What Is A Roth Conversion, And How Do I Set One Up? (Ad) A Roth conversion moves money from a traditional IRA or employer plan into a Roth IRA, triggering income tax that year in exchange for potential tax-free qualified growth later. Key questions remain: how much to convert, where the tax payment comes from, and whether this years income leaves room. Roth IRAs also avoid lifetime required minimum distributions. A fiduciary financial advisor can help size a conversion around your specific tax situation and goals. Get matched with a vetted fiduciary advisor in your area today
