Robert C. Steiner and Wendy Steiner-Reed v. Utah State Tax Commission

Summary

The Utah Supreme Court reviews challenges by Utah resident taxpayers to the treatment of income earned outside Utah and in foreign countries. The court holds that the Dormant Commerce Clause and Dormant Foreign Commerce Clause do not require Utah to apportion the taxpayers' income or allow deductions for foreign income. It also concludes that Utah Code section 59-10-115(2) does not require the claimed foreign-income deduction, affirming in part and reversing in part the tax court's ruling.

Holdings

1. Utah's residency-based income tax system, which taxes residents' income and provides a credit for qualifying taxes paid to other states, satisfies the internal-consistency requirement of the Dormant Commerce Clause. The Constitution therefore does not require Utah to apportion the Steiners' income instead.
2. The Dormant Foreign Commerce Clause did not require Utah to grant the Steiners a deduction or credit for foreign income taxes. The court declined to extend foreign-commerce protections to individual taxpayers or S corporation shareholders absent controlling United States Supreme Court precedent.
3. Utah Code section 59-10-115(2) authorizes an equitable adjustment only when the Utah tax code itself imposes the double tax detriment. It does not authorize an adjustment merely because foreign income is taxed by Utah and a foreign sovereign.

Questions Presented

1. Whether the Dormant Commerce Clause required Utah to apportion the Steiners' residency-based income tax rather than provide a credit for taxes paid to other states.
2. Whether the Dormant Foreign Commerce Clause required Utah to allow a deduction or credit for income earned in foreign countries.
3. Whether Utah Code section 59-10-115(2) required an equitable adjustment excluding the Steiners' foreign income from Utah taxable income.
