New Sales Tax Report Shows a Decrease in Rate Changes in First Half of 2018

Annual Vertex Study Details Notable State Sales Tax Statistics

King of Prussia, PA

According to the annual mid-year tax rate study issued by Vertex Inc., a leading provider of tax technology and services, there were 318 sales tax rate changes in the first six months of 2018, a decrease from the same period in 2017. In addition, over the past 10 years there have been 6,414 new and changed sales and use tax rates.

“Although sales and use tax rate changes decreased from previous years, it was still an extremely active and surprising six months as tax professionals began to watch and assess the implications of the Supreme Court’s review of the South Dakota v. Wayfair decision,” said Bernadette Pinamont, Vertex vice president of tax research. “As a result of Wayfair, tax professionals are putting a greater focus on reviewing their end-to-end sales and use tax compliance processes, specifically registrations and exemption certificate management. Wayfair is not only impacting their economic nexus, but is also prompting companies to discuss processes, staffing and technology resources needed for tax.”

The Vertex 2018 Mid-Year Sales Tax Rate Report lists two state sales tax changes during the first half of 2018:

  • Effective January 1, 2018, New Jersey decreased their rate from 6.875% to 6.625%.
  • Guam has increased their Business Privilege Tax from 4.000% to 5.000%, effective April 1, 2018.

Additionally, the combined national sales tax rates average increased slightly to 10.0361 percent, up from 9.9819 percent in 2017.

  • Puerto Rico currently has the highest state sales tax rate at 10.50 percent with an additional one percent local rate that applies throughout the Commonwealth to make it 11.50 percent.
  • Indiana, Mississippi, Rhode Island and Tennessee have the second highest state sales tax rate at 7.00 percent.
  • Kodiak, Nome and Wrangell, all in Alaska, and Winter Park, CO have the highest city sales tax rate at 7.00 percent. Hoonah and Selawik, both in Alaska, have the second highest rate of 6.50 percent.
  • Tuba City (including the surrounding areas that are in the To’Nanees’Dizi Local Government), Coconino County, AZ has the highest combined sales tax rate of 12.90 percent.

The report highlights ever-changing and varying sales tax rates across jurisdictions. In the last 10 years in the U.S. there have been:

  • 2,319 new sales and use taxes, an average of 220 per year;
  • 4,095 sales and use tax changes, an average of 390 per year; and
