In a move to ease the tax administration challenges faced by corporations, the IRS has issued Notice 2024-33, providing a limited waiver for the underpayment of estimated taxes, particularly focusing on the Corporate Alternative Minimum Tax (CAMT) liabilities. This update is crucial for corporate tax planning, especially for businesses navigating the complexities introduced by the Inflation Reduction Act of 2022. Here’s what corporations need to understand about the waiver and how it applies to their tax filings in 2024.

Overview of the IRS Notice

The waiver provided by the IRS under Section 6655 of the Internal Revenue Code is specifically designed to address the underpayment of estimated income taxes by corporations to the extent that the underpayment is attributable to the corporation’s CAMT liability under Section 55. This relief is significant given the recent amendments to CAMT regulations, which now include calculations based on “adjusted financial statement income” (AFSI) for taxable years beginning after December 31, 2022.

Scope and Applicability

The relief outlined in the notice applies only to the installment of estimated income tax that is due on or before April 15, 2024, or for fiscal year taxpayers beginning in February 2024, by May 15, 2024. It specifically waives the addition to tax for any underpayment linked directly to the portion of CAMT liability due in that installment. For installments due after these dates, normal rules under Section 6655 apply, and the waiver does not extend to underpayments related to other tax code provisions.

Conditions for the Waiver

For a corporation to qualify for this waiver, the underpayment must solely be due to the CAMT obligations calculated under the new rules. This waiver is part of the IRS’s efforts to provide relief while regulations and corporate understanding of the new CAMT framework continue to evolve. It reflects the complexities of calculating taxes based on the new AFSI criteria and the recognition of potential difficulties corporations may encounter.

Action Required by Corporations

Affected corporations should be proactive:

  • Review the CAMT Liability: Corporations need to carefully calculate their CAMT liability to understand the portion attributable to the waived addition to tax.
  • File Form 2220: Despite the waiver, corporations must still file Form 2220 with their federal income tax returns to clarify their estimated tax calculations and ensure they are not penalized for underpayment related to non-CAMT liabilities.
  • Documentation and Compliance: It’s crucial to maintain detailed documentation that supports the computation of the CAMT and its impact on estimated tax payments to leverage this waiver effectively.


The IRS’s waiver for the underpayment of estimated taxes related to CAMT liabilities provides much-needed relief for corporations adjusting to the new tax calculations introduced by the Inflation Reduction Act. By understanding and properly applying this waiver, corporations can avoid unnecessary penalties while adapting to the evolving tax landscape. Always consider consulting with a tax professional to ensure full compliance and optimal tax strategy planning.
