Company registration

Register a Thai Company Yourself or Use a Service?

Published 9 Aug 2026

What DIY registration involves

The filing is more than entering names into a form. The incorporation package must consistently reflect the company name, activities, shareholders, capital, directors, signing authority and registered address.

  • Confirm that the proposed activities fit the ownership structure
  • Prepare the memorandum and required registration forms
  • Coordinate the founder, shareholder and director information
  • Prepare and collect the required signatures and supporting documents
  • Submit the package and respond if clarification is requested
  • Identify any tax, employment, licence or foreign-business work needed afterwards

When DIY may be suitable

DIY may be reasonable when the structure is straightforward, the founders understand the Thai filing requirements, the documents are readily available and there is no uncertainty about foreign ownership or restricted activities.

What a registration service should add

A useful service should do more than submit forms. It should organise the founder's decisions, identify missing information, prepare a consistent package, coordinate signatures and explain what is included or excluded from the scope.

Corporly's standard incorporation scope covers the initial setup review, preparation of incorporation documents, signature coordination and filing support. Tax, VAT, Social Security, foreign-business, BOI and sector-specific work are separate unless expressly included.

When using a service may be more practical

  • Foreign ownership or a foreign corporate shareholder is involved
  • The business activity may be restricted or separately licensed
  • Foreign documents may need translation or authentication
  • The founders are uncertain about capital, directors or signing authority
  • The registration must connect with a wider operating plan
  • The founders want one organised process and a clear scope

The practical comparison

DIY can reduce professional fees when the structure and filing are genuinely simple. A registration service becomes valuable when it reduces founder time, prevents inconsistent documents and connects the filing with the business the company must actually operate.

No service can guarantee registration or an authority's decision. The value is in preparation, consistency, scope control and follow-through.

This article provides general information. The appropriate approach depends on the proposed ownership, activities, documents and operating plan.
