Musselshell County Tax Rates for Property Classes
Musselshell County property tax rates depend on the classification set by the Montana Department of Revenue. Montana uses nine property classes, and each class carries its own mill levy formula. The Department of Revenue applies the classification before the value reaches the county treasurer for billing.
| Property Class | Montana Classification Description | Rate Basis |
|---|---|---|
| Class 1 | Net proceeds of mines, gross proceeds coal | Production-based formula |
| Class 2 | Livestock, agricultural tools, and equipment | Per-head or per-unit |
| Class 3 | Farmstead and agricultural improvements on producing land | Taxable market value |
| Class 4 | Residential and long-term rental real property | Tiered rates since 2026 |
| Class 5 | Forest land | Forest value formula |
| Class 6 | Business and commercial personal property | Taxable market value |
| Class 7 | Non-centrally assessed public utilities | Taxable market value |
| Class 8 | Business, commercial, industrial real property | Taxable market value |
| Class 9 | Centrally assessed property and certain telecommunications | Statewide assessed value |
Residential property in Musselshell County follows the class four tiered structure. The 2026 legislative session introduced a separate mill levy bracket for parcels valued below $400,000. The Department of Revenue applies the matching tier to each residential parcel based on the appraisal value.
School district mill levies carry the largest share of every Musselshell County property tax bill. Countywide levies, city levies for Roundup, and any applicable rural fire or mosquito district levies stack on top of the base class rate.
Property Tax Assessment Process in Musselshell County
The Montana Department of Revenue reappraises all real property at 100% of market value on a two-year cycle. Musselshell County property tax assessments rotate with the state schedule, and the latest revaluation tied to the 2026 appraisal year set values for the current billing cycle. Property owners receive appraisal notices each summer with the new classification and value.
Three Steps That Shape Every Assessment
- The Department of Revenue collects verified sales of similar parcels inside Musselshell County and surrounding regions.
- Staff adjust property records for size, location, condition, and improvements to estimate each parcel’s market value.
- The Department assigns the correct property class and applies any approved exemption before sending the file to the county treasurer.
Each parcel carries a classification number that determines the mill levy. Owners can confirm the classification on the appraisal notice mailed by the Department of Revenue or through the public records resources on the Musselshell County website at https://musselshellcounty.gov.
Property Tax Calculator for Musselshell County
A Musselshell County property tax estimate starts with three values from the appraisal notice. Owners need the appraised market value, the property class, and any exemption amounts the Department of Revenue has approved. Multiplying the taxable value by the combined mill levy produces an estimated annual bill.
Four-Step Calculation Method
- Subtract any homestead reduction or long-term rental reduction from the appraised value to find the taxable value.
- Convert the total mill levy for the property’s location into a decimal by dividing by 1,000.
- Multiply the taxable value by the decimal mill rate to estimate the annual Musselshell County property tax amount.
- Divide the annual amount by two to find each half-payment if the county bills semiannually.
| Step | Example Figure | Calculation | Result |
|---|---|---|---|
| Appraised market value | $250,000 | Starting figure from DOR notice | $250,000 |
| Homestead reduction | State reduction tier | Apply tier formula | Reduced taxable base |
| Taxable value | Post-exemption figure | Used for mill levy application | See notice |
| Total mill levy | County and school combined | Divide by 1,000 | Decimal rate |
| Annual tax estimate | Taxable value × decimal rate | Final product | Estimated bill |
Owners seeking an exact figure should contact the Montana Department of Revenue through revenue.mt.gov to verify current mill levies. The Department also publishes current mill levy comparisons at revenue.mt.gov for property tax planning.
Homestead Reduction Rules for Musselshell County
The Montana homeowner property tax relief program reduces the taxable value of an owner-occupied primary residence.

Long-Term Rental Reduced Property Tax Rate
Montana introduced a reduced property tax rate for long-term rental property starting with the 2026 tax year. Musselshell County property owners who rent residential units on a lease of at least 30 days can apply for the lower class four tier. Short-term vacation rentals do not qualify.
Key Points for the Long-Term Rental Rate

The 2026 application deadline for the long-term rental rate was extended to March 20, 2026, after the Montana Department of Revenue reported technical issues with the online system. Property owners can confirm current deadlines through the Montana Department of Revenue at revenue.mt.gov.
Senior, Disabled, and Veteran Property Tax Relief Programs
Montana offers additional property tax relief programs for seniors, disabled residents, disabled veterans, and surviving spouses.

Property Tax Payment Deadlines in Musselshell County
Musselshell County property tax bills become due in two installments each year. The county treasurer mails the first bill in November for the first half and the second bill in May for the second half. Property owners can pay the full year by the first installment deadline to claim a small discount.
| Installment | Billing Month | Due Date Behavior | Late Penalty Trigger |

Delinquency Penalties and Interest on Unpaid Musselshell Property Tax
Montana adds interest and penalties to unpaid property tax bills starting the day after the missed deadline. Musselshell County property tax delinquency triggers an interest charge that accrues monthly on the unpaid balance. The county treasurer records a lien against the parcel once taxes remain unpaid past the published grace period.
Delinquency Sequence
- The county treasurer sends a delinquent notice after the second missed installment.
- Interest begins accruing at the statutory rate on the unpaid balance.
- The county files a tax lien against the parcel at the Musselshell County Clerk & Recorder office.
- The lien remains attached to the property until the full balance plus interest and fees are paid.
- Unpaid parcels may eventually face a tax lien sale to recover the debt.
Property owners can stop the delinquency process by paying the full balance plus accrued interest before the tax lien sale date. The county treasurer can provide the exact payoff amount by phone at (406) 323-2504.
How to Contest a Musselshell County Property Assessment

Value Components

Agricultural Land Tax Valuation in Musselshell County
Agricultural land in Musselshell County receives a productivity value rather than a market value assessment. The Montana Department of Revenue uses a statutory formula that considers grazing capacity, crop yield, and soil productivity to set the taxable value. This productivity valuation often produces a lower tax bill than a market value approach would.
Agricultural Class Rules
- Class two covers livestock and farm machinery.
- Class three covers the farmstead residence, barns, and related improvements.
- Class four applies to any non-agricultural residential buildings on the parcel.
- Productivity value excludes non-productive features such as homes and outbuildings.
Landowners converting farmland to non-agricultural use must notify the Department of Revenue so the parcel can be reclassified. Producers with questions about agricultural valuation can contact the Montana Department of Revenue through revenue.mt.gov.
