Who Must Register for Sales Tax in New Jersey?

Few questions cause more confusion for growing businesses than whether they have to register for sales tax in a particular state. In New Jersey, the answer depends on where you operate, what you sell, how much you sell into the state, and how you sell it. Getting it wrong in either direction costs money: collecting without a permit is a violation, and failing to collect when required leaves you owing the tax yourself.

New Jersey applies a single statewide sales tax rate of 6.625% with no local add-ons, and a reduced 3.3125% rate applies in designated Urban Enterprise Zones. Because the rate is simple, many owners assume compliance is simple too. The difficult part is knowing when your obligation begins, especially for online sellers who ship into the state without ever setting foot there.

This guide walks through every situation that creates a registration requirement in New Jersey, the thresholds for remote sellers, how marketplaces affect your obligations, how to register, and how to avoid the most common mistakes. Tax rules and thresholds change, so confirm current requirements with the NJ Division of Taxation or a qualified professional before you act.

1. Who Must Register: At a Glance

*General overview. Your specific facts, such as what you sell and how, determine your obligation, so confirm with the NJ Division of Taxation or a professional.

2. Businesses With a Physical Presence in NJ

If your business has any physical footprint in New Jersey and sells taxable goods or services, you must register before you start collecting tax. Physical presence is broader than many owners expect.

• Locations: a store, office, warehouse, or home-based business in the state
• People: employees, sales representatives, or contractors working in NJ on your behalf
• Property: inventory stored in the state, including stock held in a third-party fulfillment center
• Activity: installing, delivering, or servicing products inside NJ
• Events: selling at fairs, flea markets, or trade shows, which can require temporary registration

3. Remote Sellers and Economic Nexus

A business with no physical presence in New Jersey can still be required to register. Since November 1, 2018, a remote seller establishes economic nexus if, in the current or prior calendar year, it either:

• Has more than $100,000 in gross revenue from taxable sales delivered into New Jersey, or
• Makes 200 or more separate transactions delivered into New Jersey

Meeting either test triggers the requirement. Two details matter. First, the look-back covers the current and prior calendar year, so you can owe registration based on last year's volume. Second, a business with many small orders can reach 200 transactions long before it reaches $100,000.

4. Threshold Examples Chart

The chart below shows three illustrative remote sellers and how close each is to the two economic nexus tests. Bars are capped at the edge of the chart, and the label shows the actual share of each threshold.

*Illustrative examples only. Whether a sale counts toward the threshold depends on NJ rules, so confirm how your sales are measured.

5. Marketplace Sellers and Facilitators

Many sellers assume that selling on Amazon, Etsy, or eBay removes their sales tax obligations. It reduces them but does not always erase them.

• Marketplace facilitators are generally required to collect and remit NJ sales tax on sales made through their platforms
• Marketplace sales typically still count toward your economic nexus threshold
• A seller over the threshold that sells only through marketplaces must register but may be able to request non-reporting status for sales tax
• Sales through your own website or other direct channels are not covered by the marketplace's collection and still require you to collect
• The facilitators themselves can have registration duties once they meet the thresholds

6. Service Providers and What Is Taxable

Registration depends on whether what you sell is taxable. New Jersey taxes most retail sales of tangible goods, certain digital products and services, and specific service categories, while exempting others.

• Generally taxable: most tangible goods, prepared food, hotel occupancy, admissions, and certain services such as landscaping, janitorial, parking, and storage
• Commonly exempt: most clothing and footwear, many groceries, and prescription drugs, though exceptions exist for items like fur clothing and accessories
• Software and digital goods: treatment depends on the product and how it is delivered, so check the state's guidance
• Equipment purchases and leases: tax can apply to what your business buys or leases, which is covered in Should I Buy or Lease Equipment?

7. Who May Not Need to Collect

• Businesses that sell only non-taxable items and services
• Remote sellers below both economic nexus tests with no physical presence
• Sales made to buyers who provide a valid exemption certificate, such as a resale certificate, which you must keep on file
• Certain qualifying exempt organizations making qualifying sales, depending on the situation

Buying inventory for resale is a different question from selling it. If you track the cost of goods you buy for resale, see Cost of Goods Sold Calculation to keep your books accurate.

8. How to Register Step by Step

Remote sellers may also be able to use the multistate Streamlined Sales Tax registration system. Register before your first taxable sale, or as soon as you cross a threshold, rather than waiting until year-end.

9. What Happens After You Register

• You must file sales tax returns on your assigned schedule, which may be monthly, quarterly, or annual
• Returns are generally required even for periods with no sales
• Collected tax belongs to the state and should be kept separate from your operating cash
• You must keep sales records and exemption certificates for audits
• You must update the state when your address, ownership, or business structure changes

Our tax services in New Jersey cover registration, filing, and ongoing compliance.

10. Risks of Not Registering

• Back tax: you can owe the sales tax you should have collected, even if you never charged customers
• Penalties and interest: these accrue on unpaid tax and late filings
• Personal liability: in some cases the people responsible for the business can be held personally liable
• Audit exposure: state agencies increasingly use marketplace and payment data to find unregistered sellers
• Operational problems: collecting tax without a Certificate of Authority is itself a violation

11. Registration Checklist

• ☐ Determine whether you have physical presence in NJ, including inventory and workers
• ☐ Total your NJ sales and transactions for the current and prior calendar years
• ☐ Include marketplace sales when measuring thresholds
• ☐ Confirm which of your products and services are taxable
• ☐ Register and receive your Certificate of Authority before collecting
• ☐ Set up rates, exemption certificate collection, and a filing calendar
• ☐ Review nexus quarterly as your sales grow

12. Common Mistakes

• Assuming marketplaces handle everything and ignoring direct website sales
• Counting only dollars and missing the transaction test
• Ignoring the prior calendar year when checking thresholds
• Overlooking inventory in NJ warehouses as a physical presence
• Collecting tax before registering or waiting too long to register
• Forgetting zero-sales returns after registration
• Registering in NJ and assuming other states are covered, when each state has its own rules
