LLC vs C-Corp: Which is Right for You?
Choose an LLC if you want low running costs, profits taxed once, and you are not raising venture capital soon. Choose a C-Corp if you plan to raise from institutional investors, issue stock options, or keep most profit in the company. For founders outside the US, the answer also depends on how your home country taxes each structure.
Key takeaways
- Both structures protect your personal assets from business debts when you run them properly.
- An LLC is taxed once, at the owner level, by default. A C-Corp pays 21% federal tax on profit, and dividends are taxed again.
- Most US venture funds invest only in C-Corps, usually Delaware C-Corps.
- For a nonresident owner, a single-member LLC with no US business presence often owes little US income tax, while a C-Corp pays US corporate tax on all its profit.
- You can start as an LLC and convert later, but conversion has tax and legal costs, so decide with your next 2 to 3 years in mind.
Side-by-side comparison
| Factor | LLC | C-Corp |
|---|---|---|
| Owners called | Members | Shareholders |
| Default federal tax | Pass-through (disregarded or partnership) | 21% corporate tax, then tax on dividends |
| Governing document | Operating Agreement | Bylaws, board and shareholder resolutions |
| Equity for employees | Profits interests, harder to explain | Stock options, widely understood |
| Venture capital | Rarely accepted | Standard |
| Formalities | Light | Board meetings, minutes, share ledger |
| Annual federal return (foreign-owned) | Form 5472 with pro forma 1120 (single member) or Form 1065 | Form 1120, with Form 5472 if 25% or more foreign-owned |
How the tax actually differs
LLC
A single-member LLC is ignored for federal income tax; the owner reports the result. A multi-member LLC files a partnership return and passes income to members. For a US owner, this means one layer of tax plus self-employment tax on active income.
For a nonresident owner, the US only taxes income effectively connected with a US trade or business. A founder in Bengaluru running a design agency through a Wyoming LLC, with no US office or staff, often has no US income tax to pay. The LLC still files Form 5472 each year, and the founder's home country usually taxes the profit.
C-Corp
A C-Corp is its own taxpayer. It files Form 1120 and pays federal tax at a flat 21% on taxable profit, wherever the founder lives. When it pays a dividend to a foreign shareholder, US withholding generally applies at 30%, reduced by a tax treaty where one exists between the US and the shareholder's country.
The upside is that profit kept in the company is taxed only once, at 21%, until you distribute it. Growth companies that reinvest everything often prefer this.
The QSBS angle
US shareholders of qualifying C-Corps can exclude gain on sale under section 1202. The 2025 federal tax law raised the per-company exclusion cap to $15 million for stock acquired after July 4, 2025 and added partial exclusions for shorter holding periods. This mainly matters to US-taxpaying founders and investors, and it is one more reason investors ask for a C-Corp.
A simple worked example
Say your company earns $100,000 of profit in a year and you live in a country with no US tax treaty. As a C-Corp, the company pays $21,000 of federal tax. If it then pays the remaining $79,000 to you as a dividend, 30% withholding takes another $23,700, leaving $55,300 before any tax in your home country.
As a single-member LLC with no US trade or business, the same $100,000 may carry no US income tax at all, and your home country taxes it under its own rules. If the LLC does have effectively connected income, you file Form 1040-NR and pay graduated US rates on that profit instead. The gap between the two structures shrinks if the C-Corp keeps the profit to fund growth rather than paying it out.
Fundraising and equity
Venture funds often have their own investors who cannot receive pass-through income, so an LLC portfolio company creates tax problems for them. Standard seed documents such as SAFEs and preferred stock financings are written for corporations. If a priced round is on your roadmap within a year or two, starting as a Delaware C-Corp usually avoids a conversion later.
Employee equity is simpler in a C-Corp too. Stock options and restricted stock are familiar to candidates. LLC profits interests work but need more explanation and produce K-1s for every holder.
Cost and paperwork
State fees differ by state and entity type. In Delaware, an LLC pays a flat annual tax (the Division of Corporations lists $400, due June 1), while a corporation pays franchise tax based on a calculation method and files an annual report by March 1. Corporations also need a board, bylaws, issued shares and records of major decisions.
On the federal side, a C-Corp files Form 1120 every year even at a loss. A foreign-owned single-member LLC files the shorter pro forma 1120 with Form 5472. Either way, bookkeeping is the real ongoing cost.
Which one fits your situation
An LLC usually fits if:
- You are a solo founder, freelancer or small agency selling services
- You want to take profit out regularly
- You are not raising institutional money in the near term
- Your home country taxes you on the LLC profit anyway and you want to avoid a second layer
A C-Corp usually fits if:
- You are building a startup that will raise from US investors
- You want to grant stock options to a team
- You will reinvest profit rather than distribute it
- Your home country treats a US LLC oddly and a corporation more predictably

Converting an LLC to a C-Corp later
Many states allow a statutory conversion where the LLC becomes a corporation without a new company. Alternatively, an LLC can elect to be taxed as a corporation with IRS Form 8832 while staying an LLC under state law, although investors generally still want an actual corporation.
A conversion can be tax-free in many cases, but not always, and it resets some records: new EIN questions, new bank documents, new cap table. Budget time for it and involve a CPA and attorney.
Home-country questions to ask
Your country of residence matters as much as US law:
- Does your home country tax a US LLC's profit as it is earned, or only when distributed?
- Does it have controlled foreign company rules that tax you on a C-Corp's retained profit?
- Is there a tax treaty with the US that cuts dividend withholding?
- Do you need central bank or regulator approval to hold shares in a foreign company? India's overseas investment rules are one example.
Common mistakes
- Forming an LLC for a venture-backed startup, then paying for a conversion months later.
- Forming a C-Corp for a lifestyle business, then paying 21% corporate tax plus dividend withholding on profit you always intended to take out.
- Skipping corporate formalities such as issuing shares and signing founder stock agreements, which causes due diligence problems later.
- Ignoring the 83(b) election window of 30 days after receiving restricted stock, where it applies to US taxpayers.
This is general information, not tax or legal advice. A CPA or attorney should confirm the right choice for your facts.
Two federal rates that shape the choice
A C-Corp pays a flat federal income tax on its profit. When it later pays dividends to a foreign owner, the default withholding is 30%, which a tax treaty may reduce. Ask a CPA to model your own numbers.
| Rate | Percent |
|---|---|
| Corporate income tax on profit | 21% |
| Default withholding on dividends to a foreign owner, before any treaty | 30% |
Frequently asked questions
Can a non-US person own a C-Corp?
Yes. There is no citizenship or residence requirement for shareholders or directors of a C-Corp. The restriction you may have heard about applies to S corporations, which cannot have nonresident alien shareholders.
Is a C-Corp more expensive to run than an LLC?
Usually yes. Federal returns are longer, state franchise taxes can be higher, and corporate records need more upkeep. The difference is modest compared with the cost of converting later if you do need a corporation.
Can an LLC raise money from angels?
Yes, some angels will invest in an LLC, often through a convertible note or by becoming members. Institutional funds rarely do. If you expect a priced round, plan for a C-Corp.
Does a C-Corp protect me better than an LLC?
Liability protection is broadly similar when each is run properly. The differences are tax, fundraising and governance, not the strength of the shield.
Which state should a C-Corp use?
Delaware is the default for venture-backed startups because investors and their lawyers know its corporate law. For a C-Corp that will not raise money, other states can cost less each year.
