Director of Revenue of Missouri v. CoBank ACB
The Supreme Court ruled that banks for cooperatives, part of the federally created Farm Credit System, are not automatically immune from state income taxes just because Congress labeled them federal instrumentalities.
The decision reverses the Missouri Supreme Court and confirms that Congress's decades-long structure of the Farm Credit Act — granting explicit tax exemptions to some farm-credit institutions but not others — means banks for cooperatives can be taxed by the states.
How it got here: Missouri's tax agency denied a refund, an administrative commission agreed, but the Missouri Supreme Court reversed and held the bank tax-exempt; Missouri sought Supreme Court review.
The Case in Depth
What happened
CoBank ACB, successor to the National Bank for Cooperatives, is part of the Farm Credit System that Congress created to lend money to farm cooperatives. After paying Missouri corporate income taxes from 1991 to 1994, the bank sought refunds, claiming that as a federal instrumentality it was constitutionally immune from state taxation absent an express congressional waiver.
The question before the Court
Does a federal law bank for farm cooperatives have to pay state income taxes, even though Congress calls it a federal instrumentality?
Why it matters
Banks for cooperatives across the Farm Credit System will now have to pay state corporate income taxes, as they did for decades before a 1985 statutory cleanup was misread as removing that obligation. States gain a confirmed source of tax revenue from these lending institutions, and other farm-credit entities can look to the Act's explicit language to know whether they owe state taxes.
What changes now
The case is sent back to the Missouri Supreme Court for further proceedings consistent with the ruling that banks for cooperatives are not immune from state income taxation. This is a final decision on the merits resolving a split among state and federal appellate courts over whether Farm Credit System institutions owe state income tax, so similar disputes involving banks for cooperatives and production credit associations should now be resolved the same way.
How the Court got there
The legal reasoning, step by step
- The Court explained that a federal instrumentality only gets automatic constitutional tax immunity when Congress has said nothing about the matter; but here Congress had actually addressed the question of state taxation of these banks, so the implied-immunity doctrine from McCulloch v. Maryland never came into play.
- Tracing the statute's history, the Court found that since 1933 banks for cooperatives were subject to state income tax except during periods when the federal government held stock in them, and that rule survived unchanged through a 1971 amendment.
- The Court examined a 1985 amendment that deleted the sentences describing this stock-based exemption, and concluded the deletion was just a housekeeping fix removing language that had become meaningless once the government could no longer hold stock in the banks — not a hidden decision to grant full tax immunity.
- The Court found it implausible that Congress would make such a major change to fifty years of settled tax treatment through one of more than thirty similar technical deletions scattered through the law without saying so directly.
- Comparing the bank-for-cooperatives tax provision to the separate provisions covering farm credit banks and federal land bank associations, the Court noted that those other institutions were given clear, comprehensive tax exemptions in the statute's text, while banks for cooperatives were not, showing Congress knew how to grant full immunity when it wanted to.
Doctrinal impact

Distinguishes McCulloch v. Maryland (4 Wheat. 316)
The Court said this case's implied tax-immunity doctrine did not apply because Congress had already addressed the taxation question.
Distinguishes United States v. New Mexico (455 U.S. 720)
The Court noted this test for implied immunity was unnecessary to reach given the statutory answer here.
