Can I deduct CPP contributions as a self-employed person?

Yes — but only partially. As a self-employed person paying both the employer and employee portions of CPP, the CRA splits the tax treatment: **Employer portion (half of your CPP):** Fully deductible as a business expense on line 22200 of your T1 Return. This reduces your taxable income. **Employee portion (the other half):** Qualifies for a 15% non-refundable federal tax credit on line 31000 of your T1. This reduces your tax owing but does not reduce your taxable income. For 2024, if your maximum CPP contribution is approximately C$7,136: - C$3,568 is deductible from income (employer half) - C$3,568 generates a tax credit of approximately C$535 (employee half) This split treatment means your CPP reduces both your taxable income and your tax bill, but in two different ways. Quebec residents pay QPP (Quebec Pension Plan) instead of CPP — the same split deduction principle applies.

• Employer half (~50%) is deductible from taxable income
• Employee half (~50%) gives a 15% non-refundable tax credit
• Total 2024 CPP max: ~C$7,136 for self-employed
• Quebec uses QPP instead of CPP — same split principle
• Deduction claimed on line 22200; credit on line 31000 of T1
