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 gave way faster than almost anywhere
Between the 2020 and 2024 releases the median home value in Adams County rose 64.8%, from $228,500 to $376,500. The effective rate fell 28.3% over the same span, a steeper move than in 96% of U.S. counties.
The median bill still rose 18.1%, to $1,359. Where the rate drops this far and the bill rises anyway, what changed is the value the rate is applied to.
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
Bills rose across 2020-2024, from $1,151 to $1,359, a gain of 18%. This is a comparison of published ACS medians, not an explanation of a particular property's assessment or tax bill.
The fullest band here is the $800 to $1,499 range, holding 532 of 1,505 owner-occupied homes (35.3%). The band shows where the largest share of reported owner-occupied households falls; it is not an individual-bill estimate.
Household income sits in the second quarter nationally and the effective rate in the lowest, so the median bill takes 2.2% of median household income. Both figures point the same way, which is unusual enough that the ratio above is worth reading rather than assumed.
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 Adams County Homeowners Actually Pay
The single largest group of Adams County homeowners, 532 of 1,505 owner-occupied homes (35.3%), pays $800 to $1,499 a year. The median is one point in this spread, not a typical bill.

- $2,000 to $2,999 20.5% (308)

At 0.36%, Adams County sits in the lowest 5% of all U.S. counties by effective property-tax rate. A low rate does not by itself mean a low bill: the median here is $1,359, and what a homeowner actually pays depends as much on local home values as on the rate.

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.
