Understanding Old Age Security (OAS) in Canada
What is Old Age Security?
Old Age Security (OAS) is one of Canada's primary retirement income programs. Unlike CPP, OAS is funded through general government revenues and does not depend on employment contributions.
Full vs Partial OAS
The amount of OAS received depends on Canadian residency history after age 18. Individuals with fewer qualifying years may receive partial benefits.
OAS Deferral Strategy
Canadians may delay OAS beyond age 65 in exchange for permanently higher monthly benefits. This strategy may benefit those with longer life expectancy or ongoing employment income.
Understanding OAS Clawback
The OAS Recovery Tax reduces benefits for higher-income retirees. Careful retirement income planning can help reduce clawback exposure.
OAS, CPP and GIS Together
Most retirees receive retirement income from multiple sources. Coordinating CPP, OAS, GIS, RRIF withdrawals and pensions can improve tax efficiency and retirement income stability.
