Welch v. Henry
The Court upheld a Wisconsin law that retroactively taxed 1933 corporate dividends at special rates to raise emergency relief funds, ruling that the tax violated neither equal protection nor due process.
The decision confirms that states and Congress have significant leeway to tax income retroactively, especially when doing so at the first legislative opportunity after learning how much revenue is needed and available.
“Any classification of taxation is permissible which has reasonable relation to a legitimate end of governmental action.”
The Court's general standard for judging whether a tax classification violates equal protection.
How it got here: The taxpayer paid the tax under protest, sued in Wisconsin state court, lost when the Wisconsin Supreme Court upheld the tax, and appealed directly to the U.S. Supreme Court.
The Case in Depth
What happened
A Wisconsin resident received dividend income in 1933 that was fully deductible from taxable income under the state's tax law at the time, so he owed no state income tax that year. Two years later, facing a need for unemployment relief funding, the Wisconsin legislature passed a special retroactive tax specifically targeting those previously tax-free 1933 dividends, applying different rates and fewer deductions than applied to other income earned that year.
The question before the Court
Could Wisconsin pass a 1935 law taxing 1933 dividend income that had been tax-free when it was received, without violating the Constitution's fairness guarantees?
The Court's answer
Yes — the Court ruled that Wisconsin's retroactive 1935 tax on 1933 dividend income violated neither equal protection nor due process. Wisconsin had long treated these dividends as a distinct class, and because they had escaped taxation entirely in 1933, taxing them later to meet a new revenue need was a rational, non-arbitrary way to distribute the tax burden, even at different rates and with fewer deductions than other income received.
On due process, the Court distinguished this tax from earlier invalidated retroactive gift taxes, which punished a taxpayer's one-time voluntary choice made without warning of a future tax. Receiving dividends involves no comparable irrevocable choice, and lawmakers have long taxed a prior year's income at the first legislative session after it is known — here, 1935 for 1933 income — without violating the Constitution.

Why it matters
Taxpayers who benefited from an exemption or deduction one year cannot assume that income is permanently safe from later taxation once a legislature revisits its revenue needs. The ruling gives state and federal lawmakers broad room to reshuffle tax burdens retroactively, within roughly a year or two, when responding to funding shortfalls like unemployment relief.
What changes now
The ruling is a final decision on the merits, affirming the Wisconsin Supreme Court's judgment that upheld the tax. The taxpayer's payment stands, and no further proceedings are directed. The decision stood as guidance for how far back state and federal legislatures could reach when imposing new taxes on previously untaxed or differently taxed income from a recent prior year.
What this does not decide
The Court did not decide how far back a retroactive tax could reach before becoming unconstitutional, noting only that this particular one-to-two-year retroactive reach, applied at the first legislative opportunity, did not cross that line. It left open whether taxing more distant past income would be permissible.

Dissent — Justice Roberts
“The illegal discrimination and the arbitrary character of the Act condemn it under the equal protection clause not because it selects a particular class of citizens for the imposition of the tax but because, in so doing, it reaches back and singles out for a new and wholly different sort of income tax those few only to whom a specific deduction was allowed”Roberts' central objection that the law unfairly targeted taxpayers who had relied on a lawful deduction.
Justice Roberts argued the law was arbitrary and discriminatory because it singled out a narrow class of taxpayers who had lawfully relied on a dividend deduction, taxing only that specific slice of their past income at new, harsher rates while leaving other 1933 income earners untouched. He distinguished this from ordinary retroactive tax revisions, which continue an existing system taxpayers knew might be amended, arguing that here taxpayers could not have foreseen this entirely new, targeted tax when they filed and paid in 1934.

How the Court got there
The legal reasoning, step by step
- The Court asked whether the special dividend tax created a classification without a reasonable relationship to a legitimate government purpose, since equal protection allows differing tax treatment only when the distinction is not arbitrary or capricious.
- It found that Wisconsin had long treated dividends from certain Wisconsin-based corporations as a distinct category for tax purposes, sometimes exempting them entirely, so singling them out again for new taxation followed a consistent, non-arbitrary pattern rather than random hostility.
- Because these dividends had escaped all taxation during 1933, the Court reasoned that taxing this previously untaxed class to help cover new relief costs was a rational way to spread the tax burden, even though other income types were taxed differently.
- Turning to due process, the Court distinguished this income tax from earlier invalidated gift taxes, explaining that gift taxes were struck down because a taxpayer's voluntary, one-time choice to give could not have accounted for a later, unforeseen tax; receiving dividends does not involve that same kind of irreversible choice made in reliance on the existing tax rules.
- The Court noted a long, unbroken practice by Congress and Wisconsin of retroactively taxing income from the year of a legislative session or the year just before it, and held that this practice has consistently been found consistent with due process.
- Since the 1935 law was passed at the first legislative session after the 1933 tax returns became available, the Court concluded the retroactive reach was not so excessive as to be arbitrary or oppressive, even though the state's own supreme court described the law as approaching the limits of permissible retroactivity.
