Your Wisconsin Income Tax Return

Efile.com makes it easy for you to e-file your state tax return (e.g resident, nonresident, or part-year resident returns). However, the IRS and the respective state tax agencies require you to e-file a federal income tax return at the same time you efile a state tax return. This is not an efile.com policy but an IRS and state agency policy. Many taxpayers have asked how they can only prepare and file a state income tax return. The efile.com tax application lets you prepare a state tax return only, however you cannot efile the state return upon completion. Instead, you will have to download the completed state tax return as a PDF file, print it, sign it, and mail it to the respective state - the address is on the PDF file. Find more detailed instructions on how to prepare and file a state only return on efile.com.

How To File a Wisconsin Tax Extension

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 15, 2019. 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 15, 2019. You can submit the payment with a 2018 Form 1-ES, Estimated Income Tax Voucher.

Important: Do you need to prepare and e-file an IRS or federal tax extension as well?

How to File a Wisconsin Tax Amendment

Amended Wisconsin tax returns can only be mailed; they cannot be efiled. Learn how to file a Wisconsin tax amendment.

Important Reminder! If you are filing a Wisconsin tax amendment, you may need to file a federal tax amendment as well.

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 Wisconsin Tax Fact

Take and bake pizzas are subject to Wisconsin sales tax because the state considers them prepared food.
