If you can’t pay your tax bill in full, file your return on time anyway and call the CRA before the debt grows. Filing on time avoids the late-filing penalty, and an early call can get you a payment arrangement, which lets you pay in smaller amounts until the debt and its interest are cleared. The interest clock runs either way, at 7% a year for October to December 2026.
What should you do first?
File. It sounds backwards when you’ve got no money, but the CRA says that if you can’t pay your balance by the due date, filing on time avoids the late-filing penalty. The penalty for filing late is far bigger than the interest on a small unpaid balance.
Then contact the CRA. Its own advice is that acting early can cut extra interest, costly penalties and collection action. You can do that in My Account.
How does a payment arrangement work?
You agree to pay the debt in smaller pieces over time. If your personal income tax debt is $1,000 or more, the Manage balance service in My Account lets you make a full or partial payment, schedule a series of payments, ask for a callback or contact a collections officer without waiting on a phone line. Smaller debts, or business ones, go through other CRA channels, and we couldn’t confirm the exact steps for them.
We also couldn’t find a rule on how long an arrangement can run. Ask for the term in writing and check that the payments fit your budget. Skipping one can bring the collection steps back.
What does an unpaid tax bill really cost?
Interest, and it compounds daily. The rate on overdue tax is 7% for the fourth quarter of 2026, and it moves with each quarter. On a $3,000 balance, that comes to about $217.50 over a full year with daily compounding. Late filing adds a penalty of 5% of the balance owing plus 1% for each full month late, up to 12 months. On $3,000 filed three months late, that’s $240.
Anyone hit with the penalty in one of the last three years faces double: 10% plus 2% a month, up to 20 months.
| On a $3,000 balance | Amount |
|---|---|
| Interest for a year at 7%, compounded daily | about $217.50 |
| Late-filing penalty, 3 full months late | $240 |
| Repeat late-filing penalty, 3 full months late | $360 |
| 12 monthly payments to clear it at 7%, our loan maths | $259.58 each |
That last line is our own loan formula, not a CRA schedule, and total interest comes to about $115. The CRA works out its own figures, so treat ours as a guide. The personal loan calculator lets you test other terms.
How do you fit the payments into your budget?
Start with what actually leaves your account each month, not what you think does. Rent or mortgage, groceries, the phone bill, the car. Whatever is left is what you can offer the CRA, and it’s better to offer a number you can keep than a bigger one you’ll miss in month three.
Take Amir in Regina, who owed $3,000 and could spare about $260 a month. That matched the 12-payment line in the table above almost to the dollar. Knowing that figure before he called made the conversation short and calm.
Can’t find the room? Look at the small stuff first. Three bucks a day on takeout coffee is about $90 a month, and that alone covers a third of the payment.
Can the CRA cancel penalties or interest?
Sometimes. Form RC4288 asks the CRA to cancel or waive penalties and interest, and requests are accepted within 10 calendar years of the tax year, under the CRA’s taxpayer relief provisions. It’s a request, not a right. Explain what happened and attach proof, since the CRA decides case by case. We couldn’t confirm any list of accepted reasons, so read the form before you rely on it.
What if you ignore it?
The CRA says your benefit and credit payments or tax refunds could be withheld and applied to the debt, or legal action could start. That’s the outcome to avoid. A payment of even a modest size, made on a plan you agreed, beats silence.
To see where next year’s bill could come from, the tax instalments calculator shows what to set aside during the year. The tax refund calculator gives an early warning when a balance owing is coming, and the budget calculator shows the monthly amount you can afford.
