Indiana Filing Due Date: Business tax returns are due by April 15 — or by the 15th day of the 4th month following the end of the taxable year (for fiscal year filers).
Extended Deadline with Indiana Tax Extension: Indiana offers an automatic 6-month extension to businesses that have a valid Federal extension (IRS Form 7004), which moves the filing deadline to October 15 (i.e. 30 days beyond the Federally extended deadline).
Indiana Tax Extension Form: To apply for an extension, you must send a written request to the Indiana Tax Administration Division by the original deadline of your return. Your statement must include your reason for requesting the extension as well as how much extra time you need to file. You will then receive a notice saying whether your extension request has been approved or denied. Send your extension request to the following address:
Indiana Department of Revenue
Data Control Business Tax
Returns Processing Center
100 N. Senate Avenue
Indianapolis, IN 46204-2253
Indiana Extension Payment Requirement: An extension of time to file is not an extension of time to pay. To avoid interest and penalties, your Indiana tax liability must be paid by the original due date. A tax extension will prevent you from incurring the late payment penalty during the extension period, as long as 90% of your Indiana tax is paid on time. You can make an Indiana extension payment with Form E-6, or you can pay online using Indiana’s Electronic Tax Payment Service: www.in.gov/dor/epay
Indiana Tax Extension Tip: If you have an approved Federal extension (IRS Form 7004), you will automatically receive an Indiana extension. In this case, your Indiana tax return will be due within 30 days after the extended deadline for your Federal return.
