Taxed back to the wrong spouse

a Stratford equalization plan and the spousal RRSP attribution rule

A Stratford equalization plan assumed a spousal RRSP could simply be withdrawn by the lower-income spouse toward their own share, with only withholding tax to plan around. Because the last contribution fell inside the federal 3-calendar-year attribution window, the withdrawal would instead be taxed back to the CONTRIBUTING spouse under the Income Tax Act's own spousal RRSP rule -- not the spouse actually receiving the cash.

The client

A couple separating in Stratford held a $560,000 matrimonial home carrying a $310,000 mortgage, splitting the equity 50/50 under their separation agreement.

The problem

Years earlier, the higher-income spouse had contributed to a spousal RRSP in the lower-income spouse's name, an ordinary income-splitting strategy. The couple's equalization plan had the lower-income spouse withdraw $40,000 from that RRSP toward their own share, assuming only withholding tax applied to the withdrawal, the way any RRSP withdrawal is normally taxed.

What the attribution rule actually does

  • The Income Tax Act attributes a spousal RRSP withdrawal back to the CONTRIBUTING spouse, not the annuitant who withdraws it, if made within the same or the two preceding calendar years of any contribution
  • The last contribution to this RRSP fell inside that 3-calendar-year window
  • The withdrawal would have created an unplanned tax bill for the higher-income, contributing spouse -- not the departing spouse actually receiving the $40,000

Both spouses had assumed the RRSP was simply the departing spouse's own money to draw on. Whose tax return it would actually land on was the real question.

The numbers

Once the RRSP was set aside, funding the full equalization through the refinance was ordinary buyout arithmetic.

Funding the equalization without the spousal RRSPAmount
Existing mortgage balance$310,000
Equalization buyout share (50% of $250,000 equity)$125,000
New refinance balance$435,000
Total debt serviceFigure
Payment at the qualifying rate (6.95%), 25 years$3,033/mo
Property tax + heat$485/mo
Car loan$245/mo
Total debt service42.3%

42.3% is comfortably inside range on the keeping spouse's own income alone, consistent with how average mortgage payments run across Canada. Funding the full amount through the refinance, rather than crediting a $40,000 RRSP withdrawal against it, was a deliberate choice to avoid an uncertain tax exposure -- not a sign the file was in trouble.

The solution

A mortgage agent licensed under Ontario's Mortgage Brokerages, Lenders and Administrators Act worked alongside the couple's family lawyer and accountant once the attribution question surfaced.

First, had the accountant confirm the date of the RRSP's last contribution against the 3-calendar-year attribution window, rather than assuming a standard withholding-tax treatment applied.

Second, set the planned $40,000 spousal-RRSP withdrawal aside from this closing entirely, rather than accept an unplanned, uncertain tax exposure for the contributing spouse.

Third, sized the refinance to fund the full $435,000 equalization amount directly, leaving the RRSP withdrawal, if the couple still wants it, for a date outside the attribution window.

The outcome

The equalization refinance funded at 4.95%, at 42.3% total debt service on the keeping spouse's income alone, with the spousal RRSP question resolved by simply not touching it this closing.

Because this file is an uninsured equalization refinance, CMHC's ratio maximums do not apply directly; the 42.3% figure is informational.

What to take from this file

  • 01A spousal RRSP withdrawal can be taxed back to the CONTRIBUTING spouse, not the person withdrawing it. The Income Tax Act's attribution rule applies within a 3-calendar-year window of any contribution.
  • 02Check the date of the last contribution before assuming a withdrawal is simply the annuitant's own money to use. A standard withholding-tax assumption misses the attribution question entirely.
  • 03When an RRSP's tax treatment is uncertain, fund the equalization directly instead. A larger refinance with a known, calculable cost beats a smaller one with an unplanned tax bill attached.
  • 04Involve the couple's accountant on any equalization plan that touches a registered account. A family lawyer's separation agreement and an accountant's tax read need to agree before the numbers are finalized.

Sources

Every regulatory figure in this file traces to one of these primary sources. Client details and anything that varies by lender are illustrative, as flagged below.

Illustrative in this file — lender-specific, not rules:

  • 4.95% contract rate — rates move daily; not a quote.
  • the $40,000 planned RRSP withdrawal — the size and timing of any RRSP contribution or withdrawal is set by the individual spouses and plan administrator, not by a standard formula.
  • the TDS figure — this file is an uninsured equalization refinance, so there is no CMHC ratio ceiling -- the number is informational.
