Sales Tax Filing Services NYC & NJ | OnPoint Business Tax & Accounting
NYC & NJ Sales Tax Filing Services
Accurate sales tax registration, filing, and compliance for NYC and NJ businesses. Flat-fee pricing. Never miss a deadline.
Sales tax compliance is one of the most error-prone areas for small businesses in New York and New Jersey. Rates vary by jurisdiction, product taxability rules are complex, and the penalties for late or incorrect filings add up fast. OnPoint handles registration, quarterly filings, and audit support so you stay compliant without the headache.
Whether you're a new business that needs to register for a sales tax certificate, an existing business that's fallen behind on filings, or a multi-location business navigating different rates across NYC boroughs and NJ counties — we handle it all at a flat fee.

Sales Tax Registration
We register your business for NYS, NYC, and NJ sales tax certificates so you're legally authorized to collect and remit.
Quarterly & Monthly Filings
