Taxpayer Relief — Ontario
Sourced from Canadian federal statutes and official sources. Provincial information reflects each province's own legislation and court rulings. Written in plain language for general understanding — this is educational content, not legal advice. Our editorial standards
What is this right?
Subsection 220(3.1) gives the CRA the power to cancel or waive penalties and interest. The program goes by "taxpayer relief" — older filings still call it the "fairness provisions."
Relief covers penalties and interest only — not the underlying tax. The CRA recognises three grounds:
- Extraordinary circumstances — natural disaster, serious illness, accident, emotional distress.
- CRA errors or delays — bad information from CRA staff, processing failures, errors in CRA publications.
- Financial hardship — inability to pay caused by circumstances outside your control.
The 10-year lookback is the rule that quietly costs people money: relief is only available for tax years within the past 10 calendar years, and one year falls off every January.
Apply by completing Form RC4288 or by submitting a detailed letter with supporting documents.
When does it apply?
Applies to any taxpayer who has been hit with penalties or interest by the CRA.
- You need to make out at least one of the three grounds: extraordinary circumstances, CRA error/delay, or financial hardship.
- The 10-year window is hard — older years simply aren't available for relief.
What to Do If the CRA Charged You Penalties or Interest You Believe Are Unfair
- Complete Form RC4288 — online or by calling CRA.
- Submit through My Account or by mail.
- Build a detailed explanation with documents to back it: medical records, insurance claims, CRA correspondence, financials. Vague stories lose.
- Denied at first? Ask for a second-level review. A different officer takes a fresh look.
- If second-level is also denied, the next stop is Federal Court judicial review.
What should you NOT do?
- Don't wait. Every January, another year drops off the lookback window.
- Don't file vague applications. Specific dates, amounts, documents.
- Don't assume "I forgot" qualifies. You need circumstances genuinely outside your control.
- Don't confuse relief with a payment plan. Relief erases penalties and interest; a plan just stretches the timeline.
- Don't give up at the first denial. Second-level reviews routinely flip — a fresh officer means a fresh chance.
How Ontario differs from federal law
Taxpayer relief provisions let you ask the CRA to waive penalties and interest in certain circumstances. Ontario income tax relief is handled through the same CRA process as federal tax.
- Under the CRA Taxpayer Relief provisions (section 220(3.1) of the federal Income Tax Act), you can request cancellation or waiver of penalties and interest for up to 10 calendar years if there were extraordinary circumstances: serious illness, natural disaster, financial hardship, or CRA errors/delays.
- You can also request relief if you missed a filing deadline due to circumstances beyond your control. The CRA can accept a late-filed election or allow an amendment.
- Ontario has its own Ontario Trillium Benefit (OTB), which combines the Ontario Energy and Property Tax Credit, the Northern Ontario Energy Credit, and the Ontario Sales Tax Credit. If you missed claiming the OTB, you can request a reassessment for prior years.
- The Taxpayers' Ombudsman (an independent federal office) can investigate service complaints about the CRA, including unresolved taxpayer relief requests.
Additional Steps in Ontario
