Title 26 › Subtitle 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
Gives a tax credit equal to a percentage of the money you spend to build certain electricity-generating projects and energy storage. The normal credit rate is 6 percent of the qualified investment. Smaller projects (under 1 megawatt), projects that start construction early (before 60 days after the Treasury issues guidance), or projects that meet certain workforce or other rules can qualify for higher rates. If a project is placed in an "energy community," the credit rate goes up by either 2 percentage points or 10 percentage points depending on which size or start-date category it fits. Fuel cell property has a special flat 30 percent rule. There are also rules that set an “adjusted percentage” used for some bonus parts of the credit based on when construction begins: 40 percent (20 percent for offshore wind) if before June 16, 2025; 45 percent (27.5 percent) if between June 16, 2025 and December 31, 2025; 50 percent (35 percent) if in calendar year 2026; and 55 percent if construction begins after December 31, 2026. A qualified investment is mainly the cost basis of the equipment put in service and, for small facilities (up to 5 megawatts), certain interconnection costs. A qualified facility must generate electricity, be placed in service after December 31, 2024, and have an anticipated greenhouse gas emissions rate of no more than zero. The credit cannot be claimed for facilities already getting certain other federal credits (like renewable electricity, advanced nuclear, carbon sequestration, zero-emission nuclear, the clean electricity production credit, the Section 48 energy credit, or qualifying advanced coal credits). Projects that get material help from a prohibited foreign entity after December 31, 2025 are ineligible. Credits phase down by construction-start year relative to an “applicable year” (100 percent in the first year, 75 percent in the second, 50 percent in the third, and 0 percent thereafter). Wind and solar projects lose eligibility for this credit for property placed in service after December 31, 2027. There is a limited environmental-justice allocation program (starting January 1, 2025) that can raise the credit by 10 or 20 percentage points for certain small, low-income, or Indian-land projects; the program has a 1.8 gigawatt direct-current per-year capacity limit and rules for allocation and recapture. The Treasury must issue guidance by January 1, 2025.
