US Taxes?
Yes — and this surprises many Americans who move abroad. The United States is one of only two countries in the world that taxes based on citizenship rather than residency. This means that as a US citizen living abroad, you are legally required to file a US federal tax return every single year, reporting your worldwide income to the IRS.
This obligation applies whether you live in Canada, the UK, Australia, Germany, or anywhere else. It applies even if you have no US-source income, even if you already pay taxes locally, and even if you've lived abroad for decades.
For US taxes in Canada specifically, the obligation is even more nuanced because of the Canada-US Tax Treaty, Canadian retirement accounts like RRSPs and TFSAs that the IRS treats differently from the CRA, and the interplay between Canadian and US tax rates.
If you are not a US person but a Canadian resident with US income or property, that is a different profile — see our page for Canadian residents with US tax exposure.
IRS Requirements for US Citizens Abroad
IRS compliance for US citizens abroad extends well beyond a standard tax return. Depending on your situation, you may be required to file multiple forms each year:
Annual US individual tax return — required even with zero US income
Required when foreign accounts exceed $10,000 in aggregate at any point in the year
Reports foreign financial assets above certain thresholds to the IRS
Foreign Earned Income Exclusion — can exclude up to $126,500+ from US tax
Foreign Tax Credit — offsets US tax with foreign taxes already paid
Treaty-based position elections under applicable US tax treaties
Missing any of these forms — even inadvertently — can trigger IRS penalties. Our team reviews your full financial profile to ensure every required form is filed accurately and on time.
Common Mistakes US Expats Make
Many US expats make costly errors that can result in significant penalties and back taxes. Here are the most frequent issues we encounter:
Not filing at all
Assuming that living abroad exempts you from US taxes is the most dangerous mistake. The IRS can pursue non-filers indefinitely, and penalties compound each year.
Missing FBAR deadlines
FBAR is due April 15 with an automatic extension to October 15. Willful failure to file carries penalties up to $100,000 or 50% of account value per violation.
Mishandling Canadian accounts (RRSPs, TFSAs)
RRSPs require a treaty election; TFSAs are not tax-sheltered for US purposes and generate taxable income. Failing to address these correctly is extremely common among US citizens in Canada.
Not using the Foreign Tax Credit properly
Many expats pay more US tax than necessary because they don't correctly apply Foreign Tax Credits or claim treaty benefits.
Using a domestic US tax preparer
General US tax preparers often lack knowledge of expat-specific forms, treaty provisions, and FBAR requirements. Specialized expertise is essential.
How to Avoid Double Taxation as a US Expat
Most US expats do not end up paying taxes twice on the same income — but this requires proper use of available mechanisms. The three main tools are:
Foreign Tax Credit (Form 1116)
Allows you to offset US tax dollar-for-dollar with foreign taxes paid. For US citizens in Canada, where tax rates are generally higher than US rates, this often results in little to no additional US tax owed.
Foreign Earned Income Exclusion (Form 2555)
Allows qualifying expats to exclude earned income (salary, self-employment) up to $126,500 (2024) from US taxation. Works best for expats in lower-tax countries. Cannot be combined with the Foreign Tax Credit on the same income.
Tax Treaty Benefits
The US has tax treaties with over 60 countries. For US citizen tax filing in Canada, the treaty provides rules for pensions, real estate, business income, and other income types. Certain elections must be made formally on your US return to receive treaty protection.
Our advisors analyze your complete situation to determine the optimal combination of these tools — there is no one-size-fits-all approach.
