Canada Capital Gains Tax Calculator (2026)

Calculate the 2026 tax on a capital gain in any Canadian province or territory: 50% inclusion, federal and provincial brackets, with and without the gain.

Province or territory of residence

Proceeds of disposition (sale price) (C$)

Adjusted cost base (ACB) (C$)What you paid, including commissions and improvements, adjusted for return of capital

Outlays and expenses of the sale (C$)Selling commissions, legal fees, real-estate fees

Other 2026 taxable income (C$)Employment, pension, interest, rental and other income, after deductions such as RRSP

Other net-income amounts deducted only from taxable income (C$)Difference between your other net income (line 23600) and other taxable income. Exclude the gain and carryforward entered here. Do not add RRSP deductions: those already reduce net income.

Other capital losses this year (C$)Full loss amount from other sales in 2026

Eligible prior-year net capital losses to apply (C$)Taxable-loss amount already adjusted to the current 50% inclusion rate; not necessarily the raw notice-of-assessment balance. Pre-May-23-1985 special losses are excluded.

Estimate the change in regular 2026 Canadian income tax caused by an ordinary capital gain, using the 50% inclusion rate. The calculation compares federal and provincial tax before and after the gain, with basic personal credits only. It supports full-year residents; it does not determine alternative minimum tax, other credits, benefits or provincial low-income reductions.

How to use this tool

Choose your province or territory of residence on 31 December 2026.
Enter proceeds, adjusted cost base and selling expenses in Canadian dollars.
Enter other taxable income and any difference between other net income and taxable income.
Enter allowable current-year losses and eligible prior-year losses adjusted to the current inclusion rate.

Formula

Taxable gain = max(0, 50% × net gain − eligible prior losses); extra tax = tax with gain − tax without gain

Current-year capital losses offset gains before inclusion. Prior-year net capital losses reduce taxable income, but not net income used to phase out federal, Yukon and Manitoba basic personal amounts. Ontario includes surtax and its health premium; Quebec includes the 16.5% federal abatement. Manitoba’s statutory thresholds are $47,000 and $100,000. The next-$100 calculation also respects any remaining prior-year loss balance.

Example

An Ontario resident has $80,000 other taxable and net income, sells shares for $50,000 with $30,000 ACB, and has no losses. Half the $20,000 gain is taxable: $10,000 × (20.5% federal + 9.15% Ontario) = $2,965. No surtax changes and the health premium remains $750. Other credits and benefit effects remain outside this example.

Frequently asked questions

Can I enter the loss balance from my assessment unchanged?

Only when it already reflects the current inclusion rate. Older losses may need conversion. Enter eligible post-May-22-1985 losses after that adjustment; special older-loss deductions are outside this model.

Can losses eliminate every tax effect of a gain?

No. Prior-year losses can eliminate its taxable-income addition while the gain still raises net income and reduces a basic personal credit. Other income-tested benefits and recovery taxes can also change, but are excluded here.

Which gains need different treatment?

Principal-residence exemptions, business inventory, superficial losses, listed personal property, depreciable property, reserves, lifetime exemptions, trusts and nonresidents require other rules. Use eligible ordinary gains and losses already determined under CRA rules. AMT and omitted credit phaseouts can make actual incremental tax higher or lower.
