<prompt> Human: Ive been contributing to a Roth IRA for the past few years, and I usually put in money between Jan-Apr after the tax year Im contributing for ex: put in 5500 in Feb 2016 for tax year 2015. Im over the income limit for my Roth now so Im planning on doing a backdoor conversion. If I open a traditional IRA now, put in 5500, wait a few days and then transfer it to my Roth, can that still count for tax year 2016? Or does putting the money into a traditional IRA somehow negate that?Thanks!  <response>: The deadline for executing a Roth IRA conversion for a given tax year is Dec. 31 of that year. This can cause some confusion, since you generally have until April 15 of the following year to add new money to a Roth or traditional IRA. But that only applies to new contributions, not to conversions.
