An assessment notice is the official document sent to property owners showing their property's assessed value for the upcoming tax year. Notices typically include the current assessed value, previous year's value for comparison, property details, and information about how to file an appeal if you disagree with the valuation. The assessment notice is distinct from your tax bill—it shows the value your taxes will be based on, not the actual taxes owing. Property owners should review their notices carefully upon receipt, as appeal deadlines are usually time-limited from the notice date.
