Canada's progressive tax system means that a family with one $500K earner pays significantly more tax than a family with two $250K earners. Income splitting strategies legally distribute income among family members in lower tax brackets, reducing the family's total tax burden. Since the 2018 TOSI (Tax on Split Income) rules, the landscape has become more complex — but legitimate opportunities remain for professionals who structure correctly.
| Strategy | Eligibility | Annual Savings Potential |
|---|---|---|
| Spousal salary for legitimate work | Spouse performs real services | $15K-$40K |
| Prescribed rate loan to spouse | Any married professional | $5K-$15K |
| Spousal RRSP contributions | Any married professional | $3K-$8K (deferred) |
| Adult children dividends (if involved) | Children 18+ working in business | $10K-$25K |
| Family trust distributions | Complex; requires proper structure | Varies significantly |
| Pension income splitting at retirement | Age 65+ or pension recipient | $5K-$20K |
The Tax on Split Income rules apply a top marginal tax rate to dividends paid to family members who do not meaningfully contribute to the business. However, several exclusions exist: spouses over 65, family members who work 20+ hours per week in the business, and returns on capital contributed by family members. Proper planning and documentation are essential to defend income splitting arrangements.
