BOI Promotion Application Thailand

The Board of Investment grants promotion under the Investment Promotion Act B.E. 2520 by reference to its published activity list. Each activity carries its own conditions and benefit set. We map the project to an activity, prepare the application and the certified foreign documents, and support the officer's presentation stage.

Governing authority / legal basis: Investment Promotion Act B.E. 2520 (1977), as amended; administered by the Office of the Board of Investment
Turnaround: Preparing the project rationale and the investor's certified documents usually takes 2–4 weeks. The Board's own consideration follows its published stages and the size of the project; treat any date as an estimate and check the Board's current notice.
Fees: Quoted per matter once we see the shareholding, the activity and the documents already on file. Government and registrar fees are charged at the authority's own rate and are separate. Confirm scope and fees with our staff by phone, Line or Email before any filing is prepared.

What we handle

Activity mapping

Matching the project to an activity on the Board's published list, and identifying the conditions attached to that activity before the application is drafted.

Project rationale

Investment plan, capital structure, technology or value-added rationale, and employment plan, written in the terms the Board's officers assess.

Investor documents

Overseas corporate documents, notarised and legalised for use in Thailand, with certified Thai translations.

Post-approval conditions

A calendar of the reporting and compliance obligations attached to the promotion, so the benefit is not lost through a missed condition.

Documents required

Document	Issued / prepared by	Watch out for
Project description	Client	Product or service, process, and where each stage is performed. This determines the activity code.
Investment and capital plan	Client	Registered capital, funding source and the investment schedule.
Investor corporate documents	Overseas registry	Certificate of incorporation, financial statements and board resolution, legalised and translated.
Employment plan	Client	Thai and foreign headcount, and the skilled positions the project needs.
Machinery or technology list	Client	Where the activity turns on production or technology, the list supports the activity classification.

Document lists, official fees and acceptance conditions vary between offices, branches and provinces, and change by notification. Confirm with the receiving authority before you act on this page.

How the process runs

1
Eligibility review
We check whether the project matches an activity on the current list and which conditions come with it.
2
Application drafting
The application and project rationale are prepared and filed through the Board's system.
3
Officer presentation
The project is presented to the responsible officer. Questions usually target the value-added rationale and the employment plan; we prepare answers from the filed document set.
4
Certificate and conditions
On approval, the promotion certificate is accepted within the stated period and the compliance calendar starts.

Why files get rejected

Promotion is granted by activity. A company can hold promotion for one activity and be unpromoted for another; the accounting must keep them apart.
Benefit sets differ by activity and by the Board's current announcements. We do not quote a benefit until the activity is fixed, because the wrong figure at the planning stage is worse than none.
A promoted project carries conditions — capital, timing, reporting. Losing a benefit for a missed condition is more common than a refusal at the application stage.
BOI promotion can support work permit and visa facilitation for the project's foreign staff, but each of those remains a separate application under its own authority.
Approval is at the Board's discretion. No adviser can guarantee promotion or a particular benefit level.

Frequently asked questions

คำถามที่พบบ่อย (FAQ)

Which businesses qualify for BOI promotion?+

Only activities on the Board's published activity list, and only where the project meets that activity's conditions. The list is revised over time, so the current announcement governs — an activity that qualified for a colleague's project two years ago may sit under different conditions today.

Does BOI promotion allow full foreign ownership?+

Promotion can permit foreign majority in activities that would otherwise be restricted, and it is one of the recognised routes alongside a Foreign Business Licence and Treaty of Amity certification. The permission attaches to the promoted activity, not to the company at large.

How long does the application take?+

It depends on project size and the Board's queue. Realistically the certified overseas documents, not the review, set the earliest possible filing date.

Can an existing company apply?+

Yes. An operating company can seek promotion for a new qualifying activity or an expansion, provided the promoted activity is separable in the accounts from the unpromoted business.

What happens after approval?+

The certificate must be accepted within the period stated, and the conditions begin. Reporting obligations continue for the life of the promotion, which is why we hand over a compliance calendar rather than just the certificate.

Deep Context and Service Standards

Sourced from the Lawyer Act B.E. 2528 (1985), the Lawyers Council Regulation on Notarial Services Attorneys B.E. 2546 (2003), the Personal Data Protection Act B.E. 2562 (2019), the Hague Apostille Convention of 1961, and official publications of the Department of Consular Affairs (MFA).

Firm Overview and Practice Framework

Thai Notary Service is a full-service Thai law office providing document notarization, certified translation, legalization chain management, and international document consultancy. Our team includes Notarial Services Attorneys licensed by the Lawyers Council of Thailand under the Royal Patronage, and we operate offices in Bangkok, Greater Bangkok, and a partner network in every province across Thailand. We serve individuals, expatriates, cross-border couples, students, corporates, multinationals, and government agencies requiring documents with legal effect both inside Thailand and abroad.

All notarial acts follow the Lawyer Act B.E. 2528 (1985) Section 27 read with the Lawyers Council Regulation on Notarial Services Attorneys B.E. 2546 (2003), the sole legal basis authorizing Thai attorneys to certify documents comparable to a foreign Notary Public. Every attorney on our team has completed the accredited training and examination administered by the Lawyers Council and holds a verifiable registration number searchable on the Lawyers Council public registry.

By choosing a firm that houses Notarial Services Attorneys in-house, clients consolidate a multi-stage legalization chain under one accountable roof: attorney notarization, followed by Ministry of Foreign Affairs (MFA) legalization at the Department of Consular Affairs, followed by embassy or consular legalization for the destination country. Since 21 November 2024 the Kingdom of Thailand has become a party to the Hague Apostille Convention (Convention of 5 October 1961 Abolishing the Requirement of Legalisation for Foreign Public Documents). Documents apostilled in Thailand are now accepted in more than 125 member states without embassy re-legalization, materially reducing turnaround time and cost.

General Information and Firm Framework — Deep Context

The firm operates under an ISO 9001:2015 quality-management framework and enforces data protection consistent with the Personal Data Protection Act B.E. 2562 (2019). All client documents are stored with AES-256 encryption at rest and in transit and are retained for ten years in accordance with lawyer-record obligations under the Lawyer Act.

Our team combines Notarial Services Attorneys, NAATI-certified translators, and legal specialists in intellectual property, taxation, cross-border family law, corporate law, and immigration law, together with a support team dedicated to documentation, translation, and government-agency liaison.

Fees are transparent and disclosed both on the website and in the pre-engagement quote, separating professional fees, government fees, travel disbursements (if any), and other line items. The firm issues VAT invoices and official receipts and accepts payment by bank transfer, credit card, PromptPay, and cash.

Trust Standards — PDPA, SLA, Quality Assurance

On data protection, the firm strictly follows the Personal Data Protection Act B.E. 2562 (2019), Sections 24, 26, and 27 — collecting, using, and disclosing personal data only to the extent necessary for the engagement, disclosing purposes, and obtaining consent from data subjects in advance. Clients retain the right to inspect, obtain a copy, rectify, erase, or withdraw consent at any time through the firm's Data Protection Officer (DPO). For clients in the European Union, processing follows GDPR Article 6 (lawful basis) and Article 46 (Standard Contractual Clauses).

Our Service Level Agreement targets an inquiry response within one hour during business hours (09:00–18:00, Monday to Saturday), attorney appointments within twenty-four hours, standard notarization within one business day (or two to three hours on express service), certified translation within three to five business days per ten A4 pages, MFA legalization within two business days on standard service (one business day express), and embassy legalization typically within three to fifteen business days depending on the mission's own policy.

Every deliverable passes a three-tier quality-assurance chain: (1) the responsible attorney or translator, (2) a Senior Attorney or department head reviewing substance and formatting, (3) a Quality Control desk performing the final pre-delivery check. Any firm-side error is remedied at no additional cost, and if a document is rejected by a government authority due to a firm-side error, we cover the entire re-filing fee.

Contact and Initial Consultation

Initial consultation is complimentary via Line @thainotary or by phone at 094-8958999. The team responds within one hour during business hours. Every inquiry is treated confidentially under the Lawyers Council ethics rules and the Personal Data Protection Act.
