When you stop being a Canadian tax resident, the CRA treats most of your property as sold at fair market value on the day you leave, and taxes the gain. This calculator estimates that bill, shows which assets are excluded, and flags the forms your file would need. It's an estimate for planning, not tax advice for your specific situation.
Every dollar box below takes up to $100,000,000. A larger entry is pulled back to that, and the estimate says so when it happens.
Assumptions this estimate makes: a single combined federal-plus-provincial rate that you selected; the current one-half capital gains inclusion rate; gains computed only on what you enter, with losses and gains netted against each other the way s. 3(b) nets them. It ignores provincial departure quirks, the US side of a move (including the treaty election that can reset your US cost basis), currency conversion, and any loss carried in from another year. Note on the $25,000 reporting test: foreign bank accounts and most other property also count toward Form T1161 even though this tool doesn't ask about them, so treat a missing T1161 flag as "maybe", not "no". A real departure file prices all of this properly.
The leaving-Canada tax checklist: the sequence, the forms, and the deadlines that go with the number above.
This tool provides general information and rough estimates only, not tax advice for your situation. Methodology checked against the statutes linked above; figures current to the 2026 filing year.
The Cross-Border Assessment is a fixed $250. You get a written, CPA-prepared read of your departure year, both sides of the border, before you commit to anything bigger.
