United States v. Byrum

Background

A businessman, Milliken Byrum, put shares of three small, family-run companies into an irrevocable trust in 1958 and named a bank as trustee. He kept the right to vote the unlisted shares, to veto sales, to approve investments, and to replace the trustee. After his death the IRS said the trust shares should be taxed as part of his estate; the executor sued, won in the lower courts, and the case reached the Supreme Court.

Reasoning

The key question was whether Byrum’s retained voting power gave him a legal right to decide who would enjoy trust income. The Court said no. It distinguished earlier cases where a settlor had an express, legally enforceable power to allocate income. Byrum’s influence was indirect: directors, not he, legally declare dividends; trustees, not he, decide whether to pay or accumulate income; and fiduciary duties and business uncertainties limit what a controlling shareholder can lawfully force. Because Byrum had no ascertainable, enforceable right in the trust instrument to control income payments, the Court held the trust stock was not part of his taxable estate.

Real world impact

The decision protects many estate plans that use irrevocable trusts for closely held companies where control is exercised through voting power but no explicit legal right to allocate trust income is reserved. It narrows when the IRS can treat informal control as a retained legal right, though different facts could lead to a different result.

Dissents or concurrances

Justice White dissented, warning that retaining voting control effectively lets a person “open or close the spigot” of dividends and thus control who benefits, arguing the statute should reach such de facto control and that the majority creates a tax loophole.
