Informational notice
Figures describe the median homeowner household in Piatt County as reported to the Census Bureau; your parcel can differ. Not tax, legal, or financial advice: check the county assessor or a qualified professional before decisions that depend on these numbers.
The rate held while the market moved
Piatt County sits in the quarter of U.S. counties whose effective rate moved least over this span: 2.5% up, against a median home value that rose 26.3%.
A near-steady rate on a moving market passes that movement straight through: the median bill rose 29.5%, from $2,522 to $3,265.
Effective rate is the published median bill divided by the published median home value, so the two multiply back to the bill exactly; the rate's movement here is derived from those two figures rather than read from the rounded published rate. Both are ACS 5-year survey estimates for the median owner-occupied household, compared across non-overlapping releases. They describe what the Census published, not a local policy, assessment, or exemption change.
How to read this county's bill
The bill here climbed steeply over 2020-2024, up 29% from $2,522 to $3,265. These ACS medians describe the reported change; they do not identify whether a levy, assessment, home value, or change in the responding households caused it.
The heaviest band is also the fullest one here: 3,198 of 5,875 owner-occupied homes (54.4%) report annual real-estate taxes above $3,000. That band has no upper edge in the source, so the county median understates the burden carried by the plurality rather than describing it.
Both figures are in the national top quarter, and the median bill still equals only 3.4% of median household income. A high rate on high earnings produces a large dollar figure, and only the dollar figure tends to get quoted; the ratio above is the other half.
The share above is the median annual bill divided by median household income, a ratio of two county-level medians rather than a household-by-household figure.
What Piatt County Homeowners Actually Pay
The single largest group of Piatt County homeowners, 3,198 of 5,875 owner-occupied homes (54.4%), pays $3,000 or more a year. The median is one point in this spread, not a typical bill.

- $800 to $1,499 9.5% (557)
- $1,500 to $1,999 9.5% (557)
- $2,000 to $2,999 20.6% (1,212)
- $3,000 or more 54.4% (3,198)

Among the highest-taxed counties in the country
At 1.81%, Piatt County sits in the top 4% of all U.S. counties by effective property-tax rate. That is the rate, not the bill: a high rate on a modest home can still produce a smaller cheque than a low rate on an expensive one, which is why the $3,265 median bill is the number to compare against another county.

Each row is a separate ACS 5-year release, and consecutive releases share four of their five survey years. The percentage beside each bill is therefore movement in the published estimate against the previous release, not a single year's tax change. The two releases largely describe the same households. For change over time, compare releases that do not overlap.
