How to Use This Canada Self-Employed Tax Calculator
Enter your net self-employment income β your gross business revenue minus deductible business expenses. Select your province for accurate combined federal + provincial tax. If you also received T4 employment income, enter it separately as it affects your CPP ceiling.
This calculator uses 2025 federal rates and provides estimates for major provinces. Quebec residents should note that Quebec operates its own pension plan (QPP) and has different provincial rates.
The Formula
CPP = CPP Earnings Γ 11.9% (both employee + employer portions)
CPP Deduction = CPP Γ 100% (fully deductible from net income)
Taxable Income = Net SE Income β CPP Deduction
Federal Tax = Apply federal brackets β Basic Personal Amount credit ($16,129 Γ 15%)
Provincial Tax = Apply provincial brackets β Provincial personal amount credit
Take-Home = Net SE Income β CPP β Federal Tax β Provincial Tax
Example
CPP earnings: $75,000 β $3,500 = $71,500, capped at $71,300
CPP (11.9%): $71,300 Γ 11.9% Γ (67,800/71,300) = ~$8,068 (max)
Taxable income: ~$75,000 β $8,068 = $66,932
Federal tax (approx): ~$10,200
Ontario provincial tax (approx): ~$4,200
Total tax: ~$22,468
Take-home: ~C$52,532
