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 "Beginning of Construction Requirements for Purposes of the Termination of Clean Electricity Production Credits and Clean Electricity Investment Credits for Applicable Wind and Solar Facilities".

Summary of the Joint Resolution

This joint resolution is an attempt by Congress to cancel ("disapprove") a rule issued by the Internal Revenue Service (IRS) that sets standards for when wind and solar energy projects qualify for certain federal tax credits. Specifically, the IRS rule defines what it means for a wind or solar facility to have "begun construction" — a key threshold that determines whether a project can still claim Clean Electricity Production Credits or Clean Electricity Investment Credits before those credits phase out. Under the Congressional Review Act, Congress has the power to vote to overturn federal agency rules it disagrees with.

If this resolution had passed, it would have thrown out the IRS rule entirely, removing the guidance that energy developers rely on to know whether their projects qualify for these tax credits. This would primarily affect businesses and developers building wind and solar energy facilities, as well as investors and communities connected to those projects. Without the IRS rule in place, there could be significant uncertainty about which projects are eligible for tax incentives under current law.

The resolution did not advance in the Senate. A vote on whether to simply begin debating the measure failed 47–53, meaning the full Senate never took a final vote on whether to actually cancel the IRS rule. As a result, the IRS rule remains in effect. The resolution had been pushed out of the Senate Finance Committee through a procedural petition rather than through a standard committee review process.
