Let’s get you and your business ready for a smooth tax season this 2025!
In this article, we’ll go over all the important tax deadlines for small businesses in Canada you need to know about, whether you’re self-employed or a corporation.
Self-Employed Tax Deadline for Small Business 2025
June 15th, 2025, but the payment is due on April 30, 2025.
If you're self-employed in Canada, the tax deadline for filing your income tax return is June 15th, 2025, for the 2024 tax year.
However, the payment deadline is still due no later than April 30, 2025, to avoid interest charges.
Due to this, we recommend considering April 30 as your actual deadline.
Corporation Tax Deadline for Small Business 2025
6 months after your fiscal year-end, but the payment is due 2 months after.
When is your corporate tax filing due? For incorporated businesses in Canada, the tax deadline is 6 months after on your fiscal year-end.
For example, if your corporation's fiscal year ends on December 31, 2024 (this is the case for most), your corporate tax return (T2) is due six months after that, which would be June 30, 2025.
However, your payment is due only 2 months after the fiscal year ends. Due to this, we recommend considering 2 months after year-end as your actual deadline.
If your fiscal year-end is different, you’ll have to adjust your deadlines accordingly.
What Is the Penalty For Filing Taxes Late?
5% of the balance owing + 1% each month
Filing taxes late for a small business can result in penalties and interest charges. The penalties can be significant and are calculated based on the amount owing and the number of days your return is late. For instance, the late-filing penalty is 5% of the balance owing, plus an additional 1% of the balance owing for each full month your return is late, up to a maximum of 12 months.
Sales Tax Deadlines in Canada
Your corporate GST/HST/QST return deadline depends on your business’ specific reporting period.
The options are:
Monthly reporting period: Your sales tax filing and payment are due one month after the end of your reporting period.
Quarterly reporting period: Your sales tax filing and payment are due one month after the end of your reporting period.
Annual reporting period: Your sales tax filing and payment are due 3 months after your fiscal year-end.
Where Can I Find My Sales Tax Reporting Period?
When you first set up your sales tax account, you have the chance to select your preferred filing period. If your business is earning under $1.5 million per year, quarterly filing will be your default.
You can double check your reporting period in your CRA business account. If you can’t find your sales tax reporting period, contact the CRA at 1-800-959-5525.
Other Important Deadlines for Small Businesses
A few other important deadlines that you might want to know about:
