Last Updated: May 2026 | Reading Time: 13 minutes | Verified Against: IRS Publication 519, Form 5472 Instructions, and two CPAs specializing in non-resident taxation
We have filed Form 5472 and Form 1120 for foreign-owned LLCs. We have paid a CPA to review our filings. We have read IRS Publication 519 cover to cover so you do not have to. This guide explains exactly what non-resident LLC owners owe the US government — and what they do not.
⚠️ Not Legal or Tax Advice
LLCBC publishes educational content only. We are not attorneys, CPAs, or financial advisors. Always consult a qualified professional before making legal or tax decisions. Our guides are starting points, not substitutes for personalized professional advice.
The Biggest Misconception: "No US Income = No US Tax"
This is partially true, but dangerously incomplete. A non-resident single-member LLC owner with no US-sourced income and no effectively connected trade or business (ETBUS) in the United States typically owes $0 in US federal income tax.
However, you still have filing obligations. The IRS requires informational returns even when no tax is due. Ignore them, and the penalty is $25,000 per form, per year. This is not a scare tactic. We have seen the IRS assess this penalty against non-resident founders who assumed "zero tax" meant "zero paperwork."
This guide separates tax liability (what you owe) from filing obligations (what you must submit). Understanding the difference keeps your LLC alive and your bank account intact.
Tax Liability vs. Filing Obligations: The Framework
| Scenario | US Federal Income Tax? | Filing Required? | Forms |
|---|---|---|---|
| No US-sourced income, no ETBUS | $0 | Yes | Form 5472 + Form 1120 |
| US-sourced income, no ETBUS | 30% withholding on US-source FDAP income | Yes | Form 1040-NR, Form W-8BEN-E |
| US trade or business (ETBUS) | Graduated rates on net income | Yes | Form 1040-NR + Schedule C |
| Multi-member LLC with US partners | Depends on partnership agreement | Yes | Form 1065 + Schedule K-1 |
Most non-resident readers fall into Scenario 1: They run a digital agency, sell software, or offer consulting to non-US clients through a Wyoming LLC. No US customers. No US office. No US inventory. For them, the US tax bill is zero, but the filing requirement is real.
Scenario 1: The "Zero Tax" Filing (Form 5472 + Form 1120)
If you are a non-resident who owns 25% or more of a US single-member LLC, the IRS classifies your entity as "foreign-owned." This triggers a specific reporting regime.
Form 5472: Information Return of a 25% Foreign-Owned US Corporation
Despite the name saying "Corporation," foreign-owned single-member LLCs must file Form 5472. The form reports:
- Your identity as the foreign owner
- Money or property transferred between you and the LLC
- Loans, payments, or services exchanged between the LLC and related foreign parties
Key rule: Even a $1 transfer between your personal foreign account and the LLC business account must be reported. We report every capital contribution and every owner draw.
Form 1120: US Corporation Income Tax Return
A foreign-owned single-member LLC files Form 1120 as a "shell" return. The LLC itself is a disregarded entity for income tax purposes, but the foreign ownership status forces this informational filing.
On Form 1120, you:
- Check the box for "foreign-owned disregarded entity"
- Attach Form 5472
- Report $0 income if there is no US tax liability
- Sign and date
The $25,000 Penalty
If you fail to file Form 5472 by the deadline, or if you file an incomplete/inaccurate form, the IRS assesses a penalty of $25,000 per form, per year. This applies to both late filing and failure to file.
Real case we verified: A Dubai-based founder formed a Wyoming LLC in 2023, made $0 US income, and ignored Form 5472 for 2023 and 2024. In 2025, the IRS sent a notice assessing $50,000 in penalties ($25,000 x 2 years). He settled for $15,000 after hiring a tax attorney, but the stress and legal fees cost him another $8,000.
Our action: We hired a CPA for $400/year to file Forms 5472 and 1120. It is the cheapest insurance policy we have ever bought.
Deadline and Extensions
- Normal deadline: April 15 (following the calendar year)
- Automatic extension: File Form 7004 by April 15 to extend to October 15
- Our recommendation: File by April 15. Do not rely on extensions unless your CPA specifically requests one.
Scenario 2: US-Sourced Income (FDAP)
FDAP stands for Fixed, Determinable, Annual, or Periodical income. Examples include:
- Royalties from US book sales or music streaming
- Rents from US real estate
- Dividends from US stocks
- Interest from US bonds
- Service fees paid by US clients if the service is performed in the US
FDAP income is taxed at a flat 30% withholding rate unless a tax treaty reduces it. The payer (the US client or platform) usually withholds this at source and remits it to the IRS.
Tax Treaties Can Reduce the 30%
The US has income tax treaties with 60+ countries. These treaties often reduce FDAP withholding from 30% to 10%, 15%, or 0%, depending on the income type and country.
| Country | Typical FDAP Withholding (Treaty Rate) | Form to Claim Treaty Benefit |
|---|---|---|
| United Kingdom | 0% on royalties, 0% on most interest | W-8BEN-E |
| Canada | 0% on royalties, 10% on dividends | W-8BEN-E |
| Germany | 0% on royalties, 0% on interest | W-8BEN-E |
| India | 15% on royalties, 15% on dividends | W-8BEN-E |
| UAE (no treaty) | 30% flat | N/A |
| Saudi Arabia (no treaty) | 30% flat | N/A |
How to claim treaty benefits: Submit Form W-8BEN-E to the US payer (client, platform, or broker). They will withhold at the treaty rate instead of 30%. If they already withheld 30%, you can file Form 1040-NR to claim a refund of the difference.
Scenario 3: Effectively Connected Trade or Business (ETBUS)
This is where tax liability gets serious. If your LLC conducts a trade or business in the US that is "effectively connected" to US income, you pay US tax on the net profit at graduated rates (10% to 37% for individuals, 21% for C-Corps).
What Counts as ETBUS?
The IRS uses a facts-and-circumstances test. Strong indicators include:
- You have employees or dependent agents in the US
- You maintain an office or warehouse in the US
- You regularly negotiate and sign contracts in the US
- You provide personal services inside the US for more than 183 days in a year
What Does NOT Count as ETBUS?
- Selling digital products to US customers from abroad
- Running a website hosted on US servers (Amazon AWS, Cloudflare)
- Using a US payment processor (Stripe, PayPal)
- Having a US LLC with no US physical presence
Our situation: We run LLCBC through a Wyoming LLC. Our writers are in Europe and Asia. Our hosting is US-based but automated. We have no US employees, no US office, and no US travel for business purposes. The IRS does not consider this ETBUS. We file Forms 5472 and 1120 with $0 tax liability.
State Tax Obligations: Wyoming vs. Delaware vs. New Mexico
Federal tax is only half the story. Your state of formation may also want a filing.
| State | State Income Tax on LLC? | Franchise Tax | Annual Report | Total State Obligation |
|---|---|---|---|---|
| Wyoming | None | None | $62/year | $62/year |
| Delaware | None (if not operating in DE) | $300/year | Included in franchise tax | $300/year |
| New Mexico | None (if not operating in NM) | None | $0 | $0/year |
Important distinction: State income tax applies if you physically operate in that state. If you live in Dubai and your LLC is in Wyoming, you do not pay Wyoming income tax because you are not a Wyoming resident and the LLC does not operate there. You pay the $62 annual report and nothing else.
Sales Tax: The Hidden Trap
Many non-resident founders forget about US sales tax. If your LLC sells physical products or certain digital services to customers in US states, you may need to collect and remit sales tax.
Nexus: When You Owe Sales Tax
You have "nexus" (a tax connection) in a state if:
- You have inventory in that state (Amazon FBA, 3PL warehouse)
- You have employees or contractors there
- You exceed economic nexus thresholds (e.g., $100,000 in sales or 200 transactions in a state)
Our experience: We do not sell physical products, so sales tax does not apply to LLCBC. However, if you run an e-commerce store using Shopify and ship from a US warehouse, you likely have nexus in that warehouse state. Use a service like TaxJar or Avalara to track nexus automatically.
Self-Employment Tax: Do Non-Residents Pay It?
No. Self-employment tax (Social Security and Medicare, 15.3%) applies to US residents and certain resident aliens. Non-resident aliens generally do not pay self-employment tax on LLC income, even if the LLC is US-based.
However, if you elect to treat your LLC as a C-Corporation or S-Corporation (rare for non-residents), different payroll tax rules apply. Consult a CPA before making any tax classification election.
Do You Need a CPA? The Honest Answer
| Your Situation | Can You DIY? | CPA Cost (Annual) |
|---|---|---|
| Single-member LLC, $0 US income, only Form 5472/1120 | Maybe — if you are detail-oriented | $300-$500 |
| Single-member LLC, some US clients, treaty benefits | No — W-8BEN-E and treaty claims are technical | $500-$1,000 |
| Multi-member LLC or partnership | No — Form 1065 is complex | $800-$2,000 |
| E-commerce with sales tax nexus in 5+ states | No — use TaxJar + CPA combo | $1,500-$3,000 |
Our recommendation: Even for the simplest scenario, hire a CPA for year one. Watch how they prepare the forms. Ask questions. For year two, you can decide whether to DIY or continue outsourcing. The $400 we pay annually is less than one hour of a good lawyer's time.
How to Find a CPA Who Understands Non-Residents
Most US CPAs rarely encounter foreign-owned disregarded LLCs. Ask these questions before hiring:
- "Do you file Form 5472 for foreign-owned single-member LLCs regularly?" If they pause or ask what Form 5472 is, walk away.
- "Do you understand tax treaty benefits for [your country]?" They should name the treaty article without googling.
- "Can you file without me having an ITIN?" The answer should be yes. The LLC's EIN is sufficient for business filings.
- "What is your fee for Form 5472 + Form 1120?" Get a flat quote, not an hourly estimate.
Where we found our CPA: Through a referral from another non-resident founder in a Facebook group. We interviewed three before choosing. The one we hired had 12 foreign-owned LLC clients and quoted $400 flat for Forms 5472 and 1120.
Annual Compliance Calendar
Print this and pin it to your desk:
| Date | Action | Responsible Party |
|---|---|---|
| January 1 | Review prior year transactions. Compile owner contributions and draws. | You or bookkeeper |
| January 31 | Send 1099s to US contractors (if any) via your CPA | CPA |
| March 1 | Deliver all documents to CPA for Form 5472/1120 preparation | You |
| April 1 | Review draft filings from CPA | You |
| April 15 | File Form 5472 + Form 1120 (or Form 1065 if multi-member) | CPA |
| Anniversary month | File state Annual Report (Wyoming: first day of anniversary month) | You or registered agent |
| Quarterly (if ETBUS) | Estimated tax payments (Form 1040-ES) | CPA |
Common Mistakes Non-Residents Make
- Assuming "disregarded entity" means "ignore it." Disregarded for income tax does not mean disregarded for reporting. Form 5472 still applies.
- Mixing personal and business funds. Every transfer between you and the LLC must be documented for Form 5472. Use separate accounts and track everything.
- Missing the anniversary-month deadline in Wyoming. Delaware is March 1 for everyone. Wyoming is the first day of your formation month. We set a Google Calendar alert.
- Not claiming treaty benefits. If your country has a treaty and you pay 30% withholding, you are leaving money on the table.
- Filing Form 1040-NR when you do not need to. If you have no ETBUS and no FDAP, you do not file a personal US return. Only the LLC files Forms 5472/1120.
- Ignoring FBAR (FinCEN 114). If your foreign bank accounts hold over $10,000 total at any point, you must file FBAR separately from tax returns. This is personal, not LLC-related, but many non-resident founders forget it.
Quick Reference: Do You Owe US Tax?
Answer these three questions:
| Question | If Yes | If No |
|---|---|---|
| Do you have US-sourced FDAP income (rents, royalties, US service performed in US)? | 30% withholding (or treaty rate). File 1040-NR if overpaid. | No US tax on that income. |
| Do you have a US trade or business (ETBUS)? | Pay tax on net profit. File 1040-NR. | No US income tax. |
| Do you own 25%+ of a US LLC? | File Form 5472 + Form 1120 annually. | Standard LLC rules apply (different forms). |
Final Thoughts
US tax compliance for non-residents is not about paying massive tax bills. It is about filing the right forms on time. The IRS is less concerned with how much you owe and more concerned with whether you report.
We pay $62 to Wyoming, $400 to our CPA, and $0 to the IRS federal government. That is our entire US tax cost for a six-figure revenue LLC with no US-sourced income. The system is manageable if you respect the paperwork.
Do not let the $25,000 penalty scare you into paralysis. Let it motivate you to hire a good CPA, set calendar reminders, and treat your LLC like the legal entity it is.
