If you have neglected retirement planning most of your life, you may have one last chance starting at age 69 that could determine how you live your final years and if you leave anything to heirs, some financial advisers said.

Age 69 begins the last stretch before required minimum distributions (RMDs) start at age 73 and is still early enough to take steps to keep taxes low, advisers said. For example, Americans may find the road from 69 to 73 is the best time for Roth conversions, advisers said. Withdrawals from Roth accounts are tax- and penalty-free as long as your’re 59-1/2 years or older and your first contribution was made at at least five years ago.
