<prompt> Human: Started contributing to a Roth IRA at the beginning of this month. Do I have until April 15th, 2018 as my deadline for my 2017 contributions? If I reach the 5,500 limit for 2017 before this deadline, can I start contributing early towards 2018?  <response>: You can contribute to either your 2017 or 2018 roth between Jan 1 and April 15. Before that you can only contribute to 2017. After that you can only contribute to 2018.
