25 States Say Trump's Tariffs Are an Illegal Tax, and They're Right

A coalition is asking the courts to do what Congress will not: enforce the constitutional rule that the legislature, not a President, has the power to impose taxes. The mechanism being challenged is Section 232 of the Trade Expansion Act and Section 301 of the Trade Act of 1974, both of which hand the executive broad discretion to slap tariffs on imports when "national security" is invoked. The legal argument is that those laws delegated away something the Constitution forbids delegating: the taxing power itself.

The Tax That Refuses Its Name

The tariffs hit in 2026 with rates between 25% and 60% on goods from China, Mexico, and other major trading partners. Call them duties or call them trade tools, but the mechanic is identical to a sales tax. Money is collected at the border. The price of the good increases. Consumers pay more. State governments, which purchase steel for bridges, aluminum for school buses, and electronics for hospital systems, now face budget shortfalls they did not appropriate for.

The lawsuit names this plainly. These are taxes. They were imposed by executive order. And Article I, Section 8 of the Constitution gives the power to "lay and collect taxes, duties, imposts, and excises" to Congress, not the President. The administration did not go to the House of Representatives for a vote. It cited national security under Section 232 and moved unilaterally.

The question is whether "national security" can mean anything the executive wants it to mean. The Trade Expansion Act allows tariffs when imports threaten defense readiness or critical infrastructure. In practice, the administration has applied that standard to Canadian lumber, Mexican tomatoes, and Chinese-made semiconductors. The national security claim has become a universal pass-through.

Where the Delegation Breaks

Congress has been handing trade authority to Presidents since the Reciprocal Trade Agreements Act of 1934. The delegation was supposed to be limited. Presidents could negotiate deals within defined parameters. Section 232 and Section 301 widened the lane. By the time you reach 2026, the lane has no edges. The President names the threat, sets the rate, picks the countries, and collects the revenue. At what point does a delegation become an abdication?

The 25 states argue that point was crossed. They are not claiming the President cannot negotiate trade deals or respond to genuine threats. They are claiming he cannot unilaterally raise $30 billion in annual revenue without legislative approval. That number is not speculative. It is the tariff revenue collected in the first quarter of 2026, annualized.

The states also argue injury. When the cost of materials for a highway project in Ohio rises by 40%, the state must either cut the project or find money elsewhere in the budget. When hospital equipment in Michigan costs 25% more, the burden falls on Medicaid budgets. These are not abstract harms. They are line items.

The Counterargument Held Honestly

The administration's position is that tariffs are not taxes in the constitutional sense because they are tools of foreign policy, not revenue collection. The collected duties are incidental to the goal, which is leverage in trade negotiations. That distinction has legal precedent. The Supreme Court has historically granted the President wide latitude in foreign affairs.

The states' response is that incidental revenue stops being incidental when it runs into tens of billions and directly affects domestic budgets. The doctrine of non-delegation exists precisely to prevent this kind of end-run.

The lawsuit will likely reach the Supreme Court. If it succeeds, 90 years of expanding executive trade authority collapses. If it fails, the last remaining check on unilateral tariff policy disappears. Either way, the case forces an answer to a question Congress has avoided for decades: who actually has the power to tax Americans?
