Taxpayer Relief (Form RC4288): How to Ask the CRA to Cancel Penalties and Interest
When the CRA will cancel penalties and interest under taxpayer relief, the 10-year limit, what evidence works, and why 'my accountant dropped me' rarely does.
The CRA can cancel or waive penalties and interest under its taxpayer relief provisions when they result from extraordinary circumstances (serious illness, disaster, death in the family), CRA error or delay, or a real inability to pay. You apply on form RC4288 within 10 calendar years of the end of the year the penalty or interest relates to. Relief is discretionary, and evidence matters more than the story.
Taxpayer relief doesn't reduce the tax itself. It only deals with penalties and interest. But on a business that's a few years behind on its T2, GST/HST or payroll, penalties and interest can add up to a large share of the balance, so a well-prepared request is often worth the effort.
What taxpayer relief can and can't cancel
| Can be cancelled or waived | Not covered |
|---|---|
| Late-filing penalties (T2, T1, GST/HST, information returns like T4s) | The tax itself |
| Failure-to-remit penalties on payroll source deductions | Amounts for years outside the 10-year limit |
| Arrears interest on balances owing | Penalties you simply disagree with on technical grounds (that's an objection) |
| Instalment interest and penalties | Relief that relies only on "I didn't know" |
If you think the assessment itself is wrong, taxpayer relief is the wrong tool. A notice of objection challenges the amount assessed. Taxpayer relief accepts the amount is right and asks the CRA to forgive the penalties and interest because of what happened to you.
The three grounds (plus "other circumstances")
The CRA's guidance, Information Circular IC07-1R1, sets out when relief may be granted (canada.ca, IC07-1R1).
| Ground | What usually qualifies | What the CRA wants to see |
|---|---|---|
| Extraordinary circumstances | Serious illness or accident, natural disaster or flood, fire, death of an immediate family member, civil disturbance or postal disruption | Dated proof the event happened and that it stopped you filing or paying on time |
| Actions of the CRA | Processing delays, wrong written information from the CRA, errors in CRA material, delays in providing information | The CRA letter, call notes, dates and reference numbers |
| Inability to pay or financial hardship | Usually interest relief, sometimes penalties, where paying would cause real hardship or threaten the business continuing | Full financial disclosure: income, expenses, assets, debts and a payment plan |
The CRA can also consider other situations that don't fit neatly into these boxes, but the same test applies: something outside your control caused the non-compliance, and you acted to fix it once you could.
Will "my accountant let me down" work?
On its own, rarely. The CRA generally treats taxpayers as responsible for their own filings, including when they hire a representative. "My accountant didn't file" or "my bookkeeper quit" is usually seen as something you could have caught.
It can help when it's part of a bigger picture. For example, the accountant's failure happened while the owner was seriously ill, or the CRA itself delayed processing an authorization. This comes up a lot. See accountant not responding and my accountant passed away.
How to build a strong request
- File every outstanding return first. Relief on periods that are still unfiled is rarely granted. The CRA wants to see that you're back in compliance.
- Pick the right periods. List each tax year or reporting period, the program (income tax, GST/HST, payroll) and the penalty or interest you want cancelled. Don't ask for everything if the event only covered part of it.
- Write a clear timeline. What happened, when it started, when it ended, and how it stopped you filing or paying on time.
- Attach proof. Medical letters with dates, death certificates, insurance claims, photos of flood or fire damage, CRA letters and call logs. A short, documented request beats a long story with no evidence.
- Show what you did once you could. Returns filed, balances paid or a payment arrangement in place. Relief is much more likely for the period you couldn't act than for the months after.
- Submit it properly. Use form RC4288 (canada.ca, RC4288), or the online request in My Account, My Business Account or Represent a Client. Incomplete requests sit longer while the CRA asks for more, so send everything up front.
The 10-year limit, in plain terms
You have 10 calendar years from the end of the tax year or fiscal period to ask. A request made in 2026 can generally cover tax years ending in 2016 or later. For interest on a balance that has been owing for a long time, relief is limited to the interest that built up in the 10 calendar years before the year you apply. Older amounts can't be touched, which is another reason not to wait.
How long does it take?
Expect a wait. The CRA has posted average processing times of about 16 months for taxpayer relief requests, depending on how complex the request is, how many years and programs are involved, and how complete your documents are (canada.ca, cancel or waive penalties and interest). You can track online requests through the CRA Progress Tracker.
Interest keeps running on any unpaid balance while you wait. If you can pay the tax, paying it stops most of the interest from growing, and you can still get penalties and interest refunded if relief is granted.
Example (hypothetical): a clinic owner's hospital stay
An Ontario clinic owner was hospitalized for several months in 2024 and missed four HST quarters and a T2. After recovery, all returns were filed within a few months and an RC4288 was submitted with hospital admission and discharge records, a short timeline, and proof the returns were now filed.
- Penalties for the periods covered by the hospital stay: a reasonable request with strong evidence.
- Interest during the illness: also worth asking for.
- Interest after recovery: less likely to be relieved, since the owner was able to act from that point.
Example (hypothetical): when relief isn't the right route
A Calgary contractor's corporation hadn't filed for three years. No CRA letters had arrived and nothing unusual had happened. The owner just fell behind while the business grew. Taxpayer relief is a weak fit here because there's no circumstance beyond the owner's control. The better route was the Voluntary Disclosures Program, applied for before any CRA contact.
VDP or taxpayer relief?
| Voluntary Disclosures Program | Taxpayer relief | |
|---|---|---|
| When | Before the CRA contacts you about the issue | After penalties or interest are charged |
| Why you qualify | You come forward on your own | Circumstances beyond your control, CRA error, or hardship |
| Form | RC199 | RC4288 |
| Typical use | Never filed, unreported income, unremitted GST/HST | Illness, disaster, CRA delay, inability to pay |
If the CRA hasn't contacted you and you haven't filed, look at VDP first. Taxpayer relief is for amounts already assessed. More on how penalties are calculated in CRA late filing penalties explained.
If your request is denied
You can ask for a second administrative review, done by a different CRA officer. Send new information or explain what the first review missed. If that's denied too, you can apply to the Federal Court for judicial review, generally within 30 days of the decision. The court looks at whether the CRA's decision was reasonable. It doesn't redo the request.

FAQ
How far back can I ask for taxpayer relief? Ten calendar years from the end of the tax year or fiscal period the penalty or interest relates to. For long-running balances, only the interest from the last 10 calendar years can be relieved.
Can I apply for relief on GST/HST penalties? Yes. The RC4288 covers income tax, GST/HST and payroll penalties and interest.
What if my relief request is denied? You can ask for a second administrative review, and after that apply to the Federal Court for judicial review, generally within 30 days of the decision.
Should I pay while the request is reviewed? Generally yes, or set up a payment arrangement. Interest keeps running on unpaid amounts during the review, and amounts paid can be credited back if relief is granted.
Is financial hardship enough for full penalty relief? Hardship more often leads to interest relief, and it needs detailed financial disclosure.
Can my bookkeeper or accountant submit the request for me? Yes, if they're authorized as your representative with the CRA. They can submit it online through Represent a Client.
