“In the United States, a 401(k) plan is an employer-sponsored, defined-contribution, personal pension (savings) account, as defined in subsection 401(k) of the U.S. Internal Revenue Code. Periodical employee contributions come directly out of their paychecks, and may be matched by the employer. This legal option is what makes 401(k) plans / contracts attractive to employees, and many employers offer this option to their (full-time) workers.”
