The OAS Clawback Is 15 Cents Per Dollar, Not 30 or 50
The tax line that catches the most confusion in retirement planning sits on page 2 of your Notice of Assessment. It's labelled "recovery tax," and it claws back Old Age Security benefits once your income crosses $93,454. The rate is 15 cents per dollar.
Not 30. Not 50. Fifteen.
That gap matters. A retiree with $110,000 in income sits $16,546 above the threshold. At 15%, the recovery tax takes $2,482 of their annual OAS. If they planned around 30%, they budgeted for $4,964 and left money on the table. If they assumed 50%, a figure that somehow persists in retirement planning forums, they thought they'd lose $8,273 and structured their entire withdrawal sequence to avoid phantom tax.
The numbers compound from there. RRIF withdrawals, rental income, employment bridge income, even the timing decision on when to start CPP: all of it flows through this one rate. Get it wrong and the downstream planning looks rational but solves the wrong problem.
Where the 50% figure comes from
The 50-cent clawback exists. It just isn't for OAS.
The Guaranteed Income Supplement, which sits below OAS in the federal benefits stack, claws back at 50 cents per dollar of certain retirement income including RRSP and RRIF withdrawals. GIS serves lower-income seniors, the 2026 maximum monthly benefit for a single person is $1,086.88, and eligibility phases out entirely well before six-figure income levels. If you're earning enough to hit the OAS clawback threshold, GIS isn't in play.
The confusion happens because both programs appear on the same Service Canada statement, both use the word "clawback," and both adjust with income. They just apply to different groups at different income bands with different rates. Mixing them is like using the small business tax rate to plan your salary: same jurisdiction, wrong bracket.
The planning cost of overestimating
A 65-year-old in Kelowna retiring with $850,000 in RRSPs and a paid-off house faces a sequencing problem. She can draw from non-registered savings, start CPP early, delay RRIF withdrawals, or tap home equity. Each choice carries a different tax load, and the OAS recovery tax sits in the middle of the math.
If she assumes a 30% clawback, her model says stay under the threshold at all costs. That often means deferring RRSP withdrawals, delaying CPP to 70, and living lean in her 60s to preserve OAS. The actual 15% rate changes the trade-off. Crossing the threshold by $20,000 costs $3,000 in recovery tax, but deferring $20,000 of RRSP income to age 72 when the minimum withdrawal percentage is higher can cost more in forced taxation later.
The right answer depends on lifespan, other income, estate goals, and provincial tax brackets. But you can't solve any version of that problem with the wrong clawback rate.
The full picture
OAS begins to recover at $93,454 of net world income in 2025 (adjusted annually for inflation). The clawback runs at 15% until your benefit zeros out entirely, which happens around $153,000 depending on how much OAS you qualified for in the first place. Between those two points, every additional dollar of income costs you fifteen cents of OAS on top of your marginal income tax rate.
That stacks. A British Columbia resident at $100,000 of taxable income pays a combined federal-provincial marginal rate around 38%, plus the 15% OAS recovery. Total marginal rate: 53%. That's steep, but it isn't 68% or 88%, and the width of the band matters when you're choosing which year to realize a capital gain or convert a spousal RRSP.
Retirement tax planning is arithmetic with consequences. The rate is fifteen cents. Build your plan around what's real.
