What is the deadline for filing my state income tax return?

The deadline for filing your state income tax return in Indiana is generally April 15th. However, if April 15th falls on a weekend or a legal holiday, the deadline is extended to the next business day. It is important to note that requesting an extension to file does not grant an extension for paying any taxes owed. If you are unable to file by the deadline, you must submit a Request for Extension of Time to File form by the original due date to avoid penalties. Remember to file your return electronically if you are able to, as it is the quickest and most efficient way to receive a refund.
