Setting up a business in Thailand with Board of Investment (BOI) promotion can offer significant advantages. However, the application process requires careful preparation and compliance with specific requirements. In this guide, we walk you through the step-by-step BOI application process in Thailand. We focus on clear, practical advice to help you navigate the process smoothly and understand what to expect.
Understanding the Thailand BOI Process Guide
The Thailand BOI process guide is designed to help foreign founders and foreign-owned SMEs understand how to apply for investment promotion benefits. The BOI offers incentives such as tax exemptions, land ownership rights, and work permit facilitation. However, these benefits come with strict compliance requirements.
Here’s what you need to know upfront:
The BOI application is discretionary. Approval depends on the project’s alignment with Thailand’s investment priorities.
Documentation must be accurate and complete.
Timelines vary depending on the complexity of your project and the BOI’s workload.
Fees and costs are transparent but can vary based on your business type and size.
We recommend preparing all documents carefully and consulting with experts to avoid delays or rejections.

Step 1: Prepare Your Business Plan and Documents
Before submitting your BOI application, you must prepare a detailed business plan. This plan should clearly explain your project, including:
Business objectives and scope
Investment amount and sources of funds
Technology and machinery to be used
Employment plans and skills development
Environmental and social impact considerations
Alongside the business plan, gather these essential documents:
Company registration documents (if already registered)
Identification documents of shareholders and directors
Financial statements or proof of capital
Technical licenses or permits (if applicable)
Make sure your business plan aligns with the BOI’s targeted industries and investment promotion policies. This alignment increases your chances of approval.
Step 2: Submit the BOI Application
Once your documents are ready, you can submit your application to the BOI. The application includes:
Completed application form
Business plan and supporting documents
Application fee payment receipt
The BOI will review your submission for completeness and compliance. They may request additional information or clarifications during this stage.
The review process typically takes 30 to 60 days, but it can be longer depending on the project’s complexity.
We recommend tracking your application status regularly and responding promptly to any BOI requests.
Step 3: BOI Application Review and Site Visit
After the initial document review, the BOI may conduct a site visit to verify your project details. This visit helps confirm:
The accuracy of your business plan
The suitability of your location and facilities
Compliance with environmental and safety standards
Prepare for the site visit by ensuring your premises and documents are organized and accessible.
The BOI’s decision will be based on the overall assessment, including the site visit findings.
Step 4: BOI Approval and Issuance of Promotion Certificate
If your application is approved, the BOI will issue a promotion certificate. This certificate outlines the incentives granted and the conditions you must follow.
Typical incentives include:
Corporate income tax exemptions for a specified period
Import duty exemptions on machinery and raw materials
Permission to own land (in some cases)
Facilitation of work permits and visas for foreign employees
The certificate will also specify reporting requirements and compliance obligations.
Keep in mind that the BOI can revoke or modify incentives if conditions are not met.
How much does it cost to register a business in Thailand?
Registering a business in Thailand involves several fees, which vary depending on the company type and capital. Here’s a general breakdown:
Company registration fee: Approximately 5,500 THB for a limited company with registered capital up to 1 million THB.
BOI application fee: Typically ranges from 10,000 to 50,000 THB depending on the project size.
Legal and consulting fees: These vary widely but expect to budget for professional assistance to ensure compliance.
Other government fees: Such as VAT registration, social security, and work permit fees.
Budgeting for these costs upfront helps avoid surprises during the setup process.
Step 5: Post-Approval Compliance and Reporting
After receiving BOI promotion, your responsibilities continue. You must:
Submit annual reports on investment progress and employment
Maintain proper accounting records and financial statements
Comply with environmental and labor regulations
Renew work permits and visas for foreign staff as required
Non-compliance can lead to penalties or loss of BOI privileges.
We advise setting up a compliance calendar and working with trusted advisors to stay on track.
