Canadian corporations must account for federal income tax and, in most cases, provincial or territorial income tax. The amount they pay depends on taxable income, the corporation’s status, the type of income it earns and the province where it operates. A company that qualifies for the small business deduction may pay a much lower rate on eligible income than a corporation that pays the general rate.
Finsoul Network Canada helps businesses understand their financial obligations and plan for tax payments. This guide explains corporate tax rates in Canada 2026, compares federal and provincial rates, covers small business eligibility, and shows how corporations can calculate their tax obligations.
Federal Corporate Tax Rate Canada 2026
The federal government applies different corporate income tax rates depending on the type of corporation and its eligibility for tax deductions. The two main rates for ordinary active business income are 9% and 15%.
The 9% Federal Small Business Tax Rate
Canadian-controlled private corporations (CCPCs) can pay a 9% federal tax rate on qualifying active business income when they claim the small business deduction (SBD). The federal business limit generally stands at $500,000 per year.
A qualifying corporation may use this lower rate on income from eligible business activities, subject to the applicable rules. The limit does not automatically apply separately to every corporation within the same associated group. Associated corporations generally share the available business limit.
The small business tax rate Canada 2026 can help eligible companies retain more earnings for equipment purchases, hiring, debt repayment and other business needs.
The 15% Federal General Corporate Tax Rate
Corporations generally pay a 15% federal net tax rate on active business income that does not qualify for the small business deduction. The general corporate tax rate Canada applies when a company exceeds its available business limit or fails to meet the eligibility requirements.
The federal rate also varies for certain income categories. For example, qualifying manufacturers of zero-emission technology may receive a reduced federal rate, while personal services businesses and corporations that earn investment income face separate rules.
Provincial Corporate Tax Rates Canada 2026
Each province and territory sets its own corporate income tax rates. Most jurisdictions apply a lower rate to eligible small business income and a higher rate to other taxable income.
The following table compares the main provincial and territorial rates for 2026. The combined figures add the applicable federal rate to the provincial or territorial rate for ordinary active business income.
| Province or territory | Small business rate | General rate | Combined small business rate | Combined general rate |
| Alberta | 2% | 8% | 11% | 23% |
| British Columbia | 2% | 12% | 11% | 27% |
| Manitoba | 0% | 12% | 9% | 27% |
| Ontario | 2.2% from July 1 | 11.5% | 11.2% from July 1 | 26.5% |
| Quebec | 3.2% or 2.2%* | 11.5% | 12.2% or 11.2%* | 26.5% |
| Saskatchewan | 1% | 12% | 10% | 27% |
| Nova Scotia | 1.5% | 14% | 10.5% | 29% |
Quebec’s 2.2% rate applies to eligible taxation years beginning after April 29, 2026. Ontario’s reduced rate took effect on July 1, 2026. Rates and eligibility rules should be verified before filing.
Which Provinces Have the Lowest Corporate Tax Rates?
The lowest rate depends on the type of income a corporation earns. Manitoba and Yukon have a 0% provincial small business tax rate, giving eligible corporations a combined federal and provincial rate of 9%. Saskatchewan and Prince Edward Island have a 1% provincial small business rate, resulting in a combined rate of 10%. Alberta has the lowest general provincial corporate tax rate at 8%, which brings its combined general rate to 23%.
Businesses should also consider operating expenses, employee costs, customer locations and provincial filing requirements before choosing where to operate.
How Federal and Provincial Corporate Tax Rates Work Together
The combined federal and provincial corporate tax rate represents the total nominal income tax rate that applies to a particular category of corporate income.
For a corporation with eligible small business income, the calculation generally starts with the 9% federal rate and adds the provincial small business rate. A corporation subject to the general rate typically combines the 15% federal rate with the provincial general rate.
The total rate provides a useful starting point for budgeting, but it does not represent every tax obligation a company may face. Tax deductions, credits, special taxes and income allocation can change the final amount payable.
Who Qualifies for the Small Business Corporate Tax Rate?
Not every incorporated business qualifies for the small business deduction. The Canada corporate tax rates 2026 depend partly on the corporation’s ownership, income and available business limit.
Canadian-Controlled Private Corporation Requirements
A CCPC generally must meet Canadian ownership and control requirements under federal tax law. A corporation controlled by non-residents or public corporations may not qualify.
The corporation must also earn income that meets the active business income rules. Incorporation alone does not grant access to the reduced rate.
How the $500,000 Small Business Limit Works
The federal small business limit generally applies to the first $500,000 of eligible active business income. Associated corporations must share the federal limit, and some provinces set different limits.
For example, Nova Scotia has a $700,000 provincial business limit, while Saskatchewan and Prince Edward Island have $600,000 limits. A corporation must check the federal and provincial rules separately before calculating its tax.
How Passive Income and Taxable Capital Affect Eligibility
A CCPC’s access to the small business deduction can decrease when its associated group earns significant passive investment income or holds substantial taxable capital.
The federal rules generally reduce the business limit when adjusted aggregate investment income falls between $50,000 and $150,000. A separate taxable capital phase-out applies when the relevant amount falls between $10 million and $50 million.
These restrictions can reduce or eliminate the amount of income that qualifies for the lower rate.
How Investment Income and Special Business Income Are Taxed
The standard rates do not cover every type of corporate income. A corporation must identify its income category before applying the correct rules.
Passive Investment Income
Interest, portfolio income and certain rental income may fall under passive investment rules rather than the standard active business rates. A CCPC may face a higher initial tax rate on investment income, with refundable tax mechanisms that can return some tax when the corporation pays taxable dividends.
The treatment depends on the income type, the corporation’s status and the applicable provincial rules.
Personal Services Business Income
A corporation may qualify as a personal services business (PSB) when an incorporated worker provides services in circumstances that resemble an employment relationship with a client.
PSBs face a special federal tax rate and restrictions on deductible expenses. A contractor should review the working relationship and relevant tax rules before assuming the corporation qualifies for the standard small business rate.
Certain financial institutions and qualifying manufacturers of zero-emission technology also face special tax rules.
What Happens When a Corporation Operates in Multiple Provinces?
A corporation that earns income in more than one province may need to allocate its taxable income among the relevant jurisdictions. Its head office address does not automatically determine where it pays all provincial corporate income tax.
The allocation generally depends on the corporation’s permanent establishments and the applicable income allocation rules. Factors such as employee salaries and gross revenue can affect the calculation.
Corporations that operate across provincial borders should:
- Identify each province or territory where they maintain a permanent establishment.
- Calculate the taxable income allocated to each jurisdiction.
- Complete Schedule 5 of the T2 Corporation Income Tax Return when required.
- Review separate provincial filing and payment requirements.
Alberta and Quebec administer their own provincial corporate income tax systems rather than collecting provincial corporate tax through the CRA’s collection agreements. Corporations with a permanent establishment in either province must follow that province’s filing and payment procedures.
What Changed in Corporate Tax Rates in Canada 2026?
Businesses should pay attention to effective dates because some rate changes took effect during the calendar year.
Ontario’s Small Business Rate Reduction
Ontario reduced its small business corporate income tax rate from 3.2% to 2.2%, effective July 1, 2026. Eligible corporations with tax years that include this date must apply the appropriate rate calculation for their tax period.
Newfoundland and Labrador’s Rate Reduction
Newfoundland and Labrador reduced its provincial small business rate from 2.5% to 2% effective January 1, 2026. The province has also announced further reductions for later years, subject to the relevant rules.
Quebec’s Small Business Rate Reduction
Quebec announced a reduction in the minimum small business tax rate from 3.2% to 2.2% for eligible taxation years beginning after April 29, 2026. The deduction has additional requirements, including rules related to paid employee hours and qualifying business activities.
These changes affect the provincial portion of the tax calculation. The federal general rate remains 15%, while the federal small business rate remains 9% for eligible income.
What Should You Check Before Filing Your 2026 T2 Return?
Review your corporation’s tax details before submitting its return or making instalment payments. The correct calculation depends on the corporation’s tax year, income and eligibility.
- Confirm your corporation’s tax year and taxable income.
- Verify its CCPC status and available small business limit.
- Check whether associated corporations share that limit.
- Separate active business income from passive investment income.
- Apply any provincial rate changes that fall within the tax year.
- Review eligible deductions, credits and capital cost allowance claims.
- Confirm instalment requirements and the applicable payment deadline.
- Check the T2 filing deadline, which generally falls six months after the end of the corporation’s tax year.
Most corporations must pay their balance of tax within two months after their tax year ends. Certain qualifying CCPCs can receive a three-month balance-due period. Payment deadlines and filing deadlines are separate, so check the applicable rules for your corporation.
