Where a foreign business licence for Bangkok is decided
A foreign business licence for a Bangkok company is not issued by an office in Bangkok. The Foreign Business Administration Division of the Department of Business Development (DBD) handles it from the 8th floor of the DBD building in Mueang Nonthaburi, according to the government's official service listing for licence applications.
The address matters less than it used to. Since August 2024 the DBD's e-Foreign Business system has covered the whole process online: submission, e-payment, digital signature and downloading the issued licence or certificate. In 2025 every applicant filed electronically, the DBD reports in its 2025 annual report on foreign business.
If you want to ask questions face to face, the Board of Investment's One Start One Stop Investment Center on the 7th floor of One Bangkok, on Rama IV Road, brings together 38 agencies, the DBD among them. It gives information and consultations on acquiring a foreign business licence. It does not decide applications.
Licence, BOI certificate or treaty certificate
The general rules, including which activities are restricted and how much capital is needed, are set out on our page on foreign business rules across Thailand. For a Bangkok company the practical question is which of three documents applies. In 2025 the DBD issued 291 licences, 663 certificates for promoted or industrial-estate businesses, and 124 treaty certificates.
- Foreign business licence (section 17). The DBD charges a 2,000 baht application fee. A List Three licence then costs 5 baht per 1,000 baht of registered capital, with a minimum of 20,000 baht and a maximum of 250,000 baht.
- Certificate for a BOI-promoted business (section 12). A company with investment promotion notifies the DBD for a certificate instead of applying for a licence. The DBD's service listing for this certificate says promoted companies file online through the BOI system, with a 15-day service standard and fees of 2,000 baht to apply and 20,000 baht for the certificate. Our guide to BOI promotion explains how promotion itself is obtained.
- Treaty certificate (section 11). Every treaty certificate issued in 2025 went to an American business under the Treaty of Amity, which our guide to the US Treaty of Amity covers.

How to compare the firms listed for this work
The firms on this page are law firms that handle foreign business licensing alongside company registration, BOI applications and tax. That combination is useful, because a licence application depends on how the company is set up and capitalised.
Each card shows the languages a firm works in, whether the first consultation is free and how long it lasts, and an hourly rate where the firm publishes one. Use the filters to narrow by language or consultation type. Before engaging a firm, ask:
- Who drafts the business description and answers the reviewing officer's questions?
- Is the fee fixed for the application, or hourly, and does it include company registration and bringing in the capital?
- What happens, and what does it cost, if the DBD asks for more documents?
- Which documents will be in Thai, and who arranges translation?
Business information to prepare for a foreign business licence in Bangkok
A first consultation is more useful when you bring facts rather than a general plan. The Foreign Business Act tells officials to weigh factors including the size of the undertaking, employment, technology transfer and research and development, so these points come up early:
- What the business will actually do. How it earns revenue, who its customers are, and where the Bangkok work happens. Classification turns on this.
- Shareholding. Who holds shares, their nationality, and any holding companies in the chain. A Thai company is foreign under the Act when half or more of its capital is held by foreigners, directly or through other companies.
- Capital. The planned registered and paid-up capital, and where the money comes from.
- Plans and projections. Expected spending, Thai staff numbers, and any training or technology transfer you intend.
- Thai partners. Any Thai shareholders, directors or joint-venture parties, and what each contributes.
- BOI or treaty status. Whether the business is promoted, applying for promotion, or US-owned.
- Directors. The Act requires an applicant to be at least 20, resident in Thailand or lawfully admitted, not bankrupt, and free of convictions under the Act in the past five years.
Local practicalities
Documents made or signed abroad need certification by an authorised officer or a Thai embassy or consulate no more than six months before filing. Foreign-language documents need a Thai translation signed on every page by the applicant and the translator, according to the DBD's conditions for licence applications.
The DBD's checklist provides for a power of attorney and the ID documents of both parties, so a firm can file on the company's behalf. Once granted, the licence or certificate must be displayed at the Bangkok place of business, and a move to new premises or closure must be notified within 15 days.

Common questions
Frequently asked questions
- Does a Bangkok company have to visit the DBD office to apply for a foreign business licence?
- Usually not. Since August 2024 the Department of Business Development's e-Foreign Business system has handled submission, payment, digital signature and download of the licence online, and in 2025 every applicant filed electronically. The division that reviews applications is at the DBD building in Mueang Nonthaburi. Questions from the reviewing officer still need someone who knows the business well enough to answer them.
- Can a law firm file a foreign business licence application on a company's behalf?
- Yes. The Department of Business Development's document checklist provides for a power of attorney together with ID documents for the person granting it and the person receiving it, so an authorised representative such as a law firm can file. The company still supplies the facts and documents behind the application, and a Thai translation is needed for anything in a foreign language.
- What documents does the DBD ask for with a foreign business licence application?
- The published checklist includes the application form, a statement describing the business in detail, a map of the place of business, a declaration that directors or managers meet the Foreign Business Act's qualifications, and power of attorney and ID documents where a representative files. Documents made abroad need certification within six months before filing, and foreign-language documents need a Thai translation signed on every page.
- Does a US-owned company in Bangkok need a foreign business licence?
- A qualifying American-owned business can apply for a foreign business certificate under section 11 of the Foreign Business Act, relying on the Treaty of Amity, rather than a licence. In 2025 the DBD issued 124 such certificates, all to American businesses. The treaty has its own limits, so a lawyer can check whether the intended activity is covered.
- What does a Bangkok company have to do after a foreign business licence is granted?
- Under the Foreign Business Act the licence or certificate must be displayed openly at the place of business, and the company must notify the registrar within 15 days if it moves its office or stops the licensed business. The licence covers the activities it describes, so a change in what the business does can also need attention.
