INSTRUCTIONS: WISCONSIN INCOME TAX (Form 1)

Wisconsin residents use a form 1 to file their state income tax if they cannot use the short-form 1A form. Reasons for this include income which cannot be documented on a form 1A, such as that derived from a farm or business or adjustments such as alimony payments and tuition expenses. Both documents, as well as an instruction booklet for both, are found on the website of the Wisconsin Department of Revenue.
