Periodically during the year, counties stop issuing tax information while they update data provided by the assessing agencies with new values and levies, reconcile their payments, issue late charges/fees, and have their tax sales.
This list contains continuously updated estimated and confirmed dates. Not all counties provide complete details, while we do get notices from some counties, with others, we aren't notified until they freeze their systems.
