421.28  Exceptions to successor liability.
  The immediate successor to a licensee’s or retailer’s business or stock of goods under chapter 423A or 423B, or section 423.33 or 452A.65, is not personally liable for the amount of delinquent tax, interest, or penalty due and unpaid if the immediate successor shows that the purchase of the business or stock of goods was made in good faith that no delinquent tax, interest, or penalty was due and unpaid. For purposes of this section the immediate successor shows good faith by evidence that the department had provided the immediate successor with a certified statement that no delinquent tax, interest, or penalty is unpaid, or that the immediate successor had taken in good faith a certified statement from the licensee, retailer, or seller that no delinquent tax, interest, or penalty is unpaid. When requested to do so by a person with whom the licensee or retailer is negotiating the sale of the business or stock of goods, the director of revenue shall, upon being satisfied that such a situation exists, inform that person as to the amount of unpaid delinquent tax, interest, or penalty due by the licensee or the retailer. The giving of the information under this circumstance is not a violation of section 422.20, 422.72, or 452A.63.
