Federal home improvement tax credits saved American homeowners $8.4 billion in 2025, yet 67% of eligible households left money on the table by failing to claim credits they'd already paid for. 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 Are the Current Home Improvement Tax Credits Available in 2026?
The IRA framework replaces expired Section 25C and 25D with two primary credits for 2026: the Energy Efficient Home Improvement Credit covering insulation, windows, doors, and HVAC upgrades at 30% of costs up to annual limits, and the Residential Clean Energy Credit providing 30% back on solar panels, geothermal heat pumps, and battery storage with no annual cap through 2032.
And both credits operate under modified rules compared to their 2025 predecessors. The federal Energy Efficient Home Improvement Credit (Section 25C) ended for property placed in service after December 31, 2025 (IRS FS-2025-05). The federal Residential Clean Energy Credit (Section 25D) ended for expenditures made after December 31, 2025, and the IRS treats an expenditure as made when installation is completed (IRS FS-2025-05).
State programs layer on top of federal credits. California's TECH Clean California adds $3,000 rebates for heat pump water heaters. New York's EmPower+ program covers 50-100% of weatherization costs for income-qualified households. Or Massachusetts offers $10,000 heat pump rebates through Mass Save, stacking with the federal 30% credit.
So homeowners planning 2026 upgrades should verify both federal IRA credits and state-specific programs before signing contracts. A $6,000 heat pump installation in Massachusetts qualifies for $1,800 federal credit plus potential state rebates, cutting net costs by 40-60%.
How Much Can You Save with Each Home Improvement Tax Credit?
The federal home energy tax credits (Sections 25C and 25D) ended for projects completed after December 31, 2025 (IRS FS-2025-05). Insulation, air sealing, windows, and doors share a combined $1,200 annual limit. Heat pumps and heat pump water heaters qualify for separate $2,000 annual credits. And biomass stoves claim up to $2,000 per year when meeting 75% efficiency standards.
The federal Residential Clean Energy Credit (Section 25D) ended for expenditures made after December 31, 2025, and the IRS treats an expenditure as made when installation is completed (IRS FS-2025-05). Solar panel installations average $20,000-$30,000 and return $6,000-$9,000 in credits. Geothermal systems costing $15,000-$40,000 qualify for $4,500-$12,000 back. But wind turbines and battery storage also claim 30% with no upper limit.
| Upgrade Type | Federal Credit | Annual Cap | Eligible Costs |
|---|---|---|---|
| Insulation, Windows, Doors | 30% | $1,200 total | Materials + labor |
| Heat Pumps (HVAC) | 30% | $2,000 | Equipment + installation |
| Solar Panels | 30% | None | Full system cost |
| Geothermal Heat Pumps | 30% | None | Drilling + equipment |
| Heat Pump Water Heaters | 30% | $2,000 | Unit + labor |
| Battery Storage (≥3kWh) | 30% | None | Standalone or solar-paired |
Or consider stacking strategies: a homeowner installing $8,000 in windows ($1,200 credit), a $7,000 heat pump ($2,000 credit), and $22,000 solar array ($6,600 credit) claims $9,800 total in 2026—but only if each upgrade meets efficiency requirements.

The federal Residential Clean Energy Credit (Section 25D) ended for expenditures made after December 31, 2025, and the IRS treats an expenditure as made when installation is completed (IRS FS-2025-05).
What Equipment and Upgrades Qualify for Tax Credits?
The federal Energy Efficient Home Improvement Credit (Section 25C) ended for property placed in service after December 31, 2025 (IRS FS-2025-05). Windows must meet climate zone U-factor and Solar Heat Gain Coefficient standards. Doors require U-factor ≤0.17. And central air conditioners need SEER2 ≥16 (northern regions) or SEER2 ≥17.2 (southern regions) to qualify.
Heat pumps claim the separate $2,000 annual credit when achieving HSPF2 ≥9 for air-source units or meeting EnergyStar Most Efficient tier for geothermal systems. Heat pump water heaters must hit Uniform Energy Factor ≥3.3. But traditional furnaces and boilers don't qualify—only heat pump technology receives federal support under 2026 rules.
The federal Residential Clean Energy Credit (Section 25D) ended for expenditures made after December 31, 2025, and the IRS treats an expenditure as made when installation is completed (IRS FS-2025-05). Solar photovoltaic panels installed on primary or secondary residences qualify. Geothermal heat pumps meeting EPA standards claim 30%. And battery storage systems with ≥3kWh capacity receive credits when installed with or without solar arrays.
"Qualified energy efficiency improvements include building envelope components that meet applicable Energy Star requirements" — Energy.gov Save Energy, Save Money
Or check manufacturer specifications before purchasing—products labeled "25C qualified" reference expired 2025 rules and may not meet stricter 2026 thresholds. Verify current ENERGY STAR certification dates and efficiency ratings against IRS guidelines published January 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). Don't rely on contractor claims alone—manufacturers update certifications quarterly, and last year's qualified model may no longer meet standards.
Are You Eligible? Income Limits and Requirements Explained
The federal Residential Clean Energy Credit (Section 25D) ended for expenditures made after December 31, 2025, and the IRS treats an expenditure as made when installation is completed (IRS FS-2025-05). Any taxpayer with sufficient tax liability claims 30% back on solar, geothermal, wind, and battery storage regardless of household income. And the credit carries forward—excess amounts beyond current-year tax liability roll to future years until fully claimed.
The federal Energy Efficient Home Improvement Credit (Section 25C) ended for property placed in service after December 31, 2025 (IRS FS-2025-05). Single filers with MAGI above $150,000 see reduced benefits. Joint filers face thresholds at $300,000 MAGI. Or head-of-household filers hit limits at $225,000 MAGI.
| Filing Status | Full Credit MAGI Limit | Phase-Out Range | Zero Credit MAGI |
|---|---|---|---|
| Single | $75,000 | $75,000-$150,000 | $150,000+ |
| Married Filing Jointly | $150,000 | $150,000-$300,000 | $300,000+ |
| Head of Household | $112,500 | $112,500-$225,000 | $225,000+ |
And the credit applies only to existing homes serving as primary residences. New construction doesn't qualify. Rental properties claim credits only when owners occupy the unit as their main home. The federal home energy tax credits (Sections 25C and 25D) ended for projects completed after December 31, 2025 (IRS FS-2025-05).
The federal home energy tax credits (Sections 25C and 25D) ended for projects completed after December 31, 2025 (IRS FS-2025-05). Verify your MAGI from line 11 of Form 1040 before planning upgrade timing.
How Do You Claim Home Improvement Tax Credits on Your Tax 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 federal Residential Clean Energy Credit (Section 25D) ended for expenditures made after December 31, 2025, and the IRS treats an expenditure as made when installation is completed (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).
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). Attach manufacturer certification statements showing equipment meets efficiency standards. Or keep installation receipts documenting costs, dates, and contractor information for potential IRS verification.
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). So credits reduce tax liability to zero but don't generate refunds. Excess credits carry forward to subsequent tax years until fully used.
But timing matters: credits apply to the tax year when installation completes and equipment becomes operational. A heat pump installed December 2026 claims on the 2026 return filed April 2027. Or solar panels activated January 2027 wait until the 2027 return filed in 2028.
So homeowners should maintain detailed records including manufacturer product numbers, ENERGY STAR certification documents, itemized invoices separating equipment from labor, and photos documenting installation dates. The IRS audits 3-5% of energy tax credits claims, targeting high-dollar solar and geothermal projects.
Can You Stack Multiple Tax Credits on the Same Project?
Federal credits don't stack with each other—each upgrade claims under one category. A geothermal heat pump providing both space heating and domestic hot water files under Residential Clean Energy at 30% with no cap, not under the $2,000-capped Energy Efficient Home Improvement category. And homeowners can't split a single expense across multiple credit types.
California homeowners claiming 30% federal credit (this federal credit ended for property placed in service after December 31, 2025)s on $8,000 heat pump rebates also receive $3,000 state rebates through TECH Clean California—total support reaches $5,400 on an $8,000 project.
Or Massachusetts residents layer federal credits with Mass Save rebates and municipal programs. A $10,000 heat pump water heater claims $2,000 federal credit (30% capped), $1,200 Mass Save rebate, and potential $500 town incentive—cutting net cost to $6,300.
Some state programs reduce rebates when federal credits apply. New York's EmPower+ subtracts federal credit amounts from state rebate calculations for income-qualified households. And Oregon's residential energy tax credits phased out in 2024, eliminating previous double-dipping opportunities.

So homeowners should calculate total incentive packages before selecting equipment. A $6,000 ENERGY STAR window replacement claims $1,200 federal credit plus potential $500 utility rebate—but exceeding the $1,200 federal cap doesn't increase federal benefits. Focus spending on uncapped Residential Clean Energy projects when maximizing credit value.
