A record year for U.S. sales tax rate changes

How to Conduct a Reverse Sales Tax Audit

U.S. sales tax rate changes reached a 10-year high in 2023 – that’s one of many compelling findings from Vertex’s 2023 Year-End Sales Tax Rates and Rules report. The research I’m citing here runs through Nov. 30, where the total number of 2023 sales tax rate changes across all jurisdictions reached 437 (state, county, city and district). 

Above all, Vertex’s Sales Tax Rates and Rules provides tangible proof of the complexity that indirect tax teams have been challenged with over the past few years. Besides the record number of rate changes, tax groups are also contending with hefty amounts of new taxes at the city and district level. That rules-and-rate volatility is what I currently find most noteworthy from our year-end data. Here are a few other highlights to provide an early look at the sales tax research based on data collected by our own Vertex Tax Research Team: 

  • A 10-year high for combined rate changes: The previous record-high number of combined rate changes (412) occurred in 2017. In 2022, we saw 377 rate changes. In 2023, 437 sales tax rate changes marks a 16% increase over last year’s combined rate changes.  
  • District rate changes also escalate: As I’ve mentioned before, roughly 100-plus new district taxes are enacted each year to fund fire protection, emergency services, hospitals and the like. As all of these new district taxes continue to accumulate, more and more tax jurisdictions are recalibrating their tax rates. The number of district-level tax changes increased more than threefold from 2022 (52 rate changes) to 2023 (169 rate changes). Fortunately for taxpayers, the vast majority of this year’s district tax rate changes consisted of rate decreases (mainly due to the prohibition of 128 municipalities in Alabama from collecting license revenue, taxes or fees in their respective police jurisdictions). However, the opposite is true among city and county jurisdictions.  
  • Tax rate increases dominate in cities and counties: Of the 75 sales tax rate changes that took place at the county level, 52 were rate increases and only 23 consisted of decreases (a nearly 2:1 ratio). At the city level, sales tax rate increases (158) outnumbered decreases (33) by almost 5:1.   
  • States continue to issue new fees, exemptions and tax holidays: State and local jurisdictions continue to implement more fees, including green fees, retail delivery service fees, and fees on transactions within airport and entertainment/dining districts. As I’ve noted, these fees are not sales and use taxes per se, but they pose similar challenges and complexities to indirect tax teams. In 2023, several states implemented new green fees (including Maryland and Pennsylvania), new sales tax exemptions or updates to existing exemptions (Ohio, Tennessee, and Florida), and new delivery fees (Minnesota).  

I’ll keep you up to date on the final year-end data, along with a rundown of sales tax trends in an upcoming post.
