The deadline for residents to pay their 2016 property taxes is this Friday, March 31. Delinquent taxpayers must add 3 percent to their payment after March 31. For example, a typical $1,500 tax bill would jump to $1,545 on Saturday, April 1. Accounts unpaid as of May 1 are charged an additional advertising fee and are advertised in a local newspaper. If the taxes remain unpaid, the amount due will increase substantially on June 1.
