Retirement

Dear Liz: I began converting two 401(k)s from previous employers to Roth IRAs. To lessen the huge tax hit, I decided to do the conversions over the course of seven years. Even with that, the tax hit is higher than I realized and too painful. Now that partial conversions have begun annually, am I required to complete the total conversion to 100%? Or can I stop midway and leave the remainder in the original accounts? Also, is there an age limit before which Roth conversions must be completed?

Answer: You don’t have to continue making conversions. (Before 2018, you could have even reversed conversions you already made, but that’s no longer possible.) There’s also no age limit for conversions, but the older you get, the less likely conversions are to make financial sense.

Conversions are a good bet if you expect to be in the same or a higher tax bracket in retirement. If you’re young and in a low tax bracket now, you can reasonably expect that to be the case.

As you approach retirement, though, the opposite may be true. Many people find their tax bracket drops once they retire. Why pay a big tax bill now if you can access the money at a lower tax rate later?

Then again, if you’re a good saver, you may discover you’ve accumulated so much that your tax bill will soar once you’re required to start taking minimum distributions at age 72. If that’s the case, then converting some of your retirement money might save you on taxes overall.

But you’ll want to discuss this with a tax pro or financial planner who can model how the conversions are likely to affect your overall finances, including any Medicare premiums, since those can increase with income.
