<prompt> Human: Hi all,I just opened up a roth ira, and I know that I can fund for 2017 up until the tax deadline in 2018, but I was wondering if that means I can use money earned in February 2018, for example, to fund my roth ira for 2017. I hope this makes sense.Thanks in advance!  <response>: Yes, you can.There is an additional restriction that might apply to you: You can only fund your Roth IRA up to the amount that you earned in that fiscal year. E.g. if you had 5000 earned income in 2017, the most you can put into your 2017 Roth IRA is 5000. If you earned at least 5500 in 2017, then this limit doesnt apply to you.
