With the exception of registered motor vehicles, property taxes are due September 1st of each year and are considered delinquent if not paid by January 5th. Interest will be added January 6th at the rate of 2% and an additional 3/4% each month thereafter until the amount is paid in full. A 2% discount is given if payment is received prior to September 1st. 

The due date for taxes on registered motor vehicles is determined by the plate expiration date. A tax notice is usually prepared and mailed approximately 3 months after the tag is renewed or a new tag is purchased. Interest will be added on the 1st day of the second month following the date of the notice at the rate of 5% the first month and 3/4% each month thereafter until paid in full.
