Start converting some money now from a traditional IRA to a Roth. The money can grow tax-free in the Roth, and you're not required to take minimum distributions from it. Thinkstock By Kimberly Lankford, Contributing Editor From Kiplinger's Personal Finance, May 2015 I turned 65 this year. I am retired and living on my pension. I will have to take required minimum distributions from my IRA when I turn 70 1/2. How should I reinvest the RMDs from my IRA to reduce the taxes on them in the future? --J.H., via e-mailSee Also: SLIDE SHOW: 6 Savvy Moves to Stretch Your Retirement Savings Rather than searching for low-tax investments once the money is out of the IRA, start converting some money now from the traditional IRA to a Roth. You'll have to pay taxes on the conversion, but the money can grow tax-free in the Roth, and you're not required to take minimum distributions from it. When deciding how much to convert, be aware of the income thresholds for the Medicare Part B and Part D surcharge, which boosts premiums if your income tops $85,000 (for singles) or $170,000 (for joint filers). A large conversion in one year could also bump some money into the next tax bracket or cause more of your Social Security benefits to be taxed (see Are Your Social Security Benefits Taxable?).
