First Nat. Bank of Chicago v. United States

Background

A commercial bank filed a consolidated corporate income tax return that included results from two affiliated farm-loan banks organized under the Federal Farm Loan Act. The consolidated return claimed deductions for interest the farm-loan banks paid or accrued on their bonds. The tax Commissioner denied those deductions, the bank sued in the Court of Claims and lost, and the case reached the Court for review.

Reasoning

The central question was whether a taxable bank may deduct interest on debt that was incurred to buy or carry securities whose interest is entirely exempt from tax. The Court examined the Revenue Act of 1921 and the Federal Farm Loan Act and found the farm mortgages and loans held by the joint-stock land banks qualified as securities whose interest is tax-exempt. The Court concluded the bonds were issued to carry or purchase those exempt obligations, and that allowing the deduction would enable a taxable commercial bank to escape tax by affiliating with an exempt farm-loan bank. The Court affirmed the lower court’s denial of the claimed deductions.

Real world impact

Taxable commercial banks cannot reduce their federal income tax bill simply by affiliating with joint-stock land banks that hold tax-exempt farm loan securities. The joint-stock land banks remain tax-exempt and do not pay federal income tax; the decision preserves the statutory rule preventing deduction for interest tied to acquiring exempt securities.
