If you started collecting your Canada Pension Plan (CPP) retirement pension but you’re still working — full-time, part-time, or self-employed — you might be surprised to learn something: your pension doesn’t stop, but you could still be required to keep contributing to CPP. Those extra contributions aren’t wasted. They quietly build a second, smaller pension called the CPP Post-Retirement Benefit (PRB), and it keeps growing every year you contribute, for the rest of your life.
This guide breaks down exactly how the PRB works in 2026: who has to keep contributing, who can opt out, how much the PRB is actually worth, and how to check or start receiving it.
1. What Is the CPP Post-Retirement Benefit (PRB)?
The Post-Retirement Benefit is an extra, separate lifetime pension “top-up” that gets created each year you make CPP contributions while you’re already collecting your regular CPP retirement pension. Unlike your main CPP pension, which is calculated from your entire contributory working history, the PRB is generated from a single year’s worth of contributions at a time. That means each year you work and contribute adds one small new layer to your income.
Here’s the good news: you don’t need to file a separate application to start receiving it. If you contributed to CPP in a given year while already receiving your pension, Service Canada automatically starts paying the resulting PRB the following January.
The PRB is available whether you’re an employee with a T4 or self-employed and paying both the employer and employee portions of CPP.
2. Contribution Rules by Age: 60-65 vs. 65-70
Whether you’re required to keep contributing to CPP after you start your pension depends entirely on your age. There are three distinct stages:
| Age Range | Contribution Status | PRB Generated? |
|---|---|---|
| 60 to 64 | Mandatory — you cannot opt out while working and receiving CPP | Yes, automatically |
| 65 to 69 | Optional — you can elect to stop using form CPT30 | Yes, unless you opt out |
| 70 and older | Contributions stop automatically | No — PRB generation ends |
One more thing worth knowing: unlike the U.S. Social Security system, CPP has no earnings test. There is no income cap that reduces or withholds your CPP retirement pension because you’re earning employment or self-employment income. You can earn as much as you want and your existing CPP pension keeps paying in full — the only question is whether new contributions are mandatory, optional, or stopped.
3. How to Opt Out: Form CPT30
Once you turn 65, if you’d rather keep your full paycheque instead of continuing to contribute, you can file form CPT30 (“Election to Stop Contributing to the Canada Pension Plan, or Revocation of a Prior Election”). A few practical details:
- You must give a copy of the completed form to each of your employers, and keep a copy for your own records with the CRA.
- The election generally takes effect the first day of the month after you file it.
- If you change your mind later — for example, if you want to resume building PRB credits — you can revoke the election and start contributing again, also using the CPT30 form.
- This option is only available from age 65 onward. Between 60 and 64, contributions remain mandatory regardless of how much CPP you’re already collecting.
4. How Much Is the PRB Worth?
Two factors determine the size of each year’s PRB: how much you earned and contributed that year, and your age when the resulting PRB starts being paid. Contributing at a higher income level (closer to the year’s maximum pensionable earnings) generates a larger PRB than contributing on a lower income.
A simple example: Say two people both keep working at age 66 and contributing to CPP for one more year. Person A earns close to the year’s maximum pensionable earnings, so their contribution generates close to the maximum possible PRB add-on for that year. Person B earns roughly half that amount, so their contribution generates roughly half the PRB add-on that Person A gets. Neither one applies separately — both amounts are simply added to their monthly CPP deposit starting the following January.
Each year’s PRB, once it starts, is paid for life and is indexed to inflation annually — just like your regular CPP retirement pension. It accrues even if you’re already receiving the maximum possible regular CPP retirement pension, since the PRB is calculated separately.
5. How the PRB Interacts With Your Regular CPP Pension
The PRB isn’t a separate cheque or deposit — it’s added automatically on top of your existing monthly CPP payment. On your tax slip (T4A(P)), it shows up as its own line item, but you receive it together with your regular pension in a single deposit.
Because a new PRB is generated for every year you contribute while collecting CPP, working several more years after starting your pension means several PRB “layers” stack on top of each other. Someone who works and contributes from age 65 to 69, for instance, could end up with five separate PRB amounts all added into their monthly total.
6. Is It Worth Continuing to Contribute After 65?
This is a genuine trade-off, and there’s no single right answer:
- Continuing to contribute means slightly less take-home pay now (both employee and, if self-employed, employer-side CPP contributions), in exchange for a modest, guaranteed, inflation-indexed addition to your income for the rest of your life.
- Opting out with CPT30 means keeping your full paycheque now, but forgoing that additional guaranteed lifetime income layer.
Which choice makes sense depends on your overall retirement income picture, how many more years you plan to work, and your personal risk tolerance around guaranteed versus flexible income.

7. How to Check Your PRB Amount or Get Started
Because the PRB starts automatically, there’s no application to fill out. Here’s what actually happens and how to track it:
- If you contributed to CPP in a given year while already receiving your CPP retirement pension, the resulting PRB automatically begins the following January.
- You can check your current PRB amount, and get projections based on continued work, by logging into your My Service Canada Account.
- No paperwork is required to start receiving it — the only form involved is CPT30, and only if you want to stop contributing after age 65.
Frequently Asked Questions
Do I need to apply separately for the PRB?
No. If you contribute to CPP while already receiving your CPP retirement pension, the resulting Post-Retirement Benefit starts automatically the following January — there’s no separate application.
What happens to my PRB if I stop working again?
Any PRB you’ve already earned keeps being paid for life, indexed to inflation. You simply won’t generate a new PRB layer for years you don’t contribute. If you go back to work later (before age 70), contributing again would generate additional PRB amounts.
Does the PRB affect my OAS or GIS?
The PRB is added to your taxable income like your regular CPP pension, so it can factor into income-tested calculations such as the Guaranteed Income Supplement (GIS) or OAS clawback thresholds. It does not directly reduce your OAS or GIS on its own, but since GIS and the OAS recovery tax are based on total income, an increase in CPP income (including PRB) could affect those calculations. Check your specific numbers with Service Canada or a tax professional.
Can self-employed CPP recipients also generate a PRB?
Yes. Self-employed individuals who continue working and paying both the employee and employer portions of CPP contributions while collecting their CPP pension generate a PRB the same way employees do.
Bottom Line
If you’re between 60 and 64 and still working while collecting CPP, contributions are mandatory — and they’re quietly building extra guaranteed income for you through the Post-Retirement Benefit. Once you turn 65, you get a choice: keep contributing (and keep growing your PRB) or file form CPT30 to stop. Either way, the PRB is paid automatically, requires no application, and adds a small but real, inflation-indexed layer to your CPP pension for as long as you live.
