Online filing becomes mandatory for new company registrations in Thailand.

Thailand’s Department of Business Development (DBD) has moved new private limited company and partnership registrations fully online through its Biz Regist platform. From 1 July 2026, walk-in applications for these incorporation services are no longer accepted, making digital submission the only route for registering a new company in Thailand.

The shift follows a period of rising online adoption, with the DBD reporting that the majority of new registrations were already being filed through Biz Regist ahead of the formal cutover. For businesses planning to establish a presence in Thailand, understanding how the new process works and what it means for incorporation timelines is an important first step.

The Biz Regist filing requirement

Promoters now submit all incorporation documents through the online portal, including:

• The memorandum of association
• The list of shareholders
• Director details and identification documents

While the filing channel has changed, the substantive legal requirements for incorporation remain the same. Shareholder documentation, director information, company structure and foreign ownership restrictions under the Foreign Business Act continue to apply exactly as before. Biz Regist is a procedural shift in how applications are submitted and processed, not a relaxation of Thailand’s underlying company law.

Other corporate filings unrelated to new company formation, such as changes of director, registered address or capital increases, remain unaffected for now and can still be filed on paper where applicable.

Practical considerations for foreign investors

The move to a fully digital system has particular implications where overseas directors or shareholders are involved. Companies incorporating with a mix of local and foreign shareholders should consider the following:

• Identity verification and electronic signatures are typically completed through the DBD’s e-Service system or ThaID, which can take longer to arrange for individuals signing from outside Thailand.
• Documents may still need to be notarised or legalised before submission, depending on the signatory’s location.
• Building extra time into the registration timeline is advisable, particularly where multiple overseas signatories are involved.

Engaging a local adviser familiar with the Biz Regist workflow can help avoid delays caused by formatting or verification issues that would previously have been resolved in person at a DBD counter.

What this means for incorporation planning

The transition to fully online incorporation reflects Thailand’s broader move towards digitalising business registration and aligns with similar reforms across other government services. For most domestic promoters, the change is likely to streamline what was previously a paper-based process, reducing the need for in-person visits to the DBD.

For foreign investors, the change places greater weight on preparing documentation correctly and in advance. This is a shift in emphasis rather than a new burden: the underlying incorporation requirements remain unchanged, but the process now rewards early preparation over the ability to resolve issues in person on the day.
