How Property Tax Works

Door County's property tax system funds essential local services including schools, county operations, municipal services, and special districts throughout Wisconsin's scenic "thumb" peninsula. Property taxes are collected by the Door County Treasurer and distributed to various taxing jurisdictions based on where your property is located within the county.

The effective property tax rate in Door County typically ranges from approximately 1.8% to 2.4% of assessed value, though this varies significantly by municipality and special taxing district. Your actual rate depends on your specific location, as properties may be subject to additional levies from school districts, fire districts, sanitary districts, and other local governmental units. The county assesses all real property annually at full market value, with no assessment cap limitations under Wisconsin law.

Door County encompasses 19 townships and 10 incorporated municipalities, each with potentially different tax rates due to varying local levies and special district assessments. This means two properties with identical assessed values may have different tax bills depending on their precise location and the services provided in that area.

When Are Property Taxes Due?

For the 2025/2026 tax year in Door County, property taxes are due in two installments:

Pro tip: If you pay through mortgage escrow, your lender splits these payments across your monthly mortgage. If you pay directly, set calendar reminders to avoid late penalties.
Section 4

Supplemental Tax Bills

Supplemental taxes in Door County are typically triggered by new construction, major improvements, or changes in property use that occur after the annual assessment date (January 1st). Unlike some states, Wisconsin generally incorporates these changes into the following year's regular assessment rather than issuing mid-year supplemental bills.

When new construction is completed or substantial improvements are made after January 1st, the additional value is usually added to your assessment for the following tax year. For example, if you complete a home addition in June 2025, the increased value would typically be reflected in your 2026 property tax bill rather than creating a supplemental assessment for 2025.

The calculation is based on the added assessed value multiplied by your property's total tax rate. If your addition increases your assessed value by $50,000 and your total tax rate is 2.2%, this would add approximately $1,100 to your annual tax bill beginning the following tax year.

Escrow & Property Taxes

Most mortgage lenders in Door County require borrowers to maintain an escrow account for property taxes when the loan-to-value ratio exceeds 80%. Your lender collects monthly escrow payments as part of your mortgage payment and pays your property taxes directly to the Door County Treasurer when due.

Property taxes in Door County are due January 31st for full payment, or can be split with first installment due January 31st and second installment due July 31st. Lenders typically pay the full amount by the January 31st deadline to avoid any interest charges. Your lender should provide an annual escrow analysis showing tax payments made on your behalf.

You can verify that your lender has paid your taxes by checking with the Door County Treasurer's office at (920) 746-2200 or visiting their website. If you pay your own taxes (no escrow), you're responsible for making payments directly to: Door County Treasurer, 421 Nebraska Street, Sturgeon Bay, WI 54235. Online payment options are available through the county's website.

Frequently Asked Questions

Q: When are Door County property taxes due for 2025? A: Real property taxes are due January 31, 2025. You may pay in full by January 31st, or split payments with first installment due January 31st and second due July 31st, 2025.

Q: What tax credits are available and do I need to apply? A: Wisconsin offers several tax credits that require annual application, including the Homestead Credit for qualified homeowners, Veterans Disability Credit, and Senior Citizen/Disabled Person Credit. These are credits that reduce your tax bill, not your assessed value, and applications must be filed with the Door County Assessor by specific deadlines.

Q: How does the Homestead Credit work? A: The Homestead Credit doesn't reduce your home's assessed value - instead, it limits how much your assessment can increase year-over-year and provides a credit against your tax bill. You must apply annually, and eligibility is based on income limits and residency requirements.

Q: How often is property reassessed in Door County? A: Door County assesses all real property annually as of January 1st. There is no assessment cap in Wisconsin, so your assessed value can increase to full market value each year.
