CRA Tax Deadlines 2026 & 2027
Key filing and payment dates set by the Canada Revenue Agency for the 2025 and 2026 tax years, plus what it actually costs to miss one. Missing a deadline can trigger a late-filing penalty, daily-compounded interest, or an instalment penalty — the sections below walk through the exact amounts.

What it costs to miss a CRA deadline
Three separate charges can apply, and they stack: a late-filing penalty (only if you owe tax and file late), daily-compounded arrears interest (on any unpaid balance, whether or not you filed on time), and an instalment penalty (only for instalment payers who fall more than $1,000 short). Run your own numbers with the late-filing penalty calculator or the arrears interest calculator.
Late-filing penalty — only applies if you owe tax
| Situation | Penalty |
|---|---|
| First late return | 5% of your balance owing, plus 1% for each complete month late (up to 12 months — 17% maximum) |
| Repeat late filer | 10% plus 2% per complete month (up to 20 months — 50% maximum) — applies if CRA sent you a demand to file and penalized you in any of the prior 3 years |
No balance owing (including if you're due a refund) means no late-filing penalty at all, however late you file.
Arrears interest — applies to any unpaid balance
The CRA charges compound daily interest on tax that's still unpaid after the balance-due day, at its prescribed overdue-tax rate — currently 7% a year for Q3 2026 — reset every calendar quarter from the published quarterly rate (full history on our CRA prescribed interest rates page). Interest runs from the day after April 30, 2026 regardless of filer type — self-employment moves the filing date, never the payment date.
Instalment penalty — only if you're required to pay instalments
Missing or underpaying a required instalment triggers instalment interest at the same prescribed rate. A separate penalty only kicks in if that instalment interest for the year comes to more than $1,000 — the CRA then charges half the amount by which your interest exceeds the higher of $1,000 or 25% of the interest you'd have paid had you made no instalments at all. See the instalment interest & penalty calculator for your own figures.
Worked examples
Example 1 — $8,000 balance owing, filed and paid August 1, 2026
An individual owes $8,000 for 2025 but doesn't file or pay until August 1, 2026 — about 3 complete months after the April 30, 2026 deadline, and a first offence.
| Late-filing penalty (5% + 1% × 3 months) | $640 |
| Arrears interest (93 days at 7%, plus interest on the penalty) | $155 |
| Total owing (balance + penalty + interest) | $8,795 |
That's $795 added on top of the $8,000 tax itself — money that filing on time, even without paying, would have avoided almost entirely (only the interest would still apply).
Example 2 — self-employed, $6,000 balance, files and pays on June 15, 2026
A self-employed filer waits until their June 15, 2026 filing deadline to both file and pay a $6,000 balance — the mistake the June 15 date invites, because the filing extension does not extend the payment deadline.
- Late-filing penalty: $0 — filed by the self-employed deadline, so none applies.
- Arrears interest for 46 days (April 30, 2026 to June 15, 2026) at 7%: $53.
No penalty here because the return itself was filed on time — but the interest is real and entirely avoidable by paying the estimated balance by April 30, 2026, even while filing later.
The self-employed split: file June 15, pay April 30
This is the most misunderstood CRA date. If you or your spouse or common-law partner carried on a business in 2025, your filing deadline moves to June 15, 2026. But your payment deadline does not move — any balance owing is still due April 30, 2026, the same day as everyone else. Filing on the self-employed deadline with an unpaid balance means no late-filing penalty (because you filed on time for your filer type), but arrears interest still runs from April 30, 2026 the same as if you weren't self-employed at all. Example 2 above shows what that six-week gap actually costs. Estimate what you'll owe ahead of time with the self-employed tax buffer calculator so you can pay by April 30, 2026 even if you plan to file later.
Quarterly tax instalments
You have to pay tax by instalments during the year — instead of in one lump sum the following April — if your net tax owing is more than $3,000 ($1,800 for Quebec residents) in the current year and in either of the two prior years. "Net tax owing" is tax that wasn't already collected through withholding, which is why the requirement mostly catches self-employed workers, landlords, and retirees drawing pension or RRIF income without enough tax withheld at source. It's a two-year look-back, so most newly self-employed people don't receive an instalment reminder in their first year or two.
Instalments are due March 15, June 15, September 15 and December 15 every year (farmers and fishers pay a single instalment on December 31 instead). Skip one, pay late, or pay too little and the CRA charges instalment interest at its prescribed rate from the date each payment was due — and, if that interest for the year exceeds $1,000, an instalment penalty on top. Work out whether you're required to pay, and how much, with the quarterly instalments calculator.
RRSP contribution deadline
The RRSP contribution deadline is always 60 days after December 31 of the tax year — so it moves every year and doesn't line up with the T1 filing deadline. For the 2025 tax year, that's March 2, 2026. For the 2026 tax year, it's March 1, 2027. Contribute by the deadline and you can still deduct it on the earlier tax year's return, even though the contribution itself falls in the following calendar year — a two-month window that trips people up every RRSP season. There's no penalty for missing it; a contribution made after the deadline simply counts toward the next tax year instead. The only hard stop is December 31 of the year you turn 71 — the last day you can contribute to your own RRSP. Check how much room you have with the RRSP contribution room calculator, or see the tax savings from a contribution with the RRSP calculator.
Other things to know
NETFILE opens February 23, 2026. That's the earliest day the CRA accepts 2025 returns filed online — you can prepare your return earlier, but it won't be transmitted until then.
Weekend and holiday rule. When a due date falls on a Saturday, Sunday or a public holiday the CRA recognizes, your return is on time if it's received or postmarked by the next business day, and a payment is on time if received by the first business day after.
Quebec residents: file a separate provincial return — the TP-1 — with Revenu Québec in addition to your federal T1 return with the CRA. The provincial filing deadline matches the federal one (April 30, or June 15 for self-employed), and Quebec runs its own, lower instalment threshold of $1,800.

Frequently asked questions
What is the CRA deadline?
For most individuals, the main CRA deadline is April 30, 2026 — that's when your 2025 tax return must be filed and any balance owing must be paid. If you or your spouse or common-law partner are self-employed, the filing deadline moves to June 15, 2026, but the payment deadline stays April 30, 2026. Other CRA deadlines that recur every year include the RRSP contribution deadline (60 days after December 31), and quarterly tax instalments on March 15, June 15, September 15 and December 15 for anyone who owes more than $3,000 in tax two years running.
What is the CRA tax deadline for 2026?
The deadline to file your 2025 personal income tax return, and to pay any balance owing, is April 30, 2026. If you or your spouse or common-law partner were self-employed in 2025, your filing deadline is extended to June 15, 2026 — but any balance owing is still due April 30, 2026, regardless of filer type.
When are my taxes due in Canada?
Personal income tax returns are due April 30, 2026 for most Canadians, and payment of any balance owing is due the same day. Quebec residents file both a federal T1 return with the CRA and a provincial TP-1 return with Revenu Québec, on the same schedule. Corporations, trusts and GST/HST registrants run on different calendars tied to their own year-ends and reporting periods.
What happens if I file my taxes late with the CRA?
If you owe tax and file late, the CRA charges a late-filing penalty of 5% of your balance owing, plus 1% for every complete month you're late (up to 12 months). Repeat late-filers face double: 10% plus 2% per month, up to 20 months. Daily-compounded arrears interest (currently 7% a year) applies separately from the day after the balance-due day. If you're due a refund, there's no penalty for filing late — but you should still file to keep GST/HST credit, Canada Child Benefit and other payments flowing.
When is the RRSP contribution deadline?
The RRSP contribution deadline is always 60 days after December 31 of the tax year — March 2, 2026 for contributions counted against your 2025 tax year, and March 1, 2027 for contributions counted against your 2026 tax year. Contributions made by the deadline can be deducted on that year's return even though the deadline falls in the following calendar year. Miss it and the contribution simply counts toward the next tax year instead — there's no penalty, just a delayed deduction.
When are CRA tax instalments due?
Quarterly instalments are due March 15, June 15, September 15 and December 15 every year (farmers and fishers pay a single instalment on December 31 instead). You only have to pay them if your net tax owing is more than $3,000 ($1,800 if you live in Quebec) in the current year AND in at least one of the two prior years — so most newly self-employed people don't get caught until their second or third year of higher income.
What is a T1 return, and when is the 2025 T1 due?
T1 is the CRA's General Income Tax and Benefit Return — the form nearly every individual files each year. The 2025 T1 (covering income earned in the 2025 calendar year) is due April 30, 2026, or June 15, 2026 if you or your spouse or common-law partner were self-employed. NETFILE, the CRA's online filing system, opens for 2025 returns on February 23, 2026.
Can I get an extension on a CRA deadline?
The CRA does not grant blanket filing extensions the way some other tax agencies do. If you can't pay by the deadline, file on time anyway (that alone avoids the late-filing penalty) and then set up a payment arrangement. In genuine hardship situations — illness, natural disaster, CRA error — you can request taxpayer relief to have penalties or interest cancelled, but this is discretionary and decided case by case, not an automatic extension.
