Understanding U.S. tax obligations can be challenging for foreign-owned LLCs. Many foreign business owners find themselves confused by terms like “effectively connected income,” “FDAP income,” and “economic nexus.” The complexities of intercompany transactions, especially when multiple entities are involved across different jurisdictions, only add to the confusion.
In this article, we present the key concepts of U.S. tax compliance for foreign-owned LLCs in a dialogue format between a client and a CPA. This conversational style will help clarify these complex tax rules and make them more accessible. By the end of this article, you’ll have a better understanding of how to manage your U.S.-based LLC while staying compliant with U.S. tax regulations.
Client: Hi, I run a U.K.-based business, and I also have a U.S. LLC. I’m confused about how my U.S. LLC is taxed. Could you help me understand?
CPA: Absolutely! The tax treatment of your U.S. LLC depends on whether it’s a single-member LLC or a multi-member LLC. Generally, LLCs are “pass-through” entities, meaning the LLC itself doesn’t pay federal income taxes. Instead, the income passes through to you as the owner, and you report it on your personal or corporate tax returns unless you’ve elected to treat it as a corporation by filing IRS Form 8832.
Client: My LLC is a single-member LLC. I also have related party transactions with my U.K. company. How does that impact my tax obligations?
CPA: Since your LLC is a single-member entity, it’s considered a disregarded entity for tax purposes. However, because of your related party transactions with your U.K. company, you’ll need to file a pro forma IRS Form 1120 along with Form 5472. This is an Information Return for Foreign-Owned U.S. Corporations. No federal taxes are due unless your LLC has effectively connected income (ECI) or U.S.-sourced FDAP income where withholding wasn’t properly done.
Client: What exactly is “effectively connected income” or ECI?
CPA: Effectively connected income, or ECI, refers to income that comes from a U.S. trade or business. If your LLC is actively engaged in business in the U.S. and generates income from those activities, that income is considered ECI. It’s generally taxable unless a tax treaty applies to reduce or eliminate the tax liability. If you have ECI, you’ll need to report it on Form 1040-NR (if you’re filing as an individual) or Form 1120-F (if it’s owned by a foreign corporation).
Client: And what about FDAP income? How does that differ from ECI?
CPA: FDAP income refers to passive income—things like dividends, interest, rents, and royalties—that’s U.S.-sourced. Unlike ECI, FDAP income doesn’t come from active business operations. Instead, it’s subject to a flat 30% withholding tax, unless a tax treaty reduces the rate. If the FDAP income wasn’t properly withheld at the source, you’ll need to report it on Form 1040-NR or Form 1120-F and pay the appropriate taxes.
Client: That makes sense. But I’ve also heard the term “economic nexus.” What’s that, and does it apply to me?
CPA: Economic nexus is a concept related to state sales tax. It applies when your business has enough of a connection to a state that the state requires you to register and collect sales tax, even if you don’t have a physical presence there. For instance, if your LLC sells more than $500,000 worth of goods in a state like California, you may need to collect and remit sales tax for that state, even if you don’t have an office or warehouse there.
Just remember, economic nexus is separate from ECI. Economic nexus applies to state sales tax, while ECI applies to federal income tax on business income.
Client: Got it! That’s helpful to know. But do I need an ITIN for this?
CPA: You’d only need an ITIN (Individual Taxpayer Identification Number) if your LLC has ECI or improperly withheld FDAP income. If your LLC’s income is not effectively connected to a U.S. trade or business, you can file the necessary forms without an ITIN, i.e. proforma 1120 and 5472. You’ll just indicate your foreign status when filing.
Client: Alright. Now, I want to discuss the relationship between my U.K. company and my U.S. LLC. The U.K. company handles most of the operations, like buying inventory from China. But the U.S. LLC collects payments from U.S. customers. How should I handle the funds that flow between the two?
CPA: Let me break it down for you. In this case, it sounds like your U.S. LLC is mainly acting as a conduit for collecting funds on behalf of the U.K. company. The U.K. company is the one conducting the real business activities—purchasing inventory, managing supplier relationships, and overseeing logistics—while the U.S. LLC is only receiving and holding funds from U.S. customers.
Since the U.S. LLC isn’t engaging in significant business activities, it’s more like the LLC holding the funds on behalf of the U.K. entity. Any revenue collected by the U.S. LLC should be recorded as a liability payable to the U.K. company. When the U.S. LLC disburses funds—such as paying suppliers or transferring money to the U.K. company—the liability gets reduced accordingly.
Client: So, I shouldn’t record the payments as income for the U.S. LLC?
CPA: Exactly. The U.S. LLC isn’t generating its own income. It’s simply collecting and holding the money on behalf of the U.K. company. This means the U.S. LLC should treat all incoming funds as liabilities owed to the U.K. entity.
Client: That’s a huge relief! Thanks for clearing that up. What should I do next to ensure I stay compliant with U.S. tax regulations?
CPA: First, make sure you’re using reliable accounting software to track all income, expenses, and liabilities between the U.K. company and the U.S. LLC. You’ll also need to file the necessary forms—such as Proforma Form 1120 and Form 5472 for your U.S. SMLLC. If your business exceeds economic nexus thresholds in a state, you’ll need to register and collect sales tax there.
Finally, since this setup involves multiple jurisdictions, it’s a good idea to consult with a tax professional regularly – within the affected jurisdictions. They can help you navigate any changes in tax law and ensure you stay compliant with both U.S. and international regulations.
