Informational notice
Figures describe the median homeowner household in Petroleum 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 Petroleum County rose 29.4%, from $155,700 to $201,400. The effective rate fell 24.4% over the same span, a steeper move than in 92% of U.S. counties.
The median bill still fell 2.2%, to $1,211. 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
This is one of the counties where the typical bill came down, from $1,238 in 2020 to $1,211 in 2024, a fall of 2%. The source reports the change but does not distinguish among rate, value, or household-composition effects.
The largest reported group here falls at the bottom of the national range: 55 of 161 owner-occupied homes (34.2%) report annual real-estate taxes under $800. This distribution describes reported owner-occupied homes, not an affordability judgment for any property.
Both figures cluster near the middle of the national range, and the median bill comes to 2.0% of median household income. Counties like this are the reason a national average exists at all, and also the reason it explains so little.
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.
The published bill went DOWN here
Between the 2020 and 2024 ACS releases the median annual property tax in Petroleum County fell from $1,238 to $1,211, a change of -2.2%. Fewer than three counties in a hundred recorded any decline over this period; nearly everywhere else the published figure rose. A fall can reflect reassessment, a shifting mix of the homes surveyed, or genuine rate relief, and these estimates cannot separate those causes.

Below Montana on both measures
Petroleum County's effective rate runs 17% under the Montana median and its bill 55% under. Both sitting on the same side means the gap is not a valuation artefact: a county can post a low rate purely because its homes are expensive, but then the bill rises to meet the state. Here it does not, so the $1,211 median bill reflects a genuinely lighter charge than the Montana norm rather than a different denominator. Compare it against the state page before reading anything into the county rank.

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.

IRS county file: no disclosed Petroleum County Schedule A rows
The IRS county file records no returns reporting real estate taxes on Schedule A for Petroleum County. That is a limit of the published data rather than a finding about the county: county-level figures are withheld where the counts are too small to disclose safely, which is common in places with few filers. Roughly one county in sixteen is in this position, so the filer view available elsewhere on this site is simply not available here. Source: IRS Statistics of Income county data.
