Property Assessment

The Assessor of Properties Office is responsible for identifying and valuing all taxable property within Jefferson County.  The assessor’s office processes all recorded documents that transfer property, map any new property and update ownership and address information.  Other responsibilities include measuring new constructions, processing personal property forms, processing mobile home park forms and maintaining greenbelt records.  Reevaluations are required periodically by state law with the last one occurring in 2014 and the next one scheduled for 2019.

The current Assessor of Property is Ms. Susan Gaddis Gass.  Susan was elected in 2008 after several years as Chief Deputy with the Jefferson County Assessor’s Office.  She obtained her Tennessee Certified Assessor designation in 1997.

My goal is to maintain a friendly office with fair and accurate values. 

Listed below are some of my most frequently asked questions.  Please feel free to contact the Assessor’s Office at 865-397-3326.  The office is located on the 2nd floor in the Historic Jefferson County Courthouse;202 W. Main St.; Dandridge, TN 37725.  Our office hours are 8:00 a.m. – 4:00 p.m.




1.  Where can I find information about the assessed value of my property?

This information may be obtained by contacting the county assessor's office at (865) 397-3326 or, if you prefer to view your property record on line, you may do so at the Tennessee Comptroller site.

2. How are the county assessor's office and trustee's office related?
The county assessor is responsible for estimating the fair market value of your home or other property; the trustee's office is responsible for billing and collection of the property taxes.

3. What kinds of property are taxable?
Under Tennessee State law, two types of property shall be assessed and taxed:

Real property (real estate), which is land and improvements attached to the land (buildings, etc.) such as houses, mobile homes and outbuildings.  

Personal property means assets used in the operation of a business or industry such as: machinery, equipment, signs, furniture, and fixtures. Privately owned vehicles, household goods, furniture and personal effects are currently exempt from personal property tax.

4. How is the value of real property determined?
In the State of Tennessee, assessment for tax purposes means establishing the full market value of your land and its improvements. Three approaches may be used to determine real property value. They are market, cost and income approaches.

5. How is the value of personal property determined?
Self-reporting asset listing forms are mailed to the taxpayer in January. The business owner completes these forms by listing all equipment (owned or leased) that is being used to operate the business or industry. The age and cost of the equipment will be taken into consideration as means of establishing the appraised value. These forms should be returned to the assessor's office by March 1.

6. How am I notified of my property's value?
An assessment change notice is mailed each time your property is revalued for tax purposes. It shows both the previous and the new values.

7. Is property assessed at its full value?
Yes. The state constitution requires property be assessed at 100 percent of its fair market value.

8. What determines the amount of a property tax?
The assessed value per hundred multiplied by the property tax rate equals the annual property tax bill. The costs to operate our local government determine how much property tax the county will need.

9. What is the appeal process?
The taxpayer should contact the assessor's office at (865) 397-3326 to discuss the property's value. If a taxpayer decides to appeal this value, appointments may be made through the assessor's office. The appeal process begins in the county assessor's office by appearing before the Local Board of Equalization. This board meets annually during the first two weeks of June.
