TN visa holders must still file a US tax return. If you are in the US for 183+ weighted days, you are treated as a US tax resident and must report worldwide income.
Even if you keep ties to Canada, you may still owe Canadian tax, but the Canada-US Tax Treaty helps prevent double taxation, though filings are still required in both countries.
The TN visa is a popular option for Canadian professionals working in the United States. Created under NAFTA and continued under USMCA, it allows Canadians to work in approved occupations without requiring employer sponsorship for a green card, making it attractive for both short- and long-term roles.
However, it also creates complex cross-border tax issues. TN visa holders may have filing obligations in both Canada and the US, depending on residency and income sources, which is why understanding TN visa tax rules is important when moving from Canada to the US.
Key Summary: TN Visa Tax
-
Canadians working in the US under a TN visa must understand TN visa tax rules, which often create filing requirements in both countries depending on residency status and income sources.
-
The tax implications of moving from Canada to the USA can include departure tax, dual reporting during the transition year, and potential worldwide income reporting if US residency is established.
-
Taxes for Canadians working in the US include federal income tax, state tax (in many states), and payroll taxes; most TN workers must pay Social Security tax unless exempt under the totalization agreement.
-
TN Visa workers must be classified as employees—not contractors—meaning that receiving a 1099 while on a TN visa violates immigration and tax rules and can jeopardize their status.
-
US employers have specific tax and withholding obligations for TN visa employees, including issuing W-2s, withholding payroll taxes, and ensuring the TN employee is working in an authorized, compliant role.

Eligibility for the TN Visa
To qualify for a TN visa, a Canadian must:
- Be a citizen of Canada (permanent residents are not eligible).
- Have a job offer from a US employer in a qualifying professional occupation (e.g., accountant, engineer, lawyer, medical professional, scientist, etc.).
- Possess the required educational credentials or professional licenses.
- Work in a role that is listed under the USMCA-approved professions.
The TN visa is typically granted for up to three years and can be renewed indefinitely provided the individual continues to meet the requirements.
Important TN visa rule: TN visa holders cannot be self-employed in the US. Their employment must remain tied to a sponsoring employer
TN Visa Tax Residency Considerations
One of the key factors that affects a TN visa holder’s tax situation is their tax residency status in both Canada and the United States. Unlike a work visa, which solely determines employment eligibility, tax residency determines where an individual must report and pay taxes.
US Residency Tax Rules
A Canadian on a TN visa may be considered a US tax resident if they meet the Substantial Presence Test (SPT). This test evaluates the number of days spent in the US over a three-year period, using the following formula:
- All days present in the current year
- 1/3 of the days in the previous year
- 1/6 of the days in the year before that
If the total equals or exceeds 183 days, you are treated as a US tax resident. You must file Form 1040 and report worldwide income, including Canadian employment income, rental income, and investment earnings.
If you do not meet the SPT, you are a nonresident alien and file Form 1040-NR, reporting only US-sourced income.
| Scenario | US Tax Status | Form to File |
| SPT met (183+ weighted days) | US Tax Resident | Form 1040 |
| SPT not met | Nonresident Alien | Form 1040-NR |
| First/last year in US | Dual-Status | Form 1040 + 1040-NR |
Canadian Tax Residency Rules
Canada determines tax residency based on residential ties, not physical presence. Even if you spend most of the year in the US, you may remain a Canadian tax resident if you maintain:
- A home available for use in Canada
- A spouse or common-law partner remaining in Canada
- Dependents still living in Canada
- Canadian bank accounts, driver’s licence, or provincial health insurance
If you sever your Canadian residential ties by establishing permanent US residency, you become a deemed non-resident. This triggers a Canadian departure tax on certain deemed dispositions of property and requires a final T1 General return covering the period of Canadian residency.
US Tax Obligations for TN Visa Holders
If a TN visa holder meets the substantial presence test and is classified as a US tax resident, they must:
- File a US tax return (Form 1040): Report worldwide income, including Canadian employment income, rental income, and investment earnings.
- Pay Social Security and Medicare taxes: Unlike other visa holders, TN visa workers are subject to payroll taxes in the US.
- Report foreign financial accounts: If the aggregate value of foreign accounts exceeds $10,000 at any time during the year, the individual must file a Foreign Bank Account Report (FBAR) with FinCEN.
- File Form 8938 (FATCA reporting): If foreign financial assets exceed certain thresholds, additional reporting may be required.
These obligations make TN visa tax filing in the US more complex than simply reporting salary.
If the individual does not meet the substantial presence test, they can be classified as a nonresident alien and file Form 1040-NR, which generally requires reporting only US-sourced income.

Canadian Tax Obligations for TN Visa Holders
If a TN visa holder remains a Canadian tax resident, they must:
- File a Canadian tax return (T1 General): Report worldwide income, including US wages, rental income, and business profits.
- Pay Canadian tax on foreign income: Canada taxes worldwide income, but foreign tax credits can help offset double taxation.
- Report foreign property: If the value of foreign investments exceeds CAD 100,000, individuals must file Form T1135 (Foreign Income Verification Statement).
For those who become deemed non-residents, they must still file a Canadian return for any income earned in Canada but are otherwise exempt from reporting worldwide income.
Canada-US Tax Treaty: Avoiding Double Taxation
The Canada-US Tax Treaty plays a key role in handling TN visa tax obligations. It helps prevent double taxation by outlining which country has the primary right to tax specific types of income and providing tax credits.
- Foreign Tax Credits: TN visa holders can claim a foreign tax credit on their Canadian return for US taxes paid, and vice versa if they are US tax residents.
- Tie-Breaker Rules: If residency is disputed, the treaty has a series of tests to determine primary tax residency, considering permanent home location, center of vital interests, habitual abode, and nationality.
- Pension and retirement income:The treaty contains specific provisions for 401(k)s, RRSPs, CPP, and OAS that affect how retirement accounts are treated across the border.
- Employment income sourcing: Income is generally taxed where the work is performed, which is the US for most TN visa holders.
Canadian Departure Tax: What Happens When You Leave
When a Canadian permanently relocates to the US and severs Canadian residency, the CRA treats it as a deemed disposition of most capital property at fair market value on the date of departure. This can trigger a capital gains tax liability — the departure tax — even if you have not actually sold anything.
Assets commonly affected include:
- Canadian investment accounts (non-registered)
- Shares in private corporations
- Foreign property, including US real estate purchased before departure
Certain assets are exempt, including your principal residence, RRSPs, RRIFs, and Canadian real estate. Proper timing and advance planning can significantly reduce departure tax exposure.
TN Visa and Self-Employment: Why a 1099 Violates Your Status
A TN visa strictly requires W-2 employment with a US employer. You cannot be self-employed, operate your own business, or work as an independent contractor.
- You must receive a W-2, not a Form 1099. If a US company pays you as a contractor and issues a 1099, this violates TN visa rules — regardless of how the work is structured.
- You cannot actively run a US business. TN visa holders may invest in a business passively but cannot manage or operate it.
- Misclassification is an immigration risk. Being paid on a 1099 while on a TN visa can jeopardize your status and trigger both tax and immigration consequences.
Employers hiring TN visa workers must classify them as employees, withhold federal and state income taxes and FICA, and issue a W-2 at year-end.
Starting a Business in the US on a TN Visa
A TN visa does not permit self-employment or active business ownership. TN holders can make passive investments in a US business but cannot manage or operate one. Independent contracting is also prohibited, and receiving a 1099 violates TN status regardless of how the arrangement is structured
If you want to start or actively run a US business while on a TN visa, you would need to transition to a different visa category — such as an E-2 investor visa — that permits entrepreneurship.

Investing in US Real Estate on a TN Visa
TN visa holders can purchase US property for personal use or rental investment. Key tax considerations:
- Rental income — Taxable in the US. If you remain a Canadian resident, Canada may also tax it, though foreign tax credits offset double taxation.
- Capital gains on sale — Taxable in the US. If you are a nonresident alien, FIRPTA requires the buyer to withhold 15% of the sale price — this is a prepayment toward your tax liability, not an extra tax.
- Canadian departure tax — US real estate purchased before severing Canadian residency may be subject to deemed disposition on your departure date.
Retirement Accounts for TN Visa Holders: 401(k) and RRSP
- 401(k) and US retirement accounts — TN workers are typically eligible to contribute to employer-sponsored 401(k) plans. Contributions reduce US taxable income and grow tax-deferred. The Canada-US Tax Treaty allows Canada to recognize the 401(k) as a tax-deferred account, so you are not taxed in Canada on the growth while it remains in the plan.
- RRSP while on TN visa — If you retain Canadian residency, you can continue contributing to your RRSP based on available room from prior Canadian earned income. If you sever Canadian residency, contributions stop but the account remains open and continues to grow tax-deferred. The treaty allows the US to also recognize the RRSP as deferred, avoiding immediate US tax on the growth inside it.
- CPP and OAS — Canadians who contributed to CPP while working in Canada remain entitled to those benefits regardless of TN visa status. The Canada-US Tax Treaty governs how CPP and OAS payments are taxed once received.
TN Visa Tax Benefits
While most discussions focus on obligations, there are also several TN visa tax benefits that Canadians should be aware of:
-
Foreign Earned Income Exclusion (FEIE): If you qualify under certain conditions, you may be able to exclude a portion of your US income from US taxation when filing from abroad.
-
Foreign Tax Credits: Canadians on TN visas who remain Canadian tax residents can often offset Canadian tax with credits for US tax paid, reducing the chance of double taxation.
-
Deductible Moving Expenses: In some cases, cross-border moves for employment under a TN visa may allow certain deductions.
-
Treaty-Based Exemptions: The Canada-US Tax Treaty provides exemptions for specific income types, such as pensions or government benefits, which can lower overall tax liability.
-
Retirement Account Opportunities: Working in the US allows TN visa holders to contribute to US retirement plans (such as 401(k)s), which may offer tax deferral benefits in both countries.
These TN visa tax benefits demonstrate that with proper planning, working in the US can provide not only professional opportunities but also potential financial advantages.
