(1) An additional tax notice shall be sent, electronically or by postal mail, by April 30 to each taxpayer whose payment has not been received. Electronic transmission of the additional tax notice may be used only with the express consent of the property owner. If the electronic transmission is returned as undeliverable, a second notice must be sent. However, the original electronic transmission used with the consent of the property owner is the official notice for the purposes of this subsection. The notice shall include a description of the property and a statement that if the taxes are not paid:(a) For real property, a tax certificate may be sold; and
(b) For tangible personal property, the property may be sold.
(2) When the taxes under s. 193.481 on subsurface rights become delinquent and a tax certificate is to be sold under this chapter, a notice of the delinquency shall be sent to the owner of the fee to which these subsurface rights are attached. The additional notice may be transmitted electronically only with the express consent of the fee owner. If the electronic transmission is returned as undeliverable, a second notice must be sent. However, the original electronic transmission used with the consent of the property owner is the official notice for the purposes of this subsection. On the day of the tax sale, the fee owner shall have the right to purchase the tax certificate at the maximum rate of interest provided by law before bids are accepted for the sale of such certificate. (3) The tax collector shall send such additional notices as he or she considers proper and necessary or as may be required by reasonable rules of the department. An additional notice may be transmitted electronically only with the express consent of the property owner. If the notice of taxes is sent electronically and is returned as undeliverable, a second notice shall be sent. However, an original electronic transmission used with the consent of the property owner is the official mailing for the purpose of this section.
