Long Island

Long Island Small Business Accounting

Tax preparation, advisory, and accounting for small business owners and the self-employed across Nassau and Suffolk County — from someone who has done this work on Long Island for decades.

Local, by design

An accountant who knows Long Island business

Running a business on Long Island comes with its own realities — New York State and local filing rules, the cost of doing business here, and the mix of trades, professionals, freelancers, and family companies that make up the local economy. Geiger Tax & Accounting has worked with that mix for over 30 years, from a base in Amityville and across Nassau and Suffolk County.

The advantage of a local practice is not the address — it is the judgment. We have seen how these businesses actually operate, where owners get tripped up, and what the state and the IRS look for. That context is the difference between a return that just gets filed and one that reflects decisions made with intent all year.

What you get

A practice built around owners, not volume

We work the way a small business owner needs an accountant to work:

A real person who knows your file and answers year-round — not a seasonal call center
Tax preparation and planning handled together, so the return informs next year
Straight talk on entity structure, payroll, and what is worth doing — and what is not
A secure TaxDome portal so documents move easily whether you are local or remote
Practitioner-to-practitioner judgment, in plain language, without the upsell

We keep the practice deliberately sized so clients get attention, not a ticket number.

Where we serve

Across Nassau and Suffolk County

We serve owners throughout Long Island — across Nassau County communities like Massapequa, Wantagh, Merrick, Bellmore, Seaford, Farmingdale, and Amityville, and through Suffolk County in Babylon, Lindenhurst, Huntington, Islip, Bay Shore, and the surrounding areas. Many clients work with us entirely through the secure portal, so where you sit on the Island is rarely a constraint.

We also work with business owners in New York City and remotely nationwide — but Long Island is home, and it is where most of our clients are.
