The tax credit structures for residential and commercial energy storage systems differ significantly in their phaseout schedules and regulatory frameworks:
Residential Systems (Section 25D Credit)
- Credit rate: 30% of costs through 2032, phasing down to 26% (2033) and 22% (2034).
- Standalone eligibility: Energy storage systems ≥3 kWh qualify independently of solar pairing under Inflation Reduction Act updates.
- Application: Available for primary residences and second homes (rentals excluded).
Commercial Systems (Section 48E ITC)
- Credit structure: Technology-neutral credit for storage projects placed in service after 2024, with a base rate of 6% or bonus rate of 30% if meeting wage/apprenticeship requirements.
- Phaseout tied to emissions reductions (no explicit rate phaseout mentioned in available materials; credits apply through at least 2033 under current IRA provisions).
- Scope: Applies to standalone storage and hybrid systems meeting Section 48 technical standards.
Key Differences
| Aspect | Residential (25D) | Commercial (48E) |
|---|---|---|
| Credit Rate | 30%→26%→22% (2022-2034) | 6%/30% depending on labor standards |
| Eligibility | ≥3 kWh storage, no solar required | No capacity minimum specified |
| Property Type | Primary/secondary residences only | No residential restrictions |
| Sunset | Unavailable after 2034 | At least through 2033 |
Commercial systems gain flexibility through stackable credits and bonus rates for labor compliance, while residential credits focus on straightforward percentage reductions tied to installation dates.
