Iowa State income tax filing deadlines 2024
The State of Iowa government has issued the following guidance concerning income tax filing deadlines and extensions:
- The state tax filing due date for 2023 Iowa income tax returns is April 30, 2024.
- 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 1, 2024.
- 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 April 30, 2024. By fulfilling this requirement, the individual’s tax filing deadline will be extended to Oct. 31, 2024.
