Green Bay WI Property Tax Rate: Find It and Estimate Your Bill
Green Bay's median effective property tax rate is 1.50%, above the Wisconsin and national medians. Here is where to find the official Brown County rates and how to estimate a bill.
Your Green Bay, WI property tax rate is best read as a share of your home's value, not as the number printed on your bill. The median effective rate in Green Bay is 1.50%, compared with 1.43% for Wisconsin and 1.02% nationally [1]. That puts Green Bay above both benchmarks, so a typical owner here pays a larger share of home value in property tax.

An effective rate is the tax you pay divided by what your home is worth. It tells you how heavy the tax is relative to value, which makes it useful for comparing cities with different home prices. The rate on your bill is calculated differently, so the two figures are not interchangeable.
The 1.50% figure comes from a third-party estimate that does not state the tax year it covers. Treat it as a starting point. The official Brown County figures, covered next, show the rates that apply to your bill.
How are Brown County and Green Bay property taxes split?
Brown County publishes its tax rate details by tax year, and each year opens as a PDF. Because the rates are split by year, you pick the year that matches the bill you want to understand.
The City of Green Bay sends you to the county for those details. Its Property Taxes page says that details of the tax rates can be found on Brown County's Tax Rate Information web page [2]. Start on the city page, since it links you directly to the county records that hold the rate PDFs.
The same city page also links to a Tax Calculator [2]. The calculator is built to help you estimate what a bill could look like, so you can get a rough figure without doing the math yourself. Use it alongside the county PDF for the matching year, because the PDF is the published rate you are estimating from.
Here is the route from start to finish:
- Open the Property Taxes page on the city's website.
- Follow the link to Brown County's Tax Rate Information page.
- Choose the tax year you need and open its PDF.
- Open the city's Tax Calculator and enter your home's details to get an estimate.
The first two steps take you from the city to the county, and the last two give you a published rate and a quick estimate. Keep the PDF open while you use the calculator, so you can compare the two results side by side.
Where do you find the official tax rate for your year?
Start with Brown County's Tax Rate Information page, which holds the official rate details for Green Bay property. Rates are posted by tax year, so pick the right year before you read any figure.
- Open the Brown County Treasurer's Tax Rate Information page. The county's rate details are on this page, and the Green Bay city site points you back to it [2].
- Choose the tax year you need. Details of tax rates can be viewed in PDF format by choosing a tax year below [3]. The page lists 2025, 2024 and 2023 as options, and each one opens as its own PDF [3].
- Check the city's Property Taxes page. Green Bay's page includes a Tax Calculator and a link back to the county rates [2]. Use the calculator to get a rough estimate before you open the county PDF, so you know which year's figures to look up.
- Confirm the year on your bill. The newest year on the county page may not be the year your bill uses. Find the tax year printed on your bill, then open the PDF with that same year.
A bill covers one tax year, so a PDF for a newer year can list rates your bill does not use. Compare the year in the PDF's title with the year on your bill before you use any figure from it.
How can you estimate your property tax bill on a typical home?
Your estimate is simple: multiply your home's value by Green Bay's median effective rate of 1.50%. [1] That gives you a planning number for a typical home, not an exact bill.
- Find your home's value. Start with the assessed value on your own assessment notice. If you don't have one, use the market value you expect the home to sell for. Assessed and market values can differ, so use the assessed value when you have it.
- Multiply that value by the effective rate. At the 1.50% median, a $300,000 home works out to
$300,000 × 0.0150 = $4,500a year in property tax. [1] A $250,000 home would come to $3,750 a year, or about $312.50 a month. [1] - Compare your result with the official figures. Brown County's Tax Rate Information page holds the detailed county rates. [2] The city's Property Taxes page links to that county page and offers a Tax Calculator, so you can run your own address there. [2] Set the calculator's result beside your estimate and use the official number if the two differ.
The median is an estimate for the whole city, not a rule for every house. Use your estimate to plan your budget, and treat the official county and city figures as the numbers that count.
How does Green Bay compare with Wisconsin and the rest of the country?
Green Bay has a higher median effective property tax rate than both Wisconsin and the country as a whole, but the state gap is small and the national gap is not. Green Bay's median effective property tax rate of 1.50% is higher than the Wisconsin median of 1.43% and the national median of 1.02% [1].
The table compares each median with Green Bay's figure, using the same source for all three [1].
The gap versus the state is 0.07 percentage points. On a $300,000 home, that works out to about $210 a year, which is a small difference you would barely notice in a monthly budget [1].
The gap versus the national median is 0.48 percentage points. On the same $300,000 home, that comes to about $1,440 a year, a difference that matters more when you are comparing a move from another part of the country [1].
Green Bay is close to the Wisconsin figure, so other costs will likely shape your decision more than the state rate. Compared with the national median, though, the local rate adds a meaningful amount to yearly housing costs, so it belongs in your budget.

What mistakes should you avoid when reading a tax rate?
Three mistakes cause most wrong tax estimates: mixing up two kinds of rate, using an old year's document, and judging a city by one number. Avoid each one before you put a figure in a budget, because a small error in the rate becomes a large error on the bill.
Don't mistake an effective rate for the mill rate on your bill
An effective rate is tax paid as a share of home value, so it works for rough estimates and city comparisons. The mill rate is the rate used to figure your actual bill, so use it when you need an exact amount. Green Bay's median effective rate is 1.50%, higher than Wisconsin's 1.43% and the national 1.02% [1]. That figure is a share of value, so multiplying it by the wrong base will not reproduce the number printed on your bill.
Don't use last year's document for this year's bill
Brown County posts tax rate details as PDFs for each tax year, with 2025, 2024 and 2023 listed [3]. A file for a different year may show figures that do not match the bill you are holding. Find the file for the year printed at the top of your bill, and use only that one. Your arithmetic can be perfect and the estimate will still be wrong if the year is wrong.
Don't judge a city's tax burden from one statistic
A single median is a starting point, not a verdict. A city with a higher rate can still cost you less on a modest home than a lower-rate city costs on an expensive one. The dollar amount depends on both the rate and the home's assessed value, so read the bill and the value together. Only then can you compare Green Bay with another city in a way that fits your budget.
Where should you go next to check your own bill?
The one thing to remember is that Green Bay's median effective rate is 1.50% [1]. It is tax as a share of home value, not the rate printed on your bill. Use it to get a rough sense of the bill, nothing more.
Your next step is Brown County's Tax Rate Information page, where rates are posted as PDFs for each tax year [3]. Before you rely on any estimate, confirm the year on your bill and your home's value. Then check your numbers against the official figures for that year.
