Tax Center: Tax Changes 2003–2018

What is the latest news from Congress about legislation relating to the alternative minimum tax?

The tax reform that took effect in 2018 includes significant changes to the calculation of the alternative minimum tax (AMT) that will result in a reduced likelihood of having to pay the AMT. These changes include much higher AMT income exemption amounts than those in the past and a significant increase in the income point where the AMT phaseout begins. For details on tax reform, see the related FAQ.

The table below summarizes the AMT income exemption amounts, phaseouts, and rate thresholds that apply to income in the 2018 tax year. For details about the AMT calculation, see the related FAQ.
