Background
Ohio’s financial-institutions tax applies to a bank’s Ohio equity capital, calculated by multiplying its total equity capital by the share of its gross receipts attributable to Ohio. The tax uses declining rates as Ohio equity capital increases: 0.8 percent on the first $200 million, 0.4 percent on the next $1.1 billion, and 0.25 percent above that amount.
Dollar Bank, a Pittsburgh-based federal savings bank with branches in several states including Ohio, sought refunds for tax years 2016 through 2020. It argued that the regressive rate structure disadvantaged interstate banks because a bank spreading its business among states could pay more in aggregate tax than a similarly sized bank conducting all its business in Ohio. The tax commissioner denied the claims, and the Board of Tax Appeals affirmed.
The Court’s Holding
The Supreme Court of Ohio affirmed. It held that the financial-institutions tax is internally consistent under the dormant Commerce Clause because, if every state adopted the same system, each state would tax only the portion of a bank’s equity capital apportioned to that state. The structure therefore does not create double taxation.
The court also held that the tax does not discriminate against interstate commerce. Banks with the same amount of Ohio equity capital face the same Ohio rates regardless of whether they operate only in Ohio or in multiple states. Any higher aggregate burden on a multistate bank results from its conducting less business in any one state, not from an interstate-specific tax or an in-state exemption. The court rejected Dollar Bank’s proposed aggregation-based version of the internal-consistency test and summarily rejected its repackaged due-process claim.
Key Takeaways
- Ohio may apply declining tax rates based on a bank’s Ohio-apportioned equity capital.
- Internal consistency asks whether identical state regimes would cause double taxation or inherent discrimination, not merely whether multistate operations produce a higher aggregate tax bill.
- A tax incentive to conduct more business within a state does not alone violate the dormant Commerce Clause when interstate and intrastate taxpayers are treated evenhandedly.
Why It Matters
The decision preserves Ohio’s financial-institutions tax structure and rejects a constitutional theory that could have put regressive state tax rates at risk whenever multistate businesses pay more overall than businesses concentrated in one state.
For state-tax litigants, the opinion emphasizes that a valid internal-consistency challenge requires more than a comparative effective-rate calculation: the tax must inherently subject interstate commerce to duplicative taxation or unequal treatment.
