Purpose
As the popularity of online shopping has grown, states have seen their sales tax revenues drop. The Supreme Court has ruled that states cannot require a company to collect sales tax on transactions with their residents when the company has no physical presence in the state. Federal legislation has been introduced over the past several years to authorize online sales tax collection. With small business owners on both sides of the issue, the Office of Advocacy recognized the need for objective research for small businesses and policymakers. This report analyzes the number of firms that will be affected by the small seller exemption (SSE) if current legislation passes and how much e-commerce is likely to be affected.
Background
Sales taxes are a critical component of state and local government revenue systems in the United States, contributing nearly one-third of all state taxes and nearly one-quarter of all state and local taxes. All but five states (Alaska, Delaware, Montana, New Hampshire, and Oregon) currently impose a sales tax (Figure 1). In 2012, state sales taxes brought in $243 billion, or approximately 1.6 percent of gross state product. (This was a slightly smaller share than in 2011.)
According to the U.S. Census Bureau, online sales accounted for approximately 5.3 percent of total retail sales in the second quarter of 2013. While online sales still represent a small share of total sales, they are expected to grow significantly in the future.
Sales tax systems are facing significant pressure for a number of reasons, including the growth in online and other remote transactions between in-state buyers and out-of-state sellers. The Courts have ruled that businesses must have nexus—typically physical presence—in a state before they can be taxed by a state or required to collect and remit the state’s taxes.[1] The Courts have also determined that only Congress has the authority to redefine nexus (i.e., what constitutes a vendor’s presence in a state).
More recently, some cash-strapped states have tried to redefine what it means to have physical presence (i.e., what constitutes nexus) for out-of-state vendors. This has created complex and often inconsistent taxation rules of online commerce among the states.
At the same time, brick-and-mortar retailers, who have always been obliged to charge taxes for sales transactions, began voicing concern that online retailers did not share the same responsibility. These brick-and-mortar retailers suggested that it was unfair that online retailers could charge lower prices as a result of not being forced to remit taxes on sales transactions.
As a result of these developments, some policy groups and legislators have tried to develop a tax policy framework for states and online retailers that is consistent, fair for all retailers, and not overly burdensome for small business. In the 113th Congress, both chambers introduced bills to address some of these issues. The Marketplace Fairness Act of 2013 (S.743) offers states two methods of simplification: states can join the Streamlined Sales and Use Tax Agreement or they can adopt a set of simplification guidelines in the bill. The legislation would also provide for a $1 million small seller exemption.[
Overall Findings
The most commonly discussed small seller exemption (SSE) in the proposed bills has been $1 million. This report calculates that 974 of the Internet Retailer Top 1,000 companies have sales exceeding $1 million. The study’s authors use established statistical techniques to account for the possibility that some larger firms are not included in the Internet Retailer data. This generates a more realistic estimate of 1,817 online retailers that could be subject to the requirements of the Marketplace Fairness Act. In either case, the number of included retailers is a very small fraction of all online sellers.
An SSE of $1 million would subject only a small share of business to the internet sales tax: less than 4.5 percent of electronic shopping and mail order houses and less than 2 percent of all non-store retailers. However, the volume of sales transactions subject to the tax would represent 57 percent of total U.S. online retail sales. A higher SSE of $5 million would affect an even smaller share of online retailers, but the share of online sales affected would remain near 57 percent (see Table 1).
Determining the impact of sales tax legislation on actual collections is complicated by the fact that many of these firms are already collecting sales taxes for a large number of states in which they currently have nexus. The study examined a sample of online retailers representing 231 of the Internet Retailer Top 1,000 companies. As shown in Figure 2, 38 of the surveyed companies (16 percent of the total) collected sales taxes for all 45 sales-taxing states. Only 8 of the surveyed companies (3 percent of the total) do not collect any sales tax, and 57 (25 percent of the total) collect in only one state. The average online retailer among the 231 in the sample collects sales taxes in about 18 states, representing about 47 percent of the total national state and local sales tax collections.
