Why Register a Company in Thailand?

Thailand has grown steadily since the 1960s into a newly industrialized, upper-middle-income economy and the second largest in Southeast Asia, with exports accounting for roughly two-thirds of GDP. The country is ASEAN’s largest exporter of computers and electronic components, its leader in automotive production, a major gem and food exporter, the world’s second-largest rice exporter, and a consistent top-ten global destination for tourism and medical tourism. Its strategic position gives foreign investors a gateway to the fast-growing markets of China, India, Indochina, and the rest of ASEAN, supported by strong rail, road, port, and airport connectivity. For companies looking to build a regional base or a manufacturing and export operation, that combination of scale, infrastructure, and market access is hard to match elsewhere in the region.

Much of Thailand’s forward momentum is concentrated in the Eastern Economic Corridor, a national initiative spanning Chonburi, Rayong, and Chachoengsao provinces that has attracted a growing share of the country’s foreign direct investment in recent years. The government is channeling incentives toward ten target industries, from automotive and electronics to robotics, digital services, and biotechnology, while the Board of Investment offers corporate tax holidays of up to thirteen years, import duty relief, land ownership rights for promoted projects, and streamlined work permit quotas for foreign specialists. Combined with a standard 20% corporate tax rate that is competitive within Asia, these incentives are a genuine draw for manufacturers, exporters, and technology companies weighing where to locate a Southeast Asian operation.

That said, Thailand is not a fully open market for foreign capital. The Foreign Business Act of 1999 restricts foreign ownership to 49% across a wide range of service, retail, and professional sectors unless a company secures BOI promotion, a Foreign Business License, or qualifies under a treaty exemption such as the US-Thai Treaty of Amity. Tightened 2026 rules now require Thai shareholders to document genuine beneficial ownership and apply an actual-control test that can reclassify a nominally Thai-majority company as foreign if a foreign partner controls the board or financing. Investors should treat ownership structuring as a first-order legal question, not an afterthought.

Step-by-Step Process to Set Up a Company in Thailand

1

Reserve the Company Name

Submit up to three preferred names to the Department of Business Development through its digital DBD Biz Regist platform; an approved reservation is valid for 30 days.

2

File the Memorandum of Association

Register the company’s objectives, registered capital, and shareholder structure with the DBD as the first formal incorporation filing.

3

Register the Company and Appoint Directors

Complete incorporation within three months of the memorandum filing, submitting shareholder lists, director details, and proof of paid-up capital; the digital system now processes most filings within one to five business days.

4

Apply for a Foreign Business License or BOI promotion (if required)

Businesses with more than 49% foreign ownership outside exempted activities must secure a Foreign Business License, which carries a statutory 60-day review and a further 15 days to issue, or apply for BOI promotion for eligible priority-sector projects.

5

Register for Tax with the Revenue Department

Obtain a corporate tax identification number and, once annual turnover exceeds THB 1.8 million, register for VAT within 30 days of crossing the threshold.

6

Register Employees with the Social Security Office

Enroll any Thai staff with the SSO before their first payday to activate mandatory social security contributions.

7

Open a Corporate Bank Account and Finalize Capital Remittance

Deposit registered capital according to the company’s structure, since branch offices and representative offices face phased capital remittance schedules over their first two years.

Hiring and Managing Employees

Companies that want to hire in Thailand without first completing full incorporation often turn to an Employer of Record, which legally employs staff on the company’s behalf while handling contracts, payroll, tax withholding, and statutory benefits. This route can get a first hire onboarded in days rather than the weeks or months a full entity setup requires, making it a practical way to test the market or hire quickly while a Thai Limited Company or BOI application is still in progress.

Thailand’s minimum wage is set provincially and ranges from roughly THB 337 to THB 400 per day in 2026, with Bangkok, Phuket, and the industrial provinces of Chonburi and Rayong sitting at the top of the scale. The Labour Protection Act guarantees a minimum of six days of paid annual leave after a year of service, thirteen public holidays, up to 30 days of paid sick leave, and severance pay that scales from 30 days’ wages after 120 days of employment to 400 days’ wages after 20 years. Employers and employees each contribute 5% of monthly wages to the Social Security Fund, which now applies to a wage base capped at THB 17,500 per month and funds healthcare, maternity, unemployment, and pension benefits.

Foreign nationals cannot legally work in Thailand without a Non-Immigrant B visa followed by a work permit issued by the Ministry of Labour, a process that typically takes one to a few weeks once a Thai employer sponsors the application; BOI-promoted companies and Smart Visa holders benefit from faster, more relaxed processing. Given Thailand’s tight market for English- and Chinese-speaking professionals, many foreign employers also lean on a local recruitment agency to source and vet candidates rather than trying to navigate job boards and hiring norms without on-the-ground expertise.

Tips for Recruiting and Retaining Local Talent

  • Confirm early whether your intended business activity falls under the Foreign Business Act’s restricted lists, since this determines whether you need a Thai majority shareholder, a Foreign Business License, or BOI promotion.
  • Budget for the Foreign Business License’s statutory 60-day review period if your structure requires one, and start the application well before you need to be operational.
  • Keep documentation of genuine Thai beneficial ownership on file, since 2026 DBD rules apply an actual-control test that can reclassify a nominally Thai-majority company as foreign.
  • Register for VAT within 30 days of crossing the THB 1.8 million turnover threshold, and file monthly returns with the Revenue Department to avoid penalties.
  • Enroll every Thai employee with the Social Security Office before their first payday and reconcile employer and employee contributions each month.
  • Work with a local law firm, accountant, or incorporation partner who can navigate DBD filings, Foreign Business License applications, and BOI submissions in parallel rather than sequentially.

Why Now is the Right Time to Register a Company in Thailand

Thailand presents a more layered proposition than many of its Southeast Asian neighbors: a large, well-established consumer market and manufacturing base, but one where the Foreign Business Act keeps a meaningful list of activities restricted to majority Thai ownership unless a company qualifies for an exemption. For companies weighing Thailand as a manufacturing hub, a regional headquarters location, or an entry point into one of ASEAN’s largest domestic markets, the practical question isn’t really which structure to choose, it’s whether the intended business activity can achieve full foreign ownership at all, and that answer shapes everything else about setup time and cost.

That’s what makes the BOI-Promoted Company route so central to Thailand’s investment landscape. For companies in eligible manufacturing, technology, or export-oriented sectors, BOI promotion is often the difference between operating under standard 51% Thai ownership rules and securing up to 100% foreign ownership, along with tax incentives that can materially change a project’s economics. The tradeoff is time: a BOI application adds two to four months on top of standard registration, so it suits companies planning a substantial, long-term operation rather than a quick market test. Where BOI promotion isn’t available or isn’t worth pursuing, a standard Thai Limited Company with Thai co-shareholders, a Branch Office, or a Representative Office each serve narrower, more specific purposes depending on whether the goal is local revenue generation or non-trading liaison work.

Given how much hinges on activity classification under the Foreign Business Act, it’s worth confirming BOI eligibility and foreign ownership limits for the specific business activity before committing to a structure or timeline.

Frequently Asked Questions

The Foreign Business Act restricts foreign majority ownership in certain business activities deemed sensitive to Thai economic interests, unless a company qualifies for an exemption or obtains a Foreign Business License. This is the central regulatory hurdle for most foreign investors in Thailand, and it's worth checking which list a given business activity falls under before assuming full foreign ownership is available.

BOI (Board of Investment) promotion is a separate application process from standard company registration, targeted at manufacturing, technology, and export-oriented projects in sectors Thailand wants to attract. Approved BOI companies can access up to 100% foreign ownership and various tax incentives that wouldn't otherwise be available under standard Foreign Business Act rules, though the application itself adds meaningful time to the overall setup process.

Yes, a standard Thai Limited Company requires a minimum of three shareholders, and unless the business qualifies for a foreign ownership exemption (such as through BOI promotion or a US-Thai Treaty of Amity for eligible American companies), Thai nationals must hold at least 51% of the shares. This requirement is one of the most significant structural differences between Thailand and many neighboring jurisdictions.

The US-Thailand Treaty of Amity allows qualifying American-owned businesses to operate in Thailand with majority or full US ownership in most sectors, bypassing standard Foreign Business Act restrictions that apply to other foreign investors. Eligibility requires the company to be majority US-owned and meet specific certification requirements, so it's worth confirming qualification with a Thai legal advisor before assuming this route applies.

Registered companies must obtain a tax identification number, register for VAT if revenue exceeds the statutory threshold, and file corporate income tax returns annually, with standard corporate tax rates applying to most business activities. BOI-promoted companies may qualify for corporate tax holidays or reductions depending on the approved activity, so it's worth confirming current rates and any applicable incentives with a Thai tax advisor before finalizing financial projections.
