New York S-Corp Formation Guide for Physicians

New York S-Corporation Overview for Physicians

New York does not allow physicians to form standard Limited Liability Companies (LLCs) or corporations for the practice of medicine. Instead, New York requires physicians to form a Professional Limited Liability Company (PLLC) if they want limited liability protection while operating as an independent contractor. Once the PLLC is formed, it can elect S-Corporation tax treatment with the IRS, creating the same tax benefits available in other states but through a different entity structure.

The end result is functionally identical to an S-Corporation in other states. The physician receives limited liability protection, pass-through taxation, the ability to split income between W-2 salary and distributions, and access to retirement plan structures like Solo 401(k) and Cash Balance Plans. The difference is procedural. New York adds layers of complexity, longer timelines, higher costs, and unique ongoing requirements that do not exist in most other states.

Despite the added complexity, forming a PLLC with S-Corporation election remains the optimal structure for most New York physicians earning over $200,000 annually as independent contractors. The tax savings generated through reasonable compensation planning and retirement plan access far exceed the incremental cost and hassle of New York-specific requirements.

Why PLLC Is Required in New York

New York Education Law Article 145 governs the practice of medicine and establishes that physicians may only practice through specific entity types that maintain professional accountability and licensing oversight. A standard LLC or corporation does not meet New York's requirements for professional practice. Only a PLLC specifically authorized for medical practice is permitted.

Professional Service Restrictions

The core principle is that professional services requiring state licensure (medicine, law, accounting, architecture, engineering) cannot be rendered through ordinary business entities. New York views professional practice as requiring direct accountability to licensing boards. A PLLC maintains this accountability by requiring that all members hold the appropriate professional license and remain subject to professional discipline.

This means a New York physician cannot form a generic "John Smith Medical Consulting LLC" and practice medicine through it. The entity name must include "PLLC" or "Professional Limited Liability Company" and the Articles of Organization must specify that the purpose is the practice of medicine. The New York Department of State will reject any filing that attempts to use a standard LLC for medical practice.

Last updated: May 2026

Ownership and Membership Restrictions

All members (owners) of a PLLC formed for medical practice must be licensed physicians in good standing with the New York State Office of Professions. Non-physicians cannot own membership interests. This differs from some states where non-clinical personnel can hold minority ownership in physician practices. In New York, 100 percent physician ownership is mandatory for medical PLLCs.

Last updated: May 2026

For independent contractor physicians forming a single-member PLLC, this requirement is automatically satisfied. The physician is the sole member and holds the required license. Issues arise only when multiple physicians attempt to form a multi-member PLLC or when non-physician investors attempt to participate, which is prohibited.

PLLC vs. Professional Corporation

New York also permits physicians to form Professional Corporations (PCs). A PC is a corporation rather than an LLC, governed by different statutes, with different formation procedures and ongoing requirements. Most physicians prefer PLLCs over PCs because PLLCs offer simpler governance, no board of directors requirement, more flexible management structures, and easier dissolution if needed.

Last updated: May 2026

Both PLLCs and PCs can elect S-Corporation tax treatment. The choice between them is primarily about governance preference and administrative simplicity. For solo independent contractor physicians, the PLLC is almost universally the better choice.

Formation Timeline: 4 to 5 Months

New York PLLC formation takes significantly longer than LLC formation in other states due to the mandatory publication requirement. A realistic timeline from decision to fully operational status is 4 to 5 months. Physicians should plan accordingly and not expect to form a New York entity quickly.

Last updated: May 2026

The publication requirement is the bottleneck. It cannot be shortened, expedited, or avoided. Physicians planning mid-year S-Corporation election should begin the New York formation process at least 5 months before the desired effective date to ensure timely completion.

Publication Requirement Details

New York is one of only three states (New York, Arizona, Nebraska) requiring publication of LLC formation notices. The requirement exists to provide public notice of new business entities and dates back to 19th-century laws designed to combat fraud. It remains in effect despite widespread criticism as an outdated revenue generator for newspapers.

Which Newspapers and How to Find Them

The county clerk in the county where the PLLC's principal office is located designates which newspapers must be used. Each county maintains a list of approved newspapers. Typically this includes one daily newspaper and one weekly newspaper. The PLLC must publish in both.

Last updated: May 2026

To find the designated newspapers, contact the county clerk's office where your principal office is located. Many counties list approved newspapers on their websites. Some counties have only one or two approved newspaper combinations. Others (like Manhattan) have multiple options with widely varying costs.

Publication Cost by County

Publication costs vary dramatically by county. Manhattan (New York County) is notoriously expensive, with publication costs ranging from $1,200 to $1,800 for the required six-week run. Outer boroughs like Queens, Brooklyn, and the Bronx range from $800 to $1,200. Upstate counties (Albany, Buffalo, Rochester, Syracuse) typically cost $400 to $700. Rural counties can be as low as $300 to $500.

Last updated: May 2026

Some physicians attempt to reduce publication costs by listing a principal office address in a cheaper county. This strategy has risks. The Department of State can challenge whether the listed address is a legitimate principal office. If the physician never actually operates from that location, the filing could be deemed fraudulent. Conservative practice is to publish in the county where the physician actually maintains an office or conducts business.

What Happens If You Don't Publish

Failure to complete publication within 120 days of PLLC approval results in automatic suspension of the PLLC's authority to do business in New York. The entity technically still exists but cannot legally operate, sue, or enforce contracts. Banks may freeze accounts. Tax filings may be rejected. The physician would be operating without limited liability protection.

Last updated: May 2026

To cure a suspension, the physician must complete the publication requirement and file proof of publication along with a $50 fee. The suspension lifts once the filing is processed. However, any contracts signed or business conducted during the suspension period remains potentially voidable, creating legal risk.

Ongoing Compliance Requirements

Once formed, a New York PLLC with S-Corporation election has several ongoing compliance obligations at both state and federal levels.

Last updated: May 2026

New York State Tax Filings

Biennial Statement. Every two years, the PLLC must file a Biennial Statement with the Department of State confirming the entity's registered agent, principal office address, and current members. Filing fee is $9. Failure to file results in automatic dissolution of the PLLC after 18 months of delinquency.

New York Franchise Tax. New York imposes a franchise tax on S-Corporations doing business in New York. The tax is the greater of (1) a fixed dollar minimum tax based on New York source gross receipts, or (2) a calculated tax based on various measures including business income and capital. For most physician S-Corporations, the fixed dollar minimum applies, ranging from $25 to $4,500 annually depending on receipts. S-Corporations with New York receipts under $100,000 pay $25. Receipts of $1 million to $5 million trigger $1,500. Receipts above $25 million trigger $4,500.

New York S-Corporation Tax Return (Form CT-3-S). Due annually by March 15 (or the 15th day of the third month after the tax year ends for fiscal year filers). This return calculates the franchise tax and reports the PLLC's New York source income.

Last updated: May 2026

Estimated Tax Payments. If the franchise tax exceeds $1,000, quarterly estimated payments are required. These are due in four installments throughout the year similar to federal estimated payments.

Last updated: May 2026

Personal Income Tax Obligations

The physician must file a New York resident income tax return (Form IT-201) reporting all income including the S-Corporation pass-through income. New York does not have separate S-Corporation shareholder reporting like some states. The K-1 from the S-Corporation flows directly to the personal return.

Last updated: May 2026

If the physician works in multiple states, multi-state tax filing obligations arise as discussed in the Multi-State Taxation guide. New York source income is taxed by New York. Income earned in other states is taxed by those states, with New York providing a credit for taxes paid elsewhere.

Last updated: May 2026

Federal Filings

The S-Corporation files Form 1120-S with the IRS annually reporting income, deductions, and shareholder distributions. The physician receives a Schedule K-1 showing the pass-through income that flows to their personal Form 1040. Quarterly payroll tax filings (Form 941) are required if the physician takes W-2 salary, which is almost always the case for S-Corporation structures.

Last updated: May 2026

Professional Licensing and Renewals

The physician's individual medical license must remain current and in good standing. New York requires triennial license renewal with continuing medical education requirements. Separate from individual licensing, the PLLC itself does not require professional licensing, but the physician members do.

Cost Breakdown for New York PLLC Formation

Total costs to form a New York PLLC and elect S-Corporation status typically range from $1,500 to $3,500 depending on county, whether professional assistance is used, and whether expedited processing is chosen.

Last updated: May 2026

Minimum cost for a DIY formation in a low-cost upstate county is approximately $550 to $750 (filing fees plus publication). Typical cost with professional assistance in a mid-cost county (Albany, Rochester, Syracuse) is $1,500 to $2,000. Manhattan formation with attorney assistance runs $2,500 to $3,500.

Last updated: May 2026

Ongoing annual costs include the biennial statement ($9 every two years), franchise tax ($25 to $1,500+ depending on receipts), and CPA fees for tax preparation ($1,500 to $3,500 annually for combined business and personal returns).

Multi-State Considerations for New York Physicians

Many New York physicians work across state lines, creating multi-state tax and compliance obligations. The New York PLLC structure adds complexity to these situations.

Last updated: May 2026

Working in New Jersey, Connecticut, or Pennsylvania

Tri-state area physicians frequently work in multiple states. A New York PLLC performing services in New Jersey, Connecticut, or Pennsylvania typically does not need to register as a foreign entity in those states unless the PLLC maintains a physical office, has employees, or otherwise establishes substantial nexus there.

Last updated: May 2026

However, the physician personally will owe non-resident income tax returns to each state where income is earned. A New York physician working locum shifts in New Jersey must file a New Jersey non-resident return (NJ-1040NR) reporting New Jersey source income. New York taxes all income but provides a credit for taxes paid to New Jersey.

Last updated: May 2026

The New York PLLC files its S-Corporation returns in New York only. The individual physician handles multi-state personal income tax filings based on where services were physically performed.

Last updated: May 2026

The Statutory Residency Trap

New York has aggressive statutory residency rules. A person who maintains a permanent place of abode in New York and spends more than 183 days in New York during the tax year becomes a New York statutory resident subject to tax on worldwide income, even if domiciled elsewhere.

Last updated: May 2026

This creates problems for physicians who live in New Jersey or Connecticut but work frequently in New York. If they maintain an apartment in New York for convenience and exceed 183 days in New York, they accidentally trigger statutory residency. Careful day tracking and avoiding permanent New York lodging is essential.

Last updated: May 2026

Foreign Entity Registration in Other States

If the New York PLLC establishes a physical presence in another state (opens an office, hires employees, owns property), foreign entity registration in that state may become required. Each state has different thresholds for triggering foreign entity registration.

Last updated: May 2026

For most independent contractor physicians, this is not an issue. The physician personally performs services in other states under contract, but the PLLC itself does not operate there. As long as the PLLC's activities in other states are limited to the physician's personal service provision without establishing physical presence, foreign registration is typically not required.
