Informational notice
Figures describe the median homeowner household in Mercer 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
Mercer County sits in the quarter of U.S. counties whose effective rate moved least over this span: 1.5% down, against a median home value that rose 28.6%.
A near-steady rate on a moving market passes that movement straight through: the median bill rose 26.6%, from $1,836 to $2,325.
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 27% from $1,836 to $2,325. 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: 4,252 of 13,053 owner-occupied homes (32.6%) 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.
Earnings are in the national top quarter and the rate is above the midpoint, so the median bill represents 3.0% of median household income. A headline bill conflates the dollar figure with the proportion; the two come apart here, and the ratio above is the second of them.
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 Mercer 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.
