When it comes to taxes, timing is everything. Filing your taxes on time—and knowing the critical deadlines—can help you avoid penalties, interest, or the stress of last-minute scrambling. Whether you’re self-employed, a salaried employee, or somewhere in between, staying on top of these dates is essential. So, when exactly should you file your taxes in Calgary? Let’s break it all down with nine key tax deadlines for 2025 that every Calgarian should mark on their calendar.
1. January 1, 2025 – The Clock Starts for RRSP Contributions
Here’s some good news to kick off the year: You have until early March 2025 to contribute to your Registered Retirement Savings Plan (RRSP) and still claim it on your 2024 tax return. Contributions made from January 1 to March 2, 2025, can be applied to either 2024 or 2025, depending on what works best for you.
Why does this matter? RRSP contributions are one of the most effective ways to reduce your taxable income. Plus, the earlier you make the contribution, the more time your money has to grow tax-free.
2. February 28, 2025 – T4s and Other Tax Slips Are Due
By the end of February, your employer is legally required to provide you with your T4 slip, which summarizes your income and tax deductions for the previous year. If you work multiple jobs, ensure you’ve received all your T4s before filing your taxes.
Other important tax slips, like T5s (investment income) or T4A (self-employment income), are also due around this time. Keep an eye on your mailbox or your email inbox, as many companies are now switching to digital delivery.
3. March 2, 2025 – Final Day for RRSP Contributions
This is your absolute last chance to contribute to your RRSP for the 2024 tax year. If you’re looking to maximize your tax savings, consider making a lump-sum contribution before this deadline.
If you’re unsure how much room you have left to contribute, check your most recent Notice of Assessment (NOA) from the Canada Revenue Agency (CRA). It will outline your remaining RRSP contribution limit.
4. April 30, 2025 – Personal Tax Filing Deadline
Circle this date in bold! For most Canadians, April 30 is the final day to file your personal income tax return for the 2024 tax year. If you owe money to the CRA, you must also pay your balance by this date to avoid late penalties and interest charges.
If you’re expecting a refund, filing early can speed up how quickly you get your money. For those who qualify for benefits like the Canada Child Benefit or GST/HST Credit, filing on time ensures your payments aren’t delayed.
5. June 15, 2025 – Tax Deadline for Self-Employed Individuals
Are you self-employed or a small business owner in Calgary? The CRA gives you until June 15 to file your tax return. However, there’s a catch: If you owe taxes, the CRA still expects you to pay your balance by April 30. Waiting until June to file without paying could result in interest charges, so it’s best to estimate and pay what you owe by the earlier deadline.
If you run a home-based business, this is also a good time to gather receipts for expenses like utilities, internet, and office supplies. These deductions can significantly lower your taxable income.
6. June 30, 2025 – Corporate Tax Deadline for December Year-End
Do you own a corporation in Calgary with a December 31 fiscal year-end? If so, June 30 is your filing deadline for 2024 corporate taxes. This is your chance to report your business’s income, expenses, and deductions.
Corporate taxes can be more complex than personal taxes, so consider working with an accountant to ensure accuracy and avoid costly mistakes.
7. September 15, 2025 – Quarterly Tax Installment for Self-Employed
If you’re self-employed or earn income that isn’t subject to payroll tax deductions, you may need to make quarterly tax installments. The September 15 installment is one of four deadlines throughout the year (the others fall in March, June, and December).
Not sure if this applies to you? Check your CRA account or your previous tax return to see if you’ve been asked to pay installments. Missing these deadlines can result in interest charges, so it’s crucial to plan ahead.
8. December 15, 2025 – Final Quarterly Installment
The last quarterly installment for self-employed individuals or those with significant investment income is due on December 15. Paying this on time ensures you’re not caught off guard by a large tax bill come April.
This is also a good time to check your finances and make any charitable donations, as these contributions can boost your tax refund for the following year.
9. Anytime in February to April – The Best Time to File
Wondering when exactly you should file your taxes? While the deadline for most people is April 30, filing earlier has its perks. If you’re expecting a refund, filing in February or early March means you’ll likely see that money sooner. It’s also a smart move to avoid the April rush, which can overwhelm online filing systems and tax preparers.
For those who owe taxes, filing early gives you time to budget for the payment, even if you wait until April 30 to pay.
