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 Harrison County, IA

For anyone weighing a move to Harrison County, Iowa, the housing math leans toward affordability. Homes here carry a median value of $176,000, and the annual real-estate tax bill that goes with that runs about $2,325, based on an effective rate of 1.321%. That rate sits just above Iowa's statewide median of 1.319% and ranks 49th among the state's 99 counties, so buyers won't find a discount versus neighboring counties, though the gap is slim. Against the national median of 0.794%, however, Harrison County homeowners pay noticeably more per dollar of value. Local incomes help offset this: the median household earns $79,535, with per-capita income at $39,351, which keeps the tax bill within reach for many buyers. Communities like Logan, along with Little Sioux and Magnolia, offer small-town settings where that combination of lower home prices and steady earnings can stretch a budget further.

Frequently asked questions

What is the property tax rate in Harrison County, IA?
The effective rate is 1.32% — meaning the median tax bill equals about 1.32% of the median home value.
How much are property taxes on a median home?
On the median home ($176,000), the estimated annual bill is about $2,325.
Is Harrison 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 Harrison 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 Harrison County assessor within the local deadline, typically with comparable sales as evidence.
