If you are researching solar right now, you have almost certainly encountered conflicting information about the federal residential tax credit — whether it is 26% or 30%, whether it ends in 2025 or 2032, and whether the recent budget bill changes anything. That confusion is not unfounded. The credit is in genuine legislative flux as of mid-2025, and the stakes for a purchase decision are significant. This article explains what current law says, what the House-passed reconciliation bill would do if enacted, and how to think about timing without guessing at outcomes that have not been decided.
A note on the limits of this article: Tax laws are complex, and the legislative situation described here was accurate as of late May 2025. Laws can change quickly. Nothing here constitutes tax advice. Consult a qualified tax professional — ideally a CPA or enrolled agent with experience in energy credits — before making any decision that relies on a specific tax outcome.
What the Law Currently Says About the Residential Solar Credit
The federal residential clean energy credit is codified in Section 25D of the Internal Revenue Code. The Inflation Reduction Act (IRA), signed into law in August 2022, extended and enhanced the credit as follows:
- 30% credit for qualifying residential solar installations placed in service from 2022 through the end of 2032
- 26% for systems placed in service in 2033
- 22% for systems placed in service in 2034
- No credit for residential systems placed in service after December 31, 2034
This schedule — 30% through 2032, then a two-step phase-down — is the law of the land as of the date of this article. The IRA overrode an earlier, pre-IRA schedule that would have reduced and then eliminated the credit sooner.
The credit is non-refundable, covers qualified system costs (panels, inverters, wiring, labor, battery storage of 3 kWh or more, and sales tax on eligible equipment), and requires that you own the system — leased systems pass the credit to the financing company, not the homeowner. Any unused credit can be carried forward to future tax years. For a full walkthrough of how the credit works and how to file Form 5695, see our guide to the federal solar tax credit.
What the House-Passed Reconciliation Bill Would Change
On May 22, 2025, the U.S. House of Representatives narrowly passed a reconciliation bill widely referred to as the “One Big Beautiful Bill.” Among its provisions, the bill would eliminate the Section 25D residential clean energy credit for systems placed in service after December 31, 2025.
Under the House bill:
- Residential solar installations completed by December 31, 2025 would still qualify for the 30% credit
- Residential solar installations completed on or after January 1, 2026 would receive no federal residential tax credit
- The bill does not phase the credit down — it cuts it off entirely for new residential installations
The Solar Energy Industries Association (SEIA) called the bill “unworkable” and expressed intent to work with the Senate on modifications.
What the bill does preserve: The commercial ITC (Section 48), which covers business, nonprofit, and certain third-party owned residential systems, is treated differently. The manufacturing tax credit (45X, which incentivizes domestic solar panel production) is reported to remain intact through 2029 in the House version. But the residential homeowner credit — Section 25D — would be gone.
Critical Caveat: The Bill Has Not Become Law
As of late May 2025, the reconciliation bill has passed the House and moved to the Senate. It has not been voted on by the Senate and has not been signed by the President. It is not law.
The Senate typically amends reconciliation bills significantly. Several Republican senators had previously written opposing “full-scale repeal” of IRA clean energy credits, suggesting the Senate version may differ from the House version. The outcome — whether the credit is eliminated, modified, or preserved — is genuinely unknown.
What this means for homeowners:
- Installations completed in 2025 are on solid legal ground under both current law and the House bill — the 30% credit is available either way.
- Installations expected to be completed in 2026 or later face real uncertainty. If the Senate passes the House version and it is signed, there is no residential credit. If the Senate modifies or rejects that provision, the IRA schedule may survive.
- No one can tell you right now what the law will be in 2026. Anyone claiming otherwise is speculating.
What “Placed in Service” Means — and Why It Matters for Timing
For tax credit purposes, a system must be placed in service in the tax year you claim the credit. “Placed in service” generally means the system has been installed, inspected by the local authority having jurisdiction (AHJ), and interconnected to the grid — or, for off-grid systems, otherwise operational. It is not the date you sign a contract, pay a deposit, or even the date the panels are physically mounted.
This is important right now because:
- A contract signed in October 2025 for an install that is not interconnected until February 2026 would be a 2026 placed-in-service date — not 2025.
- Installation timelines vary by contractor, utility, and AHJ. Interconnection queues can add weeks to months in busy markets.
- If the Senate passes the House bill’s Section 25D elimination, a February 2026 placed-in-service date would mean no residential credit under the new law.
If timing relative to the credit matters to your decision, the relevant date to track is when your utility will grant interconnection approval — not when installation begins.
What Still Qualifies Under Current Law (Before Any Senate Action)
Under the IRA as currently enacted, the following costs qualify for the 30% credit through 2032:
- Solar PV panels and modules
- Inverters (string, microinverter, and power optimizers)
- Balance-of-system hardware (racking, conduit, disconnect switches, monitoring equipment)
- Labor costs for on-site installation, wiring, and commissioning
- Permitting fees directly tied to the installation
- Sales tax on qualifying equipment
- Battery storage with a capacity of at least 3 kWh, including standalone batteries added to an existing system (this standalone eligibility was clarified by the IRA in 2023)
- Solar water heating systems certified by the Solar Rating Certification Corporation (SRCC), provided solar supplies at least half the energy used
What does not qualify: roof replacement costs unrelated to the structural requirements of the solar mount, extended warranty products, swimming pool or hot tub heating, and any equipment for a system you do not own.

A Note on Conflicting Information You May Have Seen
You may have encountered IRS documents that say the credit “is not available for any property placed in service after December 31, 2025.” This language has appeared in certain IRS instructions and creates understandable confusion alongside the IRA’s 2032 expiration date.
The most likely source of this conflict: the IRS Form 5695 instructions are updated periodically, and different versions reference different versions of the law. The pre-IRA expiration was December 31, 2023 (under the prior schedule); the IRA reset that to 2034. The “2025” reference may reflect an intermediate version of the law or a publication not yet updated to reflect the IRA amendment.
What this means practically: Do not rely on any single document, contractor claim, or news headline to determine your eligibility. The IRS’s current, live Residential Clean Energy Credit page is more authoritative than archived instruction PDFs. A tax professional can review the current statutory text of Section 25D for your specific situation.
How Leases and PPAs Are Affected
Homeowners who lease solar panels or sign a Power Purchase Agreement (PPA) do not own the system and cannot claim Section 25D for themselves. Under these arrangements, the system owner (the installer or a financial partner) claims the credit.
This dynamic is not changed by the House reconciliation bill’s residential credit elimination — if Section 25D is eliminated, the financier loses access to it for new residential systems too, which would affect the economics they can offer in lease and PPA contracts. The SEIA’s opposition to the bill cites this as a significant concern for third-party ownership business models.
The commercial ITC (Section 48) is a separate provision and has its own treatment in the reconciliation bill. If you are evaluating a lease or PPA, ask the installer specifically how any federal legislative changes are reflected in the proposed economics and whether the agreement provides any protection if the tax credit they’re counting on is reduced.
What Homeowners Should Do Right Now
Given the genuine uncertainty, here is a reasonable framework:
If you were planning a 2025 installation: The 30% credit is available under current law and would be preserved even under the House bill. If your timeline allows completing installation and interconnection before December 31, 2025, your credit eligibility is as solid as it can be under the current legislative environment. Get your quotes, confirm installer lead times, and ask explicitly when your utility can schedule interconnection — that is your binding constraint, not the panel delivery date.
If you were planning a 2026 or later installation: Be transparent with yourself that the credit may or may not be available. Run your economics both with and without the 30% credit. If the deal makes financial sense without the credit — because your electricity rate is high, your roof is well-suited, and the 25-year ownership math works — then the credit is a bonus rather than a requirement. If the deal only makes sense with the credit, wait for Senate clarity before signing.
For anyone considering a lease or PPA: The credit math for third-party-owned systems is more opaque and more exposed to changes in business model economics. Ask for written disclosure of how the quoted rate would change if the company’s tax credit assumptions change.
In all cases: Confirm current credit eligibility with a tax professional who can review the current statute — not just with an installer whose compensation depends on the sale.

Frequently Asked Questions
Is the 30% federal solar tax credit still available in 2025?
Yes, for systems placed in service (installed, inspected, and interconnected) in 2025. Both the current Inflation Reduction Act schedule and the House-passed reconciliation bill preserve the credit for 2025 installations.
Did the Big Beautiful Bill eliminate the solar tax credit?
The House passed a reconciliation bill in May 2025 that would eliminate the Section 25D residential solar credit for new installations after December 31, 2025. However, as of late May 2025, the bill had not passed the Senate and had not been signed into law. It is not currently effective.
What happens to the solar tax credit if I sign a contract in 2025 but my system isn’t installed until 2026?
The credit is determined by when the system is placed in service — typically when it is interconnected and operational — not when you sign a contract or make a deposit. A 2026 placed-in-service date would not qualify under the House bill if it becomes law. Confirm your installation and interconnection timeline with your installer and utility before relying on a 2025 credit.
Can I still get a solar tax credit on a leased system?
No. If you lease the panels, the system owner (not you) claims the credit. This is true under current law and would remain true if the House bill becomes law — the financier would simply lose access to the credit for new residential installations, affecting the rates they can offer.
Where should I check for the most current information on the residential solar tax credit?
The IRS’s official Residential Clean Energy Credit page at irs.gov is the primary authoritative source. For state-level incentives, the DSIRE database (dsireusa.org) is maintained by NC State University and updated regularly. A CPA or enrolled agent specializing in energy credits can advise on your specific situation.
Will the Senate preserve the residential solar tax credit?
No one can confirm this in advance. The Senate has not yet voted on the reconciliation bill, and Senate Republicans have expressed divergent views. The outcome is uncertain as of the publication date of this article.
