LLC vs S Corp vs C Corp 2026: Which Structure Saves You the Most?

Your business structure determines how much tax you pay, how exposed your personal assets are, and whether investors will fund you. The wrong choice costs thousands per year. The right one can legally cut your self-employment tax bill by thousands.

Here is the honest comparison.

The Core Difference: How You Get Taxed

LLC: Pass-Through Simplicity

A single-member LLC is a "disregarded entity" — all profit flows to your personal return on Schedule C. You pay income tax plus 15.3% self-employment tax on every dollar of profit.

Example: $100,000 profit = $15,300 in self-employment tax alone, before income tax.

S Corp: The Salary Split

An S Corp is not a separate entity — it is a tax election. You form an LLC or corporation, then file Form 2553 to be taxed as an S Corp. The magic: you pay yourself a reasonable salary (subject to payroll tax) and take the rest as distributions (not subject to self-employment tax).

Example: $100,000 profit, $60,000 reasonable salary:

• Payroll tax on salary: ~$9,180
• Distribution of $40,000: $0 self-employment tax
• Savings vs LLC: ~$6,120/year

C Corp: Double Taxation, But VC-Ready

A C Corp pays 21% federal corporate tax on profits, then shareholders pay tax again on dividends. Sounds bad — but C Corps get the qualified small business stock (QSBS) exclusion, unlimited shareholders, and are the only structure VCs will fund.

When S Corp Election Makes Sense

The S Corp math only works when profit exceeds the extra costs:

• Payroll processing: ~$500-1,000/year
• Extra accounting: ~$500-1,500/year
• Reasonable salary requirement: the IRS audits S Corps that pay $20K salary on $200K profit

Rule of thumb: S Corp election pays off when consistent profit exceeds ~$60,000-80,000/year. Below that, the compliance costs eat the savings.

When C Corp Makes Sense

Choose C Corp only if:

• You are raising venture capital (VCs require Delaware C Corps)
• You plan to issue stock options to employees
• You want QSBS treatment (up to $10M tax-free gain on exit after 5 years)
• You will reinvest profits rather than distribute them

For a lifestyle business or freelance operation, C Corp double taxation is a waste.

Liability: All Three Protect You

LLC, S Corp, and C Corp all create a legal wall between business debts and personal assets. The protection is identical — the differences are tax and compliance, not liability. The wall only holds if you keep finances separate: dedicated business bank account, no personal expenses on the business card.

How to Decide

Choose LLC if:

• Profit is under $60K/year or inconsistent
• You want minimal paperwork
• You are a freelancer, consultant, or small local business
• You might elect S Corp later (you can — it is just a form)

Choose S Corp election if:

• Consistent profit above $60-80K
• You are willing to run payroll
• You want to cut self-employment tax legally

Choose C Corp if:

• You are raising outside investment
• You are building to sell or go public
• You need stock options for hiring

Frequently Asked Questions

Can I switch from LLC to S Corp later?

Yes. File Form 2553 with the IRS — your LLC stays an LLC legally but is taxed as an S Corp. Deadline: within 75 days of the tax year start, or anytime for next-year effect.

What is a "reasonable salary" for an S Corp?

What you would pay someone else to do your job. The IRS looks at industry benchmarks, your experience, and hours worked. A common safe harbor is 40-60% of profit, but document your reasoning.

Is an LLC or S Corp better for a side business?

LLC. Side businesses rarely clear the $60K profit threshold where S Corp savings beat the payroll and accounting costs.

Do I need a lawyer to form an LLC?

No. File directly with your state ($50-500 depending on state) or use a formation service. Lawyers are only worth it for multi-member LLCs needing custom operating agreements.

Which state should I form in?

Your home state for 95% of small businesses. Delaware and Wyoming only make sense for C Corps raising VC money or businesses wanting specific legal frameworks — otherwise you pay fees in two states.

Bottom Line

Start as an LLC — it is cheap, simple, and protects you. When profit consistently exceeds $60-80K, elect S Corp taxation to cut self-employment tax. Only go C Corp if investors require it. The structure should follow the money, not the other way around.
