LLC vs S-Corp: Which Is Right for Your Business?

What Is an LLC?

A limited liability company (LLC) is a business structure that provides personal liability protection for its owners (called members) without the formality requirements of a corporation. LLCs are formed under state law by filing Articles of Organization with the state.

By default, a single-member LLC is taxed as a sole proprietorship (disregarded entity), and a multi-member LLC is taxed as a partnership. Both options mean all profits flow through to the owner's personal tax return — this is called pass-through taxation.

LLCs are the most popular business structure in the U.S. because they offer flexibility, liability protection, and minimal administrative requirements.

What Is an S-Corp?

An S-Corp is a tax election, not a business entity type. It stands for Subchapter S corporation, referring to Subchapter S of the Internal Revenue Code. You can have either a regular corporation (C-Corp) or an LLC elect S-Corp tax status by filing IRS Form 2553.

When a business elects S-Corp status, it's still taxed as a pass-through entity (profits flow to owners' personal returns), but there's a key difference: the owner can divide income between a W-2 salary and distributions. Only the salary portion is subject to self-employment taxes.

The S-Corp election is primarily a tax strategy, not a structural change.

LLC vs S-Corp: Key Differences

Tax Comparison

LLC default taxation:

As a sole proprietor or partner (default for LLCs), you pay self-employment (SE) tax on your entire net profit. In 2026, SE tax is 15.3% on the first $176,100 of net earnings and 2.9% on amounts above that. This is on top of income tax.

Example: LLC with $150,000 net profit.

• SE tax: ~$21,195
• Federal income tax (assuming 22% bracket): ~$33,000
• Total tax burden: ~$54,195

S-Corp taxation:

With S-Corp status, you split income between a W-2 salary (subject to payroll taxes) and distributions (not subject to SE/payroll taxes). Payroll taxes only apply to the salary portion.

Same example: $150,000 profit, $80,000 salary, $70,000 distribution.

• Payroll taxes on $80,000 salary: ~$12,240 (split between employer/employee)
• Federal income tax on full $150,000: ~$33,000
• Total tax burden: ~$45,240

Estimated savings: ~$9,000/year — but there are costs: payroll processing, additional accounting, and state-level S-Corp fees reduce the net benefit.

The S-Corp election typically starts making financial sense when net profits exceed $40,000–$60,000 per year. Below that threshold, the administrative costs often exceed the tax savings.

The S-Corp Salary Requirement

The IRS requires S-Corp owner-employees who provide services to the business to pay themselves a "reasonable salary" before taking distributions. This is the critical compliance requirement of S-Corp status.

"Reasonable salary" means what you would pay someone else to do your job. The IRS scrutinizes cases where owners take low or zero salaries to avoid payroll taxes. If audited, the IRS can reclassify distributions as wages and assess back payroll taxes plus penalties.

Determining your reasonable salary:

• Research what comparable positions pay in your industry and location
• Consider your experience, hours worked, and responsibilities
• Document your reasoning in case of audit

There is no official IRS formula, but a common rule of thumb is to allocate 50–60% of your S-Corp income as salary and take the remainder as distributions — while staying defensible as "reasonable" for your specific role.

Ownership and Investor Restrictions

This is where LLCs have a significant structural advantage.

S-Corp restrictions:

• Maximum 100 shareholders
• All shareholders must be U.S. citizens or permanent residents
• Only one class of stock permitted (can't have preferred vs. common shares)
• Cannot be owned by other corporations, partnerships, or most trusts

LLC flexibility:

• No cap on the number of members
• Foreign nationals can be members
• Multiple classes of membership interests (preferred returns, different voting rights)
• Can be owned by other entities

If you plan to raise venture capital, bring in foreign investors, issue preferred shares, or build a complex ownership structure, an LLC is nearly always the right choice. S-Corp status is incompatible with most venture capital structures.

Administrative Requirements

LLC administration:

• Annual report or statement of information filed with the state (varies by state)
• Operating agreement (recommended but not legally required in most states)
• Separate business bank account
• Basic recordkeeping

S-Corp administration:

• All LLC requirements, plus:
• Quarterly payroll tax deposits (Forms 941)
• Annual W-2 and W-3 filings for owner-employees
• Annual federal S-Corp return (Form 1120-S)
• Schedule K-1 for each shareholder
• Corporate minutes and resolutions for significant decisions

S-Corp status adds meaningful payroll and accounting overhead. Budget for a payroll service ($50–$150/month) and a CPA who understands S-Corp compliance.

When an LLC Makes More Sense

Choose a standard LLC when:

• You're early stage. Until you're generating consistent profit above ~$60,000/year, the complexity of S-Corp status isn't worth it.
• You want investment flexibility. Raising capital from VCs, angels, or foreign investors requires an LLC (or C-Corp — not S-Corp).
• You want simplicity. One less set of compliance requirements, no payroll for yourself, simpler tax filing.
• You're in a real estate or investment business. LLCs are almost universally preferred for holding real estate or investment assets.
• You have operating losses. Pass-through losses from an LLC can offset your other income directly.

---

When an S-Corp Makes More Sense

Consider S-Corp election when:

• Consistent net profits exceed $60,000–$80,000/year. At this level, self-employment tax savings materially exceed compliance costs.
• You're a service business with few employees. Consulting, law, accounting, and similar businesses are classic S-Corp candidates.
• You don't need investor flexibility. If you're bootstrapped and profitable, S-Corp restrictions don't limit you.
• Your state has favorable S-Corp treatment. Some states follow federal S-Corp tax treatment; others impose their own entity-level taxes (see below).

---

The LLC Taxed as S-Corp Strategy

You don't have to choose between "be an LLC" and "be an S-Corp." You can have both: form an LLC, then elect S-Corp tax treatment by filing IRS Form 2553 with the IRS within 75 days of formation (or by March 15 of the tax year).

This is the most common structure for profitable small businesses:

• LLC for legal protection and structural flexibility
• S-Corp tax treatment for self-employment tax savings

The entity is still an LLC under state law. You get the liability protection and operational flexibility of an LLC, with the tax efficiency of an S-Corp.

State-Specific Considerations

Not all states honor S-Corp elections or treat them the same way as the IRS:

California: Imposes an 1.5% franchise tax on S-Corp income (minimum $800/year), plus the standard LLC fee. California is one of the most expensive states for both entity types. See California business guides →

New York: Recognizes S-Corps but imposes a fixed-dollar minimum tax based on receipts. New York City has its own Unincorporated Business Tax for LLCs. See New York business guides →

Texas: No state income tax, so the S-Corp payroll tax savings are the same as the federal level. Texas has a franchise tax (Margin Tax) that applies to most entities. See Texas business guides →

Florida: No state income tax, favorable for both structures. Florida does not impose an additional tax on S-Corps. See Florida business guides →

Frequently Asked Questions

Can I switch from LLC to S-Corp later? Yes. You can elect S-Corp status for an existing LLC by filing Form 2553. The election must be made by March 15 to take effect for the current tax year, or within 75 days of formation for a new entity.

Does an S-Corp protect me from personal liability? Yes. S-Corp status doesn't change your liability protection — you still have the same protection against personal liability for business debts that you'd have as an LLC or corporation.

Do I need a separate EIN for an S-Corp election? If your LLC already has an EIN, you use the same one after electing S-Corp status. No new EIN is needed.

What happens to my S-Corp election if I bring in a foreign investor? The S-Corp election is automatically terminated if you add a non-resident alien as a shareholder. Plan ahead — if investment is in your future, stay with default LLC taxation or convert to a C-Corp.

Is an S-Corp better than a C-Corp? For most small businesses, yes. C-Corps face corporate-level tax (21% federal in 2026) plus individual tax on dividends — creating double taxation. S-Corps avoid this with pass-through treatment. C-Corps make sense primarily for businesses seeking venture capital or planning to go public.
