Form RC4288, Request for Taxpayer Relief, is the CRA form used to ask the Minister to cancel or waive penalties and interest under section 220(3.1) of the Income Tax Act or section 281.1 of the Excise Tax Act for GST/HST. It does not cancel the underlying tax debt, and relief generally reaches back only 10 calendar years.
That distinction is the single most important thing to understand before filing. RC4288 is a request for CRA forgiveness of interest and penalties, not a debt settlement tool. The tax your corporation actually owed remains owing. What the Minister has discretion to erase is the interest that has compounded on top of it and the penalties layered onto late filings and late remittances.
The taxpayer relief CRA offers corporations is discretionary, not automatic, and it applies only to interest and penalties, never to the tax itself. For a business, that discretion is worth pursuing. A corporation that fell three quarters behind on GST/HST remittances, or that missed several payroll source deduction deadlines during a cash crunch, can find that penalties and compounding interest have grown into a five or six figure problem of their own. Taxpayer relief will not fix a viability problem, but it can stop a solvable arrears file from turning into an unsolvable one. At Hadri Law, our corporate tax practice regularly works with business owners at exactly this stage, often while a director liability assessment is already in motion.
The Legal Basis: Two Statutes, One Form
Taxpayer relief is not a negotiation. It is a statutory discretion granted to the Minister of National Revenue, and it lives in two places.
For income tax, including corporate income tax and payroll source deduction penalties and interest, the authority is subsection 220(3.1) of the Income Tax Act (ITA s. 220). It allows the Minister to waive or cancel all or any portion of any penalty or interest otherwise payable.
For GST/HST, the parallel authority sits in section 281.1 of the Excise Tax Act (ETA s. 281.1). Subsection 281.1(1) covers interest, and subsection 281.1(2) covers certain penalties. The structure is deliberately similar, but these are separate grants of discretion applying to separate accounts.
One RC4288 serves both. The form asks you to identify which program account the request relates to, and a business with both an income tax arrears problem and a GST/HST arrears problem needs to be explicit about each. Vague requests that gesture at "our CRA debt" without identifying the accounts, tax years, and reporting periods tend to come back needing clarification, which costs months.
The Three Grounds the CRA Will Actually Consider
CRA's published guidance on CRA tax relief is Information Circular IC07-1R1, Taxpayer Relief Provisions. It sets out the circumstances in which the Agency will normally consider cancelling or waiving penalties and interest.
Extraordinary circumstances. Events largely beyond the taxpayer's control that prevented compliance: natural or human made disasters such as flood or fire, serious illness or accident, serious emotional or mental distress such as the death of an immediate family member, civil disturbances, and disruptions in service such as a postal strike.
Actions of the CRA. Situations where the Agency's own conduct caused or contributed to the problem. This includes processing delays, errors in published information that led a taxpayer to file or pay incorrectly, incorrect information provided by a CRA agent, and undue delays in resolving an objection or completing an audit while interest continued to accrue.
Inability to pay or financial hardship. Cases where paying the accumulated interest would jeopardize an individual's ability to provide basic necessities, or, for a corporation, where continued accrual of interest would jeopardize the continuity of business operations and the jobs of employees. CRA generally expects to see that the taxpayer has made genuine efforts to pay, and it will review the overall financial picture before accepting this ground.
IC07-1R1 also preserves a residual category for other circumstances that may warrant relief. It is applied sparingly, and a request built on it alone is a weak request.
Compliance history matters across all three grounds. A corporation with a clean filing record that fell behind once during a documented crisis is a materially stronger candidate for CRA penalty relief than a repeat late filer whose arrears predate whatever event it now points to. The relief officer will see the full account history regardless of what the submission says, so the submission should address that history directly rather than leave it to be discovered.
The 10 Calendar Year Limitation Period
Relief is time limited. The Minister can only grant relief for a tax year or reporting period that ended within the 10 calendar years before the calendar year in which the request is made.
In practice, a request filed at any point in 2026 can reach tax years and reporting periods ending in 2016 or later. Anything older is beyond the Minister's authority, no matter how compelling the circumstances. This ceiling comes from ITA s. 220(3.1) and ETA s. 281.1 themselves, not from administrative preference, so there is nothing to argue about once a period falls outside the window.
Two practical consequences follow for corporations. First, the clock runs separately for income tax years and for GST/HST reporting periods, so a business carrying multi-year arrears across both accounts has to check each period against the window rather than assume one answer covers everything. Second, the window rolls forward each January, which means the oldest eligible period drops off every year. Waiting to file does not just risk losing periods. It also allows interest to keep compounding on amounts that could have been addressed sooner.
The Corporate Angle: Director Liability, GST/HST, and Payroll
This is where taxpayer relief stops being an accounting question and becomes a personal exposure question.
GST/HST collected from customers, and income tax, CPP, and EI withheld from employees, are deemed trust funds. The corporation holds that money for the Crown. CRA treats a failure to remit trust funds far more seriously than a late corporate income tax payment, and the penalty and interest structure reflects that.
When the corporation cannot pay, CRA can look past it. Directors can be assessed personally for unremitted GST/HST under section 323 of the Excise Tax Act (ETA s. 323) and for unremitted payroll source deductions under section 227.1 of the Income Tax Act (ITA s. 227.1). Both provisions require CRA to have pursued the corporation first, through registration and return of an unsatisfied execution, through liquidation or dissolution proceedings, or through a proved claim in bankruptcy. Both carry a two year limitation period running from the date the person last ceased to be a director of the corporation. Resigning does not erase exposure for remittance failures that occurred while the person was in office.
Three points follow for a business owner in this position.
A corporate relief request and a director's personal relief request are separate. If the corporation files an RC4288 on its GST/HST account, that request does not automatically extend to a director who has been assessed personally under s. 323. Where both exposures exist, both may need their own submission, each identifying its own account and periods.
Taxpayer relief and the due diligence defence are different remedies aimed at different things. Subsections 227.1(3) ITA and 323(3) ETA provide a defence where the director exercised the degree of care, diligence, and skill to prevent the failure that a reasonably prudent person would have exercised in comparable circumstances. That defence challenges whether the director should be liable at all, and it is raised through a Notice of Objection and, if necessary, an appeal to the Tax Court of Canada. RC4288 does not challenge liability. It asks the Minister to exercise discretion over penalties and interest on a liability that is not in dispute. Conflating the two can mean missing an objection deadline while a relief request sits in a queue.
Financial hardship is often the strongest ground available to a corporation under liquidity pressure, but it is evidence intensive. Expect to provide financial statements, cash flow projections, aged receivables and payables, banking information, and a clear explanation of how continued interest accrual threatens operations and employment. Assertions of hardship without supporting documents rarely succeed.
How to Complete and File Form RC4288
The form is available on canada.ca as Form RC4288, Request for Taxpayer Relief. CRA's plain language overview of what relief covers is in Pamphlet 16-3.
A complete submission should identify the taxpayer and the specific program accounts, list every tax year or GST/HST reporting period for which relief is sought, state the amounts of penalties and interest at issue, name the ground or grounds relied on, and set out a clear chronological narrative of what happened and why it prevented compliance. Supporting documentation belongs with the request rather than being promised for later: medical records, death certificates, insurance or disaster claims, CRA correspondence evidencing delay or error, and financial records where hardship is claimed.
Filing options are paper submission to the designated CRA intake centre for the taxpayer's region, or electronic submission through My Account, My Business Account, or Represent a Client by selecting the option to request relief of penalties and interest.
Two things are worth internalizing. The reviewer is assessing a paper record and will never meet the business owner, so organization and documentary support do real work. And processing takes time. CRA does not guarantee a turnaround date, several months is common, and complex files with long account histories take longer.
After You File: First Review, Second Review, Federal Court
A first level review is conducted by a CRA officer, generally in a taxpayer relief section rather than collections. The outcome is a decision letter granting relief in full, granting it in part, or denying it with reasons. Read the reasons carefully, because they define the ground to be fought on next.
If the decision is unfavourable, the taxpayer can request a second administrative review. It is normally assigned to a different officer, not involved the first time, who is generally more senior. A second review that simply restates the original submission rarely changes the result. The value of this stage lies in addressing the specific reasons given for the denial and adding facts or documents that were not before the first reviewer.
If the second review is also unfavourable, the recourse is an application for judicial review to the Federal Court. It is not an appeal to the Tax Court of Canada, which hears disputes about the correctness of assessments rather than the exercise of ministerial discretion. The Federal Court does not decide whether relief should have been granted. It asks whether the Minister's decision was reasonable in the sense described in Canada (Minister of Citizenship and Immigration) v. Vavilov, including whether the reasons were intelligible and responsive to the evidence before the decision maker. Where the Court finds the reasoning inadequate, the usual remedy is to send the matter back to CRA for redetermination rather than to order relief. Strict deadlines apply to commencing judicial review: under section 18.1(2) of the Federal Courts Act, an application must generally be filed within 30 days after the decision was first communicated to the affected party, though the Federal Court can allow further time. This step needs prompt legal advice.
Keep one more distinction clear throughout. A Notice of Objection under section 165 of the Income Tax Act challenges whether an assessment is correct. Taxpayer relief accepts the assessment and asks for discretion on penalties and interest. They run on different timelines and different tracks, and a business that needs both should be running both.
RC4288 Is Not the Voluntary Disclosures Program
These two programs are routinely confused, and the consequences of confusing them are practical.
RC4288 addresses penalties and interest on amounts CRA already knows about, typically because returns were filed late, remittances were missed, or an assessment or reassessment has already issued. There is no requirement that the taxpayer come forward first. A relief request can be filed after CRA has made contact, after an audit, and after collections activity has begun.
The Voluntary Disclosures Program, applied for on Form RC199, is for taxpayers proactively correcting non-compliance CRA has not yet identified: unfiled returns, unreported income, unreported GST/HST. Under changes effective October 1, 2025, the program is no longer limited to fully unprompted disclosures. An unprompted application, made before CRA has contacted the taxpayer about the issue, still receives the most generous relief: up to 75% interest relief and up to 100% penalty relief. A prompted application, made after CRA communications about a potential compliance issue, can still qualify but receives less: up to 25% interest relief and up to 100% penalty relief. Taxpayers already under audit or investigation, or with egregious non-compliance, generally remain ineligible either way. A VDP application still requires payment of the tax owing plus interest.
A business with a long non-compliance history may genuinely need both, in sequence: correct the unfiled or under-reported periods through VDP, then separately seek RC4288 relief for penalties and interest tied to a specific extraordinary event, financial hardship, or CRA delay that VDP does not address. What does not work is filing an RC4288 on periods that should have gone through VDP and assuming the disclosure is now on the record.
