Choosing the right business structure is one of the most important decisions for an entrepreneur. While both a Limited Liability Company (LLC) and an S Corporation (S Corp) offer liability protection and pass-through taxation, they differ substantially in ownership rules, formalities, tax-structuring opportunities and operational flexibility. Understanding these differences — and how they apply to your unique business situation — will save you time, money and stress as your company grows.
Key Takeaways
Both LLCs and S Corps offer limited liability protection and pass-through taxation, but they differ in ownership rules, management formalities, tax mechanics and flexibility.
LLCs are generally simpler and more flexible, making them a strong choice for many small business owners starting out.
S Corp status is a tax election, not a separate entity type; it can offer self-employment tax savings, but comes with more administrative burden and stricter rules.
If your business is profitable and stable, and you’re ready for the added complexity, electing S Corp treatment may yield meaningful tax savings.
Don’t overlook state-specific laws, compliance requirements, and your long-term growth plans; consulting a professional before filing is highly recommended.

Determining the type of legal structure for a new business can be daunting for entrepreneurs and small business owners. Corporations and limited liability companies (“LLCs”) are preferred business structures because, unlike sole proprietorships and partnerships, both offer liability protection. This means that the owner of a company cannot be held personally responsible for the company’s debts. The personal assets of an owner are shielded from company liabilities.
In researching the various business structures, one inevitably comes across the S corporation. S corps and LLCs are similar in that they are both “pass-through” entities for tax purposes; the income of these companies are passed through to their owners and reported on the owners’ personal income tax returns, thereby eliminating the double taxation incurred by owners of a standard corporation, or C corporation. (With a C corporation, the net business income is subject to corporate income tax, and the monies remaining after the corporate income tax are taxed a second time when they are distributed as dividends to its owners, who must then pay personal income tax.)

So, what is the difference between an S corporation vs. LLC? Which structure is right for you?
The answer depends on your unique situation. If operational ease and flexibility are important to you, an LLC is a good choice. If you want to save on employment tax and your situation warrants it, an S corporation could work for you.
Business Ownership & Operation
There are restrictions on who can be owners (called “shareholders”) of an S corporation. An S corporation can have no more than 75 shareholders. None of the shareholders can be nonresident aliens. And shareholders cannot be other corporations or LLCs.
An S corporation is operated in the same way as a traditional C corp. An S corp. must follow the same formalities and record-keeping procedures. The directors or officers of an S corp. manage the company. An S corporation has no flexibility in splitting profits amongst its owners. The profits must be distributed according to the ratio of stock ownership, even if the owners may otherwise feel it is more equitable to distribute the profits differently.
LLCs offer greater flexibility in ownership and ease of operation. There are no restrictions on the ownership of an LLC. An LLC is simpler to operate because it is not subject to the formalities by which S corps must abide. An LLC can be member-managed, meaning that the owners run the company, or it can be manager-managed, with responsibility delegated to managers who may or may not be owners in the LLC. And an LLC’s owners can distribute profits as they see fit.
Let’s say, for example, you and a partner own an LLC. Your partner contributed $40,000 for capital. You only contributed $10,000, but you performed 90% of the work. The two of you decide that, in the interest of fairness, you will each share the profits 50/50. As an LLC, you could do that; with an S corporation, however, you could only take 20% of the profits while your partner would take the other 80%.
Table 1. LLC vs. S Corp: Ownership and Management Compared
LLC
S Corporation
Unlimited number of members (owners) in most states; members may be individuals, corporations, other LLCs, foreign persons/entities.
Must first be a domestic corporation (or in some cases an LLC that elects S status) and must file IRS Form 2553 to be taxed as an S Corp
Flexible management: member-managed (owners run the business) or manager-managed (owners appoint managers).
Ownership restrictions: fewer shareholders (ex. many sources say up to 100) and all must generally be U.S. citizens or resident aliens; cannot be non-resident alien individuals, and certain entities (e.g., corporations, partnerships) may not be shareholders.
Profit (and loss) allocations can often be done in ways other than strictly proportional to ownership, depending on your operating agreement.
Corporate formalities: must follow corporate governance rules (board, officers, formal meetings, record-keeping) in many states.
Fewer formalities: no required board, fewer mandated meetings/minutes (depending on state).
Profit distributions must conform to ownership (i.e., you cannot easily allocate 70% to one owner and 30% to another if ownership is 50/50) unless special stock classes are allowed (though S Corps must generally have only one class of stock).

Employment Tax: Savings vs. Paperwork
A key motivation for many business owners is tax savings. How you’re taxed — and how much employment or self-employment tax you incur — can differ substantially.
LLC (default treatment)
By default, a single-member LLC is taxed as a sole proprietorship (disregarded entity) and a multi-member LLC as a partnership, meaning practically all net business income flows through to members and is subject to self‐employment tax (i.e., Social Security + Medicare) on the owner portion.
Paperwork & tax filings tend to be simpler; you report via your individual tax return (Schedule C for sole‐member, Form 1065 for multi-member) rather than separate corporate tax filings.
S Corporation
The entity is taxed as a pass-through (so no double taxation like a C Corporation), but: the owner/shareholder who also works in the business must be paid a “reasonable salary” (W-2 wages) which are subject to employment taxes (FICA etc). The remaining profit distributions (beyond salary) are not subject to self-employment tax.
This structure can yield savings: you avoid paying self-employment tax on the full profit, only on the salary portion. However, the salary must be considered “reasonable” in the eyes of the IRS, and you must comply with payroll taxes, withholdings, filing, and other formalities.
Because of the extra administrative burden (payroll, corporate tax return for the S Corp, stricter record-keeping), the tax savings may not always justify the cost, especially for very small businesses or those with unpredictable cash flow.
A major factor differentiating an S corporation from an LLC is the employment tax paid on earnings. The owner of an LLC is considered to be self-employed and, as such, must pay a “self-employment tax” of 15.3%, which goes toward Social Security and Medicare. The entire net income of the business is subject to self-employment tax.*
In an S corporation, only the salary paid to the employee-owner is subject to employment tax. The remaining income that is paid as a distribution is not subject to employment tax under IRS rules. Therefore, there is the potential to realize substantial employment tax savings.
Case in point:
Mary owns a print shop. In keeping with the industry standard, Mary decides that a reasonable salary for a print shop manager is $35,000 and pays herself accordingly. Mary’s total earnings for the year are $60,000: $35,000 paid in salary, and the remaining $25,000 paid as a distribution from the S Corp. Mary’s total employment tax is $5,355 (15.3% of $35,000).
If Mary were the owner of an LLC, she would have to pay employment tax on the entire $60,000, equaling $9,180. But as an S corporation, she realizes $3,825 in employment tax savings.
One might assume that these savings could be further manipulated by reducing the salary to an extremely low amount and attributing the rest of one’s earnings to distributions — but this would be an incorrect assumption. In practice, the IRS carefully notices whether a salary is reasonable by industry standards. If it determines a salary to be unreasonable, the IRS will not hesitate to reclassify distributions as salary.
Still, while the potential employment tax savings may make the S corporation an attractive structure for your business, bear in mind that you would then have to deal with all the paperwork associated with payroll tax. The payroll tax is a pay-as-you-go tax that must be paid to the IRS regularly throughout the year–on time, or you will incur interest and penalties. The paperwork alone can be an overwhelming task for someone who is not familiar with this; and if you expect to incur losses or otherwise experience a cash flow crunch during the year that would hinder you from paying the payroll tax when due, this could present a problem.
LLC owners pay their self-employment tax once a year on April 15, when income taxes are normally due. Income tax filings are also relatively easy for the owners of an LLC: A single-member LLC files the same 1040 tax return and Schedule C as a sole proprietor; partners in an LLC file the same 1065 partnership tax return as do owners of traditional partnerships.
The comparison chart below sums up the similarities and differences between the two business structures:
Comparison Overview: S Corporation vs LLC
S Corporation (S Corp)
Limited Liability Company (LLC)
Liability Protection
Yes
Yes
Operational Control
Board of Directors/ Officers
May be member-managed or manager-managed
Federal Income Tax
Pass-through when S election made; requires salary + distributions
Default pass-through; can elect corporate tax
Flexibility/Ease of Operation
No; subject to some formalities and record keeping rules as traditional C corps
Yes
Ownership Flexibility
More restricted: limit on number/shareholder type
High: unlimited members, non-residents allowed
Management Flexibility
More formal: board/officers, corporate structure
Very flexible: members or managers
Profit/ loss allocation flexibility
Limited: distributions must align with stock ownership
Owner-employees pay employment tax on salary only; distributions not subject to SE tax
Owners often pay SE tax on full net income
Which Structure Is Right for You?
There is no one “best” entity for all businesses. The optimal structure depends on your individual situation: your expected profits, number of owners, growth plans, investor requirements, willingness to handle formalities, cash flow consistency, and tax-planning goals.
Choose an LLC (or remain as one) if you:
Are starting smaller or expect modest profits initially
Want maximum flexibility in management and profit allocation
Wish to minimize upfront administrative burden and cost
Have non-U.S. owners or plan to involve other entities as owners
Want a structure that allows you to transition later with ease
Choose or convert to an S Corporation (or have your LLC taxed as an S Corp) if you:
Expect significant net profits where employment tax savings may justify the extra formalities
Are comfortable maintaining payroll, withholding, W-2s and corporate filings
Have U.S. resident owners and fewer ownership restrictions
Want to raise capital or signal credibility (corporate formality can help)
Have stable cash flow, predictable income, and the ability to pay yourself a “reasonable salary”
Tip: Many small business owners form an LLC and then elect S Corp tax status (via IRS Form 2553) when their profits reach a threshold that makes the tax savings outweigh the extra cost/complexity.
Final Thoughts
Choosing the right business structure is a decision you’ll live with for many years — so it’s worth taking time, consulting with your CPA or tax attorney, and revisiting your structure as your business grows or changes. The wrong choice can cost you in taxes, missed opportunities, or headaches down the road.
Remember: there is no one magical entity that works for everyone. A CPA or a specialized tax attorney can assist you in choosing the right structure for your business. It is important to consider each structure’s operational, legal, and tax aspects as they apply to your unique situation.
* For the tax year 2025, the self-employment tax rate remains at 15.3%. This rate comprises two parts: 12.4% for Social Security and 2.9% for Medicare. It’s essential to keep this updated tax rate in mind when considering your business structure and tax obligations.
For 2025, the first $168,600 of your combined wages, tips, and net earnings are subject to any combination of the Social Security part of self-employment tax, Social Security tax, or railroad retirement (tier 1) tax. (Source: IRS)
*For those who prefer the tax treatment of an S corp but like the simplicity of an LLC, there is an alternative worth considering: Forming an LLC that is taxed as an S corp. An LLC may make a special election with the IRS to be taxed as an S corp. This election is made on IRS Form 2553 and must be filed with the IRS before the 16th day of the third month of the tax year in which the election is to take effect.
An LLC that is taxed as an S corp is still a limited liability company from a legal standpoint (subject to the laws governing limited liability companies in the state of formation); however, for tax purposes it is treated as an S corp.
A word of caution: Certain nuances of S corp taxation can be confusing to some LLC owners, especially do-it-yourselfers and/or those who prepare their own tax returns; for example, an LLC owner might easily make the mistake of referring to an IRS publication that addresses LLCs when, in fact, such a publication would not apply to an LLC that is taxed as an S corp–and such an error could lead to negative tax consequences. It is therefore highly recommended that you consult a CPA or other qualified tax professional for advice and/or assistance.
Frequently Asked Questions (FAQs)
What is the difference between an LLC and an S Corporation?
In short: an LLC is a legal entity formed under state law, while an S Corporation is a federal tax election that some eligible entities (LLCs or corporations) can make. An LLC provides flexibility in management and profit distribution; an S Corp imposes more formalities (corporate governance structure) but offers certain tax advantages by enabling owner-employees to split compensation between salary (subject to employment tax) and profit distributions (not subject to self-employment tax).
Can an LLC become an S Corporation?
Yes. If an LLC meets the eligibility requirements for S Corporation tax status (including IRS deadlines), it can file IRS Form 2553 to elect to be taxed as an S Corp. This means legally it remains an LLC (under state law) but for federal tax purposes it is treated like an S Corp.
What kinds of rules or restrictions apply to S Corporations that don’t apply to LLCs?
Key restrictions include: a limit on the number of shareholders (commonly cited as 100) and the requirement that shareholders be U.S. citizens or resident aliens. S Corps also must generally have only one class of stock, follow corporate formalities (board, meetings, minutes), and cannot allocate profits in ways that deviate from ownership interest. LLCs have more flexibility on owners, types of owners, distributions, and management structure.
How do taxes differ for an LLC versus an S Corporation?
With a default LLC, the business income passes through to the members, and typically all net income is subject to self-employment tax (Social Security + Medicare). With an S Corp, the owner-employee receives a salary (subject to payroll/employment taxes) and the remaining profit flows through to shareholders as distributions, which are generally not subject to self-employment tax. But to benefit, the salary must be “reasonable” and the business must handle payroll, withholding, filings, etc.
When does it make sense to switch from an LLC to an S Corporation election?
Switching (or electing S status as an LLC) often makes sense when profits have grown enough that the tax savings from reduced self-employment tax outweigh the additional costs (payroll, corporate filings, record-keeping). However, you should consider: whether your business has consistent profits, whether you have the infrastructure for payroll and compliance, whether you meet S Corp eligibility, and whether you’re comfortable with the more formal structure. Consulting with your CPA or tax advisor is key to evaluate if/when the change is worthwhile.
