The Definitive Guide to U.S. Taxes for Canadian Nurses on a TN Visa (2026)
Published January 2026 | Updated with current cross-border tax guidance
Working in the United States as a Canadian registered nurse under a TN visa opens doors to exciting career opportunities and often higher income, but cross-border taxation can feel overwhelming if you’re not prepared. This guide breaks down exactly where you pay tax, how to avoid double taxation, and what to expect on your paycheck and at tax time — with key details that matter to nurses planning a move.
1. You Always File a U.S. Tax Return on U.S. Earnings
This applies even if you are physically working full-time in the United States.
If you work in the U.S. and earn income here, you’re required to file a U.S. income tax return — no exceptions. For most TN nurses:
-
Many Canadian TN visa nurses initially file Form 1040-NR as nonresident aliens for U.S. tax purposes.
-
If you meet the Substantial Presence Test (based on days in U.S. over 3 years), the IRS could treat you as a U.S. tax resident and require a regular Form 1040 instead.
-
Your employer withholds U.S. federal income tax and often state income tax from your paycheck.
Why it matters: Your U.S. tax obligation is tied to where the income is earned, not your visa category. Even on a temporary TN visa, U.S. wages are taxed here.
2. You’re Still Connected to Canada Unless You Sever All Ties
Canada decides tax residency based on your life ties, not your visa:
A. You Keep Strong Connections/Ties to Canada
If you have:
-
A home in Canada
-
A spouse or dependents in Canada
-
Canadian bank accounts
-
Provincial health coverage
Then Canada likely considers you a tax resident — and you must:
-
File a Canadian tax return (T1)
-
Report worldwide income, including U.S. wages
-
Claim a foreign tax credit for U.S. taxes paid so you aren’t taxed twice
This is completely normal for nurses in their first years working in the U.S.
B. You Sever Canadian Residential Ties
If you truly relocate (sell your house, end provincial coverage, move your family), Canada may consider you a non-resident for tax purposes. In that case:
-
You would not file a standard Canadian return
-
You only pay Canadian tax on Canadian-source income (like rent or investments)
⚠️ Important: Tax residency is a legal determination — consult a cross-border tax expert before assuming a change.
3. How the U.S.–Canada Tax Treaty Helps You Avoid Double Taxation
The U.S. and Canada have a comprehensive tax treaty that prevents double taxation — meaning you shouldn’t pay tax on the same income in both countries without relief.
The key mechanism most Canadian TN visa holders use is the foreign tax credit on your Canadian tax return for taxes already paid to the U.S. This helps ensure the money you earn isn’t taxed twice.
4. Payroll Taxes: Social Security & Medicare — What to Expect
Unlike some visa categories that may exempt Social Security/Medicare withholding, Canadian TN workers are generally subject to U.S. Social Security and Medicare (FICA) taxes from day one, depending on their individual circumstances.
-
Your employer will typically withhold FICA taxes (Social Security and Medicare) from your pay.
-
There is a Totalization Agreement between the U.S. and Canada to avoid double contributions, but it doesn’t automatically exempt taxes — proper setup and interpretation are required.
Bottom line: Expect FICA withholding unless a specialist determines an exemption applies.
5. What Your Paycheck Actually Looks Like
When discussing U.S. offers, nurses are quoted gross pay — the full hourly or salary amount before deductions. After withholding for:
-
Federal and possibly state income tax
-
Social Security & Medicare
-
Any benefits you elect
Your net take-home pay may look significantly lower than the headline figure — so budgeting requires looking at numbers after tax.
6. Things Canadian Nurses Often Overlook
Here are a few cross-border nuances that can catch people off guard:
Tax Residency Can Flip: Spending enough days in the U.S. triggers U.S. tax residency even if you keep Canadian residency.
State Taxes Vary Widely: Some U.S. states have no income tax, while others may significantly affect net pay.
Bank Reporting: Foreign bank accounts over certain thresholds may trigger additional U.S. reporting requirements.
Professional Advice Is Worth It: Cross-border tax law is granular — professional guidance can save headaches and money.
Final Takeaway
For Canadian nurses on a TN visa:
✔ You will file a U.S. tax return on your U.S. income.
✔ You may still be a Canadian tax resident and file there too.
✔ The U.S.–Canada tax treaty helps prevent double taxation.
✔ Paychecks reflect mandatory withholding before you receive your net income.
✔ Getting expert tax planning is one of the smartest moves you can make before your first U.S. tax-filing season.
