Your RRSP Has a Silent Partner

Return to Articles Index

A retired teacher sat down across the desk from us not long into her retirement, slid her statement over, and said what most people say when the numbers have been kind: "I didn't expect it to grow this much."
​
She was pleased. She should have been. But the second thing she said was the one worth writing about: "So I guess I'm fine."
Maybe. We couldn't tell yet — because half of that number wasn't the part we were worried about.
Picture
You have a partner in that account, and you never signed anything.

Here is the part of an RRSP that almost nobody internalizes. The balance on the statement is not entirely yours. Some portion of it belongs to the Canada Revenue Agency, and it has belonged to them since the day you took the deduction. That was the deal. You deferred the tax; you didn't cancel it.

​The uncomfortable feature of that arrangement is how the CRA's share is measured. It isn't a fixed dollar amount that sat still while your investments worked. It's a percentage. So when your account has a strong run, your silent partner's share compounds at exactly the same rate yours does — and the better the run, the larger the eventual bill in absolute dollars.
Take a purely illustrative $600,000 registered balance. If it grows by half over a stretch of good years, you didn't just gain $300,000. You gained your share of $300,000, and your partner gained theirs. Both numbers went up. Only one of them shows up on the statement.

That's not a reason to be sour about good markets. We've written before about why staying invested matters, and nothing here contradicts it. But it does mean a strong stretch creates a planning problem alongside the planning win, and the problem has a deadline.

Why the years right after you stop working are the ones that matter.

There's a stretch in most retirements that we think of as the gap years — after employment income stops, and before everything else switches on. No paycheque. Often no CPP or OAS yet, if you've elected to defer them. No RRIF minimum, because your RRSP hasn't been converted yet. An RRSP must be converted to a RRIF (or annuitized) by the end of the year you turn 71, and from that point the minimum withdrawal is not a choice — it's a percentage of your balance that climbs as you age.

In the gap years, your taxable income is frequently at the lowest point of your adult life. And here's the part that gets missed: that is also the period when you have the most control over what bracket you land in. You can decide what to withdraw and when.
After the RRIF starts and the government benefits are flowing, that control shrinks. Withdrawals become mandatory, layered on top of income you can't turn off. Voluntary withdrawals are taxed at a rate you choose. Forced withdrawals are taxed at whatever rate your other income and the withdrawal schedule hand you.

That's the whole idea, really. Rate certainty now versus rate exposure later.

Filling a bracket on purpose, instead of by accident.

The technique is unglamorous. Rather than defaulting to withdrawing nothing — or later, to the bare minimum — you draw enough from the registered account each year to deliberately use up a lower tax bracket, and you stop before you spill into the next one.
The objection we hear immediately is a fair one: "But I don't need the money."

You don't have to spend it. This is a relocation, not a splurge. Money withdrawn and not needed can go straight into a TFSA, where it grows and comes out with no further tax, or into a non-registered account, where at least the growth is taxed more favourably than a fully taxable withdrawal. The dollars don't leave your household. They just stop sitting in the one account where the CRA's share keeps compounding.

The levers that don't sit still while you do this.

A registered balance doesn't exist in isolation, and a few interacting rules are worth naming plainly.
  • OAS is income-tested. Above an income threshold that is indexed each year, a recovery tax claws back part of the benefit. The mechanism matters more than the number: large mandatory RRIF withdrawals later in life can push income into that zone, which means the effective cost of those dollars is higher than the bracket alone suggests.
  • Pension income splitting is a household-level lever. Eligible pension income — including RRIF income once you reach the qualifying age of 65 — can be split with a spouse on your return, which can move a household from one high income to two moderate ones. It's powerful, and it's one of the reasons a couple should never plan two accounts separately.
  • The survivor problem is the one most people never see coming. When one spouse dies, the survivor typically files as a single taxpayer on a household income that hasn't fallen proportionally — with a fraction of the credits, no splitting, and often a higher marginal rate than the couple ever faced together. A large registered balance is a household risk, not just a personal one.
  • The terminal return is where deferral finally stops. Whatever remains registered is generally deregistered in one shot on a final return, at the top of the schedule. We've written about the RRIF meltdown; this is the same arithmetic, viewed from the far end.

Where this strategy is wrong, and we'll tell you so.

We'd rather be honest than persuasive. Some fair objections.

Isn't paying tax early just paying tax early? Partly, yes. You give up some years of tax-deferred compounding, and that has real value. This is not a case for paying more tax sooner as a virtue. It's a case for rate arbitrage — moving income out of a higher future rate into a lower present one. If there's no spread, there's no strategy.

And for plenty of households there genuinely isn't. If your bracket in retirement will be lower than it is today and will stay lower, the default — defer, convert at 71, take the minimum — is the right answer. We say that in our office regularly.

Drawing down while markets are falling has its own cost, too. That's sequence-of-returns risk, which we've written about at length, and it's a real constraint on how aggressively you accelerate withdrawals in a poor year.

The right answer depends entirely on the spread between your bracket now and your projected bracket later — a projection, with all the humility that word deserves.

The question to actually ask.

Not "how did my account do?" but "what portion of that number is mine, and at what rate will I settle up?"

The account isn't the planning unit. The household is — both spouses, both sets of brackets, and the survivor's return that nobody wants to model. And unlike most decisions in a financial plan, this one has an expiry date. The window closes on a legislated schedule, whether or not the conversation ever happens.
​
If you're somewhere between the last day of work and the year you turn 71, that's the window. Come in and we'll map it out together — what your brackets look like now, what they're likely to look like once everything switches on, and whether there's any spread worth acting on. Sometimes there isn't, and that's a useful answer too.
