State of Indiana Business Income Tax Extensions

E-file an IRS business tax extension with TaxExtension.com

General Instructions

Indiana business tax returns are due by the 15th day of the 4th month after the end of the tax year — or April 15 for calendar year filers. If you cannot file by that date, you may request a state tax extension.

There are two ways to get an Indiana business tax extension:

1. If you have a valid 6-month Federal business extension (IRS Form 7004), you will automatically be granted an Indiana tax extension. In this case, you don’t need to file a separate state extension request. The deadline for your Indiana tax return will be moved to 30 days after the Federal extension deadline. (Note: The Federal extension deadline is September 15 for most businesses). A copy of your IRS-approved Form 7004 must be attached to your Indiana return when it’s filed.

2. If you don’t have a Federal tax extension, or if you need an extension beyond the 6-month automatic extension, you must submit a written request to the Indiana Tax Administration Division for a special extension of time to file. Make sure to do this before the filing deadline. Your request must explain why the extension is needed and for how long. The Tax Administration Division will then send you a notice of approval or rejection.

Note that a tax extension does not give you more time to pay Indiana tax. At least 90% of a business’ estimated tax liability must be paid by the original deadline of its return (April 15 for calendar year taxpayers). To make a state extension payment, use Form E-6 (Request for Indiana Corporate Estimated Quarterly Income Tax Return / Extension Payment). Your Indiana extension payment will be processed as a 5th estimated tax payment.

State tax payments can also be made online via Indiana’s Electronic Tax Payment Service: www.in.gov/dor/epay
