The State of Iowa will automatically grant you a 6 month business income tax extension. However, if you need to make a state tax payment, you will need to submit Iowa tax payment voucher Form IA 1120V (PDF).

If you do not need to make a tax payment and have received an approval notification from FileLater, there’s nothing more to do.

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

For additional information, please visit the State of Iowa Department of Revenue website.

Make a payment online by using Iowa "eFile and Pay" (this link will take you to a site not managed by FileLater)
