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 › § 48B
Businesses that invested in gasification projects — plants that convert coal, petroleum residue, biomass, or similar materials into synthesis gas — could claim a tax credit equal to 20 percent of their qualified investment, or 30 percent for credits allocated in the carbon-sequestration round. Projects had to be certified under a program run by the IRS with the Department of Energy, capped at $350 million in total credits plus $250 million more for projects that separate and sequester at least 75 percent of their carbon dioxide emissions. No single project could have more than $650,000,000 of investment certified. Applicants had to show the project was financially viable on its own, had customers lined up, and would get at least 90 percent of its fuel from the sources identified for the project. Highest priority went to projects capturing the most carbon dioxide. Certificates could be issued only during the 10-fiscal-year period that began October 1, 2005, so that window has closed and no new projects can be certified. A credit can be recaptured if a project fails to keep its required carbon separation and sequestration levels, and no credit is allowed for investment already claimed under the section 48A coal project credit.
