Reporting

Any property you own, possess, or control at midnight on January 1 is taxable for that year.

Please report your personal property in our TransAction Portal before March 1 to avoid a penalty equal to 20% of the depreciated personal property value.

One of our employees might visit your business, agricultural operation, or field site to make sure our information is accurate and answer your questions.

Determining Property Values

  \text{Acquired Cost of Equipment} \times \text{Percent Good} = \text{Market Value} \\  \text{Market Value}\times\text{Current Tax Rate} = \text{Taxable Value} \\  \text{Taxable Value}\times\text{Mill Levies} = \text{Property Tax Owed}

Example:

For this example, we will look at calculating the personal property tax with:

  • $75,000 acquired cost
  • 75% percent good
  • 1.5% tax rate
  • 500 mill levies in the district
  \$75,000\times0.75 = \$56,250 \\  \$56,250\times0.015 = \$844 \\  \$844\times0.500 = \$422

In this example, the tax owed comes out to $422.

Detailed descriptions of the valuation methods can be found in Chapter 42.21 of the Administrative Rules of Montana.

Depreciation Schedules

Exemptions and Tax Rate Adjustment Thresholds

Exemption Threshold
The first $100,000 of the taxable market value of Class 8 property is tax exempt.
Tax Rate Adjustment Threshold
The first $6 million of property is taxed at a lower tax rate.

We assess personal property on the combined value of all personal property located in the state, by taxpayer ID.

If we can identify a company owning at least 50% of another entity, we combine the personal property tax value under the parent company’s taxpayer ID number.

See the Montana Personal Property Assessment Fact Sheet for more details.

Migratory and Special Mobile Equipment

Personal property brought into Montana at any time during the year is subject to property tax. You must report equipment brought into the state to the local county office in the county where the equipment is first used.

Montana prorates property tax based on the number of calendar months remaining when the property enters the state:

Months RemainingProrate Percentage
12100%
1191.67%
1083.33%
975%
866.67%
758.33%
650%
541.67%
433.33%
325%
216.67%
18.33%

Property Tax Refund Application

Personal property that leaves the state during the same calendar year might be eligible for a prorated property tax refund. You can get applications from your local county office.

You must submit the application to the county commissioners of the county where we assessed the property and where you paid the personal property tax.

Special Mobile Permits

Any heavy equipment that moves on, over, or across state highways requires a $5 special mobile permit. You must pay the property tax to the county treasurer when you get the permit. You must also give us proof of tax payment to avoid double assessment.

Paying Personal Property Tax

The elected county treasurer in each county bills and collects personal property tax.

The Department of Revenue does not bill or collect personal property tax.
