Key strategies
TFSA income doesn't count: TFSA withdrawals don't count for either OAS clawback or GIS means testing. Drawing from TFSA is the most tax-efficient source in retirement.
CPP is a GIS killer: Every dollar of CPP reduces GIS by ~$0.50 (single) or split across partners. If you have a small CPP and expect GIS, starting CPP late can be worse than starting early.
Employment exemption: The first $5,000 of employment or SE income is exempt from the GIS income test, plus 50% of the next $10,000. Part-time retirement work up to $15,000 only counts $5,000 toward GIS.
GIS is tax-free: GIS and the Allowance are not taxable and don't raise your marginal rate. OAS is taxable but CPP and RRIF are too — pension income splitting with a lower-income spouse can reduce both income tax and OAS clawback.
Apply for GIS: GIS is not automatic if you filed taxes but didn't receive OAS at the time — apply via Service Canada if you think you qualify. Retroactive payments go back up to 11 months.
Methodology: GIS is tapered linearly to the published Service Canada cutoff for each category — exact Service Canada amounts use two-tier rate tables internally but align at the endpoints. OAS recovery tax follows the standard 15% formula above the net-income threshold ($95,323 in 2026). Rates effective Q2 2026 (Apr–Jun 2026). This is an estimate — apply through Service Canada for your exact benefit.
