This bill proposes to amend the Internal Revenue Code of 1986 by establishing a new Chapter 50B, which imposes a 100 percent tax on specific settlement fund payments. The legislation targets any amount received by a taxpayer from a fund created as a result of a civil action initiated by the President of the United States against the Internal Revenue Service. This measure effectively recaptures the entirety of such payments for the government. Furthermore, the bill stipulates that these qualified settlement fund payments are to be excluded from a taxpayer's gross income for general income tax purposes. However, the 100 percent tax imposed on these payments under the new chapter is explicitly made non-deductible from income tax. These provisions apply to amounts received after the bill's enactment, ensuring immediate effect on any future qualifying settlements.
