Dane County, WI tax records are public and free to search online through the county’s AccessDane portal. You can look up any parcel by its Parcel Identification Number, the owner’s name, or the property address, and see the assessed value, current and past tax bills, payment history, and how the total was calculated. Wisconsin’s public records law means you don’t need a reason or the owner’s permission to view this information.
How to Search AccessDane
The fastest lookup is by Parcel Identification Number. Dane County recently switched to a longer PIN format that adds a three-digit municipal code to the front of the old number, so a parcel that used to read “14-0610-8660-8” now reads “028-0610-013-8660-8.”1Dane County Register of Deeds. Register of Deeds – Parcel Info You can find the PIN on a prior tax bill or on a recorded deed.
Without a PIN, the AccessDane portal accepts owner name or address searches.2Dane County Land Information Council. Access Dane These searches sometimes return more than one result, especially for common names or subdivided lots, so confirm the parcel details before relying on what you find.
Once you open a parcel, look for links labeled “Tax Summary” or “Tax History” to see current and past billing data. The page also shows the legal description and geographic information, which helps verify you’re looking at the right property.
What a Dane County Tax Record Shows
Each record breaks down how the county arrived at the annual bill. The assessed value appears prominently, reflecting the property’s estimated fair market value as determined by the local assessor under Wisconsin’s valuation standards.3Wisconsin State Legislature. Wisconsin Code 70.32 – Real Estate, How Valued Under state law, the tax roll must identify each parcel, list the owner’s name and address, and show the total taxes levied by every taxing jurisdiction the property falls under.4Wisconsin State Legislature. Wisconsin Code 70.65 – Content of Tax Roll
Those jurisdictions typically include the municipality, county, school district, and technical college district, each taking a share of the total levy. The record shows the gross tax (the raw amount based on the combined mill rate) and the net tax (what you actually owe after state credits). Two credits appear on nearly every Dane County residential bill: the Lottery and Gaming Credit, which uses state lottery revenue to reduce property taxes on a primary residence,5Wisconsin Department of Revenue. Wisconsin Lottery and Gaming Credit Program and the First Dollar Credit, a flat reduction for all improved residential property.6Wisconsin Department of Revenue. First Dollar Credit
Special Assessments and Special Charges
Records may also show line items beyond standard property taxes. A special assessment covers the cost of public improvements that benefit your property, such as road reconstruction or sewer installation. A special charge covers the cost of services provided to the property, like weed removal or storm water management.7Wisconsin State Legislature. Wisconsin Code 74.01 – Definitions The total bill equals net property taxes plus any special assessments and special charges combined.8Dane County Treasurer Office. Property Tax 101
Getting Copies of Tax Bills and Receipts
You can print or save any tax bill directly from AccessDane. Select the year you need, then use the print or PDF option. The generated document shows the assessed value, taxes levied, credits applied, and payment history for that year.
If you need a certified copy with an official stamp (some lenders and real estate transactions require this), contact the Dane County Treasurer’s office at the City-County Building, 210 Martin Luther King Jr. Blvd., Room 116, in Madison.2Dane County Land Information Council. Access Dane
Paying Property Taxes
Wisconsin gives owners two options for the annual bill: pay in full by January 31, or split into two equal installments due January 31 and July 31. If the total tax on the parcel is less than $100, the whole amount must be paid by January 31.9Wisconsin State Legislature. Wisconsin Code 74.11 – Dates for Payment of Taxes, Special Assessments and Special Charges
Where you send the payment depends on when. In December and January, current-year taxes go to your local municipal treasurer, not the county. After February, Dane County collects on most properties. The City of Madison is the exception: the Madison Treasurer handles current-year taxes through July 31, and the county takes over after that.10Dane County Treasurer Office. Pay Property Taxes Online
The county accepts online payments through AccessDane after February 20 each year. Two methods are available:
- E-check from a standard checking account: $1.50 flat fee. The portal defaults to credit card, so you have to switch to e-check on the payment screen.
- Credit or debit card: 2.39% of the payment or $1.50, whichever is greater. Debit cards are processed as credit and carry the same percentage fee.
The county does not accept savings account transfers, ACH transfers, or wire transfers for real estate tax payments.11Dane County Treasurer’s Office. Pay Property Taxes Online
When Taxes Go Unpaid
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 in July: miss July 31 by more than five working days, and the full unpaid amount becomes delinquent as of August 1.9Wisconsin State Legislature. Wisconsin Code 74.11 – Dates for Payment of Taxes, Special Assessments and Special Charges When either deadline falls on a weekend, the five-day grace period runs through the following Friday.
Delinquent taxes accrue interest at 1% per month or any fraction of a month, running from February 1 of the year they became delinquent. County boards can add up to 0.5% per month on top, for a combined rate that can reach 18% per year. After February 1, delinquent real property taxes go to the county treasurer rather than the municipal treasurer.12Wisconsin State Legislature. Wisconsin Code 74.12 – Settlement, Payment of Delinquent Taxes
If taxes stay unpaid, the county eventually obtains a tax certificate on the property. Two years after that certificate is issued, the county can begin proceedings to take ownership through a tax deed.13Wisconsin State Legislature. Wisconsin Code 75.521 – Tax Certificate and Tax Deed Proceedings The Dane County Treasurer’s office runs those auctions when properties reach that stage.14Dane County Treasurer Office.

Disputing the Assessed Value
If the assessed value on the record looks too high, there are two chances to push back before the number locks in for the year. The process starts informally and escalates to a formal hearing, and the deadlines are strict.
Open Book
Open Book is an informal window where you sit down with the assessor and discuss the assessment. In the City of Madison, the 2026 Open Book period runs May 4 through May 8.15City of Madison, WI. Open Book and Assessment Appeals Other municipalities set their own dates. Many disputes end here: if the assessor agrees they used incorrect data, the value can be corrected on the spot.8Dane County Treasurer Office. Property Tax 101
Board of Review
If Open Book doesn’t resolve things, the next step is a formal objection to the Board of Review. You must give the Board’s clerk written or oral notice at least 48 hours before its first scheduled meeting, then file a written objection within the first two hours of that meeting.16Wisconsin State Legislature. Wisconsin Code 70.47 – Board of Review In the City of Madison, the filing deadline for 2026 is 4:30 p.m. on May 15. Miss it and you’ll need a waiver, which the Board grants only for extraordinary circumstances.15City of Madison, WI. Open Book and Assessment Appeals
The objection uses state form PA-115A. You provide your opinion of the property’s value and explain why the assessment is wrong. If you bought, sold, remodeled, or had the property appraised in the last five to ten years, expect to supply those details too.17Wisconsin Department of Revenue. Objection to Real Property Assessment Hearings happen under oath, and you must fully disclose all your assessable property in the district. Comparable sales, an independent appraisal, or specific errors in the assessor’s records are what typically carry an appeal. Once the Board of Review wraps up, it’s generally too late to challenge the assessed value for that tax year.8Dane County Treasurer Office. Property Tax 101
Updating the Mailing Address on a Record
If you’ve moved or want tax bills sent elsewhere, submit the change directly to the Dane County Treasurer’s office in writing or through the county’s online system. The update applies to the tax billing system and may not carry over to other county departments like the Register of Deeds. Confirm the change was processed before the next billing cycle so a bill doesn’t go missing and start racking up interest.
