Knappe v. United States, No. 10-56904 (9th Cir. 2013)Annotate this Case
Acting on the bad advice of his accountant, plaintiff, the executor of an estate, filed the estate-tax return several months late. Consequently, the IRS assessed significant penalties against the estate. Plaintiff initiated this action seeking a refund of the penalty. The court concluded that it was plaintiff's duty to ascertain the correct extended filing deadline. By relying on his accountant's advice about that nonsubstantive matter, he failed to exercise ordinary business care and prudence, and he could not show reasonable cause to excuse the penalty. Therefore, the court affirmed the judgment of the district court.
