What is the Alternative Minimum Tax?
The Alternative Minimum Tax (AMT) is a separate tax system designed to ensure that high-income taxpayers pay at least a minimum amount of tax, regardless of deductions or credits they may claim. It operates parallel to the regular income tax system and requires taxpayers to calculate their tax liability under both systems, paying the higher of the two amounts.
How AMT Works
- Taxpayers must complete Form 6251, Alternative Minimum Tax—Individuals, to determine if they owe AMT.
- AMT eliminates or limits many deductions and credits allowed under the regular tax system, such as state and local tax deductions, miscellaneous itemized deductions, and certain personal exemptions.
- It applies to individuals, estates, and trusts, and is calculated using a different set of rules and tax rates.
When Does AMT Apply?
AMT typically affects taxpayers with high incomes and those who claim many itemized deductions. The AMT exemption amount phases out as income increases, which can trigger AMT liability for taxpayers who would otherwise be in lower tax brackets.
