Home Improvement Tax Credit List

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 Inflation Reduction Act extended these credits through 2032, but the January 2026 expiration of legacy programs 25C and 25D changed which upgrades qualify—and how much you can claim.

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 Energy Efficient Home Improvement Credit caps annual claims at $1,200 for most upgrades, with separate $2,000 limits for heat pumps and biomass stoves. But the Residential Clean Energy Credit applies 30% to total project costs—a $25,000 solar installation returns $7,500 at tax time.

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.

"The Energy Efficient Home Improvement Credit provides a credit equal to 30% of certain qualified expenses" — IRS Energy Efficient Home Improvement 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?

Federal credits return 30% of equipment and installation costs, but annual and lifetime caps vary by upgrade category. 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 Residential Clean Energy Credit operates without annual caps through 2032. 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.

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. Use our free rebate calculator to estimate your specific savings across federal and state programs.

So the maximum single-year federal claim combining Energy Efficient Home Improvement and Residential Clean Energy credits exceeds $15,000 when pairing capped upgrades with uncapped solar or geothermal projects.

What Equipment and Upgrades Qualify for Tax Credits?

ENERGY STAR certification determines eligibility for most Energy Efficient Home Improvement Credit claims. 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 Residential Clean Energy Credit covers broader equipment categories. 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.

So the safest approach involves confirming equipment eligibility through the ENERGY STAR product finder database and reviewing IRS Form 5695 instructions before installation. 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 Residential Clean Energy Credit operates without income restrictions through 2032. 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.

But the Energy Efficient Home Improvement Credit introduced modified adjusted gross income (MAGI) caps starting in 2026. 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.

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. But vacation homes and second residences qualify for Residential Clean Energy credits while remaining ineligible for Energy Efficient Home Improvement credits.

So a married couple earning $180,000 MAGI claims reduced Energy Efficient Home Improvement credits (50% of full amount) but receives full 30% Residential Clean Energy credits on solar installations. 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?

IRS Form 5695 consolidates both Energy Efficient Home Improvement and Residential Clean Energy credits into a single filing document. Part I calculates Residential Clean Energy credits for solar, geothermal, wind, and battery systems. And Part II determines Energy Efficient Home Improvement credits for insulation, windows, doors, and heat pumps.

Taxpayers complete Form 5695 when filing their annual 1040 return—no advance registration required. Attach manufacturer certification statements showing equipment meets efficiency standards. Or keep installation receipts documenting costs, dates, and contractor information for potential IRS verification.

The credit amount from Form 5695 Line 14 transfers to Schedule 3 Line 5, then flows to Form 1040 Line 20 as a nonrefundable credit. 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.

But federal credits stack with state rebates, utility incentives, and local programs without reduction. California homeowners claiming 30% federal credit (currently available through December 2032 under the Inflation Reduction Act)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.

"Energy efficiency incentives available through federal, state, and local programs can significantly reduce the upfront costs" — DSIRE USA Database

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.

Frequently Asked Questions

What home improvement tax credits are available in 2026?

The IRA framework provides two primary federal credits in 2026: the Energy Efficient Home Improvement Credit covering insulation, windows, doors, and HVAC at 30% up to $1,200-$2,000 annual caps, and the Residential Clean Energy Credit offering 30% back on solar, geothermal, wind, and battery storage with no annual limits through 2032. State programs like California's TECH Clean California and New York's EmPower+ add rebates stacking with federal credits.

Are home improvement tax credits still available after the 25C and 25D expiration?

Yes—Sections 25C and 25D expired January 1, 2026, but the IRA extended replacement credits through 2032 under modified rules. The Energy Efficient Home Improvement Credit continues 25C benefits with updated efficiency standards and income caps. And the Residential Clean Energy Credit maintains 25D's 30% rate through 2032 before stepping down to 26% in 2033 and 22% in 2034.

How much can I claim for home improvement tax credits?

Maximum annual claims depend on upgrade type. Energy Efficient Home Improvement credits cap at $1,200 for insulation, windows, and doors combined, with separate $2,000 limits for heat pumps and biomass stoves. But Residential Clean Energy credits have no annual cap—a $30,000 solar installation returns $9,000 regardless of other claimed credits. Combined federal credits can exceed $15,000 when pairing capped and uncapped upgrades in one tax year.

What home improvements qualify for tax credits?

ENERGY STAR certified insulation, windows (climate-specific U-factor), doors (U-factor ≤0.17), heat pumps (HSPF2 ≥9), heat pump water heaters (UEF ≥3.3), and central AC (SEER2 ≥16) qualify for Energy Efficient Home Improvement credits. Solar panels, geothermal systems, wind turbines, and battery storage ≥3kWh claim Residential Clean Energy credits. Traditional furnaces, non-heat-pump water heaters, and appliances don't qualify under 2026 rules.
