If your annual net world income goes over the fixed threshold, you need to repay 15% of that excess amount to service Canada. This is usually deducted from your next OAS payments or repaid when you file your taxes. You need to pay the OAS recovery tax if both of these conditions apply:

• Your yearly net income crosses the fixed threshold for the tax year. (for example, $90,997 for 2024).
• You live in a country where the non-resident tax rate on Canadian pension payments is 25% or higher.

OAS Recovery Tax Thresholds by Income Year

In this case, repayment is $1,050.45 over the July 2025 to June 2026 period.

How OAS Recovery Tax Deduction Works

When you submit your Return of Income form, the CRA uses your reported net world income to estimate your recovery amount for next tax year. This estimated yearly clawback is then divided into 12 equal monthly parts. Monthly part is deducted from your gross OAS payments. It is deducted until the total clawaback for that year is fully collected.

Full OAS Repayment Thresholds

• Ages 65 to 74: Net income above $148,451 results in a full OAS clawback, reducing OAS payments to $0 for that year.
• Ages 75 and over: Net income above $154,196 results in a full OAS clawback, reducing OAS payments to $0 for that year.

What Income Counts for the Clawback?

All types of income except OAS, GIS, Allowance, Allowance for the Survivor, RDSP, and GST/HST credit.

Deferring Old Age Security Benefits

If you delay your OAS pension after the 65, your monthly OAS Payment increases by 0.6% per month 7.2% per year. The maximum increase is 36% at age 70.
