Our focus is simple:
Your accounting must be accurate, predictable, and ready for anything the city throws at you — whether it’s a filing, an audit, or a lender request.

NYC-Specific Accounting and Tax Issues

Unincorporated Business Tax (UBT)

Service businesses, contractors, consultants, and freelancers often owe UBT without realizing it. We calculate exposure, apply available deductions, and ensure filings are accurate.

Sales Tax Requirements

Restaurants, retailers, e-commerce sellers with NYC nexus, and service businesses with taxable work must file correctly and on time. We handle registrations, filings, reconciliations, and audit preparation.

Aggressive City and State Audits

New York audits frequently and expects clean documentation. We prepare your books, manage correspondence, and represent you with NYC and NYS.

Employee Payroll Compliance

NYC has strict withholding, wage, and reporting requirements. We make sure payroll is accurate for local and remote teams.

Entity Structure Considerations

NYC businesses often benefit from restructuring when income increases. We handle S-Corp analysis, partnership reviews, and multi-entity setups.

Industry-Specific Rules

Restaurants, medical practices, real estate investors, and tech firms each face different compliance demands. We tailor systems to your industry’s real requirements.
