> Self-employed taxes in Canada are paid on business profit, not on gross sales: you report income and expenses on Form T2125, pay income tax at the normal federal and provincial rates, and pay both halves of CPP (11.9% in 2026). The 2026 return is due June 15, 2027, but any balance owing is due April 30, 2027.

## How are self-employed people taxed in Canada?

Self-employed taxes in Canada come down to one number: your net business income, which is gross income minus deductible business expenses. That profit is added to any other income on your T1 return and taxed at the same federal and provincial rates that apply to wages. On top of income tax, you pay Canada Pension Plan (CPP) contributions on the profit, and in some cases you owe GST/HST on your sales.

**Self-employed** means you carry on a business yourself, as a sole proprietor or a partner, rather than working as an employee. Nobody withholds tax from your pay, so the whole amount for the year lands on your return unless you pay ahead through instalments.

The rest of this guide walks through each stage in that chain and links to a detailed page for each one. If you are filing for the first time as a freelancer, read the sections in order.

## Who counts as self-employed for tax purposes?

You are self-employed if you run a business on your own account: you decide how the work is done, supply your own tools, can make a profit or take a loss, and can usually take work from several clients. Freelancers, consultants, trades contractors, commission salespeople who are not employees, and ride-share or delivery drivers all usually fall in this group.

- **Sole proprietor:** you and the business are the same taxpayer. Profit is reported on your personal T1 return.
- **Partner in a partnership:** your share of partnership profit is reported on your own T1, also on Form T2125.
- **Incorporated owner:** the corporation files its own T2 return. You report only the salary or dividends it pays you, so most of this cluster does not apply.
- **Contractor paid on a T4A:** a client may issue a T4A slip showing fees for services. The slip is information only; you still report the full income on Form T2125. See [what a T4A slip reports](https://canadataxdesk.com/tax-slips/t4a-slip-canada).

> **Side income counts too:** There is no minimum amount before business income becomes taxable. A weekend photography business that nets $2,000 is reported the same way as a full-time practice.

## Reporting self-employment income on Form T2125

Every sole proprietor reports business or professional income on Form T2125, Statement of Business or Professional Activities, and files it with the T1 return. You fill in a separate T2125 for each business you operate. The form collects your gross sales, subtracts your expenses and capital cost allowance, and produces the net income that flows to line 13500 (business), 13700 (professional) or 13900 (commission) of the return.

Tax software and certified NETFILE products include the T2125, so you do not need the paper version to file online. The walk-through in [how to fill in the T2125 form](https://canadataxdesk.com/self-employed/t2125-form-self-employed) covers each part, including the industry code, GST/HST in gross sales and the business-use-of-home calculation.

## What self-employed tax deductions can you claim in Canada?

You can deduct any reasonable expense you incur to earn business income, as long as it is not personal or capital in nature. Common claims include advertising, supplies, professional fees, rent, business insurance, phone and internet business use, vehicle costs and a share of home costs when the home is your principal place of business.

Two limits catch many first-year filers. Meals and entertainment are deductible at only 50% of the cost, and equipment that lasts more than a year is written off over time through capital cost allowance (CCA) rather than in one shot. The full list with line numbers is in [business expenses you can deduct](https://canadataxdesk.com/self-employed/business-expenses-canada).

## Do I pay CPP on self-employment income?

Yes. Self-employed people pay both the employee and employer shares of CPP, which is why the rate looks high. For 2026 the combined rate is 11.9% on net self-employment earnings between $3,500 and $74,600, a maximum of $8,460.90, plus an 8% second additional contribution (CPP2) on earnings from $74,600 to $85,000, a maximum of $832 (CRA, T4127 payroll formulas, January 2026).

Part of what you pay comes back as tax relief. Half of the base contribution is claimed as a non-refundable credit and the rest, including all CPP2, is deducted from income. [CPP for self-employed people](https://canadataxdesk.com/self-employed/cpp-self-employed) shows the split with worked numbers. Quebec residents pay into the Quebec Pension Plan (QPP) instead, at a 2026 self-employed rate of 12.6% set by Retraite Québec.

## How much should I set aside for tax as a self-employed person?

A practical approach is to move a fixed percentage of every payment you receive into a separate savings account. For an Ontario resident with no other income, our worked estimates put income tax plus CPP at roughly 21% of net profit at $40,000, 26% at $70,000 and 28% at $100,000 for 2026. Rates differ by province, so run your own numbers in the [self-employed tax calculator](https://canadataxdesk.com/self-employed/self-employed-tax-calculator).

1. Open a separate account that you use only for tax.
2. Each time a client pays you, transfer your chosen percentage of the payment, based on expected profit.
3. If you are registered for GST/HST, also move the full GST/HST you collected, because none of it is yours.
4. Recalculate after each quarter using your actual profit to date, and adjust the percentage up or down.

## When do self-employed people file and pay?

For the 2026 tax year, a self-employed person and their spouse or common-law partner can file until Tuesday, June 15, 2027. Any balance owing is due Friday, April 30, 2027, and compound daily interest starts on unpaid amounts after that date. The CRA's prescribed rate on overdue taxes is 7% for October to December 2026; the 2027 rates are set each quarter.

| What | Date |
| --- | --- |
| Balance owing for 2026 due | Friday, April 30, 2027 |
| 2026 T1 return with T2125 due | Tuesday, June 15, 2027 |
| 2027 instalments (if required) | March 15, June 15, September 15, December 15, 2027 |
| Annual GST/HST return, calendar-year sole proprietor | File by June 15, 2027; pay by April 30, 2027 |

Key dates for 2026 self-employment income

What is known now about the 2027 filing season: the CRA has not announced when NETFILE will open for 2026 returns (it opened on February 23 in 2026), the current NETFILE service closes on January 29, 2027, and the 2027 CPP limits, tax brackets and basic personal amount are expected in November 2026. Since February 9, 2026, notices of assessment no longer arrive through tax software: they appear in your CRA account, or by mail if you have no account.

The difference between the two dates is explained in more detail on the [self-employed tax deadline](https://canadataxdesk.com/filing/self-employed-tax-deadline) page.

## Do self-employed people have to pay tax instalments?

You must pay quarterly instalments if your net tax owing is more than $3,000 ($1,800 in Quebec) in the current year and was also more than that in either of the two previous years. Net tax owing includes income tax and the CPP on your self-employment income. Most people in their first profitable year are not yet required to pay, but the second year often triggers the rule.

The CRA sends reminders in February and August showing a suggested amount. The three ways to calculate the amounts, and how instalment interest works, are covered in [CRA tax instalments](https://canadataxdesk.com/self-employed/tax-instalments-cra).

## When do you need to register for GST/HST?

You must register for GST/HST once your worldwide taxable sales pass $30,000 in a single calendar quarter or over the last four consecutive quarters, and you then have 29 days from your effective date of registration to register. Below that level you are a small supplier and registration is optional. Commercial ride-sharing drivers are the main exception: they must register from their first fare.

GST/HST you collect is not business income for your T1 once you account for it on your GST/HST return. Drivers and couriers should read [taxes for Uber and delivery drivers](https://canadataxdesk.com/self-employed/uber-driver-taxes-canada), which covers both the income tax and GST/HST sides.

## How to file self-employment taxes in Canada, step by step

1. Total your gross business income for January 1 to December 31, 2026, including tips and platform payouts.
2. Sort receipts by expense type and separate the business part of shared costs such as your phone, vehicle and home.
3. Complete Form T2125 in certified software or on paper and check the net income figure it produces.
4. Let the software complete Schedule 8 for CPP on your self-employment earnings.
5. Apply any instalments you paid in 2026 against the total; they show on your CRA account.
6. Pay the balance by April 30, 2027, then file the return by June 15, 2027 through NETFILE or on paper.
7. Keep receipts, invoices and your vehicle logbook for at least six years after the end of the tax year.

## Common questions

### What percentage of tax do self-employed pay in Canada?

There is no separate self-employment tax rate. You pay the ordinary federal rate, starting at 14% for 2026, plus your provincial rate on net profit, and 11.9% CPP on net earnings between $3,500 and $74,600. Combined, an Ontario resident typically pays about a fifth to just under a third of net profit, depending on income.

### What tax forms do self-employed people file in Canada?

The T1 return, with Form T2125 for each business and Schedule 8 for CPP; Quebec residents use the Quebec version of Schedule 8, or Form RC381 if they also have CPP contributions. Farmers use Form T2042 and fishers Form T2121 instead of the T2125. If you are registered for GST/HST, you also file GST/HST returns under your business number.

### Do I have to file a tax return if my business lost money?

Yes, you should file. A business loss on Form T2125 can reduce other income in the same year, and any unused non-capital loss can generally be carried back 3 years or forward 20 years, so reporting it protects its value.

### Is self-employment income taxed higher than a salary?

Income tax rates are the same. The difference is CPP: an employee pays 5.95% and the employer pays the other 5.95%, while a self-employed person pays the full 11.9% alone. Self-employed people can, however, deduct business expenses that employees usually cannot.

### Can I file self-employed taxes with NETFILE?

Yes. Most sole proprietors can send a T1 return with Form T2125 through NETFILE using certified software, as long as none of the NETFILE exclusions apply, such as more than 12 sets of financial statements.

### Do I need a business number to be self-employed?

Not for income tax. You report business income under your social insurance number. You need a business number only when you register for GST/HST, open a payroll account or incorporate.
