- 13 - and may only be reduced by reason of substantial authority if the taxpayer reasonably believed that the tax treatment of the tax shelter item was more likely than not the proper treatment. Sec. 6661(b)(2)(C). Petitioners do not argue that substantial authority exists for their tax treatment of the items in issue or that they adequately disclosed the relevant facts with respect to the Barrister partnership investment. Rather, they contend that respondent should have waived the additions to tax pursuant to section 6661(c). Section 6661(c) authorizes respondent to waive any part of the addition to tax imposed under section 6661(a) upon a showing by the taxpayer of reasonable cause for the understatement and that the taxpayer acted in good faith. The most important factor in determining whether to grant a waiver is the extent of the taxpayer's effort to assess the taxpayer's proper tax liability under the law. Mailman v. Commissioner, 91 T.C. 1079, 1083-1084 (1988); sec. 1.6661-6(b), Income Tax Regs. Reliance upon the advice of a professional will not constitute reasonable cause and good faith, unless under all the circumstances, such reliance was reasonable. Sec. 1.6661-6(b), Income Tax Regs. The appropriate standard of review for denial of a waiver is whether respondent's refusal to waive the section 6661 addition to tax constitutes an abuse of discretion. Mailman v. Commissioner, supra at 1083- 1084.Page: Previous 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 Next
