Indiana Filing Due Date: Individual income tax returns are due by April 15, in most years — or by the 15^th day of the 4^th month following the end of the taxable year (for fiscal year filers).

Extended Deadline with Indiana Tax Extension: Indiana offers a 7-month extension to individuals, which moves the filing deadline to November 15 (for calendar year filers).

If you have a Federal tax extension (IRS Form 4868), you will automatically receive an Indiana tax extension for the same amount of time (6 months) plus 30 additional days to file your Indiana return. In this case, the Indiana filing deadline is extended to November 15 (for calendar year filers).

Indiana Tax Extension Form: To request an Indiana-only extension, file Form IT-9 by the original due date of your return.

Indiana Extension Payment Requirement: An extension of time to file is not an extension of time to pay your Indiana income tax. All state tax payments are due by the original deadline of the return. Any Indiana tax not paid by the proper due date will be subject to interest and penalties. In order to be granted an Indiana extension, at least 90% of your state tax liability must be paid on time. You can include your Indiana extension payment with Form IT-9, or pay electronically using Indiana’s ePay system: www.in.gov/dor/ePay

Indiana Tax Extension Tip: If you are requesting an Indiana-only extension and you owe zero state tax, make sure to complete Part 2 (Nonpayment Information) of Form IT-9.
