LLC vs Corporation: Key Differences, Taxes & Which to Choose

An LLC and a corporation are both state legal entities you form with the Secretary of State (or equivalent). They protect personal assets differently from a sole prop, but they diverge on taxes, ownership rules, formalities, and how investors usually expect you to be set up. "Corporation" on state forms usually means a C corporation by default for federal tax; an S corporation is a tax election, not a separate formation type — see LLC vs S corp and Form 2553.

Facts below are from the SBA business-structure guide and IRS pages on LLCs, forming a corporation, S corporations, LLC filing as a corporation or partnership, and Form 8832, checked on 2026-10-19. This is general education, not legal or tax advice.

What each one actually is

Per the SBA, your business structure affects taxes, fundraising, paperwork, and personal liability. You choose a structure before you register with the state. Converting later is possible in many places, but it can mean tax consequences and extra filings — so start with the structure that matches how you expect to own and fund the company.

Limited liability company (LLC). The SBA describes an LLC as combining corporation-style liability protection with partnership-style pass-through taxation. Owners are called members. The IRS notes that an LLC is allowed by state statute (rules vary by state), members may include individuals, corporations, other LLCs, and foreign entities, there is no IRS maximum number of members, and most states allow single-member LLCs. A few businesses (for example banks and insurance companies) generally cannot be LLCs — check your state and federal rules.

Corporation (C corp by default). The SBA calls a corporation a legal entity separate from its owners that can make a profit, be taxed, and be held legally liable. Owners are shareholders. For federal tax, the IRS treats a C corporation as a separate taxpaying entity: it conducts business, realizes income or loss, pays tax, and may distribute profits as dividends. Forming one usually means articles of incorporation, bylaws, a board, and more ongoing formalities than a typical LLC.

S corp is not a third state entity. An S corporation is a federal tax status. The IRS says S corps elect to pass income, losses, deductions, and credits through to shareholders, avoiding the classic double tax on C corp profits — with eligibility limits (domestic entity, ≤100 shareholders, one class of stock, no nonresident alien shareholders, among others). You file Form 2553 to elect. An eligible LLC can become S-corp taxed without first filing Form 8832 in the usual case — details in our Form 2553 guide.

Side-by-side comparison

Taxes: pass-through vs double taxation

Default LLC. The IRS LLC page explains classification by elections and member count: a domestic LLC with at least two members is classified as a partnership unless it files Form 8832 and elects corporation treatment; a one-member LLC is a disregarded entity (activity on the owner's return) unless it elects corporation treatment. For employment and certain excise taxes, a single-member LLC is still treated as a separate entity.

If the LLC is a partnership, the IRS says normal partnership rules apply: file Form 1065, owners get Schedule K-1s, and members generally pay self-employment tax on their share of partnership earnings. A disregarded single-member LLC owned by an individual typically reports on Schedule C with the same SE-tax pattern as a sole prop — forming the LLC alone does not remove SE tax. The later SE-tax planning move for eligible US owners is often an S-corp election (reasonable salary + distributions), which adds payroll cost.

C corporation. Per the IRS, corporate profit is taxed to the corporation when earned, and again to shareholders when distributed as dividends — a double tax. The corporation does not deduct dividends, and shareholders cannot deduct corporate losses on their personal returns the way partnership/S-corp owners often can with pass-through losses (subject to basis and other limits).

Electing corporate or S-corp tax for an LLC. Form 8832 (Entity Classification Election) lets an eligible entity choose to be classified as a corporation, a partnership, or a disregarded entity. The IRS LLC page notes an election generally cannot take effect more than 75 days before it is filed, or more than 12 months after. If the LLC is treated as a corporation, it files Form 1120 as a C corp — unless a qualifying LLC elects S status and then files Form 1120-S. For the S path, see Form 2553.

Liability, formalities, and day-to-day life

Both structures are designed so owners are generally not personally liable for business debts the way a sole proprietor is. The SBA still stresses that protection has limits, and insurance matters for risks you could not pay out of pocket. Courts can pierce the veil when owners ignore separation — mixing personal and business money, undercapitalizing, or treating the entity as a personal wallet. Keep a dedicated bank account, sign contracts in the entity's name, and document major decisions.

Corporations usually demand more ritual: board meetings, minutes, stock ledgers, and officer roles. LLCs lean on the operating agreement for profit splits, voting, and what happens if a member leaves. Some states historically treated membership changes as ending the LLC unless the agreement said otherwise — the SBA still flags limited-life / membership-change issues in many states, so write the agreement carefully.

Formation cost is a state filing fee plus a registered agent and any annual report or franchise tax. Those amounts vary widely; compare our LLC cost guide and fees by state. Corporation filing fees are often in a similar ballpark in the same state, but ongoing corporate formalities and tax returns (Form 1120) usually cost more in accounting time.

Fundraising, employees, and growth path

The SBA notes corporations have an advantage raising capital because they can sell stock, which also helps attract employees with equity. Many US venture-backed startups form a Delaware C corporation because investor docs, preferred stock, and option plans are standardized that way. An LLC can raise money and issue profits interests, but the paperwork is less familiar to traditional VC funds.

If you expect to stay owner-operated, take profits as distributions, and skip institutional equity rounds, an LLC is often the simpler state entity. If you plan priced equity rounds, a large option pool, or a path to IPO/acquisition with institutional investors, start closer to a C corp (often Delaware) and get counsel early.

State of formation still matters. If you live and sell in one US state, forming there is usually cheapest overall — see best state to form an LLC. Popular low-friction states for remote or non-resident founders include Wyoming; always weigh foreign-qualification costs if you already have a home state.

Non-US owners (including Hong Kong–based founders)

The IRS allows foreign entities to be LLC members in many cases, and non-US individuals commonly own US LLCs. By contrast, the IRS S corporation rules disallow nonresident alien shareholders — so S-corp status is off the table if any owner is a nonresident alien. Non-resident founders often prefer a default-taxed LLC (or a C corp when investors demand it) rather than chasing S-corp payroll-tax savings.

This site's founder, Simon Chan, is based in Hong Kong and runs a Wyoming LLC as a non-resident — documenting banking, EIN, and compliance from that angle on the About page. Non-residents still need US tax advice (and advice at home): trade-or-business rules, withholding, and filing obligations depend on the facts. Get an EIN after you form; many non-US applicants cannot use the IRS online tool and apply by phone, fax, or mail.

Which should you choose?

• Choose an LLC if you want liability protection, flexible ownership, pass-through tax by default, lighter formalities, and you are not raising traditional VC. Most small service businesses, agencies, and e-commerce brands start here. Eligible US owners can add an S-corp election later via Form 2553 if the numbers justify payroll.
• Choose a C corporation if you need multiple stock classes, plan institutional fundraising, want a familiar equity/option structure, or have owners who cannot (or should not) use pass-through taxation the same way.
• Do not confuse "S corp" with the formation choice. Decide LLC vs corporation at the state first; treat S corp as a later tax election if you qualify. Deep dive: LLC vs S corp.
• Still a sole prop? Read sole proprietorship vs LLC before you incorporate anything.
