401(k) Retirement Account

A type of retirement plan in which people who are employed can automatically have money taken out of their paychecks and put aside into an account that is taxed less than a standard savings or investment account. This helps the account grow more quickly than other accounts. The person who puts the money aside can only use this money after reaching the age of 59 and a half. If money is withdrawn before that age, the person taking the money out has to pay a penalty.
