Retirement Tax Planning in Canada: Managing RRIF Withdrawals and the OAS Clawback

A retirement savings plan built for accumulation does not automatically work for withdrawal. The rules that governed decades of contributing to an RRSP flip once income starts coming out, and the accounts, pensions, and government benefits a retiree draws from all interact with each other on the same tax return. Get the sequencing wrong and a retiree can hand back thousands of dollars a year in Old Age Security they were entitled to keep.

Retirement tax planning is the work of managing that interaction deliberately, rather than letting the default rules decide it.

Every RRSP must convert to a Registered Retirement Income Fund, or be used to buy an annuity, by December 31 of the year the holder turns 71. Once that happens, minimum annual withdrawals become mandatory. Every dollar withdrawn is fully taxable income, no matter which account it came from.

The minimum percentage rises every year, based on the RRIF’s value on January 1:

On a $500,000 RRIF, that is $26,400 at 71 and $42,550 at 85, even before accounting for any growth in the account. The percentage climbs regardless of markets or inflation, which is why the size of the RRIF at conversion matters as much as the conversion date itself.

There is no minimum age to convert an RRSP to a RRIF, and many retirees deliberately convert and begin drawing down part of their RRSP in their sixties, well before the forced deadline.

This early drawdown strategy is sometimes called melting down the RRSP. The logic is straightforward. In the years between stopping work and the start of CPP and OAS, taxable income is often at its lowest point in retirement. Withdrawing from the RRSP during that window fills up the lower tax brackets that would otherwise go unused, and shrinks the account balance before the mandatory minimums climb into double digits in the later years.

Consider someone who retires at 60 with $400,000 in RRSP savings and no other income until CPP and OAS begin at 65. Left untouched, the account must convert to a RRIF by 71, and the mandatory minimum that year lands on top of full CPP and OAS income, all in the same higher-income years. Withdrawing $20,000 a year instead, from 60 to 65, while there is no other income at all, means that money is taxed in the lowest years of the retiree’s income, rather than stacking later against CPP, OAS, and a larger mandatory RRIF minimum. Over five years, that is $100,000 moved out of the account on more favourable terms, while also shrinking the balance the 71 conversion locks in for the rest of retirement.

Old Age Security is income-tested. For the 2026 income year, once net income passes $95,323, the government claws back 15 cents of OAS for every dollar above that line, and OAS is fully recovered once income reaches roughly $154,751. RRIF withdrawals count in full toward that net income figure.

This is where the accumulation mindset causes real damage. A retiree with a large RRIF who waits until the mandatory minimums spike at 80 or 85 can find those forced withdrawals alone pushing them past the clawback threshold, on top of CPP, OAS, and any other income. The clawback effectively adds 15 percentage points on top of the retiree’s regular tax rate for every dollar in that zone.

TFSA withdrawals are the exception. Because they never count toward net income, drawing from a TFSA instead of a RRIF in a high-income year is one of the simplest ways to stay under the clawback threshold without touching a registered account at all.

From age 65, up to 50 percent of eligible pension income, which includes RRIF withdrawals, can be allocated to a lower-income spouse on the tax return using Form T1032. No money actually moves between accounts; it is a tax attribution only.

Consider a couple where one spouse withdraws $70,000 a year from a RRIF and the other has $15,000 of other income. Without splitting, the full $70,000 is taxed in the first spouse’s hands alone, pushing a large share of it into higher brackets. Electing to split half under Form T1032 moves $35,000 onto the second spouse’s return instead, leaving each spouse reporting a more even amount. Spread across two returns rather than one, less of the household’s combined income lands in the higher brackets, which is where the actual savings come from.

Age 65 also unlocks the pension income tax credit, worth up to $2,000 in federal credit on eligible pension income. RRIF withdrawals qualify; RRSP withdrawals do not, which is one more reason the conversion timing matters and is worth planning rather than defaulting to age 71.

RRIF conversion timing, the OAS clawback, pension splitting, and the choice of which account to draw from all touch the same net income figure on the same return. A decision made about one, taken without checking the others, can undo the benefit of the whole plan. Someone who melts down their RRSP too aggressively in one year can trigger a clawback they would otherwise have avoided. Someone who defers CPP and OAS without adjusting their RRIF withdrawals can end up with several income sources landing in the same high-income year instead of spread across several lower ones.

This is where our broader work on tax planning strategies connects directly to retirement: the account sequencing and income-splitting tools apply, but retirement adds the OAS clawback as a constraint that has to be modeled alongside them, not after.

Retirement tax planning is not a decision made once at 71. It starts with the choices made about tax planning in the years leading up to retirement, and it continues through every year income is drawn from RRIFs, pensions, and government benefits together.
