The 2020 Iowa State Income Tax Return for Tax Year 2020 can be e-filed together with the IRS Income Tax Return by April 15, 2021. If you file a tax extension you can e-File your Taxes until October 15, 2021 without a late filing penalty. However, if you owe Taxes and don't pay on time, you might face late tax payment penalties. Tip: File on time, even you can't pay on time, as the late filing penalties are higher than the late payment penalties.

eFile.com makes it easy for you to e-file your IRS and Iowa State Tax Return (e.g resident, nonresident, or part-year resident returns). However, the IRS and the respective State Tax Agencies require you to e-file a Federal Income Tax Return at the same time you e-file a State Tax Return. This is not an eFile.com policy but an IRS and State Agency policy. Thus, technically you cannot e-File anywhere - not just eFile.com - a Iowa Tax Return without also e-filing the associated IRS Tax Return. But there is good news, please read on.

Detailed instructions on how you can only prepare and mail in - not eFile - a Iowa 2020 Tax Return - here via eFile.com. However, you must download/print and sign the forms and mail them to the Tax Agency.

How to file an Iowa Tax Extension

For Tax Year 2020, if you do not owe taxes, you do not have to file a tax extension.  However, if you believe you will owe taxes and can't file on time, you should take action and here are the available options for Iowa:

  • If you do not owe Iowa income taxes by the tax deadline of April 30, 2021, you do not have to prepare and file a IA tax extension. In case you expect a IA tax refund, you will need to file or e-File your IA tax return in order to receive your tax refund money.
  • If you owe IA income taxes, you will need to pay at least 90% of your Iowa tax liability by April 30, 2021 to have an additional 6 months to file your return. The extension will only avoid late filing penalties until Oct. 31, 2021. Note: You may owe interest on any tax due after the April 30, 2021 deadline.  You have the follow options for IA tax payments:
    • Pay all or some of your Iowa income taxes online via: EasyPay Iowa or via ACI Payments. Pay your IA taxes online and you do not have to mail in Form IA 1040V.
    • Complete Form IA 1040V, include a Check or Money Order, and mail both to the address on Form IA 1040V.
    • Even if you filed an extension, you will still need to file your IA tax return either via eFile by Oct. 15, 2021 or Oct. 31, 2021 by paper.
  • Important: If you owe Iowa and/or IRS income taxes and do not file an IRS and Iowa tax return or extension by April 15, 2021, you will be subject to IRS and IA late filing penalties. Estimate IRS late filing, payment penalties. In addition, if you do not pay your taxes by April 15, 2021, you will be subject to late tax payment penalties. Filing an extension on time will ONLY eliminate the late filing penalties but not the late tax payment penalties. Late filing penalties are generally higher than late payment penalties, thus file something on time even if you can't pay anything on time!

Important: Do you need to prepare and e-file an IRS or federal tax extension as well?

The extended IRS/Iowa eFile deadline is Oct. 31, 2021 - eFileIT* Now. If you plan to file or mail-in a Iowa tax return on paper - the Forms and Mailing Address are below - your due date is Oct. 31, 2021.
