Although Congress, as part of the recent tax reform, promised to do away with the alternative minimum tax (AMT), it only did so for C corporations; as a result, the AMT still applies to individuals.

Congress originally developed the AMT in 1969 as a means to prevent high-income individuals from using tax shelters to reduce their taxes. For the AMT, federal income tax is calculated without certain deductions and tax preferences. This tax applies if it is greater than the regularly computed income tax. Although it has since been indexed to inflation, the AMT at one point began to apply to middle-income taxpayers, who are not the intended targets of this punitive tax.

The AMT computation includes a tax-exempt amount, but this amount begins to phase out for taxpayers whose adjusted gross income (AGI) exceeds a certain threshold (depending on their filing status). Although the tax reform did not eliminate the AMT, it did mute that tax considerably by increasing the AMT exemptions and by substantially raising the exemption-phaseout thresholds, as illustrated below. The exemptions and AGI phaseout thresholds will be inflation-adjusted in future years.
