For companies doing business in multiple states, determining state tax responsibilities has always been a challenge. However, 2018 was a notably busy year. The Tax Cuts and Jobs Act (TCJA) brought federal legislation that left states needing to react quickly, and with tax reform 2.0 looming, the challenges are not over.

Even more dramatic was the U.S. Supreme Court’s decision in South Dakota v. Wayfair, bringing the end to the longstanding physical presence nexus precedent. States are quickly reacting, and economic nexus laws are rapidly becoming the norm.

When it comes to understanding and acting on these dramatic changes, middle market companies have a lot to deal with and must determine what to handle now, and what to deal with later.

Our 2018 state and local tax recap explores noteworthy changes and introduces information on the following (and more):

  • State reactions to the Tax Cuts and Jobs and the possibility of tax reform 2.0
  • Wayfair and sales tax nexus
  • Increased state amnesty activity
  • Rate changes, sourcing and apportionment
