- 11 - portion of an underpayment attributable to reasonable cause. Reasonable reliance on the advice of a tax professional may constitute reasonable cause. Sec. 1.6664-4(b), Income Tax Regs. Petitioners contend that they exercised due care in reporting the advances as loans. Petitioners also contend that they reasonably relied on professional advice and that, as a result, their underpayments were attributable to reasonable cause. Messrs. McCurley and Hall did not unconditionally intend to repay the advances, and they knew or reasonably should have known that there was only a remote possibility that SDI would demand repayment of their advances. As a result, we reject petitioners' contentions and hold that they are liable for the accuracy-related penalties for negligence. Because we have held that the McCurleys did not understate their income in 1992, however, they are not liable for the negligence penalty for that year. B. Section 6661 Addition to Tax for Substantial Understatement Section 6661(a), applicable to the McCurleys' 1988 tax year, provides for an addition to tax equal to 25 percent of the amount of an underpayment attributable to a substantial understatement. See Pallottini v. Commissioner, 90 T.C. 498, 503 (1988). The term "understatement" means the excess of (1) the amount of tax required to be shown on the return over (2) the amount of tax shown on the return, reduced by any rebate.
