Who must register for New Jersey sales tax
You must register for a New Jersey Certificate of Authority if your business has a sales tax nexus in the state. This usually applies when a business:
- Exceeds the economic nexus threshold of $100,000 in annual sales or 200 or more separate transactions into New Jersey in the current or previous calendar year, or;
- Has a physical presence in New Jersey, such as an office, employee, warehouse, or inventory stored in the state.
New Jersey meets the standard economic nexus threshold used by most states — either the dollar amount or the transaction count, whichever you reach first.
Once you exceed the threshold, you should register before making further taxable sales in New Jersey. If you're unsure whether your business has nexus, see the New Jersey Sales Tax Guide for a broader explanation of New Jersey nexus rules.
Note: New Jersey is one of the few states where SaaS is generally not taxable under Technical Bulletin TB-72. If you sell only SaaS to New Jersey customers, confirm your taxability situation before registering.
