The Ultimate Guide to Filing Taxes for Self-Employed Canadians

Why Self-Employed Taxes in Canada Feel Overwhelming

If you’re a freelancer, contractor, or small business owner, you’ve likely asked: “How do I file my self-employed taxes in Canada without missing deductions or facing CRA penalties?”

Unlike employees, self-employed Canadians must track income, pay CPP contributions, and claim business deductions through the T2125 form. The process can feel daunting, but with the right strategy, you can file your taxes, maximize deductions, and keep more of your hard-earned money.

At Taxease, we’ve helped thousands of Canadians file confidently with tools like our TaxEase Self-Employed Tax Software—tailored for freelancers, gig workers, and sole proprietors.

Step 1 – Understanding How CRA Taxes the Self-Employed

Unlike salaried employees, self-employed workers in Canada file taxes using:

• T1 General Return (personal tax return)

• T2125 Statement of Business or Professional Activities (to report business income/expenses)

👉 This means you pay income tax + CPP contributions on your net business income.

Self-Employed CPP Contributions

As a sole proprietor, you pay both the employer and employee portions of CPP, totaling 11.9% (2024 rates) on income up to $68,500.

👉 Pro Tip: Always set aside 25–30% of your income for taxes and CPP so you don’t get caught short at tax time.

Step 2 – Filing T2125 Canada (Business Income & Expenses)

The T2125 form is where you declare your gross business income and claim expenses to reduce taxable income.

Common Categories on T2125

• Gross business/professional income

• Advertising and promotion

• Office supplies and software

• Meals and entertainment (50% deductible)

• Travel and vehicle expenses

• Professional fees (legal, accounting, software like TaxEase)

👉 Example: If you earned $60,000 freelancing but had $15,000 in deductible expenses, you’ll only be taxed on $45,000.

Step 3 – The Self-Employed Tax Deductions You Can’t Afford to Miss

Claiming the right deductions is the key to lowering your tax bill. Here’s the Canadian business tax deductions list many freelancers overlook:

Highest-Value Deductions for Self-Employed Canadians

• Home Office Deduction Canada: Claim a portion of rent, mortgage interest, utilities, and internet.

• Vehicle Expenses: Gas, insurance, repairs—must keep a mileage log.

• Phone & Internet: Business-use percentage.

• Capital Cost Allowance (CCA): Depreciation on laptops, furniture, equipment.

• Professional Development: Courses, certifications (even CRA’s Canada Training Credit).

Step 4 – GST/HST Rules for the Self-Employed

If you earn over $30,000 in a 12-month period, you must register for a GST/HST number.

• You charge GST/HST on invoices.

• You remit it to CRA quarterly or annually.

• You can claim Input Tax Credits (ITCs) on business purchases.

👉 Many new self-employed Canadians miss registering on time, which can lead to CRA penalties.

Step 5 – Deadlines & Avoiding CRA Penalties

Self-employed Canadians get an extended tax filing deadline:

• Filing Deadline: June 15, 2025 (extended to June 16 since the 15th is Sunday).

• Payment Deadline: April 30, 2025.

👉 Even if you file in June, taxes owed must still be paid by April 30 to avoid interest.

Common CRA Penalties Self-Employed Canadians Face

• Late Filing Penalty: 5% of balance owing + 1% per month.

• GST/HST Late Remittance Penalties.

• Over-contributions or false claims on deductions.
