This blog post is a follow-up to part 1, published yesterday.
Example 1: Impact of Increased AMT Rate on Capital Gains
Scenario: A taxpayer has a capital gain of $2 million in 2024.
Under Current AMT Rules (2023):
- AMT Rate: 15%
- Inclusion Rate for Capital Gains: 80%
- AMT Base: $2,000,000 * 80% = $1,600,000
- AMT Calculation: $1,600,000 * 15% = $240,000
Under New AMT Rules (2024):
- AMT Rate: 20.5%
- Inclusion Rate for Capital Gains: 100%
- AMT Base: $2,000,000 * 100% = $2,000,000
- AMT Calculation: $2,000,000 * 20.5% = $410,000
Increase in AMT Liability:
- Current AMT: $240,000
- New AMT: $410,000
- Increase: $410,000 – $240,000 = $170,000
Example 2: Impact on Deductions
Scenario: A taxpayer has $500,000 in carrying charges and other deductions.
Under Current AMT Rules (2023):
- Deduction Value: $500,000
- AMT Base Reduction: $500,000 * 100% = $500,000
Under New AMT Rules (2024):
- Deduction Value: $500,000
- AMT Base Reduction: $500,000 * 50% = $250,000
Decrease in Deduction Value:
- Current Deduction Value: $500,000
- New Deduction Value: $250,000
- Decrease: $500,000 – $250,000 = $250,000
Example 3: Impact of Donation Tax Credit
Scenario: A taxpayer donates $1 million to charity.
Under Current AMT Rules (2023):
- Donation Tax Credit: 33% of $1,000,000 = $330,000
- AMT Reduction: $330,000
Under New AMT Rules (2024):
- Donation Tax Credit (AMT): 50% of 33% = 16.5%
- AMT Reduction: $1,000,000 * 16.5% = $165,000
Decrease in Donation Tax Credit Value:
- Current Credit Value: $330,000
- New Credit Value: $165,000
- Decrease: $330,000 – $165,000 = $165,000
Example 4: Combining Capital Gains and Donations
Scenario: A taxpayer has $1 million in capital gains and makes a $1 million donation.
Current Rules (2023):
- Capital Gains Tax: $1,000,000 * 15% (AMT Rate) = $150,000
- Donation Credit: $1,000,000 * 33% = $330,000
- Net AMT Impact: $150,000 (tax) – $330,000 (credit) = -$180,000 (No AMT)
New Rules (2024):
- Capital Gains Tax: $1,000,000 * 20.5% = $205,000
- Donation Credit: $1,000,000 * 16.5% = $165,000
- Net AMT Impact: $205,000 (tax) – $165,000 (credit) = $40,000 (AMT Payable)
Conclusion
These calculations show how the changes to AMT rates, inclusion rates for capital gains, and the value of deductions and credits can significantly impact high-income earners. The increased AMT rate and the reduced effectiveness of deductions and credits mean that many taxpayers will face a higher AMT liability starting in 2024.
Financial advisors can help clients navigate the new AMT landscape and minimize their tax liabilities by understanding these changes and planning accordingly.
