Iowa State Tax Filing Deadlines 2023

The State of Iowa government has issued the following guidance concerning income tax filing deadlines and extensions:

• The tax filing due date for 2022 Iowa income tax returns is May 1, 2023.
• Qualifying taxpayers who file and pay by this date will not be subject to late-filing or underpayment penalties. Interest on unpaid taxes, however, will accrue starting May 1st, 2023.
• Iowa residents are not required to file for a personal extension as it is automatic. To avoid penalties, it is advised that at least 90% of the individual’s Iowa tax liability is paid by May 1st, 2023. By fulfilling this requirement, the individual’s filing deadline will be extended to October 31st, 2023.
