WI Tax Extensions
If you have an extension for filing your federal return, this automatically gives you a Wisconsin extension, provided you attach a copy of your federal extension application to your Wisconsin income tax return. If you would like to only obtain an extension for your WI state return, you must attach a statement to the state return indicating that you wish to use Federal Form 4868.
Even though you may have an extension of time to file your return, you will owe interest on any tax not paid by April 17, 2018. Therefore, when you file an extension, pay as much of your WI tax bill as you can. If you expect to pay additional taxes owed, you can avoid the 1% per month interest charge during the extension period by paying the tax you will owe by April 17, 2018. You can submit the payment with a 2017 Form 1-ES, Estimated Income Tax Voucher .

WI Personal Property Tax:
The real property tax (or residential property tax) is the most common personal property tax in Wisconsin. There is no property tax on vehicles, but the state does levy a registration fee.
Personal property taxes are the most important revenue source for local governments and school districts, as well as other special interest and finance divisions.
The state has two programs to help WI taxpayers with their personal property taxes:
- Homestead Credit: Available to homeowners and renters with lower incomes, the program allows them to decrease their property tax liability. They can either take an income tax credit or a direct tax refund to save money on their property taxes. The credit is based on the combination of the taxpayer s income and the allowable property taxes and/or rent for the Tax Year.
- Property Tax Deferral Loan Program: Available to qualifying elderly homeowners, this program provides them loans to help them pay their property taxes. It is operated by the Wisconsin Housing and Economic Development Authority (WHEDA).
Odd Tax Fact:
Take and bake pizzas are subject to Wisconsin sales tax because the state considers them prepared food.
