TOSI (split income tax)

The TOSI (Tax on Split Income) is a rule that levies the highest tax rate on money, especially dividends (a share of a company's profits paid to its owners), that an entrepreneur pays to a relative who is not actively involved in the business. It has been in effect since 2018.

Brief

Applies to dividends (shares of a company's profits) and certain income paid to a close relative
The money is taxed at the highest rate, regardless of the actual income of the person receiving it.
Main exit strategy: the relative actually works in the company, at least 20 hours per week
Other exceptions: the entrepreneur's spouse is 65 years of age or older, or a close relative holds "excluded shares" (a significant share of a common company, at age 25 and older)
Quand le TOSI s'applique au Québec, l'argent est frappé au taux marginal le plus élevé, environ 53,3 % en 2026 (fédéral et provincial combinés)

Why does this matter?

Imaginez un restaurateur qui verse 40 000 $ de dividendes (une part des profits) à son fils étudiant, qui ne met jamais les pieds au restaurant, juste pour profiter du faible impôt de l'étudiant. Avant 2018, c'était permis. Le TOSI a fermé cette porte : ce même dividende serait aujourd'hui imposé au taux le plus fort, parfois plus de 50 % (environ 53,3 % au Québec en 2026), entre les mains du fils. Il reste des exceptions légitimes, surtout quand le proche travaille pour vrai dans l'entreprise. Le partage de revenu encadré passe plutôt par une fiducie familiale, par l'exonération des gains en capital (ECGC) partagée entre proches, ou par un gel successoral bien monté. Avant de verser un dividende à un membre de votre famille, faites-en vérifier l'admissibilité auprès de l'ARC (formulaire T1206) : l'erreur coûte cher.

Frequently asked questions

What is TOSI, in one sentence?

This rule prevents an entrepreneur from "shifting" their income to a relative who is not very active in the business simply to pay less tax. When this rule applies, the money paid to the relative (often a dividend, i.e., a share of the profits) is taxed at the highest rate, without any tax benefits.

What are the main exceptions?

The following are exempt: a close relative who works an average of at least 20 hours per week in the business (during the year or the last five years); someone who holds "excluded shares" (at least 10% of the voting rights and value of a non-professional corporation, aged 25 and over); and the spouse of a business owner aged 65 or over. In these cases, the normal rate applies.

Is it still possible to share income within your family?

Yes, but within a framework: a reasonable salary for real work, the exceptions of the TOSI (Tax-Free Social Security Scheme), an RRSP (Retirement Savings Account) and a TFSA (Tax-Free Savings Account) in each person's name remain legitimate options.
