This website provides you access to the Board’s case management system and allows you to file a petition for appeal to the BAA, payment of the appropriate filing fee, if any, and the subsequent filing of any case related documents. This case management system is the system of record for all of the BAA’s cases and should be used to file any type of BAA appeal.  Cases and subsequent documents filed within the system are served on the opposing party electronically.  In addition, all Board orders and decisions are issued through this system.  It is important that you monitor the email provided when you set up your account access as it is your responsibility to meet any deadlines for responding to motions filed by the opposing party or orders issued by the BAA.  

Petitioners are solely responsible for the accurate and timely filing of their appeals with the BAA. Once you file a petition within this system, you will receive an automated receipt by email showing that your appeal was received. If you do not receive this automated receipt, please call our office prior to the deadline for filing the appeal in order to ensure that we received your appeal. 

You are strongly encouraged to read the Rules of the Board of Assessment Appeals and access the User Guides available here, prior to using the system/filing a petition.
