-9- 6662(d)(2)(A), and is substantial in the case of an individual if the amount of the understatement for the taxable year exceeds the greater of 10 percent of the tax required to be shown in the return for that taxable year or $5,000, sec. 6662(d)(1)(A). The amount of the understatement is to be reduced by that portion of the understatement which is attributable to (1) “the tax treatment of any item by the taxpayer if there is or was substantial authority for such treatment”, sec. 6662(d)(2)(B)(i), or (2) any item if (a) “the relevant facts affecting the item’s tax treatment are adequately disclosed in the return or in a statement attached to the return”, sec. 6662(d)(2)(B)(ii)(I), and (b) “there is a reasonable basis for the tax treatment of such item by the taxpayer”, sec. 6662(d)(2)(B)(ii)(II). The accuracy-related penalty under section 6662(a) does not apply to any portion of an underpayment if it is shown that there was reasonable cause for, and that the taxpayer acted in good faith with respect to, such portion. Sec. 6664(c)(1). The determination of whether the taxpayer acted with reasonable cause and in good faith depends on the pertinent facts and circumstances, including the taxpayer’s efforts to assess such taxpayer’s proper tax liability, the knowledge and experience of the taxpayer, and the reliance on the advice of a professional, such as an accountant.
