Being self-employed in Canada — whether as a freelancer, contractor, or sole proprietor — means you're responsible for calculating and remitting your own tax, and you pay both sides of CPP. Here's exactly how it works for the 2026 tax year.
Reporting Business Income: Form T2125
Self-employed income is reported on the T2125 — Statement of Business or Professional Activities, filed alongside your personal T1 return. You report your gross income, deduct eligible business expenses, and the net amount is added to your other income and taxed at your personal marginal rate.
✅ Tip: Common deductible expenses include home office costs, vehicle use, phone/internet, professional fees, advertising, and supplies. See our full deductions guide for the complete list.
Filing Deadlines for 2026
- Filing deadline: June 15, 2027 (self-employed individuals and their spouses get an extended filing date)
- Payment deadline: April 30, 2027 — any balance owing still accrues interest from this date even though you have until June 15 to file
⚠️ Important: The extended June 15 deadline is only for filing. If you owe money, interest starts accumulating on May 1 regardless. Many self-employed Canadians miss this distinction and get an unexpected interest charge.
CPP Contributions for the Self-Employed (2026 Rates)
Employees split CPP with their employer. Self-employed individuals pay both halves — the full employee and employer portion — on their net business income.
| Employee | Self-Employed | |
|---|---|---|
| CPP1 rate (up to YMPE $74,600) | 5.95% | 11.9% |
| CPP1 maximum | $4,230.45 | $8,460.90 |
| CPP2 rate (YMPE to YAMPE $85,000) | 4% | 8% |
| CPP2 maximum | $416 | $832 |
| Combined maximum CPP | $4,646.45 | $9,292.90 |
CPP is calculated on net self-employment income above the $3,500 basic exemption. The good news: you can deduct the "employer half" of your CPP contribution directly against income, and claim a non-refundable tax credit for the other half.
Instalment Payments
If your net tax owing is more than $3,000 in the current year and in either of the two previous years, the CRA requires you to pay tax by quarterly instalments rather than one lump sum at filing time. Instalment due dates fall on the 15th of March, June, September, and December.
✅ Tip: If your income fluctuates year to year, use the CRA's "prior-year" or "current-year" instalment option — whichever results in a lower amount — to avoid overpaying or triggering instalment interest.
GST/HST Registration
You must register for GST/HST once your revenue exceeds $30,000 in a single calendar quarter or over four consecutive quarters. Below that, registration is optional. See our GST/HST registration guide for the full $30,000 rule and the Quick Method.
