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 › § 48B
Gives a tax credit for money a taxpayer puts into certain gasification projects. The credit equals 20% of the qualified investment in a year, or 30% for projects that win a special allocation. Qualified investment is the cost basis of eligible property put in service that year, if the property is built or first used by the taxpayer and is depreciable. The Treasury must create a certification program within 180 days, working with the Energy Department, to decide which projects get credits. The program can award up to $350,000,000 in credits, plus another $250,000,000 for projects that separate and store at least 75% of their carbon dioxide. Certificates can only be issued during the 10-fiscal-year period that starts October 1, 2005. To get an award, a project must show it is financially viable without more federal funding, will share enough information, has a market for its products, will use the identified fuels for at least 90% of its needs when making chemicals, fuels, or electricity, has a competent project team, and meets other published rules. Projects that capture more CO2 get the highest priority. A credit cannot be claimed if the same investment already got a credit under section 48A. The credit can be taken back if a project fails to meet its carbon capture or sequestration commitments. Qualifying gasification project: a project using gasification tech by an eligible entity with some certified investment (up to $650,000,000). Gasification technology: a process that turns coal, petroleum residue, biomass, or similar materials into synthesis gas (mainly carbon monoxide and hydrogen). Eligible property: parts of the project needed for gasification. Biomass: agricultural or plant waste, wood/paper mill byproducts, and forestry products (not commonly recycled paper). Carbon capture capability: plant design that can accommodate CO2 capture equipment. Coal: anthracite, bituminous, subbituminous, lignite, and peat. Eligible entity: a person using the project for domestic gasification in industries like chemicals, fertilizers, glass, steel, petroleum residues, forest products, agriculture (including feedlots and dairies), or transportation fuels. Petroleum residue: the carbonized product from high‑boiling parts of petroleum processing.
