The deadline for 2015 returns is April 18, 2016.

The IRS recently updated Publication 509 (http://www.irs.gov/pub/irs-pdf/p509.pdf) which lists all the filing due dates for 2014.

If you need to file a Form 1065 (partnership return), Form 1120S (S corporation return) or Form 1041 (fiduciary return) the deadline to file your 2012 return is September 16, 2013. This assumes you had filed for an extension prior to April 15, 2013.

If you haven’t filed your tax return by now, you should probably consider filing for an extension. It is a lot easier to file for an extension than it is to amend a return later for a mistake you made trying to rush your return to completion. Even more costly is if the IRS finds a mistake you made and assesses underpayment penalties and interest.

Refunds totaling more than $1.1 billion may be waiting for nearly 1.1 million people who did not file a federal income tax return for 2007, the Internal Revenue Service announced recently. However, to collect the money, a return for 2007 must be filed with the IRS no later than Monday, April 18, 2011. For Ohio, the IRS estimates there are 33,200 unfiled returns with an average refund of $620.
