Running a successful small business in Canada means handling more than just your products and services. It also means keeping track of your tax responsibilities. For small business owners, understanding and meeting CRA deadlines is key to staying financially healthy and avoiding penalties.
Whether you’re a sole proprietor working from your home office or managing a corporation with several employees, the 2025 income tax filing season has important deadlines and rules. Missing these deadlines could result in penalties, interest charges, and could hurt your business’s cash flow and reputation with the CRA.
Self-Employed Tax Deadline for Small Businesses 2025
- Filing Deadline: June 15, 2025
- Payment Deadline: April 30, 2025
If you’re self-employed in Canada, your tax return must be filed by June 15, 2025, for the 2024 tax year. However, the deadline to pay any taxes owed is April 30, 2025.
Although you have until June 15 to file, interest begins on unpaid taxes after April 30. To avoid extra charges, it’s a good idea to treat April 30 as your real deadline and pay any owed taxes by then.
Corporation Tax Deadline for Small Businesses 2025
- Filing Deadline: Six months after your fiscal year-end
- Payment Deadline: Two months after your fiscal year-end
For incorporated businesses in Canada, the corporate tax return (T2) is due six months after your fiscal year ends.
For example, if your corporation’s fiscal year ends on December 31, 2024, the return will be due by June 30, 2025. However, the corporate tax payment is due two months after your fiscal year-end, by February 28, 2025.
If your fiscal year-end is different, adjust your deadlines accordingly to avoid penalties.
Penalties for Filing Taxes Late
If you file your small business taxes late, you will face penalties. The CRA charges a late-filing fee of 5% of the balance owed, plus 1% for each month it’s late. The penalty can go up to 12 months.
If you keep filing late within a four-year period, the penalties can rise to 10% of the owed amount, plus 2% per month.
Missing your deadlines can be costly, so it’s very important to stay on top of them.
Sales Tax Deadlines in Canada (GST/HST/QST)
The due dates for your GST/HST return depend on your sales tax reporting period, which you select when registering for your GST/HST account.
Monthly: Filing and payment are due one month after the reporting period ends.
Quarterly: Filing and payment are due one month after the reporting period ends.
Annually: Filing and payment are due three months after your fiscal year-end.
For instance, if your business files quarterly and your reporting period ends on March 31, 2025, the filing and payment deadline is April 30, 2025.
Other Key Deadlines for Small Businesses
Besides income and sales tax, there are other important dates you need to remember:
T4, T4A, and T5 Slips Deadline: If you have employees, you need to distribute and file T4, T4A, and T5 slips by February 28, 2025.
RRSP Contribution Deadline: The RRSP contribution deadline for the 2024 tax year is February 28, 2025.
TFSA Contribution Deadline: The TFSA contribution deadline for 2024 is December 31, 2024. However, any unused contribution room carries forward.
