It is recommended to complete “BOI eligibility and category assessment” prior to company registration, and advance company‑incorporation procedures in parallel with BOI document preparation. Where conditions permit, Zhongxin Tax & Accounting prefers submitting the formal BOI application under the newly‑established Thai corporate entity after company registration. This keeps equity structure, registered capital, business scope, factory site location and BOI project requirements aligned from the outset, eliminating extra coordination work required for converting an individual‑led application into a corporate‑entity submission at a later stage.
1. Legally You “May Apply First and Register the Company Later”, Though It May Not Be Time‑Efficient in Practice
Official BOI FAQs explicitly state that natural persons are permitted to submit investment‑promotion applications and receive BOI resolutions. However, when the formal investment‑promotion certificate is issued, the applicant must already be registered as a Thai‑legal entity such as a limited‑liability company, cooperative or foundation. Accordingly, “you must register a company before submitting a BOI application” is not a statutory mandatory requirement.
Nevertheless, Zhongxin’s practical guidance is as follows: if the client has confirmed investment into Thailand and company registration itself requires only a short preparation cycle, prioritize parallel workflows for company incorporation and BOI pre‑assessment. File the formal application under the final operating legal entity once the company is registered. This facilitates unified downstream administration of capital contributions, equipment imports, invoicing, banking facilities and certificate‑related obligations.
2. Reasonable Timeline for Launching a BOI Application
| Phase | Company Workstream | BOI Workstream | Key Objective |
|---|
| After project approval | Confirm equity, capital, registered address, directors and business scope. | Conduct preliminary assessment covering eligible activity categories, qualification criteria, investment value, manufacturing processes and equipment lists. | Avoid discovering BOI‑condition mismatches after company registration is completed. |
| Phase 1 | Proceed with DBD company‑registration formalities. | Prepare supporting documentation including project narratives, manufacturing workflows, equipment specifications and investment plans. | Execute both workstreams concurrently. |
| Post‑company‑incorporation | Advance post‑licence registrations such as corporate banking and VAT according to schedule. | Submit or take‑over the BOI application in the name of the corporate entity. | Maintain consistency between the legal entity and project‑specific BOI conditions. |
| BOI review period | The company undertakes business activities that do not depend on BOI incentives, within the scope of its statutory registered‑business authority. | Attend interviews, respond to document‑supplement requests, receive formal resolutions and apply for the investment‑promotion certificate. | Do not claim BOI incentives prior to obtaining formal BOI entitlements. |
3. Expected BOI Lead Time: Distinguish “Official Review Period” vs. Full‑Project Timeline
According to official BOI FAQs, project review durations range from approximately 40‑90 working‑days depending upon project category and investment scale. However, the full end‑to‑end cycle includes document drafting, project narratives, interviews, supplementary‑submission rounds, resolution acceptance, company‑incorporation / capital‑contribution arrangements and final certificate issuance. For manufacturing‑sector projects, Zhongxin schedules backwards against a more complete real‑world timeline. Where communicating a 6‑8‑month overall timeline to clients, it must be clarified that this reflects Zhongxin’s full‑project scheduling estimate and is not the statutory official BOI review deadline.
4. Application of Zhongxin’s CODE Compliance‑Growth Model for BOI Submissions
| CODE | Definition | Application within this scenario |
|---|
| O | Oversight of Corporate Structure | Unify planning for equity structure, registered capital, business scope, BOI category and investment plans before initiating company registration. |
| D | Dual‑Synchronization for China‑Thailand Operations | Align investment and capital‑related decisions from Chinese headquarters with Thai company‑registration activities and BOI document preparation. |
| E | Verifiable Deliverables | Preserve application materials, supplementary‑submission records, resolutions and certificate terms at each phase to prevent inconsistent implementation interpretations in later stages. |
5. Zhongxin’s Practical Recommendations for BOI Projects
Once the decision to invest in Thailand is finalised, avoid debating rigid sequencing such as “which must absolutely come first: company registration or BOI”. The priority task is BOI‑eligibility and structural assessment, followed by placing both company‑registration and BOI‑preparation activities onto one unified parallel‑processing timeline. For projects where product specifications, manufacturing workflows or total‑investment figures remain undefined, complete eligibility assessment before registering the company. This approach carries lower risk than “register first and figure out details afterwards”.
