The alternative minimum tax (AMT) on individuals was created in 1969 – by the Tax Reform Act of 1969 (P.L. 91-172; 12/30/69). This problematic tax is about to reach its 50th anniversary at the end of the year. With the Tax Cuts and Jobs Act of 2017, the corporate AMT was repealed, it is time to repeal the individual AMT and deal with the reasons why it was enacted in a more equitable and logical manner.
Here is the description from the Joint Committee on Taxation’s Summary of H.R. 13270, The Tax Reform Act of 1969 (8/18/69): “Limit on Tax Preferences.—In those cases where tax preferences are not fully subject to tax, provision is made for a minimum tax on individuals having tax preferences in excess of their taxable in- come. The additional tax in this case is determined by adding to the regular income subject to tax, one-half of the tax preferences but only to the extent they exceed the regular income.”
The JCT report lists reasons for and against the minimum tax, as follows.
