Property Tax and Proration Calculators

DISCLAIMER: City and County will vote on a tax rate in July of 2024. Certified tax rates must be approved by the State Board of Equalization.

Property taxes in Tennessee are calculated utilizing the following four components:

Appraised Value

Appraised values are developed each county-wide revaluation cycle using qualified, arms-length sales of land and improved property, the Marshall & Swift cost manual, or Income & Expense information in accordance with mass appraisal standards set forth in Tennessee law.

Assessment Ratio

The assessment ratio for each different class of property is established by the Tennessee Constitution, Art.2, § 28 and TCA 67-5-801 state law as follows:



 Real Property



Tangible Personal Property

RatioProperty Classification RatioProperty Classification
25%Residential/Farm 30%Commercial/Industrial
40%Commercial/Industrial 55%Public Utility
55%Public Utility   


Assessed Value

The assessed Value is calculated by multiplying the appraised value by the assessment ratio.

Tax Rate

The tax rate for each county and municipality is set by the County Commission or the City Council based on the amount of monies budgeted to fund the provided services. These tax rates vary depending on the level of services provided and the total value of the county’s tax base.

The current tax rates for 2024 are as follows:

  • County: $1.8320
  • City: $0.7488
  • Combined Rate: $2.58

Calculating Property Tax Example

The example below is for a typical residential property with an Appraised Value of: 
and the most recent Montgomery County Tax Rate of: 
$1.8320 per $100 of assessed value or .018320 


Step 1

Multiply the Appraised Value times the Assessment Ratio 
$100,000 X 25% = $25,000 
This gives you the property’s Assessment Value 



Step 2

Multiply the Assessment Value times the Tax Rate 
$25,000 X (1.8320/100) = $458 (rounded to nearest dollar) 
$25,000 X .018320 = $458 
This gives you the amount of the county property tax bill for this particular property. 


If your property is also in the city, follow the same steps, using the 2024 city tax rate of $0.7488 to figure your city property tax bill. 
The billing amount you receive on your actual tax bills may vary slightly based on the method used for rounding. 
The tax rates for the current tax year are established by the County Commission and City Council in July of that year. The best possible estimate of taxes made between January 1st and July is done by utilizing the tax rates from the previous year.
