Short answer
CPP (Canada Pension Plan) is a mandatory statutory deduction taken from most employed Canadians outside Quebec. Your employer deducts a percentage of your pensionable earnings each pay period up to an annual maximum set by the federal government. Both you and your employer contribute; the CRA publishes the current rate and maximum each year. If you reach the annual maximum mid-year, CPP deductions should stop for the remainder of that calendar year.
The CPP deduction appears on virtually every pay stub for employees working outside Quebec. It is not optional — the law requires your employer to withhold it and remit it to the Canada Revenue Agency on your behalf. Understanding how the deduction works helps you spot potential errors and plan for retirement.
Your CPP contribution is calculated on your pensionable earnings, which generally means your gross pay minus a basic exemption amount. The rate and the annual maximum contribution are set by the CRA and change each January. Once your total CPP contributions for the year reach the maximum, your employer is required to stop deducting CPP for the rest of that calendar year.
It is worth checking your year-to-date (YTD) CPP total on each pay stub, especially if you change jobs during the year or work multiple jobs. Overpayments can be recovered through your annual tax return, but catching a consistent error early is easier than waiting for a refund.
What this page helps you check
- Whether a CPP line appears on your pay stub at all
- Whether the deduction amount is proportional to your gross pay
- Whether the YTD CPP total is approaching but not exceeding the annual maximum
- Whether CPP deductions continued after the annual maximum was reached
- Whether a new job has restarted deductions partway through the year
- Whether your reported pensionable earnings match your expected gross pay
- Whether you qualify for an exemption (e.g., you are under 18 or over 70)
- Whether a sudden change in the CPP amount coincides with a pay rate change
How CPP Contributions Are Calculated
CPP contributions are based on your pensionable earnings, not your total gross pay. The CRA allows a basic personal exemption amount each year, and contributions are only calculated on earnings above that exemption. Your employer applies the legislated contribution rate to this net pensionable amount each pay period.
The annual maximum pensionable earnings (YMPE) is announced by the federal government each fall for the following year. Once the total of your CPP contributions across all pay periods reaches the annual maximum contribution, no further CPP should be deducted that calendar year. Your pay stub should show both the current-period CPP amount and a running YTD total so you can track where you stand.
Who Is Exempt from CPP
Not all employees pay CPP on every dollar. Employees under 18 years of age are not required to contribute. Employees who are 70 or older are also exempt. Employees who are already receiving a CPP retirement or disability pension and are between 65 and 70 may elect to stop contributing by filing a CPT30 form with their employer. If you believe you fall into an exempt category, check with your employer or the CRA to confirm whether the exemption has been applied correctly.
Self-employed individuals pay both the employee and employer portions of CPP, which is handled through their annual tax return rather than through payroll deductions. If you are a contractor rather than an employee, no CPP should normally appear on invoices or remittances made to you directly.
Reading CPP on Your Pay Stub
Look for a line labelled "CPP," "CPP contribution," or "Canada Pension Plan." Beside it you should see the amount deducted this pay period and, ideally, a YTD total. Some pay stubs show pensionable earnings as a separate line, which allows you to verify the math.
If CPP is missing entirely and you are an eligible employee, that could indicate a payroll setup error. If the amount seems unusually high or low compared to previous pay periods and your pay rate has not changed, it may be worth asking payroll for a breakdown. A single unexpected result does not automatically mean an error — a retroactive correction or one-time catch-up can cause a spike — but a pattern of unusual amounts deserves follow-up.
What Happens at Year-End
At the end of the year, your T4 slip will show your total CPP contributions in Box 16. This figure should match the YTD total on your last pay stub of the year. If you worked for more than one employer in the year and each deducted up to the maximum separately, you may have over-contributed overall. The excess is refundable when you file your income tax return.
If your T4 shows CPP contributions that differ significantly from what your pay stubs show, or if Box 16 is missing entirely, that is worth clarifying with your employer before you file.

Common red flags worth checking
These do not automatically mean there is an error. They are simply lines worth a closer look, or worth asking payroll to explain.
CPP deductions continue past the annual maximum
Once your YTD CPP contributions reach the annual maximum set by the CRA, deductions should stop. If they continue into the later months of the year, this could be a payroll configuration issue worth raising.
No CPP line on your pay stub as an eligible employee
If you are between 18 and 69, employed, and not receiving a CPP pension, a missing CPP deduction may indicate a payroll setup error. Confirm with your employer or HR.
CPP amount changes significantly without a pay rate change
A large unexpected jump or drop in your CPP deduction when your pay rate has not changed could reflect a correction, a data entry error, or a change to your pensionable earnings classification. Ask payroll to explain the change.
Pensionable earnings shown are much lower than gross pay
Some earnings categories are excluded from CPP pensionable earnings, but if the gap seems large, it may be worth confirming the classification is correct for your type of pay.
T4 Box 16 does not match your final YTD total
Your T4 CPP figure should match your last pay stub YTD. A discrepancy could indicate a reporting error that may affect your tax return and future CPP entitlements.
CPP deducted after age 70
Employees aged 70 and over are exempt from CPP contributions. If deductions are still appearing after you turn 70, your employer may need to update your payroll record.

Calm, specific questions get clearer answers. You can copy any of these, or build a full message with the Payroll Message Generator.
- “Can you show me how my pensionable earnings are calculated for CPP purposes?”
- “Why did my CPP deduction change this pay period when my base salary did not change?”
- “My YTD CPP total appears to have passed the annual maximum — why is CPP still being deducted?”
- “I worked for another employer earlier this year. How will that affect my CPP contributions with you?”
- “I am over 65 and receiving CPP — can you explain whether I should be contributing or whether I can elect to stop?”
- “Can you confirm that my pensionable earnings figure on my pay stub matches what will be reported on my T4?”
Frequently asked questions
Is CPP deducted from every paycheque?
Yes, for eligible employees, CPP is deducted each pay period until the annual maximum contribution is reached. After that point, no further CPP should be deducted for the rest of the calendar year.
What is the current CPP contribution rate?
The CRA sets the CPP contribution rate each year. Because rates change annually, always check the CRA website for the current rate rather than relying on figures from a previous year.
Can I opt out of CPP?
Most employees cannot opt out of CPP. However, employees between 65 and 70 who are already receiving a CPP pension may elect to stop contributing by filing a CPT30 form with their employer.
What if I overpaid CPP because I had two jobs?
Each employer deducts CPP independently up to the maximum. If your combined contributions exceed the annual maximum, you can claim a refund of the excess on your personal income tax return (Schedule 8).
Does CPP appear on my T4?
Yes. Your total employee CPP contributions for the year appear in Box 16 of your T4 slip. This should match the YTD total on your final pay stub of the year.
Are CPP contributions tax-deductible?
Employee CPP contributions generate a non-refundable federal tax credit, which reduces the income tax you owe. They are not a deduction from income in the same way as RRSP contributions, but they do reduce your tax payable.
I am under 18. Should CPP be deducted from my pay?
No. Employees under 18 are exempt from CPP contributions. If CPP is appearing on your pay stub and you are under 18, let your employer know so they can correct the payroll setup.
Does the basic exemption amount affect my CPP deduction?
Yes. The CRA sets a basic annual exemption amount for CPP purposes. CPP is only calculated on pensionable earnings above this exemption, which is why your CPP deduction is slightly less than the rate multiplied by your full gross pay.
