Alternative Minimum Tax Repealed - Corporate

Under pre-Act law, the corporate alternative minimum tax (AMT) is 20%, with an exemption amount of up to $40,000. Corporations with average gross receipts of less than $7.5 million for the preceding three tax years are exempt from the AMT. The exemption amount phases out starting at $150,000 of alternative minimum taxable income.

New law. For tax years beginning after Dec. 31, 2017, the corporate AMT is repealed.

For a corporation, the AMT credit is allowed to offset the regular tax liability for any tax year. For tax years beginning after 2017 and before 2022, the AMT credit is refundable in an amount equal to 50% (100% for tax years beginning in 2021) of the excess of the minimum tax credit for the tax year over the amount of the credit allowable for the year against regular tax liability. Accordingly, the full amount of the minimum tax credit will be allowed in tax years beginning before 2022.
