The Short Answer: Two Deadlines Every Self-Employed Canadian Must Know
- Self-employed Canadians and sole proprietors must pay any balance owing to the CRA by April 30, 2026, even though the T1 return filing deadline is June 15, 2026.
- Missing the April 30 payment deadline triggers CRA interest charges at the prescribed rate from May 1, even if the return is filed on time by June 15.
- A late T1 filing after June 15 carries a penalty of 5 percent of the balance owing plus 1% per month for up to 12 months; the penalty may double to 10% plus 2% per month for repeat late filers.
- Self-employment income is reported on Schedule T2125 (the CRA form where you report what your business earned and spent) and attached to the T1 return; net self-employment income appears on Lines 13499 and 13500.
- Self-employed individuals with net tax owing of $3,000 or more in the current or either of the two preceding tax years are generally required to make quarterly instalment payments to the CRA.
Why April 30 Catches So Many Self-Employed Canadians Off Guard
Picture this: it is April 29. You know your tax filing deadline is June 15, so you have been relaxed about getting your return together. Then a friend mentions — almost in passing — that the payment deadline is tomorrow. Not June 15. Tomorrow.
That moment of realization hits thousands of Canadian freelancers, consultants, and sole proprietors every spring. The June 15 filing extension for self-employed individuals is real and useful. What it does not do is extend the deadline for paying any taxes you owe. That date stays firmly at April 30 — the same as every other Canadian T1 filer.
If you are reading this because you are unsure about your deadlines, you are in the right place. This guide covers both critical dates, explains exactly what you owe and when, walks you through the filing process step by step, and tells you what to do if you are already past a deadline.

Established self-employed person with instalments already set up — Head straight to the common mistakes section to make sure you are not leaving deductions on the table or triggering penalties you could avoid.
Wondering whether to incorporate your business — The tax rules change significantly once you incorporate. Read our guide on being self-employed or incorporated in Canada before you make that decision.
Past the deadline — Skip to the closing section for the three immediate steps that can limit your exposure to penalties and interest.
Sole Proprietor vs. Employee vs. Incorporated: How Tax Deadlines Differ
The table below shows exactly how the three most common filer types compare across key tax obligations. Study the Sole Proprietor column — that is what applies to you as a freelancer or self-employed business owner.
| Obligation | Sole Proprietor | T4 Employee | Corporation (CCPC) |
|---|---|---|---|
| T1 Filing Deadline | June 15 | April 30 | 6 months after fiscal year-end |
| Balance Owing Deadline | April 30 | N/A — withheld at source | 3 months after year-end (CCPC) |
| Instalment Obligation | Yes — if net tax ≥$3,000 | No | Yes — if corporate tax ≥$3,000 |
| HST/GST Registration | Required at $30,000 | No | Required at $30,000 |
| Who Prepares Return | T1 + Schedule T2125 | Employer issues T4 slip | T2 corporate return + accountant recommended |
The key takeaway from that comparison: employees never think about instalments or HST registration because their employer handles source deductions. Self-employed individuals and corporations do not have that cushion. Every tax obligation falls on you — or your accountant — to track, calculate, and remit on time.
Your Self-Employed Tax Filing Roadmap: Six Steps from Receipts to CRA
-
1
Gather your income records and T4A slipsCollect every source of business income from the calendar year — invoices, payment receipts, and any T4A slips (information slips that payers issue when they pay a contractor or self-employed person $500 or more). If you do not have a T4A but know you were paid by a client, that income still needs to be reported. Cross-reference your bank statements if you are unsure.
-
2
Complete Schedule T2125 — your business income formSchedule T2125 (the Statement of Business or Professional Activities) is the CRA form where you report your gross business income and your allowable expenses. The result is your net self-employment income, which flows to Line 13499 (gross) and Line 13500 (net) on your T1 return. You fill out one T2125 for each type of business activity you carry on.
-
3
Calculate and claim your allowable business deductionsThe CRA allows you to deduct expenses that were reasonable in amount and incurred to earn business income. Common deductions include home office expenses, vehicle costs, meals and entertainment (subject to a 50 percent limit), and professional development. Each category has its own rules. Keep every receipt; the CRA can request documentation at any time.
-
4
Determine whether you are required to pay instalmentsIf your net tax owing is $3,000 or more in the current tax year, and was $3,000 or more in either of the two previous years, the CRA generally requires you to make quarterly instalment payments (in Quebec, the threshold is $1,800). Instalments are due on March 15, June 15, September 15, and December 15. Missing instalments may trigger instalment interest charges.
-
5
Pay any balance owing by April 30, 2026Once you know your net tax owing, subtract any instalments already paid. If the result is positive, you owe that amount to the CRA by April 30, 2026. You can pay through online banking, through My Account on the CRA website, or in person at a financial institution. Do not wait until you file your return — interest begins accruing on any unpaid balance from May 1.
-
6
File your T1 return by June 15, 2026Self-employed individuals and their spouses or common-law partners have until June 15 to file the T1 return. File with Schedule T2125 and any other required schedules attached. Filing electronically through NETFILE is the fastest method. Even if you cannot pay the full balance owing, always file on time — the late-filing penalty applies to the return itself, not just to the payment.
What You Can Deduct: The Self-Employed Expenses the CRA Allows
The CRA requires that deductions meet one standard: the expense must be reasonable in amount and incurred for the purpose of earning business income. Here are the categories that matter most for most sole proprietors in Ontario:
- Home Office Expenses (Form T777) — If you work from home, you can deduct a portion of your rent or mortgage interest, utilities, internet, and maintenance costs proportional to the space used for business. Sole proprietors must use the detailed method. See our guide on the home office tax deduction in Canada for a full calculation walkthrough.
- Vehicle Expenses — You can deduct the business-use portion of fuel, insurance, maintenance, parking, and loan interest or lease payments. You must keep a logbook recording every trip, the distance driven, and the business purpose. Without a logbook, the CRA can deny the entire vehicle deduction.
- Meals and Entertainment (50 Percent Rule) — Business meals and client entertainment are deductible, but only at 50 percent of the actual cost. So a $100 business lunch generates a $50 deduction.
- Business-Use Phone and Internet — The business-use percentage of your monthly phone and internet bills is deductible. Keep monthly statements as documentation.
- Professional Development and Dues — Courses, certifications, conferences, and professional association fees are generally deductible if they directly relate to your current business activities.
- Advertising and Marketing — Website costs, social media advertising, business cards, and promotional materials are deductible business expenses.

Do You Need to Collect HST? The $30,000 Threshold Explained
Once your cumulative business revenues pass $30,000, you must register with the CRA within 29 days. From that point, you are required to charge 13% HST on your taxable supplies in Ontario (made up of the 5 percent federal GST and the 8 percent Ontario provincial component), remit the amounts collected to the CRA, and file HST returns on a schedule determined by your annual revenue.
If your freelance income passed $30,000 at any point during 2025, you were required to register for HST and begin charging it on invoices issued after that point. Late registration can result in CRA assessments for the HST you should have collected but did not.
Registering voluntarily before you hit the threshold can actually save you money. As a registrant, you can claim Input Tax Credits (ITCs) — which means the CRA refunds the HST you paid on eligible business purchases. Note that HST obligations exist separately from your T1 obligations and have their own filing deadlines. If you operate in Quebec, Alberta, or other provinces, the sales tax structure and rates differ from Ontario's HST.
Seven Mistakes Self-Employed Canadians Make at Tax Time (and How to Avoid Them)
- Mistake 1: Confusing the June 15 filing date with the April 30 payment date. The June 15 extension gives you more time to submit your return — not more time to pay. File as early as you can so you know what you owe with enough time to pay without interest.
- Mistake 2: Not keeping a vehicle logbook. Without a mileage logbook recording each business trip, the CRA may disallow your vehicle deduction entirely. Use a mileage-tracking app or carry a small notebook in your glove compartment.
- Mistake 3: Missing or late HST registration. Many self-employed individuals do not realize they have crossed the $30,000 threshold. Check your cumulative revenue quarterly. Registering late means the CRA can assess you for the HST you should have collected from clients.
- Mistake 4: Skipping instalment payments and being surprised by interest. If you owe $3,000 or more in net taxes and did not pay instalments, the CRA will charge instalment interest — even if you pay your full balance by April 30. Set aside roughly 25 to 30 percent of each payment you receive throughout the year.
- Mistake 5: Forgetting CPP contributions on self-employment income. Employees split Canada Pension Plan contributions with their employer. Self-employed individuals pay both the employee and employer portions on their net self-employment income above the basic exemption. The combined rate may be subject to annual adjustment — check the current CRA rates each year.
- Mistake 6: Claiming 100 percent of a home office that is not used exclusively for business. If you work from a room that you also use personally, the CRA may challenge a full deduction. Be precise in calculating the business-use percentage and document it.
- Mistake 7: Not using the Voluntary Disclosures Program when returns are late. The CRA Voluntary Disclosures Program (VDP) may allow eligible taxpayers to come forward, file outstanding returns, and potentially reduce or eliminate penalties — though interest may still apply. VDP applications must be made before the CRA contacts you first.

Already Past the Deadline? Here Is What to Do Next
If April 30 has passed and you have not yet paid, or if June 15 has passed and you have not yet filed, do not wait any longer. Every day without action adds more interest or penalty to what you owe. File your return immediately — even without paying the full balance — because the late-filing penalty clock stops the moment your return is received by the CRA.
If you have multiple years of unfiled returns, look into the Voluntary Disclosures Program, which may reduce the penalties the CRA can assess. The single most effective thing you can do right now is talk to a tax professional who knows how the CRA processes these situations.
