AI regulation in Thailand 2026: what applies and the draft AI Act

Treepob Tiangtrong (Champ) · Founder and CEO, TRAINIAC · 4 Nov 2026

TL;DR As of 18 Oct 2026, Thailand has no AI-specific law in force; the PDPA binds. The PDPC Office's AI guideline (final 7 Oct 2026, Royal Gazette 2 Nov 2026) has no legal force. Consultation on ETDA's draft AI Act closed 14 Aug 2026, with no Cabinet resolution found. Not legal advice.

As of 18 October 2026, Thailand has no AI-specific law in force. What already binds organisations is the Personal Data Protection Act B.E. 2562 (PDPA) and existing law such as consumer protection, copyright and civil liability. The latest change: the Office of the Personal Data Protection Committee (PDPC Office, สคส.) published the final version of its AI personal data protection guideline on 7 Oct 2026, and it was published in the Royal Gazette (ราชกิจจานุเบกษา) on 2 Nov 2026. The document itself says it has no legal force. But it shows clearly how the regulator views AI use. For example, entering personal data into public AI is high risk. Meanwhile, public consultation on the draft Artificial Intelligence Act (ร่าง พ.ร.บ. ว่าด้วยปัญญาประดิษฐ์) of the Electronic Transactions Development Agency (ETDA, สพธอ.) closed on 14 Aug 2026, and we have found no Cabinet resolution on it yet. The draft proposes risk-based tiers, joint liability without proof of fault, and fines of THB 1–5 million. The financial sector has had a Bank of Thailand (BOT, ธปท.) policy guideline on AI risk since 12 Sep 2025. This article has a status table for each document, a timeline of the draft law, what the draft contains, and a checklist that links each task to its source document.

This article is a practical overview to help you prepare. It is not legal advice. The status of draft laws can change. Check the latest status, and consult your legal adviser about your own case.

Having no AI-specific law does not mean there is a legal vacuum. The PDPA already binds every use of AI that touches personal data, and it carries real penalties. The duties are set out in PDPA and AI use in organisations.

The PDPC Office's final AI guideline

The PDPC Office opened the draft for comment on 19–25 Feb 2026. It published the final version 1.0, 80 pages long, on its website on 7 Oct 2026. The guideline was then published in the Royal Gazette, vol. 143, special issue 261 ง, on 2 Nov 2026. The Royal Gazette version is still version 1.0, and it still states that it "has no legal force and no binding effect in the consideration of offences". But it is the regulator's own explanation of how the PDPA applies to AI work. These are the points that most affect organisations that use AI in daily work.

  • Entering personal data into public generative AI is high risk. It may amount to unlawful disclosure of data. The guideline recommends a policy that bans such input, or using enterprise versions backed by a data protection agreement.
  • Bar staff from connecting personal AI tools to company data, and state in the contract that the AI provider may not use the organisation's data to train models without permission.
  • High-risk work needs human oversight by someone who can intervene in, review or stop an AI decision at once.
  • If people abroad can access the data, it may count as a cross-border data transfer, which must comply with sections 28 and 29 of the PDPA.

The 6–24 month figure in some news reports is Rajah & Tann's estimate of how long the law will take to be promulgated and take effect. It is not a grace period written into the draft

In practice, the draft is unlikely to take effect in 2026. Once it is promulgated, the July 2026 draft gives 180 days to prepare for some parts.

What the July 2026 draft proposes

TopicWhat the draft proposesWhat it means for organisations that use AI
ScopeApplies to developing or using AI that affects people in Thailand, even if the provider is abroad. Personal use by individuals is excludedThai organisations that use foreign tools are still in scope
Prohibited AISubliminal manipulation techniques, and wide-scale discrimination from processing unrelated data. The committee can add more by noticeCheck that none of your systems falls into these
High-risk AISystems designated by royal decree (พระราชกฤษฎีกา) in security, health, environment, energy, telecommunications, transport and public utilities. A royal decree may also require other systems to be notified, registered or licensedThe actual list must wait for the royal decree
Duties of organisations that deploy high-risk systemsHave a risk management system, follow the provider's instructions, assign competent human oversight, keep logs for at least 6 months, and report unexpected risksName who is responsible and start keeping logs today
TransparencyDevelopers of systems that create images, audio or video must embed machine-readable markings. Anyone who releases certain AI content to the public, such as content on elections, investment, food and drugs, or impersonation, must disclose it, and platforms must label itLabel AI-generated content that you publish externally
Foreign providersMust appoint a coordinator or representative in ThailandAsk the providers you use how they are preparing
Civil liabilityJoint liability without proof of intent or negligence. Defences are limited to force majeure, the injured party's own act, or following an official's orderReview how liability is shared in your contracts with providers
PenaltiesAdministrative fines of THB 1–5 million depending on the type of violation, and a court can be asked to order a service suspended or to order internet service providers to block itThe cost of non-compliance is high enough to prepare in advance
Entry into forceCore measures on releasing AI products take effect on promulgation. Risk control, oversight and serious-incident provisions take effect 180 days after promulgationAbout six months to prepare after promulgation
Summarised from Tilleke & Gibbins and BDO, because the draft itself on the government's central law portal could not be opened when we checked · the draft can still change before it is promulgated

Sector regulators

The financial sector is the clearest. The BOT issued policy guidelines on risk management for the use of AI systems, dated 12 Sep 2025 (B.E. 2568). The document is policy guidance for financial institutions to refer to, not a notification with penalties of its own. But it is used alongside the IT risk requirements that are already binding. The capital markets and insurance sectors also have guidance from their own regulators. Organisations in regulated sectors must therefore read their regulator's documents alongside the PDPA, and should check the latest version directly with the regulator.

What organisations can do now

You do not need to wait for the AI law to be enacted. Most of the work the draft law would require is already recommended in the PDPC Office's guideline.

What to doWhich document it answers

Where you need an adviser

Whether your AI system counts as high risk or needs a licence under the draft law, questions of liability, and drafting contracts with providers are for your legal adviser to decide on the facts. This article helps you see the overall picture so you can ask the right questions. It is not a legal conclusion.

Frequently asked questions

Does Thailand have an AI law in force yet?
As of 18 Oct 2026, there is no AI-specific law in force. What already binds organisations is the PDPA and existing law such as consumer protection and civil liability. The Office of the Personal Data Protection Committee (PDPC Office) published the final version of its AI personal data protection guideline on 7 Oct 2026, and it was published in the Royal Gazette on 2 Nov 2026, but it has no legal force. As for the draft Artificial Intelligence Act, we have found no Cabinet resolution on it yet.Source: AI personal data protection guideline (in Thai) · PDPC OfficeSource: Thailand Releases New Draft AI Act · Tilleke & Gibbins
When will Thailand's draft AI Act take effect?
There is no fixed date yet. Public consultation on ETDA's draft closed on 14 Aug 2026, and as of 18 Oct 2026 we have found no Cabinet resolution. The draft must pass the Council of State, the Cabinet and Parliament before it is promulgated. Rajah & Tann estimates it will take 6–24 months to take effect, and the July 2026 draft has the risk-control provisions take effect 180 days after promulgation.Source: Thailand Moves Forward with Draft AI Act · BDOSource: Thailand's proposed AI law · Rajah & Tann
What duties and penalties does the draft AI Act set?
The July 2026 draft tiers AI by risk level. It bans AI that uses subliminal manipulation or discriminates on a wide scale. Organisations that deploy high-risk systems must have a risk management system and human oversight, and keep logs for at least 6 months. Foreign providers must appoint a representative in Thailand. The draft sets joint liability without proof of intent or negligence, and administrative fines of THB 1–5 million. It can still change before it is promulgated.Source: Thailand Releases New Draft AI Act · Tilleke & Gibbins
Is the PDPC Office's AI guideline legally binding?
No. Version 1.0, published on 7 Oct 2026, and the version published in the Royal Gazette on 2 Nov 2026 both state that it has no legal force and is not binding in the consideration of offences. But it was issued by the Personal Data Protection Committee under section 16(3) of the PDPA, so it is the regulator's own explanation of how the PDPA applies to AI work. For example, entering personal data into public AI is high risk.Source: AI personal data protection guideline (in Thai) · PDPC OfficeSource: PDPC Office AI guideline, Royal Gazette version (2 November 2026 (B.E. 2569)) (in Thai) · PDPC Office
What should organisations prepare before the AI law is enacted?
Make an inventory of where you use AI and rate the risk. Bar entering personal data into public AI, and use organisation accounts that have a data protection agreement. Put a ban on using your data to train models into your contracts. Have people review decisions that affect individuals. Keep logs of AI use in important work, and label AI-generated content that you publish externally. These tasks meet both the PDPC Office guideline and the draft Act.
What must financial institutions follow on AI use?
The Bank of Thailand (BOT) issued policy guidelines on risk management for the use of AI systems, dated 12 Sep 2025 (B.E. 2568), for the financial institutions and service providers it supervises to refer to. The document is policy guidance, not a notification with penalties of its own. But it is used alongside the IT risk requirements already in force, and the PDPA still applies in full.Source: BOT policy guidelines on risk in using AI systems (in Thai) · Bank of Thailand
