A CRA penalty notice lands, you file Form RC4288, and then you wait. As at July 2026 that wait averages 16 months, while the interest on your balance keeps compounding daily at 7%. Filing the request is the easy part. Sequencing it properly is what saves you money.
Key takeaways
- Form RC4288, "Taxpayer Relief Request – Cancel or Waive Penalties and Interest," is the Canada Revenue Agency form used to ask for relief from penalties and interest under subsection 220(3.1) of the Income Tax Act. It cannot touch the underlying tax.
- The CRA's average processing time for a taxpayer relief request was 16 months as at 16 July 2026, against a published service standard of 180 calendar days that it aims to meet 85% of the time.
- Interest does not pause while your request sits in the queue. The prescribed rate on overdue tax is 7% for the quarter ending 30 September 2026, compounded daily.
- Information Circular IC07-1R1 paragraph 23 lists three circumstance categories, not four: extraordinary circumstances, actions of the CRA, and inability to pay or financial hardship. The form's eighth reason, "other circumstances," rests on paragraph 24 instead.
- The 10-year limit is not one window. For a penalty it runs from the end of the tax year. For interest it runs against the years the interest accrued, so a tax debt from 2011 can still produce interest relief on a request filed in 2026.
What CRA Form RC4288 is, and what it cannot do
The Canada Revenue Agency uses one form for discretionary relief from penalties and interest. The current version is RC4288 E (25), a six-page form, and the canada.ca form page was last updated 19 May 2025.
Watch the name. The form itself is now titled "Taxpayer Relief Request – Cancel or Waive Penalties and Interest." IC07-1R1 still calls it the "Request for Taxpayer Relief – Cancel or Waive Penalties or Interest," because the circular has not been revised since 18 August 2017. Same form, older label. If a search result shows you the old title, you are still in the right place.
The power behind the form is subsection 220(3.1) of the Income Tax Act. Two words in that provision decide most files. The Minister "may" waive or cancel, so relief is discretionary and no taxpayer is entitled to it. And the power reaches a penalty or interest only. Your tax debt itself is out of scope. Filing the CRA taxpayer relief form does not eliminate penalties automatically, and it is not a way to negotiate what you owe.
If the real problem is a mistake in the return rather than a penalty, that is a different fix. Our guide to correcting a CRA filing mistake covers that route.
The sequencing mistake that costs the most money
Most advice on this topic stops at "file the form." That advice quietly assumes the CRA answers quickly. It does not.
The CRA's own Cancel or waive penalties and interest page, last modified 16 July 2026, states that it is receiving a higher-than-normal number of requests and that the average processing time is currently sixteen months. The published service standard is 180 calendar days. The 2024-25 Departmental Results Report explains the gap: the CRA received 109,374 taxpayer relief requests that year, a 16% increase over the prior year, with financial hardship the leading reason given.
Meanwhile, IC07-1R1 section 22.1 is blunt. The CRA continues to charge compound daily interest at the prescribed rate on any amount owing while a request is pending. The prescribed rate on overdue tax has held at 7% since 1 July 2025 and applies through 30 September 2026.
So the right order of operations looks like this:
- Stop enforcement first. Call the CRA and put a payment arrangement in place so collections activity does not escalate while you wait.
- File the RC4288 request in parallel, not afterwards. The 10-year clock is running and the queue is long.
- Keep paying down the principal while the request sits. Every dollar of tax you retire is a dollar that stops generating interest.
- If relief is granted later, the CRA pays refund interest on penalty and interest amounts you already paid and it then cancelled. You are made whole.
That last point is why paying first and claiming after is usually the cheaper strategy. Waiting sixteen months with a live balance is not a neutral choice.
Worked example: what 16 months of interest costs an Oshawa business
An Oshawa contractor files his T2 late and lands a $4,200 late-filing penalty plus arrears interest on a $38,000 corporate balance. He has a strong case: a hospital admission in February that is documented, and a clean 12-year compliance history.
If he files the RC4288 request and simply waits, the $38,000 keeps accruing arrears interest at 7% compounded daily for the sixteen months the review takes. That is roughly $3,700 of new interest generated during the wait, on top of everything already assessed.
If instead he sets up a payment arrangement and clears the $38,000 in even instalments over ten months, the average balance carrying interest is about half as large for two-thirds as long. New interest lands near $1,100. The relief he is asking for does not shrink by a dollar, and if the delegated official cancels the $4,200 penalty and the arrears interest tied to it, the CRA refunds those amounts with refund interest on top.
The request is the same either way. The cash outcome is not.
When the CRA will cancel or waive a penalty
IC07-1R1 paragraph 23 sets out three circumstance categories. A great deal of secondary commentary says four. It is wrong, and the distinction matters when you are drafting the narrative in Section 6 of the form.
Extraordinary circumstances
Situations beyond your control. The circular's examples include natural or human-made disasters such as flood or fire, civil disturbances or service disruptions such as a postal strike, serious illness or accident, and serious emotional or mental distress such as a death in the immediate family.
Actions of the CRA
Penalties and interest caused mainly by the agency itself: processing delays that left you uninformed that an amount was owing, errors in published material, incorrect information given to you, processing errors, delays in providing information, and undue delays in resolving an objection or completing an audit. CRA delays of this kind are a stronger ground than most people assume, and they are frequently under-argued.
Inability to pay or financial hardship
Framed as interest relief to enable you to pay the debt. It covers collection being suspended for inability to pay, extended payment arrangements, situations where paying the accumulated interest would cause a prolonged inability to provide basic necessities, and cases where interest charges would absorb so much of each payment that no reasonable arrangement is possible.
The RC4288 turns these into eight selectable reasons:
| Reason on Form RC4288 | IC07-1R1 category |
|---|---|
| Financial hardship, individual | Inability to pay or financial hardship |
| Financial hardship, business | Inability to pay or financial hardship |
| Natural or human-made disaster | Extraordinary circumstances |
| Death, accident, serious illness, emotional or mental distress | Extraordinary circumstances |
| Civil disturbance or disruption in services | Extraordinary circumstances |
| CRA error | Actions of the CRA |
| CRA delay | Actions of the CRA |
| Other circumstances (specify) | Paragraph 24 residual, not a listed ground |
That last row is the one people get wrong. "Other circumstances" is not a fourth ground in the circular. It works because paragraph 24 says the guidelines are not binding and the Minister's delegate may grant relief where the facts fall outside paragraph 23. The Federal Court said the same thing in Chekosky v Canada (Revenue Agency), 2019 FC 841. If your situation does not fit a listed box, you are not automatically out.
The four factors that decide your request
Once a qualifying circumstance is established, IC07-1R1 section 33 directs the delegated official to weigh four separate factors. These are not the categories above. Conflating the two is the most common drafting error in relief applications.
- Whether you have a history of compliance with your tax obligations.
- Whether you knowingly allowed a balance to exist on which arrears interest accrued.
- Whether you exercised a reasonable amount of care and were not negligent or careless under the self-assessment system.
- Whether you acted quickly to remedy the delay or omission.
Write Section 6 of the form so it answers all four directly, with dates. A clean filing record for a Whitby business that missed one deadline during a documented hospital stay reads very differently from three years of silence followed by a request. In Cassidy v Canada (Attorney General), 2024 FC 174, the Federal Court quashed a relief decision precisely because the officer's reasons were silent on these considerations, and sent the file back to a different taxpayer relief officer.
Financial hardship: the trap that catches penalty claims
Financial hardship is the reason most people select, and it is the reason most likely to be misunderstood.
IC07-1R1 section 28 says that cancelling a penalty for inability to pay "would not generally be considered, unless an extraordinary circumstance prevents compliance." Hardship is fundamentally a ground for interest relief. There is one narrow exception, for a business in extreme financial difficulty where enforcing the penalties would jeopardize the continuity of its operations, the jobs of its employees, and the welfare of the community. That test is repeated word for word in the form's own definition of business financial hardship.
Three practical consequences:
- The financial review is invasive. The CRA examines income and expenses, assets and liabilities, your ability to borrow or sell assets, and the efforts you have made to pay. For an individual it also considers the income, expenses, assets and liabilities of household members such as a spouse or common-law partner.
- Individuals should attach Form RC376, Taxpayer Relief Request – Statement of Income and Expenses and Assets and Liabilities for Individuals. Businesses instead provide a written statement of income, expenses, assets and liabilities supported by a statement of earnings and a balance sheet. If your books are not in shape for that, start with clean bookkeeping and compiled financial statements.
- A hardship grant is not permanent. Under section 28.2 the CRA cancels interest only up to the date of the decision. If your situation has not improved, you must file a further request for interest accruing after that date. Put a reminder in your calendar the day the decision letter arrives.
The 10-year window for penalty relief and interest relief
This is the single most misstated point in this area, including in professional commentary.
You will read that relief is unavailable on a tax debt more than ten years old. For interest, that is exactly the position the Federal Court of Appeal rejected in Bozzer v Canada, 2011 FCA 186. The Court held that the Minister may cancel interest that accrued during the ten taxation years preceding the application, and that the year the tax debt arose is irrelevant. Mr. Bozzer's debts dated from 1989 and 1990; his December 2005 application still reached the interest that accrued from 1 January 1995 to 31 December 2004. The CRA adopted that reading on its own revised 10-year limitation page.
Penalties work on a different clock entirely.
| Penalty relief | Interest relief | |
|---|---|---|
| What the 10 calendar years attach to | The tax year or fiscal period at issue | The calendar years in which the interest accrued |
| Test | The year must have ended within 10 years before the calendar year of your request | Interest accrued in the 10 calendar years before the year of your request |
| Effect of an old debt | Bars relief once the year falls out | Does not bar relief, however old the debt |
| Rolls forward | Every 1 January | Every 1 January |
Two consequences follow. First, a single request can be in time for interest and out of time for the penalty on the same tax year, because section 15.3 keeps the penalty portion tied to the tax-year clock. Second, once the window closes the Minister has no authority at all. That is a jurisdictional bar, not a discretionary refusal, and no amount of sympathy reopens it.
Where an audit, objection or appeal may not finish before your ten years expire, file a protective request now under section 16 and supply the detail once the dispute concludes.
How to request relief: completing Form RC4288 section by section
The form runs to seven sections and is marked Protected B when completed. Do not include personal information beyond what each field asks for.
| Section | What it asks for |
|---|---|
| 1. Taxpayer identification | Name, mailing address, city, province or territory, postal code, country if outside Canada, and two telephone numbers |
| 2. Authorized representative identification | Whether you are filing for someone else, and confirmation that the representative holds at least level 2 authorization on every account involved. Without it the form cannot be submitted on another person's behalf |
| 3. Details of request | Whether you are seeking penalty relief, interest relief or both; the penalty type; the interest type; the amounts listed separately; the tax years or periods; and your account numbers, SIN for personal plus the business numbers by program |
| 4. Reasons and supporting documents | One of the eight reasons above, each with its own document checklist |
| 5. Previous decision | Only for a second review. Enter the case number from your decision letter, which starts with GB, and explain what you disagree with and what is new. Completing this section means you skip Section 6 |
| 6. Supporting details | The narrative. Why the return or payment was late, plus the key dates that connect the circumstance to the failure |
| 7. Certification | Name, signature and date in Year/Month/Day format |
Section 6 is where requests are won and lost. A serious illness that did not overlap the filing deadline will not carry the file. Representative authorization is granted through the Authorized Representatives section of CRA My Account, My Business Account or My Trust Account, in writing, or on Form AUT-01.
Before you complete and submit, run the CRA's Self-Evaluation and Learning Tool, issued 20 May 2025 and referenced on the face of the form. It does not save or submit anything to the CRA, so it is a safe rehearsal.
Where to submit your request
The CRA prefers online. The service is called "Request relief of penalties and interest" and it sits inside CRA My Account, My Business Account or Represent a Client. You can also upload a completed fillable form and its attachments through the Submit documents service after you sign in.
If you are mailing paper, there is no single national tax centre. The routing is geographic:
| Where you live | Where the form goes |
|---|---|
| Ontario, Quebec, New Brunswick, Nova Scotia, Prince Edward Island, Newfoundland and Labrador | Prince Edward Island Tax Centre, 275 Pope Road, Summerside PE C1N 6A2 |
| Alberta, British Columbia, Saskatchewan, Manitoba, Northwest Territories, Nunavut, Yukon | Eastern Prairie Tax Services Office, Taxpayer Relief, 800-360 Main Street, PO Box 1022 Station Main, Winnipeg MB R3C 2W2 |
| Non-resident or international | Either office |
Clients in Oshawa, Whitby, Ajax and Bowmanville all file to Summerside. A letter is technically acceptable in place of the form under section 29 of the circular, but the form is safer because it forces you through the reason-by-reason checklist.
Supporting documents that carry weight
Section 32 of the circular tells you to put every circumstance you are relying on into the first request. Do not hold anything back for a later round. Strong documentation is what separates a granted file from a refused one.
What the form asks for, by reason:
- Individual hardship: Form RC376, plus bank and credit card statements for the last three months.
- Business hardship: a written statement of income, expenses, assets and liabilities, with a statement of earnings and a balance sheet.
- Medical: a doctor's certificate or letter stating the length of treatment, any hospital dates, and how the condition affected you.
- CRA error from written material: the material itself, and the date you relied on it.
- CRA error from a phone call: the date, time, name and agent identification number of the CRA official, plus what was said.
- Civil disturbance: usually nothing, if the event is public knowledge in Canada.
Every reason block also has an "I will not be providing supporting documents" checkbox. Ticking it is a poor idea. The form warns that missing documents cause processing delays, and the current queue is long enough already.
What happens after you file
The CRA sends an acknowledgement letter on receipt and may contact you for clarification or additional information. A decision letter follows.
Behind the scenes, two officials are involved. One reviews the file and writes a decision report with a recommendation. A separate delegated official, acting under subsection 220(2.01), makes the final decision and signs the notification. That structure matters if you ever end up in Federal Court, because it is the delegate's reasons that get scrutinized, not the reviewer's.
If relief is granted after you have already paid, the CRA refunds the cancelled penalty and interest with refund interest.
If the CRA refuses
You cannot object. Subsection 165(1.2) bars a notice of objection against a taxpayer relief decision, and the circular says plainly at section 103 that there is no right of objection or appeal. The Tax Court of Canada has no jurisdiction here. Two routes remain.
Second administrative review
Ask that another delegated official reconsider. Officials not involved in the first decision conduct it, a fresh decision report is prepared, and a different delegate signs the outcome. For a subsection 220(3.1) decision you make this request on Form RC4288 itself, using Section 5 and the GB case number. Add whatever new information the first decision did not consider. The CRA publishes no deadline for asking, and you should be wary of any source that quotes one.
Judicial review in the Federal Court
File an application under section 18.1 of the Federal Courts Act within 30 days of receiving notification of the decision, on Federal Court Form 301. A judge may extend that time, before or after the 30 days have run.
Understand what winning buys you. The Court cannot substitute its own decision or order the CRA to cancel anything. It can only send the matter back to be reconsidered by another delegated official. That was the outcome in Cassidy and again in Minion v Canada (Attorney General), 2025 FC 1461, where the Court set the decision aside but refused to order reimbursement. The strongest arguments attack the quality of the delegate's reasoning rather than re-arguing the facts, because the Court will not reweigh evidence. In Stemijon Investments Ltd v Canada (Attorney General), 2011 FCA 299, a decision that looked only at the circular instead of the statute was held to be the product of a fettered discretion and unreasonable for that reason alone.
One trap to watch. If your relief request was tied to an objection or appeal, section 110.1 records that the CRA may ask you to sign a waiver of your right to a second administrative review and judicial review once the dispute concludes. Do not sign that reflexively. It closes both doors.
Carrying a CRA balance? Get the RC4288 filed right
Penalty and interest files turn on two things: whether the narrative in Section 6 connects your circumstance to the missed deadline, and whether you handled the balance sensibly while the CRA took its sixteen months. We handle both. If you have a CRA balance you are carrying, or a decision letter you want a second read on, we work with business owners and individuals across Durham Region, from Whitby to Clarington.
