When tax season rolls around, one term that often causes confusion and concern is the Alternative Minimum Tax (AMT). For higher-income earners, understanding the AMT is crucial because it can significantly affect how much you owe the IRS.
Let’s break down what the Alternative Minimum Tax is, how it works, who it impacts, and whether there are ways to avoid it.

What is the alternative minimum tax (AMT)?
The Alternative Minimum Tax (AMT) is a parallel tax system that ensures high-income individuals, corporations, estates, and trusts pay at least a minimum amount of tax. It was created to prevent wealthy taxpayers from using loopholes and deductions to avoid paying little or no tax.
Unlike the regular tax system, which allows numerous deductions, credits, and exemptions, the AMT has its own set of rules. It eliminates many of the deductions allowed under the regular tax system and applies a flat rate once income exceeds certain thresholds.
Who qualifies for the AMT?
Not everyone needs to worry about the AMT. It mainly targets higher-income taxpayers with a lot of deductions. Still, it's a good idea to check each year since your situation might change.
The Tax Cuts and Jobs Act (TCJA) of 2017 increased the AMT exemption amounts and phased-out thresholds, meaning fewer taxpayers are affected than in previous years. However, if you have significant itemized deductions or income from certain sources, you might still fall into the AMT bracket.
What triggers the alternative minimum tax?
The Alternative Minimum Tax (AMT) doesn't kick in at a specific income level but is more likely to affect taxpayers with an adjusted gross income (AGI) over $200,000, especially if they claim substantial deductions. The exact threshold for AMT application can vary depending on your specific income sources and deductions.
Several factors can trigger the AMT, including:
- High state and local tax deductions
- Large number of dependents
- Significant miscellaneous itemized deductions
- Exercising incentive stock options
- High medical expenses
- Large mortgage interest deductions
If you fall into any of these categories, you might need to calculate your taxes under the AMT rules.
To determine whether you owe the AMT and calculate the amount if applicable, you'll need to file Form 6251. Here’s how it works:
- Calculate your Tentative Minimum Tax (TMT): This involves adding back certain deductions and adjustments to your regular taxable income.
- Compare TMT to regular tax liability: If the TMT is higher than your regular tax liability, the difference is the AMT you owe.
Filing Form 6251 is essential to ensure compliance with AMT regulations and helps prevent underpayment of taxes due to AMT requirements. It's important to carefully review this form or consult a tax professional if you're unsure how to fill it out correctly.
How is AMT calculated? What are the AMT exemption amounts?
Calculating the AMT can be a bit tricky since it runs parallel to the regular tax system. Here’s a simplified breakdown of how to calculate the alternative minimum tax with the updated exemption amounts for the tax year 2024:
- Calculate your regular taxable income: Start with your adjusted gross income (AGI) and subtract your itemized deductions or standard deduction.
- Add back AMT preferences and adjustments: Certain deductions allowed in the regular tax system are added back into your income. These include personal exemptions, state and local taxes, and certain miscellaneous itemized deductions.
- Subtract the AMT exemption amount: The AMT exemption is a set amount that reduces your AMT taxable income. For the 2024 tax year, the exemption amounts are $85,700 for individuals and $133,300 for married couples filing jointly. These amounts phase out at higher income levels, meaning the exemption decreases as your income increases.
- Apply the AMT tax rate: The AMT rates are 26% and 28%, and they are applied to the AMT taxable income that exceeds the exemption amount.
- Compare with regular tax liability: If your AMT liability is higher than your regular tax liability, you pay the AMT amount.
Alternative minimum tax example
Let's say you're a single filer with a taxable income of $200,000. You add back $50,000 in state and local taxes and $20,000 from tax-exempt interest, giving you an (AMTI) of $270,000. You subtract the exemption of $85,700, leaving $188,700. The first $220,700 is taxed at 26%, and the rest at 28%.
Regular Taxable Income: $200,000
Add AMT Preferences: $50,000 + $20,000
Total AMT Income: $200,000 + $50,000 + $20,000 = $270,000
Subtract AMT Exemption: $270,000 - $85,700 = $184,300
AMT Tax Rate Application: Since $184,300 is less than the $220,700 threshold, the entire amount is taxed at 26%.
AMT Tax: $184,300 * 26% = $47,918
How to avoid AMT tax?
Depending on your financial situation, avoiding the AMT entirely may not be possible, but you can take actions to minimize its impact:
- Manage your deductions: Since certain deductions trigger the AMT, consider managing how and when you take these deductions. For example, you might spread out large medical expenses over multiple years if possible.
- Monitor stock options: If you have incentive stock options, be mindful of when you exercise them. Spreading them out over multiple years might help.
- Consult a tax professional: A tax advisor can help you navigate the complexities of the AMT and develop strategies to minimize your tax liability.
How does the AMT affect capital gains?
When you sell an investment for more than you paid for it, you might have to pay taxes on the profit. This can happen with things like stocks, bonds, real estate, precious metals, options, and even cryptocurrency.
Capital gains can significantly impact your AMT liability because they increase your overall income. If you negotiated stock options in your salary package, this is something to pay extra attention to.
While the capital gains tax rates remain the same under the AMT, having large capital gains can push your total income into a higher bracket, triggering the AMT. Planning the timing of realizing capital gains can help manage your AMT exposure.
Bottom line
The Alternative Minimum Tax ensures that everyone, especially high-income earners, pays their fair share of taxes. It's essential to understand how it works, who it affects, and how to plan around it. By staying informed and possibly seeking advice from a tax professional, you can navigate the AMT and manage your tax liabilities effectively.
