What the 2024 AMT Changes Mean for You

  • Capital Gains: Under regular tax, only 50% (or 66.7% over $250K) of gains are taxable. Under AMT, 100% is included in your adjusted minimum income base — meaning large one-time gains like selling a cottage or business can trigger significant AMT.
  • Charitable Donation Credit: Under regular tax, the donation tax credit reduces your full tax owing. Under AMT, only 80.5% of the credit is permitted. Large donation strategies (donating flow-through shares) are most affected.
  • Carry-Forward Credit: Any AMT you pay can be carried forward for up to 7 years and used to offset regular federal tax in future years when your income is lower.
  • Trusts Now Subject to AMT: Since 2024, graduated rate trusts and family trusts are also subject to AMT at the 20.5% rate — previously only individuals were covered.
