In addition, you can Roth and roll. You can roll your regular IRA into a Roth IRA if your income is below certain thresholds. You will need to pay tax on all the funds converted, but then neither future investment income nor withdrawals at retirement will be taxed. Moreover, there are no lifetime minimum distribution requirements for a Roth IRA, and contributions can continue to be made after age seventy and a half. Thus, significant amounts can be accumulated tax-free for the benefit of future generations.
