ITIN for Foreign-Owned U.S. LLC: What Non-Residents Actually Need (2025–2026)

Non-residents who own a U.S. LLC often need both an EIN for the business and an ITIN for personal filings. Missing the ITIN can trigger a $25,000 IRS penalty. Here's what you need and when.

The most common message we receive from new LLC owners goes something like this: "I already have an EIN for my LLC — do I still need an ITIN?"

The short answer is: almost certainly yes. The EIN identifies your business. The ITIN identifies you. They serve different purposes, and assuming the EIN covers everything is an expensive mistake that leads directly to IRS penalty notices.

The $25,000 Problem Most LLC Owners Don't Know About

Before getting into the details, here's the piece that tends to get people's attention:

If you are a foreign person who owns a single-member U.S. LLC, your LLC is required to file Form 5472 every year — even if the LLC had zero income, zero activity, and zero bank transactions.

Form 5472 is an information return. It reports the existence of a foreign owner to the IRS. The penalty for not filing is $25,000 per form per year, with no upper limit for ongoing non-compliance.

The LLC's EIN goes on the filing. But to properly complete the associated return and to file your personal 1040-NR (which is required if the LLC had any real activity), you need an ITIN.

This isn't theoretical. We regularly see clients who formed LLCs, operated for 2–3 years, and never filed 5472. When they come to us, the first thing we deal with is the backlog of IRS notices.

EIN vs. ITIN: The Actual Difference

EIN (Employer Identification Number) — your LLC's tax ID. Used for the LLC's bank accounts, business tax filings (Form 5472, 1120, 1065), and payment platforms. Non-residents can get an EIN without an SSN or ITIN by filing Form SS-4.

ITIN (Individual Taxpayer Identification Number) — your personal tax ID. Used when you — as an individual — have a U.S. tax filing obligation. Non-residents can't get an SSN, so an ITIN is the only option.

One LLC can require both: the EIN for the entity itself, and the ITIN for the person who owns it.

Four Situations Where the LLC Owner Needs an ITIN

1. Filing Form 1040-NR

If your U.S. LLC generates income from U.S. sources — sales, services, rent — that income is "effectively connected" with a U.S. trade or business. That triggers a personal filing obligation on Form 1040-NR.

Form 1040-NR requires a Taxpayer Identification Number. Non-residents without an SSN need an ITIN. No ITIN means you can't properly file the return.

2. Form 5472 and the Pro Forma 1120

Even without real income, a foreign-owned single-member LLC must file Form 5472 attached to a "dummy" (pro forma) Form 1120. The LLC owner's ITIN may be needed to complete the return and to establish your identity in IRS records.

3. Claiming Treaty Benefits

If your country has a tax treaty with the U.S. that reduces withholding on royalties, dividends, or interest, you claim that benefit by submitting Form W-8BEN to the platform paying you. W-8BEN asks for your U.S. TIN. Without an ITIN, you can't claim the reduced rate and the platform defaults to 30%.

4. Banking Requirements

Some U.S. banks — particularly when opening a business account for a foreign-owned LLC — ask for the personal ITIN of the beneficial owner, not just the EIN. Mercury, Relay, and some credit unions have asked for this.

The Typical Timeline for New LLC Owners

A realistic plan for someone forming a U.S. LLC from outside the U.S.:

StepTypical Timeline
Form LLC with state1–5 business days
Get EIN via Form SS-4 (fax)4–6 weeks
Prepare and submit W-7 for ITIN (through a CAA)1–2 weeks after EIN
IRS processes ITIN (outside tax season)7 weeks
IRS processes ITIN (tax season: Jan 15–Apr 30)9–11 weeks

The EIN and ITIN applications are independent. You don't need one to apply for the other. Most people apply for the EIN first (needed to open a bank account) and then apply for the ITIN as soon as their first tax year approaches.

How to Apply for an ITIN as a Foreign LLC Owner (Exception 5 / TD9363 Pathway)

Many single-member LLC owners ask: "I don't have a U.S. tax return yet — how do I apply for an ITIN?"

The answer is W-7 Exception 5, based on Treasury Decision 9363. This exception was created specifically for foreign-owned U.S. disregarded entities (single-member LLCs) who need an ITIN for Form 5472 compliance but haven't yet filed a 1040-NR.

On Form W-7: Check Reason h (Other) and write "Exception 5 — TD 9363" in the description field. Do not write "Exception h" — that's a reason code, not an exception, and the IRS will reject the application.

Documents required:

  • EIN confirmation letter (CP575 or 147C from IRS)
  • LLC formation documents (Articles of Organization or Certificate of Formation)
  • Operating agreement or other document showing you as the sole member
  • Brief explanation letter stating the ITIN is needed for Form 5472 compliance under TD 9363
  • Identity documentation (passport, verified by a CAA)

No tax return needed. The exception documentation substitutes for the return.

Once the ITIN is assigned (7–11 weeks), use it to file Form 5472 (attached to a pro forma Form 1120) for each year the LLC has been in existence with reportable transactions.

If you do have a tax return to file (because your LLC generated income), skip Exception 5 and use Reason b with your Form 1040-NR attached instead.

2026 Update: New CAA Requirement

Effective June 1, 2026, CAAs submitting Form W-7 applications under Exception 1(a) — partnership or LLC income — must include a copy of the relevant portion of the LLC or partnership agreement that shows:

  • The LLC's name and EIN
  • The applicant's name and signature

If your ITIN application is tied to LLC ownership and uses this exception category, make sure your CAA has this document before submission.

What Happens If You Don't Have an ITIN

The consequences stack up in predictable ways:

  • $25,000 penalty: Per Form 5472 not filed, per year
  • 30% withholding: Platforms withhold 30% when they can't verify your tax status. This applies to Amazon payouts, Stripe payments, YouTube revenue from U.S. viewers, and others.
  • Can't file 1040-NR: If you're required to file and don't have an ITIN, you can't do it properly. Late filing penalties start immediately after the deadline.
  • Account holds: Some payment processors freeze accounts pending tax verification when they don't have a valid TIN on file.

Frequently Asked Questions

My LLC made no money this year. Do I still need an ITIN?

Possibly. Form 5472 must still be filed if your LLC had any "reportable transactions" — which includes contributions to the LLC, distributions, and certain intercompany transactions, not just revenue. If your LLC was truly dormant with zero transactions, consult a tax professional to confirm whether 5472 applies. But if there was any activity, file it.

Can I get an ITIN before my LLC is active?

Technically you can apply for an ITIN once you have a tax reason — which could be your first 1040-NR filing. For most new LLC owners, the first ITIN application is submitted when the first tax return is prepared, which is 3–6 months after forming the LLC.

Does an EIN expire? Does an ITIN expire?

EINs don't expire. ITINs expire if not used on a U.S. federal tax return for three consecutive years. ITINs not used on any return in 2022, 2023, or 2024 expired on December 31, 2025. If you have an old ITIN and haven't filed recently, check before you need it.

I formed an LLC five years ago and never applied for an ITIN. What should I do?

First: don't panic, but act quickly. You may have missed Form 5472 filings, which can accumulate significant penalties. The IRS has a first-time penalty abatement program, and voluntary disclosure sometimes reduces the penalty. Work with a U.S. tax professional who handles foreign-owned LLC compliance. While you're doing that, apply for the ITIN so future filings are in order.

Do I need to visit the U.S. to get an ITIN?

No. Through a Certified Acceptance Agent, the entire process is remote. You verify your passport on a video call, we prepare Form W-7, and we handle the IRS mailing. You never mail your passport or set foot in the U.S.
