Congress Must Act to Stop State Interference with Interstate Commerce

The U.S. Supreme Court has never upheld a state attempt to tax interstate commerce in the absence of physical presence of the taxpayer in the taxing jurisdiction. Ignoring this fact, some states are attempting to use "economic nexus" theories to expand their tax base by assessing income and franchise taxes against out-of-state companies that have customers but no property or employees in the taxing state. Such efforts violate the U.S. Constitution by unduly burdening the free flow of interstate commerce.

Efforts by state taxing officials to apply "economic nexus" theories to raise additional revenue from out-of-state entities are sure to increase dramatically in light of a recent refusal by the U.S. Supreme Court to review two cases that challenged the constitutionality of such schemes.

Congress has an obligation to act to provide relief from the resulting chaos by clarifying that state tax jurisdiction over out-of-state businesses is limited to those entities that engage in activity, through some form of physical presence, within the state's bounds.

If Congress fails to act, problems caused by state overreaching will increase. Already, overly-aggressive state attempts to expand taxing authority has:

  • led to unfairness and uncertainty;
  • increased compliance costs (inevitably, such increased costs will be passed on to consumers in the form of higher prices);
  • hindered business expansion;
  • put companies at the risk of duplicative over-taxation;
  • threatened the continued development of electronic commerce;
  • threatened the revenue collections of states that fully comply with constitutional nexus requirements;
  • stymied the intent of accounting reporting rules for publicly traded companies; and
  • negatively affected international competitiveness.

Left unchecked, this unwarranted expansion of the states' power to impose business activity taxes on companies that do business across state lines will have a chilling effect on the entire economy as tax burdens, compliance costs, litigation and uncertainty escalate.
