Form 5472 for Thailand Residents with a US LLC

A Thailand-based owner of a US single-member LLC must file Form 5472 with a pro forma Form 1120 each year the LLC had a reportable transaction with them. Unlike the UAE, Thailand has an income tax treaty in effect with the United States and does issue individuals a personal tax number — but neither changes the filing.

Agency owners in Bangkok and Chiang Mai, ecommerce sellers in Phuket and consultants on long stays often form a Wyoming, Delaware or New Mexico LLC because Stripe, US banking and US clients are easier to reach through a US entity. The LLC was a payments decision. Form 5472 comes with it anyway.

Two features of the Thai position change the mechanics of the filing compared with a UK or Indian owner. Neither removes the obligation. A treaty is in effect, which leads people to assume something has been switched off — nothing has. And Thailand issues personal tax numbers mainly to people who have become taxpayers there, so many short-stay owners have nothing to enter in the FTIN box.

If you want the filing done rather than explained, we prepare and fax the complete package from $149.

Do Thailand residents have to file Form 5472?

Yes, on the same terms as any other non-US owner, when three conditions are met:

1. The LLC is a US disregarded entity — a single-member LLC that has not elected to be taxed as a corporation.
2. Its sole member is a non-US person. A Thai national or foreigner in Thailand who is not a US citizen, green card holder or US tax resident qualifies.
3. There was at least one reportable transaction during the tax year between the LLC and its owner or another foreign related party.

Treasury Regulation § 1.6038A-1 treats a foreign-owned US disregarded entity as a corporation separate from its owner, solely for the § 6038A reporting rules, for tax years beginning on or after 1 January 2017 and ending on or after 13 December 2017. Whether you pay Thai tax is irrelevant.

Reportable transactions move between you and your own LLC, not between the LLC and its customers.

More examples are in our guide to customer payments and Form 5472.

The IRS Instructions for Form 5472 state that a $25,000 penalty may apply for failure to file when due and in the prescribed manner, for a substantially incomplete form, or for failure to keep the required records. A substantially incomplete Form 5472 counts as a failure to file. The penalty is not automatic for every mistake.

Does the US-Thailand tax treaty change anything?

An income tax treaty between the United States and Thailand is in effect, and it changes nothing about Form 5472.

The IRS's Table 3, List of Tax Treaties, which lists countries with tax treaties in effect with the United States, gives Thailand a general effective date of 1 January 1998. The text is on the IRS treaty A-to-Z page.

A treaty allocates taxing rights over income, which can matter if your LLC has US-source income.

No treaty excuses an information return. Form 5472 is filed under IRC § 6038A, a reporting provision, and no article of the US-Thailand treaty exempts anyone from it. A Thai-resident owner files on the same terms as an owner from a country with no treaty at all.

What goes in the FTIN box if you live in Thailand?

Enter your Thai tax number if you have one. If you do not, write "None" in the FTIN block and enter a self-assigned reference ID number on line 4b(2).

The Revenue Department's tax identification page states that a taxpayer shall obtain and use a taxpayer identification number (TIN), but an individual need not apply if he has and uses a personal identification number (PIN) under the civil registration law. A person without a PIN — the page names a foreigner first — applies on Form L.P. 10.1 within 60 days from the date he derives assessable income.

In practice, a Thai citizen uses the PIN, a foreigner who has become a Thai taxpayer applies for a TIN, and a foreigner with no Thai assessable income usually has no Thai tax number at all:

The last column never changes. Your Thai status changes one box, not whether the form is due.

Do not put a passport, driving licence or work permit number in the FTIN field, or a Thai company's tax number — none is your personal tax identification number. Do not apply for a US ITIN just to fill the box. Our FTIN and reference ID guide covers the format.

For the Part II address, use your actual address in Thailand, not your registered agent's US address.

Does Thai tax affect the US filing?

No. Thai personal income tax and the US information return are separate systems. What follows is context only.

The Revenue Department's personal income tax page states that a "resident" means any person residing in Thailand for a period or periods aggregating more than 180 days in any tax (calendar) year. A resident is taxed on income from Thai sources and on the portion of foreign-source income brought into Thailand; a non-resident is taxed only on Thai-source income.

Watch the boundary wording. That page says more than 180 days; the Revenue Department's Q&A on section 41, paragraph 2, of the Revenue Code says 180 days or more in the calendar year, with examples in which 184 days makes a person resident and 179 days does not. If you are within a day or two of the line, confirm it with the Revenue Department or a Thai adviser.

On foreign income brought into Thailand, the Revenue Department's Q&A on section 41, paragraph 2, issued by its Legal Affairs Division to explain Departmental Instructions Paw. 161 and Paw. 162, sets two conditions. First, foreign-source income arises on or after 1 January 2024 in a tax year in which the person was in Thailand 180 days or more. Second, that income is brought into Thailand in that year or any later year. It is then taxed in the year it is brought in. Income arising before 1 January 2024 is not taxed when brought in later, and returning your own invested capital is not assessable income.

That Q&A is the latest Revenue Department statement of the position we could locate, read on 18 September 2026. Later changes have been reported, but we could not confirm any from a Revenue Department publication, so treat any newer position as unverified until you check the Revenue Department's own page or ask a Thai tax adviser. We do not advise on Thai tax.

A visa does not decide tax residence. A Ministry of Foreign Affairs DTV information sheet describes the Destination Thailand Visa as designed for foreigners on a tourist trip who work remotely, with a "workcation" purpose covering digital nomads, remote workers, foreign talent and freelancers. The visa is valid for five years, and each stay is a maximum of 180 days, extendable once in the country through immigration. Financial and document requirements depend on the embassy where you apply. One full DTV stay sits right on the Revenue Department's day threshold, and an extension takes you past it. Neither the visa nor the day count affects Form 5472.

How does a Thailand-based owner actually file?

You cannot e-file. A foreign-owned US disregarded entity files Form 5472 on paper, by fax or by mail.

1. Prepare the pro forma Form 1120. Write "Foreign-owned U.S. DE" across the top of page 1. Only the LLC's name and address and items B and E are required.
2. Prepare Form 5472. Part I for the LLC; Part II for you, with your Thai address and either your Thai tax number or "None" plus a reference ID; Part IV for monetary transactions; a Part V statement itemizing contributions and distributions.
3. Convert baht to US dollars at a reasonable rate for each transaction date, applied consistently, and record the rate's source.
4. Sign and send. Fax to 855-887-7737, or mail to Internal Revenue Service, 1973 Rulon White Blvd, M/S 6112, Attn: PIN Unit, Ogden, UT 84201.
5. Keep the timestamped fax receipt. The IRS sends no acknowledgement. The receipt is evidence of transmission, not IRS acceptance of the return.

The regular due date for a calendar-year LLC is generally 15 April; Form 7004, filed by that date, extends it.

Getting it filed from Thailand

The Thai details — a treaty that changes nothing, a tax number you may not have, baht conversion, sometimes a Thai company as a second related party — are routine once you have seen them, and are exactly what makes a do-it-yourself form substantially incomplete.

We prepare Form 5472, the pro forma Form 1120 and the Part V statement; a qualified tax accountant reviews each package; we fax it to the IRS Ogden PIN Unit and send you the timestamped receipt. Late years include a reasonable cause letter.

$149 Standard, ready in 5–7 business days. $199 Express, within 3 business days. +$99 per additional past tax year. IRS fax delivery included.

We are not a CPA firm and do not give tax advice, including on Thai tax. We prepare and submit the US information return.

Start your filing — about 15 minutes.

Frequently asked questions

Do I have to file Form 5472 if I live in Thailand and my LLC made no profit?

Yes, if there was a reportable transaction. Profit is irrelevant. Funding the LLC, lending to it or taking money out of it is enough to require the form for that year.

Is there a tax treaty between the US and Thailand?

Yes. The IRS lists Thailand among the countries with a tax treaty in effect with the United States, with a general effective date of 1 January 1998. The treaty can affect how income is taxed. It does not affect Form 5472.

What FTIN do I use if I have no Thai tax number?

Write "None" in the FTIN block rather than leaving it blank, and enter a self-assigned reference ID number on line 4b(2). Use the identical reference ID every year you file.

Does holding a DTV make me a Thai tax resident?

Not by itself. The visa grants permission to stay; the Revenue Department decides residence by counting days in the calendar year. A long DTV stay can take you past the 180-day threshold, but the visa is not the test.

Do I owe Thai tax on money my US LLC pays me?

That depends on Thai law, your days in Thailand and when money is brought in, which is a question for the Revenue Department or a Thai adviser. Whatever the answer, your Form 5472 obligation is unchanged.

Does my Thai company need to be reported too?

Yes, if it transacted with your US LLC and you own or control it. It is a foreign related party, and each related party gets its own Form 5472.

I have never filed and my LLC is three years old. What now?

File every outstanding year soon, with a reasonable cause statement, ideally before the IRS contacts you. Each year carries its own exposure. Our late filing guide sets out the order.
