This page is for informational purposes only and is not tax, legal, or financial advice. Figures describe the median homeowner household in Custer County as reported to the Census Bureau, your own bill can differ based on your parcel's assessed value, exemptions, special districts, and municipal overlays. Always consult your county assessor, tax collector, or a qualified professional before making decisions that depend on these numbers.
How to read this county's bill
The bill here climbed steeply over 2020-2024, up 38% from $2,087 to $2,879. 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: 1,734 of 3,809 owner-occupied homes (45.5%) 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.
Top-quartile earnings meet a below-median rate, putting the median bill at 3.4% of median household income. Counties in this position span a wide range on the ratio above, because the dollar bill tracks home values rather than the rate.
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 Custer County Homeowners Actually Pay
The single largest group of Custer County homeowners, 1,734 of 3,809 owner-occupied homes (45.5%), pays $3,000 or more a year. The median is one point in this spread, not a typical bill.
- Less than $800 6.6% (253)
- $800 to $1,499 12.7% (482)
- $1,500 to $1,999 13.2% (504)
- $2,000 to $2,999 17.1% (653)
- $3,000 or more 45.5% (1,734)

Property Tax History · UNDER · MID
| Year | Median Tax (vs prior release) | Effective Rate |
|---|---|---|
| 2024 | $2,879 +12.9% | 0.77% |
| 2023 | $2,549 +4.5% | 0.78% |
| 2022 | $2,439 +12.7% | 0.83% |
| 2021 | $2,165 +3.7% | 0.85% |
| 2020 | $2,087 | 0.90% |
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.
Tax Burden
Tax Affordability Score
An effective rate notably lower than the national average of 0.92% puts Custer County in the "Very Affordable" band for property tax burden.
How this score is calculated: a 1-10 scale derived mechanically from the ratio of this county's effective rate to the national average effective rate (0.92%) - a ratio at or below 0.5× scores 10, a ratio at or above 2.0× scores 1, with a linear scale between. It is a factual comparison of Census figures only, not a recommendation, quality rating, or endorsement of Custer County or any other county.

What tax filers report in Custer County
Of the 4,800 federal returns filed from Custer County in 2022, 260 (5.4% of filers) itemised and reported real estate taxes on Schedule A, averaging $6,846 each. The largest group was filers with adjusted gross income of $100-200k, who accounted for 31% of the county's reporting returns.
Two things this does not say. The amount is what filers reported, recorded before the $10,000 cap on combined state and local tax deductions applies, so it is not the amount deducted. And the share is of everyone who files a return, not of homeowners: most filers now take the standard deduction, so a minority itemise at all.
