- Ark. Code Ann. §26-27-317
Arkansas law gives homeowners three specific grounds to seek a lower assessment before the Sebastian County Equalization Board: the property is assessed higher than comparable neighboring properties (equalization), the assessment is clearly erroneous, or it is manifestly excessive compared with actual selling prices (Ark. Code Ann. §26-27-317). If similar homes around Fort Smith and Greenwood carry lower assessments than yours, the equalization ground exists for exactly that situation.
Petitions are due on or before the third Monday in August — Monday, August 17, 2026 — by 4:30 p.m., and the board can only adjust the current year's assessment, so a missed deadline means waiting a full year. Filing logistics vary by county; your county clerk's office can confirm the details.
How to appeal in Sebastian County — step by step
- 1
Pull your assessment and your neighbors' assessments
Assessment records are public. Compare your home's assessed value against genuinely similar homes nearby — same neighborhood, similar size and age.
- 2
Match your evidence to a statutory ground
Arkansas boards can reduce a value only on the three enumerated grounds: assessed higher than comparable neighbors, clearly erroneous, or manifestly excessive versus selling prices. Frame your evidence around the one that fits.
- 3
File before August 17, 2026, 4:30 p.m.
Contact the Sebastian County clerk's office to schedule your equalization-board petition — procedures vary by county, and the 4:30 p.m. third-Monday-in-August cutoff is statutory.
- 4
Present your case
The burden of proof is on you — the assessor's value stands unless you show it's inaccurate under one of the three grounds. Bring your comparison table and any supporting records.
- 5
Preserve your right to go further
If you disagree with the board's decision, an appeal to county court must be filed with the county clerk (on or before the second Monday in October) — and you must have gone through the equalization board first.

When is the deadline to appeal property taxes in Sebastian County in 2026?
2026 petitions to the Sebastian County Equalization Board are due on or before the third Monday in August — Monday, August 17, 2026 — by 4:30 p.m. (Ark. Code Ann. §26-27-317). Filing logistics vary by county, so confirm the details with your county clerk's office.
What does it cost to file?
Confirm with your county clerk when you schedule your hearing — the petition is an administrative filing handled through the county.
What arguments can the board actually consider?
Three statutory grounds only: your property is assessed higher than comparable neighboring properties (equalization), the assessment is clearly erroneous, or it is manifestly excessive compared with actual selling prices. Evidence that doesn't fit one of them won't move the board.
What if I miss the August deadline?
The equalization board can only adjust the current meeting year's assessment, so a missed deadline means waiting for next year's board — set a reminder for July so you have time to build the comparison.
