Capital gains tax by province — why the same sale costs different amounts

The 50% inclusion rate is federal and identical from Victoria to St. John's. What differs is what happens next: the taxable half is added to your income and taxed at your combined federal and provincial marginal rate, and the provincial half of that spans more than twenty points. Take one seller with C$90,000 of other taxable income and a C$350,000 gain on a rental, 2025 tax year, all figures in Canadian dollars:

• Ontario — C$79,237 of tax, a combined 45.3% on the taxable half. C$11,209 of that is Ontario surtax alone.
• Alberta — C$68,057 of tax, a combined 38.9%. No provincial surtax.

C$11,181 of difference on an identical sale, and a national average rate would have missed all of it. Ontario is the reason a bracket table alone is not enough: its surtax is charged on tax payable, not on income — 20% of Ontario tax above C$5,710 plus a further 36% above C$7,307, stacking to a 56% uplift. Quebec needs its own handling too, in the opposite direction: Quebec residents pay 16.5% less basic federal tax under the federal abatement. The calculator applies both mechanically rather than hard-coding a headline rate. The province that counts is where you were resident on 31 December of the year you sold, not where the property sits.

Quebec: the welcome tax is a different tax, and it is not on this page

Quebec's droit de mutation immobilière — the welcome tax, taxe de bienvenue — is searched for alongside capital gains tax and is routinely confused with it. They are opposites, and neither is a component of the other. The welcome tax is a municipal tax the buyer pays once at purchase on the property's transfer value, with nothing to do with profit. Capital gains tax is a federal and provincial income tax the seller pays on profit at disposition. If you are selling a Quebec property you owe the tax this page calculates and no welcome tax; your buyer owes the welcome tax and no capital gains tax. No welcome-tax figure appears in any total on this page.

The principal residence exemption isn't automatic — and a rental's ACB isn't the whole story

Claiming the exemption: Schedule 3 and Form T2091(IND)

A fully exempt principal residence still has to be reported. CRA requires the sale on Schedule 3 of your T1 return plus Form T2091(IND), Designation of a Property as a Principal Residence by an Individual, for the year you sold — a requirement in force since the 2016 tax year. Skip the form and CRA can assess a late-filing penalty even though no tax is owed. If the property was your principal residence for only some of the years you owned it, the exempt share is not eyeballed: it's (years designated + 1) ÷ total years owned of the gain, applied to whatever years it was your home rather than a rental or secondary property.

Selling a Canadian rental: adjusted cost base doesn't include CCA recapture

This calculator builds ACB the way CRA defines it — purchase price plus purchase closing costs plus capital improvements, never routine repairs — and applies the 50% inclusion rate to what's left after that. What it deliberately does not compute: if you claimed capital cost allowance (CCA) against this rental in any year you owned it, CRA requires the recapture added back to your income in the year of sale — calculated separately from the capital gain, fully taxable at 100% rather than the 50% inclusion rate, and driven by your undepreciated capital cost history, not by ACB. A depreciated rental owes more at disposition than this page's capital-gains figure alone shows. That number depends on your CCA claims across every year you owned the property, so it is deliberately left for a tax preparer with your T776 history rather than estimated here.

Turning a principal residence into a rental (or back) is itself a taxable event

This calculator, like most, prices a single sale on a single date. CRA does not see it that way when the property's use changes before that sale. Moving out of your home and renting it out — or moving into a former rental — is a change of use, and CRA treats the change itself as a deemed disposition: you are considered to have sold the property at its fair market value on the date the use changed and immediately reacquired it at that same value, whether or not any money changed hands. Any gain attributable to years the property genuinely was your principal residence stays exempt; the deemed-disposition gain is calculated only on the change itself.

Two elections can defer that deemed gain rather than trigger it immediately:

• Subsection 45(2) — principal residence becoming a rental. Filing this election (a signed letter attached to your return, naming subsection 45(2) and describing the property) means you report no capital gain in the year you start renting it out, and CRA will still let you designate the property as your principal residence for up to four more years while it earns rental income — extended indefinitely if your employer relocates you at least 40 km away and specific conditions are met. The election is void if you claim capital cost allowance on the property in any year it is in effect, and you cannot designate any other property as your principal residence during the deferral period.
• Subsection 45(3) — a rental or business property becoming your principal residence. This election postpones reporting the earlier deemed disposition until you actually sell, and lets you designate up to four years before you moved in as principal-residence years too — but it is not available at all if you or your spouse claimed CCA on the property in any year after 1984. The letter must reach CRA by the earlier of 90 days after CRA requests it or your filing deadline for the year you actually sell.

Neither election is modelled by this calculator — the fair-market-value figure the deemed disposition runs on is a valuation question specific to the change-of-use date, not an input this tool collects. If you have changed how a property is used at any point you owned it, the number above is your final-sale gain only, and a change-of-use gain (deferred or not) may sit alongside it.

How to calculate capital gains tax on an investment property in Canada

Four steps, in order — the same steps the calculator above runs, laid out so you can check it by hand:

1. Find the adjusted cost base (ACB) — purchase price, plus purchase-side closing costs (legal fees, land transfer tax, inspection), plus capital improvements. Routine repairs do not count.
2. Subtract ACB from the sale price — sale price minus selling costs (commission, legal fees) minus ACB = your capital gain.
3. Apply the 50% inclusion rate — only half of the gain is taxable income. A C$350,000 gain adds C$175,000 to your taxable income for the year.
4. Tax the taxable half at your combined marginal rate — federal bracket plus your province's bracket (plus Ontario's surtax on tax payable, where it applies), at the rate your other income already has you in.

Worked for an investment property in Ontario: a seller with C$90,000 of other taxable income and a C$350,000 gain on a rental owes C$79,237 in combined federal and Ontario tax — a 45.3% rate on the taxable half, C$11,209 of which is Ontario’s surtax on tax payable, not on income. The same investment property owned by an Alberta resident with identical numbers owes C$68,057 — no province-level surtax applies there.
