Brown County tax records are available to anyone through the county’s online land records portal. A search by parcel number, street address, or owner name pulls up the property’s assessed value, tax history, current balance, and a printable copy of the tax bill. Homeowners use the records to confirm what they owe, buyers check them before closing, and title and legal work often require a printed copy of the bill itself.
What a Property Record Shows
Each parcel record splits the assessed value into two parts: the land and any structures on it. The combined figure is the assessor’s estimate of fair market value, meaning what the property would sell for under normal conditions. Wisconsin law requires every municipality to make its assessment rolls available for public examination, with the local assessor present for at least two hours during that window to answer questions.1Wisconsin State Legislature. Wisconsin Code 70.45 – Return and Examination of Rolls
Beyond the valuation, the record lists the tax levy from each local jurisdiction that taxes the parcel. In Brown County that might be the City of Green Bay, the Village of Ashwaubenon, or another municipality, plus the school district and the county itself. Special assessments for utility improvements or recycling charges show up as separate line items on top of the base tax. The current payment status and any outstanding balance appear prominently, so you can tell at a glance whether a property is paid up or delinquent.
How to Search the Portal
The fastest search is by parcel identification number, which appears on any prior tax bill and on the recorded deed. Parcel number formats are not standardized across Wisconsin, so don’t assume a particular length or pattern.2Department of Revenue. State of Wisconsin Municipality Parcel Formats
If you don’t have the parcel number, search by street address or owner name. A small trick for address searches: enter the house number and street name only, without “Street,” “Avenue,” or similar suffixes. The database may abbreviate suffixes differently than you expect, and leaving them off avoids a false mismatch.
The results list opens into a detail view with tabs for different categories of information. The tax tab shows past payments and current obligations. The assessment tab breaks the value into land and improvement components and shows how the assessor arrived at each.
Printing a Tax Bill or Receipt
If you need a paper copy for a mortgage closing, a court filing, or your own records, the portal lets you generate a PDF of the original tax bill. The digital copy is identical to the printed bill the county mails. For most purposes you’ll never need to visit the Treasurer’s office in person to get one.
Paying Taxes Through the Portal
Brown County accepts property tax payments online through a third-party processor. An e-check costs $1.25 per transaction, a Visa debit card costs $3.95, and other credit and debit cards are charged 2.55% of the payment amount.3Brown County, Wisconsin. How to Pay Property Taxes Online On a $4,000 bill the card fee comes to about $102, so e-check is the clear choice if you’re paying online.
You can also mail a check to the Brown County Treasurer at PO Box 23600, Green Bay, WI 54305, or pay in person at the county courthouse. For mailed payments the postmark date controls the deadline. Payments made on or before January 31 go to your local municipal treasurer; payments after that date go to the county treasurer instead.4Wisconsin State Legislature. Wisconsin Code 74.11 – Dates for Payment of Taxes, Special Assessments and Special Charges
Payment Deadlines and Late Penalties
Wisconsin offers two ways to pay real property taxes. You can pay the full amount by January 31, or split it into two equal installments with the first due January 31 and the second due July 31. If your total bill is under $100 the installment option is off the table — the full amount is due by January 31.4Wisconsin State Legislature. Wisconsin Code 74.11 – Dates for Payment of Taxes, Special Assessments and Special Charges
Missing a deadline is expensive. If the first installment isn’t received within five working days after January 31, the entire remaining balance becomes delinquent as of February 1. The same rule applies to the July 31 deadline: anything unpaid five working days later becomes delinquent as of August 1.4Wisconsin State Legislature. Wisconsin Code 74.11 – Dates for Payment of Taxes, Special Assessments and Special Charges
Delinquent taxes accrue interest at 1% per month, calculated back to the preceding February 1. The county board may impose an additional penalty of up to 0.5% per month by ordinance.5Wisconsin State Legislature. Wisconsin Code 74.47 – Interest and Penalty on Delinquent Taxes At the maximum combined rate that works out to 18% per year.
Credits That Should Already Appear on the Bill
Several Wisconsin credits are applied automatically and show as reductions on the record. Reviewing them is a quick way to check that the bill is correct.
Lottery and Gaming Credit
Wisconsin residents whose property is their primary home as of January 1 get the lottery and gaming credit as a direct reduction on the tax bill. The amount changes every year because it’s funded by Wisconsin Lottery, pari-mutuel betting, and bingo revenue. The Department of Revenue sets a maximum credit value each November and multiplies it by the school district tax rate to produce the credit for a given parcel.6Department of Revenue. DOR Wisconsin Lottery and Gaming Credit Program It cannot be claimed on rental property, business property, or vacant land.
First Dollar Credit
Every taxable Wisconsin parcel with a building or other real property improvement qualifies for the First Dollar Credit, whether residential, commercial, or agricultural. The only requirement is that the improvement value on the parcel is greater than zero. This one is split equally across the installment payments.7Department of Revenue. DOR First Dollar Credit
Homestead Credit
The homestead credit is income-based and claimed on your state tax return rather than through the county. You must be a Wisconsin resident for the full year, at least 18, and have household income under $24,680, plus meet one additional condition such as having earned income, being disabled, or being 62 or older. The maximum credit is $1,168.8Department of Revenue. Homestead Credit Nobody applies it for you, so it’s easy to miss.
Veterans and Surviving Spouses Credit
Wisconsin veterans with a 100% service-connected disability rating from the VA qualify for a credit covering the full property tax on their primary residence, including up to one acre of land. The veteran must have entered active duty as a Wisconsin resident or lived in the state for at least five consecutive years afterward. Unremarried surviving spouses of qualifying veterans can also claim it.9Wisconsin Department of Veterans Affairs. Veterans and Surviving Spouses Property Tax Credit
If the Assessment Looks Wrong
If the assessed value in the record looks too high, Wisconsin law lets you challenge it before the local Board of Review. The deadlines are strict.
You must notify the Board of Review clerk, either orally or in writing, at least 48 hours before the board’s first scheduled meeting that you intend to object. The formal written objection must then be filed with the clerk within the first two hours of that first meeting. The objection form requires your own estimate of value, and you have to object to the total assessed value of the parcel as a whole rather than challenging the land or improvement portion alone.10Wisconsin State Legislature. Wisconsin Code 70.47 – Boards of Review
At the hearing the board starts from the presumption that the assessor’s valuation is correct, and you carry the burden of overcoming it with evidence. Comparable sales, a recent appraisal, or documentation of property defects are the strongest material to bring.11Department of Revenue. Guide for Board of Review Members If the board rules against you, further appeal runs to the Wisconsin Department of Revenue or to court, with court actions generally due within 90 days of notice of the board’s decision.
What Unpaid Taxes Lead To
Ignoring a Brown County tax bill eventually costs you the property. Once interest and any penalty start running, the county issues a tax certificate representing its legal claim on the unpaid taxes. If the taxes remain unpaid for roughly two years after the certificate is issued, the county can begin an in rem foreclosure proceeding under Wisconsin Statute 75.521. The county files a petition in court and publishes notice of the affected properties, and state law requires a redemption period of at least eight weeks during which the owner can pay all delinquent taxes, interest, penalties, and charges to save the property. If nobody redeems it in that window, the court grants a foreclosure judgment and ownership transfers to the county, wiping out all prior ownership interests, liens, and mortgages.
The full timeline runs roughly two to three years, but the financial damage starts on day one. If you’re having trouble paying, call the Brown County Treasurer’s office early; a payment arrangement is far cheaper than years of compounded interest.
