Small Business Tax Rate in Canada: 2026 Rates Explained

The "small business tax rate" in Canada is 9% federal, plus a provincial rate between 0% and 3.2%, for a combined rate of roughly 9% to 12% in 2026. The catch that trips up most searchers: this is a corporate rate. Only a Canadian-controlled private corporation gets it, and only on its active business income up to $500,000 a year. If you run an unincorporated business as a sole proprietor, you never pay this rate at all. Your profit is taxed at your personal marginal rate on your T1 return. This guide explains the rate, who qualifies, the 2026 numbers province by province, and what quietly shrinks that $500,000 limit.

The short answer

The small business tax rate is the reduced corporate income tax rate a Canadian-controlled private corporation (a CCPC) pays on its active business income, thanks to the federal small business deduction. Federally, it cuts the corporate rate on the first $500,000 of active income from the 15% general rate down to 9%. Each province and territory adds its own small business rate on top, so the combined rate for 2026 lands between 9% (Manitoba and Yukon) and 12% (Nunavut).

A sole proprietorship or a partnership is not a corporation, so none of this applies. An unincorporated owner pays personal income tax rates on business profit, which for 2026 run from 14% federally up to 33%, plus provincial rates, plus both halves of the Canada Pension Plan. The low corporate rate is a reason some owners incorporate, not something every small business receives.

How the small business tax rate is built

Start with how corporate tax is built. A corporation's basic federal rate is 38% of taxable income. The federal abatement drops that by 10 percentage points to 28% on income earned in a province. The general rate reduction takes off another 13 points, leaving a net general federal rate of 15%.

The small business deduction is a further cut on top of that, but only for a CCPC and only on qualifying income. It lowers the federal rate on the first $500,000 of active business income to 9%. That $500,000 ceiling is called the business limit.

So a CCPC pays two federal rates in the same year: 9% on active income inside the business limit, and 15% on active income above it (or on income that doesn't qualify). Provinces mirror this with their own two-rate system, a lower rate for small business income and a higher general rate.

Who qualifies, and who doesn't

Three conditions all have to be true before a dollar of profit gets the 9% federal rate:

1. You're incorporated. The rate is a corporate rate. Sole proprietors and partnerships file on the personal T1 and are taxed at personal marginal rates, full stop.
2. The corporation is a CCPC. It must be private (not publicly traded) and Canadian-controlled (not controlled, directly or indirectly, by non-residents or public corporations). A corporation controlled by a foreign parent does not qualify.
3. The income is active business income. The deduction applies to income from actively carrying on a business, not to passive investment income like interest, rent, royalties, or portfolio dividends.

One trap sits inside condition 3. An incorporated contractor who would be an employee of the client if not for the corporation can be treated as a personal services business. A personal services business is barred from the small business deduction and the general rate reduction, so it pays the full federal rate (plus provincial), and it can deduct almost no expenses. Incorporating does not, on its own, turn employment income into small business income.

Small business tax rates by province for 2026

The combined rate is the federal 9% plus your province's or territory's own small business rate. The table below shows the 2026 provincial rates and business limits. Alberta and Quebec collect their own corporate tax outside the CRA system; the rest are administered by the CRA.

Three provinces changed their rate in 2026, so watch the effective dates:

• Ontario cuts its small business rate from 3.2% to 2.2% on July 1, 2026. A corporation with a December year-end pays a blended provincial rate for the 2026 tax year, part at 3.2% and part at 2.2%.
• Quebec raised its small business deduction so the effective small business rate falls from 3.2% to 2.2% for tax years beginning after April 29, 2026. Quebec also has its own eligibility test based on paid hours or sector, so not every CCPC gets Quebec's lowest rate.
• Newfoundland and Labrador cut its rate to 2% for 2026 (from 2.5%), on a path to 1.5% in 2027 and 1% in 2028.

Notice that Nova Scotia, Prince Edward Island, and Saskatchewan set their business limit above $500,000. When a province's limit is higher than the federal $500,000, income between the two ceilings still gets the provincial small business rate but the federal general rate, because Ottawa's business limit stays at $500,000.

What shrinks the $500,000 business limit

The $500,000 limit is not guaranteed. Three things reduce it.

Associated corporations share one limit. If you control more than one corporation, or your corporations are associated under the rules, they don't each get $500,000. They split a single $500,000 limit between them and file an agreement allocating it. Setting up a second company does not double your access to the low rate.

Passive investment income grinds it down. When a CCPC and its associated corporations earn more than $50,000 of adjusted aggregate investment income (roughly, passive income from investments) in a year, the business limit falls by $5 for every $1 of that income above $50,000. It reaches zero at $150,000 of passive income. Say a CCPC earns $80,000 of adjusted aggregate investment income: that's $30,000 over the threshold, so the business limit drops by 5 × $30,000 = $150,000, leaving $350,000 of active income still eligible for the 9% rate.

Large corporations lose it too. The business limit also phases out as taxable capital employed in Canada rises from $10 million to $50 million (this range was widened from $15 million by the 2022 federal budget). Where both the passive income and taxable capital reductions apply, the CRA uses whichever cut is larger. Most owner-operated businesses never come near $10 million of taxable capital, so the passive income grind is the one that bites first.

What this means if you're not incorporated

If you run a sole proprietorship, the small business tax rate is not yours to claim. You report business income on Form T2125, it's added to your other income, and it's taxed at your personal marginal rate, whether you spend the profit or leave it in the business account. The low corporate rate only exists for a separate legal taxpayer, the corporation, on the profit it keeps inside.

That's exactly why the incorporate-or-not decision turns on whether you retain earnings. A business that pays out everything it makes usually lands in a similar place either way, because money drawn from a corporation is taxed again in your hands. A business that banks a large share of its profit to reinvest can defer personal tax by leaving it in the company at 9% to 12%.

Whichever structure you're in, the rate applies to profit, and profit is income minus deductible expenses. Every receipt you can support lowers the income the rate is charged on, and the CRA can ask to see the record behind each claim for six years. SparkReceipt captures each receipt, reads the GST/HST off it, sorts your expenses into CRA-ready categories, and keeps the image on file. It also scans receipts in seconds and publishes clean, categorized data straight to QuickBooks Online or Xero, so the income figure the rate lands on is one you can stand behind. Before you claim vehicle or capital cost allowance or the other deductions a business can take, the records have to be there.

Frequently asked questions

Do sole proprietors pay the small business tax rate? No. The small business tax rate is a corporate rate for a Canadian-controlled private corporation. A sole proprietor pays personal income tax rates on business profit, reported on Form T2125 with the T1 return.

What is the federal small business tax rate for 2026? 9% on the first $500,000 of a CCPC's active business income. Active income above that, or income that doesn't qualify, is taxed at the 15% general federal rate. Provinces add their own rate on top of both.

Why is my combined rate higher than 9%? Because 9% is only the federal share. Your province or territory adds its small business rate, from 0% in Manitoba and Yukon up to 3.2% in Ontario before its July 2026 cut, giving a combined rate of roughly 9% to 12%.

Can I set up two corporations to get two $500,000 limits? No. Associated corporations share a single $500,000 business limit and file an agreement allocating it between them. Passive investment income and large taxable capital can shrink that shared limit further.

Does investment income get the small business rate? No. The deduction applies only to active business income. Passive investment income is taxed at high corporate rates, and once it tops $50,000 a year it also starts eroding the $500,000 business limit on your active income.

Key takeaways

• The small business tax rate is a CCPC rate: 9% federal plus a 0% to 3.2% provincial rate, for a 2026 combined rate of about 9% to 12%.
• It applies only to a Canadian-controlled private corporation's active business income up to a $500,000 business limit, not to every small business.
• Sole proprietors and partnerships never see this rate; their profit is taxed at personal marginal rates on the T1 through Form T2125.
• Ontario, Quebec, and Newfoundland and Labrador all cut their small business rate in 2026, so confirm the effective date for your year-end.
• The $500,000 limit is shared among associated corporations and shrinks once passive investment income tops $50,000 or taxable capital tops $10 million.
• The rate is charged on profit, so clean, complete expense records are what keep the income figure, and the tax on it, defensible.
