Joint Ventures Between Thai and Foreign Partners
Joint ventures are common for project bids, construction and Thai-foreign investment. Decide early whether you will cooperate by contract or form a new company, because tax and liability differ sharply.

Is a joint venture taxed separately in Thailand?
Yes. The Revenue Code treats a joint venture as its own corporate income tax unit, so it needs its own tax ID and may need separate VAT registration.

Frequently asked questions
Must a joint venture register with DBD?+
A contractual one is not a legal entity, but it must get a tax ID from the Revenue Department. An incorporated one registers as a company.
How much can a foreigner hold?+
Below half, the company is generally not foreign. At half or above, check whether the business is on a restricted list.
Can a joint venture bid for government work?+
Many tenders allow it, but conditions are set in each tender document. Check before signing.

Frequently asked questions
- What makes a Thai translation 'certified' and who is allowed to certify it?
- A certified translation is a translation issued with a signed certification statement from a translation agency or qualified translator confirming the text is a true and complete rendering of the original. Thailand has no single government translator register for general use, so acceptance depends on the receiving authority: the Department of Consular Affairs accepts translations submitted with the original document for legalization, embassies usually accept agency-certified translations, and some foreign authorities additionally require a sworn or NAATI translator. We confirm the receiving body's rule before translating so the document is not rejected later.
- Do I need the original document or is a scan enough for translation?
- A clear scan is enough to produce the translation, but the original is normally required for the legalization step that follows. The Department of Consular Affairs checks the translation against the original or a certified true copy issued by the responsible Thai authority, so if you plan to legalize, send us a high-resolution scan to start the translation and keep the original ready for submission.
- How should Thai names be spelled in an English translation?
- Always match the spelling printed in the passport, even when it differs from Royal Thai General System transliteration. Authorities compare the translation against the passport and treat any mismatch as a different person, which is one of the most common causes of rejection. If a name has been spelled differently on older documents, we add a spelling-variation note or arrange a name-consistency affidavit.
- How long does a certified translation take and can it be rushed?
- Standard civil documents such as an ID card, house registration, birth or marriage certificate are typically ready in one to two working days, while contracts, court judgments and academic transcripts take longer because of terminology checks. Same-day handling is possible for short standard documents if the scan arrives in the morning; rush handling does not shorten the separate MFA legalization queue.
We advise first, then do the work
Before translating we confirm which form the receiving authority actually accepts — agency certification, MFA legalisation, or a translator declaration before an attorney.
- Free case assessment before you commit — send photos of your documents and we tell you what is actually needed.
- A team of licensed attorneys, notarial services attorneys and registered translators, with since 2019 of combined practice.
- We flag risks and alternatives in writing — including when the cheaper or faster route is the correct one.
- We stay with the case after delivery: if the receiving authority asks for more, we advise at no extra consulting fee.
