How CPP works for self-employed Canadians — rates, CPP2, deductions, and what you actually pay.
The Canada Pension Plan (CPP) is a mandatory retirement savings program. Employees contribute at one rate, and their employer matches it. Self-employed workers have no employer — so they pay both sides themselves.
CPP contributions are calculated on your net self-employment income (after deducting business expenses) up to the Year's Maximum Pensionable Earnings (YMPE). For 2025, the YMPE is approximately $71,300. There is also a basic exemption of $3,500 — CPP is not charged on the first $3,500 of earnings.
| Contribution Type | Rate | Max Earnings (Approx.) |
|---|---|---|
| CPP1 — Employee portion | 5.95% | $71,300 YMPE |
| CPP1 — Employer portion (self-employed pay this too) | 5.95% | $71,300 YMPE |
| Total CPP1 — Self-employed | 11.9% | $71,300 YMPE |
| CPP2 — additional contribution | 4% each side = 8% combined | ~$73,200 (Year's Additional Maximum) |
Net income between the YMPE (~$71,300) and the Year's Additional Maximum Pensionable Earnings (~$73,200) is subject to CPP2. The CPP2 combined rate for self-employed is 8%.
CPP1 maximum: ($71,300 − $3,500) × 11.9% = approximately $8,068
CPP2 maximum: ($73,200 − $71,300) × 8% = approximately $152
Total maximum CPP for a self-employed gig worker in 2025: approximately $8,220
This is a significant tax cost. If you earn $60,000 net from gig work, you'll pay approximately $6,718 in CPP alone — before income tax.
CPP contributions are calculated on Schedule 8 (CPP Contributions on Self-Employment Income). The result flows to your T1 in two ways:
These two mechanisms together mean that while you pay double CPP, the tax cost is partially offset.
CPP contributions are mandatory for self-employed workers with net income over $3,500. However, they do build real retirement benefits — your CPP retirement pension is based on your lifetime contributions. Paying CPP as a self-employed worker means you will receive a CPP pension in retirement.
You can opt out of CPP contributions if you are 65–70 and already collecting CPP, or if you have a disability — but not simply because you prefer to save elsewhere.
CPP owing is included in your total tax balance due. If your combined income tax + CPP exceeds $3,000 in taxes not withheld at source, quarterly installments are required. CPP can be a large component of installment amounts for gig workers with moderate-to-high income.
