CPP for Self-Employed Canadians
CPP for self-employed Canadians: who must contribute, how the T2125 calculation works, and how to claim your deduction on your T1 return.
If you are self-employed in Canada, CPP for self-employed workers is not optional: once your net self-employment income is above the basic exemption, you generally must contribute to the Canada Pension Plan and report those contributions on your T1 return. Unlike an employee whose employer withholds CPP from every paycheque, you calculate and pay the full contribution yourself when you file.
Who has to contribute to the CPP on self-employment income
You normally have to contribute to the CPP if you are between 18 and 70 and you have net self-employment income above the basic exemption that the CRA applies to pensionable earnings. That includes business profits, fees, commissions, and professional income reported on a T2125. This is a mandatory program for self-employed people, so you cannot simply choose not to participate the way you can opt in or out of EI special benefits.
If you are 65 to 70, you can file an election with the CRA to stop contributing even though you are still working; at 70 and older, contributions generally stop. Income below the basic exemption is not pensionable. If you also hold a T4 job, your employer's deductions count toward the same annual maximum, so you may owe little or nothing on top.
How self-employed CPP contributions are calculated
The key difference for a sole proprietor is that you wear two hats. As a self-employed person you pay both the employee and the employer share of CPP on your pensionable earnings, which is why your effective rate is roughly double what a salaried employee contributes on the same income.
Your contribution is based on net self-employment income after expenses, up to the Year's Maximum Pensionable Earnings (YMPE). A basic exemption amount is carved out first. Above a second, higher ceiling, the first and second additional CPP contributions, often called CPP2, apply to higher earners.
| Factor | Employee | Self-employed (sole proprietor) |
|---|---|---|
| Who pays | You and your employer each pay half | You pay both halves |
| What it is based on | Pensionable employment income | Net self-employment income on Form T2125 |
| How it is collected | Withheld at source by the employer | Calculated on your T1 return and paid with your balance owing |
| Where it is reported | On the T4 slip | On Form T2125 and your T1 return |
| Can you opt out | No | No, apart from limited elections between 65 and 70 |
Contribution rates, the basic exemption, the YMPE, and the CPP2 ceilings are indexed and change over time. Confirm the current figures on the CRA website as of the current tax year before you estimate what you owe.
Reporting and paying CPP when you file your return
You do not remit CPP separately the way an employer remits source deductions. Instead you report income and expenses on Form T2125, Statement of Business or Professional Activities, and the CPP calculation flows into your T1 return. The amount is paid with your balance due, typically by the individual filing deadline in the spring. If your net income is high enough that the CRA expects quarterly payments, you may need to make tax instalments during the year, and those instalments include your CPP. The overall filing process is covered in how to file taxes as a sole proprietor.
How the CPP deduction and tax credit work
Half of what you pay is treated as the employer's share, and it is tax-deductible. You claim that deduction on your T1 return as the deduction for CPP or QPP contributions on self-employment and other earnings, which reduces your net income. The other half, your employee share, is not deductible, but it generates a non-refundable tax credit that lowers the tax you owe. The result is partial relief rather than a full deduction, so the self-employed CPP bill still exceeds what an employee pays. For the wider list of write-offs, see sole proprietorship tax deductions in Canada.
CPP2 and higher earnings
The enhanced CPP system adds a second layer of contributions on earnings above the original maximum. Self-employed people pay both portions of CPP2 as well. If your net self-employment income sits well above the YMPE, budget for the additional amount and check the current thresholds rather than assuming last year's rate still applies.
CPP, QPP, and programs it is not
If you live in Quebec, you contribute to the Quebec Pension Plan (QPP) instead of the CPP, under rules administered by Revenu Québec. The amounts are broadly similar, but thresholds and equivalency rules differ. CPP is also separate from EI: self-employed people are not automatically covered and must opt in to the special benefits program, explained in EI for self-employed Canadians. If you incorporate, the CPP picture changes again because salary and dividends are treated differently.
Records, deadlines, and confirming current numbers
- Keep your T2125, receipts, and expense records for at least six years in case the CRA reviews your return.
- Check CRA My Business Account for your contribution history and any balance owing.
- Review the CPP rate, basic exemption, YMPE, and CPP2 ceilings on canada.ca each year.
- Get professional advice if you have both employment and self-employment income or are nearing 65.

Frequently asked questions
Do self-employed people have to pay CPP?
Yes. If your net self-employment income is above the basic exemption and you are between 18 and 70, contributing is mandatory. You report the income on Form T2125 and the calculation flows onto your T1 return. Because you pay both the employee and employer portions, the amount is higher than for a salaried employee earning the same income. Elections to stop contributing are available between ages 65 and 70.
How much CPP do I pay as a self-employed person in Canada?
It depends on your net self-employment income, your age, and the current CPP rate, basic exemption, and Year's Maximum Pensionable Earnings. Pensionable earnings are capped at the YMPE, with the additional CPP2 layer applying above a second ceiling. Since you pay both shares, your effective rate is roughly double the employee rate. Confirm the current amounts on the CRA website before estimating your bill.
Can I opt out of CPP if I am self-employed?
Generally no. CPP is mandatory for self-employed people with pensionable earnings, unlike EI special benefits, which are entirely opt-in. The main exceptions are that you can file an election to stop contributing when you are 65 to 70, contributions generally stop after 70, and income below the basic exemption is not pensionable. Quebec residents contribute to the QPP instead.
Is my self-employed CPP contribution tax deductible?
Partly. The employer-equivalent half is deductible on your T1 return, reducing your net income. The employee half is not deductible, but it creates a non-refundable tax credit that lowers the tax you owe. You therefore receive partial tax relief rather than a full deduction. The CRA works out the split based on the self-employment income you report.
