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.

Yankton, the county's largest community, anchors a region where property taxes run somewhat heavier than the national norm. Buyers weighing a move here should expect a rate that is competitive locally but noticeably higher than what many parts of the country see.

Frequently asked questions

What is the property tax rate in Yankton County, SD?
The effective rate is 1.06% — meaning the median tax bill equals about 1.06% of the median home value.
How much are property taxes on a median home?
On the median home ($225,900), the estimated annual bill is about $2,388.
Is Yankton 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 Yankton 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 Yankton County assessor within the local deadline, typically with comparable sales as evidence.
