Understanding Nexus in New Jersey
In New Jersey, your obligation to collect and remit sales tax is determined by “nexus,” which refers to the connection between your business and the state. There are two primary types of nexus: physical and economic.
Physical Nexus
- Physical nexus is established when your business has a tangible presence in New Jersey. This includes:
- Operating a store, office, or warehouse in the state
- Having employees, agents, or representatives working in New Jersey
- Storing inventory within the state
- Conducting sales or service activities in New Jersey
- If your business engages in any of these activities, you must register for a New Jersey sales tax permit and collect sales tax on taxable sales within the state.
Economic Nexus
- Economic nexus applies to businesses that do not have a physical presence in New Jersey but have significant sales in the state. As of November 1, 2018, a remote seller must register, collect, and remit New Jersey sales tax if, during the current or prior calendar year, they:
- Have gross revenue exceeding $100,000 from sales of tangible personal property, specified digital products or taxable services delivered into New Jerse or
- Conduct 200 or more separate transactions of such sales in New Jersey
- These thresholds include both taxable and nontaxable retail sales.
Marketplace Facilitators
- If you sell through a marketplace facilitator (e.g., Amazon, Etsy), the facilitator is responsible for collecting and remitting sales tax on your behalf for sales made through their platform. However, if you also directly sell to New Jersey customers outside these platforms, you may have your tax obligations.
- Understanding your nexus status is crucial for compliance. GTA Accounting Group can help assess your business activities to determine if you have a nexus in New Jersey and guide you through the necessary steps to meet your tax obligations.
