What is the amount of penalty and interest?
If taxes go delinquent, the tax collector adds a 6 percent penalty and 1 percent interest in February. Penalty continues to accrue at 1 percent per month until July 1. On July 1, the penalty is 12 percent. Interest continues to accrue at 1 percent per month until paid. For example, on July 1, unpaid taxes would have accrued a total of 18 percent penalty and interest (12 percent penalty and 6 percent interest).
To this amount, a taxing unit also may add a penalty of up to 20 percent for attorney fees.
