Foreign-Owned LLC Taxes: What Non-Resident Owners Must File & Pay (2026)

Ask ten people how a US LLC owned by a non-resident is taxed, and you'll hear two opposite answers.

"You pay no US tax at all."

"You pay US corporate tax on everything."

Both are wrong, and believing either one can be expensive. The truth about foreign-owned LLC taxes depends on two things: how your LLC is classified, and where your income is actually earned. And whatever you owe in tax, there's one filing almost every foreign-owned LLC must make, with a $25,000 penalty if it's missed.

Here's how it all works in plain English.

How the IRS Classifies a Foreign-Owned LLC

An LLC doesn't have its own tax category. The IRS taxes it in one of three ways:

• Single-member LLC: treated as a disregarded entity by default, meaning the IRS looks through the LLC to its owner
• Multi-member LLC: treated as a partnership by default
• Either type: can elect to be taxed as a C-Corporation

Most Indian and international founders own a single-member LLC, so let's start there.

Foreign Owned Single-Member LLC Tax: The Rules

Income Tax: It Depends on Where the Work Happens

The US generally taxes a non-resident only on income that's effectively connected with a US trade or business, often called ECI.

In practice, the key question is: where is the work done?

• If you live in India and perform services from India for clients worldwide, that income is generally not treated as US-connected, even if the clients are American and the money lands in a US bank account.
• If your LLC has a US office, US employees, or people working for it inside the US, some of its income can become US-connected and taxable.

If your LLC does have ECI, you'll typically need to file a personal US return, Form 1040-NR, which usually requires an ITIN. Our guide to the ITIN for non-resident LLC owners explains when you need one.

Common mistake: Assuming "my LLC is American, so my income is American." For tax purposes, what matters is where the income is earned, not where the company is registered or where the bank account is.

Reporting: Form 5472 Is (Almost) Always Required

Here's the twist. Even when your single-member LLC owes zero US income tax, the IRS treats it like a corporation for reporting purposes.

That means filing Form 5472 with a pro forma Form 1120 every year. It reports the money that moved between your LLC and "related parties", which is mostly you.

It applies even if your LLC:

• Had no income
• Had no customers
• Only received your initial capital contribution

Our Form 5472 and 1120 filing guide walks through how to complete it.

Foreign-Owned LLC Reporting and Taxes: Key Deadlines

• Due date: April 15 for calendar-year LLCs, so the 2026 tax year is due April 15, 2027
• Extension: File Form 7004 before April 15 to extend the deadline to October 15
• How to file: The pro forma Form 1120 with Form 5472 is mailed or faxed to a dedicated IRS unit, not filed the usual way

Pro tip: Filing Form 7004 even one day before April 15 also extends your Form 5472. If you're running late, file the extension first.

LLC Taxes for Non-Residents with Partners

A multi-member LLC with foreign owners files a partnership return, Form 1065, and gives each member a Schedule K-1 showing their share of profits.

If the partnership has ECI, it generally must withhold US tax on the foreign partners' share and pay it to the IRS. Each foreign partner then files their own 1040-NR to report it.

Multi-member LLCs involve more filings and more risk, so they're worth setting up with a tax professional from day one.

LLCs Taxed as a C-Corporation

Some founders elect C-Corp taxation, often because they plan to raise investment. Then the LLC:

• Files Form 1120 and pays the 21% federal corporate tax on its profits
• Still files Form 5472 if it's 25% or more foreign-owned
• Withholds tax on dividends paid to foreign owners, at 30% by default, though tax treaties (like the US–India treaty) can reduce that rate

This route can mean paying tax twice, once at the company level and again on dividends, so it suits some businesses far better than others.

Don't Forget State Taxes

Federal rules are only part of the picture. Depending on your state, your LLC may also owe:

• Annual report fees or franchise taxes, such as Wyoming's yearly license tax (see our Wyoming LLC cost breakdown)
• State income tax, if the LLC earns income connected with that state
• Sales tax, if it sells taxable products to customers in that state

Some states are far more expensive than others. California, for example, charges every registered LLC at least $800 a year, as explained in our California foreign LLC registration guide.

What Happens If You Don't File?

The IRS takes Form 5472 very seriously:

• $25,000 penalty for each missing, late or substantially incomplete form, per year
• Additional penalties can build up if you don't respond after the IRS sends a notice
• Each missed year counts separately, so three unfiled years can mean three penalties

The good news is that problems caught early can often be fixed. Filing missed years and requesting penalty relief is far easier before the IRS contacts you.

Your Home Country Taxes Still Apply

US tax rules are only half the story. If you live in India, you're generally taxed on your worldwide income, including your LLC's profits, whether or not the US taxes them. Our US LLC tax guide for Indian founders explains the India side, and our guide to ODI compliance for a US LLC from India covers the FEMA reporting rules.
