LLC vs Corporation: Tax Implications for Foreign Owners

The short answer

A single-member LLC is disregarded for federal income tax, a multi-member LLC is a partnership by default, and either can elect to be taxed as a corporation.
A C corporation pays federal income tax at 21%. Dividends paid to foreign shareholders are generally subject to 30% withholding, unless a treaty lowers the rate.
An S corporation cannot have nonresident alien shareholders, may have no more than 100 shareholders and only one class of stock.
Nonresident aliens are not subject to U.S. self-employment tax, unless a social security agreement covers them under the U.S. system.
A foreign-owned single-member LLC files Form 5472 with a pro forma Form 1120 when it has reportable transactions. The penalty for not filing starts at $25,000.

Frequently asked questions

The choice between an LLC and a corporation decides how your U.S. company is taxed, who can own it, how profits reach you and what you file every year. For founders who live abroad, some of the usual advice written for U.S. residents does not apply at all.

This guide compares the options from the point of view of a non-resident owner. For the full picture of federal and state taxes, see our guide to U.S. business taxes for non-resident owners.

The options at a glance

	Single-member LLC	Multi-member LLC	C corporation	S corporation
Federal tax treatment	Disregarded	Partnership	Separate taxpayer, 21%	Pass-through
Who pays federal income tax	The owner, if the income is taxable to them	The members, if the income is taxable to them	The corporation, then shareholders on dividends	The shareholders
Main yearly federal return	Form 5472 with pro forma 1120, for foreign owners with reportable transactions	Form 1065	Form 1120	Form 1120-S
Available to non-resident owners	Yes	Yes	Yes	No

Both types of LLC can elect to be taxed as a corporation instead.

LLC: flexible by default

For federal income tax, an LLC’s classification depends on its members:

One member: the LLC is disregarded. It pays no federal income tax itself, and its income belongs to the owner.
Two or more members: the LLC is classified as a partnership by default. It files Form 1065 and gives each member a Schedule K-1.

The operating agreement can divide profits in ways that differ from ownership percentages, within the limits of the tax rules. That flexibility helps when partners contribute different amounts of money, time or expertise.

For a foreign owner, a pass-through LLC does not mean automatic U.S. tax. A foreign person pays U.S. income tax on income effectively connected with a U.S. trade or business, at the graduated rates that apply to U.S. taxpayers. Whether your LLC’s income falls in that category depends on where and how the business operates.

A foreign-owned single-member LLC also has a reporting duty that U.S.-owned LLCs do not have: Form 5472 with a pro forma Form 1120, whenever it has reportable transactions with its owner. The penalty for not filing is $25,000, with additional penalties if the failure continues after an IRS notice. See our guide on inactive LLC tax returns for what counts.

C corporation: a separate taxpayer

A C corporation pays federal income tax on its own profits at 21% of taxable income, and files Form 1120 every year, even without income.

When it distributes profits as dividends to a foreign shareholder, the dividends are generally subject to 30% U.S. withholding, unless a tax treaty lowers the rate. Your country of residence may also tax the dividends. This is the double taxation usually associated with corporations.

A corporation can also retain profits for reinvestment. Corporations can issue different classes of stock, which is one reason investors and venture funds usually prefer them, often in Delaware. If raising outside capital is part of your plan, that matters as much as the tax rate.

S corporation: not an option for most non-residents

The S corporation is a tax status that lets income pass through to shareholders without corporate tax. It has strict eligibility rules:

No nonresident alien shareholders.
No more than 100 shareholders.
Only one class of stock.

A single nonresident alien shareholder makes the election unavailable. If you live outside the United States and are not a U.S. resident for tax purposes, the S corporation is not a realistic choice.

Self-employment tax

Much U.S. advice about LLCs warns about self-employment tax: 15.3% for Social Security and Medicare on the owner’s earnings. For foreign owners, the rule is different. Nonresident aliens are not subject to self-employment tax, unless an international social security agreement covers them under the U.S. system.

This is one of the clearest cases where advice written for U.S. residents does not fit a founder abroad.

State taxes

States add their own layer, and forming a company in a state without corporate income tax does not remove state obligations elsewhere. If the company does business in another state, it may have to register and pay taxes there too. Annual state taxes also apply regardless of profit: California charges LLCs $800 a year, and Delaware charges LLCs $400 a year from the 2026 tax year. Our guide to the best state to incorporate compares the main options.

Changing later

An LLC can later elect corporate tax treatment, or convert into a corporation under state law. Both are possible, but changing structure can have tax consequences, especially once the company holds assets or has several owners. Deciding before formation is usually cheaper than changing afterwards. If you plan to bring in a partner, see how to add a member to an LLC.

Which one fits you?

Single-member LLC: simple, low maintenance, suited to service businesses and online activities run by one founder. Watch Form 5472 every year.
Multi-member LLC: the same flexibility for partners, with partnership returns and, if the income is effectively connected with a U.S. business, withholding on foreign partners.
C corporation: suited to companies that plan to reinvest profits or raise money from investors. Profits are taxed at 21%, and dividends to foreign shareholders are generally subject to withholding.

The right answer depends on where you live, where the income is earned, the tax treaty between your country and the United States, and your plans for the company. Review the choice with a tax professional who knows both systems.

Frequently asked questions

Is an LLC or a corporation better for a non-resident?

It depends on the business. An LLC is simpler and avoids corporate-level tax, but its owner may still owe U.S. tax on effectively connected income. A C corporation pays 21% and suits companies that reinvest or raise capital.

Can a non-resident own an S corporation?

No. An S corporation cannot have nonresident alien shareholders.

Do foreign LLC owners pay self-employment tax?

Generally no. Nonresident aliens are not subject to U.S. self-employment tax, unless a social security agreement covers them under the U.S. system.

What is double taxation?

A C corporation pays tax on its profits, and shareholders pay tax again when profits are distributed as dividends. For a foreign shareholder, dividends are generally subject to 30% U.S. withholding unless a treaty lowers the rate.

Does a foreign owner need an ITIN for the LLC’s Form 5472?

Not necessarily. For a foreign-owned single-member LLC, Form 5472 asks for the foreign owner’s foreign taxpayer identification number, if any, and a U.S. identifying number or a reference ID. An ITIN becomes necessary in other cases, for example when the owner files a personal U.S. return.
