What is the statute of limitation in Indiana for income tax liability?

The statute of limitations for taxes in Indiana is 3 years after the tax was due or after the return was filed, whichever is later. So for instance if you have a tax return due April 15, 2005 and the return is filed February 1, 2005 the statue of limitations is April 15, 2008. If the return was filed on June 15, 2005 with the same due date, the statue of limitations would run out on June 15, 2008.
