Informational notice
Figures describe the median homeowner household in Slope 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 Slope County rose 86.8%, from $91,000 to $170,000. The effective rate fell 42.5% over the same span, a steeper move than in 100% of U.S. counties.
The median bill still rose 7.5%, to $387. 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
Very little moved here between 2020 and 2024: the typical bill went from $360 to $387, a change of 8%. The comparison describes county-level medians only; individual assessments and bills can differ.
The largest reported group here falls at the bottom of the national range: 151 of 302 owner-occupied homes (50.0%) report annual real-estate taxes under $800. This distribution describes reported owner-occupied homes, not an affordability judgment for any property.
Incomes run above the national midpoint and the rate is in the lowest quarter, leaving the median bill at 0.5% of median household income. Both figures move in the same direction here, so the ratio above is not pulled in two directions the way it is in most counties.
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.
Paying off the mortgage changes the picture here
29.2% of Slope County homes owned free and clear (71 of 243) report no property tax at all, against 0.0% of homes still carrying a mortgage. A reported zero is not proof of an exemption: it can equally mean a bill paid by another party, or a reporting artefact. But a gap this size is where age- and disability-based relief usually shows up, because those programmes reach owners who have finished paying.
Slope County is an outlier inside North Dakota
Across the 53 North Dakota counties with a published rate, the average effective rate is 0.88%. Slope County is at 0.23%, which sits 2.7 standard deviations below that average. Fewer than one county in twenty nationally is this far from its own state's centre, so a state-level average is a poor guide to what is owed here.
Standard deviations are computed across every county in the state with a published effective rate for 2024; states with fewer than five such counties are not assessed.
What Slope County Homeowners Actually Pay
The single largest group of Slope County homeowners, 151 of 302 owner-occupied homes (50.0%), pays less than $800 a year. The median is one point in this spread, not a typical bill.
- Less than $800 50.0% (151)
- $800 to $1,499 5.3% (16)
- $1,500 to $1,999 1.7% (5)
- $2,000 to $2,999 9.6% (29)
- $3,000 or more 9.9% (30)

Among the lowest-taxed counties in the country
At 0.23%, Slope County sits in the lowest 1% 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 $387, 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.

IRS county file: no disclosed Slope County Schedule A rows
The IRS county file records no returns reporting real estate taxes on Schedule A for Slope 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.
