Complete CPA Services for New York Businesses and Individuals
Our accounting services in New York cover everything your business or personal finances need, from day-to-day bookkeeping to long-range tax planning. Here's how we help.
Tax Services
New York's tax landscape trips up even careful taxpayers. Federal obligations, NYS income tax topping out at 10.9%, a separate NYC local tax layer, pass-through entity tax elections, and active NYS audit enforcement all demand year-round attention, not just a once-a-year filing.

Strategic, year-round planning built around your income, entity structure, and goals.
- Tax Preparation
Accurate preparation of individual, S-Corp, C-Corp, partnership, and LLC returns.

FAQs About CPA Services in New York State
Does New York have its own CPA licensing requirements separate from those of other states?
Yes. CPAs practicing in New York must be licensed through the New York State Education Department Office of the Professions and meet the requirements of the New York State Board for Public Accountancy. Rest assured that our firm meets all applicable standards.
What is New York's Pass-Through Entity Tax (PTET), and should my business elect it?
New York's PTET allows eligible S-Corps and partnerships to pay state income tax at the entity level, generating a federal deduction that can reduce the combined tax burden for owners. Whether the election benefits your situation depends on income, ownership structure, and federal position. It requires real modeling, and our team works through that analysis with clients regularly.
Do I need to file a New York return if I live in New Jersey but earn income in New York?
Yes. Non-residents who earn wages from work performed in New York, income from a New York business, or rental income from New York property must file a New York non-resident return (Form IT-203). Proper filing lets you claim the appropriate NJ credit for taxes paid to New York, avoiding double taxation on the same income.
What is New York's sales tax economic nexus threshold for online sellers?
Out-of-state sellers must register for New York sales tax once they exceed $500,000 in New York sales and 100 transactions in the prior four quarters. NY-based sellers must also navigate product-specific exemptions for food, clothing under $110, and certain services. The rules vary by category, and missing them generates assessments with interest and penalties.
Do you work with startups and new businesses in New York?
Yes. We love helping New York entrepreneurs structure their business correctly from the start: selecting the right entity, handling formation filings, setting up accounting systems, and building the financial foundation that supports early-stage growth and eventually attracts outside capital.
