Personal/Individual Tax Deadlines for 2025
For Sole Proprietors and Self-Employed Canadians
If you or your spouse earned business income in 2024, your personal tax return must be filed by June 16, 2025. The standard June 15 deadline is extended by one business day this year because it falls on a Sunday.
However, keep in mind that any personal taxes due must still be paid by April 30, 2025. Filing after this date, even if the return filing date is later, can lead to interest charges and penalties. It’s always a good idea to file early to avoid last-minute complications. Planning ahead ensures smoother financial operations throughout the year.
For Non-Self-Employed Canadians
If you don’t have self-employment income, your tax return and any taxes owed are due by April 30, 2025. This is the most common filing scenario for individuals and ensures your finances are squared away before summer starts. Filing on time also allows you to focus on future financial planning without the weight of overdue obligations.
Tax Installments for 2025
If you’re required to pay taxes in installments, here are the critical dates for 2025:
- March 15, 2025
- June 15, 2025
- September 15, 2025
- December 15, 2025
Installments help you spread out your tax obligations over the year, reducing the burden of a single large payment. Missing these deadlines can result in interest charges, so consider setting reminders or automating payments for added convenience. Automating payments also ensures you stay compliant with tax obligations without added administrative burden.
RRSP Contribution Deadline for 2024 Tax Deductions
To reduce your 2024 tax bill, you have until March 3, 2025, to contribute to your RRSP. Planning ahead is essential, as last-minute contributions can sometimes face delays due to administrative processing. Contributing early not only secures your deduction but also allows your investments more time to grow tax-free. Starting early helps you maximize your long-term financial strategy and ensure timely contributions.
Corporate Tax Deadlines in 2025
Corporate Tax Returns
Corporations must file their corporate income tax return within six months of their fiscal year-end. Here are some examples to clarify the deadlines:
- If your fiscal year ends on December 31, 2024, your return is due by June 30, 2025.
- If your fiscal year ends on March 31, 2025, your return is due by September 30, 2025.
By filing on time, you avoid penalties and maintain good standing with the CRA, which is essential for future financial planning and funding opportunities. Filing promptly also provides more time to focus on strategic business objectives and operational improvements.
Corporate Taxes Owing
Corporate taxes owed are generally due two months after the fiscal year-end. However, Canadian Controlled Private Corporations (CCPCs) that qualify for the small business deduction have an extra month, making their tax amount owing due three months after the fiscal year-end.
For example, if a CCPC’s fiscal year ends on December 31, 2024, taxes would be due by March 31, 2025, instead of the usual two-month deadline. Double-check your corporation’s eligibility to ensure you meet the correct deadlines. For detailed guidelines, visit the Corporate Tax Filing Guide.
T4A and T5018 Slips Deadline
If your business makes payments to individuals or subcontractors, you may need to file:
- T4A slips for payments to self-employed individuals.
- T5018 slips for payments to subcontractors in the construction industry.
Both types of slips must be filed with the CRA and provided to recipients by February 28, 2025. For more details on T4A filing requirements, visit the Canada Revenue Agency website. Failing to file these slips on time can lead to penalties, so it’s vital to organize your financial records early in the accounting period. Early preparation reduces stress and ensures timely compliance.
GST/HST Deadlines for Businesses
Monthly Filers
If you file GST/HST returns monthly, your due date is one month after the reporting period ends. Learn more about GST/HST filing requirements on the Government of Canada’s GST/HST guide.
Example: The January 2025 reporting period is due by February 28, 2025. Filing monthly helps distribute your workload and ensures your tax obligations are met regularly. Consistent filings also allow for better financial tracking and forecasting.
Quarterly Filers
Quarterly filers must submit their GST/HST returns and payments one month after the end of the reporting period.
Example: For the reporting period January to March 2025, the filing due date is April 30, 2025. Quarterly filings strike a balance between frequent updates and manageable reporting periods, ensuring smoother operations for businesses.
Annual Filers (Excluding Individuals With December 31 Year-Ends)
For businesses with non-calendar fiscal years, annual GST/HST returns and payments are due three months after the reporting period ends.
Example: If the reporting period is July 1, 2024, to June 30, 2025, the deadline is September 30, 2025. Annual filing requires careful record-keeping throughout the year to ensure accuracy. Accurate record-keeping supports long-term compliance and financial stability.
Annual Filers (Individuals With December 31 Year-Ends)
For self-employed individuals filing annually:
- GST/HST owing is due by April 30, 2025.
- GST/HST return filing is due by June 16, 2025, extended because June 15 falls on a Sunday.
Timely filings and payments prevent interest charges and ensure compliance with tax regulations. Early submissions also give you peace of mind as you plan for future fiscal periods.
