Seven tax risks: Lump sum turn-key contracts in Thailand
The inefficiency of a lump sum turn-key construction contract under Thailand’s tax legislation
Thailand welcomes foreign construction companies for the erection of energy and infrastructure projects in the land of smile. From a commercial point of view, such big and financially strong foreign companies should be the offshore prime contractor under a lump-sum turnkey contract (LSTKC).
Such agreement covers typically the engineering, building construction, delivery of components, erection and assembling, site supervision as well as the start-up and initial operations. The offshore prime contractor will involve subcontractors outside of Thailand and local subcontractors in Thailand.
The tax disadvantage of such a structure is, that the entire revenue under the contract with the local principal is exposed to Thai taxes. This relates mainly to these three aspects:
- The sale of goods does not constitute a permanent establishment (PE), but in the case of a combined LSTKC, the service part of the agreement constitutes a PE for the whole scope of deliveries and services.
- Under Thai tax laws, there is no withholding tax on the sale of goods. However, in the case of a combined LSTKC, withholding tax on the full remuneration amount is due.
- Withholding taxes can be credited against corporate income tax obligations if any. However, although a tax cash refund is in general possible, such a request usually causes an aggressive tax audit and should be avoided.
These three main tax aspects make it typically unattractive for the parties to enter into an LSTKC as recommended by the FIDIC Silver Book.

The contract split as an effective tax planning tool
To reduce the overall tax burden, a locational split of the entire agreement into an onshore contract with an (often small) Thai company and an offshore contract with the foreign offshore contractor at the headquarters is required. This results in a split of the contract, a split of the contractors and a syndicated offer.
- The Thai onshore contractor, a Thai Co., Ltd., takes over the local engineering obligations. This includes local components, the erection respectively assembling, the building construction, site supervision, start-up and initial operations, procurement of onshore spare-parts as well as the onshore training of engineers and local staff in Thailand.
- The offshore contract of the local principal with the offshore contractor covers offshore design and engineering, several components, ownership transferred outside of Thailand, and offshore spare parts.
If done correctly, the split has substantial tax advantages: With respect to the offshore contract, profits are taxed abroad and no withholding taxes are due. Regarding the onshore contract, profits are low, the low withholding tax rate of 3% is deductible against profits, and stamp duty, if any, is reduced to the service part. As a result, the locational split qualifies as a highly effective tax planning tool.
Umbrella and consortium agreement – and why both are required
The local principal has good reasons to feel uncomfortable with the split of the combined LSTKC. Businesswise, the separation of obligations, risks, and responsibilities, is not his benefit. Therefore, for his comfort, it is required to add another agreement to the onshore and offshore contract, which can be drafted in the form of a letter agreement and acts as an overarching umbrella or coordination or wraparound for the onshore and offshore part. It has mainly three purposes:
- To assure that the service provider is financially capable to fulfill his obligations, including penalties and damage claims.
- To assure that the buyer/employer has no problem to address the correct contractual partner for claims and information requests.
- As a „horizontal defense“, it prevents the contractors from relying on the defaults of the other parties to avoid performing their contractual obligations.
Reasonable umbrellas typically take the form of complex agreements. If they are as simple as an enhanced parent company guarantee, this results in adverse tax consequences. Apart from the careful design of the contractual arrangements, it is essential to implement a legal contract management system to avoid that the red-lines are crossed which trigger an unwanted tax burden.
Providing loans or a guarantee are generally considered as providing service business pursuant to restricted business per List 3 of the Foreign Business Act. Loans or guarantees provided by the foreign offshore contractor (headquarters) in favor of the Thai onshore contractor might, therefore, be illegal. Under the Ministerial Regulation by the Ministry of Commerce as of June 25th, 2019, certain services provided to affiliates and group companies in Thailand are exempt from this requirement.
As an additional contract, a consortium agreement has to be concluded between onshore and offshore contractor. It deals with the rights and obligations of each member (allocation of costs, risks, internal chargeback), as a secondment agreements (transfer of employees and internal costs allocation), as a financing agreement (stand-alone conditions, no collateral in the project, no reference to the project), as well as for the agreed procedures.
Under Thailand’s tax jurisdiction, the form of separate agreements can be overruled by the substance. Therefore, the split of the combined agreement into two parts – and the addition of two additional agreements – is a highly sophisticated task and requires specific Thai and international tax know-how. Otherwise, the split could be irrelevant from the tax perspective and result in an even higher tax exposure.
International tax structuring for infrastructure and energy projects
The Thai Revenue Department is currently increasing its efforts to avoid tax deficits in connection with the upcoming of big infrastructure projects in the EEC, the OBOR-area and under the PPP-scheme. Experience shows, that Thailand’s tax authorities focus on the following seven weak points of the overall contractual structure:
#1. General misuse: If the functional split of the contracts is not made expertly, it will be qualified as artificial and irrelevant for the taxation of the entire venture. There are specific formal and material aspects which should be done right to avoid such judgment as misuse of tax-saving strategies.
It is an unnecessary naive approach to design onshore and offshore agreement with the same optical design, with the same definitions, parallel clauses and wordings. Instead, they should look at first sight as different as possible.
On the contractual side, it is highly risky to give the Thai principal the contractual rights to estimate the withholding tax rate at its own discretion after the contracts have been signed and concluded. Instead, the percentage has to be clearly concluded in the contract.
#2. Permanent establishment: The tax authorities will look for a Thai permanent establishment of the foreign offshore contractor in Thailand. This might base (i) on the documentation, (ii) on the factual handling, or (iii) on the onshore company acting as sole agent for the offshore company.
#3. Royalties: The services of the offshore contractor could be reclassified as royalties with a withholding tax rate of 15%. Thailand’s red tax lines between services and royalties and the policy of the Thai Revenue Department has to be carefully taken into consideration.
#4. Transfer pricing: The remuneration of all participants has to be adjusted to arm‘s length principles. Thailands transfer pricing rules and policies are currently in development and in practice a moving target.
#5. Umbrella agreement: A badly drafted umbrella agreement acts as a clamp which repeals and nullifies the effects of the split tax-wise. A joint and several liability for completing the project has not only legally, but even economically strictly avoided. Any direct, indirect or economical overriding of the locational split business transaction results in a collapse of the tax scheme. A proper contract design can be accomplished without a “Wrap Around Guarantee” (WAG).
#6. Non-disclosure: The umbrella agreement is typically not disclosed to the tax authorities. This is correct if it is really irrelevant tax-wise. Otherwise, the non-disclosure can be seen as a participation in a tax crime.
#7. Non-implementation: The clear and correct split of the LSTKC into onshore and offshore agreement has to be actually performed and executed to be relevant tax-wise. This requires sophisticated contract management under the supervision and monitoring of the tax lawyer.
The involvement of the foreign offshore contractor in the negotiations, the contract conclusion or the implementation of a subcontractor service agreement has to be avoided carefully with all means. Otherwise, it results in a collapse of the overall tax structuring scheme, followed by a high tax burden and other substantial disadvantages.
