Do US citizens living in Canada still have to file US taxes?

Yes. A US citizen living in Canada generally still has to file a US tax return, even if they already pay Canadian taxes.

The US uses citizenship-based taxation, so your filing obligation follows you wherever you live. Canada, by contrast, taxes based on residency, meaning if you are a Canadian tax resident, you generally report worldwide income there as well.

In practice, this often leads to dual filing:

A US return reporting global income
A Canadian return based on residency

Who actually needs to file US taxes?

You generally need to file a US tax return if your income exceeds IRS thresholds, even while living in Canada.

For the 2025 tax year (filed in 2026), common filing thresholds are:

Single: US$15,750
Married filing jointly: US$31,500
Head of household: US$23,625

Note: These amounts are adjusted each year for inflation, so they may change in future tax years.

Even if your income is below these thresholds, you may still need to file if:

You want to claim a refund
You need to report foreign accounts
You are using provisions like the FEIE

How does Canada tax Americans who live there?

Canada taxes individuals based on residency status. If you are a resident, you generally report worldwide income. If you are a non-resident, Canada typically taxes certain Canadian-source income. Here’s a quick comparison of how the systems differ:

US vs Canada tax system: key differences for expats

Topic	United States	Canada
Main basis for taxation	Citizenship	Residency
Worldwide income taxed	Yes (for citizens)	Yes (for residents)
Filing trigger	Citizenship-based	Residency-based

How do you avoid double taxation between the US and Canada?

Many Americans in Canada reduce or avoid double taxation through the Foreign Tax Credit, and in some cases, the FEIE or treaty-based rules.

The Foreign Tax Credit allows you to offset US tax using Canadian taxes already paid.
If you qualify, the Foreign Earned Income Exclusion can exclude up to US$130,000 of 2025 earned income per person.
You cannot use both methods on the same income. However, some taxpayers use them across different income types.
The Foreign Earned Income Exclusion (FEIE) applies only to earned income, such as wages or self-employment income. The Foreign Tax Credit (FTC) applies to both earned and passive income, including dividends and interest.

Is the Foreign Tax Credit or FEIE better for Americans in Canada?

In many Canada-based situations, the Foreign Tax Credit is often more effective, but the better option depends on your income and tax position. Here’s a side-by-side comparison:

Foreign Tax Credit vs FEIE: which is better for Americans in Canada?

Feature	Foreign Tax Credit	FEIE
Function	Offsets US tax	Excludes earned income
Works well in Canada	Often	Sometimes
Covers investment income	Yes	No
Carryover option	Yes	No

What tax forms might a US citizen in Canada need to file?

Most Americans in Canada file Form 1040, and may also need additional forms depending on their situation. The key is to identify your income, account balances, and residency details first, then match them to the forms that apply. Here’s a simplified overview:

Common US tax forms for Americans living in Canada

Form	Purpose	When it applies
Form 1040	Main US tax return	Filing requirement met
Form 1116	Foreign Tax Credit	Foreign tax paid
Form 2555	FEIE	Earned income exclusion
FBAR (FinCEN Form 114)	Foreign account reporting	Over $10,000 combined
Form 8938	Foreign asset reporting	Higher thresholds apply

Do you need to report Canadian bank accounts and assets?

Yes, in some cases. If your total foreign account balances exceed US$10,000 at any point during the year, you may need to file an FBAR. Here’s how the reporting rules generally work:

FBAR (FinCEN Form 114): Required if foreign accounts exceed US$10,000 combined; Filed separately from your tax return
Form 8938 (FATCA): Applies at higher asset thresholds; Filed with your US return
Important distinction: FBAR and FATCA are separate; You may need one, both, or neither

What should self-employed Americans in Canada know?

Self-employed Americans in Canada generally pay social security-type taxes to only one country under the US-Canada Totalization Agreement, although the outcome depends on the specific situation. In many cases, a certificate of coverage is required to confirm which country’s system applies.

How are RRSPs, RRIFs, and TFSAs treated for US taxes?

RRSPs and RRIFs receive favorable treatment under IRS guidance, while TFSAs do not have the same clear treatment and may create US tax or reporting complexity.

For RRSPs and RRIFs:

Forms 3520 and 3520-A are generally not required
Treaty provisions may allow tax deferral under Article XVIII(7) of the US–Canada tax treaty
No election is required following Rev. Proc. 2014-55

For TFSAs:

Income may still be taxable in the US
Reporting depends on the account structure and underlying investments
Some may be treated as foreign grantor trusts, while others may require Form 8621 if investments are classified as PFICs
