📊 What Is the Alternative Minimum Tax (AMT)?

The Alternative Minimum Tax is a separate tax system designed to ensure that high-income taxpayers pay at least a minimum amount of tax. AMT limits the benefits of certain deductions and credits allowed under the regular tax system.

  • Applies to individuals, corporations, estates, and trusts
  • Calculated using AMT income, adding back certain preferences and adjustments
  • Designed to prevent taxpayers from avoiding tax entirely through deductions

📐 How to Use the Finance Alternative Minimum Tax Calculator

Step-by-Step Calculation

  • Determine your AMT income: add back deductions and exemptions disallowed under AMT
  • Subtract AMT exemptions to get taxable AMT income
  • Apply the AMT tax rate (typically 26%–28% for individuals)
  • Compare with regular tax; pay the higher amount

Example: Individual AMT Calculation

Suppose:

  • Regular taxable income: $200,000
  • Deductions disallowed under AMT: $30,000
  • AMT exemption: $75,900

AMT income = $200,000 + $30,000 − $75,900 = $154,100
AMT liability = 26% × $154,100 = $40,066
If regular tax = $35,000 → pay AMT = $40,066
