Treasury Releases Long-Awaited Proposed Regulations on the Corporate Alternative Minimum Tax

Congress granted the Treasury and the IRS a substantial amount of regulatory authority with respect to the CAMT in the IRA.  This comprehensive package of Proposed Regulations provides almost 200 pages of rules to implement the extraordinarily complex CAMT regime and expands upon and modifies guidance previously issued under Notice 2023-07, Notice 2023-20, Notice 2023-64, and Notice 2024-10.  The Proposed Regulations include guidance with respect to AFSI adjustments relating to taxable year differences, foreign corporations, partnerships, effectively connected income, foreign income taxes, certain income tax credits, depreciation, corporate reorganizations, net operating losses, and troubled companies.  Our prior coverage of the CAMT can be found here, our prior coverage of the IRA can be found here and here, and further coverage and details can be found here.

In general, certain sections of the Proposed Regulations are proposed to apply to tax years ending after September 13, 2024, while other sections of the Proposed Regulations are proposed to apply to tax years ending after the date the Proposed Regulations are finalized.  Accordingly, while taxpayers generally should not need to amend their 2023 tax returns, certain portions of the Proposed Regulations will retroactively capture 2024 transactions that occurred prior to the issuance of the Proposed Regulations.  Taxpayers may generally rely upon the Proposed Regulations for taxable years ending prior to the date the Proposed Regulations are finalized provided that certain consistency and other requirements are satisfied.  The Treasury has requested comments on the Proposed Regulations by December 12, 2024, and a hearing is scheduled for January 16, 2025.  The IRS also issued Notice 2024-66 in connection with the Proposed Regulations, which provides penalty relief for corporations that fail to pay estimated taxes with respect to CAMT liabilities for tax years that begin after December 31, 2023, and before January 1, 2025.

While the Proposed Regulations provide much needed guidance for taxpayers, the interpretation and analysis of these highly complex rules will surely present challenges as taxpayers begin to apply these proposed rules to their particular facts and circumstances.  Stay tuned for additional analysis and insight with respect to the CAMT in light of the issuance of these Proposed Regulations.
