How Property Tax Works

Manitowoc County, Wisconsin operates on a property tax system that serves as the primary funding mechanism for local government services, schools, and various municipal functions. Property taxes in the county are assessed based on the fair market value of real estate as of January 1st each year, with an assessment ratio of 0.686 applied to determine taxable value. The Wisconsin base rate averages around 1%, though Manitowoc County's effective rates can vary significantly depending on your specific location within the county.

Tax bills are created and mailed by the third Monday in December each year, with payment due by January 31st of the following year. The actual tax rate you pay depends on your property's location within various special taxing districts, including school districts, municipal boundaries, and special assessment districts. This means two properties of equal value in different parts of Manitowoc County may have different total tax obligations based on the services and districts that serve each area.

Section 4

Supplemental Tax Bills

Supplemental taxes in Manitowoc County are typically triggered by changes in property ownership, new construction, or significant improvements that increase a property's assessed value during the tax year. When these changes occur after the January 1st assessment date but before the tax year ends, a supplemental tax bill may be issued to capture the additional tax liability for the remainder of the tax year.

The supplemental tax is calculated by determining the difference between the new assessed value and the original assessed value, then applying the current tax rate to that difference, prorated for the remaining months in the tax year. For example, if you complete a $100,000 home addition in June and your total tax rate is $20.00 per $1,000 of assessed value, you would owe approximately $1,333 in supplemental taxes (($100,000 ÷ 1,000) × $20.00 × 8/12 months remaining). Supplemental tax bills are issued separately from regular tax bills and have their own payment due dates.

Escrow & Property Taxes

Most mortgage lenders in Manitowoc County require property tax escrow accounts for loans with less than 20% down payment. Your lender collects monthly escrow payments along with your mortgage payment, then pays your property taxes directly to the Manitowoc County Treasurer when they become due on January 31st. Lenders typically collect 1/12th of your estimated annual tax bill each month, plus a cushion of up to two months' worth of payments as required by federal law.

Each year, your lender will conduct an escrow analysis to ensure adequate funds are being collected. If your property taxes increase due to rising assessments or tax rate changes, your monthly escrow payment will be adjusted accordingly. You should receive an annual escrow statement showing all deposits, payments, and any surplus or shortage. Property owners remain ultimately responsible for ensuring taxes are paid on time, even when using escrow, so it's important to verify that payments are made correctly and promptly contact your lender if you notice any issues with tax payments.
