Need More Time to File Your 2016 Iowa Income Tax Return? You Got it.
You have until May 1.
The 2016 Iowa individual income tax return is due on May 1, 2017, rather than the federal due date of April 18. Also, if you filed a federal extension, it does not apply for Iowa purposes.
No extension form needed.
If at least 90% of your total tax liability is paid by May 1, 2017, you will automatically have an additional six months to file your Iowa income tax return. You have until October 31, 2017, to file your return timely. You will not be charged a late file penalty, but you will owe interest on any tax still due after May 1.
To meet the 90% requirement by May 1, you may:
What if I can’t pay it all?
If you can’t pay your Iowa tax in full, file the return anyway and pay what you can by the due date. If you don’t file your return by the due date, and at least 90% of the correct tax is not paid, you will owe an additional 10% late penalty and interest on the unpaid tax. By filing the return on time, even if at least 90% of the correct tax due isn’t paid, you only owe an additional 5% late penalty, and interest on the unpaid tax.
Can I make more than one payment?
Yes, you can make additional payments until your return is processed. If you pay online through eFile & Pay select the option that says “final 2016 payment” to make additional payments. If paying by check or money order, send in the IA 1040V (pdf) payment voucher with each payment.
You will be billed for the balance due after your return is processed, including any penalty and / or interest that may apply. We encourage you to make payment prior to receiving a bill in order to reduce the interest amount due. Interest will accrue on the first of each month until the balance is paid.
NOTE: Once you receive a bill from the Department, you can set up a payment plan for the balance due. Details to set up a payment plan will be included with the bill.
