A joint resolution providing for congressional disapproval under chapter 8 of title 5, United States Code, of the rule submitted by the Internal Revenue Service relating to "Interim Guidance Simplifying Application of the Corporate Alternative Minimum Tax to Partnerships".

This binding joint resolution would disapprove an Internal Revenue Service rule regarding how the corporate alternative minimum tax applies to partnerships. The rule being challenged is titled 'Interim Guidance Simplifying Application of the Corporate Alternative Minimum Tax to Partnerships' and was issued by the IRS as administrative guidance.

If enacted, this resolution would use the Congressional Review Act process to invalidate the IRS guidance. This means the tax simplification rule would be overturned, and the IRS would be prohibited from issuing substantially similar guidance without explicit Congressional approval. The practical effect would be that partnerships would continue operating under previous tax rules rather than the simplified guidance the IRS had provided.

The resolution has passed committee review and is eligible for a floor vote in the Senate. However, a motion to proceed to consideration of the measure was rejected in February 2026 by a vote of 47-51, meaning the full Senate has not yet voted on the resolution itself. The bill would require approval from both chambers and the President to become law, though as a joint resolution under the Congressional Review Act, the procedural requirements differ from standard legislation.
