Self-Employed Tax Canada Guide 2025

Complete tax guide for Canadian freelancers and self-employed individuals — filing deadline, T2125, GST/HST, deductions, and CPP obligations.

Self-Employed Filing Deadline

If you or your spouse is self-employed, your tax return filing deadline is June 15, 2025 for the 2024 tax year. However, any balance owing is still due by April 30, 2025. Interest charges begin May 1 on any unpaid amount, even if you don't file until June.

Form T2125 — Statement of Business Income

All self-employment income is reported on Form T2125 (Statement of Business or Professional Activities). You report:

• Gross business income (all revenue received)
• All eligible business expenses
• Net income = Gross income minus eligible expenses

Net business income flows to line 13500 of your T1 general return and is combined with any employment income for total income calculation.

GST/HST Registration

You must register for a GST/HST account when your total self-employment revenue in any 12-month period exceeds $30,000. Once registered, you charge GST/HST to clients, collect it, and remit it to the CRA periodically. In return, you can claim Input Tax Credits (ITCs) to recover the GST/HST you paid on business expenses — often resulting in a net refund.

CPP Contributions for Self-Employed

Self-employed Canadians pay both the employee and employer portions of CPP — 11.9% on net self-employment income above the basic exemption of $3,500. The maximum self-employed CPP contribution for 2024 is approximately $7,735. You can deduct the employer-half (50%) as a business expense on your T2125, which reduces your taxable income.

Immediate Expensing for Small Business

Canadian-controlled private corporations (CCPCs) and self-employed individuals can immediately deduct up to $1.5 million in eligible depreciable property acquired after January 1, 2022. This allows you to write off equipment, computers, and other capital assets in the year of purchase rather than depreciating them over many years via CCA.

Quarterly Tax Instalments

If you owe more than $3,000 in tax for the current year and either of the two prior years, the CRA requires quarterly instalment payments in March, June, September, and December. Failing to pay instalments results in instalment interest even if your full balance is paid by April 30.

RRSP Strategy for Self-Employed

Unlike employees, self-employed Canadians have no workplace pension. RRSP contributions are especially valuable — they reduce taxable income at your marginal rate and allow tax-deferred growth. Maximize your RRSP room every year, and consider also using a First Home Savings Account (FHSA) if eligible.
