RC4288 Taxpayer Relief Calculator Canada (2026): Build a Better Request

This tool is a request-preparation worksheet, not an approval calculator. CRA decides taxpayer-relief requests using the facts in the file, the relevant tax or reporting period, the supporting documents, and its statutory discretion.

What the worksheet can show

It can help you organize the balance, debt type, age of the account, reason for the request, and evidence you may need. It can also show an illustrative penalty ceiling where the applicable rule is known. It cannot predict the amount CRA will waive, assign an approval probability, or calculate interest accurately from one balance and one annual rate because rates and accrual periods vary.

Evidence checklist

• the CRA notice, account statement, and affected tax years or reporting periods;
• a clear timeline of what prevented compliance or caused the delay;
• medical, employment, disaster, CRA-correspondence, or financial documents that support the timeline;
• a specific request identifying the penalties or interest and the period involved;
• a separate plan for the principal balance and any active collection action.

The CRA’s Taxpayer Relief Provisions explain the discretionary framework and rolling time limits. CRA’s Taxpayer Bill of Rights also describes the 10-calendar-year limit.

If CRA is already garnishing income, redirecting a refund or benefit, or restricting an account, treat the notice as urgent and contact CRA using the number on the notice. A Licensed Insolvency Trustee, tax professional, or tax lawyer can compare taxpayer relief with the other options that may apply to the underlying debt.
