The number that decides your taxes, your health coverage, and your insurance.
Get a QuoteIf you spend winters south of the border, the 182-day rule is the single most important number in your financial life. It determines your tax residency, your provincial health coverage, and — by extension — what your travel insurance needs to do.
If you're in the US for more than 182 days in any 12-month period, the IRS can classify you as a US resident for tax purposes under the Substantial Presence Test. Canada has its own residency tests. The result: you could face tax obligations in both countries if you don't track your days carefully.
Most provinces require you to be physically present for at least 153 days (about 5 months) in a 12-month period to maintain residency. If you're gone too long, you lose your provincial health coverage — and many travel insurance policies require you to have it.
Most Canadian travel insurance assumes you have valid provincial health coverage. If you lose it by exceeding the residency threshold, your travel insurance may not coordinate benefits the way you expect — and you could face higher out-of-pocket costs or denied claims.
Keep a log. Count every day you're in the US, including partial days. The 12-month rolling window means it's not just a calendar year — it's any 12-month period. A cross-border tax advisor can help if you're near the limit.
