Key Takeaways
- Federal energy tax credits changed significantly in 2025 due to the One Big Beautiful Bill, with some incentives previously lasting through 2032 now expire at the end of 2025, while major EV credits expired for vehicles acquired after September 30, 2025.
- The Energy Efficient Home Improvement Credit (25C) offers up to $3,200 per year, combining $1,200 for general improvements and $2,000 for heat pumps and biomass systems, though most labor costs are excluded.
- The Residential Clean Energy Credit (25D) provides a 30% credit for solar, geothermal, storage, and other renewable systems, allows carryforward, and includes special rules for new construction completed and occupied by December 31, 2025.
- EV credits for new, used, and commercial clean vehicles (30D, 25E, 45W) all ended for vehicles acquired, not delivered, after September 30, 2025, and all remain nonrefundable with no carryforward allowed.
- The EV Charging Equipment Credit (30C) continues through June 30, 2026, offering up to $1,000 for qualifying home chargers and up to $100,000 per commercial charging port, with higher business rates requiring prevailing wage and apprenticeship compliance.
- Most energy credits are nonrefundable and documentation requirements are strict. The Residential Clean Energy Credit (25D) allows unused amounts to carry forward to future years, while the Energy Efficient Home Improvement Credit (25C) does not. Taxpayers can still amend prior returns within the IRS deadline to claim missed credits.
As homeowners and drivers look for ways to cut energy costs, save money on upgrades, and transition into cleaner technology, federal energy tax credits continue to play a major role. But in 2025, the rules look different from previous years. Due to the One Big Beautiful Bill, all major energy credits now expire by the end of 2025, much sooner than originally planned. The electric vehicle credits expired even earlier on September 30, 2025, while home energy credits remain available through December 31, 2025. Knowing which credits are still available, how they work, and when they expire is essential if you want to maximize your savings before major changes take place.
This guide walks through every major energy tax credit available in 2025, including home improvement incentives, solar and renewable energy credits, electric vehicle tax credits, and the greatly overlooked EV charging equipment credit. It also clarifies IRS rules around “acquiring” a vehicle before the deadline, explains which credits are refundable or carry forward, and highlights common misunderstandings that could cost you money.
Changes Under the One Big Beautiful Bill
Because Congress passed the One Big Beautiful Bill in July 2025, many energy tax credits will now end after December 31, 2025 — much sooner than originally planned. If you’re thinking about energy-efficient home upgrades or installing renewable energy systems, you’ll need to finish the work and claim the credit by the end of 2025. The new, faster deadline means timing is more important than ever.
Expiration Dates
| Code Section | Section Title | Termination Date |
| 25C | Energy efficient home improvement credit | Not available for improvements placed in service after December 31, 2025 |
| 25D | Residential Clean Energy Credit | No credit allowed for qualified expenditures made after December 31, 2025. |
| 25E | Previously-Owned Clean Vehicle Credit | Cannot be claimed for used clean vehicles acquired after September 30, 2025. |
| 30C | Alternative Fuel Refueling Property Credit | Ends for charging equipment installed after June 30, 2026. |
| 30D | New Clean Vehicle Credit | Not permitted for new EVs acquired after September 30, 2025. |

| 45W | Qualified Commercial Clean Vehicle Credit | Not allowed for commercial clean vehicles acquired after September 30, 2025. |
| 179D | Energy Efficient Commercial Buildings Deduction | Deduction unavailable for property whose construction begins after June 30, 2026. |
Energy Efficient Home Improvement Credit
Before diving into larger renewable energy systems, homeowners often start with efficiency upgrades like insulation, windows, doors, and energy-efficient HVAC systems. The Energy Efficient Home Improvement Credit makes many of these improvements more affordable, but it has strict rules, yearly caps, and very specific limitations on what counts toward labor. However, the One Big Beautiful Bill passed in July 2025 and shortened the credit’s availability to end on December 31, 2025. This means 2025 is your final opportunity to claim this credit, making strategic timing of improvements essential for maximizing tax savings.
What the Credit Covers
The Energy Efficient Home Improvement Credit allows you to claim 30% of the cost of qualified improvements. The IRS divides this credit into two separate buckets, and the distinction matters. The first bucket allows up to $1,200 per year for general improvements such as insulation, windows, doors, ventilation upgrades, certain energy-efficient HVAC components, and home energy audits. The second bucket provides up to $2,000 per year for heat pumps, heat pump water heaters, biomass stoves, and biomass boilers. Together, these two buckets allow a combined maximum of $3,200 per year, the absolute most a homeowner can receive under 25C in a single year.
Labor Eligibility and Limitations
Labor costs eligibility varies significantly by the type of improvement. The tax credit usually covers the cost of the actual equipment, but the IRS only lets you count labor costs in certain cases. You can include labor for heat pumps, heat pump water heaters, biomass stoves, biomass boilers, and some electrical panel upgrades (but only when the upgrade is needed for the qualifying equipment). These items fall under the $2,000 category, and both equipment and installation labor count toward that limit.
You cannot include labor for things like windows, doors, insulation, home energy audits, and most upgrades in the $1,200 category. For those, only the cost of the materials/equipment is eligible. The installation labor does not qualify and must be paid separately.
This matters for tax planning. It’s best to have labor separated out on your invoices. If labor for non-qualifying items gets mixed in, it can make the credit harder to calculate. The $1,200 annual limit mostly applies to equipment costs, while the $2,000 limit (heat pumps and biomass systems) includes both equipment and labor.
Refundability
The Energy Efficient Home Improvement Credit is nonrefundable and cannot be carried forward. Homeowners who cannot use the full credit in the year it is claimed will lose the unused portion. Because of this, some homeowners intentionally stagger energy improvements across multiple years to capture the maximum allowable credit annually.
Residential Clean Energy Credit (25D)
For homeowners looking to make larger renewable energy investments, the Residential Clean Energy Credit provides one of the most generous incentives available. Systems such as solar panels, solar water heaters, geothermal heat pumps, wind turbines, and battery storage can dramatically reduce long-term energy costs, and the tax credit significantly reduces the upfront expense.
What Qualifies
The 25D credit equals 30% of the total system cost, including equipment, labor, permitting, and installation. Unlike the home improvement credit, this credit has no annual or lifetime dollar limits. Eligible systems can be installed on a primary residence, secondary residence, or in some scenarios a mixed-use property where the taxpayer resides part of the year.
Construction / Original-Use Deadline
For construction or reconstruction projects, the expenditure is treated as made when the taxpayer’s original use of the constructed or reconstructed structure begins. That means for new-construction homes the structure must be completed and the taxpayer’s original use begun (i.e., occupied) by December 31, 2025 in order for the 25D credit to be claimed. If the taxpayer’s original use of the property begins after December 31, 2025, the credit is not available even if payments were made earlier.
Carryforward Rules
Contrary to some secondary sources, IRS Form 5695 and the current IRS instructions allow a Residential Clean Energy Credit (25D) amount that exceeds your tax liability in a given year to be carried forward to subsequent years. Form 5695 specifically includes lines for entering a credit carryforward and for calculating a credit carryforward to 2026.However, note that the One Big Beautiful Bill has set energy credits, including the Residential Clean Energy Credit, to expire after December 31, 2025. This means that new construction occupied after this date would not qualify for the credit under current law.
If you’re building a new home and planning to install qualifying renewable energy systems, timing is critical. Work with your builder to ensure the home is completed and you can take occupancy before the December 31, 2025 deadline. Making payments earlier does not qualify you for the credit if you don’t occupy the home by year-end.
Electric Vehicle Credits and Their September 30, 2025 Deadline
Electric vehicle credits have received significant attention in recent years, but the rules for 2025 are unusually time-sensitive. Three major EV credits expire for vehicles acquired after September 30, 2025:
- New Clean Vehicle Credit (30D)
- Used Clean Vehicle Credit (25E)
- Qualified Commercial Clean Vehicle Credit (45W)
The definition of “acquired” is especially important for taxpayers hoping to qualify before the deadline.
New Clean Vehicle Credit (30D)
The New Clean Vehicle Credit offers up to $7,500 for qualifying new EVs. To meet the requirements, the vehicle must fall under strict price caps, satisfy sourcing and assembly rules, and the taxpayer must fall within the income thresholds: $150,000 for single filers, $225,000 for heads of household, and $300,000 for joint filers. The credit remains nonrefundable and cannot be carried forward.
Used Clean Vehicle Credit (25E)
The Used Clean Vehicle Credit provides up to $4,000, or 30% of the sale price, whichever is less. The used EV credit has lower income limits: $75,000 for single filers; $112,500 for heads of household; and $150,000 for joint filers. These numbers are correct and remain unchanged. As with the new EV credit, this credit is nonrefundable and cannot be carried forward.
Commercial Clean Vehicle Credit (45W)
Commercial clean vehicles qualify for a separate credit under Section 45W, calculated using battery capacity or the price differential between the clean vehicle and its gas-powered equivalent. These credits also expire for vehicles acquired after September 30, 2025.
Clarifying “Acquired” vs. “Placed in Service”
Taxpayers should pay close attention to the IRS definition of “acquired.” A vehicle is considered acquired when a binding written contract is signed and payment is made on or before September 30, 2025. The vehicle does not need to be delivered or placed in service by that date. Taxpayers may take delivery afterward and still qualify. Delivery delays or manufacturer backlogs do not invalidate the credit as long as the binding contract requirement is met.
EV Charging Equipment Credit (30C)
Many taxpayers overlook the Alternative Fuel Refueling Property Credit, which remains available longer than the vehicle credits themselves. Unlike the vehicle credits and home energy credits, the EV Charging Equipment Credit (30C) was not shortened by the One Big Beautiful Bill and continues through its original expiration date of June 30, 2026. This makes it one of the few energy-related tax credits still available beyond 2025.
For Homeowners
Homeowners can claim 30% of qualifying hardware and installation costs, up to a $1,000 cap, for chargers installed in eligible low-income communities or non-urban census tracts. The 30C credit covers not only the charging port but also directly associated property such as pedestals, electrical panels, conduit, and wiring that is used exclusively to service the EV charger.
For Businesses
Businesses may receive up to 30% of the cost if they meet prevailing wage and apprenticeship requirements. If they do not meet these requirements, they only qualify for the 6% base rate. The cap is far higher than the residential credit, allowing up to $100,000 per charging port. This makes it one of the most valuable credits available to commercial entities upgrading parking lots, fleets, or charging infrastructure.
As with most energy credits, 30C is nonrefundable and cannot be carried forward.
How to Claim Energy Tax Credits
Homeowners and vehicle owners will typically use Form 5695 for residential energy credits and Form 8936 for EV credits. Documentation should include receipts, manufacturer certifications, installation invoices, and any required contract agreements for EV acquisition.
Who Cannot Claim These Credits
Renters generally cannot claim home-improvement credits unless they personally pay for and own the improvements. High-income taxpayers may be excluded from EV credits based on income limitations. Taxpayers with zero federal income tax liability cannot benefit from nonrefundable credits such as 25C, 30D, or 25E. Landlords are limited in claiming credits unless the property serves as their personal residence during part of the year.
Should You File an Amended Return?
If you made qualifying energy upgrades in a prior year and failed to claim the credit, you may still correct the oversight. Taxpayers generally have three years from the date the original return was filed, or two years after the tax was paid, whichever is later, to file an amended return. Amending a prior return can also restore carryforward amounts for the Residential Clean Energy Credit if they were missed or miscalculated.
With energy credits expiring December 31, 2025, taxpayers who make qualifying improvements in 2025 should be especially careful to claim all eligible credits on their original return. While you can amend within the IRS timeframe, the compressed deadline makes it more important than ever to get your 2025 return right the first time, as these credits won’t be available for future improvements.
Frequently Asked Questions
Why are energy tax credits ending in 2025?
The One Big Beautiful Bill (July 2025) shortened many Inflation Reduction Act energy credits. Credits that once ran through 2032 or 2034 now end on December 31, 2025 (and EV credits end September 30, 2025). This major policy shift cuts long-term support for renewable incentives and puts pressure on homeowners and buyers to act quickly.
Can I claim energy tax credits if I don’t itemize?
Yes. Most federal energy tax credits, including the Energy Efficient Home Improvement Credit (25C), the Residential Clean Energy Credit (25D), and EV credits (30D, 25E, 45W), are available whether or not you itemize deductions. These credits reduce your tax liability directly, so you can claim them even if you take the standard deduction.
Who qualifies for an electric vehicle tax credit?
Eligibility depends on the type of EV credit. New EV credits (30D) require meeting income limits, vehicle price caps, final assembly requirements, and battery sourcing rules; used EV credits (25E) have lower income limits and apply only to qualifying previously owned EVs purchased from a dealer. Commercial clean vehicle credits (45W) apply to businesses purchasing eligible electric or fuel-cell vehicles.
How exactly does a tax credit work?
A tax credit directly reduces the amount of tax you owe, dollar for dollar. Nonrefundable credits (like 25C, 25D, 30D, and 25E) can reduce your tax liability to zero but cannot generate a refund; some, like the 25D clean energy credit, allow unused amounts to carry forward to future years. This makes credits more valuable than deductions, which only reduce taxable income.
Can I claim energy improvements on my taxes?
Yes, if the improvements meet IRS requirements. Homeowners can claim qualified upgrades like heat pumps, insulation, windows, solar systems, or battery storage using credits such as 25C and 25D, while EV charging equipment and clean vehicles qualify under credits like 30C and 30D. Each credit has its own rules for equipment types, installation dates, income limits, and annual caps.
Tax Help for People Who Owe
Energy tax credits can significantly reduce the cost of home improvements, renewable energy systems, and electric vehicles, but the One Big Beautiful Bill has dramatically compressed the timeline. What were once credits scheduled to last through 2032 or 2034 now expire at the end of 2025, creating a narrow window for taxpayers to act. The rules vary widely, documentation requirements are strict, and the accelerated deadlines mean that procrastination could cost thousands in lost tax benefits.
By planning upgrades strategically and knowing the rules before these credits change or expire, taxpayers can maximize their energy savings and take full advantage of the incentives still available.
