Informational notice
Figures describe the median homeowner household in Merrimack 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 Merrimack County rose 49.8%, from $245,400 to $367,600. The effective rate fell 22.3% over the same span, a steeper move than in 89% of U.S. counties.
The median bill still rose 16.3%, to $6,783. 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 $5,831 to $6,783, a gain of 16%. This is a comparison of published ACS medians, not an explanation of a particular property's assessment or tax bill.
The heaviest band is also the fullest one here: 38,698 of 44,754 owner-occupied homes (86.5%) 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.
Both figures are in the national top quarter, and the median bill still equals only 7.0% of median household income. A high rate on high earnings produces a large dollar figure, and only the dollar figure tends to get quoted; the ratio above is the other half.
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.

Among the highest-taxed counties in the country
At 1.85%, Merrimack County sits in the top 4% of all U.S. counties by effective property-tax 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.
