|---|---|---|---|

| Heat pump and biomass annual credit limit | $2,000 | $2,000 | +$0 (+0.0%) |
Who it applies to
The credit is for someone who paid for qualifying energy improvements to an existing home they lived in during 2025 in the United States, and for most of the categories that home has to be their main home. It does not reach the construction of a new home, which is what separates it from the residential clean energy credit on the same form. You must be the original user of a qualified energy efficiency improvement, and the component has to be reasonably expected to remain in use for at least five years. Amounts provided by subsidized energy financing cannot be used, and a utility subsidy that was not included in your income reduces your cost before you figure the credit. Members of a condominium management association and tenant-stockholders in a cooperative are treated as paying their proportionate share of the association's costs. The credit is limited by your tax through the worksheet for line 31 of Form 5695.
What changed this year, and why
The 2025 Instructions for Form 5695 carry two changes that matter more than the amount. The credit ends: you cannot claim the energy efficient home improvement credit for expenditures or property placed in service after December 31, 2025. And beginning January 1, 2025, if you claim the credit for specified property placed in service during the year, you must report the four-character alphanumeric qualified manufacturer identification number, the QMID, for each item. The structure of the credit is unchanged. The lifetime limitation of the older nonbusiness energy property credit has been replaced by an annual credit limit, and the combined annual limit for qualified energy property is $1,200, with a separate annual limit of its own for heat pumps, heat pump water heaters, biomass stoves, and biomass boilers. The instructions also add a line for enabling property and a checkbox for condominium and cooperative owners with a fractional share.
Common questions
- What is the energy efficient home improvement credit limit for 2025?
- The credit is a percentage of what you paid, subject to an annual combined credit limit of $1,200 for qualified energy property. That $1,200 covers insulation and air sealing, exterior doors, windows and skylights, central air conditioners, water heaters, furnaces and hot water boilers, panelboard work, and home energy audits, each of which also has its own smaller cap. Heat pumps, heat pump water heaters, biomass stoves and biomass boilers sit outside it under a separate annual limit.
- Is the energy efficient home improvement credit a lifetime limit or an annual one?
- Annual. The instructions state that for this credit the lifetime limitation has been replaced by an annual credit limit, so the $1,200 ceiling refills each tax year rather than being used up once. The separate limit for heat pumps and heat pump water heaters, biomass stoves and boilers is likewise annual, and it replaced a prior lifetime limitation. Since the credit ends after 2025, the annual reset no longer helps beyond that year.
- Which home improvements qualify for the credit?
- Two groups. Building envelope components installed on your main home: insulation or air sealing material and systems, exterior windows and skylights, and exterior doors. And residential energy property: certain heat pumps and heat pump water heaters, central air conditioners, natural gas, propane or oil water heaters, furnaces and hot water boilers, certain biomass stoves and boilers, and improvements or replacements of panelboards, subpanelboards, branch circuits, or feeders. Home energy audit costs also count.
- What is a QMID and do I need one?
- A QMID is the four-character alphanumeric unique qualified manufacturer identification number for an item of qualifying property. Beginning January 1, 2025, if you claim the energy efficient home improvement credit for specified property placed in service in 2025, you must include the QMID for each item on the applicable line of Form 5695. Without a valid QMID for specified property, the instructions say you cannot claim the credit for it.
- Do labor and installation costs count toward the credit?
- It depends on the category. For the building envelope components, exterior doors, windows and skylights, and insulation, you do not include amounts paid for onsite preparation, assembly, or original installation, so only the material counts. For residential energy property such as heat pumps, air conditioners, water heaters, furnaces and boilers, you do include labor costs properly allocable to onsite preparation, assembly, or original installation.
- Can I claim the credit on a rental property or a new build?
- No. The energy efficient home improvement credit is only available for existing homes, and you cannot claim it for expenses related to the construction of a new home. The qualified energy efficiency improvements must be on your main home in the United States, and you can only claim that part of the credit for one main home. Residential energy property must be installed on or in connection with a home you used during the year.
- What counts as a home energy audit for the credit?
- An inspection of your main home in the United States with a written report that identifies the most significant and cost-effective energy efficiency improvements, including an estimate of the energy and cost savings for each. It must be conducted and prepared by a Qualified Home Energy Auditor or under one's supervision, and the auditor must be certified by a Qualified Certification Program at the time of the audit. The report names the auditor, their identifying number, and the certification program.
- How does the credit work if I share the home with someone else?
- Each occupant of a jointly occupied home files their own Form 5695 and takes an allocated share: the credit limit for the property, multiplied by a fraction of what you paid over the total paid by all occupants, with a box checked and a statement attached. If you and a neighbor shared the cost of property benefiting each of your main homes, you each figure the credit on your own share and the limit applies to each of you separately.
Every amount on this page is a published figure rather than yours. The Energy efficient home improvement credit headroom takes the number you enter and works it out against them, showing which published figure it used.
The credit ends with 2025
The Energy Efficient Home Improvement Credit is not available indefinitely. According to the IRS instructions, taxpayers cannot claim this credit for any expenditures made after December 31, 2025, or for property placed in service after that date. This means the credit has a hard expiration point. If you are planning energy-efficient upgrades to your home and want to benefit from this credit, you must ensure that both the expenditure date and the date the property is placed in service fall on or before December 31, 2025. After that date, the credit ceases to exist unless Congress acts to extend it. This termination applies specifically to the energy efficient home improvement credit under Section 25C; other energy credits may have different expiration rules.
You can’t claim energy efficient home improvement credits for expenditures or property placed in service after December 31, 2025.

The annual limit is a ceiling over smaller ceilings
The $1,200 annual ceiling does not apply to each individual purchase. Within that overall limit, the IRS imposes smaller ceilings on specific categories. For example, qualifying exterior doors have a per-door limit and a total cap for all doors combined. Windows and skylights share their own combined limit. Home energy audits have a separate, smaller limit. Heat pumps, heat pump water heaters, biomass stoves, and biomass boilers have their own distinct limit that does not count against the regular per-item ceiling. These sub-limits prevent the total credit from exceeding the annual maximum while allowing taxpayers to claim multiple types of improvements in the same year.
A credit limit of $250 for any qualifying exterior door and $500 total for all qualifying exterior doors.

Heat pumps get their own bucket
Heat pumps and heat pump water heaters, along with biomass stoves and biomass boilers, do not share the per-item limit that applies to other qualified energy property. Instead, these items operate under their own distinct annual ceiling. This separate limit is not subject to any lifetime maximum; it resets each year. Under prior law, these items were subject to a lifetime cap, but the current structure replaces that old limitation with an annual one. This annual reset means taxpayers can claim the full amount each year they make qualifying purchases, without reducing future eligibility.
Heat pumps and heat pump water heaters, biomass stoves and biomass boilers have a separate annual credit limit of $2,000 with no lifetime limitation, which replaces the prior lifetime limitation of $500.

The manufacturer number you must have
Starting in 2025, a new documentation requirement applies. When claiming the credit for specified property placed in service during the year, the taxpayer must include a specific identifier for each item. This identifier is a four-character alphanumeric code assigned by the manufacturer. The code is unique to each item and is called the qualified manufacturer identification number, or QMID. Without this number, the credit cannot be claimed for that item. This requirement ensures that only qualifying products from certified manufacturers receive the credit.
Beginning January 1, 2025, if you are claiming the energy efficient home improvement credit for specified property placed into service in 2025, you must include the four-character alphanumeric unique qualified manufacturer identification number (QMID) for each item.

What makes an audit claimable
A home energy audit is only creditable if it meets specific professional standards. The audit must be performed by a Qualified Home Energy Auditor, or under the direct supervision of such an auditor. The auditor must hold current certification from a Qualified Certification Program at the time the audit is conducted. The written report delivered to the homeowner must include the auditor's name and taxpayer identification number, an attestation of this certification, and the name of the certification program. These requirements ensure that only audits conducted by properly trained and credentialed professionals qualify for the credit.
Home energy audits. Beginning January 1, 2024, home energy audits must be performed by a Qualified Home Energy Auditor or under the supervision of a Qualified Home Energy Auditor. The Qualified Home Energy Auditor must be certified by a Qualified Certification Program at the time of the home energy audit.

Subsidised money does not count
The credit is calculated on amounts the taxpayer actually pays or incurs. If any portion of the cost is covered by subsidized energy financing, that portion cannot be counted toward the credit. Subsidized energy financing refers to funding provided under a federal, state, or local program where a principal purpose is to provide financing for energy conservation or energy production projects. Because the taxpayer did not bear the full economic cost of the improvement, the credit is not available on that subsidized portion. Only the taxpayer's own out-of-pocket investment in qualifying property counts toward the credit calculation.
Any amounts provided for by subsidized energy financing can't be used to figure the energy efficient home improvement credit.

New construction does not qualify, unlike its sibling credit
For the 2025 Energy Efficient Home Improvement Credit in the United States, the credit applies only to improvements made to homes that already exist. The IRS instructions make clear that the residential clean energy credit covers both existing homes and homes under construction, but the energy efficient home improvement credit is restricted to existing homes only. This means if you build a new home from the ground up, the costs of energy-efficient upgrades incorporated during construction do not qualify for this particular credit. The rule targets the credit at retrofits of the existing housing stock rather than new construction, which is why the instructions draw the distinction explicitly. Taxpayers planning new builds should not expect to claim the $1,200 annual credit limit for the efficiency improvements included in the original construction of the home.
The energy efficient home improvement credit (Part II) is only available for existing homes.

Unused credit is not carried forward, unlike the residential clean energy credit
For the 2025 Energy Efficient Home Improvement Credit in the United States, any portion of the credit that cannot be used in the current tax year because it exceeds your tax liability is lost. The IRS instructions show that for the residential clean energy credit, if you cannot use all of the credit because of the tax liability limit, you can carry the unused portion of the credit to 2026. However, the energy efficient home improvement credit has no such carryforward provision. This means if your total credit for the year reaches the $1,200 annual credit limit but your tax liability is insufficient to use the full amount, the remaining credit simply expires at the end of the tax year. The credit is nonrefundable and must be used entirely within 2025, with no mechanism to preserve unused amounts for later years. Taxpayers should plan their energy-efficient improvements accordingly, since the credit cannot be rolled over to offset future tax obligations.
If you can't use all of the credit because of the tax liability limit (that is, line 14 is less than line 13), you can carry the unused portion of the credit to 2026.

Without a valid manufacturer number for an item, that item gets no credit
For the 2025 Energy Efficient Home Improvement Credit in the United States, taxpayers claiming the credit for specified property must include a valid four-character alphanumeric qualified manufacturer identification number for each item. If you do not provide a valid QMID for an item, that item does not qualify for the credit. The IRS requires this manufacturer identification to verify that the property meets the necessary efficiency standards and is eligible for the credit. Beginning January 1, 2025, this QMID requirement applies to specified property placed into service in 2025. Without the proper QMID documentation, you cannot claim the $1,200 annual credit limit for that specific item, even if it otherwise meets all energy efficiency requirements. Taxpayers should obtain the QMID from the manufacturer at the time of purchase and retain it for their records when filing their return.
you must provide a valid QMID for each item.
