Full-Service Accounting Services for Long Island Individuals and Businesses

One CPA Firm for Every Financial Function

Most of our clients came to us for one thing and stayed because we handle everything else, too. That's the difference between a full-service accounting firm and a tax-season-only preparer. Whether you're an individual filer, a small business owner, or a company that needs ongoing back-office support, the same CPAs who know your books are the ones reviewing your return.



CPA services in Nassau County and across Long Island tend to fragment quickly — one firm for taxes, another for books, a payroll company on top of that. When you work with Hirsch & Hirsch, those pieces are connected from the start.


Bookkeeping


Monthly reconciliation, cleanup for books that have fallen behind, and new business setup for owners starting from scratch. When your books are current all year, tax season stops being a scramble.

Payroll


We handle payroll processing, quarterly and annual tax filings, new employer setup, and payroll. Accurate, on time, and compliant with New York state and federal requirements.

Tax Preparation


We prepare individual, corporate, and partnership returns under CPA review. No hand-offs to someone who doesn't know your file. Your return is prepared by the same team that sees your full financial picture year round.

Tax Planning


Planning done in March doesn't help you for the year that just ended. We work with clients throughout the year to identify deductions, adjust withholding, and make decisions while there's still time to act on them.

Business Consulting 


Running a business means making financial decisions that go beyond what shows up on a tax return. We work with small business owners to make sense of what their numbers are actually saying.
