Informational notice
Figures describe the median homeowner household in Adams 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
Adams County sits in the quarter of U.S. counties whose effective rate moved least over this span: 0.4% up, against a median home value that rose 44.2%.
A near-steady rate on a moving market passes that movement straight through: the median bill rose 44.8%, from $2,046 to $2,962.
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 45% from $2,046 to $2,962. 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: 61,079 of 129,415 owner-occupied homes (47.2%) 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.
Top-quartile earnings meet a below-median rate, putting the median bill at 3.1% 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.
Adams County is an outlier inside Colorado
Across the 64 Colorado counties with a published rate, the average effective rate is 0.39%. Adams County is at 0.61%, which sits 2.2 standard deviations above that average. Fewer than one county in twenty nationally is this far from its own state's centre, so a state-level average is a poor guide to what is owed here.
Standard deviations are computed across every county in the state with a published effective rate for 2024; states with fewer than five such counties are not assessed.
What Adams County Homeowners Actually Pay

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.
