9064 / What are the penalties if a taxpayer overvalues property donated to charity?

If a taxpayer underpays his tax because of a substantial valuation misstatement of property donated to charity, the taxpayer may be subject to a penalty of 20 percent of the underpayment attributable to the misstatement.¹ However, this penalty applies only if the underpayment attributable to the misstatement exceeds $5,000 ($10,000 for a corporation other than an S corporation or a personal holding company).² A “substantial valuation misstatement” exists if the value claimed is 150 percent or more of the amount determined to be correct.³ If the value claimed is 200 percent or more of the amount determined to be correct, there is a “gross valuation misstatement,” which is subject to a 40 percent underpayment penalty.⁴
