Informational notice
Figures describe the median homeowner household in Custer 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 65% from $675 to $1,112. 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 largest reported group here falls at the bottom of the national range: 520 of 1,492 owner-occupied homes (34.9%) report annual real-estate taxes under $800. This distribution describes reported owner-occupied homes, not an affordability judgment for any property.
Incomes run above the national midpoint and the rate is in the lowest quarter, leaving the median bill at 1.6% of median household income. Both figures move in the same direction here, so the ratio above is not pulled in two directions the way it is in most counties.
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.
