How to File Taxes as a Freelancer in Canada: Step-by-Step Guide (2026)

Step 1: Calculate Your Gross Business Income

Add up all income earned from freelance/self-employment activities in 2025. This includes:

• Client payments (even if no T4A was issued)
• Platform income (Upwork, Fiverr, Shopify, etc.)
• Cash payments
• Barter income (fair market value of goods/services received)

CRA expects you to report all income — not just amounts on tax slips. If a client paid you $400, it's taxable even if they didn't issue a T4A (the $500 threshold is for the payer's reporting, not your obligation).

Step 2: Organize and Categorize Your Business Expenses

Group your expenses into CRA T2125 categories:

Step 3: Fill Out Form T2125

Form T2125 is the heart of your freelance tax return. Most tax software walks you through it, but here's what each section covers:

• Part 1: Business identification — your name, business name (if any), industry code, fiscal year
• Part 2: Internet business activities (if applicable)
• Part 3: Gross income
• Part 4: Business expenses (the table above)
• Part 5: Net income calculation
• Part 6: Business-use-of-home expenses
• Part 7: Motor vehicle expenses

Your industry code matters — CRA uses it to benchmark your deductions against similar businesses. Find yours at CRA Industry Codes.

Step 4: Calculate Your CPP Contributions

As a freelancer, you pay both the employer and employee portions of CPP. For 2025 (filed in 2026):

Your tax software calculates this on Schedule 8 automatically based on your T2125 net income. Half of your CPP contribution is deductible on line 22200.

Step 5: Claim All Eligible Deductions & Credits

Beyond T2125 expenses, don't forget:

• RRSP contributions — reduces taxable income dollar-for-dollar (RRSP guide)
• Home office expenses — rent, utilities, property tax proportional to workspace (home office guide)
• Vehicle expenses — gas, insurance, maintenance for business driving (vehicle expenses guide)
• Health & dental premiums — deductible as medical expenses
• Professional development — courses, conferences, certifications
• Half of CPP — deducted on line 22200

Step 6: File Your HST/GST Return (If Registered)

If you're registered for HST/GST, you must file a separate HST return — it's not part of your income tax return.

• HST collected from clients minus Input Tax Credits (ITCs) on business purchases = amount you owe (or get refunded)
• Quick Method: If you opted in, you remit a flat percentage of revenue (varies by province) and keep the difference
• Filing frequency: Annual, quarterly, or monthly depending on your revenue

Step 7: Choose Your Tax Software & NetFile

CRA-certified software that handles T2125 well:

• Wealthsimple Tax (free) — excellent for most freelancers
• TurboTax Self-Employed ($40–60) — more hand-holding, good for complex situations
• StudioTax (free/pay-what-you-want) — desktop-based, bare-bones but solid
• UFile ($20–40) — good balance of features and price

All of these support NetFile — CRA's electronic filing system. You'll get your Notice of Assessment in about 2 weeks (vs. 8+ weeks for paper).

Step 8: Pay What You Owe (By April 30!)

Even though your filing deadline is June 15 as self-employed, your payment deadline is still April 30. Interest starts accruing May 1 on any unpaid balance.

Payment options:

• CRA My Payment — online via Interac Debit
• Online banking — add CRA as a payee
• Pre-authorized debit — set up a payment plan
• At your bank — with a remittance voucher

Can't pay the full amount? File on time anyway — the late-filing penalty (5% + 1%/month) is separate from interest on unpaid amounts. Filing late when you owe is the worst option.
