Ted Benna built 401(k) plans for ordinary workers from a tax-code loophole

The Revenue Act of 1978 added a short, technical paragraph to the tax code, Section 401(k), meant to settle a narrow dispute over executive profit-sharing plans — companies had been letting senior employees defer bonuses into tax-advantaged accounts, and Congress wanted clear rules for exactly that practice. Nothing about the provision was written or debated as a retirement-savings tool for the broader workforce; ordinary employees at the time typically had, at best, a traditional employer-funded pension and no way to set aside their own pretax salary.

Ted Benna, an employee-benefits consultant, was reading the same paragraph everyone else in the pension business had already read and filed away as an executive-bonus technicality. The statute set out conditions for deferring compensation into a tax-advantaged plan, but it didn't specify that only bonuses qualified, or that only executives could participate — a silence nobody else in the industry had treated as an opening.

Read the statute's silence as permission, built a plan deferring ordinary paychecks, and let regulators bless the working example rather than ask first.

The statute didn't limit who could defer pay, so Benna's literal reading covered all employees.

He implemented the plan with real paychecks, giving regulators a working example to bless.

Treasury had no reason to reject a plan that was already working and caused no harm.

His early adoption made him the popularizer, spreading the idea across the industry.

When a rule is written for one purpose but doesn't forbid a broader use, test the silence by building a real example, then seek confirmation.

The U.S. Treasury did not strike the interpretation down: in 1981 it proposed regulations that effectively validated salary-reduction 401(k) plans for rank-and-file employees, formally blessing the reading Benna had already built a real plan around. Other firms — among them FMC, PepsiCo, JC Penney, Honeywell and Hughes Aircraft — began developing their own 401(k) proposals within the same few years, and Benna became known industry-wide as the plan's popularizer and first real-world implementer.
