The Alternative Minimum Tax (AMT) for 2024: What High-Income Taxpayers Need to Know

The alternative minimum tax (AMT) is a separate tax system that runs parallel to the regular income tax system. It’s designed to ensure that high-income taxpayers pay a minimum amount of tax, regardless of certain deductions and exemptions they might utilize under the regular tax rules. This guide provides an overview of the AMT for the 2024 tax year, including its calculation, exemptions, rates, and who is most likely to be affected.

Understanding the AMT

The AMT primarily impacts individuals (who use Form 6251) and corporations (who use Form 4626) with high incomes. It limits certain deductions and exemptions available under the regular tax rules, ensuring that these taxpayers contribute their fair share. Essentially, the AMT sets a floor for income tax, preventing excessive reduction of tax liability through deductions or exemptions.

Calculating the AMT for 2024

Calculating the AMT involves several steps:

1. Calculate Alternative Minimum Taxable Income (AMTI):

Begin with your regular taxable income and make adjustments. This includes adding back certain deductions allowed under the regular tax system, such as:

• Standard deduction or certain itemized deductions: state and local taxes, medical expenses, etc.
• Personal exemptions
• Certain miscellaneous itemized deductions

You might also need to add back or deduct other items depending on your specific tax situation, such as investment interest, net operating losses, and tax refunds. Refer to Form 6251 and the IRS instructions for a comprehensive list.

2. Subtract the AMT Exemption:

Subtract the AMT exemption amount from your AMTI. For 2024, the exemption is:

• $85,700 for single filers
• $133,300 for married couples filing jointly
• $66,650 for married individuals filing separately

This exemption begins to phase out for higher incomes, starting at:

• $609,350 for single filers
• $1,218,700 for married couples filing jointly
• $609,350 for married individuals filing separately

It’s important to note that the exemption phases out at a rate of 25 cents for every dollar earned above the threshold.

3. Calculate the Tentative Minimum Tax (TMT):

Multiply the remaining amount (after subtracting the exemption) by the appropriate AMT rate. For 2024, the AMT rates are:

• 26% for income up to $232,600
• 28% for income above $232,600

The same $232,600 threshold applies to both single filers and married couples filing jointly. For married individuals filing separately, the threshold is $116,300.

4. Subtract the Regular Tax:

Subtract your regular income tax liability from the TMT. If the result is positive, this is your AMT liability. If the result is zero or negative, you do not owe any AMT.

Example:

Let’s say you’re a single filer with an AMTI of $300,000.

1. Exemption: You would subtract the $85,700 exemption, leaving $214,300.
2. Phase-out: Since your AMTI is above the $609,350 phase-out threshold, part of your exemption would be phased out.
3. TMT: The first $232,600 of your remaining income would be taxed at 26%, and the amount above that would be taxed at 28%.
4. AMT Liability: You would then subtract your regular tax liability from this amount to determine your final AMT liability.

Who is Affected by the AMT?

The AMT primarily affects high-income taxpayers who utilize significant deductions and exemptions. Those with a large number of tax preference items (like incentive stock options) may also be subject to AMT. Taxpayers with simpler tax situations and lower incomes are less likely to be impacted.

Investment Considerations and the AMT

Certain investments can trigger the AMT, even if they are taxed favorably under the regular tax system. For example:

Incentive Stock Options (ISOs):

When you exercise ISOs, the difference between the market price and your exercise price (the “bargain element”) is considered a tax preference item for AMT purposes, even though you might not realize a taxable gain for regular tax purposes until you sell the stock. This can lead to an AMT liability in the year of exercise, even if you haven’t sold the shares and recognized any profit.

Comparing Regular Tax and AMT Deductions

The AMT has different rules for deductions than the regular tax system. Here’s a comparison of some common deductions:

AMT Credit Carryforward

If you pay AMT in one year, you may be able to claim an AMT credit in future years to offset your regular tax liability. This can help to alleviate the impact of the AMT over time. Essentially, it allows you to recoup some or all of the AMT you paid when your regular tax liability exceeds your AMT liability in a later year.
