Thailand – Self-Employment

How does self-employment work for expats in Thailand?

Thailand does not offer a straightforward self-employment registration route for foreign nationals comparable to, say, the sole trader system in the UK or Germany. Under Thai law, any work performed by a foreigner requires a valid work permit, with the narrow exception of urgent tasks lasting fifteen days or fewer. This sets a stricter starting point than many other countries, where self-employed individuals can begin trading simply by notifying the tax authority.

Foreign nationals who want to work in Thailand must secure both a Non-Immigrant B visa and a work permit. Oversight of this process falls to the Immigration Bureau and the Employment Department within the Ministry of Labour. For expats intending to work through their own business — the most widely used approach — this means forming a Thai legal entity first, which can then act as the work permit sponsor.

Work permit compliance in Thailand is governed by the Foreigners’ Working Management Decree B.E. 2560 (2017) and 2561 (2018). The concept of an independent sole trader, familiar in many European or Latin American contexts, has no direct equivalent for foreign nationals under Thai law. In practice, the legally recognised path to self-employment almost always runs through a properly registered company structure.

Operating without a valid work permit is a breach of Thai law and can result in fines of up to 100,000 THB, forced removal from the country, or future entry bans. These consequences apply whether income originates from Thai or overseas clients, making it essential to have your legal status formalised before undertaking any work-related activities on Thai soil.

What are the different self-employment and business structures available in Thailand?

Business structures in Thailand fall under the supervision of the Department of Business Development (DBD). A range of entity types is available, and those most relevant to expats include sole proprietorships, ordinary partnerships, limited partnerships, and private limited companies.

Sole proprietorships and unregistered ordinary partnerships do not require formal registration. For foreign nationals, however, these structures are generally unworkable — they confer no corporate status, and without corporate status there is no mechanism to sponsor a work permit. As a result, these forms are almost exclusively used by Thai nationals.

The private limited company is the most widely favoured structure among foreign investors. It is broadly comparable to a private limited company in the UK, a GmbH in Germany, or a Société à responsabilité limitée (SARL) in France — it creates a clear separation between the personal assets of the owners and the liabilities of the business, and it forms the basis on which a work permit can be obtained.

The critical legal constraint on private limited companies is the Foreign Business Act, which restricts foreign ownership of an ordinary Thai limited company to 49.99% for most restricted business activities. This typically means a foreign founder must partner with Thai shareholders who hold the majority of shares. These arrangements must be genuine — so-called “nominee” shareholding, where Thai nationals hold shares on behalf of a foreigner without real ownership, is illegal under Thai law.

Full foreign ownership of a Thai company — up to 100% — is possible if the chosen business activity falls outside the restrictions listed in the Foreign Business Act, or if the founder obtains a Foreign Business Licence (FBL) or secures an exemption through mechanisms such as BOI promotion.

A representative office enables a foreign company to establish a presence in Thailand restricted to promotional and marketing functions. A branch office, by contrast, allows a foreign company to conduct actual commercial activities in Thailand on behalf of the parent entity. Both options are more relevant to established multinationals expanding into the Thai market than to individual expat entrepreneurs starting from scratch.

Joint ventures offer another avenue for foreign entrepreneurs entering Thailand. Partners collaborate while retaining their separate identities, with their respective roles, capital contributions, and liability exposure defined by their agreement and applicable Thai law.

How do you register as self-employed in Thailand?

Because sole trader registration is not a viable option for foreign nationals, “becoming self-employed” in Thailand in practice means incorporating a company and then securing a work permit through that entity. The steps below describe the standard process for an expat establishing a Thai limited company and work permit for the first time. Always verify current fees and requirements with the Department of Business Development (DBD) and the Ministry of Labour.

1. Obtain a Non-Immigrant B Visa. A valid Non-Immigrant B Visa must be in place before a work permit application can be lodged. The fee is 2,000 THB for a single-entry visa with three-month validity, or 5,000 THB for a multiple-entry visa with one-year validity (as of 2025). Applications are made at a Royal Thai Embassy or Consulate in your country of residence.
2. Reserve a company name. Follow the name reservation guidelines set out by the Department of Business Development (DBD) within the Ministry of Commerce. Submit at least two or three alternative names to maximise the chances of approval, then proceed with the reserved name once confirmed as available.
3. Prepare the Memorandum of Association (MOA) and Articles of Association (AOA). Required documentation includes a completed company registration form bearing original signatures from all shareholders and directors, copies of the MOA and AOA, and minutes from the statutory meeting at which both documents were adopted.
4. Meet minimum capital requirements. The minimum registered capital to establish a limited company in Thailand is 50,000 THB. If the company intends to employ foreign nationals, the minimum rises to 2 million THB per foreign employee (as of 2025). Confirm the current threshold with the DBD prior to filing.
5. Register the company with the DBD. Thailand’s DBD further streamlined its registration process in 2025, enabling fully digital applications with e-signature functionality. Professional service fees for registration assistance typically fall between 30,000 and 60,000 THB (as of 2025); contact service providers directly for up-to-date quotations.
6. Register the company on the e-Work Permit portal and apply for your work permit. The employer registers the company on the e-Work Permit portal and verifies identity through the ThaiID App. The foreign employee then creates a separate account and uploads the required documents. Both parties submit their respective files, and the BT.32 online application form is completed with a fee of 3,000 THB for a one-year permit (as of 2025).
7. Book a biometric appointment and collect your permit. Arrange biometric verification and card issuance at an authorised service centre. Provided all documentation has been verified, the digital work permit card can be issued on the same day.
8. Renew annually. Work permit renewals must be submitted at least 30 days before the permit’s expiry date. Permits are issued on an annual basis and must be kept current.

Processing typically takes between 7 and 10 business days in Bangkok, with somewhat longer timelines in regional provinces (as of 2025). Always check current turnaround times with the Ministry of Labour, as these may change.

How do you set up a company in Thailand as an expat?

For most expat entrepreneurs, incorporating a private limited company is the essential first step towards working legally in Thailand. The process is governed by the Civil and Commercial Code and administered by the Department of Business Development (DBD). The steps below describe the standard incorporation procedure for a Thai limited company; always confirm the latest requirements directly with the DBD.

1. Confirm your business activities under the Foreign Business Act (FBA). The FBA is the primary legislation governing foreign participation in the Thai economy. Certain activities in services, retail, and agriculture are restricted or prohibited for companies with majority foreign ownership. Before proceeding, determine whether your intended activity requires a Foreign Business Licence or qualifies for a BOI exemption.
2. Decide on your ownership structure. The most common arrangement is to form a Thai Limited Company in which Thai nationals hold at least 51% of the shares. Such a company is treated as “Thai” and is not subject to the FBA’s restrictions. It is vital to ensure that any Thai shareholding represents a genuine equity stake rather than an illegal nominee arrangement.
3. Reserve your company name with the DBD. The name must be unique and comply with DBD naming conventions. Name reservation applications can now be submitted through the DBD’s online portal.
4. File the Memorandum of Association (MOA). The company must have a minimum of two shareholders and one director. At least two promoters must sign the MOA and submit it to the DBD for approval.
5. Hold the statutory meeting and register the company. The statutory meeting serves to adopt the AOA, appoint the board of directors, and authorise the subscription of shares. Following this meeting, the company is formally registered with the DBD.
6. Meet capital requirements. In most cases a minimum registered capital of THB 50,000 applies; companies wishing to employ foreign nationals must hold THB 2 million per foreign employee (as of 2025). Verify these thresholds with the DBD for the most current figures.
7. Register for tax and VAT. Companies must pay corporate income tax and submit filings to the Revenue Department on schedule. Businesses generating annual revenue in excess of 1.8 million THB must also register for VAT. Refer to the Revenue Department for the current registration threshold.
8. Apply for work permits for foreign staff. Once the company is incorporated and satisfies capital requirements, foreign directors and employees may apply for work permits through the e-Work Permit system (see the registration steps in the previous section).

Cutting corners on professional advice risks non-compliance with the Foreign Business Act or BOI conditions. Budgeting for reputable legal and corporate secretarial services from the outset will help you structure the business correctly and avoid costly fines, rework, or forced dissolution later.

Once registered, the company must maintain monthly bookkeeping covering tax filings and social security contributions, as well as an annual statutory audit. Build these recurring costs into your first-year budget to keep your operations on the right side of the law.

Can you work as a digital nomad in Thailand?

Thailand introduced a dedicated visa pathway for digital nomads in 2024. The Destination Thailand Visa (DTV) launched that year as a long-awaited option for location-independent professionals and has since become one of the more flexible long-stay visas available in the region for remote workers.

The DTV is a five-year, multiple-entry visa crafted for professionals whose work is not tied to a fixed location. It permits stays of up to 180 days per entry, with the possibility of a single extension each year. The extension fee is 1,900 THB and must be processed at a Thai immigration office (as of 2025). Always confirm the current fee with the Thai Immigration Bureau.

The application fee for the DTV is 10,000 THB (as of 2025). To be eligible, applicants must show financial stability through savings of at least 500,000 THB (approximately $14,500 USD). Unlike some comparable programmes — such as Indonesia’s, which requires annual earnings above $60,000 — Thailand’s DTV imposes no minimum income figure, relying instead on the savings threshold and evidence of remote work status.

Applicants must be at least 20 years old. Whether you work as a freelancer, run your own business, or are employed by a company based outside Thailand, you will need to demonstrate that your work is conducted for non-Thai entities. Acceptable supporting evidence includes employment contracts, company registration documents, or a professional portfolio accompanied by client agreements.

It is important to understand that the DTV functions as a special category of tourist visa. Holders are prohibited from obtaining a Thai work permit and may not work for Thailand-based companies or take on freelance assignments for Thai clients. Anyone who wishes to work for Thai clients or draw a salary from a Thai company must instead apply for a Non-Immigrant B visa and a standard work permit.

In November 2025, Thailand announced stricter enforcement measures: travellers who make more than two visa runs in a given year may now be refused entry. Immigration officers are actively reviewing travel histories to identify individuals residing in Thailand long-term on a series of tourist entries. This applies at all points of entry — international airports, land border crossings, and sea routes alike. For digital nomads, relying on repeated visa runs is no longer a viable strategy.

The Long-Term Resident (LTR) Visa, valid for up to 10 years, is another compelling option for those in well-paid roles at foreign companies. Its “Work from Thailand” category provides complete exemption from Thai tax on foreign-sourced income. Eligibility generally requires an annual income of around $80,000 and at least five years of relevant professional experience, among other criteria (as of 2025). Consult the BOI’s LTR portal for full and current eligibility criteria.

What taxes and social contributions apply to self-employed expats and business owners in Thailand?

Tax administration in Thailand is handled by the Revenue Department. The tax year runs from 1 January to 31 December, and annual tax returns must be filed by 31 March. No extensions are granted by the Revenue Department. This is a tighter deadline than in many other countries — self-employed individuals in the UK, for instance, have until 31 January to file online, while in Australia certain lodgements through tax agents can be deferred until May.

Thailand operates a progressive income tax system. The first 150,000 THB of income is tax-free; the band from 150,000 to 300,000 THB is taxed at 5%; from 300,000 to 500,000 THB at 10%; and so on, rising incrementally to a ceiling rate of 35% on income above four million THB (as of 2025). Verify the current bands with the Revenue Department.

Following amendments to Thailand’s tax rules in 2024, any foreign income transferred into Thailand is now subject to tax — but only for individuals who qualify as Thai tax residents, meaning those who spend 180 days or more in Thailand within a single calendar year. This differs from PAYE-style employment taxation common in many countries, where tax is deducted automatically at source; resident self-employed individuals in Thailand must proactively file their returns and settle any tax owed.

Tax residents may also be exempt from Thai tax on certain income if their home country has a Double Tax Agreement (DTA) with Thailand, preventing the same income from being taxed in both jurisdictions. Thailand has concluded DTAs with over 60 countries. The Revenue Department’s website maintains a current list of treaty partners.

Thai companies are required to pay corporate income tax and submit filings to the Revenue Department in accordance with the prescribed schedule. The standard corporate income tax (CIT) rate is 20% on net profits, though smaller companies with paid-up capital not exceeding 5 million THB and annual revenue below 30 million THB may qualify for reduced rates — confirm the current thresholds with the Revenue Department.

Once a company is in operation, it faces mandatory monthly bookkeeping obligations encompassing tax filings and social security contributions, as well as an annual statutory audit. Thailand’s Social Security Office (SSO) requires both employers and employees to contribute a percentage of declared salary each month. As a company director drawing a salary, you will typically be subject to these contributions. Check the Social Security Office for the current contribution rates and applicable salary caps.

In total, Thailand’s personal income tax system comprises eight bands, rising in 5-percentage-point increments from 0% to 35% (as of 2025). Always seek guidance from a qualified Thai tax adviser and refer to the Revenue Department for the most up-to-date rates before filing your return.

Are there any incentives, grants, or programmes to encourage expat entrepreneurs in Thailand?

Thailand has put in place several government-backed schemes to draw foreign entrepreneurs and investors, positioning itself as one of Southeast Asia’s more proactive countries in terms of foreign business incentives. The principal body overseeing these programmes is the Thailand Board of Investment (BOI).

The BOI offers a range of benefits to qualifying businesses, including the right to 100% foreign ownership in specific promoted activity categories. For businesses that deliver desired technology transfers or measurable economic benefits, BOI registration can provide a legitimate exemption from the ownership restrictions of the Foreign Business Act.

Tax benefits under BOI promotion include corporate income tax holidays for a defined period, relaxed requirements around work permit numbers for foreign staff, the absence of foreign employee quotas, and the right to own land. High-technology activities deemed important to Thailand’s development may qualify for a five-year corporate income tax exemption, while activities with lower technology content that add value to domestic resources and supply chains may receive a three-year exemption (as of 2025).

The Thai government is actively developing strategic zones such as the Eastern Economic Corridor (EEC) and supporting investment through the Industrial Estate Authority of Thailand (IEAT) to attract foreign capital in high-technology sectors as part of the Thailand 4.0 initiative. Companies establishing operations within EEC zones — encompassing Chonburi, Rayong, and Chachoengsao provinces — benefit from additional perks including enhanced infrastructure support.

The SMART Visa targets highly skilled professionals in technology, science, and business — particularly those driving innovation or startup growth in Thailand. It carries a validity of up to four years. As of 2025, fast-track SMART Visa processing is available for executives, specialists, and startup founders through BOI-promoted channels.

BOI-promoted companies are also eligible to apply for a Foreign Business Certificate, which permits them to operate without the need for a separate Foreign Business Licence. Additional advantages of BOI status include tax incentives, land ownership rights, and a more streamlined visa and work permit process for foreign employees.

American citizens and US-incorporated businesses benefit from a bilateral arrangement with Thailand. The US–Thailand Treaty of Amity permits American entities to engage in most business activities on the same footing as Thai nationals, effectively exempting them from many of the restrictions under the Foreign Business Act. No equivalent treaty currently exists for most other nationalities, though this should be confirmed with the US Embassy or a qualified legal adviser.

What are the practical challenges of being self-employed or running a business in Thailand?

Even before the company registration process begins, engaging a qualified lawyer is advisable. Much of Thailand’s legal and regulatory landscape is documented in Thai, and official forms, registration portals, and government communications are not always reliably translated into English. Selecting a reputable law firm to clarify regulations, obtain licences, and advise on compliance is not merely a convenience for most expats — it is a practical necessity.

Thai administrative processes are largely conducted in the Thai language, and unlike countries such as Singapore — where government services are comprehensively available in English — navigating Thai bureaucracy without a local lawyer or accountant is challenging and leaves significant room for costly error.

Thailand requires a minimum paid-up capital of THB 2 million for each foreign work permit. This is not a nominal or paper requirement — it represents a genuine cash injection that the business must make before any expatriate staff can be hired. Compared to European sole trader registration, which in most countries requires no minimum capital at all, this represents a substantial upfront financial commitment.

Opening a Thai corporate bank account for newly incorporated companies can be a slow and document-intensive process. Banks typically require certified company documents, director identification, a company seal, and in many cases an in-person branch visit. Some institutions impose stricter conditions on companies with majority foreign ownership. Engaging a local accountant or corporate services provider can help to streamline this process considerably.

Invoicing overseas clients while based in Thailand is technically uncomplicated — invoices are issued in the name of the Thai company or, where applicable, in the individual’s name under their work permit. However, those operating under a DTV and working exclusively for foreign clients should maintain detailed records demonstrating that no income arises from Thai sources, since the DTV explicitly prohibits any commercial engagement with Thai entities, even on a short-term or occasional basis.

In 2025, Thailand’s Ministry of Labour launched an e-Work Permit system to replace the traditional physical “blue book” work permit. The digital transition is intended to simplify applications and improve compliance monitoring. However, as of early 2025, the rollout had not been completed and processing times were running slower than under the legacy system, with no confirmed date for full implementation. Monitor the Ministry of Labour website for the latest updates.

A frequent and serious mistake is commencing work before the work permit has been formally issued. Doing so — even while an application is actively being processed — constitutes illegal employment under Thai law. Always wait for written confirmation of approval before beginning any activities covered by your work permit.

Frequently asked questions

Can I be both employed and self-employed at the same time in Thailand?

In Thailand, work permits are tied to a specific employer, role, and geographic location. The permit remains valid only for that particular position and province. If you change employer or move to a different location, a new work permit is required. Running a separate business while holding a work permit from another employer is not permitted under standard arrangements — each work activity ordinarily requires its own work permit issued by the relevant sponsoring entity. Seek advice from a qualified Thai labour lawyer for guidance on your individual circumstances.

Can I invoice foreign clients from Thailand without a work permit?

The DTV, introduced in 2024 for digital nomads, freelancers, and remote professionals, authorises work performed exclusively for non-Thai companies or clients. A freelancer based in Thailand who services clients in Europe, for example, may do so lawfully under a DTV, provided no income is derived from Thai sources. If you are not holding a DTV or LTR visa, billing any clients — whether Thai or foreign — without a valid work permit is generally treated as illegal employment under Thai law.

What happens to my business if my visa status changes?

Your Thai company registration is unaffected by changes to your personal visa status. However, your work permit — which depends on the validity of the underlying visa — will cease to be valid if the visa lapses. Work permits must be renewed each year before they expire, and any changes to your role, employer, or working location must be reported to the Ministry of Labour, with the permit amended accordingly. If your visa lapses, all work-related activities must stop immediately while the visa situation is resolved.

Do I need a local Thai partner to own a company in Thailand?

The most common structure involves Thai nationals holding at least 51% of the shares, which classifies the company as “Thai” and places it outside the scope of the Foreign Business Act’s restrictions. That said, 100% foreign ownership is achievable where the business activity does not fall within the FBA’s restricted categories, or where the founder secures a Foreign Business Licence or an exemption through BOI promotion. Professional legal advice is essential when choosing and implementing your ownership structure.

How is foreign income taxed if I live in Thailand long-term?

Following the 2024 amendments to Thailand’s tax rules, foreign income remitted to Thailand is subject to Thai tax — but only for individuals who qualify as tax residents, defined as those who spend at least 180 days in Thailand during a calendar year. You may be exempt from Thai tax if your country of origin has a Double Taxation Agreement with Thailand, preventing the same income from being taxed in both countries. Consult the Revenue Department and a qualified tax adviser for advice specific to your situation.

Is the BOI route worth it for a small startup?

Although securing BOI promotion involves higher upfront advisory costs, the long-term benefits — including tax holidays and the ability to hold 100% foreign ownership — can generate significant savings over time. Reduced requirements for hiring foreign staff are a further advantage for BOI-status companies. For smaller startups, however, the complexity and cost of a BOI application may outweigh these benefits; forming a non-BOI Thai limited company with majority Thai shareholders is often a simpler and more affordable starting point. A qualified corporate lawyer can help you weigh the options.

Do I need to register for VAT as a self-employed person in Thailand?

VAT registration becomes mandatory in Thailand once annual revenue exceeds 1.8 million THB (as of 2025). Below this threshold, registration is voluntary but may be commercially advantageous if you deal with VAT-registered businesses that wish to reclaim input tax. The current standard VAT rate in Thailand is 7% (as of 2025), reduced from the statutory rate of 10% — verify the prevailing rate with the Revenue Department, as temporary reductions have been extended on multiple occasions.

Can I open a Thai bank account as a self-employed expat or company owner?

Opening a personal Thai bank account generally requires a valid non-tourist visa — such as a Non-Immigrant B — together with a work permit or company documentation. DTV holders are not eligible to open a Thai bank account, which represents a practical limitation for digital nomads needing to manage finances locally. Corporate bank accounts require certified company documents, director identification, a company seal, and a registered business address. Engaging a local corporate services firm can help to accelerate and simplify this process.
