Inside Bentonville city limits and the Bentonville School District, the combined property tax rate is about 61.82 mills, according to the Arkansas Department of Finance and Administration’s most recent millage report.1Arkansas Department of Finance and Administration. 2024 Millage Report – 2025 Collections Arkansas taxes real estate at 20% of market value, so a $300,000 home has an assessed value of $60,000 and an annual tax bill of roughly $3,709 before credits. The homestead credit, authorized at up to $600 beginning with 2026 tax bills, pulls that figure closer to $3,100.2Arkansas Department of Finance and Administration. Property Tax Relief
Where the 61.82 Mills Come From
A mill equals one-thousandth of a dollar, so each mill costs you $1 for every $1,000 of assessed value. Three taxing authorities stack their rates on every parcel inside Bentonville:
- Bentonville School District (#6) at 46.8 mills. That includes the 25-mill statewide minimum for school operations, 0.8 mills for additional operating costs, and 21 mills for bond debt tied to school construction and improvements.
- Benton County at 9.7 mills, which funds the county general fund, county roads, and the public library system.
- City of Bentonville at 5.32 mills, split between 4.83 mills for general city operations and 0.49 mills for miscellaneous city expenses.
Add them up and you get 61.82 mills for parcels sitting inside both Bentonville city limits and the Bentonville School District.1Arkansas Department of Finance and Administration. 2024 Millage Report – 2025 Collections Your rate can differ if your parcel falls in a different school district boundary, which happens more often than people expect in Northwest Arkansas. Rates also shift when voters approve new bond issues or old ones expire.
Calculating Your Own Bill
Arkansas law requires all real and personal property to be assessed at 20% of market value.3Arkansas Department of Finance and Administration. Property Tax Frequently Asked Questions That ratio is the main reason Arkansas property tax bills look modest next to states that tax at full market value. A home the county appraises at $400,000 has an assessed value of $80,000.
From there, multiply the assessed value by your total millage rate. For a $400,000 home in Bentonville at 61.82 mills, the math runs $80,000 × 0.06182 = $4,946 before any credits. Apply the homestead credit of up to $600 for 2026 and the bill lands around $4,346.2Arkansas Department of Finance and Administration. Property Tax Relief
The Benton County Assessor sets your property’s market value and maintains an online database where you can look up your current appraisal and assessment history. The county’s next countywide reappraisal is scheduled for 2028, with another in 2032. Arkansas law requires counties to reappraise all real estate every four years to reflect current market conditions.4Benton County Arkansas. County-Wide Reappraisal 2028
The Credit and Caps That Actually Lower Your Bill
Two features of Arkansas law do most of the work in holding down what you pay in Bentonville. Both come out of Amendment 79.
Homestead Property Tax Credit
If the home is your primary residence, you qualify for an annual credit against your property tax bill. The Arkansas General Assembly authorized the credit at up to $600 beginning with 2026 tax bills, up from the previous $500.2Arkansas Department of Finance and Administration. Property Tax Relief You apply once through the Benton County Assessor’s office, and the credit then renews automatically. If your total bill is less than $600, the credit covers the full amount, but it can’t generate a refund.
Assessment Increase Caps
After a reappraisal, the assessed value of your homestead can rise by no more than 5% per year until it catches up to the new appraised value. Non-homestead property such as rentals, commercial buildings, and vacant land faces a 10% annual cap instead.5Justia Law. Arkansas Constitution Amendment 79 – Property Tax Relief In a market that’s appreciated as fast as Northwest Arkansas, the cap often creates a real gap between what the assessor says your home is worth and what you actually pay taxes on, sometimes for years after a reappraisal.
One wrinkle buyers often miss: a sale resets this. When title transfers, the county reassesses the property at 20% of appraised value at the next assessment date, and the 5% cap restarts from the new purchase price rather than the previous owner’s stepped-down value.6Benton County Arkansas. Assessors Office Reappraisal A recent buyer can pay noticeably more than a long-time neighbor with an identical house.
Senior and Disability Freeze
Homeowners 65 or older, or those who are permanently disabled, can freeze the assessed value of their homestead so it never increases in future reappraisals. The millage rate itself can still change, but the assessed value stays locked at whatever it was when you turned 65, became disabled, or purchased the home, whichever is lower.5Justia Law. Arkansas Constitution Amendment 79 – Property Tax Relief You’ll need to bring proof of age or disability to the Benton County Assessor to activate it.
When Taxes Are Due
Property taxes in Benton County are payable between the first business day in March and October 15. Anything unpaid after October 15 is delinquent, and the collector adds a 10% penalty to the outstanding balance.7Benton County Arkansas. Collectors Office Calendar Real estate taxes also accrue interest once delinquent. When October 15 falls on a weekend or postal holiday, the deadline rolls to the next business day. Active-duty military members deployed during the tax year receive an automatic extension through one full tax year after their deployment ends.
The Benton County Tax Collector accepts payments online, by mail, or in person. The online portal charges a processing fee that goes entirely to the payment processor; the county keeps none of it.8Benton County Arkansas. Benton County Collector – Payment Methods In-person payments can be made at the Benton County Administration Building or the Bentonville satellite office at 2401 SW D Street. Keep the receipt; you’ll need it when you renew a vehicle registration.
If your mortgage includes an escrow account, your lender collects property taxes monthly as part of your mortgage payment and pays the county on your behalf. Even then, confirming that the lender actually paid on time is worth the two minutes it takes, because late payments caused by lender errors still generate penalties on your account.
