Required minimum distributions

An account owner must begin making distributions from their accounts at least no later than the year after the year the account owner turns 70½ unless the account owner is still employed at the company sponsoring the 401(k) plan. The amount of distributions is based on life expectancy according to the relevant factors from the appropriate IRS tables. The only exception to minimum distribution are for people still working once they reach that age, and the exception only applies to the current plan they are participating in. Required minimum distributions apply to both pre-tax and after-tax Roth contributions. Only a Roth IRA is not subject to minimum distribution rules. Other than the exception for continuing to work after age 70½ differs from the rules for IRA minimum distributions. The same penalty applies to the failure to make the minimum distribution. The penalty is 50% of the amount that should have been distributed, one of the most severe penalties the IRS applies.
