Certified Property Values and Mill Levies

The “Certified Values” are total taxable property values determined by the Department of Revenue for each tax jurisdiction.

The department provides these values to the tax jurisdictions every year on the first Monday in August.

2020 Certified Values will be available on August 3, 2020.

The full details of the report, including the certified values of every tax jurisdiction and the statewide totals can be can be found at Property.MT.gov.

Local governments establish their budgets and set their mill levies for property tax calculation and collections based on the certified taxable value provided to each taxing jurisdiction.

Calculating Levies and Property Tax

To calculate the number of mills in each jurisdiction and property tax due, follow the steps below.

This procedure is outlined in 15-10-420, MCA.

Step 1

Calculate Adjusted Property Tax Revenue (APTR)

The current year’s adjusted property tax revenue is equal to the jurisdiction’s previous year’s property tax revenue increased by one-half of the average rate of inflation over the previous three years:

\text{APTR} = \text{Previous Year's APTR} \times \left(1 + \left(\frac{\text{3 Years Inflation}}{2}\right)\right)

Step 2

Calculate Maximum Mills

Next find the jurisdiction’s maximum mills.

This is 1,000 times the jurisdiction’s Adjusted Property Tax Revenue (APTR) divided by its Certified Taxable Value minus its Newly Taxable Value (Rounded down to the third decimal):

\text{Maximum Mills} = 1,000 \times \left(\frac{\text{APTR}}{\text{Certified Taxable Value} - \text{Newly Taxable Value}}\right)

Step 3

Calculate Millage Rates

Find the Millage Rate. This is the total number of mills from all jurisdictions for your property divided by 1,000.

\text{Millage Rate} = \frac{\text{Total Mills}}{1,000}

Step 4

Estimate Property Tax

Finally, property owners multiply the Taxable Value by the Millage Rate to find their Property Tax.

\text{Property Tax} = \text{Taxable Value} \times \text{Millage Rate}

This is an estimate of general property taxes. Local governments may also assess special fees and assessments. Property owners should contact their County Treasurer for more information on special assessments or fees.

Example Levies and Property Tax

For this example, we will look at a property with a $2,793 Taxable Value, in one tax jurisdiction with:

  • Previous Year’s Property Tax Revenue: $1,000,000
  • Three Year Inflation: 2%
  • Current Year Certified Taxable Value: $2,000,000
  • Newly Taxable Value: $100,000

We will also assume a second tax jurisdiction with 304 mills.

Step 1

Calculate Adjusted Property Tax Revenue (APTR)

\text{APTR} = \$1,000,000 \times \left(1 + \left(\frac{0.02}{2}\right)\right)
\text{APTR} = \$1,000,000 \times 1.01
\text{APTR} = \$1,010,000

Adjusted Property Tax Revenue: $1,010,000

Step 2

Calculate Maximum Mills

\text{Maximum Mills} = 1,000 \times \left(\frac{\$1,010,000}{ (\$2,000,000 - \$100,000)}\right)
\text{Maximum Mills} = 1,000 \times \left(\frac{\$1,010,000}{\$1,900,000}\right)
\text{Maximum Mills} = 1,000 \times (0.531)
\text{Maximum Mills} = 531

Maximum Mills: 531

Step 3

Calculate Millage Rates

Find the Millage Rate. This is the total number of mills from all jurisdictions for the property divided by 1,000.

\text{Millage Rate} = \frac{531 + 304}{1,000}
\text{Millage Rate} = \frac{835}{1,000}
\text{Millage Rate} = 0.835

Millage Rate: 0.835

Step 4

Estimate Property Tax

\text{Property Tax} = \$2,793 \times 0.835
\text{Property Tax} = \$2,332.16

Property Tax: $2,333

Tax Increment Financing (TIF)

Tax Increment Financing (TIF) is a way for certain districts to use property tax revenue to fund new development. It works by separating taxable value into base and increment values, so that revenue from the base value continues to go to the regular taxing jurisdiction, but as taxes increase over the years, that growth—the increment—go to the TIF to pay for development activities within the TIF district.

The development of TIF districts is authorized by 7-15-4282, MCA.

Tax Increment Financing may be used to pay for a variety of development activities within the TIF district including:

  • land acquisition;
  • demolition and removal of structures;
  • relocation of occupants;
  • infrastructure costs;
  • construction of publicly owned buildings and improvements;
  • administration of urban renewal activities; and
  • payment of bonds issued to fund such costs.

(See 7-15-4288, MCA for more details)

Upon expiration of the TIF, the increment is released back to the local governments and the state. State and local governments use the released increment as newly taxable property for 15-10-420, MCA purposes. Schools treat the released increment as an increase in their tax base and adjust their mill levies accordingly.

TIF districts expire on the the 15th year following its adoption, or upon the full payment of all bonds for which tax increment revenue have been pledged, whichever is later. TIFs may extend their expiration date by securing bonds that pledge post-15th-anniversary-increment as repayment. No term extensions are allowed for bonds secured after the 15th anniversary of tax increment provisions. For example, if a TIF was authorized January 1, 2000, it has until January 1, 2015 (its 15th anniversary) to pass bonds secured by future increment to extend the expiration date. Additional bonds may be passed after the 15th anniversary but these would not extend the life of a TIF.

Please Note:

TIF districts collect the incremental tax revenue from all the local and state mills except the statewide six-mill levy that is used to fund the university system.

Due Dates for Local Governments

August 1
Local governments must notify the department of the name of the proposed TIF district, its contact person, its desired base year, and a preliminary legal description. This must be accompanied by a map illustrating the proposed boundaries of the district if the local government wants the department to provide them with a list of the affected real property, separately assessed improvements, and personal and centrally assessed properties within the district.

Recommended TIF District Setup in a County System

A Tax Increment Finance district is always set up as one or more distinct levy districts.

The department recommends setting up TIF districts through a process similar to applying a special district flat fee. Calculate the base and increment percentage for the district as a whole and then apply the base or increment percentage globally to all of the records in the affected TIF levy districts.

Administering the TIF in this way would avoid tax bills with negative increments. It would also ensure that all properties within the TIF district contribute proportionally to the TIF fund.

The following tables demonstrate this concept.

Base Taxable Value is the taxable value from the year designated as the base year in the TIF district documentation.

 Current Taxable ValueBase Taxable ValueIncrement Taxable Value

Increment Percent to TIF
\text{Increment \% to TIF}=\text{Total Increment}\div\text{Total Current Taxable Value}
Remaining Percent to Base
\text{Remaining \% to Base}=\text{Total Base Value}\div\text{Total Current Taxable Value}
The Increment Percent is applied to each TIF Levy District’s Current Taxable Value
\text{TIF Levy District 1 Increment} = \text{Increment \%} \times \text{TIF Levy District 1 Current Taxable Value}
\text{TIF Levy District 2 Increment} = \text{Increment \%} \times \text{TIF Levy District 2 Current Taxable Value}
\text{Total TIF Increment} = \text{TIF Levy District 1} + \text{TIF Levy District 2}
The Total TIF Increment should also equal \text{TIF Levy 1} + \text{TIF Levy 2} from the table above.

\text{TIF Levy District 2 Increment} = 1,283,903
Total TIF Increment
\text{Total TIF Increment} = \text{TIF Levy District 1} + \text{TIF Levy District 2}
\text{Total TIF Increment} = 2,951,508 + 1,283,903
\text{Total TIF Increment} = 4,135,411

General setup process:

  • Enter the Base Percent into a custom field.
  • Apply the Base Percent globally to the records in the affected TIF levy districts.
  • At the property record level, calculate:
    Taxable Value × Base Percent
    The taxes levied against the result would receive normal distribution to all affected taxing jurisdictions.
    Remaining Taxable Value
    The taxes levied against the result would be distributed to the TIF district fund except for the six university mills.

TIF Increment Example

Base taxable value is the total taxable value in the TIF district in the year prior to the existence of the district. Incremental taxable value is the taxable value that exceeds the base taxable value for the district in any year. For example, if in the year a TIF is created, the base year and current year taxable value are equal to $1 million, there would be no incremental taxable value and no TIF revenue.

TIF Taxable ValueBase Year
TIF Revenue$0
Current Year Taxable Value$1,000,000
Base Taxable Value-$1,000,000
Increment Taxable Value$0
Millage Rate×0.500

If in the second year of existence of a TIF district, its taxable value grew by $100,000, then the incremental value in that year would be $100,000. If the total millage rate in the TIF was 0.500, the taxes generated from the increment (TIF revenue) would be $50,000.

TIF Taxable ValueBase YearYear 2
TIF Revenue$0$50,000
Current Year Taxable Value$1,000,000 $1,100,000
Base Taxable Value($1,000,000)($1,000,000)
Increment Taxable Value$0$100,000
Millage Rate×0.500×0.500

If in the third year of the TIF district, the taxable value shrinks to $800,000, due to property devaluation, demolition or removal of structures, or the like, then the incremental value would be negative ($200,000), meaning there would be no incremental value for the third year. When a TIF district’s incremental value is less than zero, no revenue is provided to the district.

TIF Taxable ValueBase YearYear 2Year 3
TIF Revenue$0$50,000 $0
Current Year Taxable Value$1,000,000 $1,100,000 $800,000
Base Taxable Value($1,000,000)($1,000,000)($1,000,000)
Increment Taxable Value$0$100,000 ($200,000)
Millage Rate×0.500×0.500×0.500

If in the fourth year the taxable value of the TIF grows from $800,000 to $1,200,000, due to redevelopment or the like, then the increment would increase to $200,000. If the millage rate was 0.500, the district’s revenue would be $100,000 in this year.

How Taxes Collected are Allocated Example

Whether a property is in a TIF district should not affect the property tax bill, only the distribution of the tax dollars when they are received.

The example shows two properties of equal value belonging to the same set of taxing jurisdictions, one located within the TIF district and one outside. This illustrates how the TIF district would get applied at the individual property level. The taxes collected are allocated differently, but both properties pay the same amount.

Property Appraisal Notices Coming from Department of Revenue

by

The Montana Department of Revenue is mailing notices to all owners of residential, commercial, industrial, and agricultural properties, showing their market and taxable values for the 2019-2020 appraisal cycle.

These notices are not tax bills. They include the department’s determination of market value for your property and will be used by your county treasurer to determine your property tax bills.

“It’s important that Montana property owners review this information thoroughly,” said Gene Walborn, Director of the Montana Department of Revenue. “If property owners wait until property tax bills are sent in November, it will be too late for the department to correct and update property characteristics that may impact the value of the property for the 2019 tax year. So please review the notice as soon as possible and contact us if you have questions.”

If property owners disagree with the department’s determination, they may submit a Request for Informal Classification and Appraisal Review (called Form AB-26) within 30 days of the date on their notice. Owners can electronically submit the form, download it, and find more information on our website.
