Offshore structure and Thailand investment
Many foreign investors use offshore holding companies alongside Thai operating entities for tax efficiency, asset protection, and group treasury. At Thai Visa Centre in Bangkok, we help executives entering Thailand on lawful visas regardless of where the parent company is incorporated.
Offshore structures do not exempt Thailand operations from FBA, BOI, tax, or work-permit rules. The Thai entity must comply locally. Thai operating choices: limited company guide.
Offshore structures do not exempt Thailand operations from FBA, tax, or work-permit rules.
Related-party fees, royalties, and loans must meet Revenue Department scrutiny.
Singapore and Hong Kong often used for treaty networks and regional treasury.
Work permits require employment contract with the Thai entity, not only offshore payroll.
Why combine offshore and Thai entities?
| Reason | Detail |
|---|---|
| HoldCo in Singapore, HK, or BVI | Owns Thai operating subsidiary for group investment and exit planning. |
| IP holding abroad | Licences technology to Thai company with transfer pricing documentation. |
| Treasury centre | Group lending and cash pooling across regional affiliates. |
| Exit planning | Share sale at HoldCo level in M&A transactions. |
| Treaty routing | Double tax agreement planning with economic substance requirements. |
Thailand compliance regardless of offshore layer
| Requirement | Applies to |
|---|---|
| Foreign Business Act | Applies to Thai entity activity regardless of offshore parent jurisdiction. |
| Transfer pricing | Related-party transactions must be at arm's length with documentation. |
| CIT and WHT | Thai-source income subject to corporate tax and withholding rules. |
| BOI conditions | If promoted, local substance and reporting requirements apply. |
| Work permits | Foreign staff in Thailand need permits sponsored by the Thai employer. |

Transfer pricing and substance
Management fees
Offshore to Thai company charges scrutinised for substance and benefit.
Royalties
IP royalties with low offshore substance face challenge.
Related-party loans
Interest rates subject to thin capitalisation rules.
Re-invoicing
Profit shifting through intermediary invoicing is high audit risk.
Immigration for group staff: Executives assigned to Thai OpCo need employment contract with the Thai entity, non-immigrant B visa, and work permit. Secondment letters must align with permit job description.

Common structure mistakes
- Thai company with no substance: single employee with all fees routed offshore.
- Branch remitting profits without withholding tax analysis.
- Foreign director paid only offshore, creating Thai PIT and work permit mismatch.
- Using offshore entity to invoice Thai clients without FBA licence.
- CRS or FATCA non-reporting on offshore accounts linked to Thai residents.
Frequently asked questions
General answers on offshore structures with Thai operations. Confirm structure with corporate and tax advisors before investing.
Q:Can a BVI company own 100% of a Thai company?
A:Only if FBA, BOI, or Amity permits. Offshore jurisdiction does not bypass Thai foreign ownership law.
Q:Is Singapore HoldCo plus Thai subsidiary standard?
A:Common and legitimate when supported by economic substance and transfer pricing compliance.
Q:Do offshore directors need Thai work permits?
A:Only if they perform work physically in Thailand for the Thai entity.
Q:Does Thailand tax worldwide income of companies?
A:Thai companies are taxed on net profit under Thai CIT rules. Offshore parent taxation is separate.
Q:What transfer pricing documents are required?
A:Master file, local file, and Country-by-Country reporting for large groups. Smaller groups still need arm's length support.
Q:Can SMART Visa apply to offshore group staff?
A:SMART Visa may apply for qualifying tech roles employed by the Thai entity, not merely by an offshore parent.
Q:How does BOI evaluate offshore investment?
A:BOI evaluates the project in Thailand: capital, employment, and activity. Offshore HoldCo ownership is common; benefits attach to the promoted Thai entity.
Q:Does offshore parent presence create work rights?
A:No. Offshore parent presence alone does not create legal work rights in Thailand. Thai entity sponsorship is required.
