Summary

Disapproves and nullifies the IRS interim guidance titled "Interim Guidance Simplifying Application of the Corporate Alternative Minimum Tax to Partnerships" (IRS Notice 2025–28), stating that the rule "shall have no force or effect." The resolution removes the specific IRS guidance treating how the corporate alternative minimum tax (CAMT) applies to partnerships, leaving the prior legal and administrative framework in place until further action.

• Declares that IRS Notice 2025–28 (interim guidance on CAMT for partnerships) has no force or effect.
• Blocks a specific piece of IRS administrative guidance rather than changing statutory tax law.
• Leaves tax treatment of partnerships under the corporate AMT governed by preexisting law, regulations, and IRS practice until replaced.
• Directly affects partnerships, partners, corporate taxpayers, and tax preparers who relied on or would rely on the guidance.
• Does not authorize spending, change tax rates, or create new programs.
• Creates regulatory and compliance uncertainty until the IRS issues new guidance or Congress acts further.
• Limits the IRS's ability to enforce or apply the nullified notice in audits or determinations.
