💼 Key Tax Tips for Self-Employed Canadians
As a self-employed Canadian, you can deduct legitimate business expenses to lower your tax bill. The most powerful deduction is your home office — you can claim a portion of rent, utilities, and internet based on the percentage of your home used for work.
• Keep all receipts — The CRA can audit up to 7 years back. Digital records are fine.
• Track mileage — Vehicle expenses are a major deduction for freelancers who travel to clients
• CPP is deductible (partly) — You can deduct half of your CPP contributions as a business expense
• Register for GST/HST — If you earn over $30K, register to charge tax and claim input credits
• Set aside money for taxes — Put 25-30% of each payment aside for tax time

Frequently Asked Questions
Answers to common questions about self-employment taxes in Canada
Self-employed individuals report business income on their T1 personal tax return using form T2125. You pay federal and provincial income tax on net business income using the same progressive tax brackets as employees. The key difference is CPP: self-employed people pay both portions (11.9% total instead of 5.95%). You can deduct half of your CPP contributions as a business expense. Filing deadline for self-employed is June 15 (but any balance owing is still due April 30).
Common deductions include: home office expenses (percentage of rent, utilities, internet), vehicle expenses (gas, insurance, maintenance for business km), equipment and supplies, professional fees, advertising, website and software costs, meals and entertainment (50%), business insurance, capital cost allowance (depreciation), and interest on business loans. The key rule: expenses must be reasonable and incurred to earn business income.
Employees pay 5.95% of salary (matched by employer). Self-employed individuals pay 11.9% total (both portions) on net business income above $3,500, up to the maximum pensionable earnings of approximately $73,200 for 2025. The maximum combined CPP for self-employed is about $8,218. However, you can deduct half of your CPP contributions as a business expense on line 22215 of your tax return, reducing your income tax.
You must register for GST/HST once your gross revenue exceeds $30,000 in any four consecutive calendar quarters (or a single quarter). Once registered, charge GST/HST on invoices and remit to CRA. You can claim input tax credits (ITCs) to recover GST/HST paid on expenses. If under $30,000, voluntary registration can be beneficial if you have significant business expenses with embedded GST/HST.
CRA requires quarterly instalments if your net tax owing exceeds $3,000 in the current year and either of the two previous years. Due dates: March 15, June 15, September 15, December 15. Payments can be made online via CRA My Payment, your bank's bill payment, or pre-authorized debit. Missing instalments results in interest charges at CRA's prescribed rate (currently 8%).
You can claim home office expenses if the workspace is where you do most of your work (over 50% of time) or used exclusively to meet clients. Two methods: Simplified ($5 per day, max $300/year per person) or Detailed (calculate % of home used for business × actual costs like rent, utilities, insurance, maintenance). Homeowners can also claim property tax and mortgage interest percentages.
Yes, but you must track business vs personal kilometers. Deductible expenses include: gas, oil, insurance, maintenance, repairs, lease payments (limited), and capital cost allowance if you own the vehicle. Calculate the business use percentage (business km ÷ total km) and apply it to total vehicle costs. A mileage log is strongly recommended for CRA audit purposes. The detailed method is more accurate than using the simplified per-km rate.
The CRA requires you to keep books and records for at least 6 years from the end of the last tax year they relate to. Keep: all receipts and invoices (digital copies are acceptable), bank statements, credit card statements, mileage logs, contracts, and any correspondence with CRA. Using accounting software like QuickBooks, Wave, or FreshBooks makes record-keeping much easier and is itself a deductible expense.
Self-Employed Tax in Canada: What You Need to Know
Being self-employed in Canada comes with significant tax advantages but also important responsibilities. Unlike employees who have taxes deducted automatically from each paycheck, self-employed individuals must calculate, report, and remit their own taxes throughout the year. Understanding how income tax and CPP work for freelancers is essential to avoiding surprises at tax time.
How Self-Employment Income Is Taxed
Your net business income (gross revenue minus allowable expenses) is added to any other income you earned during the year and taxed at your marginal rate. The same federal and provincial progressive tax brackets apply — no special "self-employment tax" like in the United States. The main difference is CPP, where self-employed individuals pay double the rate since they cover both the employee and employer portions.
