An Example of Pre-Retirement vs. Post-Retirement Income Splitting

By splitting income with a spouse, the higher income taxpayer can reduce net income and taxable income. Here’s a clear comparison of pre-retirement vs. post-retirement income splitting in Canada, focusing on how the rules, flexibility, and tax savings differ.

Pre-Retirement Income Splitting

Before retirement, Canada has strict attribution rules, so income splitting options are more limited and require planning.

Spousal RRSP Contributions

  • Higher-income spouse contributes to a spousal RRSP.
  • Contributor gets the deduction (at their high tax rate).
  • Withdrawals later are taxed in the lower-income spouse’s hands (if 3-year attribution rule is respected).

Best for: Long-term planning when one spouse expects lower retirement income.

Prescribed Rate Loans

  • Higher-income spouse lends money to lower-income spouse at the CRA prescribed rate.
  • Investment income is taxed to the lower-income spouse.
  • Must charge and actually pay interest annually to avoid attribution.

Best for: High-income earners with substantial non-registered investments.

Business Income Planning (TOSI rules apply)

Income paid to family members through private corporations is heavily restricted under Tax on Split Income (TOSI) rules.

Reality: Income splitting with adult children is often limited unless they are actively involved.

CPP Sharing (if both contributed)

Couples can share CPP retirement benefits based on years lived together.

Limited impact pre-retirement, more relevant once benefits start.

Post-Retirement Income Splitting

After retirement, income splitting becomes much easier and more powerful.

Pension Income Splitting (Major Advantage)

Up to 50% of eligible pension income can be allocated to a spouse on the tax return.

Eligible income includes:

  • RRIF payments (age 65+)
  • Defined benefit pensions
  • Annuity payments

This does not require transferring assets — it’s an annual tax election.

Benefits:

  • Immediate reduction of marginal tax rates
  • May reduce OAS clawback
  • Allows both spouses to claim pension income credit

This is often the most impactful splitting tool available.

CPP Pension Sharing

Canada Pension Plan benefits can be shared based on time together during contributory years.

  • Reduces tax burden if one spouse receives significantly more CPP.
  • Can lower marginal rate exposure.

RRIF Withdrawal Planning

Withdraw strategically:

  • Split up to 50% once age 65+
  • Coordinate withdrawals to equalize income streams

Where Income Splitting Is Most Powerful

Income splitting is generally more effective after age 65, especially when:

  • One spouse has a large defined benefit pension
  • RRIF withdrawals are substantial
  • One spouse is at risk of OAS clawback
  • There’s a significant income imbalance

Pre-retirement splitting is more about long-term planning, while post-retirement splitting delivers immediate tax reduction.
