Choosing the right business structure is one of the most important financial decisions a business owner can make. Many owners focus on “tax savings,” but entity selection is not just about reducing tax. Each structure comes with different rules, risks, compliance burdens, and long-term consequences.
Most business owners do not choose the wrong entity because they are careless. They choose it because no one explained how the IRS actually evaluates business income. The IRS does not reward entity selection alone—it evaluates whether the way income is classified matches the reality of how the business operates.
At IVY Tax & Business Inc. (安腾会计), we help clients understand how these structures work so they can make informed, compliant decisions based on business activity, reporting obligations, and long-term strategy.
Who This Is For
This guide is designed for:
- Small business owners in New York
- LLC members and partnership owners
- S-Corporation shareholders
- Real estate investors using LLCs or partnerships
- Clients located in Long Island and NYC
Understanding the Three Entity Types
LLC (Limited Liability Company)
An LLC is a flexible legal structure. For federal tax purposes, it is typically treated as:
- A sole proprietorship (single-member LLC), or
- A partnership (multi-member LLC)
Key Characteristics:
- Pass-through taxation
- Profits reported on the owner’s personal tax return
- Flexible allocation of income among partners
- Active business income is generally subject to self-employment tax, while certain passive income, such as rental income, may not be
S Corporation
An S Corporation is not a distinct type of legal entity — it is a federal tax election made with the IRS via Form 2553, filed under Subchapter S of the Internal Revenue Code. The underlying legal entity — typically a corporation, or in some cases an LLC — remains a fully separate legal entity with its own liability protections. What the S-Corp election changes is how that entity is taxed, not its legal structure. An S Corporation is a pass-through entity, meaning its income, deductions, and tax attributes flow through to the shareholders’ individual tax returns.
Key Characteristics:
- Pass-through taxation — income flows to shareholders’ personal returns
- Owners may receive both salary and distributions
- Potential reduction in self-employment tax exposure, provided reasonable compensation is properly established and documented under IRS standards
- More compliance requirements, including payroll, filings, and corporate formalities
C Corporation
A C Corporation is a separate legal and tax entity incorporated under state law. It files its own tax return, pays its own corporate-level tax, and is legally distinct from its shareholders.
Key Characteristics:
- Pays its own corporate tax
- Shareholders are taxed separately on dividends
- Greater flexibility for reinvestment and scaling
- Often used for larger or growth-oriented businesses
A C Corporation may be useful where profits are expected to remain in the business, but excessive retention of earnings without a clear business purpose may trigger accumulated earnings tax under IRS rules.
High-Level Entity Comparison
| Feature | LLC (Default) | S Corporation | C Corporation |
| Taxation | Pass-through | Pass-through | Entity-level tax |
| Self-employment / payroll tax | Often applies to active income | Generally applies to salary only | Not applicable in same way |
| Profit distribution flexibility | High | Moderate | Low (formal dividends) |
| Complexity | Low to moderate | Moderate to high | High |
| Best fit | Simplicity, real estate, flexible ownership | Active operating businesses | Scaling, reinvestment, outside growth |
Where Tax Differences Actually Come From
LLC: Simplicity Over Optimization
An LLC is often the cleanest and simplest structure. It provides liability protection and flexible tax treatment, but it does not automatically create tax savings.
For active operating businesses, income is often exposed to self-employment tax. For passive activities, such as many rental arrangements, that treatment may differ. This is why LLCs are often used for:
- Real estate holding structures
- Multi-owner businesses needing flexibility
- Businesses prioritizing simplicity over payroll planning
The benefit of an LLC is usually simplicity and flexibility, not aggressive tax reduction.
S Corporation: Payroll vs. Distribution Strategy
S Corporations may create tax efficiency by dividing business income into:
- Reasonable compensation, which is subject to payroll tax
- Distributions, which are generally not subject to self-employment tax
This is where many owners focus on “savings,” but this is also one of the IRS’s most heavily reviewed areas. The tax benefit does not come from forming an S-Corp by itself. It comes from how compensation is established and whether it is defensible.
This structure requires:
- Ongoing payroll compliance
- Careful documentation
- Consistent reporting
- A salary that reflects IRS reasonable compensation standards
An S-Corp with an artificially low salary may reduce payroll taxes in the short term, but it also increases audit risk and possible reclassification.
C Corporation: Deferral and Reinvestment
C Corporations may offer advantages when profits are retained in the business rather than distributed.
Potential benefits include:
- Deferral of shareholder-level tax while profits remain inside the company
- Structured reinvestment into growth
- Clear separation between business and personal taxation
However, double taxation may apply when profits are distributed as dividends. Also, keeping too much cash in the corporation without a documented business reason may create accumulated earnings tax exposure.
The C-Corp advantage is often about timing and reinvestment, not elimination of tax.
Simple Numerical Example
A basic example helps show where the difference may occur. Assume a business generates $300,000 of profit before owner compensation.
If taxed as an LLC
If the income is active business income, a substantial portion may be exposed to self-employment tax, in addition to income tax.
If taxed as an S Corporation
If the owner takes:
- $120,000 as salary — that portion is subject to payroll taxes
- The remaining profit may be distributed, subject to income tax but generally not self-employment tax
This may create payroll tax savings, but only if the salary is reasonable and properly documented.
If taxed as a C Corporation
The corporation pays tax at the corporate level. If profits are retained and reinvested, shareholder-level tax may be deferred. If profits are later distributed, dividend taxation applies.
This is why the right structure depends less on the label and more on:
- How the owner is paid
- Whether profits are distributed or retained
- Whether the business can support the compliance burden
IRS Perspective
From the IRS perspective, entity choice does not create automatic savings. The IRS evaluates whether:
- Compensation is reasonable
- Distributions are properly characterized
- Retained earnings have a real business purpose
- Passive and active income are being correctly classified
In other words, the IRS is not impressed by the entity itself. It looks at whether the tax treatment matches the actual business activity.
New York–Specific Considerations
New York adds additional layers that often influence entity selection.
For LLCs and Partnerships
- Subject to New York filing requirements and annual fees
- Income allocated based on New York-source income rules
- Multi-state considerations may apply
For S Corporations
- New York State imposes a fixed minimum tax on S-Corps
- New York City does not recognize S-Corporation status and generally taxes S-Corps at the entity level under General Corporation Tax rules — creating a risk of double taxation for NYC-based shareholders
- Additional compliance and reporting obligations apply
| Critical NY-Specific Rule: A federal S-Corp election (Form 2553) does NOT automatically apply to New York State. Businesses must file a separate New York S-Corp election using Form CT-6 with the NYS Department of Taxation and Finance. Failing to file CT-6 means the entity will be taxed as a C corporation at the state level, even if it is treated as an S corporation federally. |
For C Corporations
- Subject to New York corporate franchise tax
- NYC corporate tax may apply if operating in the city
- Separate state and city filings are generally required
Real Estate Considerations
For real estate investors in New York:
Key Points
- Rental income is generally considered New York-source income if the property is located in New York
- LLCs and partnerships must file informational returns
- Ownership structure affects reporting and tax treatment, but not the local property tax itself
Important Distinction
- Property tax is based on the property
- Income tax depends on how the activity is structured and reported
This is one reason real estate owners often prefer LLCs: the structure is usually chosen for liability protection, ownership flexibility, and pass-through reporting rather than payroll-tax strategy.
Common Mistakes and Risks
Some of the most common entity-related mistakes include:
| Mistake | Description |
| S-Corp with artificially low salary | Choosing S-Corp without payroll readiness; salary too low relative to profit |
| LLC with active income | Assuming LLC income is automatically exempt from self-employment tax |
| NYC S-Corp oversight | Ignoring NYC’s General Corporation Tax — S-Corp status is not recognized by the City |
| Missing NYS CT-6 filing | Assuming federal S-Corp election automatically applies to New York State |
| C-Corp with no reinvestment plan | Retaining earnings without a documented business purpose; may trigger accumulated earnings tax |
These mistakes are not just technical. They can lead to audits, notices, penalties, and a structure that becomes expensive to fix later.
The Biggest Mistake We See
The most common mistake is not choosing the wrong entity on paper. It is choosing a structure without understanding why the tax result happens.
Examples include:
- An S-Corp owner taking a $20,000 salary on $300,000 of profit
- A C-Corp retaining profits year after year without a documented business purpose
- An LLC owner assuming there is no self-employment tax risk simply because the entity is an LLC
- An S-Corp owner assuming their federal election automatically covers New York State — without filing Form CT-6
Most entity problems begin when owners focus on the outcome they want, instead of the IRS rules that support that outcome.
How IVY Tax & Business Inc. Supports Clients
We work with clients to evaluate entity structure based on:
- Business activity and growth plans
- Income patterns and reinvestment goals
- New York State and NYC tax exposure
- Long-term compliance and reporting needs
- Whether the structure is operationally sustainable, not just tax-efficient on paper
Our approach focuses on clarity, compliance, and practical planning rather than short-term tax positioning.
Conclusion
There is no single “best” entity for tax savings. An LLC offers simplicity. An S-Corp may create payroll-tax efficiency if compensation is properly handled. A C-Corp may help with reinvestment and timing, but not without trade-offs.
The real question is not which entity sounds better. It is which structure aligns with how the business actually earns, pays, distributes, and retains income.
Careful planning—especially in New York—is essential to balance tax efficiency with compliance, audit defensibility, and long-term sustainability.
