The Montana tax appeal process gives residents and businesses a structured way to challenge state tax decisions they believe are incorrect. When the Department of Revenue issues an assessment or decision, taxpayers have the right to request a review through a clear and organized process designed to ensure fairness and transparency. This system enables individuals and organizations to resolve disputes related to taxation, property assessments, and other matters without resorting to immediate court action.

A Montana tax appeal typically begins at the administrative level, where the department reviews the case before it can advance to higher levels of appeal. Each step gives both parties—the taxpayer and the department—an opportunity to present evidence, clarify information, and reach a fair resolution. The process also ensures that taxpayers can continue normal operations, whether personal or business-related, while their appeal is under consideration.

Understanding how to file, what forms are required, and which board or agency handles specific types of appeals is essential. This guide explains every stage in detail, from the initial review with the Department of Revenue to the Montana Tax Appeal Board, district court, and, when necessary, the supreme court. By following the correct steps and adhering to the timelines, taxpayers can effectively navigate the process and protect their rights under Montana law.

Understanding the Montana Tax Appeal System

Residents and businesses in Montana have multiple options to settle disagreements about taxes, assessments, and property values through the tax appeal system. Every taxpayer is guaranteed a fair review at several administrative levels prior to any judicial trial being considered, thanks to its design. Each level serves a specific purpose, helping parties address errors or disagreements efficiently and lawfully.

Key Agencies Involved in the Montana Tax Appeal Process

  1. Montana Department of Revenue (DOR)
    The Montana Department of Revenue is the first point of contact for any tax appeal. It reviews tax assessments, determines property values, and handles all initial appeals. The department also issues notices, manages filings, and processes applications submitted by taxpayers seeking review or adjustment of their tax returns.

  2. Office of Dispute Resolution (ODR)
    Within the department, the Office of Dispute Resolution functions as a separate division. It looks at what happens when taxpayers disagree with decisions made during the informal review. Administrative Law Judges are responsible for conducting hearings and ensuring that both parties have the opportunity to present their evidence and arguments.

  3. Montana Tax Appeal Board (MTAB)
    The Montana Tax Appeal Board is a fair forum for reviewing decisions made by the department and the ODR. This independent board, based in Helena, handles complex cases and appeals that may involve businesses, property owners, or multiple types of taxes.

  4. County Tax Appeal Boards (CTABs)
    Each county in Montana has its own tax appeal board that primarily manages property-related disputes. These local boards enable residents to contest property assessments without having to travel to Helena or file directly with MTAB.

  5. District Court and Supreme Court
    Taxpayers who disagree with MTAB’s final decision may file an appeal with the district court. In rare cases involving significant legal issues, further appeal may proceed to the Supreme Court. Both levels focus on questions of law rather than re-evaluating the facts of the case.

This arrangement ensures that taxpayers have a range of options for contesting tax rulings and obtaining a fair resolution. Residents and businesses can effectively defend their rights under Montana law and navigate the process with confidence if they know which agency to contact and how each level of the system operates.

Step 1 – Request an Informal Review

Requesting an informal review from the Department of Revenue is the first step in the Montana tax appeal procedure. This stage allows individuals and businesses to communicate directly with the department about issues related to taxes, assessments, or property values, before proceeding to a higher level of appeal. It is an essential opportunity to resolve problems quickly and often without the need for formal hearings.

Filing requirements:

  • Taxpayers must submit a written objection to the department within the time frame outlined in the notice. The taxpayer's name, address, Montana Account Number, and either their Social Security number or Federal Employer Identification Number must be included in the objection.

  • The type of tax involved—property, business, or income tax—as well as the particular assessment or decision under challenge, should be made clear in the filing.

  • Taxpayers should provide a written explanation of their objection along with any documentation that supports their position, such as receipts, appraisals, or relevant correspondence.

Submission methods:

  • Taxpayers can file the request by email at DORObjections@mt.gov or by mailing it to the Montana Department of Revenue, DOR Objections, P.O. Box 7149, Helena, MT 59604-7149.

  • It is essential to retain a copy of all documents sent and record the date of submission, in case additional information is required later.

Common errors to avoid:

  • Failing to file the objection by the specified deadline may result in losing the right to appeal.

  • Submitting incomplete forms or missing required details can delay the process or result in the department dismissing the appeal.

  • Waiting too long to provide supporting information can weaken the taxpayer’s position and extend the review period.

Once the Department of Revenue receives the request, it reviews the case, considers all submitted documentation, and may contact the taxpayer for clarification. In many cases, the informal review process resolves disputes without further action, saving both time and costs for all parties involved.

Step 2 – Appeal to the Office of Dispute Resolution (ODR).

The next step is to file an appeal with the Office of Dispute Resolution if the taxpayer is unhappy with the outcome of the informal review. The ODR is an impartial part of the department that ensures hearings are fair by utilizing Administrative Law Judges who are not affiliated with the staff that made the initial decision.

How the ODR process works:

  1. The taxpayer files a notice of referral to the ODR using the appropriate form, typically Form APLS102F or Form CB-2, within the required timeframe.

  2. The case is assigned to an Administrative Law Judge who reviews all submitted evidence and determines if a hearing or mediation is necessary.

  3. Hearings are often conducted remotely through video or telephone conferencing to make the process accessible to all Montana residents.

  4. Both parties may submit exhibits, present witnesses, and provide written statements supporting their positions.

  5. The judge issues a written decision that explains the findings of fact and conclusions of law based on the evidence presented.

Mediation option:
At this point, the taxpayers and the department may agree to mediation. Under the direction of an impartial mediator, this voluntary process allows both parties to discuss potential settlements. Mediation often reduces the time and expense of formal proceedings.

The ODR ensures that both parties have a fair opportunity to review the case. It provides taxpayers with a neutral forum to question the department's findings. The taxpayer can proceed to the next level of appeal if they remain dissatisfied with the decision from this office.

Step 3 – Appeal to the Montana Tax Appeal Board (MTAB).

The Montana Tax Appeal Board is the final administrative level where taxpayers can challenge Department of Revenue decisions before seeking judicial review. The board is independent and located in Helena, providing hearings for property, income, and business tax disputes.

Filing requirements:

  • Taxpayers must file their appeal within 30 days of receiving the final decision from the Office of Dispute Resolution.

  • The appeal should be submitted using Form 801-MTAB and include all supporting documentation, correspondence, and prior decisions related to the case.

  • MTAB requires clear identification of the tax type, the year involved, and the specific issues being appealed.

Hearing process:

  • Depending on the type of case and the location of the parties, hearings can be conducted in person, by video, or by phone.

  • Each side may present evidence, call witnesses, and cross-examine the opposing party’s witnesses.

  • The board reviews all facts, evaluates testimony, and issues a written decision explaining its ruling.

  • In some cases, MTAB may modify or reverse the department’s decision if it finds sufficient evidence to support the taxpayer’s claim.

Outcome and next steps:
Once MTAB issues a decision, it becomes the final administrative determination. Taxpayers have 60 days to appeal to the district court if they are dissatisfied with the outcome of their case. With this step, the process transitions from an administrative review to a judicial proceeding, where the case focuses on legal issues rather than reexamining facts.

The Montana Tax Appeal Board serves as an essential safety net, ensuring the state's tax system is fair and accountable. Taxpayers can effectively present their cases and seek the appropriate remedy under Montana law if they comprehend the system and are cognizant of the deadlines.

Step 4 – Judicial Review in Montana District Court.

When a taxpayer disagrees with the final decision of the Montana Tax Appeal Board, the next available option is to seek judicial review in the district court. This step moves the case into the judicial system, where a judge reviews the legal basis of the decision rather than re-evaluating the facts already presented.

Judicial process overview:

  • The taxpayer must file a petition for judicial review within 60 days after the Montana Tax Appeal Board issues its final decision.

  • The district court reviews the administrative record from the previous proceedings, including all evidence and written decisions.

  • Hearings may be scheduled for oral arguments, but no new evidence is typically accepted unless procedural or constitutional issues arise.

  • The court focuses on whether the previous rulings complied with Montana law and followed proper administrative procedures.

Further appeal:
If the taxpayer or the department disagrees with the district court’s decision, they may file an additional appeal with the Montana Supreme Court. The Supreme Court reviews only legal questions and ensures consistency in the interpretation of state tax laws.

Judicial review offers taxpayers a final opportunity to challenge decisions through the court system. It ensures that every taxpayer has full access to the legal process and that decisions are made in accordance with the law and the facts established during administrative hearings.

Deadlines and Filing Requirements for Montana Tax Appeals

Meeting all deadlines is critical in the Montana tax appeal process. Missing a deadline may forfeit a taxpayer’s right to appeal, regardless of the case’s merit. Each appeal level has a specific filing period, which varies depending on the type of tax and the issuing agency.

Informal review deadlines:

  • For centrally assessed property, the taxpayer must file the objection within 20 days of the notice date.

  • For other tax types, such as income or corporate taxes, the deadline is generally 45 days from the date the notice was issued.

  • The department may allow an extension to provide additional information, but the initial filing must be made before the deadline.

Office of Dispute Resolution deadlines:

  • Centrally assessed property appeals must be filed within 15 days of the informal review determination.

  • All other tax types must be filed within 45 days after receiving the department’s decision.

Montana Tax Appeal Board deadlines:

  • Appeals to the Montana Tax Appeal Board must be filed within 30 days of the Office of Dispute Resolution’s final decision.

Judicial review deadlines:

  • A taxpayer seeking review in the district court must file within 60 days of receiving the board’s decision.

These timeframes ensure the process moves efficiently and allows both parties to prepare adequately. Taxpayers should always record submission dates and maintain copies of all correspondence to verify compliance with these filing requirements.

Property Tax Appeals: Special Procedures and Forms

Property tax appeals in Montana follow specific procedures that differ from other types of taxation disputes. These cases often begin at the county level, allowing residents to contest property assessments locally before proceeding to the state board or courts.

County Tax Appeal Board process:

  • Taxpayers must file an appeal within 30 days of receiving their classification and appraisal notice.

  • The filing requires the use of the proper form, such as Form 401-CTAB, and submission to the county clerk and recorder’s office.

  • Hearings are conducted locally, where taxpayers can present evidence, such as comparable property sales or independent appraisals, to support their claims.

  • The county board evaluates the evidence and issues a written decision outlining the result.

Appeals to the Montana Tax Appeal Board:

  • If the taxpayer disagrees with the county board’s decision, an appeal may be filed with the Montana Tax Appeal Board within 30 days of the date of the decision.

  • Property cases reaching MTAB are reviewed in detail, often involving professional appraisals and market value analyses.

Paying taxes under protest:

  • Taxpayers may pay disputed property taxes under protest to maintain their appeal rights.

  • A written protest must accompany payment to the county treasurer, specifying the reason for the protest and the amount contested.

  • This step prevents delinquency penalties and ensures eligibility for refunds if the appeal is successful.

Property tax appeals provide a clear framework for challenging valuations while protecting taxpayer rights. By following the correct forms, deadlines, and submission requirements, residents can effectively dispute assessments and ensure fair treatment under Montana law.

Alternative Dispute Resolution and Mediation Options

Montana encourages taxpayers and the Department of Revenue to resolve disputes through alternative methods before proceeding to formal hearings. The mediation process allows both parties to discuss their differences in a less formal setting and work toward a mutually acceptable resolution.

Mediation process:

  • Either party may request mediation once an appeal has been submitted to the Office of Dispute Resolution or the Montana Tax Appeal Board.

  • A neutral mediator helps guide the discussion, ensuring each party has an opportunity to explain its position and propose solutions.

  • Both the taxpayer and the department must agree to mediation for it to proceed, and any resulting agreement must be put in writing.

Benefits of mediation:

  • It reduces costs and time compared to full hearings or court trials.

  • It gives the parties more control over the outcome rather than leaving the decision entirely to a judge or board.

  • It helps maintain a cooperative relationship between taxpayers and the department, especially in cases involving ongoing property or business taxation issues.

Alternative dispute resolution is a practical tool that supports fair outcomes without requiring lengthy proceedings. By choosing mediation, taxpayers can often achieve faster resolutions while preserving their right to appeal.

How Montana Tax Appeals Differ from IRS Appeals?

While both systems provide avenues for taxpayers to challenge decisions, the Montana tax appeal process differs significantly from the procedures used by the Internal Revenue Service. These differences affect the structure, timelines, and representation rules for each system.

Key structural differences:

  • The Montana system comprises several levels of review, including the Department of Revenue, the Office of Dispute Resolution, the Montana Tax Appeal Board, and the district court.

  • The Internal Revenue Service process involves fewer steps, generally beginning with the Independent Office of Appeals and progressing to the federal tax court if necessary.

  • Montana’s boards and offices serve as administrative bodies created to resolve state-level disputes rather than federal matters.

Procedural distinctions:

  • Montana allows taxpayers to represent themselves or appoint another individual without requiring an attorney, whereas IRS proceedings often involve the use of legal representation.

  • The state uses unique forms and deadlines, such as the APLS and CAB series, which differ from those used by the federal government.

  • Montana appeal deadlines typically range from 15 to 60 days, depending on the case type, while federal timelines may be longer.

Understanding these distinctions helps taxpayers manage both state and federal obligations effectively. Those involved in cases that affect both Montana and IRS assessments should handle each process separately, ensuring all requirements are met under the applicable jurisdiction.

Preparing for a Successful Appeal

Proper preparation greatly increases the likelihood of success in a Montana tax appeal. Whether the case involves property, income, or business taxation, presenting clear evidence and following procedures carefully are essential steps.

Preparation tips:

  • Taxpayers should collect and organize all documents related to their case, including notices, correspondence, receipts, and assessment records.

  • It is helpful to prepare a written explanation that summarizes the reasons for the appeal and the relief sought.

  • Reviewing the Department of Revenue’s valuation or audit methods can help identify specific points of disagreement.

  • Witnesses or experts, such as professional appraisers or accountants, can strengthen the case by providing credible testimony.

  • All materials should be labeled, numbered, and presented clearly during hearings or reviews.

When to seek professional assistance:
Although an attorney is not required for most Montana appeals, consulting a tax professional or a legal advisor may be beneficial for complex or high-value cases. Experienced advisors can help clarify laws, meet deadlines, and prepare thorough documentation.

Adequate preparation ensures that both residents and businesses present strong, well-supported appeals. By staying organized and informed, taxpayers can navigate the process efficiently and achieve fair consideration from the reviewing authorities.
