LLC Tax for US Nonresidents: A Full Guide

Non-US residents can legally own and operate a US business, and the limited liability company (LLC) is one of the most popular structures for doing so. But how an LLC is taxed depends heavily on who owns it, how it’s classified, and where its income comes from, and the rules for a non-resident LLC differ from those for US owners in important ways.

This guide breaks down non-resident LLC taxation from the ground up: who counts as a nonresident alien, how an LLC for non-US residents is classified, the tax that applies to each classification, and what you’ll need to file.

Because state rules and treaty benefits vary, nonresident owners should confirm their specific situation with a tax professional.

LLC Tax for US Nonresidents: Key Takeaways

• A nonresident alien is a non-US citizen who has not obtained a green card or met the substantial presence test. A nonresident alien can own or form a US LLC.
• By default, a foreign-owned single-member LLC is disregarded for federal income tax purposes, while a multi-member LLC is generally treated as a partnership. Although these entities generally do not pay federal income tax as separate taxable entities, a partnership with foreign partners may be required to withhold and pay tax under Section 1446 on effectively connected taxable income allocable to those partners.
• An LLC that elects C corporation treatment pays 21% corporate tax, and dividends to non-resident shareholders face a 30% withholding (often reduced by treaty).

Who is Considered a Nonresident Alien in the US?

A nonresident alien is an individual who does not hold U.S. citizenship and has not satisfied the green card test or the substantial presence test (SPT).

If a foreign citizen meets either test, they are instead classified as a U.S. resident alien. This distinction drives nearly every part of LLC non-resident tax treatment, so it’s the right place to start.

Green Card Test

You are regarded as a resident alien if U.S. immigration law has granted you permission to live permanently in the country as an immigrant. A Permanent Resident Card (Form I-551, the “green card”) is issued to individuals who meet the requirements for this status through U.S. Citizenship and Immigration Services (USCIS). If you pass the green card test at any point in the calendar year but fail the SPT for that year, your residency begins on the first day you are present in the US as a lawful permanent resident.

The status remains valid until you voluntarily renounce it or the U.S. government revokes it.

Substantial Presence Test

The SPT looks at the number of days a foreign individual has been physically present in the US over a defined period. Two parts must both be met before a non-US citizen is treated as a resident alien:

• Part 1: You must be physically present in the US for at least 31 days during the current year, and
• Part 2: You must be present for at least 183 days across a three-year window (the current year plus the two years before it), counted as follows:
  • All the days you were present in the current year, plus
  • 1/3 of the days you were present in the first year before the current year, plus
  • 1/6 of the days you were present in the second year before the current year

Each day of current-year presence counts as a full day; days in the prior two years count as one-third and one-sixth of a day, respectively. If the weighted total reaches 183, you meet the test.

Can a Nonresident Alien Own or Establish an LLC?

Yes. A nonresident alien can establish or own a US limited liability company, because neither residency nor citizenship is required to start a business here. U.S. citizens, corporations, other LLCs, and foreign persons, including nonresident aliens, can all be members of an LLC.

The one exception: an LLC taxed as an S-corporation cannot have nonresident alien members. This is why a US LLC for non-residents almost always ends up taxed as a disregarded entity, a partnership, or a C-corporation rather than an S-corp.

What is an LLC (Limited Liability Company)?

The IRS defines an LLC as a company organized under a state’s limited liability company statute. Both individuals and entities can be members. Like corporate shareholders, LLC owners have limited personal liability for business debts. Creditors generally cannot reach their personal assets beyond their investment in the company. And like partnerships, LLCs offer management flexibility and pass-through taxation.

By default, LLCs are pass-through entities and are not subject to federal income tax at the entity level.

Instead, profits and losses flow directly to the members, who report their share on their own returns. LLCs also have flexibility in how they elect to be taxed, which is where non-resident LLC taxation gets interesting.

Types of Limited Liability Companies

An LLC can have one or more members, with no upper limit. An LLC with one member is a single-member LLC. An LLC with two or more members is a multi-member LLC.

Single-Member LLC

The IRS treats a single-member LLC (SMLLC) as a “disregarded entity,” meaning it is not considered separate from its owner. For federal tax purposes, the IRS effectively “ignores” the LLC and taxes it the same way the owner is taxed.

Multi-Member LLC

A multi-member LLC (MMLLC) has two or more members, with no cap on the number, unless the LLC elects S-corporation treatment, which limits ownership to 100 members. Because nonresident aliens cannot be S-corp shareholders, a foreign-owned MMLLC is taxed as a partnership by default.

Tax Classification of LLCs

LLC members can generally choose the entity’s federal income tax status. Based on the election filed and the number of members, the IRS will treat an LLC as a disregarded entity, a partnership, an S-corporation, or a C-corporation.

Default Tax Classification

• A single-member LLC wholly owned by a nonresident alien is treated as a disregarded entity. A FODE cannot elect S-corporation status, which is available only to US persons.
• A foreign-owned multi-member LLC is treated as a partnership for federal income tax purposes.

By default, both SMLLCs and MMLLCs are pass-through entities and are therefore exempt from entity-level federal income tax, while providing the same limited liability protection to their owners.

Alternative Tax Classification (S-Corp vs. C-Corp Election)

• S-Corporation. By filing Form 2553, an LLC with no more than 100 members may elect S-corporation treatment. However, nonresident aliens cannot own S-corporations, so LLCs with foreign members cannot make this election.
• C-Corporation. To elect C-corporation treatment, file Form 8832, Entity Classification Election.

Tax Implications for Nonresident LLC Owners

LLC taxes for nonresidents depend entirely on the entity’s classification. Below is how federal income tax applies to each of the three structures available to foreign owners.

Nonresident Owner of a Foreign-Owned Single-Member LLC (FODE)

A single-member LLC is a “disregarded entity,” so it isn’t treated as separate from its owner. Its income, gains, losses, and deductions pass through directly to you and are reported on your personal return — the LLC’s income is your income, and you’re responsible for the federal tax on it.

As a nonresident alien, you’re taxed only on US-source income or income effectively connected with a US trade or business (ETBUS). You’re generally engaged in a US trade or business when you (directly or through a dependent agent) carry on “considerable, continuous, and regular” activity in the US to earn a profit — for example, an LLC selling handcrafted furniture from a leased Austin showroom with a US employee filling orders year-round, as opposed to a single isolated sale made from abroad with no US presence.

Dropshipping and other e-commerce models: Whether a US dropshipping or online store creates ETBUS is fact-specific. Run entirely from abroad, with independent third-party suppliers and no US office, staff, or dependent agent, your income may not be effectively connected. Add US-based staff, a warehouse, or a fulfillment operation you control, and the analysis can flip — so confirm your status with a tax professional before filing.

Effectively connected income (reported on page one of Form 1040-NR), less allowable deductions, is taxed at the same progressive rates that apply to US citizens. Non-residents cannot claim the standard deduction or most tax credits.

Federal Tax Brackets and LLC Tax Rates for Nonresident Aliens

There isn’t a separate LLC tax rate for pass-through entities because the income flows to you., Your effectively connected income is taxed using the individual federal tax brackets.

Nonresident aliens filing Form 1040-NR generally use the single or married filing separately schedule (they cannot file jointly or as head of household). The federal individual income tax brackets for tax year 2026 are as follows:

Source: IRS Revenue Procedure 2025-32 (tax year 2026 inflation adjustments).

Nonresident aliens face two different rates: one for effectively connected income (ECI) and another for fixed, determinable, annual, or periodic (FDAP) income that is not effectively connected. Unless a tax treaty sets a different rate, FDAP income (reported on Schedule NEC, page 4 of Form 1040-NR) is subject to a flat 30% tax.

Nonresident aliens use Form 1040-NR to report US-source income and may use one of three filing statuses: single, married filing separately, or qualifying surviving spouse. You cannot file as head of household or married filing jointly. Foreign-source income is generally not subject to U.S. federal income tax for a nonresident alien unless the income is treated as effectively connected with a U.S. trade or business under the applicable sourcing and ECI rules.

To learn more about FODEs, see our guide to filing taxes for foreign-owned U.S. disregarded entities.

Nonresident Owners of a Multi-Member LLC

By default, foreign-owned MMLLCs are treated as partnerships. Like a FODE, a foreign-owned MMLLC is a pass-through entity: it pays no federal tax at the entity level, and each member reports their pro-rata share of income, gains, losses, credits, and deductions (shown on Schedule K-1) on their own return.

A non-resident owner of an MMLLC is generally taxed on the owner’s distributive share of income connected with a U.S. trade or business. If the LLC earns income from a source outside the US, the owners and members owe no US income tax on it unless the income is treated as effectively connected with a U.S. trade or business under the applicable sourcing and ECI rules. Although it isn’t subject to federal tax itself, a foreign-owned MMLLC must file Form 1065, U.S. Return of Partnership Income, and issue each partner a Schedule K-1, and may be required to withhold tax under Section 1446 on effectively connected taxable income allocable to foreign partners.

Nonresident Owners of an LLC Taxed as a C-Corporation

When an LLC elects C-corporation treatment by filing Form 8832, it must file a corporate return on Form 1120 rather than Form 1065. Its income is taxed first at the entity level and again at the shareholder level when dividends are paid.

A C-corporation pays a flat 21% federal tax on income after allowable deductions and must file annually, whether or not it has taxable income.

Shareholders aren’t taxed until they receive dividends. Dividends paid to non-resident shareholders are US-source income and subject to a 30% withholding on the gross amount, which may be reduced or eliminated under an applicable tax treaty between the US and the shareholder’s home country. To claim a treaty benefit, provide the company with the appropriate withholding certificate and a Form W-8 BEN. A non-resident shareholder must file Form 1040-NR if they have US income for which source withholding didn’t fully satisfy their tax liability, or if they’re claiming a refund of withheld or overpaid tax.

Other Taxes That May Apply

State Income Tax

Like the federal government, most states treat LLCs as pass-through entities by default, so the entity itself is often exempt from filing a state return. Members pay tax on their share of business profits under the state’s individual income tax rules — some states use a flat rate, others a progressive one. An LLC that elects C-corporation treatment, however, must file and pay at the state’s corporate rate, and shareholders may owe state tax on income received from the corporation. For more, see our guide to filing LLC taxes.

Payroll Tax

If a foreign-owned LLC hires employees to perform services in the United States, it generally must withhold and remit applicable federal employment taxes for each employee and file the required payroll tax returns. The employee pays half (deducted from their pay) and the LLC pays the other half: 6.2% for Social Security and 1.45% for Medicare, or 7.65% each, for a combined 15.3% remitted to the federal government.

Sales Tax

Whether goods and services are taxable depends on the state and location of your business. If what your LLC sells is taxable, you must collect and remit sales tax from customers to the appropriate state or local agency. State-level rates vary, and some states also impose local sales taxes. Visit our State Income Tax Guide to learn more.

Filing Requirements for LLCs and Nonresident Owners

Note on Beneficial Ownership Information (BOI): Under a FinCEN interim final rule effective March 26, 2025, entities formed in the United States — including foreign-owned US LLCs — and their beneficial owners are exempt from BOI reporting under the Corporate Transparency Act. Only entities formed under the law of a foreign country that then register to do business in a US state are still required to file. Because most LLCs discussed here are US-formed, BOI reporting generally does not apply. FinCEN has signaled it may finalize this rule, so confirm current requirements before you file.

Trusting Experts to File Your Tax Return

Non-resident LLC taxation involves a lot of moving parts; classification elections, ETBUS analysis, withholding, Form 5472, and state-by-state rules. A single missed form (Form 5472 penalties start at $25,000) can be costly. That’s exactly the kind of thing worth handing to specialists.

Frequently Asked Questions (FAQ)

Can I incorporate a US company if I don’t live in the US?

Yes. The US doesn’t require citizenship or residency to form a company. Non-US residents can open an LLC or corporation in almost any state, though some states add steps for foreign owners. You’ll typically need a registered agent and, in most cases, an EIN.

Should non-US residents use an LLC or a corporation for a US business?

It depends. An LLC offers pass-through taxation and simpler compliance, while a C-corp may suit founders raising investment or retaining profits. Non-resident aliens can’t elect S-corp status. The right choice hinges on your goals, income type, and home-country tax treaty.

Under a U.S. treaty, what must a non-resident corporation create in the United States before it is subject to U.S. taxation on its business profits?

A permanent establishment (PE). Under most US tax treaties, a non-resident corporation’s business profits are taxed in the US only if it operates through a PE — a fixed place of business such as an office, branch, or dependent agent — located in the United States.
