A few years ago we contributed to nondeductible IRAs and rolled them over into Roths, on the advice of our tax preparer at the time. I don't feel like getting into the question of whether that was a good idea or not, as it's done and our circumstances are different now so it doesn't make sense to consider doing it again. My question is this--I am reading now that when you contribute to a nondeductible IRA you are supposed to submit form 8606 to the IRS. We did not do this, unless our tax preparer or financial advisor did it for us, which I wouldn't think they would be able to. Do we need to go back and file this? I read that if you don't, it'll be treated like a deductible IRA and taxed thus at retirement. Or since the funds have since ended up in a Roth, does it matter?
