TOSI Screener + Prescribed-Rate Loan

Which family-income exceptions actually survive TOSI — and what a prescribed-rate loan saves on your numbers.

★ CHAPTER BRIEF

Since 2018, TOSI taxes most family dividends at the top rate — unless an exception survives: the excluded business (≈20 hours/week of real work), excluded shares (10% votes-and-value, generally unavailable to professional corps), or the age-65 spousal opening. The structure that still works cleanly for many families is the prescribed-rate loan — Michael’s $500,000 move.

The screener walks the exceptions in the order the rules test them. Be honest with the hours: the CRA audits “regular, continuous, substantial” with timesheets in hand, and a professional corporation closes the excluded-shares door regardless of share structure.

The loan sidesteps TOSI entirely because the family member earns investment income on loaned capital rather than receiving dividends. Lock the prescribed rate at inception, pay the interest by January 30 every year without exception, and the spread between portfolio return and prescribed rate is taxed at the family member’s low rate — year after year.

★ KEY POINT
Salary was never TOSI: paying a family member a reasonable wage for genuine work remains fully available at any age — Sarah’s daughter on payroll is the book’s simplest splitting story.
⚠ WARNING
One missed January 30 interest payment taints the prescribed-rate loan permanently — attribution applies for its remaining life. Automate the payment, document the transfer, and keep the borrower’s investment account separate.
