Required Minimum Distributions (RMDs) generally are minimum amounts that a retirement plan account owner must withdraw annually starting with the year that he or she reaches 70 ½ years of age or, if later, the year in which he or she retires. However, if the retirement plan account is an IRA or the account owner is a 5% owner of the business sponsoring the retirement plan, the RMDs must begin once the account holder is age 70 ½, regardless of whether he or she is retired.
Retirement plan participants and IRA owners are responsible for taking the correct amount of RMDs on time every year from their accounts, and they face stiff penalties for failure to take RMDs.
The RMD rules apply to all employer sponsored retirement plans, including profit-sharing plans, 401(k) plans, 403(b) plans, and 457(b) plans. The RMD rules also apply to traditional IRAs and IRA-based plans such as SEPs, SARSEPs, and SIMPLE IRAs.
The RMD rules also apply to Roth 401(k) accounts. However, the RMD rules do not apply to Roth IRAs while the owner is alive.
When a retirement plan account owner or IRA owner dies before RMDs have begun, different RMD rules apply to the beneficiary of the account or IRA. Generally, the entire amount of the owner’s benefit must be distributed to the beneficiary who is an individual either (1) within 5 years of the owner’s death, or (2) over the life of the beneficiary starting no later than one year following the owner’s death.
Generally, a RMD is calculated for each account by dividing the prior December 31st balance of that IRA or retirement plan account by a life expectancy factor that IRS publishes in Tables in Publication 590, Individual Retirement Arrangements (IRAs).
