Selling a business or real estate can be a significant financial milestone, but it also comes with tax implications — particularly capital gains tax. If you’re selling a business, investment property, or shares, careful tax planning can help minimize your tax liability and maximize your profits.
Here’s a guide to walk you through capital gains tax planning, including exemptions, deferrals, and installment sales, to help you make informed financial decisions and reduce tax burdens when selling high-value assets.
What Is Capital Gains Tax?
Capital gains tax is the tax imposed on the profit from selling a capital asset, such as a business, real estate, or investments. The gain is calculated as the difference between the selling price and the adjusted cost base (ACB), which includes the original purchase price and related acquisition costs.
In Canada, 50% of the capital gain is taxable, meaning that only half of your profit is added to your taxable income for the year. However, various strategies can help reduce or defer this tax liability.
Short-Term vs. Long-Term Planning
- Short-term:Minimizing tax liability within the current tax year.
- Long-term:Structuring the sale over multiple years to spread out the taxable gains and potentially stay in a lower tax bracket.
Key Strategies to Minimize Capital Gains Tax

Use deferrals and installment sales to spread tax payments over time.
1. Utilize the Lifetime Capital Gains Exemption (LCGE)
The Lifetime Capital Gains Exemption (LCGE) is a major tax-saving tool for Canadian business owners selling shares of a Qualified Small Business Corporation (QSBC) or eligible farming/fishing properties.
How It Works:
- As of 2024, the LCGE allows individuals to shelter up to $1,016,836of capital gains from tax when selling QSBC shares.
- Only 50% of capital gains are taxable, meaning up to $508,418 of taxable income can be exempted.
- To qualify, the business must be a Canadian-controlled private corporation(CCPC)
Planning Tip:
- Restructure your business before selling to meet QSBC eligibility requirements.
- Hold shares for at least 24 months before selling to maximize LCGE benefits.
2. Capital Gains Deferral Through a Section 85 Rollover
A Section 85 Rollover allows business owners to transfer assets (such as shares or real estate) to a corporation in exchange for shares, deferring capital gains tax until a later sale.
Benefits:
- Allows for tax-efficient business succession planning.
- Defers tax liability to when the shares are eventually sold.
- Useful for transferring businesses within families or corporate reorganizations.
Planning Tip:
- Work with an accounting expert in Ontarioto structure the transaction properly and avoid unnecessary tax liabilities.
3. Use an Installment Sale to Spread Out Taxable Gains
If you sell a business or real estate for a large profit, you can structure the sale as an installment sale, spreading payments over multiple years.
How It Works:
- Instead of receiving a lump sum, the buyer makes installment payments over time.
- You only report the portion of capital gains received each year, reducing overall tax liability.
Example:
- If you sell a business for $1,000,000 and receive payments over 5 years, you can spread out the tax burden instead of paying it all at once.
4. Tax Deferral with Capital Gains Reserve

Plan ahead to minimize tax burdens when selling business assets.
The Capital Gains Reserve allows sellers to defer recognizing capital gains if full payment isn’t received upfront.
Key Rules:
- You must receive at least 10% of the sale price each year.
- The maximum deferral period is 5 years.
- Each year, a portion of the gain is included in income based on the payments received.
Planning Tip:
- Combine this with an installment sale to manage cash flow and taxation effectively.
5. Capital Gains Exemption for Principal Residences
If you’re selling your primary residence, you may qualify for the Principal Residence Exemption (PRE), which allows you to avoid capital gains tax entirely.
Qualifications:
- The property must be your primary residence for every year you owned it.
- If you rented it out, the exemption might be limited.
- One property per family unit can be designated as a principal residence per tax year.
6. Offset Gains with Capital Losses
If you have investments that have decreased in value, you can use capital losses to offset capital gains.
How It Works:
- Current year losses offset current year gains.
- Unused losses can be carried back 3 years or forward indefinitely.
- Reduces taxable income and lowers overall tax liability.
Planning Tip:
- If you anticipate significant gains, consider selling underperforming investments in the same year to offset gains.
Example Scenarios
Example 1: Selling a Small Business
- Sarah owns a Canadian-controlled private corporation (CCPC).
- She sells her shares for $900,000 and claims the Lifetime Capital Gains Exemption (LCGE).
- Because her gain is under the $1,016,836 LCGE limit, she pays zero tax on the sale.
Example 2: Selling Investment Property
- John sells a rental property for $800,000, with an original purchase price of $500,000.
- His capital gain is $300,000, with $150,000 being taxable.
- He spreads payments over 5 years, reducing his annual taxable income.
Example 3: Offsetting Gains with Losses
- Emily sells an investment for a $50,000 capital gain.
- She also sells a poor-performing stock at a $20,000 capital loss.
- Her net taxable gain is reduced to $30,000, lowering her tax bill.
Common Mistakes to Avoid
Here are some common mistakes that you should avoid:
- Not Planning Ahead– Selling without considering tax strategies can lead to unnecessary tax burdens.
- Missing Out on Exemptions– Many business owners fail to qualify for the LCGE due to improper structuring.
- Not Keeping Records– Lack of documentation can lead to incorrect tax filings.
- Ignoring Installment Sale Options– Paying all taxes upfront instead of spreading liability over time.
- Failing to Offset Gains with Losses– Not using capital losses to reduce overall taxable income.
