If you earn income as a freelancer, contractor, consultant, Uber or taxi driver, online seller, or side hustler in Canada, your tax responsibilities are different from those of employees. There are no automatic payroll deductions, no employer contributions, and no year-end T4 to summarize everything for you. Instead, you are responsible for tracking your income, recording your expenses, and reporting your net business income properly.
This 2026 guide gives you a clear, Canada-first overview of how self-employment taxes work - without complicated accounting language.
You'll learn:
- How Form T2125 (Statement of Business or Professional Activities) works
- What business expenses you can claim (and how they reduce your taxes)
- How GST/HST and QST registration affects you
- How to calculate your net business income
- How CPP or QPP contributions apply to self-employed earnings
- What records you must keep to stay compliant with CRA rules
Unlike employees, self-employed individuals pay income tax and CPP/QPP contributions based on net profit, not gross revenue. That means proper expense tracking is critical - it directly affects how much tax you owe.
Sales tax adds another layer. If your business exceeds the small supplier threshold or operates in specific provinces, you may need to register for and manage GST/HST or QST. This includes tracking tax collected from clients and tax paid on business expenses.
The good news? Once you understand the structure, self-employed taxes follow a logical system:
- Track all income
- Track allowable business expenses
- Calculate net income
- Report it on T2125
- Pay income tax and pension contributions
- Remit any required sales tax
This guide is designed to help you understand the big picture before tax season, so you can stay organized all year and avoid last-minute stress.
The information provided here is general educational material for 2026 and does not replace professional tax advice. If your situation involves incorporation, employees, multiple income streams, or large capital purchases, consider consulting a qualified tax professional.
Let's break everything down step by step.

T2125 explained
The T2125 (Statement of Business or Professional Activities) is commonly used to summarize your self-employed income and expenses on your Canadian tax return. It helps show your gross income, deductible expenses, and net income for the year.
What you need before you start
- Income records and invoices
- Receipts for business expenses
- Mileage or vehicle logs (if applicable)
- Bank or credit card statements
Important
Keep receipts and separate business and personal spending as much as possible. Clean records make your T2125 summary more accurate and easier to review.
CRA notes on T2125 expenses (high level)
- Claim reasonable current expenses to earn business income, and include only the business-use portion.
- Capital property is not claimed as a current expense on T2125.
- If you claim GST/HST input tax credits, reduce the expense by the ITC amount and record the net figure.
- Common categories include advertising, meals, insurance, interest/bank charges, office expenses, professional fees, rent, repairs, travel, utilities, and motor vehicle costs.
- Examples of non-claimable items include personal expenses, drawings to self/partners, and most fines or penalties.

Key dates (simple)

Income & expenses overview
Gross income is the total you earned before expenses. Net income is what remains after eligible expenses are deducted. Most self-employed reporting focuses on net income.
Current expenses are day-to-day costs (like software or supplies). Capital expenses are longer-term assets (like equipment) that may be handled differently. Keep it simple and track what you spent and why.
| Common expense | Example |
|---|---|
| Home office | Workspace portion of rent or utilities |
| Vehicle | Business-use portion of fuel or maintenance |
| Software | Accounting, invoicing, or design tools |
| Marketing | Ads, website hosting, or printing |
Common expense categories (examples)
- Advertising and marketing (ads, flyers, website design).
- Vehicle expenses for business use (fuel, maintenance, insurance, parking, lease payments).
- Banking and financing costs (business account service charges, loan interest, brokerage fees).
- Office supplies and business software (pens, paper, tools used for work).
- Phone and utilities for business use (mobile plan, internet, portion of home utilities).
- Professional fees and dues (accounting, legal, memberships, industry subscriptions).
- Travel related costs (transportation, lodging, and meals where permitted).
Track the business-use portion and keep records to support your claims.
Expense checklist
Use these starter lists and track the business-use portion.
Vehicle & travel
- Mileage log (business-use portion)
- Fuel and maintenance receipts
- Parking and tolls for business trips
Home office basics
- Workspace measurements or rent portion
- Internet and phone (business-use portion)
- Office supplies and small equipment
Tools & subscriptions
- Accounting or invoicing software
- Industry tools and subscriptions
- Cloud storage or collaboration apps
GST/HST basics
GST/HST is a sales tax collected on certain goods and services in Canada. Self-employed people may need to register and collect GST/HST depending on their revenue and activities.
The small supplier threshold concept is important. If you cross the threshold, registration can become required. Rules can vary, so always confirm with CRA guidance.
Registration checklist
- Review recent revenue totals
- Confirm whether you cross the small supplier threshold
- Decide if voluntary registration makes sense
- Set up a system to track GST/HST collected

Quick Method vs Regular Method
Regular method
Track GST/HST collected, subtract ITCs for eligible expenses, and remit the difference.
Quick method
Use a simplified remittance calculation based on eligible sales. It can reduce paperwork, but is not always better.
Which one is better? It depends on your expenses and ITCs. Consider professional advice before choosing.
Quebec QST + GST registration basics
In Quebec, businesses may need to register for both GST and QST. If your activities are in Quebec, track QST separately and follow Revenu Quebec guidance for registration and filing.
The $30,000 threshold concept can apply to GST and QST. If you cross the threshold, you may need to register for both.
Quebec checklist
- Confirm if your sales are in Quebec
- Check GST and QST registration requirements
- Track GST and QST separately in your system
- Review Revenu Quebec filing guidance
Common pitfalls
- Mixing GST and QST totals in one bucket
- Missing combined return steps
- Not keeping Quebec-specific records
