Board of Investment (BOI) Promotion — 2025 Strategy

BOI promotion is Thailand's flagship investment-incentive regime, offering 3–13 years of corporate income tax exemption, import duty relief, 100% foreign ownership, land-ownership rights, and OSOS work-permit fast-tracking. The 2023–2027 strategy prioritises seven target industries: Bio-Circular-Green (BCG), Digital, Advanced Manufacturing, Creative Industries, Vehicles of the Future, Medical & Wellness, and Defence. iLC prepares BOI Category 5 (Digital) and Category 7 (High-Value Services) applications end-to-end, including feasibility, capital plan, technology transfer scoring, and personal-income-tax reduction filings.

Documents usually required

  • Freshly issued company affidavit and certificate of registration
  • Memorandum and articles of association, or the current shareholder list
  • Board resolution or power of attorney signed by the authorised director
  • ID or passport copies of the authorised signatories

Common reasons a bundle is rejected

  • Company affidavits are usually accepted only within a short validity window.
  • Director names and job titles must match the registered filing exactly.
  • Spell every name exactly as it appears in the passport, across every document in the same bundle.

Prefer not to handle the chain yourself? Send the scans and we run every step for you, from translation to the final endorsement.

How the process runs — Corporate and company document certification

  1. Obtain freshly issued corporate records covering the whole group of entities involved.
  2. Prepare the board resolution or power of attorney signed by the authorised director.
  3. Translate using the registered English company name and the job titles exactly as filed.
  4. Complete the certification route the counterparty or destination authority requires.
  5. Deliver the certified set together with copies for internal corporate records.

Fees and processing times are set by each authority and vary by document and destination — confirm them with the responsible agency.

Handling it yourself vs letting iLC run it

AspectDoing it yourselfWith iLC
Working out which steps applyYou read each authority's rules yourself, and usually learn a step was missing only after the bundle is refused.Our advisers review the documents before work starts and sequence translation, notarisation, MFA, and embassy in one pass.
Time spent filingRepeat trips to each office, queueing and collecting in person.We file on your behalf; you send scans and receive the finished set by post or courier.
Risk that the translation is refusedAgency names, job titles, and the certification wording often do not match what the receiving office accepts.We use terminology and certificate formats the receiving authority has accepted before, with two-stage proof-reading.
If the bundle is rejectedYou diagnose the cause and refile yourself, losing a full cycle.We identify the cause, correct it, and refile without you starting over, with progress reported along the way.

What clients typically use this for

  • Foreign subsidiary registration
  • Bank account opening abroad
  • Tender and contract submissions

An advisor, not only a document processor

Before any work starts, our team assesses how many certification layers your document actually needs, which authorities are involved, and the correct order for the office you will really file with. One step out of order usually means restarting the whole bundle. More than 15 years of cross-border document work means we recognise how each authority rejects files and prevent it up front.

  • The certification route is matched to the receiving authority before work begins.
  • Rejection risks are checked, from name spelling to document validity windows.
  • The filing sequence is planned around the deadline you actually have.
