Washington County, home to Fayetteville and 250k Arkansans, operates under Arkansas\'s constitutional 20% property tax system. Real property is assessed at 20% of fair market value (Arkansas Constitution Article 16 §15). Tax = AV × millage / 1,000. Amendment 79 (2000) provides three powerful homestead protections: (1) the universal $600 Homestead Property Tax Credit (effective 2026, post Act 330 of 2025); (2) a 5% annual cap on AV increases for homestead (10% for non-homestead); and (3) an AV freeze for owners 65+ or disabled. Effective rates run ~0.55-0.65% statewide median — among the lowest in the United States. Note: Arkansas pays property taxes ONE YEAR BEHIND — your 2026 assessment is billed in March/April 2027 with payment due October 15, 2027.
How the bill is built
Arkansas property tax follows a 4-step calculation. Step 1: Fair Market Value. The Washington County Arkansas Assessor determines FMV annually. Step 2: Apply 20% AR. AV = FMV × 20%. So a $200K home has AV = $40K. Step 3: Apply tax rate. Tax = AV × millage / 1,000. Washington County\'s combined millage is ~55 mills (= ~1.10% gross before homestead). Step 4: Apply $600 Homestead Property Tax Credit. Subtract up to $600 from the bill (no refund of unused credit). For homes producing tax bills under $600, the credit fully wipes out the property tax liability. Effective rate post-credit is ~0.55%.

Deductions and exemptions for 2026
Arkansas homeowner property tax relief is concentrated in three Amendment 79 mechanisms (passed by voters in 2000): (1) the universal $600 Homestead Property Tax Credit (effective 2026, post Act 330 of 2025), (2) the 5% annual AV cap for homestead (10% for non-homestead), and (3) the AV freeze for owners 65+ or disabled. Plus the FULL Disabled Veteran Exemption for 100% service-connected disabled vets.
$600 Homestead Property Tax Credit (Amendment 79 — universal)
The Homestead Property Tax Credit was established at $300 per homestead in 2000, raised to $350, then $375, then $425, then $500, and most recently to $600 effective 2026 (Act 330 of 2025). The credit is applied directly to the property tax bill — if your bill is below $600, no tax is due (but no refund of remaining credit). The credit is universal — no age, income, or other qualification beyond homestead status. Limit one homestead per taxpayer per calendar year. Apply with County Assessor.
5% / 10% Annual AV Cap (Amendment 79)
For homestead properties: taxable AV cannot increase more than 5% per year, regardless of how much FMV rises. For non-homestead (commercial, agricultural, vacant): 10% per year cap. Cap resets at sale (the new owner restarts with full FMV-based AV — the "Welcome Stranger" pop-up provision). Caps do NOT apply to newly-constructed property or substantial improvements. The cap has produced significant AV disparities in fast-growing markets like Northwest Arkansas (Benton/Washington counties), where long-term residents pay far less than recent buyers for identical homes.
Senior/Disabled AV Freeze (Amendment 79)
Owners 65+ or permanently disabled (any age) can apply for a true AV freeze — the AV is frozen at the level when first qualified. Note: the freeze does NOT cap millage rate increases (so tax bills can still rise if local taxing entities raise rates). The freeze does NOT transfer to new owners at sale. Combined with the universal $600 Homestead Credit, this provides among the most-favorable senior property tax structures in the central United States.
FULL Disabled Veteran Exemption (100% service-connected)
Arkansas provides a FULL property tax exemption on the homestead for veterans rated 100% service-connected disabled, OR who have lost/lost the use of one or more limbs, OR who are totally blind in one or both eyes from service-connected causes (Disabled Veterans Property Tax Exemption Act). Surviving unremarried spouses retain. Apply with County Assessor and County Collector.
Appealing your assessment
Arkansas property tax appeals follow a 3-tier process. Level 1: County Equalization Board. File written appeal by the third Monday in August each year. The Board holds informal hearings. Level 2: County Court. If unresolved, appeal to County Court within 30 days. Level 3: Arkansas Circuit Court. County Court decisions can be appealed to Circuit Court. Most Arkansas appeals are resolved at Level 1. Note: Arkansas pays property taxes ONE YEAR BEHIND — your 2026 assessment is billed in March/April 2027 with payment due October 15, 2027.
