Assessment Calendar and Deadlines

The 2021 assessment and appeal sch22edule coincides with the implementation of iasWorld, a new integrated property tax system. 

This upgrade moves us off an aging mainframe system onto a state-of-the-art platform that allows property owners to more easily access and update property data.

Therefore, assessment mailing dates and appeal dates are subject to change. Please plan accordingly. Information will be published as it becomes available. Our phone lines remain open to the public during normal business hours and assistance is available via our website and social media channels.
