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
| 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):
| 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 Service | Credit Rate |
|---|---|
| 2022 through 2032 | 30% |
| 2033 | 26% |
| 2034 | 22% |
| After 2034 | Expires (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.
