- 20 - the issuance of the determination letter. The majority opinion does not disagree with this conclusion. See majority op. n.7. Second, Appeals Office hearings are informal. See Katz v. Commissioner, 115 T.C. 329, 337 (2000); Davis v. Commissioner, 115 T.C. 35, 41 (2000); sec. 301.6330-1(d)(2), Q&A-D6, Proced. & Admin. Regs. There exists no right to subpoena witnesses or documents in connection with a section 6330 Appeals Office hearing. See Roberts v. Commissioner, 118 T.C. 365, 372 (2002) affd. 329 F.3d 1224 (11th Cir. 2003); Nestor v. Commissioner, 118 T.C. 162, 166-167 (2002); Davis v. Commissioner, supra at 41-42; sec. 301.6330-1(d)(2), Q&A-D6, Proced. & Admin. Regs. While taxpayers must raise all pertinent issues at the Appeals Office hearing and make a timely good faith effort to produce evidence in support of those issues, they may be unable to provide sufficient evidence to convince a skeptical Appeals Office employee. This is particularly true where the supporting evidence includes the testimony or documents of uncooperative third parties. In such circumstances the taxpayer may seek to provide additional evidence at the section 6330(d)(1) trial utilizing the Tax Court’s Rule 147 subpoena power or the threat thereof. In such cases, in determining whether the Appeals Office abused its discretion, the taking of additional evidence at trial with respect to a previously raised issue may be appropriate. Robinette v.
