Mandatory minimum distributions (RMD) must be made every year starting from the year you turn 72 and a half years old (70 and a half years old if you turn 70 and a half years old in 2013). Each year's RMD is calculated by dividing the IRA account balance as of December 31 of the previous year by the applicable distribution period or life expectancy. The IRS requires you to report this distribution in your annual taxes, so it must be done at the end of each calendar year. However, beyond that, you can structure this retirement based on your own financial interests.
Most retirees collect the required minimum distributions on an annual, quarterly, or monthly basis. As long as you withdraw the minimum required amount before December. Once you turn 72, you must withdraw the annual mandatory minimum distributions (RMDs) from your retirement accounts. You must calculate your RMD for each IRA separately, but you have the flexibility to deduct your full RMD amount from a single IRA or from a combination of IRAs.
People use IRAs to save for retirement throughout their careers, and it's easy to find information on how to invest their IRA to grow. If you have multiple IRAs, you must calculate each account individually, but you can deduct the total amount in RMD from an IRA or combination of IRAs.
