THAILAND REGIONAL HEADQUARTERS
Regional Headquarters Setup in Thailand: Entity, Functions, and Incentives
Build the headquarters around its Thai legal person, group services, and approval route.
A regional headquarters is an operating role, not a separate Thai company form. For the current incentive route, plan around a Thai-incorporated company seeking BOI promotion as an International Business Center (IBC), activity 10.1.2. Its services must match the approved group-service scope; tax treatment then requires a separate Revenue Department approval, and foreign-currency treasury functions need their own Bank of Thailand authorization.
The numbers apply to different gates: the 2026 BOI Guide requires at least THB 10 million paid-up registered capital and 10 skilled staff (or 5 for a treasury-only project); the Revenue Department’s standard IBC tax-rate tiers start at THB 60 million of eligible expenses paid in Thailand. Do not budget every headquarters function, dividend, trade flow, or expatriate salary as automatically tax-favoured.
Key takeaways
- A regional-headquarters plan usually uses a Thai company; “regional headquarters” describes the function, while IBC is a BOI activity and a separate tax status.
- The current BOI category is activity 10.1.2. It requires a plan for listed services to associated enterprises, at least THB 10 million paid-up capital, and skilled staff.
- BOI, Revenue Department, and Bank of Thailand approvals answer different questions; a certificate from one agency does not replace another agency’s license or tax approval.
- New IBC tax benefits are conditional. Standard company CIT tiers of 8%, 5%, or 3% are linked to qualifying local expenses of THB 60 million, THB 300 million, or THB 600 million per accounting period.
- International-trade income is not covered by the IBC corporate-income-tax reduction; a qualified expatriate may have a separate 15% personal-income-tax rate subject to its own conditions.
Define a regional headquarters in Thailand
The words “regional headquarters” can describe a management centre, a shared-services company, a holding company, a treasury function, or a trading hub. They do not, on their own, identify the legal person, reserve an activity under Thai law, or confer tax treatment. The useful starting record is a function map: each service, who receives it, where the recipient is incorporated, which Thai entity performs it, and what contract and invoice support the charge.
For a new incentives-led headquarters, the current route to screen is the BOI’s International Business Center (IBC), listed in the 2026 Investment Promotion Guide as activity 10.1.2. The Revenue Department uses “IBC” for a Thai-law company approved under Royal Decree No. 674 B.E. 2561 (2018) . Older names such as International Headquarters (IHQ), International Trading Center (ITC), and Regional Operating Headquarters (ROH) still appear in historical laws, FAQs, or transition rules; they should not be treated as fresh entity types or assumed incentives for a new project.
This distinction changes the decision. The BOI activity evaluates an investment-promotion project and its commitments; the Revenue Department decides whether the company qualifies for tax benefits. A regional-office name in a company profile or board resolution is not a substitute for either decision. Start from the planned operating activity and group relationships, then choose a legal entity that can lawfully perform that activity.
Choose the operating entity
The legal form and incentive designation sit at different levels. A Thai private limited company can be the regional operating company and BOI applicant; its shareholder mix, service scope, tax position, and foreign-business permissions then need to fit the proposed work. The Revenue Department’s IBC definition is specific to a company incorporated under Thai law, so a foreign parent’s branch should not be assumed to qualify for that tax regime.
| Layer | What it is | Question before filing |
|---|---|---|
| Thai private limited company | A Thai-law company with shareholders, directors, articles, accounts, and its own contracts and obligations. | Will it own staff, service contracts, group assets, and the proposed IBC commitments? |
| Foreign-company branch | A Thai registration of the foreign parent’s presence, not a Thai-incorporated subsidiary for the IBC tax definition. | Does direct parent operation fit the FBA permission, branch registration, tax, and liability plan? |
| BOI IBC activity | Investment-promotion status for listed group services under activity 10.1.2; it is not a separate company-law form. | Do the services, staff, capital, and project plan match the current BOI Guide and certificate? |
| Revenue Department IBC approval | A separate tax approval for eligible IBC income and benefits under the Revenue Code framework. | Can the company show qualifying services, associated enterprises, expense thresholds, and staff records? |
A foreign-majority shareholder may be possible for an approved IBC project under the BOI’s IBC guidance , but ownership permission is not a general waiver for every business activity. Check the activity-specific FBA position, any BOI certificate conditions, and the actual share and control structure before the Thai company signs local contracts. For general Thai entity formation, prepare the Thailand company registration requirements alongside the BOI plan so the filed company purpose and proposed operation do not contradict each other.
Test the headquarters entity before incorporation
Align the foreign ownership plan, group services, and proposed IBC activity with the actual Thai operating company.
Map functions to IBC activity 10.1.2
An IBC application is strongest when the business plan describes services the Thai team will actually deliver to associated enterprises, rather than a broad “regional management” label. The BOI Guide lists management and business planning, raw-material procurement, product R&D, technical support, marketing and sales promotion, HR and training, financial advisory, economic and investment analysis, credit management, treasury-center financial management, international trade, certain lending, building rental to associates, and other approved support functions.
| Function family | What the Thai team might deliver | Evidence to connect to the plan | Boundary to test |
|---|---|---|---|
| Management and coordination | Planning, reporting, shared administration, and business coordination for group companies. | Organisation chart, service catalogue, affiliate list, service agreements, staffing plan, and cost allocation. | Which affiliate receives the service, and how is the fee supported? |
| Technical, product, and commercial support | Product R&D, technical support, procurement information, marketing, training, and credit control. | Work descriptions, deliverables, employee qualifications, locations, sample reports, and development records. | Is the service within a named activity, or does it cross into an independently restricted service? |
| Treasury and lending | Financial management of a Treasury Center or permitted lending to associated enterprises. | BOT license, group-company structure, borrowing/lending policy, cash-flow diagram, and authorization matrix. | BOI promotion does not grant the Bank of Thailand's foreign-exchange license. |
| International trade | Cross-border buying and selling or related goods services, if the IBC project includes that scope. | Goods, seller/buyer roles, title transfer, invoices, import/export documents, and included service functions. | Trade requires core IBC service activity; trade income is not eligible for IBC CIT-rate reduction. |
The BOI Guide sets at least THB 10 million in paid-up registered capital and at least 10 knowledgeable staff for the IBC project. A project providing only treasury-center financial management to associated enterprises may use a five-skilled-employee threshold. If international trading or building-rental services are included, at least one core service scope from items 1.1–1.10 must also be involved; lending must be paired with at least one of scopes 1.1–1.9. The approved certificate and current guidance determine the scope actually permitted.
Do not collapse every group activity into a service label. A Thai team that provides technical support, procures goods for another entity, rents a building to an affiliate, and manages foreign currency may cross multiple legal and tax regimes. Separate each function in the service catalogue, contracts, invoice lines, cost centres, and authorization records.
Separate BOI, RD, and BOT approvals
A regional centre may need separate agency approvals , but each decision has a different object. The diagram follows the order of proof: establish the legal person, obtain project promotion, apply for tax treatment, then add the Treasury Center license only if the plan manages foreign currency for affiliated companies.
The 2026 BOI Guide identifies IBC as activity 10.1.2 and places it in Group B. Its current conditions include the paid-up capital and staffing tests; its machinery import-duty relief is limited to machinery used for R&D and training. This is distinct from the Revenue Department’s IBC tax regime. The Revenue Department maintains a separate IBC approval page with Royal Decree No. 674, the tax notification, and the Sor.Kor.Ror.1 form.
A company seeking financial management services of a Treasury Center must also satisfy the Bank of Thailand’s foreign-exchange rules. The BOT’s Treasury Center guidance describes authorized non-bank companies that manage foreign currency for affiliated enterprises, covering re-invoicing or payment agency, netting, foreign-currency transactions and exchange-rate risk, and liquidity management. Do not activate those functions based only on a BOI IBC application.
Separate project, tax, and treasury workstreams
Create one authority-and-evidence map before requesting promotion, tax treatment, or foreign-exchange permission.
Compare the incentive layers
The BOI, Revenue Department, and BOT benefits are not a single “regional headquarters incentive package.” Build the budget by separating non-tax permissions, eligible corporate or personal tax treatment, and financial-market authorization.
| Authority | Potential benefit | Key condition or limit |
|---|---|---|
| BOI promotion | For qualifying IBC projects, BOI materials identify foreign-majority ownership, permission to own land, foreign experts, and specific machinery import-duty relief. | Benefits depend on the BOI certificate and applicable conditions; machinery relief is for R&D and training, not a general equipment or raw-material exemption. |
| Revenue Department tax approval | Qualifying IBC service profits may receive 8%, 5%, or 3% CIT tiers; qualifying dividends and treasury-center receipts can have separate exemptions; some expatriates may elect a 15% PIT rate. | The standard tiers start at THB 60m, THB 300m, and THB 600m of eligible expenses paid to recipients in Thailand. International-trade income is excluded from the IBC CIT-rate reduction. |
| Bank of Thailand | A Treasury Center permit can authorize defined foreign-currency management for group companies. | Only needed for Treasury Center functions; it is a separate permission under exchange-control rules. |
| DBD and operating regulators | Company registration, foreign-business certificates or licenses where required, and activity-specific approvals. | BOI promotion does not remove separate legal, tax, employment, data, or sector obligations. |
The standard Revenue Department regime, set out in its IBC Royal Decree , provides 8% CIT on eligible IBC income when qualifying expenses paid to Thai recipients reach THB 60 million per accounting period, 5% at THB 300 million, and 3% at THB 600 million. These rates do not apply to every company profit: international trading is excluded from the IBC CIT reduction, and a converted legacy IHQ/ROH company may have transition rules. The IBC tax approval generally runs for up to 15 accounting periods, subject to continuing qualifications.
A 15% PIT option for qualifying expatriate employees is not automatic. The Revenue Department’s IBC tax notification sets employee and work-permit requirements, including average employment income of at least THB 200,000 for each month in Thailand and at least 180 days of Thailand stay in the tax year (with first- and last-year exceptions), plus separate reporting and election conditions. The same person may face different treatment if income comes from another employer or the employee misses a qualifying condition.
Prepare the application evidence file
Both the BOI project file and the Revenue Department tax application need the group structure and planned operations to line up. A weak affiliate list, generic staffing plan, or unexplained service fee can undermine the business rationale even when the company has registered and the management team has approved the relocation.
| Evidence item | What it needs to show | Why the reviewer needs it |
|---|---|---|
| Group chart and associate list | Direct and indirect ownership or control links, country, legal name, and ownership percentages for each recipient. | Connects service recipients to the IBC definition of associated enterprises. |
| Service catalogue and agreements | Each service, deliverable, recipient, location, fee method, and accountable Thai team. | Maps actual activities to the BOI scope and eligible Revenue Department income. |
| Business and investment plan | Regional rationale, operating model, premises, implementation steps, and three-year projections where requested. | Supports the BOI application and the RD tax-benefit request. |
| Capital, payroll, and cost forecast | Paid-up capital, skills and roles of at least 10 staff (or qualifying treasury-only staffing), payroll, and expenses paid to Thai recipients. | Tests BOI commitments and the separate IBC tax thresholds period by period. |
| Treasury and expatriate records | BOT permission and group cash-flow scope; employee qualifications, income, stay, and work authorization for a tax-rate request. | Separates regulated money-management activity and individual tax eligibility from the IBC project. |
The Revenue Department’s current IBC page lists the IBC approval system, the governing decree, the tax notification, and the application form. Its notification asks for a business plan, Thai and foreign associate details, skilled-employee information, and expatriate details where PIT relief is requested. The BOI filing is a separate project submission through e-Investment; maintain one underlying fact set but tailor each application to the authority’s test.
Sequence the headquarters launch
Sequence planning around the condition that can block the next step. Do not hire to a projected headcount without assigning real IBC work; do not book an expected tax rate before approval; and do not route foreign-currency transactions through a Treasury Center until its permit is effective.
- Map the operating functions, associated enterprises, service recipients, goods flows, foreign-currency activity, staff roles, and Thai work locations.
- Choose and register the Thai legal person; confirm its shareholders, directors, activity clauses, address, accounting setup, and any FBA route through the relevant DBD online service .
- Prepare the BOI IBC activity 10.1.2 plan, capital and staffing commitments, affiliate evidence, and separate project scopes for trading, lending, or building rental.
- Submit the BOI investment-promotion request and wait for the project decision and certificate before relying on BOI project rights.
- File the separate Revenue Department IBC tax application; model qualifying income, local expenses, the accounting period, expatriate eligibility, and ongoing reporting.
- If treasury activity is planned, obtain the BOT permit and finish the foreign-exchange controls, bank processes, staff authorization, tax, and intercompany agreements before using that function.
BOI project approval periods are counted from a complete application under the relevant project-value band and are only one part of launch timing. Entity registration, corrections, Revenue Department review, BOT licensing, bank due diligence, foreign staff, office fit-out, and service agreements add separate workstreams. Set an internal go-live date only after each authority’s output and the operating prerequisites have been checked.
Select the route for your plan
Choose an IBC project when a Thai company will provide defined services to associated enterprises and can meet the capital, staffing, business-plan, and ongoing commitments. Add the Revenue Department tax request only if the projected eligible services and expense profile support it. Add a Treasury Center application only if the group needs regulated foreign-currency services.
If the proposed Thai presence will mainly own or sell goods, act as a distributor, or support customers unrelated to the group, examine the trading and foreign-business permissions separately rather than assuming IBC promotion covers the whole model. If treasury is the main function, begin with the BOT license rules and then match the IBC service scope and tax file to that licensed activity.
Where the overseas parent is still choosing between a Thai company, a branch, and direct operating presence, use a foreign parent’s Thailand entry options to frame that entity decision, then evaluate IBC eligibility against the services the Thai team will actually deliver.
Before the first group-service invoice, be able to show who performed the work, which affiliate received it, how the price was set, and which approved scope supports the activity. Promotion, tax approval, and a Treasury Center permit solve different problems.
Check the IBC and tax conditions against projected operations
Review the approved activity, affiliate services, staff, local expense, and optional treasury functions before the headquarters starts operating.
Frequently asked questions
Is a regional headquarters a separate company type in Thailand?
No. It describes a function. A Thai private limited company is a common operating entity, while IBC is an activity and separate approvals may be available from BOI and the Revenue Department. The Revenue Department’s IBC tax definition requires a Thai-law company.
What are the current BOI IBC thresholds?
The 2026 Guide lists at least THB 10 million paid-up registered capital and 10 skilled staff, or 5 staff if the project only provides treasury-center financial management services to associated enterprises. The approved activity scope and certificate still control the project.
Does BOI promotion automatically grant the IBC tax rate?
No. The Revenue Department has a separate IBC tax approval process with service, associate, capital, staff, expense, and recordkeeping conditions. BOI promotion and RD tax approval should be tracked as separate applications and outputs.
Can international-trade revenue receive IBC’s reduced corporate tax rate?
The Revenue Department’s IBC material says international-trade income is excluded from the reduced IBC CIT rate. An IBC may qualify for other IBC-related treatment, including an expatriate PIT benefit, if the applicable conditions are met.
Does an IBC need a Bank of Thailand Treasury Center license?
Only if it will carry out regulated Treasury Center activities such as group re-invoicing, payment agency, netting, foreign-currency management, or liquidity services. BOI IBC promotion alone is not the BOT authorization.
