30% Federal Solar Tax Credit Ended: Homeowners Lose, Leases Win
30% Federal Solar Tax Credit Ended: Homeowners Lose, Leases Win
No, homeowners can no longer claim the federal solar tax credit on systems they own and place in service after December 31, 2025. If you installed solar in 2025, you still qualify and claim it on Form 5695 with your return. Going forward, the main way to still capture federal value is through a lease or power purchase agreement, where the system owner claims a separate commercial credit.
TL;DR:
- The federal solar tax credit ends for systems placed in service after December 31, 2025, and eligibility now depends strictly on the permission to operate date, not contract or payment dates.
- Only new equipment with at least 3 kWh capacity, installed at eligible residences before the deadline, qualifies for the 30% credit, excluding used, reinstalled, or non-certified products.
- Homeowners who installed systems in 2025 should file Form 5695 by April 15, 2026, with proof of permission to operate, while mid-contract or future buyers need to evaluate lease versus purchase options carefully.
- The loss of the homeowner credit shifts the financial advantage toward state and utility incentives, which vary widely and often depend on whether rebates reduce the cost basis for tax purposes.
- After 2025, system ownership structure determines who can claim federal credits, making leasing or PPA agreements more attractive for those who do not own their systems outright.

What is the federal solar tax credit and when did it end?
The federal solar tax credit, officially the Residential Clean Energy Credit under Section 25D of the tax code, paid homeowners 30% of the cost of a qualifying solar or battery system. It applied to systems placed in service between 2022 and the end of 2025, and then it stopped. The IRS is explicit about this: the credit is not available for property placed in service after December 31, 2025.
That phrase, “placed in service,” is where a lot of homeowners get tripped up. It doesn’t mean the date you signed a contract, and it doesn’t mean the date you paid a deposit or even the date the panels went on your roof. It means the date your system is fully installed, inspected, and granted Permission to Operate (PTO) by your utility, in San Diego’s case, SDG&E. A system that had panels mounted in November 2025, but didn’t get PTO until January 2026 missed the deadline. That is a brutal distinction for anyone who assumed a signed contract locked in their eligibility.
There was no gradual step-down here, and that’s worth sitting with for a second. This time, Congress didn’t build in a soft landing for homeowner-owned systems. One day the credit was worth 30% of your system cost. The next, for anyone who didn’t get PTO in time, it was worth zero.
By the numbers: key dates every homeowner should track
- December 31, 2025 — Last day a homeowner-owned solar or battery system could be placed in service and still qualify for the 30% Section 25D credit.
- April 15, 2026 — Standard filing deadline to claim the credit on your 2025 tax return (extensions push this to October 15, 2026).
- The begin-construction safe-harbor deadline for Section 48E, the commercial credit pathway that now covers third-party-owned systems like leases and PPAs, is in mid-2026.
If you’re not sure which side of that December 31 line your project fell on, your installer’s paperwork will tell you. Look for the PTO letter from your utility. That document, not your contract date, is the one the IRS cares about.
Here’s the part that catches people off guard: this wasn’t a slow phase-out debated for years. It came through the One Big Beautiful Bill Act (OBBBA). It moved fast enough that plenty of homeowners who started the solar process in mid-2025 assumed they had more runway than they actually did. Some installers had to scramble to get customers through permitting, inspection, and interconnection before the calendar ran out. If your installation stalled anywhere in that pipeline, that stall may have cost you thousands of dollars in credit value.
Who qualifies and what equipment counts?
Qualifying for the credit (for 2025 installs still inside the window) always came down to two questions: is your equipment eligible, and is it installed at an eligible residence? Both mattered as much as the placed-in-service date.
On the equipment side, the IRS and ENERGY STAR recognize several categories of qualified clean energy property:
- Solar electric panels (photovoltaic systems)
- Solar water heaters certified by the Solar Rating Certification Corporation or a comparable state entity
- Small wind turbines
- Geothermal heat pumps
- Fuel cell property
- Battery storage technology with a capacity of at least 3 kilowatt-hours
That battery threshold matters more than most people realize. A battery pulling less than 3 kWh of usable capacity doesn’t meet the bar, full stop. Most residential systems clear this easily. A single Tesla Powerwall runs about 13.5 kWh, and Enphase IQ and Franklin WH batteries are typically sized well above the 3 kWh floor too. But if you were shopping smaller backup units for a specific circuit, like a refrigerator or a sump pump, it was worth checking the spec sheet before assuming the credit applied.
What doesn’t count is just as important. Used or previously installed equipment never qualified, only new property does. Purely structural roofing work, the plywood decking, the trusses, general re-roofing unrelated to supporting the solar array, generally falls outside the credit basis. Where things get nuanced is with roofing components that also function as part of the solar system, like certain solar shingles or mounting-integrated products; those can sometimes count. Labor and installation costs, on the other hand, are includable. Wiring, mounting hardware, inverters, and the electrician’s or installer’s labor to put it all together count toward your 30% basis, not just the panels themselves.
Residence rules are more flexible than people expect. The credit applied to your main home and could also apply to a second home you use yourself, as long as you didn’t rent it out. A property you own purely as a rental, with no personal use, generally didn’t qualify, because the credit is designed for homeowners’ own residences, not investment property.
Pro Tip: Keep every piece of paperwork tied to your install, even after you file. That includes the signed contract, itemized invoice, equipment spec sheets showing battery capacity, and, most critically, your utility’s Permission to Operate letter. If the IRS ever asks questions, the PTO date is your proof of when the system was legally placed in service.
How do you actually claim the credit on your taxes?
If your system was placed in service by December 31, 2025, claiming the credit is a straightforward, if slightly technical, paperwork process.
- Fill out Form 5695, Residential Energy Credits, for the tax year your system was placed in service. This is the form where you calculate 30% of your qualified costs, battery, panels, inverter, labor, and everything else that counts toward the basis.
- Carry the result to Schedule 3 of your Form 1040, then onto your main return, where it reduces your tax liability dollar for dollar.
- File by April 15, 2026 for a 2025 installation, or request an extension to October 15, 2026, if you need more time to gather documentation.
- If you missed claiming it, you generally have up to three years to file an amended return using Form 1040-X, so a 2025 install isn’t lost even if you already filed without it.
One detail trips up a lot of first-time filers: this credit is nonrefundable. That means it can reduce your tax bill to zero, but the IRS won’t cut you a check for the difference if the credit is bigger than what you owe. Say your system earned you a $9,000 credit but you only owed $6,000 in federal tax that year. You’d zero out your liability and carry the remaining $3,000 forward to next year’s return, where it can offset future tax owed. This carryforward provision is genuinely useful, especially for retirees or anyone with lower taxable income who might not owe enough in a single year to use the full credit at once.
A couple of common mistakes worth flagging. First, rebates: if a utility or state program gave you an upfront rebate that functions as a purchase-price adjustment, it typically reduces your qualified cost basis before you calculate the 30%. Not every rebate works this way, so check the specific program’s structure rather than assuming. Second, don’t confuse the sales price with your actual out-of-pocket cost; if you financed the system with a loan, your qualified basis is still the full cost of the equipment and installation, not your monthly payment.
Why Section 25D ended and why ownership now decides everything
The mechanism behind this change is worth understanding, because it explains why your ownership structure now matters more than almost anything else in the solar-buying decision. Under OBBBA, Congress terminated Section 25D for any homeowner-owned residential system placed in service after December 31, 2025. That section, which had existed in some form since 2005, is simply gone for direct purchases now.
What remains is Section 48E, a commercial investment tax credit that was never designed with individual homeowners filing Form 5695 in mind. Section 48E is claimed by whoever owns the system as a business asset, typically a solar leasing company, a PPA provider, or a commercial developer.
- Domestic content bonus for systems using a qualifying percentage of American-manufactured components
- Energy community bonus for projects sited in areas tied to historic fossil fuel employment or closed coal facilities
- Low-income bonus for projects serving qualifying low-income housing or communities
Section 48E projects also face a begin-construction safe-harbor deadline of July 4, 2026, meaning the project must formally start construction by that date to lock in eligibility under current rules, separate from the placed-in-service test that governed the old homeowner credit.
Here’s where ownership structure changes everything for the two homeowners sitting on the same street. Homeowner A buys a system outright in March 2026. She owns the panels, she owns the battery, and she gets zero federal tax credit, because Section 25D no longer exists for her situation. Homeowner B, next door, signs a lease or PPA in March 2026. He doesn’t own the equipment, the financing company does, which means the financing company, not Homeowner B, can claim the Section 48E commercial credit. Some portion of that value may show up as lower monthly lease payments, but Homeowner B never sees a tax credit on his own return, because he isn’t the legal owner of the system.
This is the single biggest strategic decision facing anyone shopping for solar in 2026: the narrowing of federal incentives to ownership structure rather than a universal homeowner benefit makes the purchase-versus-lease question far more consequential than it used to be. It’s not just a financing preference anymore. It’s the difference between capturing federal value in some form and capturing none at all.
Battery storage and other technologies: what qualifies now?
Battery storage rules follow the same split as solar panels, because they lived under the same Section 25D umbrella. A homeowner-owned battery, whether it’s a Tesla Powerwall, an Enphase IQ Battery, or a Franklin WH unit, needed to clear the 3 kWh capacity threshold and be placed in service by December 31, 2025, to qualify for the residential credit. A homeowner-owned battery installed after that date gets no federal tax credit under Section 25D, regardless of how large or sophisticated it is.
This stings for anyone who was planning to pair a new solar system with battery backup for grid outages or to maximize self-consumption under NEM 3.0’s time-of-use rate structure.
The same third-party ownership pathway that applies to panels applies to batteries. If a leasing or PPA company owns the battery as part of a bundled system, that company can potentially access Section 48E and its adders, and depending on how the contract is structured, some of that value may be reflected in your monthly cost. It’s not automatic, and it varies by provider and contract terms, so ask directly.
If you’re weighing battery storage in 2026, a few concrete steps make sense before you sign anything:
- Check whether your state or utility offers a standalone battery rebate. California’s Self-Generation Incentive Program, for instance, has historically offered meaningful rebates for qualifying storage independent of the federal credit picture.
- Ask any installer or financing company directly whether they operate on an owner-of-system model and how, specifically, federal credit value gets reflected in your pricing.
- Compare the total cost of ownership on a lease versus a cash purchase now that the purchase side no longer carries a federal credit; the math has shifted meaningfully from where it stood in 2024.
- Get a written quote showing exactly what portion of your battery cost is offset by any incentive, state, utility, or otherwise, before you commit.
Where to look for state and utility incentives that fill the gap
With the federal homeowner credit gone, state and utility programs carry more weight in the overall value stack than they used to. That shift is real, and in states with high electricity rates and strong net metering policies, solar can still make financial sense even without a federal credit cushion.
A few things to understand before you assume a rebate will offset your costs. Some rebates function as purchase-price adjustments, meaning they reduce the cost basis you’d use for any remaining federal calculation, while others are structured as tax-free grants that don’t touch your basis at all. The distinction matters for tax reporting, and it’s not always obvious from a rebate program’s marketing materials.
California homeowners specifically should look at the Self-Generation Incentive Program, which has provided rebates for qualifying battery storage projects independent of federal credit changes. Beyond SGIP, the Database of State Incentives for Renewables and Efficiency, known as DSIRE, is the most reliable place to search state by state for current programs, since state legislatures and utilities update these offerings more frequently than most homeowners can track on their own.
Pro Tip: Before signing a contract, call your utility directly and ask two specific questions: is there an active rebate program for solar or battery storage right now, and does that rebate count as a purchase-price adjustment for tax purposes? Get the answer in writing if you can, and keep it with your other installation documents.
A short set of actions covers most of what you need here:
- Search DSIRE for your specific state and utility service territory.
- Call SDG&E or your local utility directly rather than relying solely on installer marketing claims about rebate eligibility.
- Ask explicitly whether any rebate offered reduces your qualified cost basis.
- Document every rebate approval, application, and disbursement alongside your other solar paperwork.
Your action checklist: installed, under contract, or still deciding
Where you land in the solar timeline determines exactly what you need to do next, and the right move looks different depending on your situation.
- If you completed installation in 2025: File Form 5695 with your 2025 return by April 15, 2026, or by October 15, 2026 with an extension. Pull your PTO letter from SDG&E or your utility to confirm the exact placed-in-service date, and keep it filed alongside your itemized invoice and equipment specs.
- If you’re under contract or mid-installation: Confirm with your installer, in writing, whether PTO was actually granted before December 31, 2025. A signed contract or even a completed physical installation doesn’t guarantee eligibility if utility interconnection and inspection dragged past that date.
- If you’re planning a new installation in 2026: Evaluate lease and PPA options against a cash purchase with real numbers, not assumptions. Ask any prospective installer how they structure ownership and whether federal commercial credits under Section 48E factor into your pricing. Layer in state and utility rebates as part of the comparison, since those now carry more of the financial weight than before.
- In every case: Keep a dedicated folder, physical or digital, for every contract, invoice, spec sheet, and utility document tied to your system. This documentation also matters for homeowners insurance purposes, not just taxes.
Pro Tip: Don’t rely on memory or a single email thread for your placed-in-service date. Request a dated copy of your Permission to Operate letter directly from your utility and store it somewhere you’ll actually find it again come tax season.
What San Diego homeowners should expect from a local installer in 2026
The rules changed. What a good installer does for you didn’t. A trusted local installer has operated in San Diego County for decades and pulled one of the first commercial solar permits issued in the City of San Diego. Thirty years, thousands of installations, and a policy will always outlast this particular tax provision.
What matters practically for homeowners navigating 2026 is having a partner who handles the parts of this process that determine whether you even qualify for anything. Getting Permission to Operate before a hard deadline isn’t a formality, it’s the entire ballgame for eligibility, and that comes down to how efficiently permitting, SDG&E interconnection, and inspection get coordinated.
For homeowners weighing a lease or PPA now that the direct-purchase credit is gone, the questions worth asking are specific: how is ownership structured, what happens to any Section 48E value, and how is that reflected, if at all, in your monthly cost. A local installer who has issued permits and coordinated utility interconnection for three decades has seen enough contract structures to walk you through the tradeoffs honestly, rather than pointing you toward whichever financing product pays the best commission.
None of this makes the lost federal credit for direct purchases sting less. It does mean the practical work, documentation, permitting speed, and clear financing comparisons, still determines whether your 2026 solar decision pays off.
