The federal government cut $8,000 checks to homeowners who installed heat pumps in 2025. And that program just got bigger. The federal home energy tax credits (Sections 25C and 25D) ended for projects completed after December 31, 2025 (IRS FS-2025-05). Federal tax credits for this work have ended, but state, local and utility rebates may still apply; check what is available at your address with the DuloCore rebate calculator.
What Is the Home Improvement Tax Credit for 2026 and How Much Can You Save?
The federal home energy tax credits (Sections 25C and 25D) ended for projects completed after December 31, 2025 (IRS FS-2025-05). The federal Energy Efficient Home Improvement Credit (Section 25C) ended for property placed in service after December 31, 2025 (IRS FS-2025-05). Equipment-specific caps limit heat pump credits to $2,000 and window/door credits to $600 per item category.
Congress replaced the old Section 25C credit with the broader IRA framework in 2023. But 2026 marks the first year the program operates with zero sunset risk through the end of the decade. And the 30% rate stays fixed until 2033, when it drops to 26%.
So homeowners who delayed projects in 2024 and 2025 now face a nine-year window of stable federal support. The average qualifying heat pump installation costs $12,000, generating a $2,000 federal tax credit plus state and utility rebates that stack on top.
Which Home Improvements Qualify for the 2026 Tax Credit?
The IRS qualifies air-source heat pumps, geothermal heat pumps, insulation, air sealing, electric panels, biomass stoves, central air conditioning, and natural gas furnaces for the 2026 credit. Heat pumps carry the highest per-item cap at $2,000. Insulation and air sealing share a combined $1,200 limit. Windows and doors split a $600 cap across all units purchased in the same tax year.
Energy Star certification determines equipment eligibility. And the manufacturer's certification statement must accompany the tax filing. The IRS publishes a qualifying equipment database that updates quarterly with new model numbers.
But geothermal systems operate under separate rules with no dollar caps. Homeowners claim 30% of total installation costs, including drilling, excavation, and equipment. A $30,000 geothermal installation generates a $9,000 federal credit. Learn more about geothermal tax credit rules and stacking opportunities.
What Are the Income Limits and Credit Caps for 2026?
The 2026 Home Energy Tax Credit imposes zero income limits. Households earning $50,000 or $500,000 claim identical credit amounts based on equipment costs. The annual cap restricts total credits to $3,200 per household across all qualifying improvements installed in the same calendar year. Equipment-specific caps apply within that ceiling.
Or homeowners split projects across multiple tax years to maximize total credits. Installing windows in 2026 and a heat pump in 2027 generates $2,600 in federal credits versus $2,000 if completed in one year due to the annual cap.
So strategic timing increases total federal support. And the nine-year program window through 2032 allows multi-year planning. Compare your energy tax credits across state, federal, and utility programs using equipment-specific eligibility rules.
How Do You Claim the Tax Credit on Your 2026 Return?
Form 5695 only covers qualifying work completed by December 31, 2025 and claimed on a 2025 return; the federal 25C and 25D credits ended after that date (IRS FS-2025-05). The form requires manufacturer certification statements, total equipment costs, and installation dates. The credit reduces tax liability dollar-for-dollar but doesn't generate refunds for amounts exceeding taxes owed.
Keep all receipts, invoices, and manufacturer certification statements for three years after filing. And the IRS audits energy credits at higher rates than standard deductions. Use our free rebate calculator to estimate your total federal, state, and utility incentives before starting a project.
When Does the 2026 Tax Credit Start and End?
The 2026 Home Energy Tax Credit covers equipment installed between January 1, 2026 and December 31, 2026. Homeowners claim credits when filing 2026 federal tax returns in early 2027. The broader IRA program runs through December 31, 2032, maintaining 30% credit rates through 2032 before stepping down to 26% in 2033 and 22% in 2034.
But installation dates determine eligibility, not purchase dates. Equipment ordered in 2025 but installed in January 2026 qualifies for the 2026 credit. And partial installations don't qualify until the entire system operates.
So contractors who start work in December 2025 but complete commissioning in January 2026 generate 2026 credits, not 2025 credits. The IRS defines "placed in service" as the date equipment begins operating in its intended capacity.
Can You Stack Multiple Tax Credits on the Same Project?
A $12,000 heat pump generating a $2,000 federal credit plus a $2,500 state rebate delivers $4,500 in total incentives.
Or homeowners combine the Home Energy Credit with separate federal programs on different project components. Installing a heat pump with an EV charger triggers two distinct federal credits under different IRS sections. Check heat pump rebates for state-specific stacking rules and program combinations.
And income-qualified households access enhanced rebates through the DOE Home Efficiency Rebate Program separate from tax credits. Households earning below 150% of area median income claim point-of-sale rebates up to $8,000 for heat pumps plus separate federal tax credits on the same equipment.
| Program | 2026 Amount | Income Limit | Application Deadline |

| DOE Home Efficiency Rebates | Up to $8,000 for heat pumps | 150% AMI | Varies by state |
| State Heat Pump Rebates | $500-$5,000 | Varies by state | Rolling, funds limited |

Frequently Asked Questions
What home improvement tax credits are available in 2026?
The federal Energy Efficient Home Improvement Credit (Section 25C) ended for property placed in service after December 31, 2025 (IRS FS-2025-05). Heat pumps qualify for $2,000 maximum per unit. Geothermal systems claim 30% of total costs with no dollar cap. All equipment requires Energy Star certification and installation between January 1, 2026 and December 31, 2032.
Are home improvement tax credits still available after December 2025?
The federal home energy tax credits (Sections 25C and 25D) ended for projects completed after December 31, 2025 (IRS FS-2025-05). The old Section 25C and 25D credits expired December 31, 2025 and were replaced by the current framework with identical 30% rates but higher annual caps and expanded equipment lists. So 2026 homeowners access more generous credits than previous years.
How much can you claim for home improvement tax credits in 2026?
Homeowners claim up to $3,200 per year across all qualifying improvements. Heat pumps max out at $2,000 per unit. Insulation and air sealing share a $1,200 combined limit. Windows and exterior doors split a $600 cap. Geothermal heat pumps claim 30% of unlimited total project costs. Credits carry forward to future tax years if they exceed current tax liability.
What home improvements qualify for tax credits in 2026?
Energy Star certified heat pumps, central AC, natural gas furnaces, biomass stoves, insulation, air sealing, windows, doors, electric panels, and geothermal systems qualify. Equipment must meet efficiency thresholds published in the Energy Star federal tax credit database. Non-certified equipment from the same manufacturer doesn't qualify even if similar models appear on the list.
Do you need receipts for home improvement tax credits in 2026?
Form 5695 only covers qualifying work completed by December 31, 2025 and claimed on a 2025 return; the federal 25C and 25D credits ended after that date (IRS FS-2025-05). Keep receipts showing equipment costs, labor charges, installation dates, and contractor details for three years after filing. And product certification statements must include manufacturer name, equipment model number, and Energy Star certification confirmation. Missing documentation disqualifies credits during audits.
