Capital Gains Tax in Canada 2026: Complete Guide for Investors, Homeowners & Business Owners

Selling an investment, a rental property, a vacation home, or shares in your business? Capital gains tax is one of the most significant — and most misunderstood — taxes Canadians face. Understanding how it works can mean the difference between keeping tens of thousands of dollars or handing it to CRA unnecessarily.

At Booboo Accounting Services, we help investors, landlords, and business owners across Richmond Hill, Markham, Vaughan, and the GTA plan around capital gains strategically. This guide covers everything you need to know for 2026 — including the current inclusion rate, principal residence exemption, lifetime capital gains exemption, and key planning strategies.

💡 Quick Answer: In 2026, individuals include 50% of capital gains up to $250,000 in income, and 2/3 (66.67%) of gains above $250,000. Corporations and trusts include 2/3 of all capital gains. Your principal residence remains fully exempt — but rental properties, cottages, and investments are fully taxable.

🔑 What is a Capital Gain?

A capital gain arises when you sell a capital property for more than its adjusted cost base (ACB) plus selling expenses.

Capital Gain = Proceeds of Disposition – ACB – Selling Costs

Common Capital Properties:

Stocks, ETFs, mutual funds, and cryptocurrency
Rental properties and investment real estate
Vacation homes and cottages
Business assets and goodwill
Shares of private corporations
Land and commercial property

What is Adjusted Cost Base (ACB)?

The ACB is generally what you originally paid for the property, plus any costs to acquire it (commissions, legal fees) and any capital improvements made over time.

ACB Example — Rental Property:

Purchase price: $450,000
Legal fees on purchase: $3,000
New roof added in 2022: $18,000
ACB = $471,000

Sold in 2026 for: $680,000
Real estate commission: $20,400
Capital Gain = $680,000 – $471,000 – $20,400 = $188,600

💰 How Much Tax Will You Actually Pay?

Capital gains are not taxed at a flat rate — the taxable portion (50% or 66.67%) is added to your other income for the year and taxed at your marginal rate.

Example 1: Selling Stocks — Gain of $80,000

Ontario resident, other income $90,000 (marginal rate ~43%)

Gain: $80,000 (under $250K threshold)
Inclusion rate: 50%
Taxable portion added to income: $40,000
Tax on $40,000 at 43%: ~$17,200

Effective tax on $80,000 gain: ~21.5% — not 43%

Example 2: Selling a Cottage — Gain of $400,000

Ontario resident, other income $120,000 (marginal rate ~46%)

First $250,000 of gain:
Inclusion rate: 50% → Taxable: $125,000
Tax at 46%: ~$57,500

Remaining $150,000 of gain:
Inclusion rate: 66.67% → Taxable: $100,000
Tax at 46%: ~$46,000

Total tax: ~$103,500

Effective tax on $400,000 gain: ~25.9%

Strategic planning (timing the sale, spreading across years) could significantly reduce this.

🏠 Principal Residence Exemption (PRE)

Your principal residence is fully exempt from capital gains tax — this is one of the most valuable tax shelters available to Canadians.

Key Rules:

You can only designate one property per family unit per year as your principal residence
The property must be ordinarily inhabited by you, your spouse/common-law partner, or your children
Must be reported on Schedule 3 of your T1 even if fully exempt — CRA requires disclosure
A principal residence can include the land up to ½ hectare (larger lots may have partial exemption)

Partial Exemption — When You Used the Property for Other Purposes:

If you rented out part of your home, ran a business from it, or used it as a rental before moving in, only a portion of the gain may be exempt.

Principal Residence Exemption Formula:

Tax-free portion = Capital Gain × (1 + Years Designated as Principal Residence) ÷ Total Years Owned

Example: Owned for 10 years, designated as principal residence for 8 years.
Tax-free: (1 + 8) ÷ 10 = 90% of the gain is exempt
10% of the gain is taxable.

⚠️ Common Mistake — Failing to Report: Since 2016, you must report the sale of your principal residence on your tax return even if no tax is owing. Failure to report can result in CRA denying the exemption entirely. Our tax preparers ensure proper reporting every time.

🏘️ Capital Gains on Rental Properties

Rental properties do not qualify for the principal residence exemption and are fully subject to capital gains tax. There’s an additional layer: recaptured CCA (depreciation).

Two Taxable Items When You Sell a Rental Property:

Capital Gain — Proceeds minus ACB and selling costs (50%/66.67% inclusion)
Recaptured CCA — Any Capital Cost Allowance (depreciation) you claimed over the years is fully added back to income at 100% — no inclusion rate discount

Rental Property Sale Example

Purchase price (ACB): $400,000
CCA claimed over 12 years: $60,000
Sale price: $700,000
Selling costs: $21,000

Recaptured CCA (100% taxable): $60,000
Capital Gain: $700,000 – $400,000 – $21,000 = $279,000

First $250,000 of gain: 50% included = $125,000
Remaining $29,000: 66.67% included = $19,333
Recapture: $60,000 fully included

Total added to income: $204,333

⚠️ This is why claiming maximum CCA on rental properties isn’t always wise — it creates a tax bill on sale that can surprise landlords.

✅ Planning Tip: If you plan to sell a rental property, talk to us before you list it. Timing the sale across two tax years, managing CCA claims in prior years, and coordinating with other income can meaningfully reduce your bill. Our Richmond Hill tax accountants specialize in rental property tax planning.

📈 Capital Gains on Investments (Stocks, ETFs, Crypto)

Shares and ETFs:

Capital gain or loss is triggered when you sell or dispose of shares — not when they go up in value
ACB must be tracked for each security, including all purchases over time (average cost method for identical properties)
Dividends are taxed differently — not as capital gains
Superficial loss rule: If you sell at a loss and repurchase the same security within 30 days before or after, the loss is denied

Cryptocurrency:

CRA treats crypto as a commodity — every disposition (sale, trade, or use to purchase goods) triggers a capital gain or loss
Must track ACB for every coin purchased across all transactions
Mining income is treated as business income, not capital gains
Staking rewards and DeFi income: CRA’s position continues to evolve — keep detailed records

⚠️ Crypto Warning: CRA has access to transaction data from Canadian exchanges and has been actively auditing crypto investors. “I didn’t think I had to report it” is not a defence. Every trade is a taxable event. If you have multiple years of unreported crypto gains, a voluntary disclosure filed before CRA contacts you can significantly reduce penalties.

💎 Lifetime Capital Gains Exemption (LCGE)

The LCGE allows eligible individuals to shelter up to $1,016,836 (2026) of capital gains from tax when selling shares of a Qualified Small Business Corporation (QSBC) or qualifying farming/fishing property.

QSBC Requirements:

Canadian-controlled private corporation (CCPC)
More than 90% of assets used in active business in Canada at time of sale
More than 50% of assets used in active business throughout the 24 months before sale
Shares held by you or a related person for at least 24 months

LCGE Example: Selling Your Business

Sale price of corporation shares: $1,500,000
Original share cost: $1,000
Capital gain: $1,499,000

Without LCGE (taxable at 50% inclusion):
Taxable income: $749,500
Tax at 46%: ~$344,770

With LCGE applied ($1,016,836 exempt):
Remaining taxable gain: $1,499,000 – $1,016,836 = $482,164
First $250,000 at 50%: $125,000
Remaining $232,164 at 66.67%: $154,782
Total taxable: $279,782
Tax at 46%: ~$128,700

LCGE Tax Savings: ~$216,000!

✅ Start the Clock Early: The 24-month holding requirement means you need to incorporate and structure properly before you’re thinking about selling. If you’re running a successful sole proprietorship, talk to us now about transitioning to a corporation to start LCGE eligibility. Our Richmond Hill accountants help business owners structure for LCGE years in advance.

📉 Capital Losses: Turning Losses Into Tax Savings

A capital loss occurs when you sell a property for less than its ACB. Capital losses can only offset capital gains — they cannot reduce other types of income.

Capital Loss Rules:

Current year: Capital losses first offset capital gains in the same year
Carry back: Net capital losses can be carried back up to 3 years to offset prior capital gains
Carry forward: Unused losses can be carried forward indefinitely
Superficial loss rule: Losses denied if you repurchase the same property within 30 days before or after the sale

Tax Loss Harvesting Example:

You sold a rental property in 2026 and realized a $120,000 capital gain.
You also hold stocks sitting at a $45,000 unrealized loss.

If you sell the losing stocks before December 31, 2026:
Remaining taxable gain: $120,000 – $45,000 = $75,000
Tax saving at 46% marginal rate on $22,500 (50% of $45,000): ~$10,350 saved

Wait until January to repurchase (to avoid superficial loss rule).

🗓️ Key Capital Gains Tax Deadlines

Deadline	What’s Due
April 30, 2027	Personal T1 return reporting 2026 capital gains + tax payment
June 15, 2027	T1 filing deadline if self-employed (but tax owing still due April 30)
December 15, 2026	Last day for tax loss harvesting on publicly traded securities (settlement + 2 days)
December 31, 2026	Last day to trigger a loss on real estate or private shares for 2026

⚠️ Note for Stock Traders: For publicly traded securities, the settlement date determines the tax year — not the trade date. In 2026, Canada moved to T+1 settlement, so a sale on December 30 settles December 31 — still in 2026. A sale on December 31 settles January 2, 2027 and falls into the 2027 tax year. Time your year-end trades carefully.

🚫 Common Capital Gains Mistakes to Avoid

Not tracking ACB accurately — Especially critical for stocks purchased in multiple batches over years; incorrect ACB means overpaying or underpaying tax
Forgetting to report the principal residence exemption — Required since 2016; CRA can deny the exemption if not reported
Ignoring recaptured CCA on rental properties — Surprises sellers who focused only on the capital gain
Triggering superficial losses — Repurchasing within 30 days kills the loss deduction
Not reporting crypto — Every trade, exchange, or purchase is taxable; CRA is actively enforcing this
Missing the $250,000 annual threshold planning opportunity — Spreading large gains across two tax years keeps more gains in the lower 50% inclusion band
Not planning for LCGE — Failing to incorporate early enough to satisfy the 24-month holding requirement
Selling in a high-income year — Adding large gains to an already-high income year pushes them into the top marginal rates

🧠 Capital Gains Planning Strategies

1. Spread Gains Across Two Tax Years

If your gain will exceed $250,000, consider structuring the sale so part of the proceeds fall into the next calendar year — keeping more of the gain under the 50% inclusion rate.

2. Crystallize Gains in Low-Income Years

If you expect lower income in a particular year (retirement, sabbatical, parental leave), that’s often the optimal time to trigger capital gains — the same taxable amount is taxed at a lower marginal rate.

3. Spousal Transfers for Income Splitting

Transferring appreciated assets to a lower-income spouse can shift gains to a lower marginal rate. However, the attribution rules are complex — always get professional advice before doing this.

4. Donate Appreciated Securities Directly

Donating publicly traded securities directly to a registered charity eliminates the capital gain entirely while generating a donation tax credit. This is far more tax-efficient than selling and donating cash.

5. Incorporate and Qualify for LCGE

For business owners, the $1,016,836 LCGE on qualifying small business corporation shares is the single most valuable capital gains shelter available. Planning must begin at least 24 months before any sale.

✅ Key Principle: Capital gains tax planning works best when done years in advance of a disposition. If you’re thinking about selling a property or business, contact our Richmond Hill tax accountants now — not the week before closing.
