The Canadian tax deadline is really three dates: the day the return is due, the day any tax owing must be paid, and the RRSP contribution cut-off that feeds into the return. For most people the first two are the same day, April 30. The tables below list every personal CRA tax deadline the Canada Revenue Agency has published for the 2025 tax year, filed in 2026, followed by the dates already known for the 2026 tax year.
How to read this table: the filing date and the payment date are separate deadlines. The June 15 date only moves the filing date; tax owed by a self-employed person was still due April 30, 2026.

When is the tax filing deadline in Canada for 2026?
For the 2025 tax year, the CRA’s deadline to file was Thursday, April 30, 2026, and the deadline to pay any balance owing was the same day. The CRA’s wording on its filing page is that “for most people,” the return has to be filed on or before April 30 and payment is due April 30.
That date is not new each year. Section 150(1)(d) of the Income Tax Act sets an individual’s filing date as the following April 30, and the definition of “balance-due day” in section 248(1) sets payment for individuals at April 30 of the following year. The CRA publishes the calendar dates, but the rule itself only changes if Parliament changes the Act.
If April 30, 2026 has passed and a 2025 return is still unfiled, it can still be sent. NETFILE accepts initial 2025 returns until January 29, 2027, and returns for 2018 to 2024 as well. What changes after the deadline is the cost: a penalty if tax is owed, interest on anything unpaid, and possible gaps in benefit payments. Those are covered further down.
What is the tax deadline for self-employed people in Canada?
The self-employed filing deadline for the 2025 tax year was Monday, June 15, 2026. It applies to anyone who carried on a business in 2025, and to a spouse or common-law partner who lived with them, even if the spouse only had employment income.
Two limits catch people out:
- Payment is still due April 30. The CRA’s filing page adds that anyone with a balance owing for 2025 had to pay it on or before April 30, 2026. A sole proprietor who files on June 15 and pays that day is charged interest from May 1.
- Tax-shelter businesses do not get June 15. If the business spending related mostly to a tax shelter investment, the 2025 return was due April 30, 2026.
Self-employed people with a large balance owing each spring often end up paying instalments too, which is the next set of deadlines on this page. The income tax calculator gives a rough idea of the tax on a given level of business profit before the return is done.
What happens if a tax deadline falls on a weekend or holiday?
The CRA applies the same rule to personal filing and payment due dates. When a due date falls on a Saturday, Sunday or a public holiday the CRA recognizes:
- a return is on time if the CRA receives it, or it is postmarked, on or before the next business day;
- a payment is on time if it is received on the first business day after the due date.
The next-business-day shift mattered twice in 2026. The RRSP deadline for the 2025 tax year is 60 days after December 31, 2025, which was Sunday, March 1, 2026, so the CRA published Monday, March 2, 2026. The first instalment date, March 15, 2026, was also a Sunday, so a payment received Monday, March 16 counted as on time. April 30, 2026 and June 15, 2026 fell on a Thursday and a Monday, so the filing deadlines did not move.
When is the RRSP deadline for the 2025 and 2026 tax years?
The last day to make RRSP, pooled registered pension plan (PRPP) or specified pension plan (SPP) contributions that can be deducted on the 2025 return was March 2, 2026. The CRA’s line 20800 page asks paper filers to attach receipts for contributions made from March 4, 2025 to March 2, 2026 to the 2025 return.
For the 2026 tax year, section 146(5) of the Income Tax Act allows a deduction for premiums paid “on or before the day that is 60 days after the end of the year,” which works out to Monday, March 1, 2027. The CRA had not posted that date on September 30, 2026. The RRSP deadline guide covers deduction room, spousal RRSPs and what happens with contributions made after the cut-off.
Two related deadlines sit beside it:
- Excess contributions. Anyone who over-contributed in 2025 had to file and pay the T1-OVP return by March 31, 2026.
- TFSA tax. If tax applies on a TFSA, for example on an over-contribution, the filing and payment deadline is June 30 of the following year, which was June 30, 2026 for 2025.
What are the tax instalment due dates for 2026?
Instalments are payments made during the year toward the tax that would otherwise be due in one lump sum on April 30. The CRA may ask for them when your net tax owing is more than $3,000 (more than $1,800 for Quebec residents) for 2026 and for either 2025 or 2024. It sends reminders to the people who need to pay.
How to read this table: farmers and fishers whose main income is from farming or fishing pay once a year, by December 31. Instalments due on or after the date of a person's death do not have to be paid.
| Due date | Day of the week | Payment on time if received by |
|---|---|---|
| March 15, 2026 | Sunday | Monday, March 16, 2026 (next business day) |

Late or short instalments are charged instalment interest. A separate instalment penalty is added only if the instalment interest for 2026 is more than $1,000. The same four dates, March 15, June 15, September 15 and December 15, apply each year.
What happens if you file your taxes late in Canada?
The penalty depends on whether you owe tax. The CRA’s late-filing penalty is a percentage of the balance owing on the late return, so a return with a refund or a zero balance attracts no penalty. When there is a balance, the charges are:
How to read this table: percentages are of the balance owing on the late return. The repeated penalty applies if the CRA charged a late-filing penalty in one of the three previous tax years and sent a demand to file.
| Penalty | Charged at once | Plus, per full month late | Up to (months) |
|---|---|---|---|
| Late-filing penalty | 5% | 1% | 12 |
| Repeated late-filing penalty (penalized in one of the 3 prior years and sent a demand to file) | 10% | 2% | 20 |

Interest is charged on top, compounded daily from the day after the due date until the balance is paid, including amounts that come from a reassessment. The CRA resets its prescribed rates every three months:
How to read this table: the overdue-taxes rate is interest on unpaid amounts; the late-filing penalty is a separate charge. Rates for 2027 quarters are announced by the CRA shortly before each quarter starts.
| Interest | Annual rate |
|---|---|
| Interest the CRA charges on overdue taxes, CPP contributions and EI premiums | 7% |
| Interest the CRA pays individuals on overpayments | 5% |

A worked example, using hypothetical figures: someone owes $2,000 on a 2025 return filed on October 15, 2026. The return is five full months late (May to September), so the late-filing penalty is 10% of the balance, or $200, before interest. Filing on April 30 without paying would have avoided that $200 completely; only interest would have applied.
Late filing also affects money coming in. The CRA uses the return to set the Canada Groceries and Essentials Benefit (formerly the GST/HST credit), the Canada child benefit and related provincial payments, and it names Old Age Security among the benefits a late return can disrupt. The Canada Groceries and Essentials Benefit guide and the OAS guide explain how each one uses the return, and the Canada workers benefit advance payments need the return to reach the CRA before November 1.
What if you cannot pay your taxes by April 30?
File by the deadline anyway. The CRA’s own advice on its penalties page is to file on time even when you cannot pay, because the late-filing penalty is avoided and only interest applies. Then:
- Pay what you can by April 30. Interest only runs on the unpaid part. The CRA generally does not charge a difference of $2 or less.
- Use one of the CRA’s payment options. The CRA accepts electronic payments, a cheque or debit at a Canadian bank or credit union with a remittance voucher, and cash or debit at a Canada Post outlet (for a fee) with a QR code.
- Ask about a payment arrangement. The CRA’s debt collection pages explain how to spread a balance over time. Interest keeps compounding until the balance is paid in full.
- Ask for relief if something outside your control happened. The CRA can cancel or waive penalties or interest when circumstances beyond your control prevented you from meeting your tax obligations. Requests have to be made within a 10-year period ending in the calendar year of the request.
What are the tax deadlines for special situations?
Some returns follow different dates. The CRA’s rules for the most common ones:
How to read this table: when a filing date moves because of a death, a surviving spouse's balance owing for the previous year is still due April 30 to avoid interest.
| Situation | File by | Pay by |
|---|---|---|
| Death between January 1 and October 31 | April 30 of the following year | Same as filing date |
| Death between November 1 and December 31 | 6 months after the date of death | Same as filing date |
| Death January 1 to December 15, and the person or their cohabiting spouse was operating a business on the date of death | June 15 of the following year | Payment due date does not change |
| Death on or before the previous year's filing due date, with that return not yet filed | 6 months after the date of death (previous-year return) | Same as filing date |
| Non-resident filing a Canadian return | April 30 of the year after the tax year (June 15 if the person or their spouse carried on a business in Canada) | April 30 of the year after the tax year |
| Estate or trust (T3 return) | 90 days after the trust's tax year-end | Same as filing date |
| Tax-shelter business | April 30 (no June 15 extension) | April 30 |

The estate side of a death, including whether Canada has an inheritance tax and what the final return reports, is covered in the inheritance tax in Canada guide. Newcomers who arrived partway through the year use the normal April 30 date for their first return; the first Canadian tax return guide for newcomers walks through what that return includes. Quebec residents also file a separate provincial return with Revenu Québec, which sets its own rules and is not covered in the tables on this page.
When is the tax deadline for the 2026 tax year?
The 2026 tax year runs from January 1 to December 31, 2026, and the return for it is filed in 2027. Applying the Income Tax Act’s fixed dates:
- Filing and payment: Friday, April 30, 2027.
- Self-employed filing: Tuesday, June 15, 2027, with payment still due April 30, 2027.
- RRSP contributions for 2026: by Monday, March 1, 2027.
- Instalments toward 2026 tax: March 15, June 15, September 15 and December 15, 2026, as published by the CRA.
The CRA announces the NETFILE opening date for each new filing season; for 2025 returns it opened on February 23, 2026. This page is updated when the CRA posts its pages for the 2026 return, and any change shows in the tables at the top.
How do you file before the deadline?
Most people file online through NETFILE with CRA-certified tax software, which also shows the balance owing or refund before the return is sent. Free certified options exist, and the guide to free tax software in Canada compares them; the Wealthsimple Tax review looks at one pay-what-you-want option in detail.
Before filing, three checks save most corrections later:
- Match every slip. Certified software can import the slips the CRA already has on file; compare them with the slips received by mail or email before sending the return.
- Check the RRSP deduction limit on the latest notice of assessment before claiming RRSP contributions.
- Estimate the balance early. The Canada tax brackets for 2026 show the rate that applies to each extra dollar of income, and the capital gains tax calculator estimates the tax on investments sold during the year.
Common mistakes with Canadian tax deadlines
- Treating June 15 as the payment date. It is a filing extension only. Tax owed by the self-employed is due April 30.
- Not filing because you cannot pay. Filing late adds a penalty on top of interest; filing on time without paying adds only interest.
- Not filing because income was low or you expect a refund. There is no penalty, but benefits and credits based on the return can stop until it is assessed.
- Missing the RRSP cut-off. A contribution made after the 60-day window counts toward the next tax year, not the one being filed.
- Assuming the weekend rule applies to everything. It moves a due date only when that date itself is a Saturday, Sunday or CRA-recognized holiday.
- Ignoring instalment reminders. Skipping instalments leads to instalment interest, even if the full balance is paid on April 30.
- Filing a deceased person’s return on the normal schedule. Deaths in November and December get a 6-month window instead.
