Self-Employed Tax Canada: CPP, T2125 and Instalments (2026)

Quick answer: Self-employed tax in Canada means reporting business income on Form T2125 with your T1 return, paying federal and provincial income tax on the net profit, and paying both halves of CPP. For 2026 that is 11.9% on net earnings between $3,500 and $74,600, plus 8% CPP2 up to $85,000. Returns are due June 15 and balances April 30.

When you work for yourself in Canada, nobody withholds tax from your income. That freedom comes with three jobs: tracking your profit, paying the Canada Pension Plan (CPP) contributions an employer would normally share, and paying tax on time, often through quarterly instalments. This guide explains how self employed tax in Canada works for sole proprietors and freelancers, using the 2026 CPP figures published by the government, with a full worked example.

This is general information, not tax advice. Quebec residents contribute to the QPP instead of CPP and file a separate provincial return; confirm details with the CRA, Revenu Québec or an accountant.

What counts as self-employment income in Canada?

You are self-employed when you carry on a business as a sole proprietor or as a partner in a partnership, rather than working as an employee. Freelancers, independent contractors, consultants, tradespeople, gig workers and online sellers usually fall into this category. The CRA looks at the working relationship, such as control over your work, ownership of tools, chance of profit and risk of loss, and integration into the payer's business, rather than the label in a contract.

If you incorporate, the corporation is a separate taxpayer that files a T2 return, and you are paid through salary or dividends. This article focuses on unincorporated sole proprietors, the most common setup for freelancers.

How is self-employed tax calculated in Canada?

Your bill has two main parts:

1. Income tax. Net business income (gross income minus allowable expenses) is added to any other income and taxed at the regular progressive federal and provincial rates. There is no separate self-employment income tax rate.
2. CPP contributions. Because you are both employer and employee, you pay both halves of CPP on your net self-employment earnings, calculated on Schedule 8 of your return.

If you are registered for GST/HST, the tax you collect from customers is not your income. It is remitted separately on your GST/HST return. See our guide on how to register for GST/HST to check whether you need to.

How much CPP do self-employed people pay in 2026?

CPP now has three layers: the base contribution, the first additional (enhancement) contribution, and the second additional contribution (CPP2) on a higher band of earnings. The figures below are the 2026 rates and maximums published on canada.ca.

2026 CPP figure	Employee (and employer, each)	Self-employed
Basic exemption	$3,500	$3,500
Year's maximum pensionable earnings (YMPE)	$74,600	$74,600
Base plus first additional rate (on $3,500 to $74,600)	5.95%	11.9%
Maximum base plus first additional contribution	$4,230.45	$8,460.90
Year's additional maximum pensionable earnings (YAMPE)	$85,000	$85,000
CPP2 rate (on $74,600 to $85,000)	4%	8%
Maximum CPP2 contribution	$416	$832

So the most a self-employed person can pay in CPP for 2026 is $8,460.90 plus $832, or $9,292.90. If you also have employment income, the CPP deducted by your employer counts toward the same maximums, and Schedule 8 works out what is still owed on your business earnings.

How the CPP deduction and credit work

You do not lose the whole contribution to tax. The employer-equivalent half of the base contribution, and all of the enhanced contributions (the first additional portion and CPP2), are deducted from your income. The employee-equivalent base portion is claimed as a non-refundable tax credit. In practice this lowers the real cost of CPP by your marginal tax rate on the deductible part.

How to report self-employment income on Form T2125

Form T2125, Statement of Business or Professional Activities, is where you report your gross income and expenses. You file one T2125 for each business. Here is the process:

1. Identify the business. Enter your business name, address, fiscal period (usually January 1 to December 31 for sole proprietors) and the industry code that best matches your main activity.
2. Report gross income. Total your invoiced sales and fees for the year, excluding GST/HST you collected (if you are a registrant using the regular method). Your invoices and bank deposits are the source. An organized invoice log makes this step quick.
3. Enter business expenses. Claim reasonable costs incurred to earn income: advertising, software subscriptions, office supplies, professional fees, phone and internet (business portion), insurance, travel, meals (generally 50%), and supplies.
4. Claim capital cost allowance (CCA). Computers, furniture and vehicles are not expensed in full. You claim CCA by asset class each year.
5. Add business-use-of-home and vehicle expenses. Home office costs are prorated by area and limited so they cannot create or increase a business loss. Vehicle costs are prorated by business kilometres from a logbook.
6. Carry net income to your T1. Net business income flows to your return and to Schedule 8 for CPP.

Common deductible expenses for Canadian freelancers

Expense	How it is claimed
Software, hosting, subscriptions	Fully deductible if used for the business
Laptop, camera, furniture	Capital cost allowance by class
Home office	Business-use percentage of rent or mortgage interest, utilities, insurance, property tax; cannot create a loss
Vehicle	Business kilometres divided by total kilometres, applied to fuel, insurance, repairs, lease or CCA
Meals and entertainment	Generally 50% of the cost
Accounting and legal fees	Fully deductible
Bank and payment processing fees	Fully deductible

When are self-employed taxes due in Canada?

Self-employed individuals and their spouses or common-law partners get an extended filing deadline, but not an extended payment deadline.

Item	Deadline
T1 return with T2125 (2026 tax year)	June 15, 2027
Balance owing for 2026 (income tax and CPP)	April 30, 2027
Quarterly instalments (if required)	March 15, June 15, September 15, December 15
Annual GST/HST return (individual, December year end)	June 15, with payment due April 30

When a deadline falls on a weekend or public holiday, the CRA treats a return or payment as on time if it is received on the next business day. Interest runs on any balance not paid by April 30, even if you file on time in June.

Do self-employed people have to pay tax instalments?

You must pay instalments if your net tax owing is more than $3,000 in the current year and in either of the two previous years ($1,800 for Quebec residents, since the threshold is based on federal tax only). Net tax owing includes income tax and CPP contributions on self-employment income, minus tax already withheld at source.

The CRA offers three ways to calculate instalments. You can follow the reminder amounts it mails you (the no-calculation option, based on prior years), pay a quarter of last year's net tax owing (prior-year option), or estimate this year's tax and pay a quarter of it (current-year option). The reminder option is the safest from an interest point of view, because the CRA will not charge instalment interest if you pay those amounts on time, even if you end up owing more. The CRA's instalment guidance explains each option.

Worked example: self-employed tax for a Canadian freelancer

Liam is a self-employed web developer in Ontario with no other income. In 2026 he invoices $92,000 (excluding HST) and has $14,500 of deductible expenses, including software, a home office share, a laptop CCA claim and accounting fees.

Step	Calculation	Amount
Gross business income	From invoices	$92,000.00
Expenses	From T2125	-$14,500.00
Net self-employment income	$92,000 - $14,500	$77,500.00
CPP base and first additional	($74,600 - $3,500) x 11.9% (capped)	$8,460.90
CPP2	($77,500 - $74,600) x 8%	$232.00
Total CPP	$8,460.90 + $232.00	$8,692.90

Part of that $8,692.90 is deducted from Liam's income and the rest generates a tax credit. His federal and Ontario income tax is then worked out on the remaining taxable income using the 2026 brackets in his tax software. Because his net tax owing will be well above $3,000, Liam should expect instalment reminders from the CRA from the following year onward, and he should be setting aside money from every invoice. A common rule of thumb is to reserve 25% to 35% of net income for income tax and CPP combined, but your own rate depends on your province and deductions (see how much to set aside for taxes).

How to track self-employed income and expenses during the year

The easiest tax season is one where the numbers already exist. Self-employed Canadians who do well at tax time usually follow a simple monthly routine rather than rebuilding the year from bank statements in April.

• Invoice every job. Even for small or cash jobs, issue a numbered invoice. It records the date, client and amount, and it separates GST/HST from your fee. Our guide on how to invoice as a sole proprietor covers the fields to include.
• Watch unpaid invoices. Business income is generally reported when it is earned, not when the client pays. An accounts receivable aging report shows which invoices are still open at year end, and which may need a reserve or bad debt claim.
• Log expenses as they happen. Photograph receipts, label them by T2125 category and record business kilometres weekly. An expense report template works well even for a one-person business.
• Reconcile monthly. Match invoices and expenses to bank deposits and payments so nothing is missed or counted twice.
• Review quarterly. Compare your profit so far with your tax savings and your instalment schedule. If income has jumped, increase your savings rate before the next instalment date.

A spreadsheet is enough for many freelancers at the start. As volume grows, accounting software that imports bank transactions can save hours, but the invoice remains the source document for every dollar of income on your T2125.

Common mistakes self-employed Canadians make

• Forgetting CPP when budgeting. Many new freelancers save for income tax but are surprised by a CPP bill of several thousand dollars.
• Thinking June 15 is the payment date. Payment is due April 30. Interest starts on May 1.
• Including GST/HST in income. Tax collected for the government is not revenue on your T2125 under the regular method.
• Expensing capital assets. Computers and vehicles go through CCA, not straight expenses.
• Weak records. No mileage log, no home office measurements and missing receipts make claims hard to defend.
• Ignoring the $30,000 GST/HST threshold. Income tax and GST/HST are separate systems, and passing the threshold creates a new obligation.
• Mixing personal and business accounts. A separate account makes bookkeeping, instalments and reviews far easier.

Self-employed tax checklist for Canada

• Issue numbered invoices for every sale and keep a running income log. Our bookkeeping basics guide shows a simple system.
• Save receipts and keep a vehicle logbook and home office measurements.
• Track taxable sales against the $30,000 GST/HST threshold.
• Move a fixed percentage of each payment into a tax savings account.
• Pay instalments on March 15, June 15, September 15 and December 15 if required.
• Pay your balance by April 30 and file your T1 with T2125 by June 15.
• Review deductions with a self-employed deductions checklist (written for the US, but most expense categories are similar) and confirm Canadian rules with an accountant.
