Make smarter tax decisions with the right capital gains knowledge
When you sell investments, real estate, or business assets for a profit in Canada, you face capital gains tax. The financial products you use and the accounts you hold affect how much tax you ultimately pay.
This guide explains how capital gains tax works, what’s taxable, what’s exempt, and how to calculate what you owe. Whether you’re selling stocks, a cottage, or a small business, you’ll understand your tax obligations.
What is capital gains tax
Capital gains tax applies to the profit you make when selling certain assets. A capital gain is the difference between what you paid for an asset and what you sold it for.
Canada doesn’t tax the full profit. Instead, a portion called the inclusion rate determines how much gets added to your taxable income. That included amount is then taxed at your marginal tax rate.
Assets that trigger capital gains include stocks, bonds, mutual funds, ETFs, real estate beyond your primary home, cryptocurrency, business shares, and valuable collectibles.
How the inclusion rate works
The inclusion rate is the percentage of your capital gain that becomes taxable. For decades, Canada has used a 50% inclusion rate. This means half your gain is tax-free, and half gets added to your income.
If you sell stock for a $10,000 gain, only $5,000 is taxable. If you’re in a 40% marginal tax bracket, you pay $2,000 in tax. That’s an effective rate of 20% on the original $10,000 gain.
A proposed increase to a 66.67% inclusion rate for gains above $250,000 was introduced in 2024 but cancelled in early 2025. The 50% rate remains in effect for all taxpayers as of 2026.
Current rates for 2026
| Taxpayer Type | Inclusion Rate | Threshold |
|---|---|---|
| Individuals | 50% | All gains |
| Corporations | 50% | All gains |
| Trusts | 50% | All gains |
Calculate your capital gains
Calculating capital gains involves three steps: determine your adjusted cost base, calculate proceeds of disposition, then apply the inclusion rate.
Step one: Adjusted cost base
Your adjusted cost base (ACB) is what you paid for the asset, including purchase costs like commissions and legal fees. For investments bought multiple times, you must average all purchases.
Reinvested distributions increase your ACB. When an ETF pays a distribution that automatically reinvests, that amount adds to your cost base. Failing to track this means overpaying tax.
Step two: Proceeds calculation
Proceeds of disposition equal your sale price minus selling costs. These costs include brokerage commissions, legal fees, and in some cases transfer taxes.
Subtract your ACB and selling costs from your proceeds. If the result is positive, you have a capital gain. If negative, you have a capital loss.
Step three: Apply inclusion rate
Multiply your capital gain by 50% to get your taxable capital gain. This amount flows to line 12700 of your T1 return and adds to your total income.
| Step | Example Amount | Calculation |
|---|---|---|
| Sale price | $50,000 | Total proceeds |
| Selling costs | $500 | Commissions, fees |
| Adjusted cost base | $30,000 | Original cost + purchases |
| Capital gain | $19,500 | $50,000 – $500 – $30,000 |
| Taxable gain (50%) | $9,750 | Added to income |
Principal residence exemption
Your primary home is typically exempt from capital gains tax under the principal residence exemption. This is one of Canada’s most valuable tax benefits for homeowners.
To qualify, the property must be ordinarily inhabited by you or a family member during the years you owned it. You can only designate one property as your principal residence for any given year.
- Full exemption: If the home was your principal residence for every year of ownership, the entire gain is tax-free
- Designation required: You must file form T2091 with your tax return to claim the exemption, even when no tax is owing
- One per family: Only one property per family unit can be designated as a principal residence for each year
If you owned the home for some years as a principal residence and others as a rental, you can claim a partial exemption for the years it was your primary home.
Other capital gains exemptions
Beyond the principal residence exemption, Canada offers other ways to shelter capital gains from tax.
Lifetime capital gains exemption
The lifetime capital gains exemption (LCGE) shelters gains from selling qualified small business corporation shares or qualified farm and fishing property. As of 2024, the exemption increased to $1.25 million.
To qualify for small business shares, the corporation must be a Canadian-controlled private corporation. At least 90% of its assets must be used in an active business carried on primarily in Canada.
You must have held the shares for at least 24 months. During that period, more than 50% of the corporation’s assets must have been used in an active Canadian business.
Registered account exemptions
TFSAs, RRSPs, FHSAs, and RESPs shelter all investment growth from tax. When you sell investments inside these accounts, no capital gains tax applies regardless of profit size.
Maximizing contributions to these registered accounts is one of the most effective strategies to avoid capital gains tax entirely. Consider using high-interest savings accounts within your TFSA for tax-free growth.
How capital losses work
When you sell an asset for less than you paid, you have a capital loss. These losses offset capital gains in the same year.
If your losses exceed your gains, you have a net capital loss. You can carry this loss back three years or forward indefinitely to offset future gains.
- Current year offset: Capital losses first reduce capital gains in the same tax year
- Carry back: Net capital losses can be applied to the previous three years to recover taxes already paid
- Carry forward: Unused losses carry forward indefinitely to offset future capital gains
- Same inclusion rate: Losses use the same 50% inclusion rate as gains when calculating the deductible amount
Strategic loss harvesting involves selling losing investments before year-end to offset gains realized earlier in the year. This reduces your current tax bill.
Report capital gains on your return
Capital gains are reported on Schedule 3 of your T1 personal tax return. The net taxable capital gain flows to line 12700 of your main T1 form.
You must report all capital gains and losses, even if you didn’t receive a tax slip. The T5008 slip reports proceeds only, not your gain or loss.
Required documentation
- Purchase records: Keep receipts, confirmations, and statements showing your original cost
- Sale confirmations: Brokerage statements and legal documents proving proceeds and selling costs
- Reinvestment tracking: Records of all distributions reinvested to calculate accurate ACB
- Principal residence forms: Form T2091 must be filed when claiming the principal residence exemption
Common reporting scenarios
Mutual fund distributions appear on your T3 slip as capital gains. These represent your share of the fund’s gains and are already calculated at the fund level.
When you sell the fund units themselves, you calculate a separate gain based on your ACB for those units. Both amounts can apply in the same year.
Cryptocurrency sales must be reported as capital gains. The Canada Revenue Agency treats cryptocurrency as a commodity, not currency, making it subject to capital gains rules.
Special situations and strategies
Inherited property
When someone dies, their estate pays capital gains tax through deemed disposition rules. The deceased is treated as having sold all capital property at fair market value immediately before death.
When you inherit property, your ACB becomes the fair market value at the date of death. You only pay capital gains on appreciation that occurs after you inherit.
Reserves for installment sales
If you receive payment over several years when selling property, you can claim a reserve to defer a portion of the gain. This spreads the tax over multiple years.
The reserve can’t be claimed if you weren’t a Canadian resident at year-end, were tax-exempt, or sold to a corporation you control.
Small business deferral
You can defer capital gains on eligible small business corporation shares if you reinvest the proceeds into another eligible small business within 120 days after year-end.
The shares must have been held for more than 185 days. The ACB of your new investment is reduced by the deferred gain.
Bottom Line
Capital gains tax in Canada uses a 50% inclusion rate, meaning half your profit is tax-free and half is added to your income. Your primary residence escapes this tax entirely through the principal residence exemption, but investment properties, stocks outside registered accounts, and business sales all trigger capital gains.
The most effective strategy is maximizing registered accounts like TFSAs and RRSPs where gains are completely tax-sheltered. For non-registered investments, track your adjusted cost base carefully, harvest losses strategically, and consider the timing of large sales.
If you’re selling a business or qualified farm property, the lifetime capital gains exemption can shelter up to $1.25 million in gains. Proper planning before the sale ensures you meet all qualifying conditions.

How do I calculate my adjusted cost base for stocks?
Your adjusted cost base (ACB) for stocks includes your original purchase price plus commissions and fees. If you bought the same stock multiple times, you must average all purchases. Reinvested distributions increase your ACB, while return of capital distributions reduce it. Accurate ACB tracking is essential to avoid overpaying tax.
Can I use capital losses to reduce my taxes?
Yes, capital losses offset capital gains in the same year. If your losses exceed your gains, you create a net capital loss that can be carried back three years or forward indefinitely. This allows you to recover taxes paid on previous gains or reduce future tax bills when you realize gains.
What is the lifetime capital gains exemption amount?
The lifetime capital gains exemption (LCGE) is $1.25 million as of 2024 and is indexed to inflation from 2026 onwards.

Do I pay capital gains tax on investments in my TFSA or RRSP?
No, investments held in TFSAs, RRSPs, FHSAs, and RRIFs grow completely tax-free. Capital gains inside these registered accounts are invisible to the Canada Revenue Agency. Only gains on investments held in non-registered (taxable) accounts are subject to capital gains tax.
When do I need to report capital gains to the CRA?
You must report capital gains on Schedule 3 of your T1 return for the year you sold the asset. This applies even if you didn’t receive a T5008 slip. If you sold your principal residence, you must file form T2091 to claim the exemption, even when no tax is owing.
Are capital gains on cryptocurrency taxable in Canada?
