Oregon bars use of three-factor apportionment formula
USA | May 11 2018

The Oregon Supreme Court has rejected a business taxpayer's constitutional challenges to a 1993 Oregon statute that eliminated the right to utilise a three-factor apportionment formula in calculating Oregon income tax. The Oregon Supreme Court joined courts in Texas, Minnesota, California and Michigan in rejecting taxpayer arguments that states which have enacted Article IV of the Multi-state Tax Compact have entered into a binding contractual obligation which may not be overridden.
