Did you know? If you file your taxes late in Canada, the Canada Revenue Agency (CRA) charges a penalty of 5% of your unpaid taxes right off the bat. If you want to avoid hefty fines keep on reading.
Well, let’s talk about what happens when you’re filing taxes late in Canada in 2025 and what kind of hit your wallet might take. Follow our tips to avoid penalties for late tax filing in Canada
What Happens If You Miss the Tax Deadline?
Missing the deadline means you’re now facing the late filing penalty from CRA enforced every year.
Here’s what happens:
- You owe 5% of your unpaid taxes right away.
- Then, add 1% for every month you’re late, up to 12 months.
- If you were also late in the past three years, the penalty jumps to 10% of the balance you owe, plus 2% per month for each full month you file after the due date. This additional 2% can be charged up to a maximum of 20 months.
So yeah, penalties for late filing of tax return can add up. And don’t forget the interest. CRA charges daily compound interest on top of it all.

But What If I Don’t Owe Anything?
If you don’t owe taxes, the CRA does not charge a late-filing penalty. The penalty only applies when you have a balance owing and miss the deadline.
But here’s the thing—what if you’re wrong and you do owe something? If you guessed wrong, you’ll still get hit with the penalty for late tax filing plus interest. It’s a bit of a gamble.
Also, even if you don’t owe, you might be leaving money on the table. Benefits like GST/HST credits or the Canada Child Benefit require you to file on time. No return, no payment.
Penalty for Late Tax Filing with Interest

So you missed the deadline. You now owe a penalty for filing taxes late. But wait—there’s more! You’ll also pay interest on what you owe. The CRA charges daily interest starting the day after the due date. And it adds up fast.
So, not only are you getting the late filing penalty, but you’re also paying interest on your unpaid taxes and your penalty. That’s a rough combo.
CRA Updates in 2025 You Should Know

Now, 2025 is a little different. The CRA has made some changes in 2025. For folks who have to report capital gains, you get a bit of breathing room. If you’re an individual and you’re reporting capital gains, the CRA is giving you until June 2, 2025. That’s an extension without the penalty for late tax filing or interest.
If you’re a trust reporting capital gains, you have until May 1, 2025.
That said, don’t take this as a free pass. These exceptions are pretty specific. If your situation doesn’t fall under these categories, you’re still looking at that classic penalty for late tax return.
Step-by-Step Guide: What To Do If You Get Penalty for Late Tax Filing
So you missed the deadline. What now? Don’t stress—here’s a plan:
1. File ASAP
Even if you can’t pay yet, file your return right away. You’ll avoid that 5%–10% penalty getting worse by the month. Submitting now stops the bleeding.
2. Figure Out What You Owe
Use the CRA’s online account to check your balance. Or if you want to estimate it, use an online penalty calculator. These tools give you a quick ballpark of what you’ll pay in CRA penalties on late filing and interest.
3. Set Up a Payment Plan
Can’t pay the full amount? No biggie. CRA offers payment arrangements. File first, then contact them to set it up. It’s way better than ignoring the bill.
4. Request Relief If You Have a Good Reason
If you were sick, lost your job, or had a death in the family—ask CRA for relief. You might qualify to get the fine for late tax return or interest waived.
5. Talk to a Pro

Proactive Tips: How to Avoid Penalty for Late Tax Filing
Let’s be honest—no one wants to go through this again. Here’s how to stay ahead of the game next time:

Apply for Waiver Timely
Sometimes, life happens. You lose your job. You get sick. You’re just overwhelmed. If something outside your control caused the delay, the CRA might cut you some slack. There’s a program where you can ask them to cancel or waive the fine for filing taxes late or interest.
You’ll need to explain your situation and show proof. They don’t approve everyone, but if you’ve got a good reason, it’s worth a shot.
Why People File Late
Let’s be real for a second. A lot of us don’t file on time just because we forget. Or we’re scared we’ll owe money we don’t have. Or we just keep putting it off.
But filing taxes late in Canada doesn’t make things go away. It actually makes things worse. The CRA is more likely to work with you if you file and then talk to them about how to pay. Avoiding them? That’s what gets you those scary letters and bigger bills.
Payment Plans Exist
Can’t pay what you owe? The CRA lets you set up a payment plan. That way, you’re not buried in interest and CRA penalties on late filing. You just need to file your return and reach out.
Seriously, don’t let fear stop you from filing. You have more options when you’re honest and upfront.
Reminder: File Even If You Can’t Pay
This one’s important. Even if you can’t pay your taxes, FILE THEM. Why? Because filing late is what triggers the big penalty for late tax filing. If you file on time but can’t pay right away, you only deal with interest. That’s way better than a double-whammy of interest plus a fine for late tax return.
Don’t Forget About Repeated Offenders
If you’re late over and over again, the CRA will not take it easy on you. This is called a repeated failure to report income. You can get hit with even more CRA penalties on late filing, especially if they think you’re trying to dodge taxes.
It’s not just about being late. It’s about whether they believe it’s becoming a pattern. Don’t get labeled that way. It’s hard to undo.
Last-Minute Tips
If you’re close to the deadline, don’t wait! File online. It’s fast. And you get confirmation it went through. Even if you don’t have all your slips, file something. You can always make changes later.
Filing something is better than submitting taxes late and getting stuck with a late tax return fine.
