💡 Inclusion Rate: Only 50% of your capital gain is taxable in Canada. The taxable portion is added to your income and taxed at your marginal rate.

How Capital Gains Tax Works in Canada (2026)

In Canada, when you sell an asset for more than you paid, the profit is called a capital gain. Unlike regular income, capital gains receive preferential tax treatment—only a portion of the gain is taxable. This calculator helps you estimate your capital gains tax on stocks, investment properties, businesses, and other assets.

Important 2026 Update: The capital gains inclusion rate remains at 50% for 2026. The proposed increase to 66.67% for gains over $250,000 was cancelled by Prime Minister Mark Carney on March 21, 2025. All capital gains continue to be taxed at the 50% inclusion rate.

Understanding the 50% Inclusion Rate

Canada uses an "inclusion rate" system for capital gains. Currently, only 50% of your capital gain is added to your taxable income. For example:

  • You sell shares for a $100,000 profit (capital gain)
  • Only $50,000 (50%) is added to your taxable income
  • If your marginal tax rate is 40%, you pay $20,000 in tax
  • Your effective tax rate on the gain is only 20% ($20,000 ÷ $100,000)

2026 Capital Gains Tax Rates by Province

Your capital gains tax depends on your province and income level. Here are the top marginal rates on capital gains (after the 50% inclusion):

Province Top Marginal Rate Effective CG Rate Tax on $100K Gain
Alberta 48.00% 24.00% $24,000
British Columbia 53.50% 26.75% $26,750
Manitoba 50.40% 25.20% $25,200
New Brunswick 52.50% 26.25% $26,250
Newfoundland 54.80% 27.40% $27,400
Nova Scotia 54.00% 27.00% $27,000
Ontario 53.53% 26.76% $26,760
Quebec 53.31% 26.65% $26,650
Saskatchewan 47.50% 23.75% $23,750

Principal Residence Exemption

If you sell your principal residence (the home you live in), the entire capital gain is tax-free under the Principal Residence Exemption. This is one of the most valuable tax benefits in Canada:

  • No limit on the exemption amount
  • Must designate the property as your principal residence
  • Only one property per family can be designated per year
  • Important: You must report the sale on Schedule 3, even though no tax is owed

Lifetime Capital Gains Exemption (LCGE)

The LCGE allows tax-free capital gains on certain types of property:

Property Type 2026 LCGE Limit Taxable Above Limit
Qualified Small Business Corporation (QSBC) Shares $1,250,000 50% inclusion
Qualified Farm Property $1,250,000 50% inclusion
Qualified Fishing Property $1,250,000 50% inclusion

The LCGE was increased from approximately $1 million to $1.25 million effective June 25, 2024, and is now indexed to inflation starting in 2026.

Calculating Your Adjusted Cost Base (ACB)

Your ACB is not simply what you paid for an asset. It includes:

  • Original purchase price
  • + Purchase costs: Legal fees, transfer taxes, commissions
  • + Capital improvements: Renovations, additions (not repairs)
  • − Capital returned: Return of capital distributions from funds

Keeping good records of your ACB is essential. For mutual funds and ETFs with reinvested distributions, tracking ACB can be complex—consider using an ACB tracking tool or accountant.

Capital Losses

Capital losses can offset capital gains:

  • Losses first offset gains in the current year
  • Unused losses can be carried back 3 years
  • Unused losses can be carried forward indefinitely
  • Only 50% of the loss is deductible (matching the 50% inclusion rate)
  • Losses cannot offset regular income (except in year of death)

Tax-Loss Harvesting Strategy

Near year-end, consider selling losing investments to realize capital losses that offset gains. Key rules:

  • Avoid the "superficial loss" rule: Don't repurchase the same or identical security within 30 days before or after the sale
  • Consider buying a similar (but not identical) investment if you want to maintain market exposure
  • Both you and "affiliated persons" (spouse, controlled corporations) are subject to the 30-day rule

Frequently Asked Questions

What is the capital gains inclusion rate in 2026?
The capital gains inclusion rate is 50% for 2026. The proposed increase to 66.67% for gains over $250,000 was cancelled by the federal government on March 21, 2025. All capital gains—regardless of amount—are taxed at the 50% inclusion rate.
How do I calculate capital gains on real estate?
Subtract your adjusted cost base (purchase price + buying costs + capital improvements) and selling costs from the sale price. The result is your capital gain. If it's your principal residence, the gain is tax-free. For investment properties, 50% of the gain is added to your income.
Are capital gains taxed in a TFSA or RRSP?
No. Investments in a TFSA grow completely tax-free, including capital gains. In an RRSP, growth is tax-deferred—you pay tax only when you withdraw, but it's taxed as regular income, not capital gains. This is why holding growth investments in a TFSA can be advantageous.
When do I have to pay capital gains tax?
Capital gains tax is due when you file your annual tax return for the year in which you sold the asset. The gain is added to your income for that year. If you expect a large tax bill, you may want to make quarterly installment payments to avoid interest charges.
What qualifies for the Lifetime Capital Gains Exemption?
The LCGE applies to qualified small business corporation (QSBC) shares, qualified farm property, and qualified fishing property. To qualify, QSBC shares must meet specific tests including the 90% asset test and 24-month holding period. Consult a tax professional to ensure your shares qualify.
How do I report capital gains on my tax return?
Report capital gains on Schedule 3 of your T1 tax return. You'll list each disposition (sale), including the proceeds, ACB, and resulting gain or loss. The net taxable capital gain transfers to line 12700 of your return. Keep all supporting documents for at least 6 years.
Can I spread a capital gain over multiple years?
Generally, no—capital gains are taxed in the year of sale. However, you can use a capital gains reserve if you don't receive all proceeds immediately (e.g., vendor take-back mortgage). This allows you to spread the gain over up to 5 years (10 years for family farm/business transfers).
