On August 10, 2015, the Kansas Department of Revenue became the first state tax authority to directly respond to the U.S. Supreme Court's decision in Comptroller of the Treasury v. Wynne.1 The Department's issuance of a notice acquiesces to the Wynne decision and allows Kansas residents the ability to take a credit for taxes paid to other states and localities within those states, both on a prospective and retroactive basis.2
The Wynne Decision
On May 18, 2015, the U.S. Supreme Court affirmed a Maryland Court of Appeals decision concluding that the Maryland tax system (comprised of state-level and county-level components) was unconstitutional to the extent that it denied Maryland resident taxpayers a credit against the county-level tax for income taxes they paid to other states.3 Based on this decision, the taxpayer and similarly situated residents are now afforded the credit against both components of the Maryland tax. While the full reach of the Wynne decision is not yet known, several states have been compelled to consider whether their state tax credits offered to residents may run into similar constitutional issues without explicit inclusion of local taxes within the scope of such credits.
