How do they compare for a foreign founder?
| Single-member LLC (default) | C corporation, or LLC taxed as one | |
|---|---|---|
| Who is the US taxpayer | You, on income effectively connected with a US business | The company |
| US tax if all work is done abroad | Generally none | 21% on worldwide profit |
| US tax on money paid to you | None on transfers from the LLC | 30% withholding on dividends, or a treaty rate |
| Federal filings | Form 5472 with a pro forma 1120, and Form 1040-NR if you have US taxable income | Form 1120 every year, Form 5472 if 25% or more foreign-owned, Forms 1042 and 1042-S for dividends |
| Raising investment | Harder | The standard for venture capital |
| Selling shares later | Sale of the business's assets or interests, taxed depending on US connection | Sale of shares, generally not taxed by the US for a foreign seller, with exceptions such as US real property |

When does an LLC suit a foreign founder?
- A service business run from abroad, such as consulting, design or software development.
- An online business with no US staff or office.
- A founder who wants low costs and simple filings, and has no plans for US investors.
The trade-off is that the business's income is yours, so your home country may tax it as it is earned. See whether foreign-owned US LLCs pay US tax.
When does a C corporation suit a foreign founder?
- You plan to raise money from US investors, who generally expect a Delaware C corporation with preferred shares. See Delaware C corp for startups.
- The business has substantial US operations, staff or customers served from the US, so US tax is likely either way.
- You will reinvest most profit, which is taxed once at 21% until paid out.
- You want the company, not you personally, to be the US taxpayer and filer.
A C corporation can pay its non-resident founder a salary. See non-resident salary from a US company.
How does your home country change it?
This is often the deciding factor. Some countries treat a US LLC as transparent and tax you on its profit as earned. Others treat it as a foreign company, sometimes under rules that tax undistributed profits of controlled foreign companies. A C corporation may fall under those rules too. Credit for US tax paid, and the treaty rate on dividends, also vary. Get advice in your country of residence before choosing.
Can you switch later?
An LLC can elect to be taxed as a corporation on Form 8832, and can convert to a corporation under state law, typically when investors arrive. Moving the other way, from a corporation to pass-through treatment, is treated as a liquidation and can be costly. Starting as an LLC and converting later is common. See how LLCs are taxed.
The election is made on Form 8832.
What do both need?
A registered agent, an EIN, a bank account and yearly state filings. Both also file Form 5472 for transactions with foreign owners. S corporation status is not available to foreign owners in either case.

Questions people ask
Should a non-resident choose an LLC or a C corp?
An LLC often suits a business run entirely from abroad with no US investors. A C corporation suits founders raising US venture capital or with substantial US operations.
Does a C corporation owned by a foreigner pay US tax?
Yes. A US C corporation pays 21% federal tax on its worldwide profit, wherever its owner lives.
Is there withholding on dividends to foreign shareholders?
Yes, generally 30%, or a lower rate under a tax treaty.
Can a foreign-owned LLC become a C corporation later?
Yes, by electing corporate tax treatment or converting under state law. Moving back to an LLC can be costly.
