Informational notice
Figures describe the median homeowner household in Williams 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
Williams County sits in the quarter of U.S. counties whose effective rate moved least over this span: 3.0% down, against a median home value that rose 11.8%.
A near-steady rate on a moving market passes that movement straight through: the median bill rose 8.4%, from $1,788 to $1,939.
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
Very little moved here between 2020 and 2024: the typical bill went from $1,788 to $1,939, a change of 8%. The comparison describes county-level medians only; individual assessments and bills can differ.
The heaviest band is also the fullest one here: 2,054 of 8,029 owner-occupied homes (25.6%) 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.
Top-quartile earnings meet a below-median rate, putting the median bill at 2.3% of median household income. Counties in this position span a wide range on the ratio above, because the dollar bill tracks home values rather than the rate.
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 Williams County Homeowners Actually Pay

Below North Dakota on both measures
Williams County's effective rate runs 31% under the North Dakota median and its bill 21% under. Both sitting on the same side means the gap is not a valuation artefact: a county can post a low rate purely because its homes are expensive, but then the bill rises to meet the state. Here it does not, so the $1,939 median bill reflects a genuinely lighter charge than the North Dakota norm rather than a different denominator. Compare it against the state page before reading anything into the county rank.

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.
