Informational notice
Figures describe the median homeowner household in Montgomery 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
Montgomery County sits in the quarter of U.S. counties whose effective rate moved least over this span: 5.1% down, against a median home value that rose 24.4%.
A near-steady rate on a moving market passes that movement straight through: the median bill rose 18.0%, from $1,599 to $1,887.
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 $1,599 to $1,887, 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 heaviest band is also the fullest one here: 2,666 of 8,758 owner-occupied homes (30.4%) 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.
A top-quartile rate meets below-median earnings here, and the median bill reaches 3.0% of median household income. A rate ranking places this county by the rate alone; the ratio above is the figure that accounts for what is earned here.
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 Montgomery County Homeowners Actually Pay

Among the highest-taxed counties in the country
At 1.68%, Montgomery County sits in the top 6% of all U.S. counties by effective property-tax rate. That is the rate, not the bill: a high rate on a modest home can still produce a smaller cheque than a low rate on an expensive one, which is why the $1,887 median bill is the number to compare against another county.

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.
