How to Calculate the New Capital Gains Tax on the Sale of Your Business (Canada 2024)
Over the past few weeks, we’ve received an influx of inquiries from clients concerned about how the newly proposed capital gains inclusion rate increase in Budget 2024 will affect their upcoming business sale. The changes are significant, impacting both asset sales and share sales of small businesses in Canada.
There is no way to avoid the increased tax rate unless you complete an estate or corporate freeze before the June 25, 2024, deadline. Even then, only the value at the date of the freeze benefits from the old rate; all future gains will be taxed at the higher inclusion rate. Additionally, a freeze may not be feasible for transactions already underway.
Below, we provide several sample tax calculations to illustrate the differences between the current 50% inclusion rate and the new 66% inclusion rate, along with the impact of the Lifetime Capital Gains Exemption (LCGE) and the Canadian Entrepreneurs Incentive (CEI).
