The Withdrawal Form for Informal Review or Appeal (Form AB-63) is an official document issued by the Montana Department of Revenue for property owners who wish to voluntarily cancel an existing request for a property tax review. Property owners initially use the AB-26 form to dispute their property’s classification or appraisal value, triggering an informal review process. However, circumstances often change—a taxpayer might reach a satisfactory verbal agreement with an appraiser, discover they misinterpreted their assessment notice, or simply decide that pursuing the appeal is no longer necessary or beneficial. In these cases, Form AB-63 serves as the formal legal mechanism to stop the review process. By signing and submitting this document, the property owner effectively tells the Department of Revenue, “I no longer want to challenge my property value,” and officially waives their right to continue that specific appeal for the current tax cycle. It is a critical administrative step to close the file on a dispute and finalize the property’s assessed value as originally determined or subsequently agreed upon.
How To File Form AB-63
Filing this form is a straightforward process, but it requires sending the document to the correct location to ensure your withdrawal is processed immediately.
- Where to Submit: You must submit the completed copy of Form AB-63 directly to the local Department of Revenue office located in the county where your property is physically situated. Do not send it to the main headquarters in Helena unless your local office instructs you otherwise.
- Method: You can typically mail it or drop it off in person. It is advisable to keep a copy for your own records before handing it over.
- Timeline: Submit this form as soon as you have made the final decision to withdraw your appeal to prevent further administrative actions or scheduled hearings regarding your property.
