In 2018, existing Tax on Split Income (“TOSI”) rules were significantly broadened. Today, TOSI makes it much more difficult – if not impossible – to save tax by splitting the income of a family business with family members. This course will cover the fundamentals of the “expanded” TOSI rules. Topics will include: • Tax implications of income being subject to TOSI • What is TOSI and why does it exist? • Background & history o Kiddie Tax – 1999 to 2017 o TOSI – since 2018 • Detailed review of the expanded TOSI rules • Application of the expanded TOSI rules o Examples • Practical considerations
