Warnings and insights
Side hustle taxes in Canada
Revenue vs profit
Revenue is what you collect. Profit (net business income) is revenue minus eligible business expenses. Tax is usually based on net income, not gross revenue.
Common deductible business expenses
Depending on your situation, common expenses can include supplies, software, a business-use share of phone/internet, mileage, and professional services.
Why setting money aside matters
Many side hustlers are not taxed at source. Setting aside money regularly helps avoid tax-time cash-flow stress.
CPP/QPP basics for self-employment income
Self-employed people may need to cover both portions of CPP/QPP contributions on net self-employment income, subject to rules and thresholds.
GST/HST small supplier reminder
If taxable revenue approaches or exceeds the small supplier threshold, registration obligations may apply.
When to talk to an accountant
Consider professional support if your income is growing, you have mixed income sources, or you are unsure about deductions, sales tax, and installments.
