New Canadian AMT Rules Hit Tech Equity
Recent changes to Canada’s Alternative Minimum Tax (AMT) rules could negatively impact tech professionals with high equity income. The new regulations may capture more income than standard rates, especially for those exercising large stock options or making significant charitable donations of appreciated shares, requiring more careful tax planning.
The new Alternative Minimum Tax (AMT) rules, which took effect January 1, 2024, represent the most significant reform to this parallel tax system since its introduction in 1986. The federal AMT rate has been increased from 15% to 20.5%, and while the basic exemption amount was raised substantially from $40,000 to approximately $173,205 for 2024, the tax base itself has been broadened. For tech professionals compensated with equity, the taxable benefit from employee stock options is now fully included in the AMT calculation, a jump from the previous 80% inclusion rate. Similarly, 100% of all capital gains are now included in the AMT base, up from 80% previously, which can subject large gains to a higher effective tax rate than under the regular system. These changes mean that exercising a significant number of stock options could now single-handedly trigger an AMT liability, even if the regular tax calculation would have been lower. The AMT is calculated in parallel to the standard income tax, and the taxpayer is required to pay whichever amount is higher. Any additional tax paid due to the AMT can be carried forward for up to seven years to offset regular tax payable in the future. The treatment of charitable giving, a common tax planning strategy for high-income earners, has also been revised. For donations of publicly traded securities, 30% of the capital gain is now included in the AMT base, whereas it was previously 0%. Furthermore, only 80% of the charitable donation tax credit can be used to reduce the calculated AMT, down from 100% previously.
