Serving Nassau County
Experienced Tax Preparation for Nassau County Residents & Business Owners
Nassau County is one of the most densely populated counties in the United States, with a large concentration of small business owners, self-employed professionals, and multi-income households. The tax situations we encounter here — rental properties on the south shore, W-2 plus side income, LLC and S-Corp filings, K-1s from partnerships — are among the most complex in the region.
Geiger Tax & Accounting is based in Amityville and has been serving Nassau County clients for over 30 years. We understand the financial landscape of this area — from the contractors and tradespeople in Farmingdale to the consultants and investors in Merrick — and we bring that local context to every return we prepare.
