The clean vehicle credit income limits: The §30D clean vehicle credit is subject to income limits: $150,000 (single) / $300,000 (MFJ) for new vehicles; $75,000 (single) / $150,000 (MFJ) for used vehicles. Taxpayers above these limits cannot claim the credit. Additionally, the vehicle must meet price caps: $80,000 for SUVs, vans, and trucks; $55,000 for other vehicles.
Residential Clean Energy Credit — Planning Strategies
| §25D Credit Item | 2026 Amount | Qualifying Property | Carryforward |
|---|---|---|---|
| Solar panels | 30% of cost | Photovoltaic panels; solar water heaters | Yes; carry to future years |
| Wind turbines | 30% of cost | Small wind energy property | Yes |
| Geothermal heat pumps | 30% of cost | Geothermal heat pump property | Yes |
| Battery storage | 30% of cost | Battery storage technology (≥3 kWh) | Yes |
| Fuel cells | 30% of cost; max $500/0.5 kW | Fuel cell property | Yes |

The battery storage credit: Starting in 2023, standalone battery storage systems (not connected to solar panels) qualify for the 30% residential clean energy credit. This is a significant expansion — previously, battery storage only qualified if connected to solar panels. Homeowners who want to add battery storage to an existing solar system can now claim the 30% credit on the battery cost alone.
Energy Efficient Home Improvement Credit (§25C)
| §25C Credit Category | Annual Cap | Per-Item Cap | Qualifying Property |
|---|---|---|---|
| Overall annual cap | $1,200 | N/A | All qualifying improvements combined |
| Heat pumps / heat pump water heaters | $2,000 (separate cap) | N/A | Air source heat pumps; heat pump water heaters |
| Insulation and air sealing | $1,200 (within overall cap) | N/A | Insulation materials; air sealing materials |
| Windows and skylights | $600 (within overall cap) | $600 per item | ENERGY STAR certified windows |
| Exterior doors | $500 (within overall cap) | $250 per door | ENERGY STAR certified doors |
| Home energy audits | $150 (within overall cap) | N/A | Qualified home energy audits |
Source: IRC §25C; IRA §13301
Homeowners can claim both the §25C energy efficient home improvement credit and the §25D residential clean energy credit in the same year. For example, a homeowner who installs solar panels ($30,000 × 30% = $9,000 §25D credit) and a heat pump ($10,000 × 30% = $3,000 §25C credit, up to the $2,000 heat pump cap) can claim $11,000 in total credits. Practitioners should advise clients to plan their home energy improvements to maximize both credits.

Practitioner Planning Checklist — IRA 2022 Tax Credits
- Verify clean vehicle credit eligibility before client purchases. The new clean vehicle credit ($7,500) has strict requirements: vehicle MSRP limits ($80,000 SUV/truck, $55,000 other), battery component sourcing requirements, and income phase-outs ($150,000 single / $300,000 MFJ). Verify all requirements before advising clients.
- Advise clients on the used clean vehicle credit. The used EV credit (up to $4,000 or 30% of purchase price) has lower income limits ($75,000 single / $150,000 MFJ) and applies only to vehicles sold by dealers. This is a significant opportunity for middle-income clients.
- Stack energy efficiency credits for home improvement projects. The energy efficient home improvement credit ($1,200/year aggregate) can be stacked across multiple years. Advise clients to spread large projects (windows, insulation, HVAC) across multiple tax years to maximize the annual $1,200 limit.
- Review the residential clean energy credit for solar installations. The 30% credit for solar, wind, and battery storage installations has no dollar cap. A $30,000 solar installation generates a $9,000 federal tax credit. Advise clients planning home improvements to prioritize solar.
- Advise business clients on commercial clean vehicle credits. Businesses purchasing electric vehicles for commercial use can claim credits up to $40,000 per vehicle (for vehicles over 14,000 lbs). This is separate from the personal clean vehicle credit.
- Monitor IRS enforcement activity for high-income clients. The IRA allocated $80B to IRS enforcement (partially rescinded by subsequent legislation). The IRS has stated it will focus additional resources on taxpayers with income above $400,000. Advise high-income clients to ensure documentation is complete.
