A coalition of trade organizations that includes The Real Estate Roundtable asked the IRS to issue regulatory guidance clarifying that unrealized gains and losses are not subject to tax under the new corporate alternative minimum tax (CAMT). Enacted under the Inflation Reduction Act of 2022, CAMT levies a 15% minimum tax on the adjusted financial statement income (book income) of certain large corporate taxpayers.  

  • Starting this year, the CAMT applies to firms with an average of $1 billion or more in profits in any three-year period and to foreign-parented U.S. firms with profits of over $100 million if the aggregated foreign group has over $1 billion in profits. Congress expressly exempted REITs from the tax. (Congressional Research Service, Jan. 19, 2023)

  • The coalition’s comments respond to a Dec. 27, 2022 IRS Notice (2023-7) that states Treasury may issue future guidance intended “to help avoid substantial unintended adverse consequences” from the interaction of mark-to-market accounting and the CAMT. Congress granted the Treasury Secretary substantial regulatory authority to implement the new tax. (Debevoise & Plimpton, Jan. 3 and Gibson Dunn, Jan. 6)
