Wisconsin Central Ltd. v. United States
The Supreme Court ruled that employee stock options are not taxable "compensation" under the Railroad Retirement Tax Act, because stock options are not "money."
The 5-4 decision means railroads and their workers do not owe retirement taxes on stock options, resolving a split among lower courts over how to read a decades-old pension tax law.
“Pretty obviously, stock options do not fall within that definition.”
The majority explaining why stock options don't count as currency or a medium of exchange.
How it got here: Lower courts split on the issue; the Seventh Circuit ruled for the government, and the railroads asked the Supreme Court to resolve the conflict.
The Case in Depth
What happened
During the Great Depression, Congress created a special retirement tax and pension system just for railroad workers, taxing "money remuneration." Decades later, some railroads began giving employees stock options as part of their pay. The federal government argued these stock options should be taxed as compensation under the law; the railroads and their employees disagreed, arguing stock options aren't money.
The question before the Court
When a railroad gives an employee stock options, does that count as taxable "money remuneration" under the federal railroad retirement tax law?
Why it matters
Railroads and their employees who use stock option plans will not owe railroad retirement taxes on those options, potentially saving companies and workers money and affecting how much employees eventually receive as retirement benefits. The ruling also signals how the Court will read old statutory terms going forward, favoring their meaning at the time Congress wrote them.
What changes now
The case is sent back to the lower courts to apply the Court's reading that stock options are not taxable money remuneration under the Railroad Retirement Tax Act. This is a final decision on the legal question, though further proceedings will work out its application to the specific stock plans at issue. Other pending railroad tax disputes involving stock options will likely be resolved the same way.
Concurrences and dissents
Dissent — Justice Breyer
Justice Breyer argued the term "money remuneration" is ambiguous, since dictionaries from the 1930s also defined money more broadly to include property convertible into cash. He would have deferred to the government's longstanding practice of taxing stock options, noting that many employees convert their options directly into cash and that the statute's purpose was to fund a stable pension system, not to exclude financial instruments like stock options.
How the Court got there
The legal reasoning, step by step
- The Court applied the rule that statutory words are given their ordinary meaning at the time Congress wrote the law, so it looked to 1930s dictionaries defining "money" as currency serving as a medium of exchange.
- Applying that definition, the Court found stock options don't qualify as money because people don't ordinarily use stock to buy groceries or pay rent, even though stock can be sold for cash.
- The Court read the word "remuneration" as broadening the forms money can take (cash, checks, wire transfers), not as broadening what counts as money in the first place.
- Looking at surrounding law, the Court noted that the 1939 tax code and a companion Social Security tax law (which taxes "all remuneration," not just money) both treated stock and money as distinct categories, showing Congress knew how to tax non-cash benefits when it wanted to.
- The Court concluded that a 1938 IRS regulation, which listed things like salaries and wages as taxable but never mentioned stock, supported reading "money" to exclude stock.
- Because the statutory text was clear on its own, the Court declined to give deference to a more recent IRS regulation equating the railroad tax law's terms with the broader Social Security tax law.
