Energy Efficiency Credits: What Homeowners Can Claim

Federal energy tax credits for homeowners: Section 25C ($3,200/year), 25D (30% solar), and 30D (EV credits). Eligible upgrades and dollar amounts.

If you are a homeowner planning energy-efficient upgrades --- from insulation and heat pumps to solar panels and EV chargers --- the federal government offers substantial energy tax credits that directly reduce your tax bill. This guide covers the three main credits, their dollar limits, and how to claim them.

Key Takeaways

  • The Section 25C credit covers up to $3,200 per year for home efficiency upgrades.
  • The Section 25D credit covers 30% of solar and clean energy costs with no annual cap through 2032.
  • The Section 30D credit provides up to $7,500 for qualifying electric vehicles.
  • All three credits are nonrefundable but the 25D credit carries forward to future years.

Quick Comparison: 25C vs 25D vs 30D

Which energy credit applies?
Credit What It Covers Max Benefit Residence Rules Carryforward?
25C Home Improvement Efficiency upgrades (heat pumps, windows, insulation) Up to $3,200 per year Primary residence only No
25D Clean Energy Solar, battery storage, geothermal, wind 30% of cost, no annual cap Primary + secondary homes Yes
30D/25E Clean Vehicle New or used EVs meeting sourcing and MSRP rules Up to $7,500 (new) or $4,000 (used) Vehicle and income limits apply No

Section 25C: Energy Efficient Home Improvement Credit

This credit covers common home efficiency upgrades. It resets annually, so you can claim it every year you make qualifying improvements.

Annual limits (2025 and 2026):

Section 25C annual limits
Category Credit Amount Annual Cap
Heat pumps, heat pump water heaters, biomass stoves 30% of cost $2,000
Windows and skylights 30% of cost $600
Exterior doors 30% of cost $250 per door ($500 total)
Insulation, air sealing materials 30% of cost Part of $1,200 overall cap
Central A/C, gas furnaces, water heaters 30% of cost Part of $1,200 overall cap
Home energy audit 30% of cost $150
Overall annual maximum $3,200

The overall structure is: up to $1,200 for most improvements, plus up to $2,000 for heat pumps and biomass stoves, for a combined maximum of $3,200 per year.

Eligibility notes:

  • Products must meet specific energy-efficiency standards. Check the ENERGY STAR website for a list of qualifying products.
  • Labor costs for installation are included for most items (except windows, doors, and insulation where only product costs qualify).
  • Available for your primary residence only.

Section 25D: Residential Clean Energy Credit

This credit covers larger clean-energy installations and has no annual dollar cap --- you get 30% of the total cost.

Credit rate schedule:

Year Placed in ServiceCredit Rate
2022 through 203230%
203326%
203422%
After 2034Expires (unless extended)

Qualifying systems:

  • Solar electric (photovoltaic) panels
  • Solar water heaters
  • Small wind turbines
  • Geothermal heat pumps
  • Battery storage systems (3 kWh minimum capacity)
  • Fuel cell systems

Example: A $25,000 solar panel installation placed in service in 2025 or 2026 qualifies for a $7,500 credit (30% x $25,000). If your tax liability is only $5,000 that year, the remaining $2,500 carries forward to future years.

Section 30D: Clean Vehicle Credit

The EV tax credit provides up to $7,500 for qualifying new electric vehicles and up to $4,000 for qualifying used EVs (Section 25E).

Key requirements (2025-2026):

  • Vehicle must be assembled in North America.
  • Battery mineral and component sourcing requirements apply (split into two $3,750 portions).
  • Income limits: $150,000 MAGI (single) or $300,000 (married filing jointly) for new vehicles.
  • MSRP limits: $55,000 for cars, $80,000 for SUVs, trucks, and vans.

Starting in 2024, buyers can transfer the credit to the dealer at the point of sale for an instant price reduction instead of waiting to claim it on their tax return.

Documentation Tips

Save these records for every energy credit you claim:

  • Invoices and receipts showing the product description, cost, and date of purchase.
  • Manufacturer certification statements confirming the product meets IRS energy-efficiency standards.
  • Proof of payment (credit card statement, cancelled check, or bank record).
  • Form 5695 --- this is the form you file to claim both the 25C and 25D credits.

Keep records for at least three years after filing. If you carry forward unused 25D credits, keep records until the credit is fully used.

Common Mistakes to Avoid

  • Claiming credits on a second home. The 25C credit applies only to your primary residence. The 25D credit applies to primary and secondary residences (but not rental properties).
  • Missing the efficiency standards. Not every heat pump or window qualifies. Verify the product meets the required efficiency rating before purchase.
  • Forgetting the annual reset. The 25C credit resets each year. If you did not max it out last year, you cannot carry forward unused capacity --- but you can claim new improvements this year.

Forms to File

  • Form 5695 is used to claim both residential energy credits (Parts I and II).
  • The credit flows to your Form 1040, Schedule 3, Line 5.
