Office Vision Statement

To embrace a progressive approach to enhance office operation.

I, along with my clerks: Ms. Jacqueline Good, Mrs. Amanda Barber, Ms. Shanita Earls, and Ms. Danielle Rankin hold steadfast to our ultimate quest which is: “To Serve and To Serve Well”. 

 The Office of Tax Assessor/Collector is the sector of county government that performs the duty of property taxation in compliance with state law according to the rules and regulations set forth by the Mississippi Department of Revenue (MS DOR).

Property taxation can be categorized as an annual tax based on ownership or possession of property. Property taxation is the major source of revenue, whereby county governments are able to provide the essential building blocks that create healthy, vibrant, and safe communities.

The Tax Assessor’s responsibility is to discover, list, and value taxable property within a jurisdiction.  Residential real property, nonresidential real property, personal property, public utilities, and motor vehicles are the five property classifications that are valued for ad valorem taxes.

Real and personal property is valued at the county level in accordance with MS DOR guidelines; public utilities and motor vehicles are valued at the state level.  In addition, the applications for homestead exemption (tax credits that are given to homeowners) are filed in the Assessor’s Office.

The Tax Collector’s responsibility is to collect all tax dollars within a jurisdiction and to settle monies to the proper entity; settlements are distributed to state, county, public school, and city in support of the various entities’ budget.

Claiborne County CourthouseThe main tax collection is ad valorem taxes; other collections include sales tax, use tax, additional motor vehicle fees, mobile home registration/certification and privilege license fees. All monies collected are settled by the 20th of each month for the preceding month.
