Liability Is Not the Deciding Factor Here
Most comparisons open by explaining that both structures protect personal assets. That is true, and it settles nothing. By statute, a member of an LLC is not personally liable for the company's debts, and neither is a shareholder in a corporation. If liability were the whole question, everyone would file the cheaper document and stop. This comparison exists because the two entities issue different things to their owners, and outside money cares enormously about which.
An LLC issues membership interests. What those interests entitle you to is whatever the members wrote down in the operating agreement, a private contract the state never sees. A corporation issues shares of stock, recorded in a stock ledger, governed by a charter filed with the state and by bylaws the board adopts. One instrument is bespoke and invisible. The other is standardized and on the record. That difference is the whole comparison, and everything below follows from it.
Be precise about the phrase C corporation, because it names a tax status, not a filing. You file articles of incorporation and you get a corporation, taxed under subchapter C unless it elects subchapter S, a separate decision covered in C corporation vs S corporation. On the LLC side, the IRS treats a single-member LLC as an entity disregarded as separate from its owner, and a multi-member LLC as a partnership, unless it files to change that. The entity itself is described in what is an LLC.
What Each One Can Issue, and Who Can Hold It
| The question you are actually asking | LLC | C corporation |
|---|---|---|
| What owners hold | Membership interests defined in a private agreement | Shares recorded in a stock ledger |
| Who sets the terms | The members, in whatever language they like | The charter, the bylaws and state corporate law |
| Default federal tax | Disregarded with one member, partnership with two or more | The corporation files and pays its own tax at 21 percent |
| Second layer of tax | None by default | Yes, on profit distributed as a dividend |
| Section 199A deduction | Available to the members | Never available on the corporation's income |
| Section 1202 stock | Membership interests are not stock | Available if the corporation and the stock qualify |
| Employee equity | Profits interests, valued and papered case by case | Options and restricted stock, off the shelf |
| Formation fee in the File.Business fee table | $50 in Arizona, $99 in Ohio, $110 in Delaware, $300 in Texas | $60 in Arizona, $99 in Ohio, $89 in Delaware, $300 in Texas |
| Recurring state filing | Annual or biennial report in most states | The same report, plus minutes, a board and an officer slate |
Two lines in that table do most of the work. The section 199A row is what makes the LLC cheaper for a profitable operating business. The section 1202 row is what makes the corporation valuable to a founder who expects an exit, and it is available only for stock in a C corporation, because IRC 1202(c) says so. Everything else is administration.

Why an Institutional Investor Asks for a Corporation
Venture funds do not ask for a corporation out of habit. Four things push them there, and none of them is negotiable by a founder without a competing term sheet.
The first is preferred stock. A priced round buys shares carrying a liquidation preference, anti-dilution protection, and a protective voting block. You can write all of that into an LLC agreement, but you have to draft it from scratch each time, rather than pull it from a document set the whole market already knows.
The second is the investor's own tax position. Funds with tax-exempt limited partners treat pass-through income from an operating LLC as a live problem. The usual fix is to insert a blocker corporation, which costs money and adds a return. Buying stock in a corporation avoids the question entirely.
The third is timing: an LLC taxed as a partnership issues a Schedule K-1 to every member. A fund holding fifty positions, each delivering a late K-1, has fifty reasons to extend its own filings. Stock produces no K-1. The fourth is the option pool, which the next section takes apart.
Note that investors ask for Delaware because they want the case law and the forum, not because the fees are low. For an operating business the ranking is in best state to form an LLC and the procedure is in how to choose a state for your LLC.
The Tax Cost of a C Corporation, and What Offsets It
Publication 542 puts the rate plainly: corporations figure their tax by multiplying taxable income by 21 percent, and the return is due by the fifteenth day of the fourth month after the tax year ends. That rate is not administrative practice; IRC 11(b) fixes it. Take $400,000 of profit. The corporation pays $84,000, and $316,000 remains inside the company. Pay all of it out as a dividend to a shareholder in the 15 percent long-term band, and another $47,400 is due. So $131,400 of the original $400,000 is federal tax, and the effective rate is 32.9 percent.
The same $400,000 earned inside an LLC taxed as a partnership is taxed once, on the members' own returns, and may carry the section 199A deduction of up to 20 percent of qualified business income. The IRS is direct about who cannot have it: income earned through a C corporation, or by providing services as an employee, is not eligible.
For 2026 the threshold above which the deduction starts to be limited is $201,750 on a single return and $403,500 on a joint return, set in Revenue Procedure 2025-32. The mechanics of the pass through side are worked through in the LLC taxes guide.
Now the offset. A corporation is only taxed twice on money it actually hands to shareholders. A company that puts every dollar back into inventory, tooling, or a plant pays 21 percent once and stops. If the owners take no distributions for six years, the second layer never arrives in those six years. That is the honest case for the C corporation outside the venture track. But it is narrower than it sounds, because the accumulated earnings tax of IRC 531 exists to stop a corporation from hoarding profit indefinitely to postpone shareholder-level tax.
Section 1202 Stock Only Exists Inside a Corporation
This is the provision that decides the entity question for a founder who expects to sell, and it is the one most first-time founders have never priced. Section 1202 lets a holder of qualified small business stock exclude gain on a sale. The IRS explains that if you hold qualifying stock acquired after July 4, 2025 for five years or more, you could exclude up to 100 percent of the gain. The aggregate excluded gain per issuer rises to $15 million for stock acquired after that date. Whatever part of the gain is taxable gets taxed at a maximum 28 percent rate.
The word doing the work is stock. Membership interests are not stock, so no amount of drafting makes them qualify. An LLC that checks the box to be taxed as a corporation is still an LLC under state law. The second thing that matters is the clock: the holding period runs from when the company issues the stock.
A founder who spends three years as an LLC and converts at the Series A has banked nothing, because the stock did not exist. Everyone starts at zero on conversion day, which is why a company with a plausible exit inside seven years is usually better off incorporating at the start.
Where Equity Compensation Strains an LLC
A corporation grants an option, the employee signs one page, and the whole arrangement sits on a plan the company adopted once. An LLC has no stock to option. The usual substitute is a profits interest, which gives the holder a share of future appreciation above a threshold set on the grant date, and it works. But it is also more expensive to run. You must establish the threshold value, amend the agreement for each grant, and the recipient generally becomes a member of the LLC rather than an employee of it.
That last consequence is the one that surprises people. Turning an employee into a member usually moves them off a W-2 and onto a Schedule K-1. That means no payroll withholding, quarterly estimated payments they were not making before, and a tax return that arrives later than they are used to. Ten engineers means ten of those conversations. The distinction between the two payroll worlds is set out in independent contractor vs employee, and how owners take money out of an LLC in the first place is in how to pay yourself from your LLC.
None of this makes equity in an LLC impossible. It makes it a project, so price a lawyer's time into the LLC column before deciding it is the cheaper structure.
Converting an LLC to a Corporation Later
Three routes exist, and they are not equivalent. A statutory conversion, available in most states, turns the LLC into a corporation in a single filing that preserves the entity, its EIN, and its contracts. A merger into a newly formed corporation reaches the same place, but with two entities and more paper. A contribution of the membership interests to a new holding corporation leaves the LLC alive underneath as a subsidiary, sometimes what a buyer wants, rarely what a seed investor wants.
None of the three is a tax election. Form 8832 can classify an LLC as an association taxable as a corporation. The instructions state that the election cannot take effect more than 75 days before the date the election is filed, nor later than 12 months after, with a 60 month lock on changing again. Filing it gets you corporate tax treatment and no shares. An investor buying preferred stock needs a corporation under state law, so the box-checking route solves the wrong half of the problem.
Budget honestly. Counsel to run a clean conversion. Adopt bylaws, authorize a share count, issue founder stock, paper the 83(b) elections, and set up an option plan. Is a low five-figure engagement in most markets. The state filing is the smallest number in the exercise: in the File.Business fee table, a Delaware LLC costs $110 to form and a Delaware corporation $89.
Five Questions That Settle It
Answer these in order and stop at the first yes.
- Is a priced equity round a real plan for the next 24 months, with named investors? If yes, incorporate. A term sheet is not the moment to be reading about statutory conversions.
- Do you intend to grant equity to more than five people? If yes, the corporation is cheaper to administer even before anyone invests.
- Is a sale of the company inside seven to ten years a serious possibility? If yes, the section 1202 clock is worth more than the pass through deduction, and it only runs on stock.
- Will the business consume its own profit for years rather than distribute it? If yes, one layer of 21 percent may genuinely beat a top individual rate.
- None of the above? Form the LLC. It is cheaper to file, cheaper to keep, and it hands the profit to the people who earned it once rather than twice. How to start an LLC covers the filing.
Five Mistakes in the LLC and C Corporation Decision
Mistake 1: Incorporating for a round that never comes
A corporation formed on the strength of a fundraising plan that stalls leaves the founder with an entity-level return, a board, minutes, an officer slate, and no section 199A deduction, in a business that turned out to be a consultancy. Most companies that plan to raise do not raise. Form for the business you have, and convert when a term sheet is on the table.
Mistake 2: Treating Form 8832 as a substitute for incorporating
Checking the box changes the tax return and nothing else. The entity is still an LLC, it still issues membership interests, and no investor document set fits it. Worse, the 60 month lock means undoing the election is not a free decision if the plan changes again.
Mistake 3: Assuming double taxation means double the tax
The second layer only lands on distributed profit. A corporation that pays salaries and reinvests the rest is taxed once, in that year. The phrase describes a mechanism, not an outcome. Using it as a reflex leads people to reject the corporation in exactly the capital-hungry cases where it fits.
Mistake 4: Forgetting that the section 1202 clock starts at issuance
Founders who spent four years building inside an LLC often assume the holding period traveled with them through the conversion. It did not. If an exit is plausible and near, that arithmetic can be worth more than every other line on this page combined.
Mistake 5: Forming the corporation and never running it as one
A corporation with no adopted bylaws, no issued stock, no board consents, and no annual meeting is the easiest kind of entity for a creditor to attack. If you choose the corporation, adopt the bylaws in the first month, and keep the ledger current. The requirements are in corporate bylaws.
Three Companies and the Entity Each One Chose
Example one: a diagnostics startup in Durham
Sablefish Diagnostics had two technical founders, a grant of $180,000, and a lead investor circling a $4 million seed. They formed a North Carolina LLC first, because it cost $125 with a $200 annual report, and they needed a bank account in week one. Eleven months later the term sheet arrived, and the conversion cost $14,000 in legal fees and six weeks. Both founders' section 1202 clocks started on conversion day. The LLC saved them about $600 in year one, and cost them eleven months of holding period on stock they intend to hold for eight years.
Example two: a tooling shop in Toledo
Ridgeway Tool Works clears about $310,000 of profit on $1.9 million of revenue, and reinvests almost all of it into machines. The owner priced both structures. As an Ohio LLC the profit passes through once and may carry a section 199A deduction of up to 20 percent. As a corporation the same profit would attract $65,100 of federal tax at 21 percent before a dollar reached him, and he would lose the deduction permanently.
He stayed an LLC. Ohio charges $99 to form either entity and no annual report fee, so the state cost was identical and the federal difference decided it.
Example three: a battery company in Reno
Ashgrove Cells burns cash by design: three years of losses, $2.4 million raised across two rounds, nineteen employees holding options. It was a Delaware corporation from day one, formed for $89, and qualified to do business in Nevada, where the plant sits. None of the pass-through arithmetic applied, because there was no profit to pass through. What mattered was that nineteen option grants came off a shelf, rather than a lawyer's desk.
What Happens When the Choice Is Wrong: The Penalty in Dollars
Put figures on both failure modes, because they are not symmetrical.
Incorporating too early is a running cost. A profitable one-owner business making $200,000 that files as a corporation pays 21 percent, or $42,000, before the owner is paid anything beyond salary. It also forfeits a section 199A deduction that on the same profit could have been worth roughly $40,000. At a 24 percent marginal rate, that deduction is worth about $9,600 of tax. So the combined annual cost of the wrong choice sits in the low five figures every year it continues, plus an entity return the LLC would not have filed.
Incorporating too late is a single large number. Take a founder whose stock is worth $6 million at exit, with a near-zero basis. Held five years as qualifying section 1202 stock, the gain can be excluded up to the per-issuer cap. Held four years, because the conversion happened eleven months later than it could have, none of it is excluded. At a 20 percent long-term capital gains rate, that is $1.2 million of federal tax on the same sale. The conversion that would have avoided it cost $14,000.
A smaller and far more common penalty is worth naming. An entity that lets its state registration lapse loses good standing, and a lapsed entity cannot deliver the certificate of good standing every investor's closing checklist demands. Reinstatement in most states means back reports and back fees before the certificate will issue. Deadlines are collected in business filing deadlines by state.
Where to Read Next
If the real question was whether the corporation should sit under subchapter S rather than subchapter C, that is in C corporation vs S corporation. If you have an LLC and an accountant has raised the S election to cut self employment tax, the arithmetic is in when the S corp election pays for itself. If you have registered nothing yet, start at LLC vs sole proprietorship. If you are forming with other people, read LP vs LLP vs LLC. And if you only needed a better trading name, that is LLC vs DBA.
LLC vs C Corporation FAQ
Is a C corporation better than an LLC?
Neither is better in the abstract. A C corporation is the right vessel when the business will issue stock to people who are not running it, run an option pool, or hold stock its founders hope will qualify under section 1202. An LLC is the cheaper and simpler answer for a business whose profit goes to the people who earn it.
Do I have to be a C corporation to raise money?
No. Angel investors, revenue-based lenders, and friends and family all fund LLCs. Priced equity rounds led by venture funds are the case where the corporation is close to mandatory, because the documents, the preferred stock, and the investors' own tax position all assume corporate stock.
Can an LLC just elect to be taxed as a C corporation instead?
It can. Form 8832 lets an eligible entity be classified as an association taxable as a corporation, and the election cannot take effect more than 75 days before it is filed or later than 12 months after. That changes the tax treatment only. Under state law the entity is still an LLC issuing membership interests, which is not what an investor is asking for.
What is the federal tax rate on a C corporation?
The IRS states that corporations figure their tax by multiplying taxable income by 21 percent. Profit paid out to shareholders as a dividend is then taxed again on their own returns, which is the second layer people mean when they say double taxation.
Does a C corporation get the 20 percent qualified business income deduction?
No. The IRS is explicit that income earned through a C corporation, or by providing services as an employee, is not eligible for the section 199A deduction. The deduction belongs to owners of sole proprietorships, partnerships and S corporations.
Will converting my LLC to a corporation later cost me anything?
Usually legal fees in the low five figures, a new state filing, a new stock ledger, and a fresh set of 83(b) decisions. The cost people miss is the section 1202 holding period. It starts when the company issues the stock, so a conversion at the Series A resets the five year clock for every founder.
Can a non US person own a C corporation?
Yes. A C corporation has no restriction on who may hold its shares, and neither does an LLC. That is one of the practical differences between a C corporation and an S corporation, because subchapter S bars nonresident alien shareholders outright.
