General Instructions

Iowa has extended the individual income tax filing deadline to June 1st.

Iowa personal income tax returns are due by April 30. If you cannot file by that date, you can get a state tax extension.

An Iowa personal extension is automatic, which means there are is no application to submit. However, at least 90% of your Iowa tax liability must be paid by the original deadline (April 30) to avoid penalties. As long as you meet that requirement, you will automatically receive a 6-month Iowa tax extension, which moves your filing deadline to the last day of October.

If you owe tax, you can make a state tax payment using Iowa Form IA 1040V (Individual Income Tax Payment Voucher). Tax payments can also be made online through Iowa’s “eFile & Pay” system:
