Working part time in retirement: what a few years of earnings can do

Why a few years of earnings matter so much

Part-time work helps a retirement plan in three ways at once. Each year of earnings is a year you don't withdraw from savings. Those savings keep compounding during that time. And the number of years your savings have to cover gets shorter.

The effect is strongest at the start of retirement, when balances are largest and the horizon is longest. Earnings in the first few years also cushion against weak markets at the moment when withdrawals do the most damage, a risk explained in our guide to sequence of returns risk.

A worked example: Wendell in Nova Scotia

Suppose Wendell is 60, single and lives in Nova Scotia. He has $420,000 in his RRSP, $60,000 in his TFSA and $20,000 in a non-registered account. His CPP estimate at 65 is $1,050 a month, he plans to start CPP and OAS at 65, and he wants $40,000 a year after tax. The calculator assumes 5% returns in retirement and 2% inflation, in today's dollars.

If Wendell stops working completely at 60, he draws $20,000 from his non-registered account and about $21,562 from his RRSP in the first year. The plan runs out of savings at 80, leaving 15 years below his spending target. The highest steady spending it supports to 95 is about $34,500 a year.

The same plan with a four-year part-time bridge

Now suppose Wendell finds part-time work that covers his living costs from 60 through 63, so he neither withdraws from nor adds to his savings in those years. He fully retires at 64.

By then his untouched savings have grown to about $582,299. With the same $40,000 spending, his plan now lasts to 95 with about $74,810 left after tax. The highest steady spending to 95 rises to about $41,400 a year, roughly $6,900 more each year for the rest of his life than if he had stopped at 60.

Wendell's example is simplified. Real part-time income can vary, and some years might need a top-up from savings. Still, it shows how much leverage a short bridge can have.

How part-time pay is taxed

Employment income is taxed the same way at any age, and the employer withholds income tax, CPP contributions and Employment Insurance premiums where they apply. Self-employed income works differently, since you pay both halves of CPP contributions and usually remit tax yourself; our self-employed page covers that.

Suppose Wendell earns $24,000 a year from his part-time job and has no other income in those years. The calculator estimates his federal and Nova Scotia income tax at about $2,118, an average rate of about 9%, with a marginal rate of about 23% on extra earnings. Payroll deductions for CPP and EI are separate from that estimate.

Once CPP and OAS begin, earnings stack on top of them. Someone combining a pension, RRIF withdrawals and part-time work can move into higher brackets faster than expected. The retirement tax estimator can show where a given mix lands.

Working while receiving CPP

If you work while receiving your CPP retirement pension, you and your employer may continue to make CPP contributions. Those contributions build a post-retirement benefit, a small lifetime addition to your CPP that is paid the following year. In 2026 the maximum post-retirement benefit is $54.69 a month for a year of contributions.

The rules depend on your age. Between 60 and 65, contributions are generally required if you work while receiving CPP. From 65 to 70, you can generally choose to stop contributing. Because the details and forms matter, it's worth confirming them with Service Canada before you start. Our CPP guide explains the pension itself.

Some people also delay CPP while they're still earning, since each month of delay after 65 increases the pension by 0.7%, up to 42% at 70.

OAS, GIS and other income-tested benefits

Earnings count toward net income for the OAS recovery tax. In 2026, 15% of net world income above $95,323 is recovered from OAS. A modest part-time income is unlikely to reach that level on its own, but combined with a workplace pension and RRIF withdrawals it can.

The Guaranteed Income Supplement is income-tested, so earnings can reduce it. GIS rules include an exemption for some employment and self-employment income, which can soften that effect. Service Canada can confirm how much of your earnings would count. See GIS for low-income seniors for an overview.

Provincial programs for seniors can also be income-tested, so it can help to check how earnings affect any you receive. The provincial benefits hub lists programs by province.

New RRSP and TFSA room from part-time work

Earned income creates RRSP contribution room: 18% of the previous year's earned income, up to the annual dollar limit ($33,810 for 2026), less any pension adjustment. You can contribute to your own RRSP until December 31 of the year you turn 71. A deduction in a year with part-time earnings can be useful if those earnings put you in a higher bracket than you expect later.

TFSA room doesn't depend on earnings. Canadian residents 18 or older with a valid social insurance number accumulate room, $7,000 for 2026, and withdrawals are added back the following year. Our RRSP vs TFSA guide compares the two.

New RRSP room only matters if you have money to contribute and a reason to deduct it. A worker in a low bracket might find the TFSA more useful, since TFSA withdrawals never count as income for OAS or GIS purposes. Someone whose part-time pay pushes them into a higher bracket, on the other hand, may get more from an RRSP deduction now and a smaller RRIF later. The RRSP vs TFSA calculator compares the two with your own rates, and a year-by-year view in the retirement plan model shows how the extra earnings change the whole plan.
