General Instructions
Choose your state from the list below to access detailed instructions for both business and personal tax extensions.
Individual income tax returns are due by April 30 — or by the last day of the 4th month following the end of the taxable year (for fiscal year filers).
Iowa offers a 6-month extension, which moves the filing deadline to October 31 (for calendar year filers).
Iowa’s tax extensions are automatic, so there is no official application or written request to submit. You will automatically be granted an Iowa extension as long as you meet the state’s payment requirement (see below).
An extension of time to file is not an extension of time to pay your Iowa income tax. All state tax payments are due by the original deadline of the return. Any Iowa tax that isn’t paid by the proper deadline will be subject to interest and penalties. In order to receive an automatic Iowa extension, at least 90% of your total state tax liability must be paid on time. You can make an Iowa extension payment with Form IA 1040V, or pay electronically using Iowa’s eFile & Pay system: tax.iowa.gov/efile-pay
