The biggest and most expensive mistake Canadian business owners make is waiting until the fiscal year-end to have their first conversation with an accountant about corporate tax planning. By that point, most opportunities to structure transactions, time income and expenses, optimize compensation, and implement tax-saving strategies have already passed. Strategic tax planning sessions throughout the year help business owners decide the optimal salary versus dividend mix to minimize personal tax obligations while keeping the corporation tax-efficient based on constantly changing income levels and personal situations.
