Dear Liz: I’m considering converting an old 401(k) to a Roth IRA. Will the gains from the 401(k) account be treated as capital gains? And can you only convert 401(k) plans you no longer participate in, or can you convert both current and former 401(k) plans?
Answer: You’ll pay income taxes on the conversion. Retirement plans, including 401(k)s and IRAs, don’t qualify for capital gains tax rates. You may be able to convert your current 401(k) as well. Ask your plan administrator if “in plan Roth conversions” are allowed.
