Haven’t Filed Taxes in Years? How to Catch Up With CRA
Two years behind, or ten. Either way you can still file, and nothing in the process requires you to explain why you stopped. Of the personal returns the Canada Revenue Agency (CRA) assessed between February 7 and September 8, 2026, 19,055,170 came back as refunds, averaging $2,000 (CRA, 2026). CRA updates that page through the season, so the count moves. Filing is more often a payday than a bill.
There is a real deadline here, and it is not the one people worry about. CRA will only refund you for the previous ten tax years, so every year you wait, one more year of your own money falls off the back of that window. Our personal tax return service in North York handles multi-year catch-ups regularly.
Bottom Line Up Front
- You can file for any year you missed. Tax years 2018 through 2025 go in electronically through NETFILE; older years go in on paper (CRA, 2026).
- CRA will only issue a refund or adjust a return within 10 years of the end of the tax year (CRA, 2026). In September 2026, the oldest year still open is 2016, and it closes December 31, 2026.
- The late-filing penalty is a percentage of what you owe, so if you are owed a refund, the penalty is zero (CRA, 2025).
- The bigger cost is usually lost benefits. The Canada Child Benefit, the Canada Groceries and Essentials Benefit, the Canada Workers Benefit, the Guaranteed Income Supplement and provincial programs all stop when you stop filing.
- The Voluntary Disclosures Program can remove penalties and part of the interest, but only if you apply before CRA contacts you about the specific problem (CRA, 2026).

How far back can you file, and how far back will CRA pay you?
Two different questions, two different answers. Mixing them up causes most of the confusion.
Filing: any year you missed. CRA’s Non-Filer Program exists to contact people with outstanding returns and get them filed (CRA, 2026). Tax years 2018 through 2025 go in through NETFILE, and anything older is a paper return mailed to your tax centre (CRA, 2026).
Getting paid: this is where ten years matters. Subsection 164(1.5) of the Income Tax Act lets CRA refund an overpayment even when the return arrives more than three years after the year ended, provided the return is filed inside the 10-year limit. Subsection 152(4.2) works the same way for adjustments to a return you already filed (CRA, 2026).
The window runs from the end of the calendar year the tax year fell in. CRA puts it plainly in its own reminders: requests relating to 2014 had to arrive by December 31, 2024 (CRA, 2024).
| Reading this in | Oldest year still refundable | Closes |
|---|---|---|
| 2026 | 2016 | December 31, 2026 |
| 2027 | 2017 | December 31, 2027 |
| 2028 | 2018 | December 31, 2028 |
If any of your unfiled years go back to 2016, do that one before the calendar turns.
The real cost of not filing is the benefits
Most people assume the damage is penalties. For anyone on a low or interrupted income, it is almost always the benefit payments that quietly stopped. CRA is direct about it: “Even if you do not owe tax, are tax-exempt, or have no income to report, you should do your taxes every year,” because filing “is a requirement to continue to get the benefit and credit payments you are entitled to” (CRA, 2026).
| Benefit | What filing has to do with it | Source |
|---|---|---|
| Canada Child Benefit (CCB) | File every year to keep it, even with no income, and your spouse or partner must file too. “Your payments will stop if you don’t do your taxes.” | CRA, 2026 |
| Canada Groceries and Essentials Benefit (CGEB), the renamed GST/HST credit | No application. “All you have to do is file your tax return every year, even if you do not have any income to report.” | CRA, 2026 |
| Canada Workers Benefit (CWB) | A refundable credit claimed on line 45300 of the return itself. No return, no claim. | CRA, 2026 |
| Guaranteed Income Supplement (GIS) | Renewed automatically off your return. “You must file your taxes by April 30 every year to avoid any disruption of payments.” | Service Canada, 2026 |
| Provincial and territorial programs | Administered by CRA off the same return data. | CRA, 2026 |
The GST/HST credit was renamed the Canada Groceries and Essentials Benefit in July 2026 (CRA, 2026). For the older years you are catching up on, those payments were issued under the GST/HST credit name.
Stack four years of CCB for two children against four years of penalties on a small balance and the arithmetic is rarely close. Our breakdown of how the Canada Workers Benefit works covers what you would be claiming back on that one.
Penalties and interest, in plain numbers
The late-filing penalty is 5% of your balance owing, plus 1% of that balance for each full month you are late, to a maximum of 12 months, which caps it at 17% for any one year (CRA, 2025).
The repeated late-filing penalty doubles it, to 10% plus 2% per full month to a maximum of 20 months, or 50%. It applies where you were already penalized on a return for one of the three previous tax years and CRA had issued a demand to file. For a 2025 return CRA describes that as being penalized “in 2022, 2023, or 2024” and having received a demand (CRA, 2025).
On top of the penalty, CRA “charges compound daily interest starting the day after the due date” (CRA, 2025). The rate resets quarterly, and for July 1 to September 30, 2026 it is 7% (CRA, 2026). It resets again on October 1, so check CRA’s prescribed interest rates for the quarter you are actually in.
| Standard | Repeated | |
|---|---|---|
| Base | 5% of balance owing | 10% of balance owing |
| Per full month late | 1% | 2% |
| Month cap | 12 | 20 |
| Maximum | 17% of balance | 50% of balance |
Worked example: a 2022 return filed in 2026
Your 2022 return was due April 30, 2023 and shows $4,000 owing, and this is your first late year. At 5% plus 1% for twelve full months, the penalty is 17% of $4,000, or $680. Interest runs on the unpaid balance from May 1, 2023, compounded daily at whatever rate applied each quarter. At the current 7%, compounded daily, one year of interest on $4,000 is about $290. An illustration, not a quote.
Now the part nobody tells frightened people. The penalty is a percentage of the balance owing, so if you are owed a refund, 17% of nothing is nothing. Interest works the same way. A refund year filed nine years late costs no penalty and no interest.
What CRA does if you keep not filing
CRA escalates in a predictable order, and it does so slowly.
1. Letters and calls. Once a Non-Filer Program letter arrives you “are legally required to file the return(s),” and an officer may phone with a deadline (CRA, 2026).
2. An arbitrary assessment. This is the step most people have never heard of, and the one that does the financial damage. If you do not file and CRA believes tax is owing, it can assess you anyway under subsection 152(7), building the return from the slips it already holds. It “won’t include voluntary deductions you may have been eligible for,” and it estimates business expenses from an average of your earlier filings (CRA, 2026).
A self-employed year where you grossed $70,000 and spent $28,000 earning it can be assessed close to the gross. RRSP deductions, tuition, childcare, medical, none of it appears, because CRA does not know about any of it.
That assessment is a real, collectible debt. It is also not final. Filing the true return for that year is how the number comes down. Interest keeps running on the assessed amount in the meantime, which is why sitting on one is expensive.
3. Collections. An assessed balance is collectible, and CRA’s guidance is to contact its Collections department to arrange terms if you cannot pay (CRA, 2026).
4. Prosecution. CRA describes this as a final step: the Non-Filer Program “may consider an enforcement action called a prosecution,” and someone convicted “may face a fine, jail sentence or, a combination of the two” (CRA, 2026). It comes after demands have gone unanswered, not after a late filing.
The Voluntary Disclosures Program
The Voluntary Disclosures Program (VDP) is not the same thing as filing late. Filing late is just filing, with penalties and interest applied as calculated. The VDP is a separate application asking CRA to give up the penalties and some of the interest because you came forward first. CRA grants that relief “on a case-by-case basis to taxpayers and registrants who come forward to fix errors or omissions in their tax filings” (CRA, 2026).
CRA rewrote the program effective October 1, 2025. The old general and limited streams are gone, replaced by unprompted and prompted applications, and the relief differs sharply.
| Unprompted | Prompted | |
|---|---|---|
| What it means | No CRA communication about the issue you are disclosing, or only a general education letter | CRA has already contacted you about a specific error or omission, set a deadline to comply, or received third-party information about you |
| Interest relief | 75% of applicable interest | 25% of applicable interest |
| Penalty relief | 100% of applicable penalties | Up to 100% of applicable penalties |
Source: CRA, IC00-1R7, 2026.
That table is the argument for acting before the letter arrives. Going from unprompted to prompted costs you two thirds of the available interest relief, 75% down to 25%, and it turns on a phone call whose timing you do not control.
The five conditions
CRA says you “must meet all five conditions” for a valid application (CRA, 2026):
- You apply before an audit or investigation has been started on the information you are disclosing.
- You include all relevant information and documentation for every tax year involved.
- The information involves an error or omission that attracts interest or a penalty, or both.
- The information is at least one year or one reporting period past its filing due date.
- You include payment of the estimated tax owing, or request a payment arrangement, subject to CRA approval.
Relief under the VDP also means you “will not be referred for criminal prosecution” on the disclosed matter. Nothing is automatic, and CRA says so: “The CRA is not required to grant relief for all applications made to the VDP. Each request will be reviewed and decided on its own merits” (CRA, 2026).
One practical read: if every unfiled year is a refund year, there is nothing to relieve, because there are no penalties and no interest. The VDP matters when you have years with a balance owing, unreported income, or foreign assets.
How to actually do the catch-up
This sequence is the whole job, and the hardest part is the first hour.
1. Get into your CRA account, or authorize someone. Everything you need to rebuild the missing years lives there. You can add a representative in your CRA account, confirm a request your accountant submits through Represent a Client, or sign Form AUT-01 for offline access, which must reach the tax centre within six months of signing (CRA, 2026).
2. Pull the slips CRA already holds. Auto-fill my return delivers T4, T4A, T5, T4RSP, T2202 and other slips into certified software for 2016 and subsequent tax years (CRA, 2026). For most people that covers the entire catch-up.
3. Work out what is missing. CRA never sees self-employment income, rent you collected, tips, most foreign income, or any of your deductions. Its own warning applies: you must make sure the return “is true, accurate and complete,” whatever the slips downloaded (CRA, 2026).
4. Reconstruct the rest. Bank and credit card statements, invoices, rent receipts, tuition records, RRSP confirmations, a pharmacy printout. Banks produce old statements on request. Our document checklist for a personal return works just as well pointed backwards at an old year.
5. File oldest to newest. Tuition carryforwards, capital losses, RRSP room and unused credits all flow from one year into the next, and a return filed out of sequence can be assessed without them.
6. Then deal with the balance. You will not know what you owe, if anything, until the assessments come back. Do not let a guess about that number stop you.

If you owe money you cannot pay
Filing and paying are separate obligations, so file anyway. A filed return with an unpaid balance costs you interest. An unfiled one costs you interest, the late-filing penalty, and eventually an arbitrary assessment built without your deductions.
A payment arrangement lets you schedule a series of payments instead of clearing the balance at once. Set one up in your CRA account under “Schedule a series of payments” as a pre-authorized debit, or through the automated TeleArrangement service at 1-866-256-1147. CRA points you to an income and expense worksheet first, so the monthly figure is one you can sustain (CRA, 2026).
Taxpayer relief is the separate route for the penalties and interest themselves. CRA may cancel or waive them where the cause falls into one of three categories: extraordinary circumstances, actions of the CRA, or inability to pay and financial hardship. Extraordinary circumstances covers serious illness or accident and serious emotional or mental distress, the ground that fits a lot of long catch-ups (CRA, 2026).
The same ten-year clock applies: 10 years from the end of the calendar year in which the tax year ended, on Form RC4288. CRA “may” grant it. Nobody, us included, can tell you that it will.
Getting your benefits turned back on
Most of them restart without a separate application.
Once CRA assesses the filed returns, it determines your eligibility and issues what you were owed as retroactive payments on the next scheduled payment date (CRA, 2026). The Canada Groceries and Essentials Benefit works the same way (CRA, 2026), and the Canada Workers Benefit comes straight out of line 45300.
Two things need more than a filed return. CCB for a period that started more than 11 months ago is applied for on Form RC66 with mailed documents: proof of citizenship or immigration status, at least three documents proving residency in that period, proof of birth for each child, and at least three showing you were primarily responsible for their care (CRA, 2026). Start gathering those while the returns are being prepared. GIS is renewed by Service Canada off your filed return and reassessed each July (Service Canada, 2026).
If your CCB restarts lower than you remember, that is usually an income change rather than an error. We covered the common reasons in why your CCB payment dropped.
Common Questions
Will CRA come after me if I file returns from six years ago?
Filing is exactly what CRA asks non-filers to do (CRA, 2026). It does not start an audit, and it stops the escalation described above. If you have unreported income in those years, get advice on the VDP first, because applying after CRA contacts you drops the interest relief from 75% to 25%.
I already got an assessment for a year I never filed. Is it too late?
No. An arbitrary assessment under subsection 152(7) is CRA’s estimate, and it deliberately leaves out deductions CRA does not know about (CRA, 2026). Filing the real return is the mechanism for correcting it.
Can I file just the years where I am getting money back?
You can file in any order, but leaving balance-owing years unfiled keeps penalties and interest running and leaves you exposed to an arbitrary assessment. CRA can also apply a refund from one year against a balance from another, so filing everything gives you the real net number.
What if I genuinely have no records for 2017?
Reconstruct what you can. Slips from 2016 onward come straight from CRA (CRA, 2026), and banks produce historical statements on request. A return built on a reasonable, documented reconstruction beats no return.
Where to start this week
Pick the oldest year. If your unfiled returns reach back to 2016, that year stops being refundable on December 31, 2026, so it goes first. Register for your CRA account or sign an authorization so the slips can be pulled. Then work forward, one year at a time, and let the assessments tell you what the balance is instead of guessing in the dark.
Most people find the number is smaller than the version they built up over years of not opening the mail, and a good share find CRA owes them. If you would rather hand over the stack, start with a conversation about filing outstanding tax returns. It is also why we tell clients to prioritize tax filing even in a year with no income.
