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 › § 48C
Gives a tax credit equal to 30% of the qualified investment a taxpayer puts into a certified advanced energy project in a tax year. "Qualified investment" means the cost basis of eligible equipment the taxpayer puts in service that is part of the certified project, and the Secretary can set a maximum amount for each project. A "qualifying advanced energy project" is one the Secretary certifies that re-equips, expands, or builds an industrial or manufacturing facility to make or recycle things like solar, wind, geothermal, or other renewable energy equipment; fuel cells, microturbines, energy storage, or grid modernization gear; carbon capture or low‑carbon fuels and chemicals; energy conservation technologies; electric and large hybrid vehicles and their parts and charging/refueling infrastructure; or other advanced energy items. It also covers projects that cut greenhouse gas emissions by at least 20% through certain systems, and projects that process, refine, or recycle critical materials. It does not include parts of projects that make products used to refine or blend regular transportation fuel (renewable fuels are allowed). "Eligible property" is necessary, tangible equipment (not buildings or major structural parts) used for the project and eligible for depreciation. The Secretary must set up a program with the Energy Department within 180 days to review applications and certify projects. Under the first program, up to $2,300,000,000 in credits can be allocated. Applications are open for 2 years after the program starts; once an application is accepted, the applicant has 1 year to show they meet the rules, and a certification must lead to the project being placed in service within 3 years or it expires. The Secretary will pick projects that are commercially viable and that score highest on job creation, emissions reductions, innovation, low cost, and quick completion. The Secretary will review allocations after 4 years and can reallocate unused or revoked credits. The Secretary must publicly name applicants and credit amounts when certifying. A second program must also be set up within 180 days with up to $10,000,000,000 in credits, of which no more than $6,000,000,000 may go to projects outside certain designated census tracts that had no prior awards under the first program. For that program, applicants have 2 years after acceptance to meet requirements, and certified projects must be placed in service within 2 years. The credit rate for these allocations is 6% instead of 30% unless the project meets certain prevailing wage and apprenticeship rules, in which case the higher rate applies. Prevailing wage and apprenticeship rules follow similar federal standards and carry penalties if not followed. Credits awarded under this rule cannot also be claimed under sections 48, 48A, 48B, 48E, 45Q, or 45V.
