IRS Provides More Guidance on New Corporate AMT

The corporate AMT imposes a 15% minimum tax on the adjusted financial statement income of large corporations.

The IRS and the Treasury Department on Friday released Notice 2024-10, which provides additional interim guidance on the new corporate alternative minimum tax.

The corporate AMT was created by last year’s Inflation Reduction Act and imposes a 15% minimum tax on the adjusted financial statement income (AFSI) of large corporations for taxable years beginning after Dec. 31, 2022. The corporate AMT generally applies to large corporations with average annual financial statement income exceeding $1 billion.

The IRS previously issued Notice 2023-64 last September, guidance aimed at helping corporations determine whether the new corporate AMT applies to them and how to compute the new tax. The guidance issued in September clarifies and supplements Notice 2023-07 and Notice 2023-20 issued earlier this year. Treasury and IRS anticipate that forthcoming proposed regulations will be consistent with this interim guidance.
