Who it applies to
Taxpayers who made qualifying energy efficiency improvements to their main home in 2023.
What changed this year, and why
The Energy Efficient Home Improvement Credit allows taxpayers to claim a percentage of qualifying expenses paid in 2023 for energy efficiency improvements to their main home. For 2023, the annual credit limit is $1,200.
Common questions
- Are there limits for specific types of improvements?
- Yes. Within the overall annual limit, there are separate sub-limits for different types of expenses, including windows and skylights, exterior doors, and home energy audits. Heat pumps, heat pump water heaters, biomass stoves, and biomass boilers have their own separate annual limit.
- What property qualifies?
- The credit applies to improvements made to a main home in the United States that the taxpayer owned during the tax year.
The annual limit is a ceiling over smaller ceilings
The overall annual credit limit of $1,200 functions as a ceiling that contains smaller, category-specific sublimits. No single item of qualified energy property can generate more than $600 in credit, and all exterior windows and skylights together share a combined limit of $600. Each qualifying exterior door is capped at $250, with a total of $500 allowed for all exterior doors combined. Heat pumps, heat pump water heaters, biomass stoves, and biomass boilers have their own $2,000 combined limit. Home energy audits are limited to $150. These per-item ceilings mean that the $1,200 annual limit is a maximum that can only be reached if a taxpayer incurs qualifying costs across enough different categories. A homeowner who spends thousands on a single improvement will still find the credit for that item restricted by its own sublimit.
However, this credit is limited as follows. • A total combined credit limit of $1,200 for qualified energy property. • A credit limit of $600 for any qualified energy property item. • A combined credit limit of $600 for all exterior windows and skylights. • A credit limit of $250 for any qualifying exterior door and $500 total for all qualifying exterior doors. • A combined credit limit of $2,000 for heat pump and heat pump water heaters; biomass stoves and boilers. • A credit limit of $150 for home energy audits.

Heat pumps get their own bucket
Heat pumps and heat pump water heaters, along with biomass stoves and biomass boilers, operate under their own separate annual credit limit of $2,000, which is distinct from the general $1,200 annual limit that applies to other qualified energy efficiency improvements. This separate bucket means that a taxpayer can claim up to $2,000 for heat pump installations in addition to the $1,200 available for other improvements like insulation, windows, and doors. The $2,000 limit replaces what was previously a lifetime cap of $500 for these items, reflecting the expanded incentive structure under current law. There is no lifetime limitation on the $2,000 annual credit for heat pumps and biomass equipment, allowing homeowners to claim the full amount each year they make qualifying installations, subject to the $2,000 ceiling for these specific items.
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
For the 2023 tax year, the Manufacturer's Certification serves as the primary documentation requirement for claiming the credit on qualified energy property. The taxpayer may rely on the manufacturer's written certification that a product qualifies as eligible property for the credit. This certification must be kept for the taxpayer's records but does not need to be attached to the tax return. The written certification provides assurance that the equipment meets the efficiency standards and other technical requirements necessary to qualify. Homeowners should retain these manufacturer certifications along with receipts and other documentation, as they may be needed if the return is examined by the IRS. The manufacturer's certification requirement applies across all categories of residential energy property, including central air conditioners, water heaters, furnaces, boilers, and other qualified equipment.
Manufacturer’s certification. For purposes of taking the credit, you can rely on the manufacturer’s certification, in writing, that a product is qualifying property for the credit. Don't attach the certification to your return. Keep it for your records.

What makes an audit claimable
To claim the credit for a home energy audit, the audit must meet specific certification requirements. Beginning January 1, 2024, the audit must be performed by a Qualified Home Energy Auditor or under the direct supervision of one. The auditor must be certified by a Qualified Certification Program at the time the audit is conducted. This ensures the auditor has met professional standards for evaluating a home's energy use and identifying improvements. During the 2023 calendar year, the certification requirement did not apply, providing a transition period before the rule took effect. Taxpayers claiming the credit should keep records showing the auditor's qualifications and the certification program under which they are credentialed, as these records support the claim if the return is examined. The credit for home energy audits is subject to its own per-item sublimit within the overall annual ceiling, meaning the audit credit cannot exceed the dollar cap established for that specific category of expense.

Subsidised money does not count
Amounts provided through subsidized energy financing cannot be used to calculate the energy efficient home improvement credit. This restriction applies to financing received under federal, state, or local programs where the principal purpose is to provide subsidized financing for energy conservation or energy production projects. In practical terms, if a homeowner receives reduced-interest loans, grants, or other subsidized funding to pay for qualifying improvements, those subsidized amounts do not count toward the credit calculation. Only out-of-pocket expenses or financing obtained at market rates qualify for the credit. This rule prevents double benefits where taxpayers would receive both subsidized funding assistance and a tax credit for the same expenditure, ensuring the credit applies only to costs actually borne by the taxpayer without special program support.
Subsidized energy financing. Any amounts provided for by subsidized energy financing can't be used to figure the energy efficient home improvement credit. This is financing provided under a federal, state, or local program, the principal purpose of which is to provide subsidized financing for projects designed to conserve or produce energy.
