||How to File
Iowa does not have an extension form to obtain additional time to file an IA state tax return.
If at least 90% of your total tax liability is paid by May 1, 2018, you will automatically have until October 31, 2018 to file your return. You will not be charged a late file penalty. However, you may owe a penalty for failure to make estimated payments. You will owe interest on any tax still due after May 1, 2018. Iowa will not honor a federal tax extension as an extension to file an IA state tax return.
If you need to make a tax payment to meet the 90% requirement, you may arrange payment from your bank account through the Iowa Income Tax Payment application, pay by credit card online, or pay by telephone using the IA 1040V payment voucher form.

The state has more than 2,000 taxing authorities. Most property is taxed by more than one taxing authority.

State law requires all real property be assessed every two years in odd-numbered years.
Odd 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.
