Informational notice
Figures describe the median homeowner household in Sully 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.
How to read this county's bill
The bill here climbed steeply over 2020-2024, up 39% from $1,236 to $1,715. 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: 103 of 464 owner-occupied homes (22.2%) 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 the income and the rate here sit in the third quarter nationally, and the median bill is 2.4% of median household income. Two above-average figures pulling in opposite directions is why the rate on its own is a poor guide.
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.

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.

IRS county file: no disclosed Sully County Schedule A rows
The IRS county file records no returns reporting real estate taxes on Schedule A for Sully County. That is a limit of the published data rather than a finding about the county: county-level figures are withheld where the counts are too small to disclose safely, which is common in places with few filers. Roughly one county in sixteen is in this position, so the filer view available elsewhere on this site is simply not available here. Source: IRS Statistics of Income county data.
