As a result of the new income splitting legislation released on December 13, 2017 , 2017 is the last year for many taxpayers in which dividends could be “sprinkled” to adult family members without attracting tax on split income (“TOSI”). As a result of the new rules, income sprinkling using dividends will likely attract more attention from the Canada Revenue Agency’s (“CRA”) audit department going forward. Therefore, it is important to properly document dividends paid in 2017 and subsequent years.
