Assessor's Office Millage & Tax Calculator

Department Menu
WEB DEV NOTE: Uses custom template form

It is important to note, the Benton County Assessor’s Office does not value your personal property. The values placed on your personal property when you assess your vehicles each year are supplied by the State of Arkansas, based on information and data they receive from a national vendor they contract with to supply those values.

On August 12, 2019, Benton County, along with the other 74 counties in Arkansas, was notified by the Arkansas Assessment Coordination Department in Little Rock that certain new and used auto and light truck values provided to the counties in January 2019 were incorrect. Your revised assessment reflects the updated and correct market value for the 2019 assessment year.

If you would like to calculate how this revision will affect your 2019 personal property tax, billed and payable in 2020, use our tax calculator to figure the difference in your 2019 tax liability.

We appreciate your patience and understanding through this process. Please know that it is a necessary step to ensure that the operating revenue for our school districts and municipalities does not suffer as a result of the incorrect values.
