2025 Canadian Corporate Tax Rates and Filing Deadlines
Understanding your corporate tax rates can help you plan better and keep more of your hard-earned money. Learn about small business deductions and filing deadlines.
- CCPCs get lower tax rates through the Small Business Deduction
- First $500,000 of active business income qualifies for reduced rates
- T2 returns are due 6 months after your fiscal year-end
- Minute books are a legal requirement for all corporations
Why Corporate Tax Rates Matter
One of the biggest advantages of incorporating your business is access to lower tax rates. Canadian-Controlled Private Corporations (CCPCs) can benefit from the small business deduction, which significantly reduces the federal tax rate on the first $500,000 of active business income.
Key Points About Corporate Tax Rates
- The small business tax rate applies to the first $500,000 of active business income
- Passive investment income over $50,000 can reduce your small business deduction eligibility
- Combined federal and provincial rates vary by province—check rates for BC, Alberta, or your specific location
- Tax planning throughout the year can help minimize your overall burden
Passive investment income over $50,000 in your corporation can reduce or eliminate your small business deduction eligibility.
Filing Deadlines for Corporations
Unlike personal tax returns with a fixed April 30 deadline, corporate filing deadlines depend on your fiscal year-end. Your T2 corporate tax return is due six months after your tax year ends.
Don't Forget Your Minute Books
While not part of your tax filing, minute books are a legal requirement for all corporations under the Canada Business Corporations Act. Keep them updated with board meeting minutes and major financial transactions.
