Steward MacHine Co. v. Davis
The Supreme Court upheld the unemployment-compensation tax in the Social Security Act of 1935, ruling that Congress could tax employers while letting them credit most of that tax against payments into a state unemployment program, without unconstitutionally coercing the states.
The 5-4 decision cleared the way for the nationwide unemployment insurance system that still operates today, rejecting arguments that the tax invaded powers the Constitution reserves to the states.
“The difficulty with the petitioner's contention is that it confuses motive with coercion.”
The Court's core reasoning for why the tax credit did not unlawfully coerce states.
How it got here: A federal trial court dismissed the company's refund suit; the Fifth Circuit affirmed; the Supreme Court agreed to hear the case because of the important constitutional question involved.
The Case in Depth
What happened
An Alabama corporation paid the new federal payroll tax created by the Social Security Act, which funded unemployment compensation, and then sued to get its $46.14 payment back. It argued the tax was unconstitutional because it wasn't a proper excise, discriminated arbitrarily among employers, and pressured states into adopting unemployment insurance laws against their will.
The question before the Court
Could Congress tax employers and let them offset most of that tax by paying into a state unemployment fund, without illegally forcing states to adopt unemployment insurance laws?
The Court's answer
Yes — the Court upheld the tax. It ruled the payroll tax was a valid excise that Congress could impose uniformly nationwide, that its exemptions for small employers and certain job categories were reasonable rather than arbitrary, and that letting employers offset up to 90% of the tax by paying into an approved state unemployment fund did not unlawfully coerce states into adopting such programs.
The Court reasoned that offering a financial incentive is different from compulsion: Alabama chose freely to pass its own unemployment law, was not bound by contract to keep it, and could repeal it at any time without penalty beyond losing the credit. Because the credit was tied to a real problem the federal tax itself was addressing — unemployment relief — inducing states to act was lawful cooperation, not coercion.

Why it matters
The ruling let a key piece of the New Deal's safety net survive, allowing the federal-state unemployment insurance system that still pays jobless workers today to take root. It also gave Congress a workable model — taxing nationally while crediting compliance with state programs — for prodding states into cooperative programs without directly commanding them.
What changes now
The decision is a final merits ruling with no remand needed; the lower courts' judgments for the government stand, and the Social Security Act's unemployment tax and credit scheme remained in force. The ruling, decided alongside companion cases upholding related Social Security provisions, cleared the constitutional path for the federal-state unemployment insurance system that continued to operate afterward, though the Court explicitly left open how far a similar tax-and-credit device could go in other contexts.
What this does not decide
The Court expressly declined to say a tax is valid whenever it lets a state escape the tax by adopting an unrelated law, and it did not fix the outer limit of how much federal financial pressure on states is permissible. It resolved only that this particular tax-and-credit combination, tied closely to the shared problem of unemployment relief, did not cross the line into coercion.
Concurrences and dissents
Dissent — Justice McReynolds
“Unfortunately, the decision just announced opens the way for practical annihilation of this theory; and no cloud of words or ostentatious parade of irrelevant statistics should be permitted to obscure that fact.”McReynolds's warning that the ruling threatens state sovereignty and self-government.
Justice McReynolds argued the law unconstitutionally interferes with states' orderly self-government, quoting Texas v. White on the indestructibility of the states and invoking President Pierce's 1854 veto message warning against federal intrusion into matters of local concern. He warned the decision opens the door to unlimited federal control over state policy through the combination of taxes and conditional relief from them.
Dissent in part — Justice Sutherland
Justice Sutherland agreed the payroll tax itself was a valid excise and that the credit scheme did not coerce states into adopting unemployment laws. But he argued the act's administrative provisions unconstitutionally forced states to surrender control over their unemployment funds by requiring deposits with the federal Treasury under conditions only the federal government could alter, invading powers reserved to the states under the Tenth Amendment. He would have reversed the judgment.
Dissent — Justice Butler
Justice Butler joined the objections raised by both McReynolds and Sutherland and added that the broader 'tax and credit' device used throughout the Social Security Act could let federal officials control state policy in any area within state power, since Congress could keep increasing the tax pressure without limit. He would have reversed the judgment below.
How the Court got there
The legal reasoning, step by step
- The Court first asked whether the payroll tax counted as a lawful 'excise' — a tax on an activity or relation rather than a forbidden 'direct tax' requiring apportionment among the states by population. It concluded that employment is a business relation that, like property, can be taxed as of common right, so the tax qualified as an excise (or, if not, still an impost or duty) subject only to the requirement of geographic uniformity, which the flat nationwide rate satisfied.
- Next the Court considered whether the tax's exemptions — for employers with fewer than eight workers, agricultural labor, and domestic service — violated the Fifth Amendment's fairness guarantee. Applying the same relaxed standard courts use for state tax classifications under the Fourteenth Amendment's equal protection clause, the Court found the line-drawing reasonable and not arbitrary.
- The Court then addressed the central federalism question: whether combining the tax with a 90% credit for payments into an approved state unemployment fund amounted to unconstitutional coercion of the states under the Tenth Amendment. It held that inducement through a financial incentive is not the same as coercion, comparing the credit to a permissible tax rebate that merely makes compliance attractive rather than compelling it.
- Applying that distinction to the facts, the Court noted Alabama passed its unemployment law knowing it could repeal it anytime without penalty beyond losing the credit, and that no federal contract bound the state to keep the law in force — showing its choice was voluntary rather than coerced.
- The Court also examined whether the state's arrangement to deposit unemployment funds with the U.S. Treasury for safekeeping and to have federal officials review compliance amounted to a forbidden surrender of state governmental power. It concluded the arrangement was based on a revocable statutory consent, not a binding contract, so the state retained full authority to withdraw its funds and end the relationship at will.
- Because the credit was closely tied to relieving the same nationwide unemployment problem the tax itself addressed, the Court concluded the inducement fell within permissible bounds, distinguishing this scheme from prior cases where a tax-and-penalty combination was used to regulate conduct unrelated to the tax's own purpose.
