LLC vs S-Corp vs C-Corp: Which Business Structure Saves the Most in Taxes?
The entity structure question is asked constantly and answered incorrectly just as often. LLC, S-Corp, and C-Corp are not just legal structures — they are tax decisions that compound over years. The right answer depends on your profit level, how you take money out, and whether you plan to raise institutional capital.

The Quick Answer
LLC (taxed as sole proprietor or partnership) is the right starting point for most small businesses — simple, flexible, and no double taxation. Elect S-Corp status when your net profit consistently exceeds $50K/year — the self-employment tax savings become meaningful at that level. C-Corp is required if you plan to raise venture capital, issue stock options, or eventually go public.
Side-by-Side Breakdown
LLC (default, pass-through): All net profit is subject to self-employment tax (15.3% on the first $168,600 of net earnings in 2026). Income passes through to your personal return. Simple to maintain. No double taxation.
LLC with S-Corp Election: Still pass-through taxation. You pay yourself a reasonable salary (subject to payroll taxes) and take remaining profit as a distribution (not subject to self-employment tax). Saves 15.3% SE tax on the distribution portion. Adds cost: payroll setup, quarterly filings, and CPA fees.
C-Corp: Corporate income taxed at 21% (federal). Owners also pay tax on dividends or salary — this is double taxation. However, C-Corps can issue multiple share classes, retain earnings at the lower corporate rate, and are required for VC investment.
When to Stay an LLC
Your net profit is under $50K/year — the S-Corp savings do not offset the added administrative cost. You want the simplest possible structure while you validate the business. You are a solo founder without plans to bring on institutional investors. You want maximum flexibility in how you allocate profit and loss among members.
When to Elect S-Corp Status
Your LLC is generating consistent net profit over $50K/year. You are currently paying self-employment tax on all of that profit and want to reduce the SE tax burden. The math: if your business earns $150K in profit and you pay yourself a reasonable salary of $80K, you save SE tax on the remaining $70K distribution — approximately $10K in annual tax savings.
When to Form a C-Corp
You plan to raise money from venture capital or institutional investors — VCs require C-Corps because they need preferred stock. You plan to offer stock options to employees through a qualified stock option plan (ISOs require a C-Corp). You want to retain earnings in the business at the 21% corporate rate rather than pulling them out at your personal rate.
The Verdict
Start as an LLC. Make the S-Corp election when your CPA confirms the SE tax savings exceed the additional compliance cost (typically at $50K-$80K in net profit depending on your state). Convert to a C-Corp if you decide to raise VC. Do not form a C-Corp speculatively — the administrative overhead is real and the double-taxation problem is real if your business does not raise institutional capital.
How to Get Started
LLC formation: File Articles of Organization with your state ($50-$500 depending on state). Get an EIN from irs.gov (free, takes 5 minutes online). Open a business bank account.
S-Corp election: File IRS Form 2553 within 75 days of the start of the tax year you want it to apply. Have a CPA calculate your reasonable salary before you file.
C-Corp: Incorporate in Delaware (the standard for VC-backed companies). Use Stripe Atlas, Clerky, or a startup lawyer. Set up a 83(b) election if you are issuing founder shares with vesting.

FREQUENTLY ASKED QUESTIONS
Can I switch from an LLC to an S-Corp later?
Yes. An LLC can elect S-Corp tax treatment without changing its legal structure. File IRS Form 2553. The election must be made within 75 days of the tax year start.
What is a reasonable salary for S-Corp purposes?
The IRS requires that S-Corp owner-employees pay themselves a salary comparable to what the position would pay in an arm's-length transaction. CPAs typically recommend 40-60% of total S-Corp profit as salary, with the remainder taken as distribution.
Does forming a Delaware C-Corp mean I pay Delaware taxes?
Delaware has a franchise tax (minimum $175-$400/year for small companies). You do not pay Delaware income tax unless you have business operations or employees in Delaware.
