What Is Wisconsin Form 1?

Wisconsin Form 1 is the individual income tax return used by full-year Wisconsin residents to file their state income tax return. The purpose of Form 1 is to calculate how much income tax you owe the state of Wisconsin, or how much refund you may receive. Part-year residents and nonresidents generally use Wisconsin Form 1NPR instead.

Complete your federal income tax return first because Wisconsin Form 1 uses income, deductions, and other information from your federal return. Read the Wisconsin Department of Revenue Which Form to File guidance to help determine whether you should use Form 1 or Form 1NPR for tax year 2025.

Who Must File Wisconsin Form 1?

You must file a Wisconsin tax return if your gross income exceeds the minimum specified for your filing status. For tax year 2025, Single full-year residents under the age of 65 generally must file if their gross income is $14,260 or more. Married Filing Joint full-year residents with both spouses under the age of 65 generally must file if their gross income is $26,510 or more.

Gross income means all income before deducting expenses that is reportable to the state of Wisconsin. It does not include income that is exempt from Wisconsin tax, such as Social Security benefits or U.S. government interest. Even if your gross income is below the amount specified for your filing status, you may still need to file a Wisconsin tax return.

Frequently Asked Questions (FAQ)

Here are answers to common questions about printing, mailing, documenting, and filing Wisconsin Form 1. These FAQ focus on practical details from the official form and instructions.

When is Wisconsin Form 1 due?

For tax year 2025, Wisconsin Form 1 is generally due April 15, 2026. If you need more time to file, review the extension rules in the Wisconsin Form 1 instructions booklet. Wisconsin generally allows federal extension provisions, but you must pay any Wisconsin income tax due by the original deadline to avoid interest and possible penalties.

Should I use a pencil or pen on Wisconsin Form 1?

Use black ink if you print and complete Wisconsin Form 1 by hand. Do not use pencil or red ink. Clearly write your name and address using capital letters, round amounts to whole dollars, and do not staple your return. See the Paper filing and Assembling your return sections of the instructions booklet for related information.

Do I include Forms W-2 and 1099 with Wisconsin Form 1?

Yes. Include readable copies of the appropriate withholding statements listed in the Wisconsin instructions, such as Forms W-2, W-2G, 1099-G, 1099-R, 1099-MISC, and 1099-NEC. Only include withholding statements for the tax year you are filing. If you are reporting Wisconsin income tax withheld, make sure the statement shows the Wisconsin withholding amount. Read the Assembling your return section of the Wisconsin Form 1 instructions booklet before mailing your return.

Do I include my federal return with Wisconsin Form 1?

Yes. The Wisconsin Form 1 instructions say to include a complete copy of your federal income tax return, Form 1040 or Form 1040-SR, with its supporting schedules and forms. Complete your federal return first because Wisconsin Form 1 uses information from your federal return. If you are not required to file a federal return, list the sources and amounts of your income and deductions on a separate sheet of paper and include it with Form 1.

Can I amend a Wisconsin Form 1?

Yes. If your original return was filed on Wisconsin Form 1, file an amended Wisconsin Form 1 and check the amended return space at the top of page 1. Include Schedule AR, Explanation of Amended Return, and the supporting forms and schedules for the items changed. Do not send a copy of your original return.

How long should I keep my Wisconsin tax records?

Keep copies of your Wisconsin tax returns indefinitely. Wisconsin generally says to keep supporting tax records until the period of limitations runs out, usually four years from the due date of the return or the date filed, whichever is later. Keep records longer for certain situations, such as underreported income, property basis, net operating losses, false or fraudulent returns, or years when no return was filed.
