About the appeals process

You have the right to appeal decisions that you disagree with, especially decisions about the taxes you owe or that you feel should be refunded. The appeals process is important and we encourage you to use it if you have an objection. Everyone should pay their share of taxes, no more and no less, and we need to be informed of our errors. You have several avenues to follow throughout the appeals process, which you can read about below or get more detail from the Tax Appeals - Reference Guide and Steps to Take.

Informal review

This is the place to start; more than 90 percent of disagreements are settled with an informal review. If you disagree with a notice from us, you’ll need to file a written objection within 30 days from the date of the first notice. For your convenience, you can download a form specifically designed for this purpose. The informal review is effective because a department supervisor reviews your case and the work of any employees involved. Read specific instructions on how to request an informal review.

Office of Dispute Resolution

If you disagree with the outcome of the informal review, the Office of Dispute Resolution is your next avenue. Nearly all of the remaining objections with the department are settled here. You need to file a written objection with the Office of Dispute Resolution within 15 days of the outcome of the informal review in step 1. There is a form specifically designed for this step as well.

The first part of this step is a scheduling conference, often held by telephone. After that, you may appear before a hearing officer who is independent of other department staff members. The decision from the Office of Dispute Resolution is considered the Department of Revenue’s final decision. If you disagree with the decision, you may make your case to the appeal bodies outside the Department of Revenue. Read specific instructions on how to file an appeal with the Office of Dispute Resolution.

State Tax Appeal BoardarrowDistrict CourtarrowMontana Supreme Court

Steps three through five involve the State Tax Appeal Board, the District Court and the Montana Supreme Court. Taxpayers usually resolve disputes well before this stage and appeal very few decisions to these bodies. The State Tax Appeal Board guarantees your right to have your dispute weighed by a panel that is fully independent of the Department of Revenue, and is simpler and less expensive than going to court. Ultimately, you can appeal to the courts. This gives you the ability to have a judicial body determine whether the decision made by the Department of Revenue is fair and appropriate.

Office of Taxpayer Assistance

Outside of the appeals process, but parallel to it, is the Office of Taxpayer Assistance.  

It is available if you have a complaint about how the department has treated you procedurally, with its service or through any inefficiencies. The office also receives complaints about any improper or abusive behavior of department employees.

The Office of Taxpayer Assistance is independent of all other Department of Revenue divisions and works to resolve taxpayer issues after the usual channels of problem solving have been exhausted or communications with the department have broken down. 

The office’s focus is ensuring you receive the protections of the Taxpayer Bill of Rights. The office doesn’t address issues of fact or law that are considered by the Office of Dispute Resolution.
