Answer the questions below. The result is a likely outcome only, based on the CRA residential ties approach and the IRS substantial presence test. Cross-border cases need review, and I prepare both Canadian and US returns.
How it works
- Canada: a home, spouse or partner, or dependants in Canada are significant residential ties. Without them, 183 or more days can make you a deemed resident.
- US: citizens and green card holders are US residents for tax. Others are tested on days: at least 31 this year and 183 weighted days (this year, plus one third of last year, plus one sixth of the year before).
- If both countries could treat you as resident, the treaty tie-breaker looks at permanent home, then centre of vital interests, then habitual abode, then citizenship.
