The Ultimate 2026 Guide to Setting Up a Company in Thailand

8 Most Common Questions from Foreigners. Fully Answered

Company Registration. Shareholding. BOI.Taxation and Work Permits (2026 Latest Edition)

In recent years, Thailand has become one of the most popular investment markets in Southeast Asia. Beyond manufacturing, sectors including AI and data centers, new energy, e-commerce, real estate, cross-border trade, restaurant brands, medical aesthetics, software SaaS, logistics, and pet-related businesses have all seen large numbers of foreign companies entering Thailand.

But a quick search on Google, Reddit, or Facebook groups reveals that the most discussed topic isn’t “whether it’s worth investing,” but rather — how do you legally set up a company?

This article compiles the 8 most searched, most discussed, and most easily overlooked questions among foreign investors, with a complete analysis.

Q 01　Can foreigners own 100% of a Thai company?

» Yes, but you need to go through the right channel.

In most industries, Thai law caps foreign shareholding at 49% (holding 50% or more is considered a foreign company). However, this doesn’t mean you can only be a minority shareholder — through IEAT, BOI investment promotion, a Foreign Business License (FBL), or specific industries opened up in 2026, foreigners can fully own 100% of a company. The key is first confirming which category your business activity falls under, then choosing the appropriate company structure.

Q 02　How much capital do I need to prepare to set up a company?

» It depends on whether you plan to apply for a work permit.

The most common scenario is: the company has foreign directors or employees, and plans to apply for a Work Permit.

In this case, the generally recommended registered capital is 2 million baht per foreign work permit applicant.

For example:

  • 1 foreign employee: recommended registered capital of 2 million baht
  • 2 foreign employees: recommended registered capital of 4 million baht

In addition, non-BOI companies generally also need to meet the Thai employee ratio requirement (4 Thai employees per foreign work permit) and other regulations in order to successfully apply for a work permit.

Practical reminder:

This capital is operating funds that the company can use — it is not a fee paid to the government. However, it must actually be deposited and supported by proof of remittance, as the Labour Department and Immigration Bureau will use it as the basis for issuing work permits and visa extensions.

Q 03　Can I have a Thai person hold 51% as a nominee?

» It’s advisable not to.

Over the past two years, the Thai government has begun large-scale investigations into Nominee Shareholders, fake shareholding, and borrowed-name shareholding, with the following industries as key targets of scrutiny:

  • Real estate
  • Restaurants
  • Tourism
  • Services

The government now further requires shareholders to prove that their capital genuinely comes from themselves. As a result, the old practice of “having a friend hold shares on your behalf” is no longer a safe approach — if identified as a nominee arrangement, the company may be forcibly shut down, and the foreign director may also face criminal liability.

Practical reminder:

If you want full control of your company, there’s no need to take the risky route: going through IEAT/BOI/FBL allows you to legally hold 100% of the shares. If you want to find a local partner, you should find a Thai shareholder who genuinely invests capital and genuinely participates, backed by a formal shareholders’ agreement.

Q 04　As the owner, can I skip getting a work permit?

» No, this is a common misunderstanding.

Many people assume that “I’m the owner, so I don’t need a Work Permit” — but this is not the case. As long as a foreigner engages in activities that fall under the definition of “work” in Thailand, such as employment or management, they generally need to obtain a work permit as required by regulations, or meet the relevant exemption qualifications.

Q 05　What taxes does a company need to pay? Is the tax burden heavy?

» SMEs actually enjoy quite a few benefits.

Thailand is fairly friendly to SMEs. Companies that qualify (paid-up capital ≤ 5 million baht, annual revenue ≤ 30 million baht) are eligible for progressive preferential tax rates:

Company Net Profit (Baht) Applicable Tax Rate
Up to 300,000 0%
300,000 – 3,000,000 15%
Over 3,000,000 20% (also the standard rate for general companies)

Q 06　Does a Thai company have to hire an accountant?

» Strongly recommended, yes.

After a Thai company is established, even without revenue, it generally still needs to legally handle the following matters:

  • Bookkeeping
  • Tax filing (including monthly VAT and withholding tax filings)
  • Submitting annual financial statements
  • Annual audit (applicable to most limited companies, must be reviewed by a licensed Thai accountant)

For many foreigners, the real problems don’t arise from setting up the company, but from failing to file properly afterward. Engaging a local accounting firm from day one allows you to focus on your business while avoiding the penalties and credit risks that come with missed filings.

Q 07　Which industries currently welcome foreign investment the most?

Answer: Technology, digital, energy, and precision manufacturing are on the rise.

Thailand is actively attracting high-value foreign investment, and the direction is clear, viewed from two levels:

1. Industries newly opened up in 2026

Thailand has removed about 10 business activities from the restricted list, allowing foreign investors to hold 100% of shares without applying for an FBL, including:

  • Software development — a major benefit for SaaS, apps, digital agencies, and IT service providers.
  • Telecommunications services (Type 1) and various financial-related businesses (treasury centers, derivatives, etc.).

2. BOI key incentive industries

Successfully obtaining BOI approval not only allows 100% foreign sole ownership, but also comes with corporate income tax exemptions, import duty reductions, and relaxed employment ratio requirements. Key incentive areas include:

  • Energy: clean energy, renewable energy, EVs and charging infrastructure, as well as supporting power for data centers.
  • Precision and advanced manufacturing: aerospace components, automation equipment, PCBs and electronic components — precisely where Taiwanese-invested companies are most competitive.
  • High-tech and digital software: AI, cloud, data centers.
  • Medical and biotechnology.

Q 08　What is the biggest risk for foreigners setting up a company in Thailand?

» The risk lies “after” incorporation.

According to sharing from Reddit, entrepreneurship forums, and business founders, the real risk usually isn’t the “company registration” itself, but rather subsequent operations and compliance.

The most commonly mentioned issues include:

  • Choosing the wrong shareholders
  • Choosing the wrong agent
  • Lack of tax planning
  • Insufficient preparation for opening a bank account
  • Poorly designed company structure
  • Mismatch between registered business scope and actual operations
  • Work permits, visas, and company planning not synchronized
  • Subsequent accounting and annual filings being neglected

Many people treat company formation as the finish line, but the real beginning actually starts after the company is established.

Advisor’s Perspective

As a team that has long assisted Chinese-speaking and international investors in setting up companies in Thailand, MaxRealty’s observation is that Thai regulations in recent years have been rapidly moving toward being “more transparent, more digitalized, and placing greater emphasis on compliance.”

Starting in 2026, company registration has fully transitioned to the DBD Biz Regist online platform, scrutiny of nominee shareholders has tightened, and tax and social security data are being cross-checked — all pointing to the same thing: those who “get the structure right” now have an even greater advantage than before.

The one thing we most often remind clients is: don’t just ask “what’s the lowest amount needed to set up a company” — first ask “will this structure still hold up three years from now.” A design that takes shareholding, taxation, work permits, and bank account opening into account together is the real key to reducing risk.

Conclusion: Setting Up a Company Isn’t Hard — Choosing the Right Structure from the Start Is

Thailand remains one of the most attractive investment markets in Southeast Asia, but its regulations are developing in a direction that is more transparent, more digitalized, and places greater emphasis on compliance. For foreign investors, rather than starting by only asking “what’s the lowest amount needed to set up a company,” it’s more important to first clarify the following four questions:

  • Is my industry restricted under the Foreign Business Act?
  • Do I qualify for BOI or other pathways to 100% foreign ownership?
  • Does the company structure account for control, taxation, and work permit needs together?
  • Have subsequent accounting, tax filing, annual audits, and compliance been factored into the plan?

The right company structure not only allows the company to be established smoothly, but also reduces future risks in operations, bank account opening, visas, taxation, and fundraising.
