How to Report Self-Employment Income in Canada

In Canada, you report self employment income on your personal T1 income tax return using Form T2125, Statement of Business or Professional Activities. That form is filed together with your T1, not on its own, and the net business income it calculates flows into your return, where it is taxed at your marginal rate. Because you are a sole proprietor, your business income is your personal income — there is no separate corporate return and no T4 slip for your own earnings.

Who needs to report self-employment income

You generally need to report self-employment income if you carried on a business, practised a profession, earned commission income, or worked as an independent contractor during the tax year — even if the work was part-time, occasional, or a side gig alongside a job. CRA treats these activities as business or professional income when you are not an employee.

If you receive a T4A for fees for services or commissions, those amounts still belong on your T1 as self-employment income rather than as employment income. Report the income in the year you earned it, whether or not a client has paid you yet. Cash-basis businesses record income when it is received; accrual-basis businesses record it when it is earned. Confirm which method fits your situation before you file.

Where self-employment income goes on your tax return

Self-employment income does not go on a T4. As a sole proprietor, you report it through the business sections of your T1 return.

Steps to report self-employment income

1. Total your gross business income for the year from all sources.
2. Total your eligible business expenses — only amounts incurred to earn that income.
3. Complete Form T2125 explained for each business or professional activity; you may need more than one copy.
4. Transfer the net income or loss to the business or professional income lines on your T1.
5. Include amounts that depend on net business income, such as CPP contributions and any instalments you already paid.
6. File your return and keep the records that support every figure.

If this is your first year, the broader filing walkthrough in how to file taxes as a sole proprietor covers the sequence in more detail.

Self-employed income tax: what you owe beyond income tax

Net self-employment income raises your taxable income, so you pay tax at your marginal rate — the rate that applies to your highest dollar of income. No employer withholds tax for you, so setting money aside through the year matters. Two further amounts typically apply:

• CPP: As a self-employed person you generally pay both the employee and employer portions of Canada Pension Plan contributions on net self-employment income above the basic exemption, up to the yearly maximum. See CPP for self-employed Canadians.
• EI: EI is generally not required for self-employed people, although you may be able to opt into EI special benefits.
• GST/HST: If you are registered or required to register, GST/HST is collected on behalf of the government and reported separately — it is never part of your revenue.

, confirm the current CPP rate, basic exemption and maximum on the CRA website rather than relying on older figures.

Records, deadlines and instalments

Keep documents that support every line on the T2125: sales invoices, receipts, bank and credit card statements, contracts and mileage logs. CRA generally expects records to be kept for six years from the end of the tax year, but confirm the current requirement.

The filing deadline for self-employed individuals, and for their spouse or common-law partner, is generally later than the standard deadline. The balance owing, however, is usually still due on the standard date, so estimate your tax early. If you owe a significant amount, CRA may ask you to pay quarterly instalments — see tax instalments in Canada.

Common reporting mistakes to avoid

Three mistakes come up repeatedly. First, reporting only amounts that appear on a slip and overlooking cash, e-transfer or platform income. Second, deducting personal expenses as business costs — see sole proprietorship tax deductions for what qualifies. Third, mixing personal and business banking so that records become impossible to reconcile. A clean, separate bank account and a simple bookkeeping routine through the year make the T2125 far easier to complete.

Getting help and confirming current rules

You can file on paper or through certified tax software, view your account history in CRA My Business Account, and consult CRA's business and professional income guide for line-by-line instructions. An accountant can help if you have inventory, multiple activities, or losses.
