You saved for years to get to retirement—contributing to a traditional 401(k) or IRA. Now it’s time to dip into those savings—even if you don’t really need to. Because you got a tax break when you contributed to these accounts, once you turn age 70½ the IRS requires you to withdraw every year from your traditional IRA or employer-sponsored retirement plan account, such as a 401(k) or 403(b), and start paying taxes on that money.1 It’s important to determine how these minimum required distributions—known as MRDs or RMDs (required minimum distributions)—fit into your retirement income plan.
