(Juneau) A reminder that the first installment of property taxes is due by close of business Friday at your local municipal treasurer’s office. The second installment payments are due at the county treasurer’s office by July 31. Taxpayers mailing after the deadline are subject to interest and a penalty of one and a half percent (1.5-percent) of the total amount for the first month, and that increases by 1.5-percent percent for every month the tax remains unpaid. Also, if you are late the entire tax bill is due immediately. Watertown is the only Dodge County community that allows property taxes to be paid in three installments, but all three payments must be made in the city.
