Navigating tax season in Canada can be overwhelming, especially for business owners and accounting professionals who manage multiple filings. Staying ahead of key tax deadlines ensures compliance with the Canada Revenue Agency (CRA) and helps avoid penalties and interest charges.
In this guide, we’ll break down the most crucial Canada tax deadlines for 2025, covering personal taxes, corporate taxes, GST/HST payments, and important considerations for accountants and business owners.
Key Tax Deadlines for Individuals in Canada – 2025
For individuals, including self-employed professionals, tax season comes with specific deadlines for filing and payment obligations.
Personal Income Tax Filing Deadline: April 30, 2025
If you earned income in 2024, you must file your T1 personal income tax return by April 30, 2025.
This applies to salaried employees, freelancers, and retirees.
Filing late may result in penalties and interest charges if you owe taxes.
Self-Employed Tax Deadline: June 15, 2025
If you are self-employed or have a sole proprietorship, you have until June 15, 2025, to file your return.
However, if you owe taxes, your payment is still due by April 30, 2025—so it’s best to plan accordingly.
RRSP Contribution Deadline: March 1, 2025
If you plan to reduce your taxable income, you can contribute to your Registered Retirement Savings Plan (RRSP) until March 1, 2025 and apply it to your 2024 income.
Corporate Tax Deadlines in Canada – 2025
For businesses operating as corporations, tax deadlines vary based on your fiscal year-end.
Corporate Tax Filing Deadline: Six Months After Fiscal Year-End
Corporations must file their T2 Corporate Tax Return within six months after their fiscal year-end.
Example: If your business's year-end is December 31, 2024, your corporate tax return is due by June 30, 2025.
Corporate Tax Payment Deadline: Two Months After Fiscal Year-End
If your corporation owes taxes, payments must be made within two months of the fiscal year-end.
Example: If your business has a December 31, 2024, year-end, the tax payment is due by February 28, 2025.
Small Business Tax Payment Extension: Three Months
Canadian-controlled private corporations (CCPCs) may qualify for an extended three-month tax payment deadline if their taxable income is under $500,000.
GST/HST Filing and Payment Deadlines
If your business collects GST/HST, you must file and remit taxes on time. The deadline depends on your reporting frequency:
Monthly and Quarterly Filers
Due: One month after the reporting period ends.
Example: If you file quarterly and your period ends on March 31, 2025, your GST/HST return and payment are due by April 30, 2025.
Annual Filers (Without Monthly/Quarterly Installments)
Due: March 31, 2025, for businesses with a December 31, 2024, fiscal year-end.
Payroll Tax Deadlines: Employers Must Know
Businesses with employees must deduct and remit payroll taxes on a regular basis to avoid penalties.
Source Deduction Remittance Deadlines
If you pay employees, you must deduct CPP, EI, and income tax and remit them to the CRA.
Due dates depend on the remitter category:
Quarterly remitters: 15th of the month after the quarter ends.
Regular remitters: 15th of the following month.
Accelerated remitters: Either 3rd or 10th of the following month, depending on payroll size.
T4 and T5 Slips Deadline: February 28, 2025
Employers must issue T4 slips (employment income) and T5 slips (investment income) to employees and the CRA by February 28, 2025.
Tax Extensions and Late Filing Penalties
Filing taxes late can result in penalties and interest charges, making it crucial for businesses and individuals to stay on track.
What Happens If You File Late?
A 5% late filing penalty plus 1% per month for up to 12 months applies if you owe taxes and file late.
Interest on unpaid balances accrues daily starting May 1, 2025.
Requesting a Tax Extension
In certain cases, businesses and individuals may apply for taxpayer relief due to exceptional circumstances, such as serious illness, financial hardship, or natural disasters.
How Business Owners and Accountants Can Stay Ahead
1. Use Accounting Software
Automating tax calculations and deadlines using QuickBooks, Xero, or FreshBooks can eliminate human error and keep records organized.
2. Set Calendar Reminders
Adding key Canada tax deadlines to a Google Calendar or Outlook ensures no deadlines are missed.
3. Work With a Professional Accountant
Tax professionals can help optimize deductions, claim benefits, and ensure compliance with the latest CRA updates.
4. File Early to Avoid Processing Delays
Filing early can prevent delays in receiving tax refunds and reduce last-minute stress.
CRA online services experience high traffic in April, leading to potential slowdowns.
Final Thoughts
For businesses, self-employed professionals, and accountants, staying informed about the Canada tax deadline schedule is critical for financial success and compliance. Whether you're filing personal taxes, corporate taxes, or managing payroll, meeting these deadlines will save you from unnecessary penalties and ensure smooth operations.
