Bentonville's housing stock splits in a way that matters for appeals. The neighborhoods around the downtown square and Crystal Bridges are older, smaller, and priced on land and location, which mass appraisal handles badly. The subdivisions pushing west and south are newer and largely built after the last cap reset, so their owners feel the full appraised value rather than a capped one. If you moved into a new build in the last few years, you are in the group where a reduction translates almost dollar for dollar into a lower bill.
Read your record for factual errors
Pull your parcel from the assessor's site and check the finished square footage, garage treatment, basement or bonus room classification, and year built. Fast-growing subdivisions get measured in volume, and a bonus room counted as finished living area is a common and easily corrected mistake.
Line up assessments on your own street
The county says outright that comparable properties in the same neighborhood assessed for less are an owner's best evidence. In a Bentonville subdivision where floor plans repeat, that comparison is unusually easy to make and unusually hard for the county to wave off.
See where the cap has you
Amendment 79 limits homestead taxable value to 5 percent growth a year. Newer buyers and new construction are usually taxed on the full appraised value, so a reduction reaches them immediately. Owners who have held the same Bentonville home since before 2024 are often taxed on a lower number, and for them a reduction pulls down the ceiling their bill is climbing toward each year.
Start with the informal review
Call the assessor's office in late July and ask for the appraiser covering your area. Bring the record errors and the neighborhood assessments. If they will not change the value, ask to be put on the board calendar before the August cutoff.
Take it to the board
There is no fee and no requirement that you appear. You can petition by letter, or have an agent do it. The board issues a written decision within 10 business days, and a denial can go to county court by the second Monday in October.
