Understanding Nexus Rules: When Do You Need to Register for Sales Tax?
What is Nexus?
Nexus is a legal concept that refers to a sufficient connection between a business and a state that requires the business to register and collect sales tax in that state.
Physical Nexus vs Economic Nexus
Physical Nexus
Physical nexus occurs when a business has a physical presence in a state, including:
- Employees: Hiring employees within the state
- Offices: Having offices or business locations in the state
- Warehouses: Storing inventory within the state
- Agents: Having sales representatives or agents in the state
- Trade Shows: Attending trade exhibitions or events in the state
Economic Nexus
Since the 2018 South Dakota v. Wayfair case, most states have implemented economic nexus rules:
- Sales Threshold: Annual sales exceeding a specific amount (typically $100,000-$500,000)
- Transaction Threshold: Annual transaction count exceeding a specific number (typically 200 transactions)
- Time Requirement: Usually requires meeting thresholds for 12 consecutive months
