Form a Wyoming LLC from Thailand: Complete 2026 Guide

Wyoming in one paragraph: $100 to file ($102 online), then $60 (based on in-state assets, minimum $60, filed on the anniversary month) each year. The state imposes no state income tax and no franchise tax. Wyoming does not publicly list LLC member or manager names in its formation filings. For a Thailand-based owner the state choice mainly decides cost, privacy and paperwork, not your home-country tax result. If a low, predictable annual cost and strong privacy is what you are optimizing for, Wyoming deserves a close look.

The cost side of a Wyoming LLC: $100 state fee ($102 online), a registered agent at typically $100-150 per year, a free IRS EIN, and a bank account that is usually free. Annual state requirement in Wyoming: $60 (based on in-state assets, minimum $60, filed on the anniversary month). If you use EasyBrise, Global Launch is $295 for year one (registered agent included) and $149 per year after, and for a founder in Thailand the whole first year typically comes in well under $500.

Thai freelancers, developers, agency owners and online sellers form US LLCs to invoice international clients in dollars and to hold a US business bank account. Thai tax residents, which includes anyone who spends 180 days or more in Thailand in a tax year, are taxed on foreign income when it is brought into Thailand. That remittance rule changed from January 1, 2024, and it is the single most important Thai-side point for a US LLC owner.

Wyoming fits if you want the lowest ongoing annual cost combined with strong privacy and no state income tax, and you don't need a Delaware-specific court system or investor familiarity. Check the comparison table above before you commit, as switching later is not a simple amendment: the Wyoming LLC would be dissolved and a new one formed elsewhere.

Your Wyoming LLC exists once the state accepts the filing, but it is only ready to trade after these steps: sign the Operating Agreement; get the bank account open; apply for payment processors; calendar your Wyoming annual obligation ($60 minimum, filed in your LLC's anniversary month) and the federal Form 5472 and pro forma 1120. On BOI: FinCEN's rule in force since August 14, 2026 permanently exempts all US-formed LLCs, so there is nothing to file there.

Wyoming's low and predictable costs, $100 to file and a $60 minimum annual fee, suit a Thai founder whose main planning effort is on the Thai side: when and how money is brought into Thailand.

Here is how Wyoming formation works for someone in Thailand. File the Articles of Organization with the Wyoming Secretary of State, using a registered agent's physical Wyoming address. Request your EIN from the IRS, writing "Foreign" or "N/A" in place of an SSN (phone: 267-941-1099, about 45-60 minutes; fax or mail: 4-6 weeks). Then apply for Mercury or Relay online. Every step can be done remotely.

The United States and Thailand signed an income tax convention in 1996, in force since the late 1990s. Thailand's own rules do not clearly set out how a foreign tax credit for individuals works in the remittance context, and the Revenue Department has said it intends to issue guidance and amend the tax return form to facilitate credit claims. Until that guidance settles, keep the LLC's US filings and proof of any US tax paid for your Thai accountant.

Under Revenue Department instruction Por. 161/2566, issued in September 2023, foreign-sourced income of a Thai tax resident is subject to Thai personal income tax when it is brought into Thailand, regardless of the year in which it was earned. Before the change, income remitted in a later calendar year was exempt under a 1987 interpretation, and that exemption no longer applies for amounts brought in from January 1, 2024. In practice this means the timing and character of withdrawals from the LLC matter, and a Thai tax adviser should map them before you start. On the US side the LLC files Form 5472 and a pro forma Form 1120 every year, with a $25,000 minimum penalty for a missed or incomplete filing.

As a Thai owner, your recurring dates look like this. State: Wyoming's annual report and $60 minimum fee fall due in your LLC's anniversary month. Federal: Form 5472 with the pro forma Form 1120 is due on the return due date, April 15 for a calendar-year LLC, extendable with Form 7004. For the one-off EIN call, the IRS line (6 a.m. to 11 p.m. Eastern) is open 5 p.m. to 10 a.m. Thai time in US daylight time (6 p.m. to 11 a.m. in US standard time). Put the state date and the federal date in your calendar when the EIN arrives, because a missed Form 5472 carries a $25,000 minimum penalty.

Over five years, the state-level cost of a Wyoming LLC is a $100 filing fee plus $60 a year for five years, so $400 in total, before the registered agent. That makes Wyoming the middle of the five states on this measure. The same arithmetic across the five states runs from $50 to $2,110. For a Thai owner, the bigger variable is not this US state cost but Thailand's remittance rule, under which foreign income is taxed when it is brought into Thailand.

Thailand is not on Mercury's prohibited-countries list, which is based on country of residence, and it is not on Relay's list, which looks at owners' citizenship and residency. Both banks run their own reviews, so approval is never guaranteed. Neither bank's published rules restrict international wires involving Thailand. Because Thai tax can depend on when funds are brought into Thailand, keep a clear record of each transfer from the US account, including its date, amount and what it represents.

Under the 2024 change, the question is not when the LLC earned income but when you bring it into Thailand. Keep the LLC's money in the US account until you need it, record each transfer, and ask your adviser how salary-type payments, distributions and card spending in Thailand from a foreign account would each be treated. Some of those points, such as whether spending through a foreign account counts as a remittance, were open questions when the rule was introduced.
