Ted Benna is widely recognized as the father of the 401(k). He designed the structure in 1980 after identifying a section of the Internal Revenue Code that allowed for tax-deferred compensation. At the time, his employer, the Johnson Companies, sought a way to reduce tax burdens for workers. Benna realized that if employees contributed a portion of their salary to a profit-sharing plan, they would receive a tax break.
The initial rollout of this plan faced resistance from the Internal Revenue Service. Regulators argued that the language in the tax code did not permit individual employee contributions in the manner Benna proposed. He persisted, eventually gaining approval by aligning the plan with existing pension regulations. This pivot transformed how American retirement savings functioned by shifting the burden from employer-managed pensions to employee-funded investment accounts.
Over the decades, the 401(k) became the standard for retirement savings in the private sector. While Benna created the mechanism, he has frequently expressed concern regarding its current implementation. He points out that many participants do not save enough to support a full retirement. He also notes that the rise of high management fees and complex investment options often disadvantages the average worker.
Benna advocates for simplifying the system. He suggests that automatic enrollment and lower-cost index funds should be the default for all plans. His perspective remains grounded in the original intent of his discovery, which was to provide a straightforward tax advantage for the average earner. Today, the 401(k) holds trillions of dollars in assets, yet Benna continues to monitor the system he built to ensure it serves the people it was meant to assist.
