Request an Informal Conference

The informal conference process is available to any taxpayer that has received a proposed assessment of tax. It is free, and a taxpayer may participate in a conference without representation. The primary role of Department of Revenue hearing officers is to make an independent determination of whether a proposed assessment is correct. A hearing officer can adjust an assessment based on a review of state law or any additional information received.

A taxpayer must make a conference request in writing within 30 days from the date of the Notice of Proposed Assessment.  Please complete and submit a Request for Informal Conference to Review Proposed Assessment or Refund Denial form, along with a copy of your Notice of Proposed Assessment.

If a conference request is made within the 30-day time period, the Department of Revenue will contact the taxpayer within 10 days of the request to arrange a time and date for the conference to take place.
