Choice "D" is correct. This position passes the realistic probability standard. Given the facts, the position meets the more-likely-than-not standard; that is, a greater than 50% likelihood that the position, if it is challenged, will be upheld on the position’s merits. Therefore, it is proper for the tax preparer to recommend the position to the client. However, the tax preparer is required to inform the client of all possible penalties that the IRS could collect if the IRS disallows the position and, if upon subsequent appeal by the taxpayer the courts conclude that the taxpayer has not met the more-likely-than-not standard.Choices "c", "a", and "b" are incorrect based on the above explanation.
