Pension income splitting can cut your tax bill - but your RRSP timing matters

Pension income splitting lets you shift up to half your eligible pension income to your spouse's tax return. If one of you is in a higher tax bracket than the other, this can save hundreds or thousands in tax each year. The catch: not all retirement income qualifies, and your RRSP withdrawals probably don't count.

Here's what qualifies for pension income splitting. If you're 65 or older: payments from a registered pension plan, RRIF withdrawals, annuity payments from your RRSP, and LIF payments. If you're under 65: only payments from a registered pension plan and survivor benefits from your deceased spouse's RRSP or RRIF.

Notice what's missing: regular RRSP withdrawals. Pull money directly from your RRSP and it counts as regular income, not pension income. That means it can't be split with your spouse, no matter your age.

The RRIF conversion changes everything. Once you convert your RRSP to a RRIF - required by December 31st of the year you turn 71 - those same dollars become eligible for pension income splitting. Same money, different tax treatment.

This creates a timing decision. Take Maria and David in Ontario. Maria earns $85,000 and David earns $45,000. Maria's marginal tax rate is about 31.5%. David's is about 24%. If Maria splits $20,000 of eligible pension income with David, they save roughly $1,500 per year in combined taxes.

But if Maria withdraws that same $20,000 directly from her RRSP before converting to a RRIF, she pays the full 31.5% rate - about $6,300 in tax. No splitting allowed. Convert to RRIF first, then withdraw, and they can split the income for a combined tax bill of about $4,800. The difference: $1,500 per year.

The 2025 RRSP contribution limit is $32,490, but there's no limit on how much pension income you can split - up to 50% of what qualifies. For couples with significant RRSP savings, this can mean splitting $30,000, $50,000, or more each year.

Early RRIF conversion makes sense for some people. You can convert your RRSP to a RRIF any time after age 65, not just at 71. If you're retired, your spouse is in a much lower tax bracket, and you need the money anyway, converting early unlocks pension income splitting six years sooner.

The exact tax savings depend on your incomes and province. TaxSplit.ca will show you how much pension income splitting saves based on your specific situation.

One more complication: if you die before your spouse, your RRSP can roll to their RRSP tax-free. But if they're under 65 and start withdrawing, those dollars lose the pension income splitting benefit until they turn 65 or convert to a RRIF.

The bottom line: if you're married and one spouse will have significantly more retirement income, pension income splitting matters. Plan your RRSP withdrawal timing accordingly - sometimes waiting for RRIF conversion saves real money.
