<prompt> Human: Basically I make 100K and bonus can be any amount from 0 - 30K. I dont currently have an IRA but would like to open one. I have a 401K and am contributing up to the match, my emergency fund is almost where it should be. Any advice on how I should proceed?  <response>: You have until tax day of the following year to retroactively make contributions to a Roth IRA for the preceding year.i.e. You can make Roth IRA contributions for the 2013 tax year all the way up until April 15, 2014 or when you file your 2013 tax return, whichever comes first.In your case, since your eligibility hinges on the size of your bonus, I would set aside the 5,500 throughout the year as savings and put all or part of that in a Roth IRA in January 2014 if you find that your total salary makes you at least partially eligible to contribute. Worst case scenario, you have some extra savings that can be put in a taxable investment account :
