If you own a small business in Canada, you have probably been watching the capital gains tax saga unfold over the past two years with a mixture of anxiety and confusion. First the federal government proposed hiking the inclusion rate to two-thirds. Then it was deferred. Then it was cancelled entirely. Through it all, the Lifetime Capital Gains Exemption quietly received its biggest increase in decades — and that change is very much still in effect.

This guide breaks down exactly where things stand with the capital gains tax in Canada for 2026, what the new numbers mean for business owners planning an exit or asset sale, and what strategies you can use right now to keep more of what you have earned. If you are a small business owner in the Greater Toronto Area or anywhere in Canada, this is essential reading before you make your next move.

The Capital Gains Inclusion Rate: 50% Stays Put

What Was Proposed

In the 2024 federal budget, the government proposed increasing the capital gains inclusion rate from one-half (50%) to two-thirds (66.67%). For individuals, the higher rate would have applied to annual capital gains exceeding $250,000. For corporations and most trusts, it would have applied to all capital gains with no threshold.

The business community pushed back hard. The Canadian Federation of Independent Business, industry associations, and tax professionals across the country raised concerns about the impact on business succession, investment, and entrepreneurship.

What Actually Happened

On January 31, 2025, the government deferred the proposed increase to January 1, 2026. Then, on March 21, 2025, the federal government cancelled the proposed inclusion rate increase altogether.

The capital gains inclusion rate in 2026 remains at 50%. This means that when you realize a capital gain — whether from selling shares, investment property, or your business — only half of that gain is added to your taxable income.

For example, if you sell an asset and realize a $500,000 capital gain, $250,000 is included in your income and taxed at your marginal tax rate. The other $250,000 is not taxed at all.

This is welcome news for anyone planning to sell a business, transfer ownership, or dispose of capital property in 2026. The rules you are familiar with remain intact. If you want to understand how these rules interact with your overall tax planning strategy, now is an excellent time to review your position.

The Lifetime Capital Gains Exemption: A Significant Increase

The New LCGE Limit

The biggest positive change for small business owners is the increase to the Lifetime Capital Gains Exemption. Effective June 25, 2024, the LCGE limit jumped from $1,016,836 to $1,250,000 for qualifying dispositions of small business corporation shares and qualified farm or fishing property.

Starting in 2026, the LCGE is indexed to inflation. For the 2026 tax year, the indexed LCGE limit is $1,275,000.

This is a cumulative lifetime exemption. You can claim portions of it across multiple transactions over the course of your life, up to the maximum. Once you have used it all, it is gone.

What This Means in Real Dollars

Let us put this into perspective. If you sell your qualified small business corporation shares and realize a capital gain of $1,275,000 or less in 2026, you could potentially pay zero capital gains tax on that entire amount.

At the 50% inclusion rate and a combined federal-provincial marginal tax rate of roughly 53% (for top earners in Ontario), the LCGE could save you approximately $337,875 in taxes. That is not a rounding error. That is a down payment on your next chapter.

For business owners who have been building equity in their companies for years, this increase provides meaningful breathing room when it comes time to sell. Our small business accounting team works with clients every day to ensure their corporate structures are positioned to take full advantage of the LCGE when the time comes.

Inflation Indexing: Why It Matters

Before the 2024 budget changes, the LCGE was already indexed to inflation, but the jump to $1.25 million represented a significant one-time increase. Now, with inflation indexing resuming in 2026, the exemption will continue to grow each year in line with the Consumer Price Index.

This matters for business owners who are not planning to sell immediately. If your exit is three, five, or ten years away, the LCGE will be higher when you get there. Planning early means you can structure your affairs to maximize the benefit of an exemption that will only grow over time.

Qualified Small Business Corporation Shares: Meeting the Test

The Three Conditions

Not every business sale qualifies for the LCGE. To claim the exemption, the shares you sell must meet the definition of Qualified Small Business Corporation (QSBC) shares. There are three key tests:

1. The ownership test. At the time of sale, the shares must be owned by you (or a related person) and must be shares of a Canadian-Controlled Private Corporation (CCPC).
2. The holding period test. Throughout the 24 months immediately before the sale, the shares must not have been owned by anyone other than you or a person related to you.
3. The asset test. At the time of sale, at least 90% of the fair market value of the corporation’s assets must be used principally in an active business carried on primarily in Canada. For the 24-month period before the sale, at least 50% of the fair market value of the assets must have been used in an active business in Canada.

Common Pitfalls

Many business owners are surprised to learn that passive investments held inside the corporation can disqualify their shares from QSBC status. If your company has accumulated excess cash, marketable securities, or investment real estate, you may fail the 90% active business asset test.

This is one of the most important reasons to work with a qualified accountant well before a planned sale. There are legitimate strategies — such as purifying the corporation by paying dividends, transferring passive assets to a separate holding company, or repaying shareholder loans — that can bring your company back into compliance with the QSBC rules. But these strategies take time to implement properly.

The Canadian Entrepreneurs Incentive: A New Benefit

What Is the CEI?

Introduced in the 2024 federal budget and still moving forward despite the cancellation of the inclusion rate hike, the Canadian Entrepreneurs Incentive (CEI) is a new tax benefit that reduces the capital gains inclusion rate to one-third (33.33%) on a lifetime maximum of eligible capital gains.

The CEI is being phased in starting in the 2025 tax year:

2025: $400,000 lifetime limit
2026: $800,000 lifetime limit
2027: $1,200,000 lifetime limit
2028: $1,600,000 lifetime limit
2029 and beyond: $2,000,000 lifetime limit

How the CEI Works With the LCGE

The CEI applies to capital gains that exceed your LCGE. This means you could potentially shelter up to $1,275,000 in gains through the LCGE in 2026, and then apply the reduced one-third inclusion rate on up to $800,000 of additional gains through the CEI.

On that additional $800,000, you would include only $266,667 (one-third) in your income instead of $400,000 (one-half). At a 53% marginal rate, that is an additional tax saving of roughly $70,667.

Who Qualifies

The CEI has specific eligibility requirements. It applies to qualifying small business shares and farming or fishing property, but certain sectors are excluded. Businesses in restaurants, hotels, arts, entertainment, recreation, finance, insurance, real estate, and professional corporations may not qualify.

Legislation is still being finalized, so the details could shift. This is another area where proactive tax planning pays off — you want to know whether your business qualifies before you finalize a sale.

How Capital Gains Affect Business Sales

Selling Shares vs. Selling Assets

When you sell a business, the transaction is typically structured as either a share sale or an asset sale. The tax implications are dramatically different.

Share sale: You sell your shares in the corporation. The capital gain is the difference between what you receive and your adjusted cost base in the shares. If the shares qualify as QSBC shares, you can claim the LCGE and potentially the CEI.
Asset sale: The corporation sells its assets (equipment, inventory, goodwill, customer lists, real estate). The corporation pays tax on the gains, and then you pay tax again when you extract the after-tax proceeds as dividends. There is no LCGE available on an asset sale because you are not selling shares.

For small business owners, a share sale is almost always more tax-efficient, sometimes dramatically so. However, buyers often prefer asset sales for their own tax reasons (they get to step up the cost base of the assets). This creates a negotiation dynamic that every seller needs to understand.

Having an experienced accounting team in your corner during this process is not optional — it is essential. The difference between a well-structured share sale and a poorly planned asset sale can easily exceed six figures in tax.

The Principal Residence Exemption

While we are talking about capital gains, it is worth mentioning the Principal Residence Exemption (PRE). If you sell a property that has been your principal residence for every year you owned it, the capital gain is generally tax-free.

The PRE remains fully in place for 2026. However, keep a few things in mind:

You must report the sale on your tax return, even if the gain is fully exempt.
Only one property per family unit can be designated as a principal residence for any given year.
If you used part of your home for business or rental purposes, the exemption may be reduced.
The anti-flipping rule (in effect since January 1, 2023) treats gains on properties held less than 12 months as fully taxable business income, not capital gains.

For business owners who also own investment properties or cottages, the interaction between the PRE and capital gains rules requires careful planning. Our personal tax services team can help you navigate this.

Strategies to Minimize Capital Gains Tax in 2026

1. Start QSBC Purification Early

If you are planning to sell your business in the next few years, begin the process of ensuring your corporation meets the QSBC tests now. Remove passive investments, pay down internal loans, and restructure if necessary. The 24-month holding and asset tests mean you cannot fix these issues at the last minute.

2. Use the LCGE and CEI Together

With the LCGE at $1,275,000 and the CEI offering a reduced inclusion rate on up to $800,000 in additional gains for 2026, you could shelter or reduce the tax on up to $2,075,000 in capital gains. If both spouses own shares, these amounts can effectively double.

3. Consider a Family Trust

A properly structured family trust can multiply access to the LCGE by allocating capital gains to multiple beneficiaries, each of whom has their own lifetime exemption. This requires careful planning and must be set up well in advance.

4. Time Your Dispositions

If you have capital losses from other investments, you can use those to offset capital gains in the same year. Capital losses can also be carried back three years or carried forward indefinitely. Timing your asset sales to coincide with available losses can significantly reduce your tax bill.

5. Maximize Your Adjusted Cost Base

Ensure that your adjusted cost base (ACB) in your shares accurately reflects all contributions, reinvested amounts, and other adjustments. An understated ACB means an overstated gain and more tax than necessary. Good bookkeeping throughout the life of your business pays dividends — literally — when it comes time to sell.

6. Plan for the After-Tax Proceeds

Tax planning does not stop at the sale. How you invest the after-tax proceeds, whether you set up an individual pension plan, contribute to RRSPs, or structure your retirement income — all of this matters. The goal is not just to minimize tax on the sale but to optimize your financial position for the years ahead.

Year-End Planning: What to Do Now

Even if selling your business is not imminent, there are steps every small business owner should take in 2026:

Review your corporate structure. Is your corporation still set up to be QSBC-eligible? Have passive investments crept above the threshold? A mid-year review can prevent an unpleasant surprise later.
Update your valuation. Do you know what your business is worth today? A current valuation informs not just exit planning but also insurance, estate planning, and partnership agreements.
Check your LCGE usage. If you have claimed any portion of the LCGE in past years, know your remaining balance. The $1,275,000 limit is cumulative, not annual.
Talk to your accountant. This is not a year to file and forget. The combination of the LCGE increase, the CEI phase-in, and the continued 50% inclusion rate creates a genuinely favourable environment for business owners. But only if you plan for it.

Ready to Plan Your Next Move?

The capital gains tax landscape in Canada for 2026 is more favourable for small business owners than it has been in years. The inclusion rate stays at 50%. The LCGE has increased to $1,275,000 and will continue to grow with inflation. The Canadian Entrepreneurs Incentive is adding another layer of tax savings. But none of these benefits happen automatically — they require proactive planning, proper corporate structure, and professional guidance.

At Insight CPA, we specialize in helping Canadian small business owners navigate exactly these kinds of decisions. Whether you are planning to sell your business this year or a decade from now, the strategies you put in place today will determine how much of the proceeds you actually keep.
