One of the most common misconceptions about retirement is that taxes stop mattering once you leave work. The reality is that retirement income in Canada is subject to income tax — sometimes at the same rates as working income, sometimes at more favourable rates depending on the source. Understanding how each type of retirement income is taxed, and how to structure your income to minimize taxes, can add tens of thousands of dollars to your lifetime after-tax wealth.
CPP retirement benefits are fully included in your taxable income. They are taxed at your marginal rate combined (federal + provincial). CRA does not automatically withhold income tax from CPP payments. If your CPP income will result in a significant tax bill, you can request voluntary withholding by contacting Service Canada, or set aside 15-20% yourself and pay quarterly installments.
OAS is fully included in taxable income and taxed at your marginal rate. Like CPP, no withholding at source unless requested. Additionally, if your net income exceeds approximately $90,997 in 2025, OAS is subject to the clawback (recovery tax) at 15% of income above the threshold.
Guaranteed Income Supplement payments are completely non-taxable. GIS does not appear as income on your tax return. This makes GIS the most tax-advantaged income source available to eligible seniors.
All RRIF withdrawals are fully included in taxable income. They are treated identically to employment income for tax purposes. At age 65+, RRIF withdrawals qualify as "eligible pension income" for the pension income tax credit ($2,000 eligible) and can be split with a spouse under pension income splitting rules.
Defined benefit pension payments are fully taxable as income. At any age, DB pension income qualifies for pension income splitting. At 65+, DB pension income also qualifies for the $2,000 pension income tax credit.
Life annuity payments from a registered pension or RRSP are fully taxable. Prescribed annuities (from non-registered funds) have a split treatment: only the interest portion is taxable each year, with the return-of-capital portion being tax-free. This can make prescribed annuities from non-registered funds more tax-efficient than RRIF withdrawals.
Completely tax-free. Zero income inclusion. No effect on any tax credits, OAS clawback, or government benefit calculations. This is the single most tax-efficient source of retirement income available.
Canadian eligible dividends (from most publicly traded Canadian corporations) receive a dividend tax credit that reduces the effective tax rate below the equivalent income tax on the same dollar amount. For example, $100 of eligible dividends may be taxed at an effective rate of 20-25% even in a 33% bracket due to the gross-up and credit mechanism.
Capital gains are included in income at a 50% inclusion rate. If you sell a stock and gain $20,000, only $100 is added to your taxable income. The effective capital gains tax rate is therefore half your marginal rate. Capital gains are the most tax-efficient form of investment income in a non-registered account.
Interest from GICs, bonds, and savings accounts is fully included in taxable income — the least tax-efficient form of investment income. Interest in a TFSA is tax-free; in a non-registered account, it is taxed at full marginal rates. This is why holding GICs and bonds in RRSPs/RRIFs or TFSAs is often preferable to holding them in non-registered accounts.
Federal income tax rates for 2025:
Add provincial income tax on top (ranging from 5-22% depending on province and income level) for combined marginal rates.
Every Canadian can earn approximately $16,129 (federal, 2025) before paying any federal income tax. Provinces have their own basic personal amounts. This means a couple can receive up to $32,258 in total income before federal tax applies at all.
Canadians aged 65 or older can claim the Age Amount federal tax credit on up to $8,396 of income (2025), worth a credit of approximately $1,259 federally. This phases out at higher incomes, reducing by 15% for every dollar of net income above approximately $44,325. At approximately $100,000 net income, the Age Amount is fully phased out.
The first $2,000 of eligible pension income qualifies for a pension income credit of 15% federally (worth $300). Provinces also provide a matching credit. Both spouses can each claim the $2,000 credit if they each have eligible pension income.
Medical expenses exceeding 3% of net income (or approximately $2,659, whichever is less) qualify for a 15% federal tax credit. For retirees with significant medical expenses, this can provide meaningful relief. Eligible expenses include prescription drugs, dental care, assistive devices, and many other medical costs.
The OAS clawback threshold (~$90,997), the highest federal bracket boundary ($220,000), and provincial surtax thresholds are all points where additional income becomes very expensive in tax terms. Managing total income to stay below these thresholds — using TFSA withdrawals, charitable donations, or pension income splitting — can save thousands per year.
If you have significant non-registered savings, consider a prescribed annuity. These provide predictable monthly income where only the interest portion is taxable — unlike RRIF withdrawals where everything is income. This can be highly tax-efficient for seniors who need predictable income from non-registered assets.
If your total income tax for the year will exceed $3,000 and more than $3,000 was not withheld at source, you may be required to pay quarterly tax installments. Failing to do so results in interest charges. Voluntary installments are also available to avoid a large lump-sum payment at filing.
Even in retirement, filing a tax return is important — and mandatory if you have any taxable income. You must file to:
