LLCs offer pass-through taxation and light formalities; C-Corps offer stock, investors, and QSBS. Comparison table, tax math, and a three-question decision framework.
By Omer Aydin ·
The short answer for 2026: choose an LLC if your business is funded by its own revenue, and a C-Corp if it will be funded by investors. An LLC's profits pass through to your personal tax return once and the entity requires almost no formalities; a C-Corp pays its own taxes and demands board-level paperwork, but it is the only structure venture capital accepts — and the only one whose stock qualifies for the QSBS capital-gains exclusion.
Both protect your personal assets equally. Here is the full comparison, the tax math, and the three questions that resolve nearly every case.
| Factor | LLC | C-Corp |
|---|---|---|
| Liability protection | Yes | Yes |
| Taxation | Pass-through — profits taxed once, on owners' returns | Entity pays 21% federal; dividends taxed again to shareholders |
| Self-employment tax | Members pay SE tax on active income (~15.3%) | Founders are W-2 employees; payroll taxes apply to salary |
| Formalities | Minimal — no board, no required meetings | Board of directors, bylaws, resolutions, stock ledger |
| Ownership | Membership interests, any split by agreement | Shares — uniform, transferable, option-pool friendly |
| Investors | Most VCs won't invest in LLCs | The standard — SAFEs, preferred rounds, option pools |
| QSBS (Section 1202) | Not available | Up to 100% federal capital-gains exclusion at exit (limits apply) |
| Employee equity | Profits interests (unfamiliar, complex) | Stock options (standardized, expected) |
| Best state | Wyoming for most | Delaware, almost always |
| Annual state cost (typical) | $60 (WY) – $300 (DE) | ~$450 DE franchise tax + $50 report |
LLC (default): the entity files an information return (or nothing, for single-member), and profits land on your personal return whether or not you withdrew the cash. You pay income tax plus, on active business income, ~15.3% self-employment tax. One layer, simple, and losses can offset other income in early years.
C-Corp: the corporation pays 21% federal tax on profits. Money reaching founders is taxed again — as salary (payroll taxes) or dividends (capital-gains rates). This "double taxation" sounds disqualifying but often isn't: startups reinvest everything (no dividends, minimal second layer), and a 21% flat rate on retained earnings can beat a founder's top marginal rate on pass-through income.
The S-Corp wrinkle: an LLC can elect S-Corp taxation — keeping pass-through treatment while splitting owner income into salary plus distributions, which trims self-employment tax once profits are consistently six figures. Restrictions apply (≤100 shareholders, US persons only, one class of stock), which is also why S-elections and venture capital don't mix.
The QSBS factor: Qualified Small Business Stock is the quiet giant of this decision. Stock in a qualifying C-Corp held five years can be sold with up to 100% of federal capital gains excluded (subject to the statutory cap). For a founder who exits for $10M+, QSBS alone can dwarf every other tax consideration on this page — and LLC interests never qualify (though the QSBS clock starts at conversion).
When the answers conflict — profitable and might raise someday — the common path is start as an LLC, convert to a Delaware C-Corp when fundraising becomes concrete. Delaware's statutory conversion makes this a routine filing, not a re-formation.
For distributed profits, the LLC — one layer of tax instead of two. For aggressive reinvestment or an eventual stock sale, the C-Corp can win via the 21% flat rate and the QSBS exclusion. The honest answer is that "better" flips with your margin, salary needs, and exit plan; model both at real numbers.
Fund structures and tax: LLC income passes through to investors (creating tax headaches for their LPs, including foreign and tax-exempt ones), and LLCs lack standardized stock mechanics — preferred shares, option pools, SAFEs. Delaware C-Corp documents are an industry standard every law firm can close on.
Yes — Delaware and most states offer statutory conversion, and it is a well-trodden pre-fundraise step. It involves filings, possible tax consequences, and legal review, so if VC funding is clearly the plan, starting as a C-Corp is cheaper than converting under term-sheet pressure.
Section 1202 lets holders of Qualified Small Business Stock — original-issue C-Corp stock held five years, in a company under $50M of assets at issuance — exclude up to 100% of federal capital gains at sale, within statutory caps. It applies only to C-Corp stock, and for venture-scale exits it is frequently the single largest tax lever a founder has.
Yes — both create the same liability shield when properly maintained. The C-Corp's extra formalities aren't extra protection; they are governance plumbing for shareholders and boards.
LLCs: Wyoming for cost and privacy, your home state if you operate physically there — see Wyoming vs. Delaware. C-Corps: Delaware, nearly without exception, because that is where investors and case law are.
