OAS Clawback Calculator (Recovery Tax)

What Is the OAS Clawback (Recovery Tax)?

The Old Age Security (OAS) Recovery Tax — colloquially called the "OAS clawback" — is a tax under Section 180.2 of the Canadian Income Tax Act that reduces or eliminates OAS pension payments for higher-income seniors. The recovery tax applies at 15% of the amount by which your net world income exceeds the annual threshold. For 2026, the threshold is $93,454 (indexed annually). The clawback fully eliminates OAS at approximately $151,668 for individuals aged 65-74 and $157,490 for those 75+ in 2026 (source: canada.ca OAS recovery tax).

The clawback is applied two ways: (1) Service Canada estimates your repayment based on prior-year T1 and reduces monthly OAS payments accordingly via "OAS recovery tax" deduction at source; (2) actual reconciliation happens when you file your T1 — overpayment refunded, underpayment owed. The recovery tax is technically a tax, not a benefit reduction, so it appears on your T1 as both an income inclusion (gross OAS) and a tax deduction (recovery tax).

2026 Thresholds and Rates

For the 2026 tax year (income earned during 2026), the OAS recovery tax threshold is $93,454. Every dollar of net world income above this amount triggers $0.15 of recovery tax. Once income reaches the full reduction threshold (~$151,668 for ages 65-74, ~$157,490 for ages 75+), 100% of OAS is recovered — you receive nothing. The maximum monthly OAS pension in early 2026 is $727.67 for ages 65-74 ($8,732/year) and $800.44 for 75+ ($9,605/year), per Service Canada quarterly indexation (source: canada.ca OAS payments).

The threshold and full reduction points are indexed annually for inflation using CPI. The threshold has risen approximately 3-7% per year recently due to elevated inflation. CPP and QPP retirement pensions, RRSP/RRIF withdrawals, dividend income, capital gains, and rental income all count toward net world income — so high-RRIF-balance retirees are particularly exposed to OAS clawback.

Strategies to Reduce or Avoid OAS Clawback

(1) Defer OAS to age 70 — increase monthly amount by 7.2% per year of deferral (max 36% at age 70), reducing the relative impact of clawback if your income later drops. (2) TFSA over RRSP/RRIF withdrawals — TFSA withdrawals don\'t count as income, so building TFSA balance during working years gives a clawback-free income source in retirement. (3) Pension income splitting — split eligible pension income with a lower-earning spouse to reduce the higher earner\'s income below threshold (Form T1032). (4) RRSP withdrawal timing — draw down RRSPs in lower-income early-retirement years (60-65) before OAS starts at 65, reducing future RRIF mandatory withdrawals.

(5) Defer CPP to age 70 as well — increases CPP by 42% but has the same trade-off; useful if you have other income sources to bridge. (6) Capital gains harvesting — realize gains in lower-income years to shift income out of clawback zone. (7) Charitable giving — donations reduce taxable income but only marginally affect the recovery tax calculation. (8) Spousal RRSP contributions during working years to shift retirement income to the lower-earning spouse.

Coordination with Provincial Benefits and CPP

OAS clawback is separate from the Guaranteed Income Supplement (GIS) — GIS is means-tested and only paid to low-income seniors, so it never overlaps with clawback. CPP and QPP are based on contributions during working years and are not subject to clawback (you receive the full earned amount regardless of other income). Some provinces (BC, Ontario, Alberta) have additional senior tax credits that interact with OAS — check provincial rules for your specific situation.
