What is Corporate Tax?
Corporate tax is a type of tax that businesses pay on their profits. The government uses this money to fund public services like healthcare, education, and infrastructure. In Canada, both federal and provincial governments charge corporate taxes.
Federal Corporate Tax Rates in Canada
The federal government sets a base tax rate for all corporations in Canada. As of 2025, the general federal corporate tax rate is 15%. However, small businesses that qualify for the small business deduction pay a lower rate of 9%.
To qualify as a small business, your company must be a Canadian-controlled private corporation (CCPC) and earn less than a certain amount of active business income. The limit changes yearly, so checking the latest rules is important.
Provincial Corporate Tax Rates in Canada
In addition to federal taxes, each province and territory in Canada has its corporate tax rates. These rates vary depending on where your business operates. Here is a simple breakdown of provincial tax rates for 2025.
Alberta has a general corporate tax rate of 8% and a small business tax rate of 2%. British Columbia charges 12% for general corporations and 2% for small businesses. Manitoba offers a 12% general rate and 0% for small businesses on the first $500,000 of income.
New Brunswick applies a 14% general rate and 2.5% for small businesses. Newfoundland and Labrador have a 15% general rate and 3% for small businesses. The Northwest Territories charge 11.5% for general corporations and 4% for small businesses.
Nova Scotia’s general rate is 14%, with a 2.5% small business rate. Nunavut has a 12% general rate and 3% for small businesses. Ontario’s general rate is 11.5%, and small businesses pay 3.2%.
Prince Edward Island has a 16% general rate and 1% for small businesses. Quebec charges 11.5% for general corporations and 4.5% for small businesses. Saskatchewan applies a 12% general rate and 1% for small businesses. Yukon has a 12% general rate and 2% for small businesses.
Combined Federal and Provincial Tax Rates
Since businesses pay both federal and provincial taxes, the total corporate tax rate is the sum of both. For example, if your business is in Ontario, the general corporate tax rate is 11.5% provincial plus 15% federal, totaling 26.5%. A small business in Ontario pays 3.2% provincial plus 9% federal, totaling 12.2%.
This means a small business in Ontario pays 12.2% tax on its first $500,000 of income, while larger corporations pay 26.5%.
Tax Credits and Deductions
The Canadian government offers several tax credits and deductions to help businesses reduce their tax burden. Some common ones include the Scientific Research and Experimental Development (SR&ED) Tax Credit, which encourages businesses to invest in research and development. Companies can claim a portion of their R&D expenses as a tax credit.
The Small Business Deduction allows small businesses to pay a lower tax rate on their first $500,000 of income. This helps startups and small companies grow. The Capital Cost Allowance (CCA) lets businesses deduct the cost of assets like equipment, vehicles, and buildings over time through depreciation.
Many provinces offer additional tax credits for hiring employees, investing in green energy, or operating in specific industries.
How to File Corporate Taxes in Canada
Filing corporate taxes involves several steps. First, determine your fiscal year. Unlike personal taxes, businesses can choose their fiscal year-end. Most companies use December 31, but you can pick any date.
Next, prepare financial statements. You need accurate financial records, including income statements, balance sheets, and expense reports. Then, calculate taxable income by subtracting allowable expenses from your total revenue.
After that, complete the T2 Corporation Income Tax Return. All corporations in Canada must file a T2 return, even if they have no tax payable. Finally, pay any taxes owed by the deadline to avoid penalties.
Common Mistakes to Avoid
Many business owners make mistakes when filing corporate taxes. One common error is missing deadlines, which can result in penalties and interest charges. Another mistake is not keeping proper records, making it difficult to claim deductions.
Some businesses also fail to take advantage of available tax credits, paying more tax than necessary. Others mix personal and business expenses, which can lead to problems during audits.
Tips for Reducing Corporate Tax
There are several ways to reduce your corporate tax bill. One effective strategy is to maximize deductions by claiming all eligible business expenses. Another is to take advantage of tax credits like SR&ED or provincial incentives.
Incorporating your business can also provide tax benefits, as corporate tax rates are often lower than personal tax rates for high-income earners. Additionally, strategically planning your fiscal year-end can help defer taxes.
Conclusion
Understanding corporate tax rates in Canada is crucial for managing your business finances effectively. Knowing the federal and provincial rates, taking advantage of deductions, and avoiding common mistakes can minimize your tax burden and keep more of your profits.For more detailed information, check out this blog: How Does Corporate Tax Work in Canada?
