Single-Member LLC With No US Income: Do You Owe US Tax?

A foreign-owned single-member LLC with no US income usually owes no US federal income tax. You still have to file every year, though. The IRS expects Form 5472 with a pro forma Form 1120, and your state charges its own annual fees whether or not you earned money.

Bottom line

• No US trade or business and no US-source income usually means $0 in federal income tax for a non-resident owner.
• Filing obligations don’t go away. Form 5472 is required for most foreign-owned single-member LLCs, and the penalty for missing it starts at $25,000.
• “US clients” is not the same as “US income.” Where you do the work matters more than where your customers live.

How does the IRS tax a single-member LLC owned by a non-resident?

By default, the IRS ignores the LLC for income tax and taxes the owner directly. A single-member LLC is a “disregarded entity,” which means its income shows up on the owner’s return instead of the company’s.

For a US citizen, that means everything flows onto their personal Form 1040. A non-resident alien is different. The US generally taxes non-residents on just two kinds of income:

1. Effectively connected income (ECI). Effectively connected income is income tied to a trade or business carried on inside the United States. It is taxed at regular graduated rates, and you report it on Form 1040-NR.
2. Fixed, determinable, annual, or periodical (FDAP) income. FDAP income is passive US-source income such as US dividends, some royalties, and rents. It is usually taxed at a flat 30% withholding rate, which a tax treaty can reduce.

If your LLC’s income falls into neither bucket, the US has nothing to tax at the federal level. That is the situation people mean when they talk about a “single-member LLC with no US income.”

What counts as “no US income”?

Income is generally foreign-source if you perform the work outside the US. The client’s location doesn’t matter. Under IRS sourcing rules, services income is sourced to the place where the services are performed.

That rule surprises many owners. A web developer in Portugal who bills American clients through a Wyoming LLC is usually earning foreign-source income, because the coding happens in Portugal.

Here is how common setups typically shake out:

“Usually” carries a lot of weight in that table. “US trade or business” is a facts-and-circumstances test, not a bright line. If anything in your setup looks like a physical or human presence in the US, have a professional review it.

Is a tax treaty relevant if I already owe nothing?

Yes. Treaties matter at the edges. Many US income tax treaties only allow the US to tax a resident of the other country’s business profits if those profits come from a “permanent establishment” in the US. That standard is often stricter than the domestic “trade or business” test.

So a treaty can protect you in borderline cases, such as an occasional trip to the US. To claim treaty benefits on a return, you generally need Form 8833, and you need to qualify as a resident of the treaty country.

Treaties also cover the other side of the question. Your home country almost certainly taxes you on what the LLC earns. In most countries, US tax-free does not mean tax-free.

What you still have to file with no US income

A foreign-owned single-member LLC has to file Form 5472 even when it owes zero tax. This is the requirement owners miss most often, and it is also the most expensive one to miss.

Form 5472 and the pro forma 1120

Treasury regulations treat a foreign-owned disregarded entity as a corporation for one narrow purpose: reporting transactions with its foreign owner. Each year, the LLC files:

• A pro forma Form 1120. You fill in only the name, address, and EIN, and write “Foreign-owned U.S. DE” across the top.
• Form 5472. This form reports “reportable transactions” between the LLC and its owner or related parties.

Reportable transactions are broader than most people expect. Money you put into the LLC, money you take out, formation costs you paid personally, and loans between you and the company all count. In practice, nearly every active foreign-owned LLC has something to report.

The penalty for failing to file or filing incomplete information is $25,000 per form, per year, under Internal Revenue Code section 6038A. The return is due on the regular corporate deadline, generally April 15 for a calendar-year LLC. Form 7004 extends it six months.

These forms generally can’t be e-filed the normal way. The Form 5472 instructions list a fax number and a mailing address, so check the current instructions before you send anything. Our Form 5472 guide walks through each line.

An EIN

To file Form 5472, the LLC needs an Employer Identification Number. A non-resident can get one without an SSN by filing Form SS-4 by fax or mail, or through a formation service that handles it.

Form 1040-NR (only if you have US income)

If you do have ECI or FDAP income that wasn’t fully covered by withholding, you file Form 1040-NR personally. With no US income, most owners don’t need it. A professional can confirm that for your facts.

Withholding forms for platforms

Payment processors and marketplaces often ask for a tax form to document that you are foreign. Because the LLC is disregarded, the form usually comes from you as the owner, typically Form W-8BEN for an individual. Filling it out correctly keeps payers from withholding 30% they shouldn’t.

State taxes and fees still apply

State obligations are separate from federal income tax and usually apply even if you earned nothing. Budget for them every year.

• Delaware charges LLCs a flat $300 annual tax, due June 1, according to the Delaware Division of Corporations.
• Wyoming requires an annual report with a license tax starting at $60, according to the Wyoming Secretary of State. The amount is based on assets located in Wyoming.
• New Mexico does not require an annual report for LLCs, which is one reason it gets cited as a low-cost option.
• California imposes an $800 annual franchise tax on LLCs that are registered there or doing business there, according to the California Franchise Tax Board. Forming in another state doesn’t automatically get you out of it.

You will also pay a registered agent every year, often in the range of $50 to $300 depending on the provider.

Sales tax is a separate question too. If you sell physical goods to US customers, some states may expect you to collect sales tax once you pass their thresholds. That obligation has nothing to do with income tax.

When “no US income” stops being true

Your tax position can change without a change in revenue. These are the most common triggers.

You spend working time in the US. Days you work from a US hotel produce US-source services income. Long stays can also raise questions about your tax residency.

You hire in the US. A US employee or a contractor who regularly signs contracts for you can create a US trade or business.

You hold inventory in the US. Using US warehouses, including marketplace fulfillment programs, is a fact pattern professionals disagree on. Get a written opinion before assuming zero tax.

You elect corporate tax treatment. If you file Form 8832 to treat the LLC as a C corporation, it becomes a US taxpayer in its own right. It pays the 21% federal corporate rate on its worldwide profits, and dividends to you can face withholding.

You add a member. A two-member LLC is taxed as a partnership by default. It files Form 1065, and withholding rules for foreign partners may apply.

Who can handle this alone

If your setup is simple, you can likely handle the filings yourself:

• You live abroad and do all the work from outside the US
• The LLC has one owner and no US employees, office, or inventory
• Your only transactions with the LLC are contributions and withdrawals
• You’re comfortable preparing Form 5472 and a pro forma 1120 every year and sending them on time

Even then, many owners pay a professional for the first year to set up a clean template, then repeat it themselves.

Who should hire a professional

Get professional help if any of these apply:

• You spend part of the year working in the US
• You sell physical products stored in US warehouses
• You’ve missed a Form 5472 in a prior year and need to fix it
• You’re considering a corporate election or adding a partner
• Your home country has its own controlled-foreign-company or transparency rules for foreign entities

A missed form is expensive enough that the cost of an accountant usually pays for itself. 1-800Accountant offers bookkeeping and tax filing for small businesses. Before you sign up, confirm that they handle Form 5472 for foreign-owned LLCs.

FAQ

Do I need to file anything if my LLC had zero revenue?

Usually, yes. If you put money into the LLC or paid its formation or registered agent fees yourself, those count as reportable transactions on Form 5472. States also expect annual reports and fees whether or not you had revenue.

Do US clients make my income US-source?

No, not for services. Under IRS sourcing rules, services income is sourced to where you perform the work. Work you do from outside the US is generally foreign-source, even if the client and the bank account are in the US.

Does my LLC pay state income tax if I owe no federal tax?

Most states follow the federal treatment, so a disregarded LLC with no in-state activity typically owes no state income tax. Flat annual fees and franchise taxes are separate. These include Delaware’s $300 LLC tax and California’s $800 franchise tax, and they apply regardless of income.

What happens if I already missed Form 5472?

The IRS can assess a $25,000 penalty per missed form, so don’t wait for a notice. A tax professional can help you file late returns, and if you qualify, they can include a reasonable-cause statement. Fixing it before the IRS contacts you generally works out better.

Get your filings right the first time

For most non-resident owners, the real risk with a single-member LLC isn’t a tax bill. It’s a missed filing. Keep a record of every transfer between you and the LLC, calendar the April 15 deadline, and pay your state fees on time. If you’d rather hand the paperwork to someone else, talk to 1-800Accountant about your foreign-owned LLC’s annual filings and confirm that Form 5472 is included before you commit.
