Tax Considerations
Key Tax Differences Between Employees and the Self-Employed
In Canada, one of the most significant differences between being an employee and being self-employed lies in tax obligations and available deductions. Employees have income tax, CPP contributions, and (where applicable) EI premiums automatically deducted from their paycheques by their employer. In contrast, self-employed individuals must calculate and remit their own taxes — typically through instalments or at tax time — and are responsible for both the employee and employer portions of CPP (but not EI unless they opt into the EI Special Program for self-employed).
Additionally, self-employed sole proprietors can deduct legitimate business expenses (e.g., home office, vehicle, supplies) from their gross revenue to arrive at net business income, potentially reducing taxable income and overall tax liability. However, these deductions must be clearly documented and directly tied to earning business income to satisfy CRA requirements.
Understanding CPP Contributions for the Self-Employed
CPP contributions are a major financial consideration when comparing employment statuses. As an employee, you pay 5.95% of your pensionable earnings (up to the Year's Maximum Pensionable Earnings of $68,500 in 2025), and your employer matches that contribution. As a self-employed individual, you must pay both the employee and employer portions — totaling 11.9% — on net business income between $3,500 and $68,500 in 2025.
While this may appear disadvantageous, it’s important to note that self-employed contributors still qualify for the same CPP retirement, disability, and survivor benefits as employees. Moreover, because self-employed individuals can reduce their net income through legitimate deductions, their CPP contributions may be lower than the maximum. Planning ahead for this dual-rate obligation is essential to avoid cash flow surprises at tax time.
