NJ sales tax compliance services include registration with the NJ Division of Revenue, determining taxable vs. exempt transactions, filing NJ ST-50 returns, economic nexus analysis for remote sellers, and audit defense. Monaco CPA handles sales tax for NJ professional services firms, SaaS companies, e-commerce sellers, and retailers.

New Jersey's 6.625% sales tax applies to a wide range of transactions — but the rules on which services and digital products are taxable are genuinely confusing, even for experienced business owners. Getting it wrong can mean years of back taxes, interest, and penalties.

Monaco CPA helps NJ businesses determine whether they need to collect sales tax, register with the NJ Division of Revenue, file returns, and respond to audits. I work with professional services firms, SaaS companies, e-commerce sellers, retailers, and restaurants across New Jersey.

**Key NJ rule most businesses get wrong:** Professional services — accounting, legal, medical, consulting — are generally exempt from NJ sales tax. But information services, data processing, SaaS delivered electronically, and many digital products are taxable. If you're running a software business or a hybrid product-service business, the line matters significantly.

**Remote sellers:** After the Supreme Court's Wayfair decision, NJ requires out-of-state sellers to collect NJ sales tax once they exceed $100,000 in NJ sales or 200 separate transactions in NJ per year. If you're selling into NJ from another state, economic nexus rules may require registration.

How It Works

1

Nexus & Obligation Review

I review your business activities to determine whether you have a NJ sales tax collection obligation — and if you have any exposure from prior periods.

2

Registration & Setup

I file your NJ-REG registration with the NJ Division of Revenue and set up your filing schedule based on your expected sales volume.

3

Transaction Classification

I review your products and services to determine which are taxable, which are exempt, and how to document exemptions properly.

4

Filing & Ongoing Compliance

I prepare and file your NJ ST-50 returns on schedule and handle any correspondence or audit inquiries from the NJ Division of Taxation.

Frequently Asked Questions

Do I need to charge NJ sales tax on consulting services?
No — professional services such as accounting, legal, management consulting, and medical services are generally exempt from NJ sales tax under N.J.S.A. 54:32B. However, if your consulting work involves delivering a taxable information service, digital product, or software, the exemption may not apply. The line between a professional service and an information service is where most confusion (and audits) occur.
Is software taxable in NJ?
Generally yes. New Jersey taxes the sale of software delivered electronically, cloud-based software (SaaS), and digital products under N.J.S.A. 54:32B-8.56 and NJ Technical Advisory Memorandum 2013-10. This catches many small software businesses off guard. Prewritten software delivered on a physical medium, custom software, and certain B2B software transactions may have different treatment.
What is the NJ sales tax economic nexus threshold?
After the Wayfair decision, New Jersey enacted economic nexus rules: if you exceed $100,000 in NJ sales or 200 separate NJ transactions in the prior or current calendar year, you are required to register and collect NJ sales tax — even if you have no physical presence in NJ.
How often do I need to file NJ sales tax returns?
Filing frequency is set by the NJ Division of Revenue based on your expected sales volume. Businesses with less than $30,000 in annual NJ taxable sales typically file annually. $30,000–$500,000 file quarterly. Over $500,000 file monthly. The NJ ST-50 is the quarterly return form; monthly filers use NJ ST-51.
What happens if I haven't been collecting sales tax?
Exposure for uncollected NJ sales tax can be significant — the statute of limitations is generally 4 years, but it can extend if returns weren't filed. Voluntary disclosure through the NJ Division of Taxation can often reduce penalty exposure. I help businesses assess their exposure and navigate voluntary disclosure when appropriate.
Are NJ restaurant meals taxable?
Yes. Restaurant meals and prepared food are generally subject to NJ sales tax at 6.625%. Unprepared grocery food sold for home consumption is generally exempt. Catering services, alcoholic beverages, and delivery services have their own specific rules under N.J.S.A. 54:32B.
