TOSI is an acronym that stands for "Tax on Split Income" and refers to a Canadian tax rule designed to prevent income splitting among family members in order to mitigate tax advantages. TOSI aims to ensure that individuals pay taxes on income they have earned personally, rather than diverting it to family members who may be in a lower tax bracket. This rule was introduced to discourage individuals from using businesses, corporations, or other entities to distribute their income to family members who are not actively involved in the business.
Under TOSI, any income received by a specified individual, which includes individuals under the age of 18, is subject to additional taxes if their involvement in the business is not considered "reasonable." Reasonable involvement typically refers to active participation in the business, providing meaningful contributions, or investing a significant amount of capital.
The application of TOSI involves determining whether the income received by the individual constitutes a reasonable return on their contributions or efforts. This determination is made by assessing various factors such as labor contributed, capital invested, risks assumed, and previous payments made to the individual in similar circumstances.
TOSI helps to ensure fairness in taxation by preventing high-income individuals from distributing their earnings to family members, who may fall into lower-income tax brackets, thereby reducing their overall tax burden.
