S-Corp vs. LLC vs. C-Corp: Which Structure Saves the Most Tax in New York?

Choosing the wrong business structure costs New York owners thousands every year, not in penalties, but in taxes they never had to pay. 

I’ve worked with S-Corp owners in Manhattan and across the Tri-State Area for 28 years. The question I hear most often from growing LLCs and new businesses is the same: which structure actually saves me the most? The answer is not one-size-fits-all, but the math is clearer than most people think. 

This blog breaks down how each structure is taxed, shows you a side-by-side New York example with real numbers, and gives you a decision framework based on where your income falls. No theory. Just the numbers you need to decide. 

How Is an LLC Taxed in New York vs. an S-Corp vs. a C-Corp? 

An LLC taxed as a sole proprietor pays self-employment tax on every dollar of profit. An S-Corp splits income between a salary and distributions; only the salary is subject to payroll tax. A C-Corp pays a flat 21% federal corporate tax, then shareholders pay again on dividends. 

That summary covers the core difference. But in New York, the picture has two layers: federal tax and state tax. Both matter. 

NYC-specific note: LLCs, partnerships, and sole proprietors operating in New York City may be subject to the 4% Unincorporated Business Tax. Federal S corporations generally are not subject to UBT, but NYC does not recognize S-Corp treatment the same way New York State does and may subject S corporations to the General Corporation Tax. This should be modeled before choosing a structure. 

How Much Tax Does Each Structure Actually Save? A Real New York Example 

At $150,000 in net business profit, a New York S-Corp owner saves approximately $8,000 to $11,000 per year in payroll taxes compared to a single-member LLC, after accounting for S-Corp compliance costs. 

Here is what the numbers look like for a Manhattan-based consultant earning $150,000 in net profit in 2026: 

*Estimates based on 2026 federal rates (32% bracket), NY state income tax (~7.65% effective), and 2026 Social Security wage base of $184,500. Individual results vary. Consult a CPA before electing. 

At What Income Level Does an S-Corp Election Start Making Sense in New York? 

An S-Corp election generally makes financial sense when net business profit exceeds $40,000 to $50,000 annually, which is the point where payroll tax savings start to outweigh the added compliance costs of running payroll and filing Form 1120-S. 

Here is a quick income-based decision guide for New York business owners: 

To elect S-Corp status, you file IRS Form 2553 within 75 days of forming your entity, or by March 15 for the election to take effect in the current tax year. New York State does not always automatically follow the federal S-Corp election. In many cases, shareholders must file Form CT-6 to be treated as a New York S corporation, and the entity will file Form CT-3-S annually. For a deeper break-even analysis, see our guide on whether you should convert your LLC to an S-Corp in New York. 

When Does a C-Corp Make Sense for a New York Business Owner? 

A C-Corp makes sense primarily when you plan to raise venture capital, issue multiple classes of stock, or retain significant profits inside the business at a tax rate lower than your personal rate. For most NY small business owners, it does not. 

The C-Corp’s 21% flat federal rate looks attractive at first glance. But when you distribute that profit to yourself as a dividend, you pay personal income tax on top, currently 15% to 23.8% federally, plus New York State. That double taxation typically erases the corporate tax advantage for owner-operated businesses. 

In my experience at Colella CPA, the only New York small business owners who benefit from C-Corp status are those who:  

(1) plan to seek venture funding, 
(2) have investors who require it, or 
(3) are retaining large profits inside the business for reinvestment and do not need to draw them out.  

Everyone else pays more, not less, over time. 

What Are the New York-Specific Tax Rules That Change This Decision? 

New York does not always follow federal tax treatment, and these differences can shift the structure calculus, particularly for NYC-based businesses, which face an additional layer of city tax. 

Key New York and NYC differences to know: 

• NYC Unincorporated Business Tax (UBT): LLCs and partnerships operating in New York City pay a 4% UBT on net income above $95,000. SS-Corps are generally not subject to UBT, but NYC corporate tax rules may still apply, so the comparison should be modeled carefully..
• NY Bonus Depreciation Non-Conformity: New York State does not follow federal 100% bonus depreciation rules (restored by the OBBBA, effective January 19, 2025). Equipment purchases fully deducted federally must be depreciated over a longer schedule at the state level.
• Pass-Through Entity Tax (PTET): New York’s PTET election allows S-Corps and partnerships to pay state income tax at the entity level, generating a federal deduction that individual owners cannot otherwise claim. This is one of the most significant NY-specific planning tools available in 2026.
• NY S-Corp Filing: Form CT-3-S: New York does not always automatically follow the federal S-Corp election. In many cases, shareholders must file Form CT-6, and the entity files Form CT-3-S annually. The state minimum tax for S-Corps starts at $25 and scales with NY-source gross income. 

Common Mistakes New York Business Owners Make When Choosing a Structure 

• Staying as a sole proprietor past $50,000 in profit: Every year you delay an S-Corp election at this income level costs you $3,000–$7,000 in unnecessary self-employment tax.
• Choosing a C-Corp for tax savings without modeling distributions: The 21% rate looks good until you add dividend tax. Most owners end up paying more in total.
• Ignoring the NYC UBT: Manhattan and outer-borough business owners who overlook the 4% UBT underestimate their actual LLC tax burden by a material amount.
• Not electing PTET as an S-Corp:  New York’s Pass-Through Entity Tax election is one of the most valuable federal deductions available to Tri-State business owners in 2026. Many S-Corps miss it entirely.
• Setting an S-Corp salary arbitrarily: The IRS requires shareholder-employees who perform services to receive reasonable compensation before taking distributions, and underpaying salary is a common audit risk.

Which Structure Should You Choose? A Simple Decision Framework 

Use this to identify your starting point. A CPA review is still required before any election. 

1. Net profit under $40,000: Stay as a single-member LLC. S-Corp compliance costs will exceed savings.
2. Net profit $40,000–$80,000: Model both options. S-Corp may be worth it depending on your industry, salary requirements, and whether you operate in NYC.
3. Net profit above $80,000: S-Corp election is almost always the right answer. File Form 2553 before March 15 for same-year effect.
4. Seeking outside investment or issuing stock options: C-Corp (Delaware or NY). This is the only scenario where C-Corp wins for most small businesses.
5. Operating in New York City: Factor in the 4% UBT when comparing LLC to S-Corp. The gap between structures is wider in NYC than anywhere else in the state.
6. Already an S-Corp earning above $250,000: Review your reasonable salary annually. Also model the PTET election, as it is likely worth taking in New York.

Conclusion 

For most New York small business owners, the right structure depends on profit, payroll, growth plans, and NYC tax exposure. LLCs work well at lower income levels, S-Corps often save more as profits rise, and C-Corps usually fit investor-backed businesses. 

The key is not to choose based on general advice. Run the numbers before making an election. At Colella CPA, our tax planning and strategy services help New York business owners compare LLC, S-Corp, and C-Corp tax outcomes, so they can choose a structure that supports both tax savings and long-term growth.
