Can Americans own 100 percent of a Thai company?

Answered by the corporate team at NYC Visa & Translation

In most sectors yes, under the Treaty of Amity and Economic Relations between Thailand and the United States of 1966, certified by the Department of Business Development on the strength of a nationality certification from the US Embassy. The treaty still reserves communications, transport, fiduciary functions, banking involving depository functions, exploitation of land or other natural resources, and domestic trade in indigenous agricultural products. Amity status does not by itself grant a work permit or land ownership, and it lapses if the American shareholding falls below the required level. Ask our Thai corporate team to review your structure by phone, LINE or email before you file.

Based on the Civil and Commercial Code, the Foreign Business Act B.E. 2542, the Investment Promotion Act B.E. 2520 and related legislation as at August 2026. General information only, not advice on a specific matter — verify with dbd.go.th and boi.go.th before acting.
