The AMT tax brackets have also been adjusted. For 2018, the 26% tax rate applies to the first $175,800 ($87,500 if married filing separately) of taxable excess over the exemption amount and the 28% tax rate applies to the taxable excess over the first $175,800 ($87,500 if married filing separately).
For corporations, the alternative minimum tax has been repealed for the taxable years starting after December 31, 2017 (or tax year 2018). Companies that have an alternative minimum tax credit for AMT paid in prior years will be allowed to use the credit, subject to limits, in full before 2022 using Form 8827. The credit is refundable during the period from 2018 to 2021.
Note: With the repeal of corporation AMT, screen 4626 in the 1120 data entry and the Form 4626 are not available starting in Drake18.
