Decision: Don E. Williams Co. v. Comm’r, 429 U.S. 569 (1977).

Don E. Williams Co. v. Commissioner concerned year-end deductions claimed after a closely held corporation delivered interest-bearing, fully secured demand notes to the trustees of its qualified employee profit-sharing plan and later paid the notes by check.

The employer accrued a contribution and delivered its own notes

For fiscal years ending April 30 in 1967, 1968 and 1969, the corporation accrued contributions of about $30,000 and delivered its notes in May. The 1967 and 1968 notes bore 6% interest and the 1969 note 8%. Officers guaranteed them and pledged substantial collateral, but those protections did not constitute an actual outlay by the corporation. Don E. Williams, 429 U.S. at 571–572. The notes were paid by check within the following year.

Section 404 required an amount actually paid

The Court read the statutory terms paid and payment, the grace period, and legislative history to require cash or its equivalent by the applicable deadline regardless of the employer’s accrual method.

The maker’s note remained only a promise

Although a valuable note can be income to a recipient in other settings, the corporation’s own note did not itself transfer cash or other property out of the corporation. Full security and demand terms did not turn the promise into payment. The Court also refused to reconstruct the arrangement as cash contributed to the trust and then lent back: Those were not the transactions that occurred. A check later honored differed because it directed the bank to make payment; the maker’s note only promised payment. Don E. Williams, 429 U.S. at 579–580, 582–583.

The claimed earlier-year deductions were denied

The Court affirmed the disallowance of deductions for the years in which the notes were delivered; deductions followed the later checks. Current qualified-plan contributions must satisfy the present Code, plan terms, funding rules, and tax-year deadlines.

Justice Stewart, joined by Justice Powell, dissented. He agreed that a bookkeeping accrual was insufficient but would have treated these secured demand notes as payment by an accrual-method employer. He focused on what the trust received: Negotiable, interest-bearing notes that it could turn into full face value at a bank. He considered that value sufficient to protect the plan and read the earlier cash-payment cases as involving cash-method taxpayers. Justice Stevens, while joining the majority, separately emphasized that a cash-or-equivalent requirement protected plans often controlled by the same interests as their employers. Don E. Williams, 429 U.S. at 583–588 (separate opinions).

Key takeaways

• Distinguish a bookkeeping accrual from an actual transfer to the plan.
• Verify the statutory deadline and grace-period rule for the employer’s tax year.
• Do not assume a secured demand note is the cash equivalent of a paid contribution.
• Coordinate deduction timing with current sections 401 and 404, plan administration, and funding requirements.
