Setting up a business abroad comes with a fair share of paperwork, legal hurdles, and regulatory questions, and Thailand is no different. If you are a founder, CEO, or expanding business looking at Southeast Asia, LLC company registration in Thailand is likely one of the first things on your checklist. Thailand’s growing economy, strategic ASEAN location, and business-friendly policies make it an attractive destination for both startups and established companies.

The guide explains how to register an LLC company in Thailand: what the equivalent business structure looks like locally, what documents you need, and what tax obligations there are. Whether you are setting up your first international entity or adding Thailand to a growing portfolio of markets, this guide gives you a clear, practical path forward.

Key Highlights

  • Thailand does not have a structure called an “LLC”; the closest equivalent is the Private Limited Company (Co., Ltd.), governed by Thailand’s Civil and Commercial Code, offering the same liability protection.
  • Foreign founders can register a company in Thailand, but ownership is typically capped at 49% under the Foreign Business Act (FBA), with exceptions available through BOI promotion.
  • The registration process involves name reservation, filing a Memorandum of Association, a statutory meeting, and registration with the Department of Business Development (DBD).
  • Corporate income tax is set at 20% on net profits, with reduced rates for small companies, and VAT registration is required once annual revenue crosses 3 million baht annually.
  • Ongoing compliance includes annual tax filings, monthly VAT returns, and social security registration for employees within 30 days of the first hire.

Can You Register an LLC in Thailand?

Thailand does not use the term “LLC” in its legal framework. The closest equivalent to a limited liability company Thailand offers is the Private Limited Company, locally known as Borisat Chamgat (บริษัทจำกัด). This structure, governed by Section 1096 of Thailand’s Civil and Commercial Code, provides the same core benefit: shareholders are liable only for the capital they have invested. It is the most popular business structure for both Thai nationals and foreign investors looking to establish a legal entity in the country.

Foreign entrepreneurs can form a company in Thailand, but there are important ownership rules to understand. Under the Foreign Business Act (FBA), foreign ownership is generally limited to 49% in most sectors, meaning Thai nationals must hold at least 51% of shares. That said, there are legal pathways to achieve 100% foreign ownership, particularly through promotion by the Board of Investment (BOI) or by operating in sectors not restricted by the FBA.

Advantages of Forming an LLC in Thailand

There are solid reasons why Thailand continues to attract international entrepreneurs looking to form a limited liability company. The structure offers clear legal benefits alongside some lesser-known commercial advantages that are worth knowing before you commit.

Benefits of forming an LLC (Co., Ltd.) in Thailand:

  • Limited liability protection: Shareholders are only responsible for unpaid share amounts. Your personal assets are kept separate from business debts.
  • Separate legal entity: The company can enter contracts, own property, and sue or be sued in its own name, independent of its shareholders.
  • Foreign-friendly ownership pathways: BOI-promoted companies can achieve 100% foreign ownership in priority sectors such as advanced manufacturing, digital services, clean energy, and logistics.
  • Access to BOI incentives: BOI-promoted businesses can receive corporate income tax exemptions for up to 8 years, import duty waivers on machinery, and reduced rates on raw materials.
  • Eastern Economic Corridor (EEC) benefits: Companies investing in the EEC, Thailand’s flagship special economic zone, can access additional tax reductions, fast-track permits, and infrastructure support.
  • Double tax treaties: Thailand has signed over 60 double taxation agreements (DTAs), which reduce withholding tax exposure for cross-border dividend payments, interest, and royalties.
  • Work permit eligibility: Once registered, the company can sponsor work permits for foreign employees, with 2 million THB in registered capital required per permit.

These benefits make LLC formation in Thailand attractive for startups, regional holding entities, and international brands expanding into Southeast Asia.​

Steps to Register an LLC in Thailand

The practical process for LLC company registration in Thailand centers on registering a company limited with the Department of Business Development (DBD). Since 2026, the DBD Biz Regist online system has become the primary channel, with fully digital submissions and e-signatures.

Step 1: Decide on structure, shareholders, and activities

Confirm that a private limited company is the right structure and check whether your planned business activities fall under the Foreign Business Act. If foreign shareholders will hold 50% or more, you may need a Foreign Business License, BOI promotion, or a treaty route.

Key decisions include:

  • Number of shareholders and shareholding split
  • Intended business objectives as they will appear in the Memorandum of Association
  • Whether BOI promotion or other incentives are realistic for your sector

Step 2: Reserve the company name online

You must reserve your proposed company name through the DBD name reservation system, now integrated into DBD Biz Regist. Names must be unique, comply with naming rules, and end with “Limited” or “Co., Ltd.” for a private company.

Good practice is to submit three alternative names in order of preference and avoid terms restricted by regulation, such as words implying royal patronage.

Step 3: Prepare the Memorandum of Association (MOA)

Promoters prepare and file an MOA stating the name, registered office, objectives, capital, and share structure. Thai law requires at least three individual promoters for a private limited company, each subscribing to at least one share.​ The MOA is filed electronically with the DBD, along with promoter details and evidence of name reservation.

Step 4: Hold the statutory meeting

Once the share capital has been subscribed, the promoters call a statutory meeting to adopt the Articles of Association, appoint directors, and approve the share payment structure. This meeting also confirms the registered office and may appoint an auditor.​ Minutes of the statutory meeting are required for the final registration filing and must be uploaded via DBD Biz Regist.

Step 5: Register the company with the DBD

The directors apply to register the company as a juristic person with the DBD within the required timeline after the statutory meeting. All applications and supporting documents now move through the online DBD Biz Regist system, which replaces older e-Registration and most paper filings.

The DBD issues a Certificate of Incorporation, a company affidavit, and a 13-digit registration number, which also serves as the tax ID. Processing often takes only a few business days once documents are complete, though new digital systems can cause delays during busy periods.

Step 6: Register for corporate tax, VAT, and social security

A newly formed LLC in Thailand must register for corporate income tax with the Revenue Department, usually by using the juristic person number issued by the DBD. VAT registration is required once annual turnover exceeds 1.8 million Thai baht, or earlier on a voluntary basis.

If you hire employees, you must also register the company and workers with the Social Security Office for payroll contributions.​

Practical tips for forming an LLC

  • Double-check spellings and Thai-language versions of names and addresses before submitting forms to avoid avoidable rejections.
  • Upload bank evidence for share payments quickly when required for higher capital, as DBD rules set specific deadlines.
  • Keep all shareholder and director passports and Thai ID cards valid and legible, as unclear scans often trigger follow-up questions.

Documents Required for LLC Registration in Thailand

The document set for LLC formation in Thailand has become more standardised with online registration, but requirements can still vary slightly by case.

Typical documents include:

  • Passport or Thai ID copies for all promoters, shareholders, and directors, often with certified signatures.
  • Completed MOA, Articles of Association, and statutory meeting minutes in Thai, in the DBD-approved formats.
  • Evidence of the registered office, such as a lease agreement and landlord consent letter, if you rent the premises.
  • Bank confirmation that directors have received share capital payments for higher-capital companies, submitted within the DBD deadline.
  • For payments in property instead of cash, a consent letter from the property owner, and later proof of transfer or asset schedules.​

Foreign founders forming an LLC company in Thailand may also need notarised passport copies, translations, or proof of overseas fund transfers for capital injections. Many use local law firms or corporate service providers that can handle notarisation and online submission to the DBD Biz Regist system.

Tax Obligations After LLC Registration in Thailand

Once your LLC company registration in Thailand is complete, you step into a set of ongoing tax responsibilities. Thailand’s tax system is administered by the Revenue Department under the Ministry of Finance, and compliance is not optional. Missing deadlines or misfiling carries real financial penalties.

Key tax obligations for a Thai Private Limited Company:

Corporate Income Tax (CIT):

  • Standard rate: 20% on net profits
  • Reduced rates for small companies (paid-up capital below THB 5 million): 0% on profits up to THB 300,000; 15% on profits between THB 300,001 and THB 3 million; 20% on profits above THB 3 million
  • Annual CIT return (Form PND 50) must be filed within 150 days after the accounting period ends (158 days if filing via e-Filing)
  • A semi-annual prepayment (Form PND 51) is due within two months after the first six months of the accounting year.

Value-Added Tax (VAT):

  • Currently 7% on most goods and services (reduced from the standard 10%, extended until September 30, 2026, per PWC Thailand and Revenue Department updates)
  • Required once annual revenue exceeds THB 1.8 million
  • Monthly VAT returns must be filed by the 15th of each following month.
  • Late returns carry a penalty of THB 2,000 per return.

Withholding Tax:

  • Companies must withhold tax on salary payments, dividends, interest, and royalties, and remit to the Revenue Department within seven days of the month following payment.

Social Security Contributions:

  • Employers contribute 5% of the employee’s salary (capped at THB 750/month per employee) to the Social Security Fund.

Annual Audit:

  • All Thai limited companies must have their accounts audited by a Certified Public Accountant (CPA) and submit audited financial statements annually.

Commonly overlooked obligations:

  • Maintaining accounting records in Thai (or certified Thai translations) for a minimum of five years.
  • Transfer pricing documentation if your company transacts with related parties.

Thailand has signed over 60 double tax treaties, which can reduce withholding tax on dividends (often from 10% to 5%) and interest payments for qualifying foreign investors.
