Quick Answer
- The self-employed T1 filing deadline for the 2025 tax year in Canada was Monday, June 15, 2026.
- If you did not file by that date and you owe money, the CRA is now charging a late-filing penalty of five percent of the balance owing plus one percent for each full month the return is late, up to twelve months.
- Daily compound interest at the prescribed rate has been accruing on any unpaid balance since May 1, 2026, because the payment deadline was April 30 even though the filing deadline was June 15.
- File your T1 with the T2125 schedule immediately to stop the penalty clock.
- Then request taxpayer relief under Form RC4288 if the delay had a reason the CRA can accept.
Why this June 15 deadline is the one Canadians get wrong every year
June 15, 2026 came and went. If you file your Canadian personal taxes as self-employed as a freelancer, sole proprietor, gig worker, or partner in a partnership, that was your filing deadline for the 2025 tax year. Miss it and the CRA adds a late-filing penalty and daily compound interest on top of anything you already owed.
You are not alone. June 15 is the most misunderstood filing date in the Canadian tax calendar. The rule looks like a two-month extension, but any balance owing was actually due April 30, six weeks earlier, and that is where most of the cost sits.
This article gives you three things: a same-week filing path, a clear read on what the CRA is charging today, and the exact relief request to send if your delay had a reason the CRA can accept.

Five common scenarios and the immediate action
- →Sole proprietor with a balance owing: file the T1 with T2125 today and pay through CRA My Payment the same day.
- →Sole proprietor expecting a refund: file this week. No penalty applies without a balance, but your refund does not release until you file.
- →Spouse of a self-employed person who earns only salary: the June 15 extension applied to you too. File now.
- →Incorporated professional filing a personal T1 late: the personal return follows the personal deadline. File immediately.
- →Partnership member with a T5013 slip: file the T1 now and include the T5013 amounts.

| Scenario | Immediate action | Penalty exposure | Interest exposure |
|---|---|---|---|
| Sole proprietor with a balance owing | File the T1 and T2125 today; pay via CRA My Payment. | 5% + 1% per full month, up to 12 months. | Daily compound since May 1, 2026. |
| Sole proprietor expecting a refund | File this week; no balance to pay. | None while there is no balance owing. | None. |
| Spouse of a self-employed person (salary) | File this week; June 15 extension applied to you too. | Same as the self-employed partner. | None unless you owe a balance. |
| Incorporated professional (personal T1) | File personal T1 immediately; corporate T2 is separate. | 5% + 1% per month on personal balance. | Daily compound on personal balance since May 1. |
| Partnership member with a T5013 | File the T1 including T5013 amounts now. | 5% + 1% per month on personal balance. | Daily compound on personal balance since May 1. |
The dual-deadline trap — April 30 pays, June 15 files
Here is the rule that catches almost every self-employed filer at least once. The Income Tax Act sets two separate dates for people with self-employment income: the T1 is due June 15 the year after the tax year ends, and any balance owing is due April 30, the same payment date every other individual filer faces.
The consequence is straightforward. If you owed money for 2025 and did not pay by April 30, 2026, the CRA started charging daily compound interest at the prescribed rate on May 1. That clock has been running for months. Interest and the late-filing penalty are two separate charges: one is triggered by unpaid balance, the other by an unfiled return.
For the pre-deadline planning that would have avoided this, see our 2026 self-employed tax deadline guide.
What the CRA will actually charge you now
Work through an example. You owe $5,000 for the 2025 tax year and did not pay by April 30 or file by June 15. Two full months past June 15, the first-time penalty is five percent of $5,000 plus two months at one percent, that is $250 plus $100, or $350. Interest at the prescribed rate has also been running on the $5,000 since May 1.
A repeat late filer in the same position pays $700, ten percent of $5,000 plus two months at two percent. Repeat status typically applies where the CRA issued a formal demand to file in any of the three preceding tax years.

How to file your 2025 T1 and T2125 this week
-
1
Gather what you have Bank statements, invoices sent and received, credit-card statements, and any T4A slips issued to you as a contractor. You need enough to file an honest return, and missing receipts can be captured later through a T1 adjustment.
-
2
Complete Form T2125 Net business income flows to Line 13500 of the T1. Gross flows to Line 13499. Use the T2125 expense categories such as advertising, meals, home office, and vehicle, because those are the ones the CRA expects.
-
3
Attach the T2125 to your T1 and NETFILE Certified software transmits the return and schedule together. NETFILE stops the penalty clock the day the CRA accepts the return; paper filing adds weeks.
-
4
Pay the balance today Use CRA My Payment or online banking through a Canadian bank. For a fuller breakdown of the deductions the T2125 supports, see how self-employed Canadians work out deductions.
Taxpayer relief vs. voluntary disclosure — which one fits your situation
Two CRA programs can reduce what a late filer ends up paying. Both involve asking the CRA for leniency, but they cover different situations.
Taxpayer Relief is authorised under subsection 220(3.1) of the Income Tax Act. It gives the CRA discretion to cancel or waive penalties and interest in specific circumstances, including serious illness, a death in the family, a natural disaster, a CRA processing delay, or documented financial hardship. File Form RC4288 with supporting evidence. The CRA has a ten-year window to grant relief, and relief is discretionary, never guaranteed.
The Voluntary Disclosures Program is a separate track for taxpayers with unfiled returns or unreported income from earlier years who want to come forward before the CRA finds it. VDP uses Form RC199 and must be voluntary, complete, involve a potential penalty, and normally be at least one year past due.
For most self-employed filers who missed only the June 15, 2026 deadline, Taxpayer Relief is the applicable program, not VDP. If older unfiled years are involved, a structure review may be worth running at the same time. See sole proprietor vs. incorporated in Canada.
| Attribute | Taxpayer Relief | Voluntary Disclosures Program |
|---|---|---|
| Purpose | Cancel or waive penalty and interest for a specific reason. | Come forward with previously unfiled or unreported items. |
| Governing rule | Subsection 220(3.1), Income Tax Act | CRA administrative program (IC00-1R6) |
| Typical use case | Serious illness, family death, natural disaster, CRA delay, financial hardship. | Older unfiled returns or unreported income the CRA has not yet contacted you about. |
| Form required | RC4288 — Request for Taxpayer Relief | RC199 — Voluntary Disclosures Program Application |
| Penalty relief | May be cancelled or waived in full or in part. | May be waived if the application is accepted. |
| Interest relief | May be reduced within a 10-year look-back window. | Partial interest relief only. |
| Time limit | 10 years back from the date of the request. | Return normally must be at least one year past due. |
Common mistakes that make a late filing worse
Six patterns turn up again and again in the files that reach our desk after a missed June 15. Recognising them saves real money.
- →Delaying another month to gather every receipt. The penalty grows every full month. Filing this week with your best numbers, then adjusting later through a T1-ADJ, is almost always cheaper.
- →Assuming the June 15 filing extension also extended April 30. It never has. Interest has been running since May 1.
- →Filing the T1 without the T2125 attached. The CRA will reopen the return, and that reopens the penalty exposure.
- →Missing quarterly installment obligations exposed by the late return. Filers with net tax owing above $3,000, or $1,800 in Quebec, generally must remit quarterly.
- →Paper filing instead of NETFILE. Paper adds weeks, and every extra week potentially adds another one percent penalty band.
- →Assuming no balance owing means no consequences. It usually means no penalty, but the refund and any benefit payments will not release.
