I live in Canada but work remotely for a US employer — where do I pay tax?
You pay tax in Canada. As a Canadian tax resident you are taxed on your worldwide income, and the US generally does not tax wages earned for services performed entirely outside the United States by a nonresident alien. In practice the tax answer is simple — the payroll setup is where most people get into trouble.
Why Canada taxes the income
Canada taxes its residents on worldwide income from all sources (Income Tax Act, s.2(1)). If you live in Canada and do the work from your home in Toronto or Vancouver, the salary is Canadian-source employment income in CRA's eyes, even though the employer sits in Texas. You report it on your T1 and pay federal and provincial tax at normal rates.
What the US does — and doesn't — do
The IRS position is clear: wages earned by a nonresident alien for services performed outside the United States are foreign-source income and are not subject to US federal income tax reporting or withholding (IRS Publication 519). So a Canadian resident with no US workdays should not owe US income tax on the salary at all.
The catch is administrative. Many US employers' payroll systems default to treating every employee as US-based:
- They may withhold US federal (and state) tax from your paycheques even though no US tax is due.
- They may issue you a W-2, which complicates your Canadian filing.
- They may not register for Canadian payroll (CRA payroll account, CPP/QPP and EI), leaving you exposed.
The clean setups, in order of preference: (1) the US employer registers a Canadian payroll or uses an employer-of-record (EOR) service; (2) you work as an independent contractor and invoice them (then you handle your own instalments and GST/HST considerations); (3) you remain a US-payroll employee and sort it out at filing time — the messiest option.
If both countries claim you: the treaty tie-breaker
If there is ever a dispute about where you are resident, the Canada-US treaty (Article IV) settles it with a sequential five-step test — you stop at the first step that gives a single answer:
| Step | Test |
|---|---|
| 1 | Where is your permanent home? |
| 2 | Where is your centre of vital interests (family, economic ties)? |
| 3 | Where is your habitual abode? |
| 4 | What is your nationality? |
| 5 | Mutual agreement between the two tax authorities |
For someone living full-time in Canada, the answer is almost always Canada at step 1 or 2.
Frequently asked questions
Do I still need to file a US tax return?
Generally no, if you are a nonresident alien with no US-source income. But if your employer withheld US tax or issued a W-2, you may need to file a 1040-NR to claim a refund of tax that should never have been withheld.
What if US tax was already withheld from my pay?
You can generally recover it by filing a US nonresident return claiming a refund. Longer term, give your employer a completed Form W-8BEN so their system stops withholding — and push for a proper Canadian payroll arrangement.
Does the treaty eliminate double tax if both countries tax me?
Yes — Article XXIV provides relief. Canada gives a foreign tax credit (Form T2209) for US tax paid, and the US gives a credit (Form 1116) for Canadian tax paid. The treaty prevents double taxation; it does not prevent double filing.
