CRA Tax Deadlines & Penalties Guide 2026
Understand the 2026 deadlines for filing 2025 returns, paying balances, making instalments, filing deceased-person and corporate returns, and requesting relief from CRA penalties and interest.
1. First: identify which tax year the 2026 deadline belongs to
Most dates discussed during the 2026 filing season are deadlines for the 2025 Canadian income tax return. For most individuals, the 2025 T1 return and any 2025 balance owing are due April 30, 2026. A qualifying self-employed person generally has until June 15, 2026 to file, but any 2025 balance owing remains due April 30, 2026. The 2026 tax return itself will generally be filed in 2027.
| Tax period | Most individuals | Qualifying self-employed | Balance owing |
|---|---|---|---|
| 2025 return filed in 2026 | April 30, 2026 | June 15, 2026 | April 30, 2026 |
| 2026 return filed in 2027 | Generally April 30, 2027 | Generally June 15, 2027 | Generally April 30, 2027 |
2. 2025 T1 filing and payment deadlines occurring in 2026
CRA's 2026 filing-season deadlines apply to the 2025 income tax and benefit return. Most individuals must file and pay by April 30, 2026. If the taxpayer or their spouse or common-law partner carried on a qualifying business in 2025, the filing deadline is generally June 15, 2026, although the balance owing must still be paid by April 30 to avoid interest.
Key Framework Highlights:
- The self-employed June 15 rule does not delay the balance-due date.
- Filing on June 15 while paying on April 30 can avoid late-payment interest when the required payment is made on time.
- If a due date falls on a Saturday, Sunday or CRA-recognized public holiday, CRA generally treats filing or payment as on time when completed on the next business day under its due-date rules.
| Taxpayer situation | 2025 return filing deadline | 2025 balance payment deadline | Important qualification |
|---|---|---|---|
| Most individuals | April 30, 2026 | April 30, 2026 | Standard individual deadline |
| Qualifying self-employed individual | June 15, 2026 | April 30, 2026 | June 15 is a filing deadline, not a payment extension |
| Spouse/common-law partner of qualifying self-employed taxpayer | June 15, 2026 where CRA's conditions are met | April 30, 2026 | The filing extension can apply to the spouse/common-law partner who lived with the self-employed taxpayer |
| Self-employed person with business expenditures primarily relating to a tax-shelter investment | April 30, 2026 | April 30, 2026 | The ordinary June 15 filing extension does not apply |
3. Late-filing penalties for the 2025 return
If a 2025 return is filed late and tax is owing, CRA generally charges a late-filing penalty of 5% of the 2025 balance owing plus 1% of that balance for each full month the return is late, up to 12 months. If the statutory repeated-late-filing conditions are met, the penalty can instead be 10% plus 2% per full month, up to 20 months.
Key Framework Highlights:
- The ordinary maximum is effectively 17% of the balance owing.
- The repeated-late-filing maximum is effectively 50% of the balance owing.
- The repeated penalty is not triggered merely because someone filed any previous return late; CRA's statutory prior-year and demand conditions must be satisfied.
- Filing on time is important even when payment cannot be made in full because filing late can create a penalty in addition to interest on the unpaid balance.
- If there is no balance owing, the ordinary balance-based late-filing penalty does not arise, although other penalties or filing consequences can apply to other types of non-compliance.
| Penalty | Rate | Maximum period | Key condition |
|---|---|---|---|
| Ordinary late-filing penalty | 5% of balance owing + 1% per full month | 12 months | Return filed late and tax is owing |
| Repeated late-filing penalty | 10% of balance owing + 2% per full month | 20 months | Prior late-filing penalty in a qualifying prior year and CRA demand-to-file conditions |
4. CRA interest on unpaid balances
CRA charges compound daily interest on overdue tax balances beginning the day after the payment due date. The prescribed rate changes quarterly. For July 1 through September 30, 2026, CRA's prescribed annual interest rate on overdue income-tax balances is 7%.
Key Framework Highlights:
- CRA updates prescribed interest rates every three months.
- Overdue income tax interest is compounded daily.
- Interest generally begins the day after the payment due date.
- Interest can continue until the outstanding amount is paid.
- The interest rate should be updated whenever this page is used as a live calculator because quarterly rates can change.
| Period in 2026 | Prescribed annual rate on overdue income tax | Interest convention |
|---|---|---|
| January 1 to March 31, 2026 | 7% | Prescribed rate for the quarter |
| April 1 to June 30, 2026 | 7% | Prescribed rate for the quarter |
| July 1 to September 30, 2026 | 7% | Prescribed rate for the quarter |
5. 2026 tax-instalment deadlines
Some individuals must make instalment payments during 2026 instead of paying all of their expected tax after year-end. CRA generally requires instalments when net tax owing exceeds $3,000 for the relevant years, or $1,800 for Quebec residents, under the applicable current and prior-year tests. For most individuals, the 2026 instalment dates are March 15, June 15, September 15 and December 15.
Key Framework Highlights:
- Farmers and fishers with farming or fishing as their main source of self-employment income generally have a single December 31 instalment date.
- Missing or underpaying required instalments can produce instalment interest and a possible instalment penalty.
- Instalment payments are different from the April 30 balance-due date for the preceding year's tax return.
| 2026 instalment | Due date | General treatment |
|---|---|---|
| First instalment | March 15, 2026 | Quarterly personal income-tax instalment |
| Second instalment | June 15, 2026 | Quarterly personal income-tax instalment |
| Third instalment | September 15, 2026 | Quarterly personal income-tax instalment |
| Fourth instalment | December 15, 2026 | Quarterly personal income-tax instalment |
6. Deceased taxpayer deadlines
The final return of a deceased taxpayer follows special deadlines. If death occurred from January 1 through October 31, the final return and any balance owing are generally due April 30 of the following year. If death occurred from November 1 through December 31, the final return and balance are generally due six months after the date of death. Additional special rules apply where the deceased person or their spouse/common-law partner was self-employed.
| Date of death | General final-return filing deadline | General payment deadline |
|---|---|---|
| January 1 to October 31 | April 30 of the following year | Same deadline |
| November 1 to December 31 | Six months after the date of death | Same deadline |
| Self-employed deceased person or qualifying self-employed spouse/common-law partner | Special June 15 or six-month rule depending on the date of death and statutory conditions | Special rules apply; check CRA's deceased-person guidance |
7. Corporate T2 deadlines
A corporation generally has six months after the end of its tax year to file its T2 return. The balance-due date is generally two months after the fiscal year-end, but a qualifying Canadian-controlled private corporation can generally have three months to pay its balance where the statutory conditions are satisfied.
| Corporate obligation | General deadline | Important qualification |
|---|---|---|
| T2 filing | Six months after fiscal year-end | Applies regardless of whether tax is owing |
| Corporate balance owing | Generally two months after fiscal year-end | Earlier than the T2 filing deadline |
| Qualifying CCPC balance owing | Generally three months after fiscal year-end | Available only when statutory conditions are satisfied, including the relevant small-business-deduction conditions |
| Corporate instalments | Monthly or quarterly depending on the corporation | Separate instalment rules apply |
8. Taxpayer relief and Form RC4288
CRA's taxpayer-relief provisions can allow cancellation or waiver of penalties and interest where circumstances beyond the taxpayer's control prevented compliance or justify relief under the applicable administrative and statutory rules. Examples can include serious illness, extraordinary circumstances, CRA errors, financial hardship in qualifying situations and other circumstances considered under CRA's taxpayer-relief policy. Relief is discretionary and is not automatic.
Key Framework Highlights:
- Form RC4288 is titled 'Request for Taxpayer Relief - Cancel or Waive Penalties and Interest'.
- Taxpayer-relief requests can be submitted online through CRA's digital services or using Form RC4288.
- CRA's discretion generally extends only to periods ending within the 10 calendar years before the year in which the request is made.
- The taxpayer should explain the circumstances, provide supporting evidence and identify the specific penalties or interest for which relief is requested.
- A request for relief does not automatically stop collection activity or guarantee cancellation.
- CRA can consider fairness and the taxpayer's compliance history when determining relief.
| Relief question | Correct principle |
|---|---|
| Can serious illness justify relief? | It can be relevant when it prevented or impaired compliance, subject to CRA's assessment. |
| Can CRA error be relevant? | Yes, CRA error or delay can be considered under the taxpayer-relief provisions. |
| Is there a 10-year limit? | Yes. CRA's discretion is generally limited to periods ending within 10 calendar years before the request year. |
| Is relief automatic? | No. CRA evaluates the request under the applicable taxpayer-relief provisions. |
9. Filing versus paying: a practical priority order
When a taxpayer cannot complete both actions by the deadline, filing the return on time should generally be prioritized even if the full balance cannot be paid. A late return can trigger a late-filing penalty when tax is owing, while unpaid tax can separately accumulate daily compound interest.
Action Checklist:
- File the return by the applicable filing deadline even if the full balance cannot be paid.
- Pay as much of the balance as possible by the payment due date.
- Review CRA's payment-arrangement options if the balance cannot be cleared immediately.
- Continue monitoring interest and penalties after the due date.
- Do not confuse the filing deadline with the payment deadline.
10. Weekend and public-holiday deadline rule
When a CRA filing or payment due date falls on a Saturday, Sunday or a public holiday recognized by CRA, CRA's current guidance generally treats the return as filed on time when it is received or postmarked by the next business day, and a payment as on time when received on the first business day after the due date.
Key Framework Highlights:
- Check the calendar rather than assuming that April 30 always means the last calendar day without adjustment.
- The treatment of filing and payment dates can differ slightly in CRA's administrative wording.
- Use CRA's current due-date page for the specific year when a deadline is close to a weekend or public holiday.
11. Electronic filing and payment
CRA offers electronic filing and several electronic payment methods. Online filing can help taxpayers meet deadlines and receive assessments or refunds faster, but using CRA's digital services does not itself extend a statutory due date.
Action Checklist:
- File through an authorized electronic method such as NETFILE when eligible.
- Use CRA My Account to monitor assessments, balances, instalments and payment history.
- Use a CRA-supported electronic payment method when possible.
- Keep proof of filing and payment.
- Do not assume that a bank processing delay extends the CRA deadline; allow enough time for the payment to reach CRA.
12. 2026 deadline examples
| Scenario | Applicable date | Reason |
|---|---|---|
| Employee with ordinary 2025 T1 return | File and pay by April 30, 2026 | Standard individual deadline |
| Self-employed taxpayer with qualifying 2025 business income | File by June 15, 2026; pay balance by April 30, 2026 | June 15 filing extension does not extend the payment date |

| 2026 personal instalment taxpayer | March 15, June 15, September 15 and December 15, 2026 | Quarterly instalment schedule |
| Corporation with December 31, 2025 year-end | T2 generally due June 30, 2026; balance generally due February 28, 2026, or May 31, 2026 for a qualifying three-month CCPC case | Six-month filing deadline and separate balance-due rule |
| Person dies on November 20, 2025 | Final return generally due May 20, 2026 | Six-month rule for deaths from November 1 through December 31 |
13. 2026 tax-deadline decision framework
Action Checklist:
- Identify the tax year: a deadline occurring in 2026 can relate to the 2025 return.
- Determine the taxpayer type: individual, self-employed individual, deceased taxpayer, corporation, partnership or trust.
- Separate filing deadline from balance-payment deadline.
- Check whether the taxpayer is required to make 2026 instalments.
- For a late individual return, determine whether tax is owing before calculating the ordinary 5% + 1% penalty.
- Check whether the repeated-late-filing penalty conditions are actually satisfied before applying 10% + 2%.
- Calculate interest separately from penalties using the prescribed quarterly rate applicable to the overdue period.
- For a deceased taxpayer, identify the death date and self-employment circumstances before selecting the deadline.
- For a corporation, determine both the six-month T2 filing deadline and the two- or three-month balance-due deadline.
- If circumstances beyond the taxpayer's control caused the problem, consider taxpayer relief and the 10-year request window.
