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 Bennett County, SD

Bennett County’s effective property tax rate of 0.981% sits just under South Dakota’s statewide median of 1.014%, placing it 38th among the state’s 66 counties. Against the national median of 0.794%, however, the county runs noticeably higher. That gap matters because the local tax bill is calculated on a median home value of $156,400, producing an annual real-estate tax of about $1,535. With median household income at $53,750 and per-capita income at $18,895, property taxes take a meaningful bite out of earnings in and around Martin, the county’s largest town. The picture is one of a county that looks average within South Dakota but costs more than much of the country, a signal that homeowners here carry a somewhat heavier property tax load than national figures alone would imply.

Frequently asked questions

What is the property tax rate in Bennett County, SD?
The effective rate is 0.98% — meaning the median tax bill equals about 0.98% of the median home value.
How much are property taxes on a median home?
On the median home ($156,400), the estimated annual bill is about $1,535.
Is Bennett County's rate high or low?
Compare it to the state median of 1.01% and the national average near 1.1%.
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 Bennett 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 Bennett County assessor within the local deadline, typically with comparable sales as evidence.
