The decision Supreme Court struck down the state’s ends months of suspense and attention on digital sales tax law (S.B. 106); South Dakota the future of e-commerce. In July 2017, a then brought the case to the U.S. Supreme House subcommittee heard testimony on Court, in hopes of overturning Quill. the right of states to collect sales taxes Although earlier estimates varied,7 a from out-of-state merchants that do not recent U.S. Government Accountability Office have a physical presence in the destination (GAO) report indicated that based on current state.1 Several states, eager to defend their law, state and local governments were right to tax remote sellers, had passed already able to collect most remote sales tax “notice and reporting” laws, which require revenues that would be owed.8 Most large remote sellers to either collect sales taxes or remote sellers are either established retailers submit an annual report of each consumer’s that already have physical stores in many purchases to the state government.2 Some states, or have entered into agreements states have targeted marketplace providers with state governments to voluntarily collect such as and eBay, which previously sales taxes regardless of physical presence. have not collected all sales taxes from However, the study showed that if states In a split 5-4 decision, third-party sellers.3 Not absent from the could require out-of-state merchants e-commerce debate is President Donald without a physical presence to collect sales the U.S. Supreme Court Trump, who in March 2018 posted a tweet taxes, states would be able to expand their overturned Quill and accusing Amazon of treating the U.S. Postal collectible sales tax revenue by $8 to $13 ruled that states can Service as its “delivery boy” and of paying billion in aggregate for 2017.9 For states that charge out-of-state 4 little taxes to state and local governments. do not have personal income taxes and rely retailers sales tax even This issue brief reviews the implications heavily on sales taxes, such as Texas, the of the U.S. Supreme Court ruling and the revenue gain is close to the $1 billion range.10 if they do not have a legislative developments in online sales The report further provided segregated physical presence in taxation over the last 12 months. estimates showing that collectible rates and the state. associated revenue gains vary significantly by different types of sellers.

Because large retailers are generally disagreed that compliance costs already collecting the taxes, changing the are prohibitively high, pointing to the current law means compliance burdens extensive use of computer technology by would mostly fall on small- and medium- merchants to reduce the burdens and the sized enterprises (SMEs). Quill challengers longstanding simplification effort by states interpreted the results differently—i.e., to expand the Streamlined Sales and Use Tax based on the perspective of SMEs—arguing Agreement (SSUTA).15 Under the agreement, that the lost revenue jeopardizes jobs collection and administration laws have at SMEs in local communities.

They costs increase. The issue is whether the argued that the physical presence rule obligations are excessively burdensome is outdated,11 especially considering the relative to the benefits, and whether the fact that the Quill ruling was based not on burdens are substantially different across its own constitutional merit, but on the states. Quill opponents have said that the principle of stare decisis12 that governs benefits outweigh the costs, and that the another 1967 Supreme Court ruling involving uneven compliance burden across states mail order retailers.13 The Bellas Hess case can be resolved by replacing the physical was ruled 50 years ago, before the invention presence rule with a balancing test: one of the internet.

However, despite different interstate sales. opinions on Quill’s future, all three groups argued that Congress has the authority and should be the party to resolve the issue. STATE PERSPECTIVES The authors of the first brief, filed in Some state representatives expressed early March, stated that the South Dakota disagreement about Congress’ leadership law establishes that merchants have to role in addressing the issue and its need for have a significant connection to the state The court stated more time to reach a conclusion.

The senators the deadlock. suggested that overturning Quill will not leave remote sellers with excessive burdens, generally for the reasons discussed above. SUPREME COURT DECISION32 Finally, the brief stated that Congress is ready to act when needed, and that its In a split 5-4 decision, the Supreme Court inaction so far had been due to the fact that overruled both Quill and Bellas Hess, using the Founding Fathers deliberately organized strong words to indicate that the physical the government to deter hasty actions presence rule is unsound and incorrect. by Congress.
