How Do TN Visa Holders File U.S. Taxes?
TN visa holders from Canada and Mexico file U.S. taxes based on their residency status under the Substantial Presence Test, not their visa type. Unlike F-1 and J-1 visa holders, TN visa holders have no exempt days, so most pass the SPT and become U.S. resident aliens for tax purposes within their first calendar year (IRS: Determining Alien Tax Status).
TN visa tax residency timeline:
| Scenario | Tax Status | File |
| Arrived January 1, present 183+ days | Resident alien for full year | Form 1040, worldwide income |
| Arrived July 1, present under 183 days in year 1 | Nonresident alien year 1 | Form 1040-NR, U.S.-source income only |
| Present 183+ days using 3-year lookback | Resident alien | Form 1040, worldwide income |
| First-year choice election made | Resident alien from arrival date | Form 1040 with dual-status statement |
Key tax obligations for TN visa holders:
- Resident aliens report worldwide income on Form 1040, including Canadian or Mexican income earned before arriving
- No FICA exemption: unlike F-1 students, TN visa holders pay Social Security and Medicare tax from day one
- State taxes apply: you owe state income tax in the state where you work
- FBAR and Form 8938: if you maintain Canadian or Mexican bank accounts above the thresholds, you must report them
- Canadian RRSP/TFSA: may require U.S. reporting; RRSP is tax-deferred under the U.S.-Canada treaty if you file the proper election
Treaty benefits for TN visa holders:
- U.S.-Canada treaty: Article IV tiebreaker for dual residents; Article XVIII for pensions; Article XXIX(3) saving clause preserves U.S. taxing rights on citizens and residents
- U.S.-Mexico treaty: similar tiebreaker provisions; less favorable pension treatment than the Canada treaty
- Claim treaty positions on Form 8833 attached to your return
When your TN status ends (you leave the U.S.), you file a final U.S. return covering the period of residency. If you return to Canada or Mexico mid-year, the year of departure is a dual-status year.
