Required Minimum Distributions (RMDs)
You cannot keep retirement funds in your account indefinitely. You generally have to start taking withdrawals from your IRA, SIMPLE IRA, SEP IRA, or retirement plan account when you reach age 70½. Roth IRAs do not require withdrawals until after the death of the owner.
Your required minimum distribution is the minimum amount you must withdraw from your account each year.
You can withdraw more than the minimum required amount.Your withdrawals will be included in your taxable income except for any part that was taxed before (your basis) or that can be received tax-free (such as qualified distributions from designated Roth accounts).
Calculating the required minimum distribution
The required minimum distribution for any year is the account balance as of the end of the immediately preceding calendar year divided by a distribution period from the IRS’s “Uniform Lifetime Table.”
