<prompt> Human: Good people of rpersonalfinance,I have something of a dilemma. I switched jobs this year from a standard corporate job with 401k to a start-up job without a 401k at this point. Aside from rolling over my 401k easy and painless - thank you Vanguard, I also opened a Roth IRA account. This was early in the year, so I was able to fund the Roth IRA with 11,000, the full 5,500 for each of tax years 2015 and 2016. However, in planning my 2017 retirement savings strategy, I realized Im going to exceed the Roth IRA income limits for 2016 a happy problem to have, of course. Shame on me for not noticing before of course, but alas whats done is done. Questions for rpersonalfinance: I assume the backdoor Roth IRA is the answer and I know there have been excellent how-to guides posted here before, but can one do a retroactive backdoor Roth? If so, should I wait to do so after January 1, when I prepared to put another 5,500 in for tax year 2017? Market performance since I initially invested has turned the 11,000 into just over 12,000. Am I at risk of forfeiting half of those gains? frowny face emoji My understanding is that a backdoor Roth is technically a tax loophole. Since Vanguards customer service has been so great, my first instinct is to call them and explain and get their assistance. Is doing a backdoor Roth something thats frowned upon in this establishment to a brokerage? This subreddit is full of very knowledgeable and helpful folks with terrific advice. Thanks in advance. TL;DR: Already put in full limit of Roth IRA funding for 2016, realized later I will exceed the income limits for 2016. Pop quiz hotshot, what do I do?  <response>: The year isnt over until its over, and IRA years are extra-long.It doesnt matter what youve done so far, you can undo everything, and do something else.
