Deliberately drawing down your RRSP in low-income years to fill tax brackets before CPP, OAS, and mandatory RRIF minimums stack up and force you into higher brackets.
The RRSP meltdown (also called bracket filling or RRSP drawdown) is a retirement tax strategy where you intentionally withdraw from your RRSP before you're forced to — specifically in years when your income is low enough that those withdrawals are taxed at a lower rate than they would be later.
The logic is simple: RRSP withdrawals are taxed as income. If you can control when those withdrawals happen, you can control what rate you pay. Early retirement — before CPP, OAS, and RRIF minimums start — is often the ideal window.
Here's the scenario the meltdown prevents. You retire, RRSP converts to RRIF at 71, and suddenly multiple income sources arrive simultaneously:
| Income Source | Taxable? | Starts When |
|---|---|---|
| RRIF minimum withdrawals | Yes — fully taxable | Age 72 (mandatory) |
| CPP | Yes — fully taxable | Your chosen start age |
| OAS ($727.67/mo max, 2026) | Yes — fully taxable | Age 65 minimum (40yr residency for full amount) |
| TFSA withdrawals | No — tax-free | Any time |
| Non-reg capital gains | Partial — 50% inclusion | Any time |
If all three taxable sources hit at once, a modest retiree with a $600K RRIF, average CPP, and OAS could easily find themselves with $60–80K+ in taxable income — in brackets they never needed to be in.
The strategy is to withdraw from your RRSP in the years between retiring and when CPP/OAS/RRIF kick in — typically your 50s and early 60s. You "fill up" lower tax brackets with RRSP withdrawals at low rates, then convert the proceeds to TFSA or non-registered investments.
OAS clawback begins when net income exceeds $93,454 (2026). Every dollar above that threshold triggers a 15% OAS recovery tax — effectively clawing back $0.15 of OAS for every $1 over the threshold.
If you draw down your RRSP before OAS begins, you reduce the RRIF balance that will generate mandatory minimum withdrawals in your 70s and 80s — the same withdrawals that often push income above the clawback threshold.
