Procrastinators and property owners in Door and Kewaunee Counties can avoid any penalties by making sure they pay their taxes on time.  The deadline to pay the first installment of property taxes is this Friday.  Tax payments can be dropped off at the respective treasurer's office at the downtown government center from 8 am until 4:30 pm in Sturgeon Bay and at the Kewaunee County Administration building in Kewaunee. Payments can also be mailed as long as it is postmarked January 31.  Real estate owners who are delinquent can be assessed a 10 percent late payment fee along with additional administrative fees.
