- Signed term sheet / LOI
- DD report feeding the disclosure schedule
- Latest DBD affidavit and BorJor.5

Common Pitfalls

Typical Use-cases

FAQ
- Do we file with DBD?
- Private-company share transfers don't require immediate DBD filing; BorJor.5 is updated at the next AGM.
- What does the MAC clause protect?
- It lets the buyer walk away if a materially adverse event hits the target between signing and closing.
- Who pays stamp duty?
- Customarily the transferor, but the SPA can shift it to the buyer.

Frequently asked questions
- Can a foreigner own 100% of a Thai company?
- Generally no for activities listed in the Foreign Business Act, where majority foreign ownership requires a Foreign Business Licence, a BOI promotion, or treaty rights such as the US–Thailand Treaty of Amity. Manufacturing and certain export activities are largely open, and BOI-promoted activities can permit full foreign ownership together with land-holding and visa privileges, so the right structure depends on the specific activity.
- What is the minimum registered capital for a Thai company?
- There is no general statutory minimum for a Thai-majority company, but practical thresholds apply: THB 2 million of paid-up registered capital per foreign work permit, or THB 1 million if the foreigner is married to a Thai national, and THB 3 million per foreign shareholder for a Foreign Business Licence. Capital should therefore be planned around the visa and work-permit outcome you need, not the incorporation minimum.
- How long does company registration take?
- Registration at the Department of Business Development can be completed within one to three working days once the name reservation, shareholder documents and company objectives are ready, and the VAT registration and social security registration follow afterwards. The realistic end-to-end timeline including bank account opening is two to six weeks, with the bank account usually being the slowest step for foreign directors.
- What ongoing accounting obligations does a Thai company have?
- Every Thai company must keep statutory accounts, file monthly withholding tax (PND 1, 3, 53) and VAT (PP 30) returns by the middle of the following month, file the half-year corporate income tax return (PND 51) and the annual return (PND 50), and have its financial statements audited by a Thai CPA and filed with the DBD each year. Dormant companies are not exempt — nil returns and an audited statement are still required.
