Plain English
When you're close to retirement, the RRSP can backfire. You save tax at, say, 30% when you put money in. But once you retire and your RRSP converts to a RRIF (which must happen by age 71), the government forces you to withdraw a minimum amount every year. If those forced withdrawals push your income above $95,323, your OAS pension gets clawed back at 15% on top of regular income tax. A TFSA doesn't have any of these problems — no forced withdrawals, no tax on what you take out, and it's invisible to the OAS clawback.
You're 63, earning $90,000, and contribute $10,000 to your RRSP — saving $3,148 (31.48% rate). You retire at 65. Your pension plus RRIF minimums total $98,000. The $2,677 above the $95,323 OAS threshold triggers a $402 OAS clawback (15%). Your effective withdrawal rate: 31.48% income tax + OAS penalty. If you'd used a TFSA instead, you'd withdraw the $10,000 with $0 tax and $0 OAS impact.
Show the analysis
Late-stage RRSP contributions face compressed time horizons that collapse the deduction-to-withdrawal spread. If the contributor is at a 30% combined rate and retires within 5 years, RRIF minimum withdrawals (escalating percentages starting at 5.28% at age 72) may push retirement income above the OAS clawback threshold of $95,323. The OAS recovery tax (15% of excess above $95,323) acts as an invisible additional marginal bracket, producing effective withdrawal rates of 35–48%+ versus the 30% deduction captured on entry. The TFSA is categorically excluded from RRIF conversion, minimum withdrawal mandates, and OAS income calculations.
RRSP contribution at age 63: $10,000 at 31.48% = $3,148 saved. Retirement at 65, RRIF conversion at 71. At age 72, minimum withdrawal = 5.28% of RRIF balance. If RRIF balance is $500,000: minimum withdrawal = $26,400. Combined with $75,000 pension: $101,400 income. OAS clawback: ($101,400 − $95,323) × 15% = $912/year. Effective marginal rate on RRIF withdrawal: 31.48% income tax + 15% OAS = 46.48%. TFSA: $0 tax, $0 OAS impact.
Edge cases
- If your expected retirement income is well below $95,323 even with RRIF minimums, the RRSP can still provide value — but the time horizon for tax-sheltered compounding is very short.
- Consider a strategic RRSP meltdown in the early retirement years (age 65–71) by making voluntary RRSP withdrawals at low rates before RRIF conversion forces higher minimums.
