For Thai nationals investing in a US business on an E-2 visa
E-2 Investors From Thailand: Tax on the Business, the Investment and You
Investing in a US business from Thailand on an E-2? The visa is about immigration, but the tax questions start the day you fund the company: which entity, how the money goes in, and when the US starts taxing you on everything.
Quick answer
Is an E-2 investor from Thailand a US tax resident?
Usually yes, once living in the US for most of the year. E-2 is not an exempt-individual category under IRS Pub 519, so your days count under the substantial presence test, and a resident is taxed on worldwide income. If Thailand also treats you as resident, Article 4 (Residence) of the treaty breaks the tie. Your company files its own returns: Form 1120, and Form 5472 while it is foreign-owned.

What USCIS looks for
| E-2 condition (USCIS) | In short |
|---|---|
| Nationality | You must be a national of a treaty country; Thailand's E-2 treaty has been in force since June 8, 1968 (State Department) |
| Substantial investment | Capital at risk in a bona fide enterprise; no fixed minimum, judged against the cost of the business |
| Not marginal | The business must be able to earn more than a minimal living for the investor and family |
| Develop and direct | At least 50% ownership or operational control |
| Stay | Up to two years at a time, with extensions in increments of up to two years |

Structuring the E-2 business from Thailand
The structure you choose in the US decides the filings, not the visa. A corporation files Form 1120 every year (IRS). An LLC follows Treas. Reg. section 301.7701-3: disregarded with one owner, a partnership with more, or a corporation if it elects (IRS). Foreign ownership adds Form 5472 and its US$25,000 penalty (IRS), and a new business set up by someone from Thailand generally needs a BE-13 within 45 days (BEA rule).
Residence clarity for E-2 investors
| Question | Answer for an E-2 investor from Thailand |
|---|---|
| Are E-2 days excluded? | No. E-2 is not an exempt-individual category in IRS Pub 519 |
| When do I become a US tax resident? | When you meet the substantial presence test (31 days this year, 183 weighted days over 3 years), usually in your first full year |
| The first year | Usually dual-status: nonresident before the residency starting date, resident after |
| Resident in both countries? | Article 4 (Residence) of the treaty decides; Form 8833 discloses the position |
| Social security | No agreement on the SSA list |

Capital or loan
The money you bring from Thailand can go in as capital (shares or membership interest) or as a loan to the company. For tax reporting, the difference matters: while the company is foreign-owned, loans from you, the balance outstanding and any interest are related-party transactions on Form 5472 (IRS). Keep a loan agreement and bank records for every transfer.
Dividends and interest while you live in Thailand
Before you move, or in any year you are not a US resident, money the US corporation pays you is taxed by withholding. The statutory rate on US-source dividends and interest paid to a nonresident is 30% unless a treaty lowers it (IRS Pub 515).
| Payment to a resident of Thailand | General treaty rate (IRS Table 1) | Treaty citation |
|---|---|---|
| Dividends from a US corporation | 15% | Article 10(2) |
| Interest on a loan you made to the company | 15% | Article 11(2) |
Rates from IRS Tax Treaty Table 1 (Rev. May 2023). The IRS notes the table is not a complete guide to eligibility; the treaty's conditions, including any limitation on benefits, must be met. Once you are a US resident these rates no longer apply to you.
Ongoing US filings for an investor from Thailand
- Once you are a US resident you are no longer a foreign person for Form 5472, which the IRS defines as an individual who is not a citizen or resident (IRS). Whether the company still files depends on who else owns it.
- Form 1040 on worldwide income every year you are resident, including income from Thailand.
- FBAR and Form 8938 for accounts you keep in Thailand; see FBAR and FATCA and Form 8938.
- Form 5471 if you keep control of a company in Thailand: a US person controlling more than 50% of a foreign corporation is a Category 4 filer, with a US$10,000 penalty per year for not filing (IRS). See Form 5471.
- Funds held in Thailand can be PFICs; see PFIC and Form 8621 for how the rules work.

Common questions
What counts as a substantial E-2 investment from Thailand?
USCIS does not set a fixed minimum. The investment must be substantial in relation to the total cost of the business, and the lower the cost, the higher the proportion expected. The enterprise may not be marginal. Your immigration lawyer advises on this.
Does an E-2 investor from Thailand pay US tax on worldwide income?
Usually yes, once resident. E-2 is not an exempt-individual category, so the substantial presence test applies, and a US resident is taxed on worldwide income from the residency starting date.
What if Thailand also treats me as resident?
Article 4 (Residence) of the treaty decides residence for treaty purposes; claiming it on a US return needs Form 8833.
Does the E-2 company file Form 5472?
A US corporation that is 25% or more foreign-owned files Form 5472 with Form 1120, and a single-member LLC files it while its owner is a foreign person. Once you are a US resident you are no longer a foreign person for this purpose.
