What it means
The Canada Pension Plan, or CPP, is a compulsory retirement scheme funded by contributions from workers and employers. To keep the scheme in proportion, it applies contributions only to earnings up to a ceiling, and that ceiling is the YMPE.
Someone earning above the ceiling does not pay the basic contribution on the extra income. The ceiling is linked to average wages and updated annually, which means it normally rises over time.
Employers and payroll teams therefore need to check the current figures at the start of each year rather than rely on last year's. A payroll system that is not updated will withhold the wrong amounts.
The ceiling also has a role on the benefit side. A retirement pension is built up from a person's earnings in each year compared with the ceiling for that year, so someone who earned at or above the ceiling for decades builds up a larger pension than someone who earned far below it.
That comparison keeps the pension linked to relative earnings over a whole working life. A second, higher ceiling was added when the plan was enhanced.
Earnings between the first ceiling and the second are subject to an additional contribution and add to the enhanced benefit. Payroll staff must apply both limits, and the exact names, rates and amounts should always be checked against the published figures for the year in question.
The reporting also uses a basic exemption, a small amount of annual earnings on which no contribution is calculated. Contributions are worked out on earnings between the exemption and the ceiling.
All figures in the example below are invented for illustration and are not current rates. Self-employed people pay both the employee and employer shares, which makes the ceiling especially visible to them.
Their contributions are calculated on net self-employment earnings, up to the same limits, and they pay at the combined rate. A sole trader planning cash flow should set aside the full amount when estimating their yearly tax bill.
In practice
Real-world examples.
Example
A payroll manager at a Canadian company updates the system in January with the new ceiling and rates. A senior employee reaches the ceiling in October, after which basic contributions stop for the year. The manager checks that the stop date appears correctly on the payslip.
Example
A finance director budgeting employer costs for next year uses the new ceiling to estimate the employer share of contributions. Higher ceilings increase the maximum cost per employee. The extra amount is built into the labour cost forecast.
Example
A high earner changes jobs mid-year, and both employers deduct contributions on the first part of the year as if the person had started fresh. Because the combined deductions exceed the annual limit, the individual claims a refund when filing a tax return. The case shows why the ceiling applies per year and per person, rather than per employer. Payroll teams cannot see the earnings from another employer, so the refund is claimed through the personal tax return.
Formula
Calculation
Contribution = (lesser of earnings and YMPE - basic exemption) x contribution rate
Assume for illustration a YMPE of $70,000, a basic exemption of $3,500 and a contribution rate of 6%. For an employee earning $90,000, the lesser of earnings and YMPE is $70,000, so contributory earnings = 70,000 - 3,500 = $66,500 and contribution = 66,500 x 0.06 = $3,990. For an employee earning $50,000, contributory earnings = 50,000 - 3,500 = $46,500 and contribution = 46,500 x 0.06 = $2,790.Case study
Seen in the real world.
Maple Leaf Staffing is an illustrative, fictional recruitment firm with 200 employees across several provinces. In January the payroll team forgot to update the ceiling, and the system used the previous year's lower figure.
The result was that high earners stopped contributing too early in the year, and the firm under-deducted contributions by about $18,000 in total before the error was found. The company had to correct the records and pay the shortfall, which caused extra work and employee queries.
The finance manager introduced a January checklist that listed every annual payroll parameter with a named reviewer. The firm also asked its payroll provider to confirm the new parameters in writing each year, and kept the confirmations with the payroll records. The illustrative lesson is that annual limits are small numbers with large consequences if they are missed.
Watch out
Common mistakes.
- Using last year's ceiling in the payroll system, which leads to wrong deductions for higher earners.
- Applying the contribution rate to total earnings instead of only the earnings between the basic exemption and the ceiling.
- Forgetting that more than one ceiling now applies, which affects contributions on higher earnings.
Questions
People also ask.
What is the YMPE?
It is the yearly earnings ceiling used by the Canada Pension Plan for contributions and for calculating pension benefits.
Who sets it?
The government sets it each year in line with changes in average wages, so it is published in advance.
Does it affect employers?
Yes, employers match their employees' contributions up to the ceiling, so it influences payroll costs.
