Last updated: May 23, 2026
You may have paid for insulation, a heat pump, new windows, or another energy upgrade and now need to know one thing: can it still lower your tax bill, or did the federal credit end before you could use it?
Current status in 2026
The Energy Efficient Home Improvement Credit is no longer an open credit for new 2026 home improvement work. The IRS says the credit may be claimed for qualifying improvements made through December 31, 2025, and that energy efficient home improvement credits cannot be claimed for property placed in service after December 31, 2025. Check the IRS credit page before filing, because tax rules can change.
This means your first question is not only “Did I buy the right product?” It is also “Was the item installed and ready to use in 2025?” A signed contract, a deposit, or a product ordered in 2025 may not be enough if the system was not placed in service by the deadline.
If you already filed your 2025 tax return and forgot the credit, do not panic. The IRS FAQ says a taxpayer may generally amend a previously filed return to claim the credit if the normal refund time limits are met. Start with the IRS amended return page or ask a qualified tax preparer.
Do not wait for a tax credit if your home is unsafe
A tax credit is not emergency repair help. If you smell gas, see sparking wires, have a smoking electrical panel, have no safe heat in freezing weather, have no cooling during dangerous heat, or think carbon monoxide may be present, leave the unsafe area and call 911, your utility emergency line, or a licensed emergency contractor. For utility shutoff or energy-bill crisis help, call 2-1-1 or use 211 utility help.
What this credit was, and what it was not
The Energy Efficient Home Improvement Credit was a federal income tax credit for certain energy-saving upgrades to an existing main home in the United States. It was not a grant, not a check from a contractor, and not a rebate paid at the cash register.
A tax credit can reduce the federal income tax you owe. This credit was nonrefundable. That means it could not give you more back than the federal tax you owed, and unused amounts could not be carried forward to a later year. This rule matters for low-income households, retirees with little taxable income, and families who already had enough credits to reduce their tax to zero.
The IRS says the credit generally applied to an existing main home, not a newly built home. A landlord or other owner who did not live in the home could not claim it. Some home business use can affect the credit, so ask a tax preparer if part of the home was used for business.
The 2025 federal filing season opened January 26, 2026, for tax year 2025 returns. The IRS listed April 15, 2026, as the regular deadline for calendar-year filers, with an extension to October 15 to file if properly requested. Use the IRS individual filing page for current filing steps and deadlines.
Quick answer by situation
| What happened | What to do now | Likely result |
|---|---|---|
| You installed a qualifying item in 2025 and have not filed your 2025 return. | Gather receipts, product proof, QMID or PIN if needed, and use Form 5695 page. | You may be able to claim the credit if all rules are met. |
| You installed a qualifying item in 2025 but already filed without it. | Ask about Form 1040-X and keep all proof. | You may be able to amend if refund time limits are met. |
| You bought or signed a contract in 2025, but the work was finished in 2026. | Ask a tax professional before claiming. | The credit is unlikely if the property was placed in service after December 31, 2025. |
| You are planning a new 2026 energy upgrade. | Look for state rebates, utility rebates, WAP, LIHEAP, or local help. | Do not assume the federal 25C credit applies to the new work. |
Upgrades that may qualify for 2025 work
For 2025 work, the credit was generally 30% of certain costs, but each category had caps. The maximum possible annual credit was $3,200: up to $1,200 for many building envelope and energy property items, plus up to $2,000 for certain heat pumps, heat pump water heaters, and biomass stoves or boilers. The IRS FAQ on credit amounts gives the detailed categories.
Do not use this table as proof by itself. The exact product must meet the rule for the year it was installed. For many items, you need the model number, manufacturer certification statement, and qualified manufacturer information.
| Upgrade type | Possible 2025 credit limit | Important notes |
|---|---|---|
| Exterior doors | 30% of cost, up to $250 per door and $500 total | Doors had to meet applicable ENERGY STAR requirements. Labor did not count. |
| Exterior windows and skylights | 30% of cost, up to $600 total | Windows and skylights had to meet ENERGY STAR Most Efficient rules. Labor did not count. |
| Insulation and air sealing | 30% of cost, within the $1,200 annual cap | Materials had to meet the required code standard. Labor did not count. |
| Home energy audit | 30% of cost, up to $150 | For 2024 and later audits, the auditor had to meet qualified certification rules and provide a written report. |
| Central air conditioner | Up to $600 per item | It had to meet the required efficiency tier. Certain labor could count. |
| Natural gas, propane, or oil water heater | Up to $600 per item | It had to meet required efficiency standards. Certain labor could count. |
| Natural gas, propane, or oil furnace or boiler | Up to $600 per item | It had to meet required efficiency standards. Certain labor could count. |
| Electrical panel, subpanel, branch circuit, or feeder | Up to $600 per item | It had to support another qualifying upgrade and meet electrical requirements. Certain labor could count. |
| Heat pump or heat pump water heater | Up to $2,000 total for this special group | It had to meet required efficiency standards. Certain labor could count. |
| Biomass stove or boiler | Up to $2,000 total for this special group | It had to meet the thermal efficiency rule. Certain labor could count. |
Labor costs can be confusing
The IRS says labor can count for some residential energy property, such as heat pumps, water heaters, central air conditioners, furnaces, boilers, biomass equipment, and certain electrical work. The IRS also says labor cannot be included for exterior doors, windows, skylights, insulation, or air sealing. Review the IRS labor cost rules if your invoice mixes materials and labor.
Who may have qualified
For this credit, the home generally had to be your main home in the United States. It had to be an existing home you improved or added onto, not a new home. You generally could not claim the credit for a home you owned but did not live in.
- You may be a good candidate to check the credit if the project was installed and ready to use in 2025.
- You may be a good candidate if you paid federal income tax for 2025 and the credit would reduce that tax.
- You may be a good candidate if your receipts clearly separate eligible materials, equipment, labor, and rebates.
- You are probably not helped by this credit for new work placed in service in 2026.
- You are probably not helped if you had no federal tax liability to reduce.
- You should not claim a landlord-only rental project as your own main-home credit.
How to check and claim a 2025 credit
Use a careful paper trail. A good claim starts before the return is prepared.
- Confirm the install date. Find the paid invoice, work completion form, permit closeout, inspection record, or contractor statement showing the item was installed and ready to use in 2025.
- Identify the product. Write down the brand, model number, serial number if available, and product type. Do not rely on a salesperson saying “it qualifies.”
- Check the standard. For windows, doors, and skylights, use ENERGY STAR credits and product labels. For HVAC and water heating equipment, a contractor may need to check the CEE tier or a manufacturer certification statement.
- Get the QMID or PIN. For 2025 specified property, taxpayers could use a qualified manufacturer code in place of a product PIN. Start with the IRS manufacturer list, then ask the contractor or manufacturer for the correct code for your item.
- Subtract rebates if required. The IRS says some rebates, subsidies, and incentives may reduce the cost used to calculate the credit. Save rebate approval letters and ask a tax preparer how to handle them.
- Use the right tax form. The credit is figured on IRS Form 5695, Residential Energy Credits. Read the current Form 5695 instructions for the tax year you are filing.
- Keep records. Do not mail all backup documents unless the IRS asks, but keep them with your tax records.
Call script: ask a contractor for credit proof
“I am checking whether my 2025 project qualifies for the Energy Efficient Home Improvement Credit. Can you send me the paid invoice, install completion date, model number, manufacturer certification statement, and the QMID or PIN if the product needs one? Please also show any rebates or discounts separately.”
Call script: ask a tax preparer
“I had an energy upgrade installed in 2025 and may have missed the Energy Efficient Home Improvement Credit. Can you review my invoice, product documents, QMID or PIN, and 2025 tax return? I also need to know if I have enough tax liability for the credit and whether I should amend.”
Home energy audits have special proof rules
A home energy audit could qualify for up to $150 for 2025, but the written report mattered. For audits in 2024 or later, the IRS required the inspection and report to meet added rules, including use of a qualified home energy auditor. DOE keeps an auditor list of recognized certification programs. A simple contractor estimate was not the same thing as a qualifying home energy audit.
Other help for 2026 energy upgrades
If your project will happen in 2026, look for help that still exists now. The best option depends on your state, utility, income, and the type of work.
Start with DOE’s home upgrades page to compare energy upgrades and incentive paths. Then check your state energy office through state energy offices, because state programs open, pause, change contractors, or run out of funds at different times.
| Type of help | How it works | Best for | Where to start |
|---|---|---|---|
| Tax credit | Reduces federal income tax after you file a return. | People with eligible 2025 work and federal tax liability. | IRS Form 5695 and tax help. |
| Rebate | May reduce price before or after purchase, depending on the program. | People planning upgrades now, especially if state or utility programs are open. | ENERGY STAR rebate finder. |
| Weatherization | Local provider audits the home and installs approved measures. | Low-income homeowners and renters who need energy-bill relief. | DOE WAP application page. |
| LIHEAP | Helps with heating, cooling, crisis bills, and sometimes energy-related repairs. | Households behind on utility bills or facing unsafe heating or cooling conditions. | ACF LIHEAP search tool. |
| HUD counseling | Housing counselors help review budget, mortgage stress, and homeownership options. | Homeowners choosing between repairs, loans, or catching up on bills. | CFPB counselor search. |
Low-income households may need a different path
If you live on Social Security, disability income, a small pension, seasonal wages, or very low income, a nonrefundable tax credit may not help much. It only reduces tax you owe. It does not pay a contractor upfront.
The Weatherization Assistance Program is often a better first call for low-income energy problems. DOE says WAP is administered at the state and local level, and local providers may place eligible households on waitlists. The program may inspect the home, review energy bills, test for air leaks, inspect energy equipment, and approve cost-effective work. Eligibility rules can include income at or below 200% of the poverty guidelines or state LIHEAP criteria, depending on the state.
LIHEAP can also help with heating and cooling bills and crisis situations. Eligibility varies by state, household size, income, and benefits received. USAGov explains that federal weatherization and energy assistance programs can help lower heating and cooling costs, and it also warns that ads promising “free money from the government” for repairs are often scams. Read the USAGov warning before sharing personal information with a grant website.
Call script: ask about WAP or LIHEAP
“I need help lowering my energy bills and making my home safer. Do you handle Weatherization Assistance or LIHEAP in my county? If not, who is the local intake agency? What documents do I need, and is there a waitlist?”
Call script: ask a utility
“I am planning an energy upgrade and need to know what rebates or bill-assistance programs are available for my address. Do you offer rebates for insulation, heat pumps, water heaters, audits, or panel work? Do I need pre-approval before signing a contract?”
State rebates and HEAR programs are not the same as the tax credit
The Home Electrification and Appliance Rebate program, often called HEAR, is focused on low- and moderate-income households. ENERGY STAR says HEAR households are generally below 150% of area median income, and it lists maximum rebate amounts such as up to $8,000 for a heat pump for space heating and cooling, up to $1,750 for a heat pump water heater, and up to $14,000 total. States may restrict who can use the program, what products qualify, and how rebates are delivered. Check the HEAR rebate page and your state energy office before buying equipment.
Rebates can also change the cost used for a tax credit. For a 2025 project, save every rebate notice and discount document. A rebate that looks like “free equipment” on an invoice may affect the credit calculation.
Common mistakes that cause trouble
- Claiming 2026 work. The 25C credit ended for property placed in service after December 31, 2025, unless Congress changes the law later.
- Counting labor for windows or insulation. Labor for building envelope items was not included for this credit.
- Forgetting the QMID or PIN. Many 2025 claims need manufacturer identification information.
- Assuming every ENERGY STAR product qualifies. Some categories require a higher standard than basic ENERGY STAR certification.
- Claiming more than your tax liability. The credit was nonrefundable and unused amounts could not be carried forward.
- Not subtracting rebates when required. Incentives may reduce the eligible cost.
- Using a landlord rental project. The credit generally required a main home you lived in.
- Losing records. Keep invoices, product labels, certification statements, audit reports, and payment proof.
Scam warnings
Be careful with door-to-door offers, “government grant” ads, and contractors who say the IRS will pay for the whole job. The FTC says home improvement scammers may promise work, take money, and leave homeowners worse off. Read the FTC scam guide before paying a large deposit.
Also be careful with tax preparers who promise a huge refund without reviewing your documents. The IRS says to choose a tax professional carefully and to avoid people who will not sign the return they prepare. Review the IRS preparer tips if you need paid help.
What to do if you are delayed, denied, or overwhelmed
- If you are waiting on documents: ask the contractor and manufacturer in writing for the model number, QMID or PIN, and certification statement.
- If a tax software program rejects the claim: read the error message and compare it with the Form 5695 instructions. Do not guess numbers to make the form pass.
- If you already filed: ask about an amended return. Keep a copy of the original return, corrected Form 5695, receipts, and explanation.
- If the IRS sends a notice: answer by the deadline on the letter. Send copies, not originals, unless the IRS specifically asks.
- If you cannot afford tax help: check IRS free tax help. VITA and TCE sites can help qualifying taxpayers, though not every site handles every credit issue.
- If the 2026 project is too expensive: pause before taking a high-interest loan. Check WAP, LIHEAP, utility rebates, state rebates, and HUD-approved housing counseling first.

FAQs
Can I use the Energy Efficient Home Improvement Credit for a 2026 project?
In general, no. Current IRS guidance says the credit cannot be claimed for energy efficient home improvement property placed in service after December 31, 2025. Check the IRS before filing in case the law changes.
Can I still claim the credit for work installed in 2025?
Possibly. If the work was qualifying, installed and ready to use in 2025, and you meet the tax rules, you may be able to claim it on a 2025 return. If you already filed, ask whether an amended return is possible.
Does the credit give me cash for repairs?
No. It was a nonrefundable federal tax credit. It could reduce tax you owed, but it was not an upfront grant and could not pay a contractor for you.
Do renters qualify?
This credit was mainly for a taxpayer’s main home. Some energy programs, such as WAP or HEAR rebates, may help renters if the program rules and landlord permission requirements are met. Check the local program before buying anything.
What if my contractor says everything qualifies?
Ask for proof. You need the product type, model number, certification statement, paid invoice, install date, and QMID or PIN if required. A sales statement is not enough by itself.
Where should a low-income homeowner start in 2026?
Start with WAP, LIHEAP, 2-1-1, your utility, and your state energy office. A tax credit may not help if you do not owe enough federal income tax.
