Start Your Business on the Right Foot

Starting up involves choices that affect taxes, liability, and flexibility for years. As your business startup accountant, we translate the rules into plain English, help you avoid common pitfalls, and map a clear path from idea to open-for-business in Port Jefferson and across Long Island.

Choose the Right Entity—LLC, S-Corp, C-Corp, or Partnership

Entity choice drives tax treatment, payroll needs, and how profits are paid out. We provide entity selection advice in NY tailored to your goals and expected income—so you understand tradeoffs before you file.

Registration & Compliance—Handled Correctly from Day One


We manage the paperwork and keep you organized. Expect a clear timeline and status updates as we obtain your EIN, register with New York State, and set up sales tax and payroll accounts where needed. If your business sells taxable goods or hires employees, we’ll ensure the right IDs and portals are in place.



We’ll also help you understand local requirements in areas like Port Jefferson Village and Smithtown—so permits, DBAs, and certificates don’t slow your opening week.

Set Up Your Books the Smart Way


Good habits early save rework later. As your LLC setup consultant on Long Island, we’ll configure QuickBooks (Online or Desktop) with a tailored chart of accounts, bank feeds, receipt capture, classes/locations, and simple monthly close tasks. You’ll get starter training plus a one-page “how we book things” guide for your team.



Need projections for a landlord or conversation with a lender? We can help build a practical startup budget and 12-month cash plan (we don’t broker loans). When you’re ready, add payroll, sales tax filings, and monthly bookkeeping for a true one-team workflow.

Ongoing Support as You Grow

We don’t disappear after the paperwork. Count on us for business tax preparation and planning, bookkeeping, payroll, and practical advisory check-ins—so your numbers stay clean and your decisions stay grounded. If you’re moving from a side-gig in Nesconset to a storefront in St. James, we’ll adjust your entity, taxes, and systems as you scale.
