Benton County · Centerton
Most Centerton homes are new enough that Arkansas's tax cap has not built up any cushion. Whatever the county says your house is worth is what you pay on.

File with: Benton County Board of Equalization
Centerton has been one of the fastest-growing cities in Arkansas, and its housing is overwhelmingly recent. That matters more than it sounds. Amendment 79 caps how fast a homestead's taxable value can rise, but the cap only builds a cushion over years of ownership, and new construction enters the roll uncapped. Long-tenured owners elsewhere in Benton County often find a reduction lowers the ceiling their bill is climbing toward rather than the bill itself. In Centerton, most owners do not have that gap, so a correction shows up in what they actually pay.

Centerton parcels ran about 61.9 mills in the state's 2025 millage report, roughly 1.24 percent of market value. Subdivisions here were built fast and in volume, which is exactly the condition under which mass appraisal generalizes. A whole phase can get valued off the same base model, so a house with a smaller lot, a worse orientation, an unfinished bonus room, or a builder's entry-level trim package ends up carrying the value of the upgraded version next door. Those differences are documented in your own closing file.
Compare the record to your build sheet
Get the county's property record and put it next to the specification sheet from your builder. Square footage, finished versus unfinished bonus space, garage bays, covered patio treatment, and lot size are the fields that most often disagree.
Price your plan against the same plan nearby
In a phase where floor plans repeat, comparison is unusually clean. Pull record cards for the same model on your street. If yours is assessed higher without a corresponding upgrade, that difference is your case.
Bring your closing statement if you bought below the value
A recent arm's length purchase price below the county's appraised value is direct market evidence. Arkansas does not reset your value to the sale price automatically, so the county may still be carrying a number your own transaction contradicts.
Call the assessor in late July
The informal review runs before the board. Ask for the appraiser assigned to Centerton, walk through the record differences, and ask what would need to change for them to adjust the value.
Petition the board by August 17
