Property Assessment in Montana Works Differently Than in Most States

If you go looking for a county assessor in Montana, you will not find an elected one. Most states let each county choose its own assessor. Montana gives the job of valuing all taxable property to a single state agency, the Montana Department of Revenue. The department values homes, ranches, businesses, and utilities in all 56 counties under Title 15 of the Montana Code Annotated. The county offices in our database, which are mostly county treasurers, handle the next step: billing and collecting the taxes that come from those values.

That split confuses many people. A homeowner in Billings who thinks a valuation is too high cannot simply walk into the courthouse and argue with an elected assessor. The value comes from the state. The bill comes from the county. Knowing which office controls which part will save you several wasted trips and phone calls.

Our directory holds 57 entries for Montana. The named ones include the Yellowstone County Treasurer at 217 North 27th Street in Billings and the Gallatin County Treasurer at 311 West Main Street in Bozeman. Treat these offices as your local contact for tax bills, payments, and questions about what you owe. For questions about how a property was valued, start with the Department of Revenue field office that serves your county.

Who Does What: Montana Department of Revenue, County Treasurers, and Local Governments

The Department of Revenue appraises every parcel in the state and sorts property into classes set by law. Residential and commercial land and buildings fall in Class 4. Agricultural land is Class 3, and forest land is Class 10. Each class is taxed at a different percentage of its value. The Legislature sets those percentages, not your local office, so a clerk at the courthouse cannot lower them.

Appraisal runs on a two-year cycle. Every two years the department revalues property and mails new notices to owners. Farmland and grazing land are generally valued on what the land can produce, not on what a buyer might pay for a lot with a mountain view. That rule matters across eastern and central Montana, where wheat, barley, and cattle shape the local economy.

Counties, cities, school districts, and special districts decide how much money they need and set mill levies. A mill is one-thousandth of a dollar of taxable value. The county then bills you based on the taxable value from the state and the levies from your local governments. This is why two owners of identical houses in different taxing districts can pay different amounts. The assessed value may be the same, but the levies are not.

The county treasurer mails the bills, collects payments, and issues receipts. The county clerk and recorder records deeds and related documents, which is one way the state learns that a property has changed hands. If you bought land recently and your tax bill still carries the previous owner's name, the clerk and recorder and the treasurer are the two offices to call.

Reading Your Assessment Notice and Disputing a Value in Montana

Your notice lists the property class, the market value, and the taxable value. Start by checking the facts the state has on file: acreage, square footage, year built, bathrooms, garages, and outbuildings. A wrong detail is the most common reason for an inflated value, and it is the easiest to fix. A shed that burned down or a basement that was never finished can change the number.

If the facts are right but the value still looks high, gather evidence. Recent sales of similar homes nearby, a private appraisal, and photos of damage or deferred repairs all help. Then ask for an informal review from the Department of Revenue. The request form is usually called AB-26, and the deadline is short and printed on your notice. Do not wait until the last week.

If the informal review does not settle the matter, you can appeal to your county tax appeal board. After that, the next level is the State Tax Appeal Board. Each step has its own filing deadline, so read every letter you receive carefully. Before your tax bill comes due, ask the Department of Revenue or the treasurer's office how an open dispute affects what you owe.

Metro Counties and Rural Counties: What Changes Across Montana

Montana's counties differ enormously in size and staffing. Yellowstone County includes Billings, the state's largest city, and its treasurer works from 217 North 27th Street. Gallatin County, built around Bozeman, has seen fast growth and rising home values, so notices there tend to generate more questions and appeals. In Cascade County, Great Falls has two listings, the most of any city in our database.

Two places run as consolidated city-county governments. Butte-Silver Bow combines the city of Butte with Silver Bow County, and the treasurer is at 155 West Granite Street. Anaconda-Deer Lodge County does the same, with its treasurer at 800 Main Street in Anaconda. If you live in either, one local government handles both city and county business, which can simplify who you call.

Rural counties run smaller offices. Powder River County lists its treasurer at PO Box 200 in Broadus, Blaine County at PO Box 278 in Chinook, and Chouteau County at PO Box 459 in Fort Benton. Carter County in Ekalaka (214 East Park Street) and Daniels County in Flaxville (213 Main Street) serve small populations spread across long distances. In these places a courthouse employee may handle several jobs, so call before you drive. Many ranch owners pay by mail and never visit in person.

Practical Steps for Montana Property Owners

Before you contact any office, collect what you will need. Having these items ready shortens most calls and counter visits to a few minutes:

Remember that Montana has no general sales tax, so property tax carries real weight in local budgets. Bills are due in two halves, with the first half due November 30 and the second due May 31. Mark both dates early, because late payments add interest and penalties. Phone numbers in our listings, such as 406-256-2701 for Yellowstone County or 406-582-3000 for Gallatin County, are the quickest way to confirm hours and payment methods before you go.

Property assessor offices in Montana operate under state property tax statutes that specify how properties must be valued, how often reappraisals occur, and what exemptions are available to qualifying homeowners. The state department of revenue or taxation typically provides oversight and technical guidance to county assessors to ensure consistent valuation practices statewide.

Assessor locations are available in 56 cities across Montana. They are spread across 56 counties.

Cities with the highest concentration include Great Falls, Baker, Red Lodge, where high real estate activity and complex commercial properties create greater demand for assessor services and property valuation resources.

Property owners in Montana should verify that their primary residence homestead exemption is active and confirm the annual appeal deadline with their local assessor office, as missing the deadline means waiting until the following tax year to contest a valuation.

Many county assessor offices in Montana now offer online property search tools where homeowners can view their assessed value, recent sales history, and exemption status without visiting the office. If you have questions about a recent reassessment notice, calling or emailing the assessor's office is often the fastest way to get a response before filing a formal appeal.

Using Montana County Offices Through the Tax Year

Property tax in Montana follows a steady yearly rhythm. Bills go out in the fall, the first half is due November 30, and the second half is due May 31. Between those dates, the county treasurer is the office to call for payment history, receipts, and the status of a delinquent account. Title companies and lenders often ask for this information when a property sells, so keep your paid receipts in a safe place.

In years when the Department of Revenue reappraises property, watch your mail for the assessment notice. That is the moment to check your property details and decide whether a review is worth requesting. Outside those years, you can still ask the department to correct an error, such as a wrong square footage or a building that no longer exists.

Where you live changes how you reach the office. A Powder River County owner may mail a check to a PO box in Broadus, while an owner in Deer Lodge County can visit the treasurer at 800 Main Street in Anaconda. Winter weather can close rural roads, so mail and phone calls are often the practical choice from December through March. The answers below cover the questions Montana owners ask most often.

No. Montana does not elect county assessors the way many other states do. The Montana Department of Revenue appraises all taxable property in the state and works through local field offices. County treasurers then mail the tax bills and collect payment. That is why the county offices in our Montana listings are mostly named Treasurer. If you have a question about your property's value, contact the Department of Revenue. If your question is about an amount owed or a payment, call the county treasurer.

Real property taxes are billed in two halves. The first half is due November 30, and the second half is due May 31. Counties mail bills in the fall, and the bill shows both due dates. Late payments can add interest and penalties, so do not rely on a grace period. Ask your county treasurer whether you may pay the full year at once and which payment methods the office accepts. Smaller offices, such as Fallon County at 406-778-7106, can tell you quickly over the phone.

Montana uses a two-year reappraisal cycle, and the Department of Revenue handles it. Every cycle, the department updates values to reflect the market and mails a new assessment notice to each owner. The notice shows the property class, market value, and taxable value. Read it as soon as it arrives, because the window to request a review is short. New construction, additions, and changes in land use can also change a value outside the regular cycle. If you made improvements, expect the department to take note of them.

Start with an informal review through the Department of Revenue, using the request form referenced on your assessment notice, commonly called AB-26. Include evidence such as comparable sales, a recent appraisal, or photos and estimates showing damage. If the result does not satisfy you, you can appeal to your county tax appeal board and then to the State Tax Appeal Board. Each step has a strict deadline. Ask the department or your county treasurer how an open dispute affects your bill before the due date.

Most rural owners pay by mail or phone arrangement. In Powder River County, the treasurer lists PO Box 200 in Broadus and can be reached at 406-436-2361. Fallon County's treasurer is at 10 West Fallon Avenue in Baker. Send a check with the payment stub from your bill and write your parcel number on it. Mail early enough to arrive before the due date, especially in winter. Call first to confirm whether the office accepts cards or online payments, since small courthouses vary.

Yes. Agricultural land is classified separately from homes and businesses, as Class 3 property. It is generally valued on its productive capacity, such as grazing or crop potential, rather than on what a developer might pay. Rules about acreage and actual agricultural use apply, so land that stops being farmed may be reclassified. If you operate in counties such as Sweet Grass, Teton, or Liberty, ask your Department of Revenue field office to confirm how your parcels are classified and what documents you should keep.
