Income splitting may not sound romantic, but when you consider how much money it may save you on income tax, it may begin to look that way.
Spousal RRSPs work best when one spouse earns more or has more savings than the other. They can also work well if you expect one spouse to have lower taxable income in later years (typically in retirement).
When a higher-earning spouse contributes to their partner’s spousal RRSP, the higher-earner gets a tax deduction. However, the spouse owns the spousal RRSP and can decide what investments the RRSP will have.
The goal in retirement is for each spouse to have an equal or similar income. This means the couple may pay less tax than if all their retirement savings had been owned only by one of them.
Consider this example:
The following example assumes typical tax rates for different income levels in Canada. Your tax benefits may vary based on your individual circumstances.
- Spouse #1 earns a higher income and has a lot of money saved for retirement.
- Spouse #2 earns a lower income and has less money saved for retirement.
Two scenarios for withdrawals in retirement
If the couple wants to withdraw $70,000 per year during retirement, how they make those withdrawals directly impacts how much income tax they pay.
| Scenario | Who withdraws? | Total withdrawn | Tax outcome |
|---|---|---|---|
| Scenario 1 | Spouse #1 only | $70,000 | Higher tax rate on $70,000 for Spouse #1 |
| Scenario 2 | Both spouses ($35,000) each | $70,000 | Lower tax rate on $35,000 for each spouse |
- Scenario 1: Spouse #1 withdraws the entire $70,000 from their RRSP.
- Tax outcome: Spouse #1 pays income tax on the full amount. This could put them in a higher tax bracket, meaning they lose more of their savings to income tax.
- Scenario 2: Spouse #1 contributes regularly to Spouse #2’s spousal RRSP, and the couple splits the withdrawals evenly.
- Tax outcome: Instead of one person withdrawing $70,000, each spouse withdraws $35,000 from their respective RRSPs.
- Benefit:
- Both people benefit from the basic personal amount ($15,705 for most taxpayers in 2024). This is a non-refundable tax credit that both spouses could claim.
- By splitting withdrawals, each spouse pays tax on $35,000 rather than one person being taxed on $70,000. This may lead to both spouses’ income being taxed in a lower tax bracket, meaning they might pay less income tax, keeping more of their retirement savings.
Important consideration: Attribution rules
Withdrawals from a spousal RRSP must not trigger the three-year attribution rule to avoid taxation back to the contributing spouse.
