Worth noting that the limits are different between Roth IRAs and Traditional IRAs, though, if you have a retirement plan at work. A married couple making between 119k and 186k wouldn't get any deduction for the trad IRA, so might as well go with the Roth even if they think their income will be much lower in the future.

The Roth also lets you pull out contributions later without penalty, which is a nice worry-free safety net in case the emergency fund runs out.
