S.J. Res. 39 is a joint resolution that directs Congress to disapprove an Internal Revenue Service rule concerning the Section 45Y Clean Electricity Production Credit and the Section 48E Clean Electricity Investment Credit; the resolution states that the rule "shall have no force or effect." The targeted regulation appears at 90 Fed.
Reg. 4006 (Jan. 15, 2025).
Why this matters: the resolution, if enacted, would remove an administrative implementation of two clean‑energy tax credits. That outcome can alter tax compliance expectations, interrupt ongoing tax planning and financings built around the IRS interpretation, and shift disputes back into audit and litigation channels rather than regulatory compliance paths.
At a Glance
What It Does
The joint resolution invokes the Congressional Review Act (chapter 8 of title 5, U.S. Code) to nullify an IRS rule addressing Sections 45Y and 48E. It declares the specific published rule to be without legal force.
Who It Affects
Project developers, tax‑equity investors, utilities, and tax advisors who rely on IRS guidance for credit eligibility and structuring would face immediate uncertainty. The IRS and Treasury would lose the regulatory instrument created by that rule.
Why It Matters
Nullification under the CRA both removes the current rule and, subject to CRA constraints, blocks the agency from issuing a substantially similar rule without new congressional authorization—shifting how the credits are administered and interpreted in practice.

What This Bill Actually Does
The resolution targets a particular IRS regulation that interprets and implements two clean‑electricity tax incentives created by Congress: the production credit in Section 45Y and the investment credit in Section 48E. Rather than amend the statutes, the joint resolution exercises Congress’s statutory review power to overturn an agency rule that interprets those statutory provisions.
The text of S.J. Res. 39 identifies the rule by Federal Register citation (90 Fed.
Reg. 4006, Jan. 15, 2025) and states that the rule "shall have no force or effect."
Legal mechanics matter more than the bill’s three lines. Under the Congressional Review Act (chapter 8 of title 5), a successful disapproval resolution voids the targeted rule and constrains the agency’s ability to repromulgate a substantially similar rule without explicit congressional authorization.
The resolution itself does not change the underlying tax code; it only removes this particular regulatory interpretation and the operational certainty that came with it. Taxpayers remain subject to the statute as written and to any other IRS guidance or enforcement action consistent with the statute.Practically, the disappearance of the rule means two immediate consequences for market participants.
First, parties that structured transactions relying on the rule’s definitions, safe harbors, or procedures may lose the administrative assurance they believed they had and face greater audit risk. Second, the financing market may pause or re‑price deals while lawyers, accountants, underwriters, and lenders reassess legal interpretations and the fallback positions the IRS and taxpayers will now adopt.
Agencies can respond with alternative, non‑rule guidance (letters, notices, or private rulings), but those forms have different legal status and do not carry the same permanence as a rule.
The Five Things You Need to Know
The resolution identifies the targeted regulation as appearing at 90 Fed. Reg. 4006, published January 15, 2025.
It expressly concerns IRS interpretations of two statutory credits: Section 45Y (Clean Electricity Production Credit) and Section 48E (Clean Electricity Investment Credit).
The text directs that the named rule "shall have no force or effect," which is the operative invalidation language in the joint resolution.
S.J. Res. 39 is framed as a Congressional Review Act disapproval under chapter 8 of title 5, which carries a separate restriction on reissuing substantially similar rules.
Senator Mike Lee introduced the joint resolution on March 26, 2025; it was read twice and referred to the Senate Committee on Finance.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Identification of the rule and legislative vehicle
The opening lines state the bill is a joint resolution disapproving an IRS rule, and they provide the Federal Register citation. This establishes exactly which agency action the resolution targets; that specificity matters because the Congressional Review Act operates against particular rulemaking records rather than abstract agency policies.
Congressional disapproval and nullification
The single operative clause declares that "Congress disapproves the rule" and that the rule "shall have no force or effect." Practically, that language is the statutory instrument of invalidation—the resolution does not attempt to rewrite tax law, it removes the agency's published regulatory interpretation.
Use of the Congressional Review Act (chapter 8 of title 5)
By invoking chapter 8 of title 5, the resolution follows the CRA framework: a joint resolution of disapproval removes the rule and triggers the CRA's bar on reissuing a substantially similar rule without new congressional authorization. That bar is a consequential, often overlooked feature: it limits the agency’s regulatory pathways going forward and channels dispute resolution back to litigation or fresh statutory change.
Sponsor and committee referral
The bill identifies Sen. Mike Lee as sponsor and records referral to the Senate Committee on Finance. That procedural detail matters for practitioners tracking which committee will consider floor action and which staff and committee reports will shape any amendments or debate.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- Companies and taxpayers who opposed the IRS rule: they gain the immediate removal of an administrative interpretation they viewed as unfavorable, reducing the risk that the rule’s requirements will be enforced against past transactions that lack the rule’s compliance features.
- Taxpayers who prefer statutory ambiguity resolved by litigation rather than new administrative requirements: disapproval pushes disputes into audits and courts instead of rule‑based compliance regimes.
- Political actors and advocacy groups that favor stronger Congressional oversight of administrative agencies: they gain a concrete example of Congress overturning an agency regulation and constraining future rulemaking.
Who Bears the Cost
- Project developers, lenders, and tax‑equity investors relying on the rule for deal structuring: they face heightened legal uncertainty, potential delays in financings, and the need to renegotiate transactions or obtain additional protections.
- The Internal Revenue Service and Treasury Department: they lose a formal regulatory tool implementing complex statutory credits and face constraints on issuing a substantially similar rule in the future.
- Markets and intermediaries (underwriters, attorneys, accountants): they bear increased compliance and due‑diligence costs as standard assumptions tied to the rule vanish and bespoke legal analysis becomes necessary.
Key Issues
The Core Tension
The bill pits two legitimate goals against each other: preventing perceived agency overreach in implementing complex tax incentives versus preserving clear, durable administrative rules that provide certainty for large, capital‑intensive energy projects. Knocking out the rule protects against an unwanted interpretation but also removes the predictability these credits were meant to deliver to investors and developers.
Two implementation tensions deserve attention. First, nullifying a rule under the CRA does not alter the statutory text of Sections 45Y or 48E; it simply removes one administrative interpretation.
That means the IRS can still enforce the statute through audits, litigation, or alternative guidance formats that fall outside the CRA’s immediate scope. Parties that gain short‑term relief from the rule’s invalidation may face downstream uncertainty because the underlying statutory ambiguities remain.
Second, the CRA’s prohibition on reissuing a "substantially similar" rule creates a legal gray zone. Agencies may try to achieve the same substantive ends through different regulatory drafting or rely on non‑rule guidance (notices, private letter rulings, revenue procedures), but those instruments have different legal weight and are more vulnerable to challenge.
The bill therefore trades a standing regulatory framework for a more fragmented enforcement landscape—reducing one form of administrative burden while increasing litigation and transactional risk.
