AMT income exemption

This is part of the AMT calculation. After your AMT income (AMTI) is determined, it is reduced by an exemption amount to reach your amount of taxable AMTI in the complex AMT calculation. This AMT exemption replaces the personal exemption and standard deduction from the regular-tax system.

  • The AMT income exemption amounts for the 2018 tax year are $70,300 for single filers and $109,400 for married joint filers.
  • The AMT income exemption amounts for the 2019 tax year are $71,700 for single filers and $111,700 for married joint filers.

This AMTI exemption amount is phased out for high-income individuals by 25 cents for every dollar of AMTI over specified thresholds.

  • 2018 tax year: For single filers, the phaseout range starts at $500,000 of AMT income. For married joint filers, the phaseout range starts at $1,000,000 of AMT income. The exemption is fully phased out when AMTI equals or exceeds $781,200 for single filers and $1,437,600 for joint filers.
  • 2019 tax year: For single filers, the phaseout range starts at $510,300 of AMT income. For married joint filers, the phaseout range starts at $1,020,600 of AMT income. The exemption is fully phased out when AMTI equals or exceeds $797,100 for single filers and $1,467,400 for joint filers.

The net amount of AMTI is multiplied by the AMT rate to obtain the amount of AMT you owe.

  • 2018 tax year: For unmarried single filers and married joint filers alike, the AMT rate is 26% up to $191,500 and 28% for greater amounts of AMTI. For married people filing separate returns, the threshold is $95,750.
  • 2019 tax year: For unmarried single filers and married joint filers alike, the AMT rate is 26% up to $194,800 and 28% for greater amounts of AMTI. For married people filing separate returns, the threshold is $97,400.
