The Core Mathematics of Canadian Account Selection
1. The FHSA Super-Account Advantage
Introduced by the federal government in 2023, the First Home Savings Account (FHSA) mathematically dominates both the RRSP and TFSA for any Canadian who intends to purchase a home in the next 15 years. Unlike the RRSP Home Buyers' Plan (HBP) which requires mandatory 15-year repayments, qualifying FHSA withdrawals never have to be repaid. Even if you never end up buying real estate, your FHSA assets can be transferred directly into an RRSP on a tax-deferred basis without consuming any of your existing RRSP contribution room.
2. The Marginal Rate Spread Arbitrage
The decision between RRSP and TFSA hinges entirely on a single mathematical comparison: your marginal tax rate today versus your effective tax rate upon withdrawal in retirement. If you earn $105,000 in Ontario today (37.9% marginal tax rate) and expect to live on $55,000 in retirement (24.1% effective rate), every $10,000 deposited in an RRSP generates a guaranteed +13.8% tax arbitrage bonus over a TFSA. Conversely, if you earn $48,000 today, the TFSA is mathematically superior because an RRSP deduction provides negligible tax relief today while creating taxable income in retirement.
3. Old Age Security (OAS) & GIS Insulation
Every dollar withdrawn from an RRSP or RRIF counts toward Net World Income on line 23600 of your T1 return. When your net retirement income exceeds $90,997 (indexed annually), the federal government claws back 15 cents of OAS pension for every dollar earned. TFSA withdrawals are legally excluded from Net World Income, insulating you against OAS clawbacks and preserving income-tested benefits like the Guaranteed Income Supplement (GIS).
