The State of Wisconsin will automatically grant you a 6-month tax extension if you were approved for a federal tax extension. However, you will need to submit Wisconsin Form 1-ES (PDF) if you need to make a state tax payment.

If you do not need to make a tax payment and have received an approval notification from FileLater, there’s nothing more to do. When you file your state tax return, note on your Wisconsin personal income tax return that a federal extension was granted.

Filing for a Wisconsin tax extension will not provide you with additional time to pay any tax balance due, which must be paid by the original filing deadline, or interest and other payment penalties may apply.
