Thailand Proposes Significant Amendments to the Personal Data Protection Act

Subscribe to Updates

Thailand’s Personal Data Protection Act B.E. 2562 (2019) (PDPA) could soon see some important changes, as a draft bill to amend the PDPA has been introduced in the House of Representatives. The draft amendment is currently in the public consultation phase, with comments accepted from July 16 to August 15, 2026. If enacted in its current form, the amendment would make three key changes: expanding the government exemption to cover anticorruption operations, introducing a statutory definition of “government agency,” and restructuring the lawful bases for personal data processing to align with international standards.

Background

The PDPA has encountered several enforcement challenges since its implementation, including three core problems identified by the bill’s sponsors: (1) the current exemptions for government agencies do not cover anticorruption and misconduct-prevention operations; (2) the PDPA lacks a clear statutory definition of “government agency,” causing legal uncertainty as to which entities are covered; and (3) the existing framework for lawful bases of data processing does not align with international standards—particularly the multiple-lawful-bases system in the EU’s General Data Protection Regulation (GDPR)—making compliance inflexible for both government and private sector entities.

Expanded Government Exemption

The current PDPA exempts government agencies performing duties related to national security (including fiscal security), public safety, anti-money laundering, forensic science, and cybersecurity. The proposed amendment adds “prevention and suppression of corruption and misconduct” to this list of exempted functions. This would allow anticorruption bodies—most notably the National Anti-Corruption Commission (NACC), which is identified as a directly affected party—to collect, use, and disclose personal data without being subject to PDPA requirements when carrying out their duties.

New Statutory Definition of “Government Agency”

Notably, while the current PDPA use the term “government agency” in several provisions, the term is not comprehensively defined, creating potential uncertainty as to its scope. The draft bill therefore inserts a new definition of “government agency” to cover central government agencies, regional government agencies, local government agencies, state enterprises, public organizations, Parliament, courts, independent constitutional organizations, the Office of the Attorney General, public higher-education institutions, and independent state agencies. The proposed definition seeks to clarify which entities are considered “government agencies” and covered by the act.

Restructured Lawful Bases for Data Processing

The most significant proposed change for both government and private-sector organizations is the restructuring of the PDPA’s section 24, which currently prohibits data controllers from collecting personal data without consent, subject to certain exceptions framed as carveouts.

The proposed amendment would restructure section 24 to adopt a multiple-lawful-bases model aligned with the GDPR, and add more clarity on the public-task basis. Under the new framework, personal data processing would be lawful when carried out under at least one of the following bases:

  • Archival/research/statistical: For historical or archival purposes in the public interest, or for research or statistics with appropriate safeguards, as prescribed by the PDPC board.
  • Public task/official authority: Necessary for performing a public-interest mission or exercising official authority, including government disclosure obligations under the Official Information Act or other laws.
  • Vital interests: To prevent or suppress danger to a person’s life, body, or health.
  • Contractual necessity: Necessary for performing a contract with the data subject or for pre-contractual steps at the data subject’s request.
  • Legitimate interests: Necessary for the legitimate interests of the data controller or a third party, unless overridden by the data subject’s fundamental rights.
  • Legal obligation: Necessary for compliance with a legal obligation of the data controller
  • Consent: The data subject has given consent.

The most critical structural shift is that consent is repositioned from the default requirement to one of seven coequal lawful bases.

Next Steps

All organizations should monitor the public consultation process, which is open until August 15, 2026. If enacted, the bill will take effect the day after its publication in the Government Gazette.

The Personal Data Protection Committee (PDPC) of Thailand’s Ministry of Digital Economy and Society (MDES) has announced the first administrative fine under the Personal Data Protection Act B.E. 2562 (2019) (PDPA). A major private company was fined THB 7 million for noncompliance with specific PDPA requirements, resulting in the unauthorized disclosure of personal data to a call center gang (phone scam fraudsters). Key Findings of Noncompliance The PDPC determined that there were three key violations of specific requirements of the PDPA: Failure to appoint a data protection officer (DPO): Despite processing personal data for over 100,000 individuals as part of its core operations, the company did not appoint a DPO. Inadequate security measures: The company lacked the required security measures, leading to a data breach involving a call center gang, causing widespread damage. Delayed data breach notification: The company did not notify authorities of the data breach within the required timeframe and failed to address the breach promptly, making it impossible to remedy the situation. In addition to the monetary fine, the PDPC, along with the PDPA’s Expert Committee, issued a corrective order requiring the company to undertake the following actions and notify the Office of the PDPC of the relevant correction measures within seven days of receiving the order: Implement up-to-date security measures: The company must improve its current security measures to prevent future breaches and ensure that the security measures are up-to-date with changing technologies. Raise awareness of personnel: The company must provide training to relevant personnel to ensure awareness of data compliance and protection practices. This significant administrative action establishes a precedent for addressing data breaches in both governmental and commercial sectors in Thailand. It also confirms the importance of PDPA compliance, particularly the need for robust security measures, timely breach notifications, and the appointment of

On August 9, 2024, Thailand’s Electronic Transactions Development Agency (ETDA) opened a period for public feedback regarding the 2022 Royal Decree on Digital Platforms and its subregulations. To collect this feedback, the ETDA has prepared a 44-question survey on specific attributes of the royal decree and its requirements, covering issues such as the definition of digital platform services (DPSs), types of services that are subject to notification requirements, information that must be submitted annually, and the royal decree’s extraterritorial scope. Business operators that fall within the scope of the royal decree and wish to provide feedback on its effectiveness should prepare and submit the survey online to the ETDA by the end of August 2024. Royal Decree on Digital Platforms Thailand’s Royal Decree on Digital Platforms was published in the Government Gazette on December 22, 2022. It defines a DPS as any service that facilitates or mediates transactions between users through a digital platform, such as e-commerce, food delivery, ride-hailing, online travel agency, online payment provider, or social media platform. The decree requires DPS operators to notify the ETDA before commencing operations, with some limited exemptions. The decree also empowers the ETDA to issue notifications (i.e., subregulations) and guidelines for implementing the decree and to monitor and enforce compliance by DPS operators. The ETDA may impose administrative sanctions, such as warnings, fines, service suspension, or revocation of notification, for any violation of the royal decree or the ETDA’s subregulations. In-scope DPS operators should take this opportunity to provide comments to the ETDA in order to voice their opinions on the practicality of the requirements and support the regulator in shaping the requirements of the royal decree and its subregulations.
