Most guides to filing late explain the late-filing penalty and stop there. That penalty is real, and it is also the smallest charge on the list. The expensive ones apply when a pattern builds up across several years, and there is exactly one route that closes them off.
Key takeaways
- Late filing costs 5% of the balance owing plus 1% a month, to a 12 month cap.
- A repeat, after a demand to file, doubles it to 10% plus 2% a month, to 20 months.
- File even if you cannot pay. Filing on time removes the late-filing penalty entirely, and interest alone is much cheaper.
- The larger penalties are for repeated failure to report income and for false statements, and they run to 50% in some cases.
- Relief from those depends on disclosing before the CRA contacts you.
- The disclosures programme changed on October 1, 2025. Coming forward first now triples the interest relief.
What late filing actually costs
| Situation | Penalty |
|---|---|
| Filed late, tax owing, first time | 5% of the balance owing, plus 1% of it for each full month late, up to 12 months |
| Filed late after a demand to file, and penalised in any of the three previous years | 10% of the balance owing, plus 2% for each full month late, up to 20 months |
| Corporation filing a T2 late, tax owing | 5% of the unpaid tax, plus 1% for each complete month, up to 12 months |
| Corporation, repeat, after a demand to file | 10% of the unpaid tax, plus 2% for each complete month, up to 20 months |
On top of any penalty, the CRA charges compound daily interest on an unpaid balance from the day after the due date. Interest and penalty are separate charges, and the interest rate is reset quarterly.
Six months late on a $10,000 balance, as a first offence, is 5% plus six monthly points, so 11%, or $1,100 before interest. The same six months as a repeat filer after a demand to file is 22%, or $2,200. The rate doubles and the clock runs almost twice as long.
The instruction that saves the most money
If you take one thing from this page, take this one. The late-filing penalty is charged for filing late, not for paying late. Those are two different failures with two different prices.
File on time even when you cannot pay. It removes the late-filing penalty completely. You will still owe interest on the balance, but you will not be adding a percentage point of the whole balance every month on top of it.
Waiting until the money is there before filing is the single most expensive instinct in this area, and it is extremely common. See the filing and payment deadlines for which date is which, because for many people the payment date and the filing date are not the same day.
The penalties most guides leave out
These are the ones that make a multi-year problem serious, and they are the reason a file that has been quietly ignored gets expensive rather than just annoying.
| Penalty | When it applies | How much |
|---|---|---|
| Repeated failure to report income | You failed to report $500 or more on your 2025 return, and also on your 2022, 2023 or 2024 return | A federal and a provincial or territorial penalty. The lesser of 10% of the amount you failed to report, or 50% of the difference between the understated tax or overstated credits and the tax withheld on that amount |
| False statements or omissions | A false statement or omission made knowingly, or in circumstances amounting to gross negligence | The greater of $100, or 50% of the understated tax or overstated credits |
Read those against the late-filing penalty and the proportions become clear. Filing a year late with a balance is a percentage problem. A pattern of unreported income across several years is a different category of exposure.
The line that decides which numbers apply
On both of its penalty pages, the CRA says the same thing: it may grant relief where you voluntarily disclose the amounts you failed to report, or the credits you overstated, before the CRA contacts you or anyone related to you. Both pages then point at the same place, the Voluntary Disclosures Programme.
That is the actual decision in front of anyone who is behind. Not whether to file, but whether to move before the CRA does. Everything above changes price depending on which side of that line you are on.
How the disclosures programme changed on October 1, 2025
The programme was reformed, and the changes went in the taxpayer’s favour. The application was simplified, eligibility widened, and the old streams were replaced by two relief tiers.
| Tier | Normally applies to | Interest relief | Penalty relief |
|---|---|---|---|
| General relief | Unprompted applications | 75% | 100% |
| Partial relief | Prompted applications | 25% | Up to 100% |
Penalty relief is broadly available on either tier. The interest relief is what separates them, and it triples if you come forward before the CRA raises the issue. Across several years of unfiled or misfiled returns, interest is usually the largest single figure in the whole exercise.
Eligibility also widened in a way that matters. Under the old rules a letter from the CRA about potential non-compliance generally ended the conversation. Now someone prompted by such a communication can still be eligible. Being under audit or investigation still restricts eligibility, as does having been egregiously non-compliant, so the window narrows as CRA attention increases rather than closing all at once.
If the penalties are already assessed
A separate route exists. You can ask the CRA to cancel or waive penalties and interest where circumstances beyond your control prevented you from meeting your obligations. A request can reach a 10-year period ending in the calendar year the request is made. It reaches penalties and interest, never correctly assessed tax.
If collection has already started rather than just assessment, that is a different stage with different options. See what happens when the CRA starts collecting, and what to do about a frozen bank account if it has gone that far. Where the arrears are payroll rather than income tax, payroll remittances are treated more urgently again.
Filing and paying are two different problems
Owners delay filing because they cannot pay what the return will show. That gets the order backwards, and expensively so. Filing stops the late-filing penalty, removes the failure-to-file exposure, and replaces any estimated assessment with real numbers, which are frequently lower. What the balance turns out to be is then a payment arrangement question, handled separately. For a corporation, the T2 and the instalment position usually need reconciling at the same time.
Common questions
What is the penalty for filing taxes late in Canada?
If you file after the due date and owe tax, the CRA charges 5% of the balance owing plus 1% of that balance for each full month the return is late, up to 12 months. If you were penalised in any of the three previous years and received a demand to file, it rises to 10% plus 2% per full month, up to 20 months.
Is there a penalty if I do not owe anything?
The late-filing penalty is calculated on the balance owing, so with no balance there is nothing for it to apply to. Filing still matters, because benefit and credit payments depend on your return being filed and late filing can delay them.
Should I file if I cannot pay?
Yes, and the CRA says so directly. Filing on time avoids the late-filing penalty even when the balance goes unpaid. Interest still runs on what you owe, but interest is far cheaper than interest plus a penalty that grows every month.
What is the penalty most people do not know about?
Repeated failure to report income. If you failed to report $500 or more on your 2025 return and also on your 2022, 2023 or 2024 return, a federal and a provincial or territorial penalty can apply. It is the lesser of 10% of the amount you failed to report, or 50% of the difference between the understated tax and the tax already withheld on it. That is a different order of magnitude from the late-filing penalty.
How did the Voluntary Disclosures Program change?
On October 1, 2025 the CRA simplified the application, widened eligibility, and replaced the old streams with two relief tiers. General relief, normally for unprompted applications, gives 75% relief of applicable interest and 100% of applicable penalties. Partial relief, normally for prompted applications, gives 25% of interest and up to 100% of penalties.
Can I still apply if the CRA has already written to me?
Often yes, and that is the substantive change. Someone prompted by a communication about potential non-compliance can now be eligible. Being under audit or investigation still restricts eligibility, as does having been egregiously non-compliant.
How far back can penalties and interest be cancelled?
A taxpayer relief request can reach a 10-year period ending in the calendar year the request is made. It applies to penalties and interest, not to correctly assessed tax.
What happens to my corporation if the T2 is late?
The same structure applies: 5% of the unpaid tax due on the filing deadline plus 1% for each complete month, up to 12 months. Where the CRA issued a demand to file and assessed a failure-to-file penalty in any of the three previous tax years, it becomes 10% plus 2% per complete month, up to 20 months.
