IRS Publication 5797 – Are you searching for IRS Publication 5797 to understand home energy tax credits? This official IRS guide explains the Energy Efficient Home Improvement Credit and Residential Clean Energy Credit—two powerful incentives expanded by the Inflation Reduction Act of 2022.
Important 2026 update: These credits expired for installations after December 31, 2025. You can still claim them on your 2025 tax return (filed in 2026) if the improvements were placed in service by the end of 2025. Publication 5797 (revised June 2023) remains the quick-reference overview, but current IRS rules reflect the shortened timeline.

This comprehensive article pulls directly from IRS.gov (including Publications 5797, 5967, 5968, and detailed credit pages updated in 2026) to help you determine eligibility, calculate potential savings, and file correctly.
What Is IRS Publication 5797?
IRS Publication 5797, Home Energy Tax Credits, is a concise IRS document (Catalog Number 94020W) that summarizes two nonrefundable tax credits for energy-saving home upgrades:
- Energy Efficient Home Improvement Credit (Section 25C)
- Residential Clean Energy Credit (Section 25D)
It covers who qualifies, basic credit percentages, annual limits, and points readers to energy.gov for product requirements. The publication applies to improvements installed from 2022 through 2025.
Key takeaway from Pub 5797: Claim the credit in the tax year the improvement is installed (not just purchased). Credits never apply to homes you don’t use as a residence.
Energy Efficient Home Improvement Credit (Section 25C) – Up to $3,200 Per Year
This credit rewards energy-efficiency upgrades to your home’s “building envelope” and mechanical systems.
Who Qualifies?
- Your main home (where you live most of the year) in the United States.
- Existing homes only (not new construction).
- Owners or renters who pay for the improvements.
- Partial business use allowed with limitations.
Qualifying Improvements (2023–2025)
Must meet strict efficiency standards (ENERGY STAR, CEE highest tier excluding advanced, IECC, etc.) and, for most items, be made by a qualified manufacturer with a Qualified Manufacturer Identification Number (QMID) reported on your return.
Categories and limits (30% of qualified costs):
- Heat pumps, heat pump water heaters, biomass stoves & boilers — Up to $2,000 annual credit
- Central air conditioners, furnaces, boilers, water heaters, electrical panel upgrades (200-amp+) — Up to $600 per item
- Exterior doors — Up to $500 total ($250 per door)
- Exterior windows & skylights — Up to $600 total
- Insulation & air sealing — Part of the $1,200 overall envelope cap
- Home energy audits — Up to $150
Annual cap: $1,200 for most envelope and equipment items + separate $2,000 for heat pumps/biomass = maximum $3,200 per year. No lifetime limit through 2025.
Labor costs count for mechanical systems but not for doors/windows/insulation.
Residential Clean Energy Credit (Section 25D) – 30% with No Dollar Cap
This credit covers clean, renewable energy systems and is one of the most generous home incentives ever offered.
Qualifying Property (Installed 2022–2025)
- Solar electric panels (photovoltaic)
- Solar water heaters (SRCC-certified)
- Small wind turbines
- Geothermal heat pumps (ENERGY STAR)
- Battery storage systems (minimum 3 kWh capacity, starting 2023)
- Fuel cells
- Solar roofing tiles/shingles that generate electricity
Credit amount: 30% of qualified costs (purchase + labor/installation).
No annual or lifetime dollar limit (except fuel cells: $500 per ½ kW capacity).
Excess credit carries forward to future years.
What Costs Qualify?
- Equipment, onsite labor, wiring, piping.
- Excludes: Interest on loans, used equipment, standard roofing materials.
Who Can Claim These Home Energy Tax Credits?
- U.S. residents improving a home they live in (primary or second home, with restrictions).
- Renters who pay for qualifying improvements.
- Not available for landlords who don’t live in the property or purely business-use spaces.
How to Claim the Credits (Step-by-Step)?
- Install the qualifying improvement by December 31, 2025.
- Keep receipts, manufacturer certifications, and QMID (if required).
- Complete Form 5695, Residential Energy Credits:
- Part I → Residential Clean Energy Credit
- Part II → Energy Efficient Home Improvement Credit
- Attach to your Form 1040 and file by the 2026 deadline (or extension).
- The credit is nonrefundable — it reduces tax owed but won’t generate a refund beyond what you owe.
Pro tip: Report the QMID for 2025 claims on qualifying manufactured products.
2026 Status: Credits Have Expired
As confirmed on IRS.gov pages updated in January 2026:
- No new claims for property placed in service after December 31, 2025.
- You can still claim 2025 installations on your 2025 tax return.
- Later phase-downs (26% in 2033, 22% in 2034 for clean energy) no longer apply due to the shortened expiration.
Tips to Maximize Your Savings
- Verify products on energy.gov or qualified manufacturer lists.
- Subtract any rebates or utility subsidies that reduce your cost basis.
- Combine both credits in the same year (they don’t conflict).
- Consult a tax professional or use IRS Free File/Taxpayer Assistance Centers.
- Keep records for at least 3 years.
