How Does CPP Work? Contributions, Payments, and Taxes

The Canada Pension Plan is a mandatory public pension: while you work, a percentage of your earnings goes into CPP through payroll deductions or self-employed contributions, and once you retire, CPP pays you a taxable monthly pension for life, indexed to inflation. How much you get depends on how much you contributed, for how many years, and the age you choose to start. The plan also pays disability, survivor, children’s, and death benefits. In 2026, the maximum retirement pension for someone starting at age 65 is $1,507.65 per month.¹

If you work in Quebec, you contribute to the Quebec Pension Plan instead. QPP is a separate but comparable program, and the rules below don’t apply to it directly.²

What You Pay In

Contributions start the year you turn 18 and earn more than $3,500, and they continue until you stop working, start collecting your CPP retirement pension, or turn 70, whichever comes first.³

The first $3,500 of annual earnings is exempt. Above that, you and your employer each pay 5.95% on earnings up to the Year’s Maximum Pensionable Earnings, which is $74,600 in 2026. That works out to a maximum base contribution of $4,230.45 each. If you’re self-employed, you pay both halves for a combined rate of 11.9%.⁴

Since 2024, a second tier of contributions (often called CPP2) applies to higher earnings. In 2026, CPP2 covers the band between $74,600 and $85,000, known as the Year’s Additional Maximum Pensionable Earnings.⁵ Employees and employers each pay 4% on this band; self-employed workers pay 8%.⁴

How Your Pension Is Calculated

Your monthly retirement pension reflects average earnings across your contributory period, which runs roughly from age 18 to the month you start collecting. The formula doesn’t weight every year equally: it drops the weakest ones and rewards steady, higher earnings.

The base calculation automatically excludes up to eight years of your lowest earnings. That cushions periods of unemployment, illness, or schooling. For the enhanced portion of CPP (the layer funded by contributions added since 2019), the formula instead uses your best 40 years of earnings.⁶ You don’t need to apply for either drop-out; both happen automatically.

If your earnings dropped because you were the primary caregiver for a child under seven, you can request the child-rearing provision to exclude those low-earning years from the calculation. This one isn’t automatic. You apply for it and provide your children’s names and dates of birth.

Once your pension starts, Service Canada adjusts the amount every January to reflect changes in the Consumer Price Index.⁷

When You Can Start

The standard age is 65, but you can start as early as 60 or delay until 70. Your choice permanently changes your monthly amount for life.

Starting before 65 reduces your pension by 0.6% for each month early. At 60, the earliest possible date, the reduction is 36% for life. Starting after 65 increases the amount by 0.7% for each month you wait, up to 42% more if you start at 70.⁸

The right timing depends on your health, other income, and whether you need the money now. Someone in good health with other savings who can afford to wait ends up with a substantially larger monthly cheque. Someone who stops working at 60 with no other income may need to start early. The math rewards patience if your circumstances allow it.

Check Your Record and Apply

Before deciding when to start, look at what you’ve actually accumulated. Sign in to My Service Canada Account and open the Canada Pension Plan section. You’ll see your contributions and pensionable earnings for every working year, plus an estimate of what your pension would be if you started at different ages.⁹ Many people are surprised by the number, and it’s better to find that out years before retirement than after you’ve filed.

You can apply up to 12 months before you want payments to start.¹⁰ Applying early doesn’t accelerate your start date. It just gives Service Canada time to process the paperwork so payments begin when you want them to.

Have these ready before you start:

Your Social Insurance Number
Your branch transit number and account number for direct deposit
Information about your current or former spouse or common-law partner
Children’s names and dates of birth if you’re claiming the child-rearing drop-out
Dates and details of any work in another country that has a social security agreement with Canada

The fastest route is online through My Service Canada Account, where much of your information is already filled in; decisions typically come by mail within about 28 days. You can also mail the paper ISP-1000 form to your regional Service Canada processing centre, but paper applications take up to 120 days.¹⁰

If You Keep Working After You Start

Once your CPP retirement pension is flowing, additional work earnings can still grow your monthly income through the Post-Retirement Benefit. Each year of extra contributions produces a small separate payment that’s added to your monthly total for life.

Between 60 and 64, these contributions are mandatory if you’re working and already collecting CPP. From 65 to 70, they’re voluntary. To opt out during that window, you file form CPT30 with your employer. You can change your mind, but only once per calendar year.¹¹

The maximum Post-Retirement Benefit from a single year of contributions in 2026 is $54.69 per month, which equals 2.5% of the maximum retirement pension. Your actual amount is proportional to what you earned. Someone earning half the maximum for a year would add roughly $27.35 per month.¹² These payments are modest individually, but they stack and are indexed to inflation.

Disability, Survivor, and Other Benefits

CPP is more than a retirement plan. If you become disabled, or if a contributor in your family dies, other CPP benefits kick in.

Disability Benefit

The disability benefit pays a monthly amount if you’re under 65 and have a severe and prolonged condition that prevents you from working. You must have contributed in four of the last six years, or three of the last six if you have 25 or more years of contributions.¹³ The maximum monthly amount in 2026 is $1,741.20.¹ Decisions take up to 120 calendar days.¹⁴

Survivor’s Pension

When a CPP contributor dies, their surviving spouse or common-law partner may qualify for a monthly survivor’s pension. The amount turns on the survivor’s age and whether they’re already receiving CPP benefits of their own. A survivor 65 or older who isn’t receiving other CPP benefits gets 60% of the deceased contributor’s retirement pension, up to $904.59 per month in 2026. A survivor under 65 receives a flat-rate portion plus 37.5% of the contributor’s pension, up to $803.54 per month.¹⁵¹

Death Benefit

The death benefit is a one-time lump sum. As of January 2025, the basic amount is $2,500. An additional $2,500 top-up may apply if the contributor died before collecting a retirement or disability pension and left no surviving spouse or common-law partner, bringing the maximum to $5,000.¹⁶ It’s paid to the estate, or if there’s no estate, to the person who paid for funeral expenses, the surviving spouse, or the next of kin, in that order.

Children’s Benefit

Dependent children of a disabled or deceased CPP contributor can receive a monthly flat-rate payment. They qualify if they’re under 18, or between 18 and 25 and attending a recognized school or university full time or part time.¹⁷

How CPP Payments Are Taxed

CPP payments count as taxable income. Nothing is automatically withheld from your monthly cheque unless you ask. If you’re a resident of Canada and want to avoid a large bill at tax time, file form ISP-3520OAS to have a specific dollar amount or percentage deducted from each payment.¹⁸

If you live outside Canada, the default non-resident withholding rate is 25%.¹⁹ Tax treaties reduce this for many countries; the Canada-US treaty caps withholding on periodic pension payments at 15% for US residents.²⁰ Non-residents can also elect under section 217 of the Income Tax Act to file a Canadian return and potentially recover some or all of the tax withheld.

If You’ve Worked in Another Country

Canada has social security agreements with the United States and dozens of other countries. These let you combine credits earned abroad with your CPP contributions to meet the minimum requirements for disability or survivor benefits. Under the Canada-US agreement, US Social Security credits earned after 1965 can fill in gaps in your CPP record, provided you have at least one year of contributions to CPP or QPP.²¹

For the retirement pension specifically, this matters less. A single CPP contribution is enough to qualify for a retirement pension; the amount will simply be proportional to what you paid in.²¹

One other cross-life event worth flagging: if a marriage or common-law relationship ends, the CPP contributions made while you lived together can be divided equally between the two partners. This is credit splitting, and it can change both partners’ future pensions. Marriages that ended on or after January 1, 1987 qualify if you lived together at least 12 consecutive months, with no deadline to apply. Common-law separations on or after January 1, 1987 also qualify, but you must apply within 48 months of the date you began living apart unless your former partner agrees in writing to waive the deadline.²²
