IRS grants penalty relief for corporations that did not pay estimated tax related to the new corporate alternative minimum tax

WASHINGTON — The Department of Treasury and the Internal Revenue Service today issued Notice 2023-42, which will grant penalty relief for corporations that did not pay estimated tax in connection with the new corporate alternative minimum tax (CAMT).

The Inflation Reduction Act created the CAMT, which imposes a 15% minimum tax on the adjusted financial statement income of large corporations for taxable years beginning after Dec. 31, 2022. CAMT generally applies to large corporations with average annual adjusted financial statement income exceeding $1 billion.

Considering the challenges associated with determining the amount of a corporation’s CAMT liability and whether a corporation is an applicable corporation subject to the CAMT, the IRS will waive the penalty for a corporation’s failure to pay estimated income tax with respect to its CAMT for a taxable year that begins after Dec. 31, 2022, and before Jan. 1, 2024.
