LLC vs. C Corporation

How Each Is Taxed

This is the core difference. A C corporation is its own taxpayer: it files Form 1120 and pays federal income tax on its profit at a flat 21% rate under 26 U.S.C. § 11. If the corporation then distributes any of that already-taxed profit to shareholders as a dividend, the shareholders pay tax on it again on their personal returns, a structure known as double taxation. An LLC, by default, isn't a separate taxpayer at all: a single-member LLC is disregarded, with profit reported directly on the owner's return, and a multi-member LLC is taxed as a partnership, with profit passed through to each member's own return. Either way, LLC profit is generally taxed only once, at the owner level.

Ownership Structure

A C corporation can have an unlimited number of shareholders, of any type, individuals, other corporations, trusts, or foreign investors, and can issue multiple classes of stock with different rights, such as preferred stock for investors. An LLC's ownership is more flexible in a different way: state law lets an LLC admit members with ownership splits set entirely by the operating agreement, without the stock-certificate formalities a corporation uses, though an LLC generally can't offer the same kind of standardized, easily transferable stock instruments.

Raising Outside Investment

Institutional investors, particularly venture capital funds, overwhelmingly prefer investing in C corporations. A corporation's stock structure supports standardized investment terms, preferred stock with specific investor protections, and an employee stock option pool, none of which an LLC's membership-interest structure replicates in the same way. This is the main reason many startups planning to raise venture capital either incorporate directly or convert from an LLC to a C corporation before a funding round.

Management and Required Formalities

A C corporation's state law generally requires a board of directors elected by shareholders, corporate officers, and documented annual meetings with minutes kept as part of the corporate record. An LLC has no equivalent default requirement: members can manage the LLC directly, or designate managers, with the rules set in the operating agreement rather than dictated by a standard corporate governance structure. This makes an LLC simpler to run day to day for an owner who doesn't need a board or formal shareholder meetings.

Employee Equity Compensation

A corporation can grant stock options, giving employees the right to buy stock at a set price later, a widely used and well-understood form of equity compensation. An LLC instead typically grants a profits interest, a share of the LLC's future profit and value growth, which works differently for tax purposes and is less standardized across employees and platforms that manage equity compensation.

Self-Employment Tax vs. Payroll Tax on Owners

An LLC owner who's active in the business generally pays self-employment tax on their share of the LLC's profit, since that profit isn't run through payroll. A C corporation shareholder who works for the company is instead a W-2 employee, paid a salary subject to payroll tax withholding, while dividends paid on top of that salary aren't subject to self-employment tax, though they are subject to the double taxation described above.

A Capital Gains Benefit Unique to Corporate Stock

Stock in a qualifying C corporation can be eligible for a federal capital gains exclusion under Internal Revenue Code Section 1202 for qualified small business stock, if specific holding-period and eligibility requirements are met. This exclusion applies only to corporate stock, not to an LLC's membership interests, so it's a factor worth discussing with a tax professional if the business may eventually be sold.

Converting Between the Two

An existing LLC can convert to a corporation, and in some states an existing corporation can convert to an LLC, through a formal state filing process, sometimes called a statutory conversion where state law allows it, or through a merger-based restructuring where it doesn't. Either path involves its own paperwork, state fee, and tax consequences, so it's worth choosing the right structure up front when possible rather than planning to convert later as a routine step.

State-Level Taxes Can Differ From the Federal Picture

Some states impose their own franchise tax or minimum tax on corporations that doesn't apply the same way to an LLC, or vice versa, and a few states tax LLCs and corporations similarly despite the federal differences. Check your specific state's treatment of each structure in addition to the federal rules described here.

Converting From an LLC to a C Corporation Is Common, Not Unusual

Many startups form as an LLC early on, then convert to a Delaware C corporation once they're preparing to raise venture capital. This conversion is a real filing process with its own cost and paperwork, so it's worth planning for in advance rather than treating it as a quick last-minute step before closing a funding round.

Double Taxation Isn't Automatic in Every Case

A C corporation only faces the second layer of tax when it actually distributes profit as a dividend; a corporation that reinvests all its profit back into the business doesn't trigger shareholder-level dividend tax in that year. Whether this matters for your business depends on your specific plans for distributing versus reinvesting profit.

This Isn't Tax Advice

Which structure results in a lower overall tax burden depends heavily on your profit level, your plans for distributing or reinvesting earnings, and whether you're pursuing outside investment. Talk to a tax professional before choosing between an LLC and a C corporation, rather than relying on a general comparison.

Both Still Need a Registered Agent and Annual Filings

Regardless of which structure you choose, every state requires a registered agent with a physical address in the state of formation, and both an LLC and a corporation typically owe some form of periodic state filing to stay in good standing. Neither structure avoids these baseline state-level obligations.

Consider How You'll Eventually Exit

If you expect to sell the business or take on institutional investors eventually, think through how that transaction would work under each structure, since a stock sale of a corporation and a sale of LLC membership interests are taxed and documented differently. Planning the end goal early can influence which structure makes more sense from the outset, rather than defaulting to whichever one seems simplest today.
