What happens if you don't file your taxes in Canada?
Penalties, interest, paused benefits and CRA collections: what skipping a tax return can cost you, and how to get back on track.

In short
- Most Canadians need to file a return every year, even with little or no income.
- If you owe tax and file late, the penalty starts at 5% of what you owe and grows each month.
- Interest on unpaid tax compounds daily from May 1.
- Not filing can pause benefits such as the Canada Child Benefit and the GST/HST credit.
- The CRA can collect directly from your pay, your bank account or your refunds.
- It is never too late to catch up, and the sooner you do, the less it costs.
How tax filing works
Canada's tax year follows the calendar, January 1 to December 31. Your personal return for the year is due on April 30 of the following year. If you or your spouse or common-law partner are self-employed, you have until June 15 to file, but any balance owing is still due on April 30.
Your return tells the Canada Revenue Agency (CRA) what you earned, what you have already paid through payroll deductions or instalments, and which deductions and credits you qualify for. The CRA then sends a notice of assessment confirming whether you owe money or are getting a refund. Most people file online with CRA-certified software, through a tax professional, or on paper.
Who has to file?
You need to file a return for the year if any of these apply to you:
- You owe tax, for example because not enough was withheld from your pay.
- You earned self-employment, rental, investment or other income that has to be reported.
- You sold property, shares or other investments, or have to repay benefits such as Old Age Security or EI.
- The CRA has sent you a request to file.
- You want a refund, or want to receive benefits and credits such as the Canada Child Benefit (CCB), the GST/HST credit or the Guaranteed Income Supplement.
Newcomers, international students and temporary workers who are residents for tax purposes have the same obligations. And even if you earned nothing, filing is usually worth it, because the CRA uses your return to work out the benefits you're entitled to.
What is the basic personal amount?
The basic personal amount is the income you can earn before you pay any federal income tax. For 2026 it is up to $16,452, and it is gradually reduced for very high earners. Each province and territory sets its own amount on top of this. Earning less than the basic personal amount doesn't always mean you can skip filing, since you may still need a return to claim benefits.
What happens if you don't file?
Late-filing penalties
If you owe tax and miss the deadline, the CRA adds a penalty of 5% of the balance owing, plus 1% for each full month the return is late, up to 12 months. If you were charged a late-filing penalty in any of the three previous years and the CRA had asked you to file, the penalty doubles to 10% of the balance plus 2% a month, for up to 20 months. If you're owed a refund, there is no penalty for filing late, but you won't see the money until you file.
Interest that compounds daily
Interest on any unpaid balance starts on May 1 and compounds every day. The CRA sets its rate each quarter. Interest is also charged on top of any penalties, so a small balance can grow quickly. Filing on time, even if you can't pay in full, keeps the penalty off the table and limits the damage to interest.
Paused benefits and credits
Many government payments are based on your tax return. If you don't file, payments such as the Canada Child Benefit, the GST/HST credit and the Guaranteed Income Supplement can be delayed or stopped until you do. For families, this is often the most expensive part of not filing.
CRA collections
When a tax debt goes unpaid, the CRA has strong tools to collect it. It can:
- Require your employer or bank to send part of your pay or account balance directly to the CRA.
- Keep future refunds and benefit payments to cover what you owe.
- Register a lien against your home or other property.
What if you haven't filed for several years?
The longer returns go unfiled, the more penalties and interest pile up. The CRA can also estimate your income and issue an assessment based on its own figures, which can be higher than what you actually owe. Once that assessment is issued, you can still file the real return to correct it, but it is better to get ahead of it.
What if there was a mistake on a past return?
You can ask the CRA to change a return you've already filed. If you left out income or made a mistake on purpose or by accident and the CRA hasn't contacted you about it yet, the Voluntary Disclosures Program lets you come forward on your own. If your application is accepted, the CRA may cancel some or all of the penalties and reduce the interest you would otherwise pay.
Can you go to jail for not filing?
It's rare. Almost all cases end with penalties and interest. Deliberate tax evasion is different: it is a criminal offence, and a conviction can bring fines of up to twice the tax evaded and, in serious cases, a prison sentence. Simply being late or disorganized is not tax evasion, but ignoring the CRA's requests for years can escalate.
How long should you keep your records?
The CRA generally asks you to keep your tax records and receipts for six years from the end of the tax year they relate to. Keeping them for seven years gives you an extra margin.
How to get back on track
If you've fallen behind, the fix is the same however many years it's been:
- Gather what you have. Your slips are available in CRA My Account, even for past years. Our tax season checklist lists what else to pull together.
- File the most recent year first, so current benefits can restart, then work back through older years.
- Talk to the CRA early if you can't pay in full. Payment arrangements are available, and filing on time still saves you the late-filing penalty.
- Get help. A tax professional can file several years at once and tell you whether the Voluntary Disclosures Program makes sense. If your income is modest, free tax clinics run through the CRA's Community Volunteer Income Tax Program may also help.
