The Value of Delaying RRSP Withdrawals
We’ve heard that melting down an RRSP early can be valuable when it lowers your future tax rate on RRSP withdrawals later in retirement. But we’ve also heard that delaying RRSP withdrawals so the RRSP can continue growing tax-free is valuable. But not everyone agrees that longer tax-free compounding is valuable. Who’s right? Let’s dig in. We can make mistakes when we try to measure the value of some portfolio choice in isolation. We have to consider all of its effects to draw a correct conclusion. Here’s an example: Scenario 1 (RRSP meltdown) : You withdraw an amount M from your RRSP today. If your average tax rate on the withdrawal is T, you get to keep M(1-T). Scenario 2 (no RRSP meltdown) : In a second scenario, you delay RRSP withdrawals for a decade. Your RRSP grows by a factor of R in that decade, and you withdraw MR then. If your future average tax rate on that withdrawal is U, you get to keep MR(1-U). It’s important to note t...
