What is the Old Age Security (OAS) Calculator?
Old Age Security (OAS) is a federal pension paid to Canadians 65+ who have lived in Canada for at least 10 years after age 18. The full benefit requires 40 years of residency. You can defer OAS from 65 to 70 to receive a 0.6% monthly increase (max 36% at 70). Higher-income retirees face an OAS recovery tax (clawback) starting at $90,997 in net income in 2025.
