Why professionals who retire at 60 could trigger an OAS clawback they never saw coming

As of January 1, 2026, Canadians who were 18 or older when the program launched in 2009 have accumulated up to $109,000 in cumulative TFSA contribution room. For a retiree who maximized that room and invested in a diversified portfolio, a TFSA could generate meaningful annual income — entirely invisible to CRA’s clawback calculation.

The strategic implication is significant: every dollar shifted from an RRIF (taxable) to a TFSA (tax-free on withdrawal) reduces future exposure to the recovery tax. This is one reason financial planners often recommend making voluntary RRSP withdrawals in the early 60s — before the mandatory RRIF conversion at 71 — to shrink the future RRIF balance and move assets into TFSA room while income is still relatively low.

How professionals and business owners can structure income to stay below the threshold

For incorporated professionals — doctors, lawyers, accountants — the CCPC adds a layer of planning flexibility that employees do not have. Unlike salaried workers, an incorporated retiree can sometimes choose when and how much income to extract from the corporation, choosing salary, dividends or a combination in amounts designed to stay below the $95,323 line.

Pension income splitting is another option for spouses with significantly different income levels. Under current rules, eligible pension income — including RRIF withdrawals after age 65 — can be split up to 50% with a spouse or common-law partner, reducing the higher earner’s net income and potentially keeping both partners below the clawback threshold.

The earlier you begin to research retirement withdrawal scenarios, the better. Voluntary RRSP drawdowns in the decade before the mandatory conversion at 71 can reduce your RRIF balance and the size of forced withdrawals that follow. A lower RRIF balance at 71 means lower mandatory income — and a longer runway before the clawback threshold becomes a problem.

What to do before 71

Avoiding the OAS clawback is not straightforward for high-income retirees, and in some cases it may not be entirely avoidable — particularly where RRIF balances are very large. But reducing the erosion is achievable with enough lead time.

The key is to run the numbers before the forced conversion arrives. A retirement income model that includes projected RRIF minimum withdrawals, CPP, OAS and any corporate distributions will show where income is likely to land relative to the $95,323 mark. That analysis — run at 60 or 65, not 71 — helps create the window needed to act.

Approximately 5% of OAS recipients have their benefit partially or fully clawed back each year — and that share is growing as accumulated RRSP and RRIF balances drive larger mandatory withdrawals at retirement. The retirees most at risk are those who planned well for accumulation and forgot to plan for the drawdown.

What to do now

• Model your retirement income now: add projected RRIF minimum withdrawals, CPP and OAS together and compare against $95,323 (the 2026 income-year threshold)
• If you are between 65 and 71, consider voluntary RRSP drawdowns to reduce the future RRIF balance — and the size of forced withdrawals that follow
• Maximize TFSA contribution room before retirement — up to $109,000 cumulative as of 2026 for eligible Canadians; TFSA withdrawals have no effect on OAS entitlement
• Ask your adviser about pension income splitting if your spouse has significantly lower retirement income — eligible pension income can be split up to 50% with a spouse
• If you are incorporated, model the optimal mix of salary, dividends and RRIF withdrawals early — structured carefully, corporate income can be staged to stay below the clawback threshold
