Alternative Minimum Tax for High-Income Individuals
The Alternative Minimum Tax (AMT) is a parallel tax calculation that allows fewer deductions, exemptions, and tax credits than under the ordinary income tax rules, and that currently applies a flat 15% tax rate with a standard $40,000 exemption amount instead of the usual progressive rate structure.
The taxpayer pays the AMT or regular tax, whichever is highest. Additional tax paid as a result of the AMT can generally be carried forward for seven years and can be credited against regular tax to the extent regular tax exceeds AMT in those years. The AMT does not apply in the year of death.
Budget 2023 proposes several changes to its calculation.
Broadening the AMT Base
A number of changes are proposed to broaden the AMT base by further limiting tax preferences (i.e., exemptions, deductions, and credits).
Capital Gains and Stock Options
The government proposes to increase the AMT capital gains inclusion rate from 80% to 100%. Capital loss carry forwards and allowable business investment losses would apply at a 50% rate.
It is also proposed that 100% of the benefit associated with employee stock options would be included in the AMT base.
Donations of Publicly Listed Securities
The government proposes to include 30% of capital gains on donations of publicly listed securities in the AMT base, mirroring the AMT treatment of capital gains eligible for the lifetime capital gains exemption. The 30% inclusion would also apply to the full benefit associated with employee stock options to the extent that a deduction is available because the underlying securities are publicly listed securities that have been donated.
Deductions and Expenses
Under the new rules, the AMT base would be broadened by disallowing 50% of the following deductions:
- employment expenses, other than those to earn commission income;
- deductions for Canada Pension Plan, Quebec Pension Plan, and Provincial Parental Insurance Plan contributions;
- disability supports deduction;
- deduction for workers' compensation payments;
- deduction for social assistance payments;
- deduction for Guaranteed Income Supplement and Allowance payments;
- Canadian armed forces personnel and police deduction;
- interest and carrying charges incurred to earn income from property;\
- deduction for limited partnership losses of other years;
- non-capital loss carryovers; and
- Northern residents deductions.
Expenses associated with film property, rental property, resource property, and tax shelters that are limited under the existing AMT rules would continue to be limited in the same manner.
Non-Refundable Credits
Currently, most non-refundable tax credits can be credited against the AMT. The government proposes that only 50% of non-refundable tax credits would be allowed to reduce the AMT, subject to the following exceptions.
The Special Foreign Tax Credit would continue to be allowed in full, and would be based on the new AMT tax rate.
Raising the AMT Exemption
The exemption amount is a deduction available to all individuals (excluding trusts, other than graduated rate estates) that is intended to protect lower and middle-income individuals from the AMT.
The government proposes to increase the exemption from $40,000 to the start of the fourth federal tax bracket. Based on expected indexation for the 2024 taxation year, this would be approximately $173,000. The exemption amount would be indexed annually to inflation.
Increasing the AMT Rate
The government proposes to increase the AMT rate from 15% to 20.5%, corresponding to the rates applicable to the first and second federal income tax brackets, respectively.
The proposed changes would come into force for taxation years that begin after 2023.
