US Supreme Court denies cert in taxpayer challenges to MI and WA retroactive tax law amendments
Multistate Tax alert | May 22, 2017
The US Supreme Court, in a May 22, 2017 order, has refused to hear taxpayer challenges to retroactive tax legislation enacted in Washington and Michigan. In both instances, taxpayers had contended that the retroactive application of the tax law changes violated the Due Process Clause of the US Constitution.
In the May 22,
The appeal in Michigan stemmed from taxpayer challenges to the 2014 enactment of Public Act 282 (PA 282), which had retroactively rescinded Michigan’s membership in the Multistate Tax Compact (Compact) effective January 1, 2008. This retroactive element of PA 282 neutralized the election provided under Article III of the Compact by which certain taxpayers had previously sought to compute their Michigan Business Tax (MBT) liability pursuant to the Compact’s equally weighted, three-factor apportionment formula.
In 2015 and 2016, Michigan courts had rejected taxpayer challenges that the retroactive element of PA 282 violated the Due Process Clause of the US and Michigan constitutions, among other claims.
Unless the Supreme Court grants a petition for rehearing, the Compact litigation in Michigan has ended, and the weighting of the apportionment formula pursuant to the Compact Election has been resolved for Michigan tax purposes in favor of the state. Accordingly, application of the single sales factor apportionment formula, as provided under the MBT Act pursuant to MCL § 208.1301(2) and the Corporate Income Tax Act pursuant to MCL § 208.663(1), is required.
It is anticipated that within the coming months the Michigan Department of Treasury will issue guidance outlining the procedures for resolving pending MBT compact cases impacted by the denial of the taxpayer challenges to PA 282.
