Title 26 › Subtitle A — Income Taxes › CHAPTER 1 — NORMAL TAXES AND SURTAXES › Subchapter A — Determination of Tax Liability › PART IV — CREDITS AGAINST TAX › Subpart E — Rules for Computing Investment Credit › § 48E
Offers a tax credit equal to a percentage of the money a taxpayer spends to put clean electricity facilities or energy storage into service. The normal credit rate is 6 percent. A higher 30 percent rate can apply for small projects (under 1 megawatt), for projects that started before certain Treasury guidance, or for projects that meet special labor, apprenticeship, and domestic-content rules. Projects in “energy communities” get an extra boost: +2 percentage points for the 6% cases and +10 points for the 30% cases. The domestic-content bonus uses set percentages based on when construction begins: 40% (20% for offshore wind) before June 16, 2025; 45% (27.5% offshore) for mid‑June through 2025; 50% (35% offshore) in calendar year 2026; and 55% after December 31, 2026. Qualified investment is the cost basis of the property placed in service (including certain interconnection costs for small facilities). Qualified property is tangible, depreciable equipment used in the facility and must be built or first used by the taxpayer. A qualified facility must generate electricity, be placed in service after December 31, 2024, and have a greenhouse‑gas emissions rate of zero; some facilities are excluded if they already get certain other tax credits (sections 45, 45J, 45Q, 45U, 45Y, 48, or 48A). No credit is allowed for projects whose construction after December 31, 2025 includes material assistance from prohibited foreign entities. The credit phases out by a schedule tied to an “applicable year” (100%, 75%, 50%, then 0%). Wind and solar facilities lose the credit for property placed in service after December 31, 2027 (storage at those sites is still allowed). Prevailing wage and apprenticeship rules apply. The Treasury must set rules and an environmental‑justice allocation program (1.8 gigawatts DC per year starting January 1, 2025). Credits can be recaptured if a facility’s emissions are found to exceed 10 grams CO2e per kWh. Guidance is required by January 1, 2025.
