A small tax-code clause changed who built a retirement fund
Before the 401(k) caught on, many workplace pensions promised a set benefit, often based on salary and years of service. The new arrangement worked differently: an employer could let workers direct some pay into a retirement account, where it could be invested rather than paid out as take-home wages. Benefits consultant Ted Benna recognized that section 401(k), originally part of a broader tax law, could support this kind of workplace savings plan.
The crucial feature was tax deferral. In a traditional 401(k), eligible contributions generally come out of pay before federal income tax is calculated. That lowers taxable income today; taxes are generally due when the money is withdrawn in retirement. The account can grow through investment returns, but those returns are not guaranteed—and the worker bears the risk that savings and investments may fall short.
Why employers and workers both had a role
The arrangement gave employers a way to offer retirement savings without promising a particular pension payout for life. They could contribute too, sometimes matching part of what employees saved. A match made saving more rewarding, but it also tied the size of an employee’s eventual fund partly to whether they contributed and how their investments performed.
That shifted more responsibility toward individual workers: deciding how much to save, choosing among available investments, and living with the results. It also made workplace retirement plans easier to adapt across different employers than a traditional pension tied to a single employer’s benefit formula.
From provision to everyday name
The section was not written as a consumer brand. Its number became the shorthand for a plan built around the tax treatment it allowed. As employers adopted the approach, the legal clause became a familiar part of workers’ financial lives—often encountered as a line on a pay stub or an account balance, rather than as a provision of tax law.
The lasting change was more than a new account label: retirement saving increasingly depended on choices made paycheck by paycheck, with the tax code shaping the incentives behind them.
