When Are State Tax Returns Due in Iowa?
Iowa is one of several states in which your state income tax return can be filed after April 15.
You probably already know that most Americans have to file their 2018 federal tax return by April 15, 2019 (as we told you earlier). For most states with an income tax (there are nine states with no income tax), the state return is also due on April 15 this year. However, some states give you more time to file — such as Iowa.
States With Tax Deadlines After April 15 in 2019
|New Mexico||April 30 (if e-filed)|
|Oklahoma||April 22 (if e-filed)|
Iowa gives its residents until April 30, 2019, to file their 2018 Form IA 1040.
If you're not quite ready to file by the deadline, Iowa automatically gives you six more months to file Form IA 1040 if you pay at least 90% of your total state tax liability by April 30. If you pay on time, you won't be charged a late-filing penalty.
We recommend filing both federal and state returns at the same time if possible. State returns typically "piggyback" off the federal return, so it's usually easier to do them at the same time. There's also a better chance of avoiding discrepancies if you do them together. However, if that's not possible, having an extra two weeks to file your Iowa return can help. It gives you more time to focus on getting your federal return off before the April 15 deadline and then to get your state return just right.
