Form 1 (2023): Wisconsin Income Tax Return

The Wisconsin Income Tax Return (Form 1) is used by Wisconsin residents to report their taxable income for the previous year and calculate any taxes owed or due for a refund to the Wisconsin Department of Revenue (DOR).

Who Needs to File?

• Generally, anyone who owes Wisconsin income tax must file a return.
• Even if you don't owe any tax, you may still want to file to receive any refundable credits you qualify for.

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.
