Thailand BOI Applications and Project Compliance

1. What product or service the project will deliver, to whom, and how revenue is earned.
2. Which production or service activities will actually be performed in Thailand.
3. The current project stage, including any earlier application or clarification record.
4. The proposed investment, principal equipment or systems, funding, location and implementation timetable.
5. The proposed management, technical and staffing arrangements.
6. Any location, utility, environmental, safety, product-licensing, machinery or raw-material issues that may require separate review.

Supporting materials may include product or service information, process or service-flow documents, principal machinery or system details, implementation and staffing plans, corporate records, recent financial statements if available, and relevant authorisation documents. A project-specific list should be confirmed after the proposed activity and promotion category have been reviewed.

Chinese investors planning computing-equipment rental, server hosting or related services in Thailand can supplement their existing project materials with the following links between facts and documents. This helps identify gaps at the first consultation. It is a consultation-preparation checklist, not a universal government filing list. Refer to pages in existing documents rather than preparing another report.

1. Business model: Separate equipment rental, colocation, operations and maintenance, cloud-platform and resale services. Explain what the customer receives and what the Thai company delivers. Provide a one-page service flow identifying steps performed by overseas affiliates or third parties. Do not assume a commercial label determines the BOI category.

2. Revenue and contracts: For each revenue stream, select a redacted quotation, order or contract sample. Identify the contracting party, payer, payment recipient, billing unit and delivery responsibilities. If rental, hosting, maintenance or resale charges are bundled, explain the basis for separating them. Label unsigned documents as drafts.

3. Ownership and control: Map direct and indirect shareholdings between investors and the Thai operating entity. Separately identify who controls director signatures, pricing, customer contracting, equipment allocation and technical operations. Distinguish corporate control from day-to-day operating authority. Entity codes are sufficient initially; account or system login details are not needed.

4. Equipment and locations: For each site, identify the data-center operator, equipment owner, lessee, import arrangements and actual installation location. Link equipment entries to purchase, lease or data-center service documents. State models, quantities, budgets and delivery stages. For relevant certifications, capacity or power information, identify the issuer, covered location and date rather than relying solely on a group brochure.

5. Evidence and gaps: For each fact, record the source document, page, version, person responsible for confirmation and status: confirmed, estimated or under negotiation. Where contracts, budgets, equipment schedules or flow diagrams conflict, list the discrepancy and question to resolve. Do not make premature commitments simply to complete the materials.

Start with this cross-reference list and redacted samples, then confirm which originals or specialist materials are needed. Within the agreed scope, THAIHOUSING can help check consistency between the project description and supporting materials and identify BOI-category and FBL/FBC questions for separate assessment. The appropriate route remains subject to the actual business and applicable requirements.

For an application under activity 8.2.4.1, a feasibility study is required. The activity-specific conditions require capital investment of at least THB 5 billion, excluding land cost and working capital. BOI’s general rules require a feasibility study for investment exceeding THB 2 billion on the same basis. Applying these rules together, a project meeting the minimum investment condition for activity 8.2.4.1 exceeds the feasibility-study threshold.

A plan outlining activities that contribute benefits to Thailand is also expressly required under activity 8.2.4.1. The project must fully implement the proposed plan before exercising the corporate income tax exemption incentive. Examples in the official conditions include training, curriculum development or joint research with educational institutions, skills development for Thai SME entrepreneurs, and support for the domestic supply chain. The applicable document title, template and submission method should be confirmed; this does not make the plan optional.

Whether a separately titled Business Plan must be filed should be checked against the applicable application form and project-specific requirements. The business facts should nevertheless be prepared, including customers, revenue model, activities in Thailand, investment, equipment or systems, staffing and implementation plans. These facts support the application and feasibility analysis; they do not remove the express requirements for a feasibility study and a Thailand-benefit activities plan.

THAIHOUSING may collect the common project facts once and map them into the required application, feasibility, business and Thailand-benefit materials. Repeated facts can be reused, while document-specific analysis, calculations and commitments remain separate and must be confirmed by the applicant.

Preliminary assessment, application preparation and filing, project clarification, resolution acceptance, promotion-certificate work and post-approval compliance are not automatically one unlimited engagement. The agreed quotation or engagement document should identify the included stages, deliverables and fees. Government charges and third-party translation, notarisation, technical, environmental, engineering, accounting, tax or testing work are excluded unless expressly included.

BOI promotion and foreign-business licensing address different questions. Company registration or BOI approval does not by itself complete every foreign-business, product, construction, environmental, tax, visa or other regulatory requirement. Any separate work should be identified against the project’s actual activities.
