- 5 - only if the Secretary has given written notice to the taxpayer 30 days before the levy. Section 6330(a) requires the Secretary to send a written notice to the taxpayer of the amount of the unpaid tax and the taxpayer’s right to a hearing at least 30 days before the Service can collect a tax by levy. At the hearing, the taxpayer may raise challenges to the existence or amount of the underlying tax liability if the person did not receive a notice of deficiency or did not otherwise have an opportunity to dispute the tax liability. Sec. 6330(c)(2)(B). This Court has decided that for purposes of section 6330(c)(2)(B), if a taxpayer signed a Form 4549-CG and waived his right to challenge the proposed assessments, then he is deemed to have had an opportunity to dispute his tax liabilities and is thereby precluded from challenging them. Zapara v. Commissioner, 124 T.C. 223, 228 (2005); Aguirre v. Commissioner, 117 T.C. 324, 327 (2001). Putting aside petitioner’s receiving notices of deficiency and failing to respond, which precludes review by this Court under section 6330(c)(2)(B), he signed the Forms 4549-CG. He thereby explicitly waived his right to contest the existence or the amount of the underlying liabilities in this Court and is deemed to have had a prior opportunity to dispute his liabilities within the meaning of section 6320(c)(2)(B). Accordingly, respondent’s determination is sustained.Page: Previous 1 2 3 4 5 6 7 8 NextLast modified: November 10, 2007
