Are distribution rules for 401(k) and 403(b) plans the same as those for IRA plans?

The distribution rules are the same for 401(k), 403(b) and traditional IRA plans, SEP IRAs and SIMPLE IRAs, according to the IRS. However, Roth IRAs do not follow the same rules for a Required Minimum Distribution and do not have to be withdrawn from until after the owner dies.

The Required Minimum Distribution rule states that account holders and beneficiaries must withdraw a minimum amount of money from certain tax-deferred savings plans based on the life expectancy factor defined by the IRS and the previous year's plan balance, as explained by the IRS. Other plans that follow this rule include 457(b) plans, certain profit-sharing plans and some defined contribution plans.
