Per the IRS:
What is the deadline to recharacterize a Roth rollover or conversion?
You generally can recharacterize your rollover or conversion by October 15 of the following year, regardless of whether you requested an extension to file your tax return. For example, for your conversion to a Roth IRA in 2013, you have until October 15, 2014, to recharacterize. This deadline applies even if:
•you did not request an extension to file your 2013 tax return, and
•you file your return on or before April 15, 2014.
