How to Start an S Corp in New York (State and NYC Rules)

What You Need to Know About S Corps in New York

An S Corp is a tax classification, not a business structure. In New York, you form a regular C corporation first, then elect S status for federal tax purposes and separately for New York State. This two-step process is crucial because New York State has its own S election requirements independent of federal rules, and New York City imposes an additional tax on S corporations that most business owners don't expect.

Unlike sole proprietorships or partnerships, an S Corp provides liability protection while allowing income to pass through to owners without double taxation. However, the setup process is more complex in New York than in many other states, and the tax benefits depend on careful compliance with both federal and state requirements.

This guide covers the exact steps to form an S Corp in New York, the fees involved, processing timelines, and the critical tax rules that differ between New York State and New York City.

S Corp vs. LLC in New York: Which Is Right for You?

New York business owners often compare S Corps to LLCs because both offer pass-through taxation and liability protection. The key difference is structural: an LLC is a business entity recognized by New York law, while an S Corp is a tax designation applied to a corporation.

An S Corp election makes sense if you are a business owner paying yourself a salary from your business and want to minimize self-employment taxes. To qualify, you must be a U.S. citizen or resident alien, have no more than 100 shareholders, and have only one class of stock. S Corp owners pay themselves a "reasonable salary" subject to payroll taxes, then take remaining profit as a distribution, which avoids self-employment tax.

An LLC is simpler to set up and maintain but does not automatically reduce self-employment taxes. If you are a solo operator or partnership without the income level to justify the extra compliance burden, an LLC often makes more sense. If you have multiple co-owners or expect significant profits, an S Corp election can save substantial money on taxes despite higher administrative costs.

In New York specifically, LLC and S Corp formation fees are different. A New York LLC costs $200 to file Articles of Organization, while a New York corporation costs $125 to file the Certificate of Incorporation. Both must file biennial statements (every two years) for $9 each. The real cost difference emerges in payroll processing and tax compliance after formation.

Step 1: Form a New York Corporation

To elect S status, you must first form a regular C corporation under New York law. You cannot form an S Corp directly; the S designation is a tax election applied to an existing corporation.

To form a New York corporation, file a Certificate of Incorporation with the New York Department of State, Division of Corporations, State Records and Uniform Commercial Code. The filing fee is $125. You can file online through the New York Business Express system at https://www.businessexpress.ny.gov/ or submit a paper form by mail.

Your Certificate of Incorporation must include your corporation's name (which must end in "Corporation," "Inc.," "Co.," or similar indicator), the number of shares the corporation is authorized to issue, the county where the principal place of business is located, and the address where the Department of State can serve legal documents. Processing through the online system typically takes the same business day; mailed filings take longer.

The filing fee of $125 is not negotiable, but expedited processing is available: $25 for 24-hour processing, $75 for same-day processing, and $150 for processing within 2 hours. These expedited fees are in addition to the base $125 filing fee.

After the corporation is formed, you will receive a Certificate of Incorporation. You do not need a registered agent in New York (the Secretary of State serves as the statutory agent for service of process), but you do need to designate an address where legal documents can be delivered, and you should obtain an employer identification number (EIN) from the Internal Revenue Service.

Step 2: File Form CT-6 for New York S Election

This is the step most New York business owners overlook, and it is critical. In addition to the federal S Corp election, New York State requires a separate S election using Form CT-6 (Election by a Small Business Corporation to be Taxed as an S Corporation for New York Purposes).

Form CT-6 must be filed with the New York Department of Taxation and Finance. Unlike the federal Form 2553 (discussed below), Form CT-6 is not filed with the IRS; it is a New York State-specific requirement.

You must file Form CT-6 at any time during the tax year before the year the election is to take effect, or by the 15th day of the third month of the tax year it is to take effect. If you miss the deadline, the state may reject your S status for New York tax purposes even if the federal election is valid. Consult the Department of Taxation and Finance website at https://www.tax.ny.gov/ for the current CT-6 form and submission instructions.

Filing Form CT-6 does not cost extra but is mandatory for your S Corp election to be recognized in New York. This is a compliance step that cannot be skipped.

Step 3: File Form 2553 for Federal S Election

After forming your New York corporation, file Form 2553 (Election by a Small Business Corporation) with the Internal Revenue Service to elect federal S Corp status. The form must be signed by a corporate officer and all shareholders and filed with the IRS no more than 2 months and 15 days after the beginning of the tax year the election is to take effect, or at any time during the preceding tax year.

Form 2553 is free to file but must be submitted to the IRS at the address specified on the form (this changes periodically, so verify the current address on the IRS website). There is no filing fee to the federal government.

The timing of your S election matters for tax purposes. If you file Form 2553 too late, the IRS may disallow the election for that year, meaning your corporation will be taxed as a C corporation and subject to double taxation. It is critical to file this form promptly and keep documentation of when it was filed.

New York State Tax Rules for S Corporations

New York State does not tax a New York S corporation's income at the Article 9-A business income rates that apply to C corporations. Instead, the S corporation files Form CT-3-S and pays the Article 9-A fixed dollar minimum tax, while the income passes through to shareholders.

Additionally, New York assesses a fixed dollar minimum tax scaled to your New York receipts. For S corporations this minimum ranges from $25 for New York receipts of $100,000 or less to $4,500 for receipts over $25 million. Even if your corporation has no profit, you must pay the minimum tax. This is a significant difference from federal S Corp treatment and catches many business owners by surprise.

S corporation income is also passed through to shareholders, who report their share of income on their personal tax returns. New York has a progressive personal income tax with rates ranging from 4% to 10.9% depending on income level, plus an additional local tax if you live in New York City or Yonkers. This pass-through structure is why an S election can save money on self-employment taxes, because distributions taken from the corporation are not subject to the 15.3% self-employment tax paid by sole proprietors and partnerships.

New York City S Corporation Tax: The Surprise

Here is the critical fact many New York City S Corp owners learn too late: New York City does not recognize S Corp status for tax purposes. If your S corporation is based in New York City, the city still treats it as a regular corporation and imposes its General Corporation Tax at a flat rate of 8.85% on your business income.

This means an S corporation headquartered in New York City pays the New York State fixed dollar minimum tax and also the New York City 8.85% General Corporation Tax. The S election eliminates federal double taxation but does not eliminate New York City's separate tax.

Outside New York City, the state corporate franchise tax applies. This is a major difference between doing business in the five boroughs and elsewhere in New York State. An S Corp formed in Buffalo, Syracuse, or any non-NYC location avoids the 8.85% city tax.

The 8.85% NYC General Corporation Tax applies to the corporation's entire net income regardless of how that income is distributed. Combined with the state and federal taxes, this can be a substantial burden. Before electing S status for a New York City business, calculate the total tax cost and compare it against the self-employment tax savings. You may find that an LLC or C corporation is more advantageous depending on your business structure and income level.

Timeline and Costs

Here is what you can expect for time and money to start an S Corp in New York:

The Certificate of Incorporation filing fee is $125 (online processing typically same business day). The biennial statement fee will be $9 every two years. Form CT-6 and Form 2553 have no direct state or federal filing fees but must be filed on time to be valid.

Total startup cost for the formation and tax elections is approximately $125 to $150 in government fees, assuming you file the forms yourself. If you hire an attorney or formation service, expect $300 to $1,000 additional. The ongoing annual and biennial compliance costs include the $9 biennial statement (due every two years during the month the corporation was originally filed), plus payroll processing, accounting, and tax preparation costs that scale with your business size.

The timeline: Filing the Certificate of Incorporation online takes one business day. Form CT-6 has its own deadline: file it during the preceding tax year or by the 15th day of the third month of the tax year the election is to take effect. Form 2553 must be filed within 2 months and 15 days after the start of the tax year the election is to take effect.

Annual Compliance and Reporting

After forming your S Corp, you must file annual payroll taxes, corporate income tax returns, and biennial statements. S corporations in New York must file Form CT-3-S (Corporation Tax Return for Small Business Corporations Electing to be Taxed Under Section 1362 of the Internal Revenue Code) with the New York Department of Taxation and Finance. This return is due by the 15th day of the third month after the close of your tax year.

You must also file Form 1120-S with the federal IRS at the same time. Shareholders receive Schedule K-1 forms reporting their share of income and must file personal income tax returns reporting this income.

Every two years, file the Biennial Statement with the Department of State during the month your Certificate of Incorporation was originally filed. The fee is $9.

Maintain corporate bylaws, a corporate records book, and documentation of shareholder meetings and major decisions. Proper records are essential for liability protection and tax compliance. Failure to maintain corporate formalities can result in "piercing the corporate veil," meaning courts may hold owners personally liable for business debts.

When to Consult a Tax Professional

This guide is informational only and does not constitute legal or tax advice. The rules for S corporations in New York are complex, particularly the interplay between federal, state, and New York City taxes. Before electing S status, consult a certified public accountant (CPA) or tax attorney who understands New York State and New York City business taxes.

A professional can model the tax impact of an S election for your specific business structure and income level, verify that you meet the requirements, and ensure all forms are filed correctly and on time. The cost of a consultation (typically $200 to $500) can easily pay for itself through tax savings or by preventing costly mistakes.

You should also consult an attorney if your business is multi-member, if you have significant assets, or if you plan to add shareholders or raise capital. An S Corp is a specific election with strict requirements, and the wrong structure can undo the tax benefits you are trying to achieve.
