Can you work while collecting CPP? Yes. But depending on your age, you may be legally forced to continue paying into the system, even though you are already drawing from it.
1. The Age Rules for CPP Contributions
The rules for paying into CPP while working are strictly governed by your age.
- Age 60 to 64: If you are working and collecting CPP, you must continue to make CPP contributions. There is no opt-out. Both you and your employer will pay into it.
- Age 65 to 70: You can choose to stop contributing to the CPP. However, to stop, you must fill out form CPT30 (Election to Stop Contributing to the Canada Pension Plan), give a copy to your employer, and send the original to the CRA. If you don't file the form, contributions will continue to be deducted automatically.
- Age 70+: You can no longer contribute to the CPP, even if you are still working. Deductions automatically stop.
2. The Post-Retirement Benefit (PRB)
If you are working and continuing to pay into CPP (either because you are under 65 and have to, or over 65 and chose to), that money does not disappear into a black hole. It goes toward a Post-Retirement Benefit (PRB).
The PRB is a permanent, inflation-indexed addition to your monthly CPP pension. Every year you work and contribute, you earn a new PRB that is added to your pension the following year. You can earn multiple PRBs if you work for several years.
Worked Example: The PRB Math
Robert (62) is collecting his CPP but takes a part-time consulting job earning $35,000 a year. Because he is under 65, he MUST pay CPP premiums.
He will pay roughly $1,800 in CPP premiums for the year. In return, the CRA will calculate a PRB. The following January, Robert will notice his monthly CPP deposit has permanently increased by about $9 to $11 a month.
It takes roughly 13 to 15 years of collecting the PRB to "break even" on the premiums he was forced to pay.
3. The Tax Trap of Working in Retirement
The biggest danger of working while collecting CPP is your marginal tax rate.
Your CPP income, OAS income, RRIF withdrawals, and employment income are all stacked together. If you take a job paying $40,000, that $40,000 sits on top of your existing pension income. You will be taxed on that employment income at your highest marginal rate.
Furthermore, if that employment income pushes your total net income above the $95,000 threshold (in 2026), you will trigger the OAS clawback, effectively paying a 15% recovery tax on top of your marginal income tax.
4. The Strategy: Should You File the CPT30?
If you are 65 or older, should you elect to stop contributing?
Yes, stop contributing if: You have a shortened life expectancy, or you desperately need every dollar of cash flow right now. The ROI on the Post-Retirement Benefit is decent if you live into your late 80s, but terrible if you pass away at 75.
Keep contributing if: Your employer is matching the contributions (which is free money), and you have a family history of extreme longevity.
