- 11 - Petitioner received a notice of deficiency for the tax year 1999 and thus may not dispute the underlying deficiency for that year.4 For the remaining tax years, petitioner had the opportunity at the section 6320 hearing to challenge the underlying tax liabilities but did not. “This statutory preclusion is triggered by the opportunity to contest the underlying liability, even if the opportunity is not pursued.” Bell v. Commissioner, 126 T.C. 356, 358 (2006); Goza v. Commissioner, supra at 182-183. Accordingly, we review respondent’s determination for abuse of discretion. Section 6159 authorizes the Secretary to enter into a written installment agreement with a taxpayer if such an agreement will facilitate the full or partial collection of the tax liability. Section 7122(a) permits the Secretary to compromise tax liabilities. Section 7122(c) requires the Secretary to prescribe guidelines for evaluating offers in compromise and to “develop and publish schedules of national and local allowances designed to provide that taxpayers entering into a compromise have an adequate means to provide for basic living expenses.” Sec. 7122(c)(1) and (2)(A). 4 Furthermore, petitioner already petitioned this Court for redetermination of the deficiency for 1999. As mentioned supra p. 3, that case resulted in a stipulated decision, and respondent assessed the deficiency stipulated in that decision.Page: Previous 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 NextLast modified: March 27, 2008
