What is the 2026 OAS clawback threshold?

The OAS Recovery Tax (clawback) typically begins when your net world income exceeds a specific threshold, projected to be approximately $91,000 for 2026. For every dollar earned above this limit, your OAS benefit is reduced by 15 cents.

Can I receive OAS if I haven't lived in Canada for 40 years?

Yes. To receive OAS within Canada, you must have lived here for at least 10 years after age 18. Your payment will be pro-rated at 1/40th of the full pension for each year of residency.

Is it better to delay OAS until age 70?

Delaying OAS increases your monthly benefit by 0.6% for every month you wait past 65, up to a maximum increase of 36% at age 70. This acts as a form of longevity insurance for those in good health.

Strategic Guidelines

Effective retirement planning requires tax-bracket smoothing. OAS is a taxable benefit, meaning its timing should be coordinated with RRSP/RRIF drawdowns.

Projections are based on current CRA and Service Canada legislation. Clawback thresholds are indexed to CPI and subject to annual adjustment.
