Definition
The Alternative Minimum Tax (AMT) is a parallel tax system in the United States designed to ensure that high-income taxpayers, including corporations and noncorporate entities, pay a minimum level of tax. The AMT operates with a separate set of rules and rates compared to the regular income tax and aims to limit certain deductions and credits to prevent excessive tax avoidance.
Key Components
- Tax Rates: The AMT applies a 26% or 28% rate to individual taxpayers and a 20% rate to certain corporations.
- AMT Income: Taxable income under AMT is termed Alternative Minimum Taxable Income (AMTI), which is computed by adjusting regular taxable income to include numerous tax preference items and adjustments.
- AMT Calculation: If the AMT exceeds the taxpayer’s regular income tax calculated under standard tax rules, the taxpayer must pay the AMT amount.
Examples
- Example 1: An individual with a high level of income and significant deductions, such as large mortgage interest payments and state taxes, may find that while their regular tax liability is low, they owe more under the AMT.
- Example 2: A corporation with numerous tax deductions and credits might still incur an AMT liability despite having minimized its regular taxable income.
