In May 2025, the U.S. House of Representatives passed the “One Big, Beautiful Bill,” which proposes significant changes to clean energy tax incentives:
- Early Termination: The 30% Residential Clean Energy Credit would end on December 31, 2025, instead of 2032 as previously planned. This would require systems to be installed and placed in service to qualify.
- Leased Systems: Tax credits for leased residential solar installations would be eliminated for any taxable year beginning after the bill’s enactment.
- Commercial Projects: Accelerated phase-out of commercial solar tax credits, with reductions starting in 2029 and complete elimination by 2031.
- Transferability: Elimination of the ability to transfer solar tax credits for projects starting after July 2027.
The solar industry stands at a critical juncture. On May 22, 2025, the U.S. House of Representatives passed the “One, Big, Beautiful Bill,” a legislative package that, if enacted, could significantly alter the landscape of solar tax incentives. This bill proposes substantial changes to the federal solar tax credits established under the Inflation Reduction Act (IRA), with far-reaching implications for both residential and commercial solar stakeholders.
Background on Solar Tax Credits
The Investment Tax Credit (ITC) has been a cornerstone of the U.S. solar industry’s growth, offering a 30% tax credit for residential and commercial solar installations. The IRA of 2022 extended this credit through 2032, aiming to promote clean energy adoption and reduce carbon emissions.
Proposed Changes in the Bill
1. Early Expiration of the 30% Residential Solar Tax Credit
- Current Status: Set to run through 2032 under the IRA.
- Proposed Change: Ends abruptly on December 31, 2025, with no phase-down period.
- Implication: A $30,000 system that qualifies for a $9,000 federal tax credit today will no longer be eligible after this deadline. Systems must be installed and inspected prior to the deadline to qualify.

2. Accelerated Phase-Out of Commercial Solar Tax Credits (45Y/48E)
- New Timeline:
-
- 80% credit in 2029
-
- 60% in 2030
-
- 40% in 2031
-
- 0% after 2031
- Urgency: Projects must begin within 60 days of the bill’s enactment to qualify.
- Impact: Developers must act quickly to secure incentives for commercial and utility-scale solar projects.
3. Elimination of Solar Tax Credit Transferability (Section 6418)
- Current Benefit: Transferable tax credits allow for greater financing flexibility.
- Proposed Change: Eliminated for projects starting after July 2027.
- Implication: This will limit financing options and could stall smaller solar projects.
4. Impact on U.S. Solar Manufacturing (Section 45X)
- Current Support: Incentives to build a domestic solar supply chain.
- Proposed Change: Slated to end by 2031.
- Result: Could lead to increased reliance on foreign solar panel imports, particularly from China, and impact clean energy job growth.

Frequently Asked Questions
No – at least not yet. The House of Representatives did pass a bill that would end the residential solar tax credit after 2025, but this is not final. The bill must also pass in the Senate and then be signed by the President to become law. There is strong opposition from solar advocates and many lawmakers (including some in the Senate) who support clean energy incentives. It’s possible the provision could be blocked or modified. However, given that the House has taken this position and the political landscape has shifted in 2025, we have to treat the threat as real. In other words, there’s a significant risk the credit could be reduced or eliminated early, so it’s best to plan as if 2025 may indeed be the last year for the full 30% credit for homeowners. If the Senate alters the bill or if a compromise extends the credit, that would be welcome news – but there’s no guarantee. We will update this guidance if the situation changes.
You are correct that the current law, established by the Inflation Reduction Act in 2022, set the Residential Clean Energy Credit at 30% for installations from 2022 through 2032, with a step-down to 26% in 2033 and 22% in 2034. Nothing has changed about that law yet. However, what’s happening now is that a new bill has been proposed (and passed by the House) to amend that law and cut the timeline short.
Until and unless that new bill is enacted, the original schedule remains in force – meaning the credit is still 30% today and will be 30% next year if no new law intervenes. The House’s action is an attempt to change the policy. Think of it this way: as of now, the solar tax credit is still “scheduled” to run at 30% for several more years, but there’s a strong push in Congress to reschedule its expiration to 2025.
That push has momentum, so one should not assume Congress won’t succeed. But technically, nothing has changed yet, which is why 2025 is so critical. It could be the final year of 30%, depending on what Congress does in the coming months.
No, unfortunately not – at least not the way the House bill is written. Tax credits for solar (under both current law and the proposed change) are claimed in the tax year that the system is “placed in service.”
This generally means fully installed and utility-approved for operation. It’s not based on when you sign a contract or purchase equipment. So if the law changes to cut off the credit after 2025, any system completed in 2026 or later would not be eligible congress.gov.
For example, say you sign a contract in fall 2025, but due to interconnection delays, your system isn’t turned on until January 2026 – in that case, as the proposal stands, you would miss out on the credit (since placed-in-service occurred in 2026). That’s why we strongly recommend aiming to finish projects by mid-to-late 2025 at the latest. If it appears your installation might slip, talk to your installer about expediting or see if partial completion by year-end is possible (though partial doesn’t count for the credit; it needs to be fully operational). Important: If, hypothetically, Congress only passes a repeal in early 2026, there’s a slim chance they’d allow a grace period or grandfathering for projects in progress – but you cannot bank on that. The House bill explicitly set the cutoff at the end of ’25 with no extensions congress.gov. So, proceed with the assumption that completion by 2025 is the rule.
Yes, it does, though not as abruptly as the residential credit. The House bill proposes that the Commercial Solar ITC (Investment Tax Credit) remain at 30% through 2028, then phase down starting in 2029, reaching 0% by 2032.
Under current law, commercial projects also get 30% for the foreseeable future (with a potential phase-out later in the 2030s depending on carbon reduction progress). So the bill accelerates the timeline for businesses too, just with a few more years of runway.
Businesses would see 24% in 2029, 18% in 2030, 12% in 2031, and no credit for projects after that.
It’s also worth noting the bill’s provision to exclude third-party owned residential systems from claiming the commercial ITC under Section 48. That means solar companies can’t switch tactics and use the commercial credit for leased residential systems if the homeowner credit is gone – both paths would be blocked for new installs post-2025.
So, commercial and utility-scale solar interests are affected, though arguably the biggest immediate impact is on the residential side which gets the guillotine rather than a taper. If you’re a business or non-profit (using a taxable partner via tax equity), you should still act before 2029 to secure the full 30%, and consider that large projects often take multiple years to develop – hence, decisions in the next year or two are important. Leasing a solar energy system for your home will save you money on your monthly utility costs as well. While the savings are usually a little less attractive than owning solar panels, you’ll still save significantly over the traditional costs of electricity from the utility.
Leasing carries several other advantages, including worry-free system performance for the length of the contract. That means any equipment maintenance or replacement, even after the product warranty expires, is the responsibility of the leasing companies. Lease terms tend to be 20-25 years and often come with a production guarantee. For homeowners who cannot absorb the Federal Tax Credit, leases are an attractive option. A solar lease allows the third-party owner (TPO) to absorb the solar tax credit, then pass some of the savings on to the homeowner.
If the federal credit ends, solar in states without their own tax credit will lose a major portion of its financial incentive. You would be relying on the long-term utility bill savings, any net metering credits, and perhaps smaller incentives like rebates or property tax exemptions to make the economics work.
In California, for example, the federal 30% ITC has been a key part of solar payback calculations, especially now that Net Metering 3.0 has reduced the value of exporting solar energy to the grid. Without the ITC, a typical California homeowner might see payback times lengthen significantly (potentially several years longer). That said, California still has some of the highest electricity rates in the nation, so solar will continue to provide substantial savings on bills – it just will cost more upfront.
California also offers the Self-Generation Incentive Program (SGIP) for batteries and has a property tax exclusion for solar (meaning your property taxes won’t increase due to adding solar).
Those help a bit. In states like Nevada (no state income tax, thus no state credit) or Texas (no state credit), the scenario is similar: solar remains a good long-term investment to hedge against utility costs, but the loss of the 30% credit would make the initial investment higher. We encourage homeowners in these states to take advantage of the credit while it’s available.
We can also explore alternative financing and promotions (for instance, some installers may offer discounts or cashback deals, and there are often referral bonuses) to defray costs.
In short, the economics in no-credit states will still favor solar in many cases (due to high sun exposure or electricity prices), but the proposition is strongest with the credit – so its potential removal is definitely felt.
It’s always possible – the solar ITC has been extended multiple times in the past (2008, 2015, 2020, 2022). If, for example, political leadership changes in the future or if there’s a strong economic push for clean energy, Congress could vote to reinstate or even increase incentives.
However, betting on future policy is risky. The current effort is to eliminate it early, which is the opposite of an extension. If that succeeds, a revival would require passing a new law, presumably under an administration that prioritizes clean energy.
The soonest scenario for that might be after the next elections, etc., and there’s no guarantee. Also, once an industry incentive expires, it’s historically been harder to bring it back (extensions typically happen before expiration). The best strategy if you want the benefit is to use what’s on the books now. Think of the credit as a use-it-or-lose-it opportunity at the moment. If circumstances change and the credit is still around or comes back in some form, then great – but you wouldn’t have lost anything by going solar sooner.
In fact, you’d be benefiting from lower energy bills in the meantime. So our advice is to plan under the assumption the 30% credit won’t be around after 2025 (for residential) – and if it does survive or get re-extended, that’s a bonus (perhaps you could then claim it again on a battery upgrade or a second property, etc.). We’ll keep you updated on any political shifts that suggest a turnaround.
As of now, claiming the credit involves filing IRS Form 5695 (Residential Energy Credits) with your federal tax return for the year in which your solar was placed in service.
You calculate 30% of your qualified costs and that amount reduces your tax liability dollar-for-dollar. If the credit is larger than what you owe in taxes for that year, you can roll over the remainder to future years. None of that basic mechanism changes with the proposed legislation – the only change is whether the credit is available at all for a given year (and at what percentage). So if the bill passes, the IRS form would simply not have a residential solar credit line after 2025 (and eventually the form would be retired once all such credits are phased out). But for installations in 2023-2025, you would still use the form normally under existing rules.
A couple of reminders: you need to have a tax liability to use the credit (it’s nonrefundable – it won’t give you a negative refund beyond your tax due). Most working homeowners do have enough tax liability over a multi-year period to utilize it. Also, keep records of your expenditures (inverter, panels, mounting, electrical upgrades related to solar, permitting fees – all these count as eligible costs).
SolarTech provides our customers with a comprehensive packet and guidance for claiming the credit, and we stay updated on IRS rules.
If the bill passes, the IRS would issue updated guidance, but typically, any installations while the credit was law remain valid to claim. Always consult a tax professional if unsure. And note: the proposed bill does not claw back credits from people who already claimed them in past years – it only affects availability going forward.
Yes. State, local, and utility incentives are independent of the federal tax credit.
They each have their own funding sources and rules. For instance, if your state offers a rebate for solar, you will still get that rebate whether or not there’s a federal credit.
One thing to consider, however, is that some state incentives are calculated after the federal credit, or vice versa. For example, a state might allow you to claim their credit only on the portion after federal credit – those details vary.
Arizona’s $1,000 credit is a flat amount, so it’s unaffected by the presence of the federal credit (you’d just be more thankful for that $1k if the 30% is gone). Another consideration: if the federal credit disappears, state legislatures might introduce or expand state incentives to fill the gap – but again, that’s speculative and may take time. The reliable approach is to utilize whatever is currently on the table.
Many utilities have net metering caps or are reducing solar buyback rates, so that’s another reason to act sooner – you lock in any favorable terms before they potentially worsen.
On the flip side, if federal support is withdrawn, some states might strengthen net metering or mandates as a response to ensure solar adoption continues (we’ve seen states step up when federal policy lags, and vice versa). In summary, you will still benefit from other incentives like local rebates, state tax credits, solar renewable energy certificates (SRECs), etc., if available in your area. Our team can provide a full incentives overview for your location – check out our Solar Incentives by State resources or give us a call.
Even without the federal credit, going solar often makes financial sense, especially as utility rates rise. But with the credit, the case is outstanding, so you can imagine why we’re keen on helping folks capture it.
