What you'll pay, at a glance

Property taxes are the largest local tax most homeowners pay. The effective rate measures the real tax bill as a share of home value — a more useful number than the nominal “mill rate,” because assessment practices vary county to county.

How this is calculated

The effective property tax rate is the median real-estate tax bill divided by the median home value — both for owner-occupied homes, from the U.S. Census Bureau's American Community Survey (ACS 5-year estimates)1. Median income is also from the ACS1. Federal and state income-tax figures use IRS2 and Tax Foundation3 data.

About Ouachita County, AR

Ouachita County’s effective property tax rate of 0.514% matches Arkansas’s statewide median exactly, placing the county below the national median of 0.794%. Among Arkansas’s 75 counties, it ranks 40th, squarely in the middle of the pack. A median home value of $102,100 generates an annual real-estate tax bill of about $525, a figure shaped as much by the area’s lower property values as by its rate. Households here earn a median of $49,268, with per-capita income at $27,803. Communities such as Louann and Smackover sit within the county. The comparison with national figures signals that property taxes take a smaller share of value here than in much of the country, though the state-level match means Ouachita County offers no particular advantage over other Arkansas counties.

Frequently asked questions

What is the property tax rate in Ouachita County, AR?
The effective rate is 0.51% — meaning the median tax bill equals about 0.51% of the median home value.
How much are property taxes on a median home?
On the median home ($102,100), the estimated annual bill is about $525.
Is Ouachita County's rate high or low?

How does the effective rate differ from my mill rate?
A mill rate is the nominal levy per $1,000 of assessed value. The effective rate reflects what you actually pay after exemptions and assessments — it's the median tax bill as a share of median home value, so it better predicts your real cost.
Will a reassessment raise my tax bill?
Not necessarily. If your home's assessed value rises, your bill can go up, but only if the mill rate and exemptions stay flat. Contact the Ouachita County assessor's office to review your current assessment.
Can I appeal my property tax assessment?
Yes. Most counties allow an appeal when you believe the assessed value exceeds the market value. File with the Ouachita County assessor within the local deadline, typically with comparable sales as evidence.
