## Facts

- Minnesota enacted the Minnesota Income Tax Act, which imposed an income/franchise tax on certain entities.
- The Act expressly exempted credit unions from the income or franchise tax.
- Savings and loan associations (including federally chartered savings and loan associations) were not included in the exemption.
- Credit unions and savings associations shared several features: both accepted funds from local depositors, made loans to members, granted member voting rights, and were required to maintain substantial reserves.
- The institutions also differed in several ways:
  - Savings associations primarily made loans secured by real property; credit unions made mostly personal loans, with real-estate-secured lending playing a smaller role.
  - Credit unions served members connected by a common bond or group membership, creating a community of interest; savings associations served a broader and less defined customer group.
  - Credit unions were supervised by a state official; savings associations were supervised by a federal board.
- Minnesota Federal Savings & Loan Association was a federally chartered savings-and-loan association and therefore was not eligible for the credit-union exemption.
- The State of Minnesota brought an action to collect the tax Minnesota Federal owed under the Act (for the relevant tax year), and the trial court entered judgment for the State.
- Minnesota Federal appealed, arguing that exempting credit unions while taxing savings associations violated the Minnesota Constitution’s uniformity requirement and the Equal Protection Clause of the Fourteenth Amendment.

## Issues

1. Whether the Minnesota Income Tax Act’s exemption for credit unions, while taxing savings and loan associations, violates the Minnesota Constitution’s uniformity provision.
2. Whether the same classification violates the Equal Protection Clause of the Fourteenth Amendment.

## Decision

- The Minnesota Supreme Court affirmed the judgment for the State.
- The court held that exempting credit unions while taxing savings and loan associations did not violate the Minnesota Constitution’s uniformity provision.
- The court held that the classification also did not violate the Equal Protection Clause of the Fourteenth Amendment.
- The court concluded that differences in lending practices, membership base, and regulatory oversight supplied a reasonable basis for treating the two types of institutions as separate classes for tax purposes.

## Legal Principles

- The legislature has broad discretion to create classifications for taxation, and a classification will be upheld if any reasonable state of facts can justify it.
- A tax satisfies state uniformity requirements when it operates uniformly on those within the same class and the class line rests on real and substantial differences rather than arbitrary selection.
- Equal protection permits tax classifications that are reasonable; the Constitution does not require identical tax treatment for entities that the legislature could rationally view as different.
- Differences relevant to the reasonableness of a tax classification may include the kind of lending an institution principally conducts (property-secured vs. personal lending), the nature and limits of membership or customer eligibility (common-bond membership vs. open and undefined customer base), and the institution’s supervisory framework (state vs. federal).

## Conclusion

Minnesota’s decision to exempt credit unions from the income/franchise tax while taxing savings and loan associations survived both state uniformity and federal equal protection review because the legislature could reasonably treat the two groups as different classes based on their lending focus, membership structure, and regulatory supervision, and the tax applied consistently within each class.
