More Than Filing Paperwork
As a startup formation attorney serving Long Island, Shari guides entrepreneurs through every legal decision of launching a company as part of the firm's business law practice. Filing with the state is the easy part. Choosing between an LLC, corporation, or partnership has tax and liability consequences that follow you for years, and the ownership documents behind that choice decide what happens when partners disagree, when you want to sell, and when you eventually step away.
Mistakes made at the beginning turn into expensive problems later. The wrong entity means an avoidable tax bill or personal exposure to business debts. A skipped operating agreement means New York's default rules run your company instead of you.
We also coordinate with your accountant from day one. Entity selection is where legal and tax strategy overlap, and the structure your accountant recommends only protects you once the legal documents make it real. If your accountant told you to form an LLC or elect S Corp status, we're the ones who draft and file it properly.
And because the firm handles business succession planning too, your formation gets built with the exit in mind. The entity and ownership terms you pick on day one shape what selling, handing off, or bringing in partners looks like decades later. When the day comes, the attorney who formed the company already knows every document in the file.
Which Entity Fits Your Business?
Compare the structures most Long Island businesses choose between. Pick one to see how it works.
Limited Liability Company
The workhorse for Long Island small businesses
Personal assets are shielded from business debts and lawsuits when the LLC is run properly.
Pass-through by default: profits land on your personal return with no corporate-level tax. Can elect S Corp treatment later as income grows.
Articles of Organization, New York's publication requirement, and a written operating agreement, which NY law requires LLCs to adopt.
Contractors, professional services, real estate holdings, and most owner-operated businesses that want protection without corporate formality.
S Corporation
A tax election that can cut self-employment taxes
Same personal protection as a corporation or LLC that elects S status.
Pass-through, with the ability to split income between salary and distributions, which can lower self-employment tax once profits justify it.
Corporate or LLC formation plus an IRS election, payroll requirements, and ownership limits: 100 shareholders max, one class of stock, U.S. owners only.
Profitable owner-operated businesses where the tax savings outweigh the added payroll and compliance work. This is the election accountants most often recommend, and we paper it correctly.
C Corporation
Built for outside investment and stock
Full separation between the corporation and its shareholders.
The corporation pays its own tax, and dividends are taxed again personally. That double layer is the price of flexibility on ownership.
Certificate of Incorporation, bylaws, shareholder agreements, board records, and annual formalities that must be kept up.
Companies planning to raise investment, issue stock options, or take on shareholders an S Corp can't accept.
Partnership / Sole Proprietorship
The default you fall into by not choosing
None. You and the business are legally the same, so business debts and lawsuits reach your house, your savings, and your family's assets.
Pass-through, with self-employment tax on everything.
Almost none, which is exactly why so many Long Island businesses are still running this way years after they should have formed an entity.
Very early testing of an idea. Once there's revenue, a lease, an employee, or a partner, the lack of protection costs more than an LLC ever would.
This comparison is general information, not legal advice for your situation. The right structure depends on your ownership, income, and plans, which is exactly what the free consultation sorts out.
Forming in New York Has Its Own Rules
Online formation services file the same generic documents in all fifty states. New York isn't generic. The state requires LLCs to adopt a written operating agreement, layers on its own tax elections and fees, and enforces a publication requirement that most do-it-yourself founders discover only when a bank or a buyer asks for their Certificate of Publication.
We handle the whole sequence: preparing and filing the formation documents, drafting an operating agreement that matches how your business will actually run, coordinating the publication with the county clerk's designated newspapers, and getting your EIN and elections in place so the company is fully compliant before the first invoice goes out.
Then the relationship keeps working. The same office that formed your company drafts your client contracts and vendor agreements, and stands behind them in commercial litigation if it ever comes to that.
The NY LLC Publication Requirement
Within 120 days of formation, New York LLCs must publish a notice in two newspapers designated by the county clerk for six consecutive weeks, then file a Certificate of Publication with the state.
Skip it, and the state can suspend your LLC's authority to do business in New York.
Local advantage: publication costs are set by county newspaper rates, and publishing from a Suffolk County address like Deer Park runs a fraction of what New York City filers pay.

Built on Solid Ground, Explained in Plain Language
Starting a business should be exciting, not overwhelming. Shari has been forming Long Island companies since 2006, and every founder gets the same treatment: quick responses, plain-language explanations, and a legal foundation that supports growth instead of getting in its way.
You also get a firm that's still here after the filing. The businesses we form come back for their leases, their contracts, their disputes, and eventually their succession plans, because the attorney who set up the company already knows how it runs.
"Shari was wonderful to work with and helped me with everything I needed. She was able to resolve any issues very quickly. Highly recommend."

You can file paperwork on your own, but the filing is the easy part. A lawyer makes sure your entity choice, operating agreement, and ownership terms actually protect you, which is where do-it-yourself formations usually fall short.
An LLC offers flexibility and simpler pass-through taxes, which fits most Long Island small businesses. A corporation may be better for raising investment or issuing stock. The right answer depends on your ownership, your tax situation, and your exit plans.
New York requires new LLCs to publish a notice in two newspapers for six consecutive weeks within 120 days of formation, then file a Certificate of Publication. Skipping it can suspend your LLC's authority to do business in the state. Costs vary by county, and publishing from a Suffolk County address is far less expensive than from New York City.
Most filings can be completed within a few weeks, depending on state processing times. Expedited processing is available when you need the entity formed quickly for a deal or a lease.
Yes. We draft the operating agreement, client contracts, and partnership agreements that protect your company from disputes, so the legal foundation is done once and done right.
Filing the Paperwork Is Easy. Filing It Right Is the Point.
An online service will form something. A formation attorney forms the right thing, with the agreements behind it that keep partners, taxes, and New York State from becoming problems later.
