United States v. Home Concrete & Supply

Docket No., 11-139

Argument Date: Tuesday, January 17, 2012

Questions Presented

As a general matter, the Internal Revenue Service (IRS) has three years to assess additional tax if the agency believes that the taxpayer's return has understated the amount of tax owed. 26 U.S.C. 6501(a). That period is extended to six years, however, if the taxpayer "omits from gross income an amount properly includible therein which is in excess of 25 percent of the amount of gross income stated in the [taxpayer's] return." 26 U.S.C. 6501(e)(1)(A).

The questions presented are as follows:

1. Whether an understatement of gross income attributable to an overstatement of basis in sold property is an "omi[ssion] from gross income" that can trigger the extended six-year assessment period.

2. Whether a final regulation promulgated by the Department of the Treasury, which reflects the IRS's view that an understatement of gross income attributable to an overstatement of basis can trigger the extended six-year assessment period, is entitled to judicial deference.
