Policy Basics: Property Taxes in Montana

The Montana property tax system supports local public services, including schools, roads, and other infrastructure. Residential property owners pay almost half of all property taxes. Every two years, the state undergoes a reappraisal process to update the property values for purposes of property taxes.

Property Taxes Educate Children and Protect Families

State and local property taxes collected in Montana make up approximately 40 percent of our total state and local tax revenue, for a total of $1.8 billion in FY19.[1] The vast majority of these funds are directed toward local governments and schools to invest in public services we all rely on. Eighty-three percent of property tax revenue is invested in local governments, including supporting local schools, services like fire protection, and infrastructure, such as roads and bridges (Figure 1).[2] The state of Montana receives about 17 percent of property taxes through statewide mills – to ensure equitable support of local schools, universities, and technical colleges.[3] 

Families Living on Low Incomes Pay Greatest Share of Income in Property Taxes  

Montana homeowners pay a large portion of total property taxes, representing about 49 percent of all property tax revenue.[4] While property taxes are greater for homes of higher value, the property tax system is still considered regressive, meaning that, on average, households with higher incomes pay a smaller share of their income in property taxes than households living on lower incomes. In Montana, property taxes paid by the wealthiest 1percent of taxpayers represents 1.6 percent of their overall income, compared to 5.3 percent of income for the Montanans living on the lowest incomes (Figure 2).[5]

Property taxes tend to be regressive because they do not take into account a homeowner’s income or ability to pay and because housing costs tend to be larger in proportion to the income of households living on lesser means than households with more wealth.[6] For example, a family making $50,000 a year may own a home costing $150,000, or three times their wages, while a family making $1 million per year may own a home costing $500,000, or half their pay. Therefore, the property taxes paid by the household living on low income will represent a greater proportion of their family income than the property taxes paid by a household with high income.

It is important to remember that property taxes are not limited to property owners. Renters pay a portion of the property taxes paid on rental properties because the taxes are “passed through” by the landlords when setting the rent amount.[7]Both State and Local Governments Play a Role in Assessing Property Taxes

Determining what the property taxes will be on a piece of property is complicated and requires a series of steps. The Montana Department of Revenue is responsible for appraising - or valuing - property in the state to determine the market value.[8] Each taxing jurisdiction – county, city, or school district – uses these values to calculate property taxes.

The Montana Legislature created 15 different classes of property, including residential and commercial property, agricultural land, business equipment, and centrally assessed property.[9] Centrally assessed property is property owned by a company operating as a single entity and connected across county or state borders. This includes things like railroads, telecommunication lines, power lines, natural gas or oil transmission lines, and airlines. Each property within a class is valued in the same manner. For residential property, the market value is the value for which the property would sell between a willing buyer and willing seller.[10] The department uses the sales price of similar properties in the area to determine a value for properties that have not been sold.[11]

The Montana Legislature then assigns a tax rate to each class of property and multiplies that tax rate by the property’s market value to determine the taxable value. The tax rate in 2018 was 1.35 percent for residential property and 1.89 percent for commercial property.[12] Local taxing jurisdictions – cities and counties – apply the mill levies to the property’s taxable value to determine taxes owed. County governments are responsible for collecting property taxes and distributing the appropriate portion of those taxes to the state, cities, school districts, and other taxing jurisdictions.[13] 

Reappraisal Process Critical to Accurately Valuing Property

The Montana Constitution and state law require the Montana Department of Revenue to reappraise all property periodically and value similar property across the state in the same manner.[14] The reappraisal process is an important component in ensuring local governments, schools, and the state are accurately reflecting property values for property tax purposes. Taxing jurisdictions in the state set their budgets and mills based on these updated values. Tax year 2015 began the first year of a two-year appraisal cycle for residential, commercial, industrial, and agricultural property.[15] Forest land remains on a six-year appraisal cycle. The Legislature maintained the tax rates for all classes in the most recent legislative sessions. The impact on individual homeowners depends on market values in their region or county and varies from home to home.

Homeowners Pay the Greatest Share of Total Property Taxes

Property taxes paid by residential homeowners comprise almost half of all property taxes (Figure 4).[16] In fact, Montana homeowners have seen an increase in the share of property taxes they pay compared to other classes of property (Figure 5).[17]

Residential property owners pay a greater share of property taxes, in part because the Legislature has cut the tax rates on other property classes. For example, over the past several decades, the effective tax rate on business equipment has fallen by more than 50 percent.[18] This often results in a shift of tax liability to other property taxpayers over time.[19] The Legislature caps the amount local governments can raise from property taxes.[20] When the Legislature cuts the tax rates for some property classes, the total taxable value in the entire local jurisdiction decreases. When the taxable value goes down, so does the amount of revenue for that jurisdiction. To maintain revenue levels, the local jurisdiction would have to raise its mill levies on all property owners.[21] The increased mill levies are then applied to the remaining property in the jurisdiction, most significantly to residential property. As a result, local revenue remains constant, but the obligation to support local government functions shifts to homeowners and other property owners.While Montana’s local governments and schools rely heavily on property tax for needed revenue, Montana’s effective tax rate for property tax is lower than the national average. Montana generates a large portion of its total taxes from property tax (40 percent), compared to the national average of 31 percent.[22] This difference, however, is due to the fact that Montana does not have a sales tax like most other states. Nationwide, Montana ranks 33rd for its effective residential property tax rate of 0.73 percent. The national median is 1.05 percent.[23]

Property Taxes in Indian Country

The taxation of property in Indian Country is often misconstrued as a “loss” of tax revenue. First and foremost, it should be clarified that the tax base was never “lost” as it never existed in the first place. All reservations consist of lands that tribal nations either reserved from their land cessions to the U.S. or lands set aside for their exclusive use via statutes and executive orders. Land owned collectively by the tribal nation, as well as land allotted to individual tribal citizens in accordance with the General Allotment Act of 1887, is called trust land and is held in trust for tribal nations by the federal government. Similar to all other federal property, such as national parks and forestlands, trust land cannot be taxed and is therefore not subject to state or local property taxes.[24]

As a result of the forced allotment of many reservations, there are now parcels of fee land that are privately owned and subject to state and local property taxation. This includes fee land owned by tribal citizens, even when their property is located on their reservation.[25]

To help offset the loss of property taxes that support local public schools, districts located on reservations and other federal lands can apply for federal Impact Aid, also known as Title VII funds.[26] Through Impact Aid, 78 public schools in Montana received nearly $67 million in federal aid in 2019. Sixty-seven of these school districts included reservation land.[27]

The State Provides Assistance for Property Taxpayers Living on Low Incomes 

The Montana Legislature has put in place four distinct programs to reduce property tax liability for some homeowners. The largest of these programs, the Elderly Homeowners/Renter Credit, provides taxpayers age 62 or older with household incomes less than $45,000 an income tax credit to help offset property taxes. The refundable credit is capped at $1,000 and phases out at incomes between $35,000 and $45,000.[28] In 2017, 13,567 Montana seniors with income tax liability received the Elderly Homeowner/Renter Credit.[29]

The state also provides two property tax programs that directly reduce property taxes for certain households. The first, the Property Tax Assistance Program (PTAP), reduces residential property taxes for households with lower incomes. The taxpayer must live in their home for at least seven months out of the year and have incomes below $21,607 for one eligible owner (or below $28,810 for a property with two eligible owners).[30] In 2018, more than 23,000 property taxpayers received assistance through PTAP, nearly a threefold increase since 2006.[31]

The state also provides the Disabled American Veterans (DAV) program, which provides property tax assistance for disabled veterans. The property must be the taxpayer’s primary residence, and a taxpayer qualifies if they are a veteran honorably discharged and paid at the 100 percent disabled rate for a service-connected disability.[32] A spouse of a veteran who was killed while on active duty or who died from a service-connected disability may also be eligible for the DAV program. In 2018, more than 2,500 veterans or family members received assistance through the Disabled American Veterans program.[33]

In 2017, the Legislature created a new property tax assistance program starting in 2018 for long-time property owners where the value of their land is disproportionately higher than the value of their home.[34] The program caps the land value of their primary residence parcel to 150 percent of the improvement value, subject to a minimum per acre value consistent with the statewide average value.[35] To qualify, the owner must live in the property for at least seven months of the year and have owned (or family owned) the property for at least 30 years.

State Budget Cuts Put Strain on Property Assessment Process

The 2017 legislative session resulted in deep cuts to nearly all state agencies, including the Montana Department of Revenue. As a result of lower revenue levels, the governor and Legislature cut approximately $6 million in general fund appropriations from the Department.[36] Within the Department, the Property Assessment Division (PAD) faced the most severe cuts, with the closure of half of all county property assessment offices and a loss in the number of staff positions.[37] Fewer office locations result in people living in rural communities with less access to those who determine property values and set property taxes, which are a significant portion of a households state and local taxes.


Montana’s property tax system provides important funding for education through our local schools, infrastructure like our roads and bridges, and other local services like fire protection. Elected officials, like our state legislators, have a very important role in deciding how our property tax system works. The Department of Revenue’s role to reappraise property in the state ensures a fair system of valuing property for purposes of taxation.

Unfortunately, Montanans living on lower incomes pay a larger share of property tax than Montanans with high salaries. There are further options for improving the fairness of our state property tax system, in addition to those already in existence, such as our property tax assistance programs and a fair, statewide reappraisal schedule. Further connecting income to property taxes would assure that Montanans with lower incomes are not priced out of their homes due to increases to property taxes. Also, continuing to broaden the property tax base rather than passing further exemptions can stop the increasing share of property taxes paid by residential homeowners.
