<prompt> Human: I know Roth IRAs have a max contribution of 5,000, so I would assume opening 2 would be best, but Im not sure if maybe the max amount increases if two people are on the same account. Ive had my own account for about a year.  <response>: You should have two separate so you can both contribute 5,500 each to your IRAs. The maximum for a single IRA is 5,500 regardless of your marital status, so the only way to contribute 11,000 a year is to have two.Source:
