This page is for informational purposes only and is not tax, legal, or financial advice. Figures describe the median homeowner household in Ozaukee 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.
The rate gave way faster than almost anywhere
Between the 2020 and 2024 releases the median home value in Ozaukee County rose 33.5%, from $292,200 to $390,200. The effective rate fell 17.7% over the same span, a steeper move than in 75% of U.S. counties.
The median bill still rose 9.8%, to $4,631. 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 $4,216 to $4,631, a change of 10%. The comparison describes county-level medians only; individual assessments and bills can differ.
The heaviest band is also the fullest one here: 23,044 of 27,920 owner-occupied homes (82.5%) 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 4.8% 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.
What Ozaukee County Homeowners Actually Pay
The single largest group of Ozaukee County homeowners, 23,044 of 27,920 owner-occupied homes (82.5%), pays $3,000 or more a year. The median is one point in this spread, not a typical bill.
- Less than $800 1.0% (266)
- $800 to $1,499 2.2% (627)
- $1,500 to $1,999 2.5% (687)
- $2,000 to $2,999 11.2% (3,115)

A low rate, a bigger bill
Ozaukee County taxes property at 1.19%, roughly 16% below the Wisconsin average, and still bills a median $4,631, about 22% above the state figure. Because the effective rate is the bill divided by the home's value, that combination means local home values run well ahead of the state norm: a gentler rate applied to a larger base.

Property Tax History · PAR · HEAVY
| Year | Median Tax (vs prior release) | Effective Rate |
|---|---|---|
| 2024 | $4,631 +0.0% | 1.19% |
| 2023 | $4,629 +2.1% | 1.25% |

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 well above the national average of 0.92% puts Ozaukee County in the "Moderate" 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 Ozaukee County or any other county.

What tax filers report in Ozaukee County
Of the 47,800 federal returns filed from Ozaukee County in 2022, 5,020 (10.5% of filers) itemised and reported real estate taxes on Schedule A, averaging $8,433 each. The largest group was filers with adjusted gross income of $200k+, who accounted for 45% 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.
