On July 8, 2026, Thailand enacted a new law significantly expanding the framework for government service delivery and licensing facilitation. The Facilitation of Licensing and Public Services Consideration Act B.E. 2569 (2026) (Facilitation Act 2026) replaces and expands the framework of governmental services under the Facilitation of Official Licensing Consideration Act B.E. 2558 (2015) (Facilitation Act 2015) and broadens its scope to cover public services, administrative processes, and public benefits. The Facilitation Act 2026 aims to modernize government services by promoting e-filing, reducing administrative burdens and repeated document requests, and improving predictability. For businesses, this should ease compliance and shorten approval timelines, subject to implementing regulations and agency readiness. Public Services Facilitation Scope The Facilitation Act 2015 applied mainly to permissions, registrations, and notifications required before conducting activities that require licenses, certificates, permits, approvals, or registrations. The Facilitation Act 2026 broadens this framework to include public services and other benefits, such as welfare, subsidies, and grants, provided to Thai citizens, expanding government agencies’ responsibilities beyond licensing facilitation into a wider administrative-service framework. It also introduces a broader definition of “government agency” to include central, regional, and local government bodies, state enterprises, public organizations, and other state entities. Licensing Changes The Facilitation Act 2026 introduces a “super license” (termed a “main license” under the act) that exempts the holder from obtaining multiple related or ancillary licenses issued by different government agencies. Obtaining a super license deems the licensee to have automatically obtained the related “sublicenses” required to conduct the relevant activities. The cabinet will designate eligible activities by royal decree. The act also introduces an expedited licensing option, allowing applicants to pay an additional fee to fast-track their applications in urgent cases. Expedited processing must not interfere with standard application timelines. The criteria, procedures, conditions, and fees for expedited licensing
