Illinois
State of Illinois Personal Income Tax Extensions – Tax Year 2009
 GENERAL INSTRUCTIONS
The State of Illinois will automatically grant you a 6-month tax extension without having to file any paperwork. However, you need to submit Illinois Form IL-505-I (PDF) if you owe the state money for income taxes.

If you do not need to make a state tax payment and have received an acceptance notification from FileLater, there’s nothing more to do.

Filing for an Illinois tax extension will not provide you with additional time to pay any tax balance due, which must be paid by April 15 or interest and other payment penalties may apply.

For additional information, please visit the State of Illinois Department of Revenue website.
