What Happens When One LLC Member Is American and the Other Is a Non-US Resident?
When one LLC member is a U.S. person and the other is a non-US resident, the LLC can generally operate normally, but the foreign owner's status creates additional U.S. tax documentation and potentially withholding requirements.
For a two-member LLC, the first question is how the company is classified for federal tax purposes. A domestic multi-member LLC generally defaults to partnership taxation unless it elects to be treated as a corporation. That means the LLC itself typically files a partnership information return, while its members are taxed according to their respective shares of the partnership's tax items.
The important difference is that the two members are not treated identically for U.S. tax purposes. The American member is a U.S. person; the non-US resident may be a foreign partner subject to special reporting and withholding rules.
How the Ownership Structure Works
Consider this example:
- Alex: U.S. citizen, 60% owner
- Daniel: nonresident foreign individual, 40% owner
- Company: U.S. LLC
- Tax classification: partnership
The LLC generally reports its income and deductions at the partnership level and passes the relevant tax items through to its members. Alex generally provides Form W-9 to the partnership to certify U.S. status. A nonresident foreign individual generally provides Form W-8BEN to establish foreign status for applicable withholding purposes. The IRS specifically identifies Form W-9 for U.S. partners and Form W-8BEN for nonresident alien partners. This documentation matters because the partnership needs to know which member is foreign when determining whether Section 1446 withholding applies.
Does the Foreign Member Make the Whole LLC Foreign-Owned?
No. The LLC remains a domestic U.S. entity if it was formed under U.S. law. Having one foreign member does not convert the entire LLC into a foreign company. Instead, the partnership has one U.S. partner and one foreign partner.
That distinction is important because Section 1446 withholding applies to the foreign partner's allocable share of applicable effectively connected taxable income—not automatically to the American member's share.
The IRS states that a partnership must determine whether each partner is a foreign partner and that withholding is based on effectively connected taxable income allocable to foreign partners.
What Happens to the LLC's Tax Return?
If the LLC is taxed as a partnership, it generally files Form 1065, U.S. Return of Partnership Income, subject to applicable exceptions. The partnership reports its income, deductions, credits, and other tax items and generally provides each member with a Schedule K-1.
The American member receives a K-1 reflecting their share of the partnership's tax items. The foreign member generally receives a K-1 as well, but additional international reporting and withholding considerations may apply. This means the presence of a foreign member doesn't eliminate ordinary partnership reporting. It adds another layer of compliance.
When Does Section 1446 Withholding Apply?
This is usually the most important tax issue in a mixed U.S.-foreign LLC. Under IRC Section 1446(a), a partnership with income effectively connected with a U.S. trade or business generally must withhold tax on the portion of its effectively connected taxable income allocated to foreign partners. The partnership has to make the withholding payments even if it does not distribute cash to the foreign member. For example, suppose the LLC earns $200,000 of ECTI and ownership is:
- U.S. member: 60%
- Foreign member: 40%
The foreign member's starting share would be $80,000 before considering the applicable partnership-level calculations and adjustments. If Section 1446 applies, the withholding obligation is associated with the foreign member's allocable ECTI—not the entire $200,000. The U.S. member's share is not subject to Section 1446 foreign-partner withholding simply because the other member is foreign.
Does the Foreign Member Need an ITIN?
Not necessarily at the moment the LLC is formed. A foreign individual who is not eligible for an SSN may need an ITIN when a U.S. tax identification number is required for a particular federal tax purpose. The existence of a foreign member does not mean an ITIN is automatically required in every situation.
However, foreign partners should not ignore the issue. Partnership reporting can require identifying information, and the IRS has procedures for situations involving foreign partners who do not have U.S. TINs and are not required to obtain them.
The practical question is therefore not simply, "Does the foreign owner have an ITIN?" It is: Does this foreign partner have a U.S. tax identification requirement based on the LLC's reporting and tax circumstances? That distinction can prevent unnecessary applications while avoiding a missing-TIN problem when one is actually required.
What Forms Will Each Member Provide?
A simple starting framework looks like this:
| Member | Typical status | Typical documentation |
|---|---|---|
| U.S. individual | U.S. person | Form W-9 |
| Nonresident individual | Foreign person | Form W-8BEN |
| LLC taxed as partnership | Domestic partnership | Form 1065 |
| Foreign partner receiving applicable ECTI | Foreign partner | Potential Section 1446 withholding/reporting |
The IRS says a partnership can generally rely on Form W-9 to establish that a partner is a U.S. person and use appropriate W-8 documentation to establish foreign status.
What About Form 8804, 8805, and 8813?
If Section 1446 withholding applies, the LLC may have several additional compliance responsibilities. Form 8813 is used for Section 1446 withholding tax payments during the year. Form 8804 reports the partnership's annual Section 1446 withholding tax liability. Form 8805 provides the applicable foreign partner with information about the partner's effectively connected income and withholding credit.
The IRS specifically identifies these forms as part of the reporting and payment process for partnerships with foreign partners. This is an area where a mixed-ownership LLC can become considerably more complicated than a domestic-only two-member LLC.
Does the Foreign Member Automatically Owe U.S. Income Tax?
No. Foreign residency alone does not mean the foreign member automatically owes U.S. federal income tax on every dollar allocated by the LLC. The analysis depends on factors including:
- Whether the partnership conducts a U.S. trade or business
- The type and source of the partnership's income
- Whether the income is effectively connected with that U.S. business
- The foreign member's circumstances
- Applicable tax treaties
- Deductions and other adjustments
Importantly, Section 1446 withholding is not necessarily the foreign partner's final tax liability. It is a withholding mechanism that operates during the year. The foreign partner may use applicable withholding documentation, such as Form 8805, when determining the credit available on a U.S. tax return.
What If the LLC Makes No Distributions?
The foreign member's withholding obligation cannot simply be avoided by leaving profits inside the company. For a partnership that is not a publicly traded partnership, Section 1446 withholding generally applies in the year ECTI is allocated to the foreign partner, whether or not the partnership actually distributes that income.
This is an important distinction for startups that retain profits for working capital. A company can therefore have a cash-flow issue: the partnership may need to fund withholding payments even though the foreign member has not received an equivalent cash distribution.
What Should the Two Members Do?
A mixed U.S.-foreign LLC should establish its compliance structure before the first tax filing.
Practical checklist
- Confirm the LLC's federal tax classification.
- Document each member's U.S. or foreign status.
- Have the American member provide the appropriate Form W-9.
- Have the foreign member provide the appropriate Form W-8BEN, where applicable.
- Determine whether the LLC conducts a U.S. trade or business.
- Determine whether the partnership generates ECTI allocable to the foreign member.
- Check whether Section 1446 withholding applies.
- Track Forms 1065, K-1, 8804, 8805, and 8813 as applicable.
- Determine whether the foreign member needs an ITIN or another U.S. tax identification number.
- Review the foreign owner's home-country tax obligations separately.
For founders using a U.S. LLC to combine American and international ownership, platforms such as Foundeck—an AI-powered U.S. company formation and management platform for global founders—can be useful for understanding the entity and administrative side. Tax classification and cross-border withholding, however, deserve careful attention from a qualified tax professional.
Frequently Asked Questions
Can a U.S. citizen and foreigner own the same LLC?
Yes. A U.S. person and a non-US resident can generally be members of the same U.S. LLC. The foreign member's status creates additional tax documentation and potentially withholding requirements.
Does the foreign member have to become a U.S. resident?
No. Owning an LLC does not, by itself, make a foreign member a U.S. resident.
Does the American member have to pay tax on the foreign member's share?
Generally, each partner is responsible for the tax consequences of their own distributive share, subject to the partnership's reporting and applicable tax rules. The foreign member's status does not automatically transfer their tax liability to the U.S. member.
Does a mixed-ownership LLC have to file Form 1065?
If the LLC is classified as a domestic partnership, it generally files Form 1065, subject to applicable exceptions. Having one foreign member does not remove the partnership filing requirement.
Does the foreign member need a W-9?
Generally no. A nonresident foreign individual generally uses the appropriate W-8 documentation rather than Form W-9 to certify foreign status.
Can the foreign member receive a Schedule K-1?
Yes. A foreign partner can receive a Schedule K-1 reporting the partner's share of partnership tax items. Additional international reporting can apply.
Does the LLC have to withhold tax from the American member?
Section 1446 is specifically concerned with the foreign partner's allocable ECTI. A validly documented U.S. partner is not treated as a foreign partner for this purpose.
What happens if the foreign member sells their LLC interest?
A different rule, Section 1446(f), can apply to certain transfers of partnership interests by foreign persons. In qualifying circumstances, the transferee may have a withholding obligation based on the amount realized.
Conclusion
Having one American member and one non-US resident member does not prevent an LLC from operating as a normal U.S. business. The key difference is that the foreign member introduces cross-border tax documentation and potentially Section 1446 withholding into the partnership's compliance obligations. The cleanest way to think about the structure is simple: the LLC is one entity, but its members can have very different U.S. tax profiles.
The American member generally documents U.S. status with Form W-9. The foreign member generally establishes foreign status with the appropriate W-8 form. If the partnership generates effectively connected taxable income for the foreign member, Section 1446 can require withholding even when no cash is distributed.
For entrepreneurs combining U.S. and international ownership, getting that distinction right from the beginning can make the difference between a straightforward partnership structure and a costly tax-compliance problem later.
