Form 1: Wisconsin Income Tax Return

Form 1, also known as the Wisconsin Income Tax Return, is the official document used by Wisconsin residents to report their taxable income and calculate any taxes owed (or refunds due) to the state of Wisconsin.

Who Needs to File Form 1?

A. Residents: Anyone who resided in Wisconsin for the entire tax year must file a Form 1, regardless of income level.

B. Part-Year Residents: If you lived in Wisconsin for part of the year, you may need to file Form 1NPR (Nonresident and Part-Year Resident Return).

C. Non-Residents: In some cases, non-residents who earned income in Wisconsin may need to file Form 1.

What Information Do I Need to File Form 1?

Here's what you'll typically need to gather before filing your Form 1:

A. Federal Tax Return: A copy of your federal tax return (usually Form 1040) is often used as a starting point.

B. Income Documents: W-2s, 1099s, and other documents showing your income from wages, interest, dividends, etc.

C. Deductions and Credits: Documentation for any deductions or credits you plan to claim (e.g., medical expenses, charitable contributions).

D. Social Security Numbers: Social Security numbers are required for yourself and any dependents you claim.

E. Banking Information: For direct deposit of your refund (if applicable).

Key Points to Remember:

Filing Electronically: Wisconsin encourages e-filing your return. This is generally faster and more secure than mailing a paper return. You can also download the Form 1 attached below.

Deadlines: The deadline to file your Wisconsin income tax return typically coincides with the federal filing deadline (usually April 15th). However, extensions may be available. Check the Wisconsin Department of Revenue website for the latest information.

Payments: If you owe taxes, be sure to include your payment with your return.
