After Wayfair: What Are State Use Taxes Worth?

Abstract

The U.S. Supreme Court ruling in South Dakota v. Wayfair, Inc. that states may require sellers without a physical presence to collect use taxes has generated much enthusiasm and dread among observers. We present new data on revenues from the state use tax between 2010 and 2017. We also present a unique monthly series of remote vendor use tax collections for Indiana before and after the Wayfair ruling and use the synthetic control method to derive a treatment effect of the policy change. While remote vendor registrations have tripled, we find there have been relatively modest impacts on state revenue.
