Key takeaways

• Canadian-controlled private corporations (CCPCs) that qualify for the small business deduction pay a combined federal tax rate of 9% on the first $500,000 of active business income, with provincial rates adding between 0% and 4% depending on the province or territory.
• Provincial and territorial small business tax rates vary significantly, and some jurisdictions set their own business limits below or above $500,000, so check the rules where your company is incorporated.
• Passive investment income above $50,000 gradually reduces your access to the small business deduction, and it's fully eliminated once passive income reaches $150,000.
• Choosing the right business structure, whether sole proprietorship, partnership, or corporation, directly affects how your income is taxed and which deductions you can claim.

What qualifies as a small business in Canada?

In Canada, a small business for tax purposes is generally a Canadian-controlled private corporation (CCPC). A CCPC is a corporation that is incorporated in Canada, is not controlled by public corporations or non-residents, and is not listed on a designated stock exchange.

The distinction matters because CCPCs have access to the small business deduction (SBD), which significantly lowers the federal corporate tax rate on qualifying active business income. Not all corporations qualify, though. If your company is classified as a personal services business (PSB), where the incorporated individual would reasonably be considered an employee of the hiring entity, you won't be eligible for the SBD and will face a higher tax rate.

To be treated as a CCPC, your corporation must meet specific ownership and control tests set by the Canada Revenue Agency (CRA). If you're unsure whether your business qualifies, your accountant can help you confirm your status.

Small business deduction (SBD)

The small business deduction is the primary tax benefit available to qualifying CCPCs. It reduces the federal corporate tax rate on the first $500,000 of active business income from 15% down to 9%.

To be eligible for the SBD, your corporation must be a CCPC throughout the tax year. The $500,000 business limit is shared among associated corporations, meaning if you own multiple companies that are associated, the total combined limit is still $500,000.

The SBD applies only to active business income, not to investment income or rental income from associated companies. Your passive investment income can reduce or eliminate the business limit entirely, which is covered in more detail later in this guide.

What are the corporate income tax rates in Canada?

Canada uses a two-tier federal corporate tax system. CCPCs that qualify for the small business deduction pay 9% on active business income up to $500,000. Income above that threshold, or income earned by corporations that don't qualify, is taxed at the general corporate rate of 15%.

Federal corporate tax rates

The general federal corporate tax rate starts at 38%. Two reductions bring it down to the effective rates most businesses actually pay.

• Federal tax abatement. A 10% reduction applies to income earned in a Canadian province or territory, bringing the base rate to 28%.
• General rate reduction. An additional 13% reduction lowers the rate further to 15% for qualifying general business income.
• Small business deduction. For CCPCs with active business income within the $500,000 limit, the rate drops from 28% to 9% (a 19% reduction instead of the 13% general rate reduction).

The result is two effective federal rates: 9% for small business income and 15% for general corporate income. These rates are combined with provincial or territorial taxes to determine your total corporate tax obligation.

Provincial and territorial small business tax rates

How passive investment income affects your tax rate

Passive investment income above $50,000 in a tax year gradually reduces the amount of active business income eligible for the small business deduction. For every $1 of passive income over the $50,000 threshold, the $500,000 business limit is reduced by $5.

This means that once your passive investment income reaches $150,000, the business limit drops to $0, and the SBD is entirely eliminated. At that point, all active business income is taxed at the general federal rate of 15% instead of 9%.

Passive investment income includes earnings such as interest, dividends, rental income, and capital gains. If your corporation holds significant investments, it's worth planning ahead to manage how much passive income flows through the company each year.

Capital gains and investment income tax rates

When your corporation sells an asset for more than its adjusted cost base, the profit is a capital gain. In Canada, 50% of a capital gain is included in taxable income, which is known as the inclusion rate.

For CCPCs earning investment income (including taxable capital gains), the federal tax rate is 38.67%. This higher rate reflects the base 38% rate plus an additional refundable tax of 10.67%, minus the federal tax abatement of 10%. A portion of this tax is refundable when the corporation pays taxable dividends to shareholders.

Understanding how investment income is taxed separately from active business income helps you plan your corporate structure and compensation strategy more effectively.

Non-incorporated vs incorporated business taxation

The way your business income is taxed depends heavily on whether you've incorporated. A sole proprietorship or partnership reports business income directly on the owner's personal T1 tax return. That income is taxed at personal marginal rates, which can reach over 50% in some provinces.

An incorporated business files a separate T2 corporate tax return. Corporate income benefits from the small business deduction and other corporate tax credits that aren't available to unincorporated businesses. However, incorporation also involves additional compliance obligations, including annual corporate filings, maintaining a corporate record, and potentially paying yourself through salary or dividends.

There's no single right answer for every business. The best structure depends on your income level, growth plans, and how you intend to draw money from the business. Consulting with an accountant who understands your situation is the most reliable way to determine whether incorporating makes sense.

How to calculate your small business tax rate

Calculating your combined small business tax rate is straightforward once you know your province and your qualifying income. Here's how to work through it step by step.

1. Confirm your corporation qualifies as a CCPC. Your business must be a Canadian-controlled private corporation to access the small business deduction.
2. Determine your active business income. Only active business income up to the business limit (typically $500,000) qualifies for the lower rate. Investment and rental income are taxed differently.
3. Apply the federal small business rate. The federal rate for qualifying income is 9%.
4. Add your provincial or territorial small business rate. Check the rates for your jurisdiction in the section above.
5. Calculate the total. Add the federal and provincial rates together to get your combined small business tax rate.

For example, if your CCPC earns $100,000 in active business income in British Columbia, you'd pay 9% federal plus 2% provincial, for a combined rate of 11%. That works out to $11,000 in total corporate income tax on that income.

GST/HST requirements for small businesses

If your business earns more than $30,000 in revenue over four consecutive calendar quarters, you're required to register for and charge GST/HST. Below that threshold, registration is optional, but there are reasons you might want to register voluntarily.

When you're registered, you collect GST/HST on your taxable sales and remit it to the CRA. You can also claim Input Tax Credits (ITCs) to recover the GST/HST you've paid on business expenses. For many small businesses, ITCs can offset a meaningful portion of the tax collected, reducing the net amount you owe.

The CRA's GST/HST registration page outlines the full requirements and steps for registration. For a deeper look at how GST, HST, and PST work across provinces, see Xero's guide to GST/HST and PST returns.

Tax due dates

Corporate tax filing and payment deadlines in Canada depend on your fiscal year-end and the size of your business. Missing these dates can result in penalties and interest charges.

• Filing deadline. Your T2 corporate tax return is due six months after your fiscal year-end. If your year-end is 31 December, the filing deadline is 30 June.
• Payment deadline (general). Corporate income tax is due two months after your fiscal year-end. For a 31 December year-end, that means 28 February.
• Payment deadline (qualifying small businesses). CCPCs that meet certain conditions, including claiming the small business deduction and having taxable income under $500,000 in the prior year, get an extra month. Their payment deadline is three months after the fiscal year-end, or 31 March for a 31 December year-end.

The filing and payment deadlines are separate. Even if you have three months to pay, you still need to file within six months. The CRA's page on when to file your corporation income tax return provides full details and exceptions.

How to reduce your tax burden

There are several legitimate strategies you can use to lower the amount of corporate tax your small business pays. Planning ahead and keeping clean records makes it easier to take full advantage of available tax deductions.

• Capital cost allowance (CCA).CCA lets you deduct the cost of depreciable assets, such as equipment, vehicles, and technology, over time rather than all at once. Each asset class has its own depreciation rate set by the CRA.
• Input Tax Credits (ITCs). If you're registered for GST/HST, you can claim ITCs to recover the tax paid on eligible business purchases. This directly reduces your net GST/HST remittance.
• Investment Tax Credits. Certain expenditures, such as scientific research and experimental development (SR&ED), qualify for investment tax credits that reduce your federal tax payable.
• Environmental credits. Clean technology and carbon capture investments may qualify for federal investment tax credits, which can further lower your tax bill.
• Income splitting through salary and dividends. Paying yourself a mix of salary and dividends from your corporation can help manage your overall tax burden across personal and corporate returns, though the Tax on Split Income (TOSI) rules limit some strategies.

Working with an accountant to identify which deductions and credits apply to your specific situation is one of the most effective ways to keep your tax bill as low as possible.

FAQs on small business tax rates in Canada

Here are answers to some common questions about small business taxes in Canada that aren't covered in the sections above.

Can associated corporations share the $500,000 business limit?

Yes, but the $500,000 federal business limit must be divided among all associated corporations using a joint election filed with the CRA on Schedule 23. The total across all associated corporations cannot exceed $500,000.

What happens if I miss the corporate tax payment deadline?

The CRA charges compound daily interest on any unpaid balance starting the day after the payment deadline. A late-filing penalty of 5% of the unpaid tax, plus 1% for each full month the return is late (up to 12 months), also applies.

Do I need to charge GST/HST on all my sales?

Not necessarily. Some goods and services are exempt (such as most health services) or zero-rated (such as basic groceries), meaning GST/HST either doesn't apply or is charged at 0%.

What records should I keep for the CRA?

You're required to keep all business records, including receipts, invoices, bank statements, and contracts, for at least six years from the end of the tax year they relate to. Digital records are acceptable as long as they're legible, organized, and available for CRA review.

Can I change my corporation's fiscal year-end?

Yes, but you need CRA approval and must file a short tax year return for the transition period. The new fiscal year-end must be within 53 weeks of the previous one.
