The Tax Cuts & Jobs Act, which took effect in 2018, made significant changes to factors in the calculation of the alternative minimum tax (AMT) that will generally reduce the 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.
