Sales tax nexus

What is Sales Tax Nexus?

Sales tax nexus refers to the specific connection or presence a business has within a state or jurisdiction, that necessitates collecting and remitting sales tax. Essentially, it represents whether your company has a significant enough presence within a territory that requires tax compliance.

Historically, nexus was straightforward, focusing primarily on physical presence—offices, warehouses, retail outlets, or employees located within a state. However, since the landmark Supreme Court ruling in the case of "South Dakota v. Wayfair, Inc." in 2018, nexus rules expanded significantly. Many states enacted economic nexus rules, basing sales tax obligations on sales volume and transaction count rather than physical presence alone.

Today, even businesses operating solely online must carefully track their sales data. For many retailers, hitting certain revenue or transaction thresholds in a specific state triggers tax nexus. This obligates them to register, collect, and remit sales taxes, impacting their administrative processes and compliance responsibilities.

Determining your sales tax nexus is critical: failure to comply with relevant state tax rules has financial and legal consequences. Businesses are encouraged to regularly audit their nexus status, aligning their tax management practices with current nexus standards.

What exactly is sales tax nexus?

Sales tax nexus refers to a business's connection or presence within a state or jurisdiction that requires them to collect and remit sales tax. It means the business has sufficient presence in a territory, either physically or economically, to be obligated for sales tax compliance.

Did the Supreme Court decision in South Dakota v. Wayfair impact nexus rules?

Yes, the 2018 Supreme Court decision in the South Dakota v. Wayfair case significantly expanded nexus rules. It introduced economic nexus, where states can require sales tax collection based on sales volume or transaction count, even without physical presence.

What triggers economic nexus for online businesses?

Economic nexus is typically triggered by online sellers reaching specific sales revenue thresholds or number of transactions in a state. Once these criteria are met, sellers are required to register, collect, and remit sales taxes to that state.
