A limited liability company formed in a US state can be owned by someone who has never lived in the country, and many software, consulting and e-commerce founders in Hyderabad, Calgary and Toronto use one. The tax answer depends on how many owners the LLC has, where the work is performed and what the LLC elects. This guide to foreign-owned LLC US tax and reporting explains the default classification, the annual IRS forms that apply even when the LLC owes no tax, and what the owners report at home. It uses 2025 return rules and October 2026 guidance.
Foreign-owned LLC US tax and reporting: how is it classified?
| Ownership | Default classification | What the LLC files | What the owner reports |
|---|---|---|---|
| One foreign individual or company | Disregarded entity | Pro forma Form 1120 with Form 5472 | US income only if there is effectively connected or US-source income |
| Two or more owners | Partnership | Form 1065 and Schedules K-1 | Each owner reports a share, and withholding applies to foreign partners |
| Any number, with Form 8832 election | Corporation | Form 1120 and Form 5472 | Dividends are taxed with withholding |
A change to the classification is made on Form 8832; S corporation status is not available because nonresident aliens cannot be S corporation shareholders. The election can take effect no more than 75 days before it is filed or 12 months after, and a later change is generally blocked for 60 months.
When does the owner owe US income tax?
A foreign owner of a disregarded LLC is taxed in the US as if the owner operated directly, so the question is whether the income is US-source or effectively connected with a US trade or business.
- Work done outside the US: pay to a nonresident alien for services performed outside the United States is not treated as wages and is not subject to US withholding, and income from services done abroad is generally not US-source.
- Work done in the US: compensation for services performed in the US by a nonresident alien is generally subject to US tax, and a US trade or business can create a filing obligation even if a treaty reduces the tax.
- Treaty relief: the US-India and US-Canada treaties can limit tax on business profits where there is no permanent establishment, but claiming a treaty usually requires a return and sometimes Form 8833.
Our guide to US tax for nonresidents explains the distinction between FDAP income and effectively connected income.
What does the LLC file every year?
For a foreign-owned disregarded LLC, the IRS treats the entity as a separate corporation for the limited purpose of Form 5472. The LLC must file a pro forma Form 1120, completing only the name, address and certain items, with Form 5472 attached, by the due date including extensions. The tax year is the owner's, or the calendar year if the owner has none. Reportable transactions include amounts connected with the formation, dissolution, acquisition and disposition of the entity, including contributions to it and distributions from it, and transactions listed for the usual related-party categories.
- Collect the numbers. List contributions, distributions, loans, fees and reimbursements with the owner and related parties for the year.
- Prepare Form 5472 for each related party. For the owner, give a US identifying number if one exists (an SSN or ITIN for an individual, an EIN for an entity). If none exists, enter a reference ID number you assign, alphanumeric up to 50 characters and used consistently from year to year.
- Complete the pro forma Form 1120. Write "Foreign-owned U.S. DE" across the top.
- File on paper. A foreign-owned disregarded entity cannot e-file Form 5472; the instructions give a dedicated fax number and Ogden mailing address.
- Extend only if needed. Use Form 7004 and send it to the dedicated address by the original due date.
A calendar-year LLC's due date is the 15th day of the 4th month after year-end, which was April 15, 2026 for 2025; with Form 7004 the extended date is generally six months later. The subsidiary guide sets out Form 5472 in more detail.
Partnerships with foreign members
A multi-member LLC files Form 1065 and issues Schedule K-1 to each partner; partners are not employees and do not receive Form W-2. Where a foreign partner is allocated effectively connected income, the partnership must withhold tax on that share, reported on Forms 8804 and 8805 rather than Form 1042. The IRS partnership page also lists Schedules K-2 and K-3 for international items. A partner with US-source or effectively connected income needs a US taxpayer number and generally files his or her own US return; see SSN and ITIN.
State and other filings
- EIN: the LLC needs its own EIN; a foreign founder applies by phone, fax or mail on Form SS-4. See EIN and bank account.
- Beneficial ownership reports: FinCEN's final rule effective August 14, 2026 exempts US-formed companies, so a US LLC generally files no BOI report. See the BOI status update.
- Illinois: annual reports, a registered agent and state tax registrations still apply; see Illinois annual report and registered agent and LLC vs corporation.
- Home country: Canadian owners should have their CPA review how Canada classifies the LLC and whether foreign property or affiliate reports apply (see T1135). Indian resident owners should confirm the overseas investment route and disclosure of foreign assets with their Chartered Accountant (Schedule FA).
Documents and information you need
- Articles of organization, operating agreement and EIN notice
- Owner identification, residence and tax ID numbers (if any)
- Ledger of contributions, distributions, loans and fees with the owner
- Contracts showing where services are performed and who the customers are
- Bank statements and records for 5472 support
A worked example
Ravi lives in Hyderabad and owns 100% of an Illinois single-member LLC that builds software for US clients. In 2025 he contributed US$15,000 and took distributions of US$40,000, and all development work was done in Hyderabad. Because the services were performed outside the United States, the LLC has no US wage withholding and generally no US-source income, but it still files a pro forma Form 1120 with Form 5472 reporting the contribution and distribution, by April 15, 2026 or by extension. If Ravi instead spent three months working on-site in Naperville, that work would be US-source and likely effectively connected, so he would need a US return, an ITIN and a treaty review. All figures are hypothetical.
Mistakes to avoid
- Believing that no US income tax means no US filing; Form 5472 is separate.
- E-filing or mailing a disregarded entity's Form 5472 to the standard corporate address.
- Treating the LLC's profit as the owner's income at home without checking the home-country classification.
- Skipping reporting for contributions and distributions because "it is my own money".
- Forgetting an ITIN for an owner who must file a US return.

Frequently asked questions
Does my foreign-owned LLC pay US income tax?
Only if there is US-source or effectively connected income taxable to the owner or the LLC. It may still have to file Form 5472.
Do I need an ITIN?
If the owner must file a US return or claim a treaty benefit, an ITIN or SSN is needed. For Form 5472 alone, a reference ID number can be used.
Can a foreign-owned LLC elect S corporation status?
No. An S corporation cannot have a nonresident alien shareholder.
What is the penalty for missing Form 5472?
$25,000 per form, with additional penalties of $25,000 for each 30-day period that the failure continues after 90 days from an IRS notice.
Do I file Form 5472 if the LLC had no activity?
If there were no reportable transactions, the instructions say the form is generally not required; contributions or distributions count, so check the year's bank activity first.
