The calculator below is an estimate, not a CRA assessment. CRA's actual account calculation controls. Prescribed interest rates are set quarterly, and a taxpayer's actual account can involve reassessments, payments, instalments, different tax periods, adjustments or other factors.
CRA Late-Filing Penalty & Interest Estimator
Estimate the late-filing penalty and known 2026 daily-compounded interest for a 2025 personal income-tax balance. The calculator uses published 2026 CRA arrears rates and does not invent an unpublished future rate.
Late filing and/or overdue payment
Most individuals had to file and pay their 2025 balance by April 30, 2026.
| Filing deadline | April 30, 2026 |
|---|---|
| Payment deadline | April 30, 2026 |
| Late-filing penalty | $400.00 |
| Estimated known-rate interest | $117.23 |
| Estimated total account balance | $5,517.23 |
Penalty formula used: 5% + 1% for each full month late, capped at 12 months
2026 CRA deadlines at a glance
| Taxpayer | 2025 return filing deadline | Balance-payment deadline |
|---|---|---|
| Most individuals | April 30, 2026 | April 30, 2026 |
| Self-employed individuals and applicable spouses/ common-law partners | June 15, 2026 | April 30, 2026 |
The June 15 deadline is a filing extension for eligible self-employed taxpayers. It does not move the balance-payment deadline from April 30. Interest can therefore accrue even when the return is filed by June 15.
How the CRA late-filing penalty works
For a return with a balance owing, the ordinary late-filing penalty is 5% of the balance owing plus 1% of that balance for every full month the return is late, up to a maximum of 12 months.
Ordinary late filing
5% of the balance owing plus 1% for each full month late, capped at 12 months.
Repeated late filing
A higher penalty can apply where the CRA's specified previous-year and demand-to-file conditions are met. It can reach 20 months.
CRA prescribed interest in 2026
CRA's prescribed interest rates are set quarterly. For income tax arrears, the published 2026 rate is 7% for the first, second and third calendar quarters. Interest on overdue income-tax amounts is compounded daily.
| Period | Income-tax arrears rate |
|---|---|
| January 1–March 31, 2026 | 7% per year |
| April 1–June 30, 2026 | 7% per year |
| July 1–September 30, 2026 | 7% per year |
The CRA sets prescribed rates quarterly. Check the official CRA rate table for the applicable quarter instead of assuming that the current rate will remain unchanged.
Taxpayer relief: cancelling or waiving penalties and interest
CRA may cancel or waive penalties and interest when circumstances beyond your control prevented you from meeting your tax obligations. CRA considers requests case by case; eligibility does not guarantee approval.
Circumstances that may support a request
- Natural or human-made disasters.
- Serious disruptions to services or other extraordinary circumstances.
- Other circumstances that prevented you from meeting your tax obligations despite reasonable efforts.
How to apply
You can request taxpayer relief through CRA online services, or use Form RC4288, Request for Taxpayer Relief – Cancel or Waive Penalties and Interest. Explain the circumstances, identify the periods and amounts involved, and provide supporting documentation where relevant.
CRA Voluntary Disclosures Program (VDP)
The VDP is separate from a standard late-filing penalty waiver request. It is intended for taxpayers and registrants who voluntarily come forward to correct errors or omissions in their tax affairs.
Correct past errors
The program can apply to eligible previous omissions or errors.
Relief is possible
Eligible applications can receive penalty and partial interest relief under the current program.
Taxes still apply
VDP relief does not eliminate the underlying tax owing.
The current VDP rules took effect October 1, 2025. CRA identifies eligibility conditions, different relief levels, and a case-by-case review process. A taxpayer who is unsure whether the VDP is appropriate can use CRA's pre-disclosure discussion option.
