Automatic Iowa Tax Extension
If you are certain that you cannot file your Iowa return by the deadline, you do not need to file for an extension. You will automatically receive a 6-month extension of time to file your return (not to pay). The extended tax return due date is October 31, 2020. Please be aware that Iowa will not accept the federal extension form as an extension for your Iowa tax return. However, if you expect to owe income taxes, you should submit your payment with payment voucher Form IA 1040V. If you efiled your return and are making a payment by check or money order, you must complete a Form IA 1040V on efile.com. If you are making a payment by credit card, a Form IA 1040V is not needed. If you are making an automatic extension payment, you also must use Form IA 1040V unless it is made electronically. Use efile.com and prepare an Iowa tax return to find out what your Iowa state income tax payment will be.
Important: Do you need to prepare and e-file an IRS or federal tax extension as well?

Iowa Tax Fact
In 2007, Iowa had a sales tax on pumpkins after officials decided that pumpkins were purchased solely as Halloween decorations (jack o' lanterns), not food (pumpkin pie). The IA governor eliminated the "pumpkin tax" after pumpkin farmers complained that the tax would decrease their profits. Though pumpkins are exempt from sales tax, inedible decorative gourds are taxed.
