Roth IRA Conversion

See: Roth IRA.

A popular thing to do, especially among those moving from high-tax Blue States to low-tax Red States. They'll simply convert their normal IRA into a Roth IRA by paying the gains taxes on that old traditional IRA (ordinary income tax rates when they close it out), and then roll that net saved dollar into a Roth IRA, so that they can just appreciate taxlessly into the future.

Do the math. It may make a ton of sense.
