Several states continue to move forward with the taxation of digital advertising and new tax proposals have entered the fray.  We last updated you on the attempts by Maryland, Nebraska, and New York.  Nebraska had a hearing on its sales tax bill in February, with relatively little movement after that.  In contrast, Maryland and New York have continued their move towards imposing taxes on digital advertising in some form and West Virginia has entered the mix.

Massachusetts recently joined a handful of other states (read: States over the Edge and Testing Boundaries with Business Activity Tax Nexus) by issuing a final revised regulation adopting a bright-line, $500,000, nexus threshold for its corporate excise tax. See generally 830 CMR 63.39.1. Echoing the language of the Wayfair decision, the state’s revised nexus regulation provides that “the Commissioner will presume that a general business corporation’s virtual and economic contacts subject the corporation to the tax jurisdiction of Massachusetts under M.G.L. c. 63, § 39, where the volume of the corporation’s Massachusetts sales for the taxable year exceeds five hundred thousand dollars.” 830 CMR 63.39.1(3)(d).

Wayfair has, for now, answered the question (at least, in part) of whether economic activity creates substantial nexus under the Commerce Clause for purposes of sales and use taxes. However, questions remain regarding whether and to what extent business activity tax nexus standards could be impacted. While states had boldly asserted economic nexus in the business activity tax context pre-Wayfair, the response since has been somewhat muted, until recently. Three states, Pennsylvania, Texas, and Wisconsin, have recently sought to fill in the blanks with regard to business activity tax nexus, with varied and inconsistent results that may raise more questions and concerns than answers.

Statutory definitions often carry ambiguous terms and subtle distinctions. However small these distinctions may seem, their interpretation can mean millions in state tax.  In Massachusetts, for example, multistate corporations generally apportion their business income using a three-factor formula based on a property factor, a payroll factor, and a double-weighted sales factor.  However, certain out-of-state corporations, like “manufacturing corporations” or “mutual fund service corporations,” may be required to apportion their business income using Massachusetts’s single-sales factor apportionment formula.  In the event a single-sales factor apportionment formula applies, an out-of-state company’s Massachusetts corporate excise tax liability may increase, as none of that company’s out-of-state property and payroll expenses are accounted for in apportioning income.
