Hypothetical situation: Husband and wife retire at age 59.5 and their retirement assets are equally split between Roth IRAs and traditional IRAs. They will rely on these assets to generate 100% of their retirement income. Should they withdraw from the Roth first or the traditional first? Or split the withdrawals? I can make a case for all three.
If you take the withdrawal from the Roth IRA, you don't have to withdraw extra money to pay for taxes. That leaves more of your money invested. In addition, Roth distributions don't affect the tax on Social Security benefits.
If you take the withdrawal from the traditional IRA, you will be leaving more tax-free money for your heirs. You'll also be lowering your future RMD.
Finally, by splitting the withdrawals between the two IRA types, you'll stay more tax-diversified.
So what do you think, MIFP?
