How do I change the tax year reported for a traditional IRA contribution in my reported taxes?
I made a contribution to my traditional IRA in January 2017 before the April 2017 tax filing due date, so I reported the contribution as tax year 2016. My bank, however, applied the contribution to 2017 tax year. I was informed by them that I missed the October 15, 2017 deadline for changing the tax year applied to that contribution to 2016. Do I need to re-file tax year 2016 to remove the traditional IRA contribution and include the contribution in my 2017 taxes? If so, how do I go about re-filing for 2016?
