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 Dickinson County, IA

Dickinson County’s effective property tax rate of 0.925% sits well below Iowa’s statewide median of 1.319%, and the county ranks 98th out of 99 on that measure. Against the national median of 0.794%, however, it runs slightly higher. The median home value here is $270,700, producing an annual real-estate tax bill of about $2,503, while median household income reaches $75,432 and per-capita income $48,636. Those figures describe a lakeside county anchored by towns such as Arnolds Park, Lake Park, and Milford, where property taxes take a smaller share of home value than in most of Iowa. The near-bottom state ranking signals that local levies are unusually restrained by Iowa standards, though homeowners still pay a bit more than the average American relative to value.

Frequently asked questions

What is the property tax rate in Dickinson County, IA?
The effective rate is 0.93% — meaning the median tax bill equals about 0.93% of the median home value.
How much are property taxes on a median home?
On the median home ($270,700), the estimated annual bill is about $2,503.
Is Dickinson County's rate high or low?
Compare it to the state median of 1.32% 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 Dickinson 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 Dickinson County assessor within the local deadline, typically with comparable sales as evidence.
