Before paying an overseas service provider, review the actual service, contract, recipient country, place of performance, place of use, amount, treaty position and supporting documents.
The invoice description alone does not determine withholding tax or VAT treatment. A “consulting fee” or “software fee” still needs a review of the transaction before payment.
1. Start with the actual service
Read the scope of work and identify what the provider did. Separate advice, technical work, installation, access to software, licensing, advertising, commission, training and reimbursement where the agreement treats them differently.
Ask where the people performed the work, where the customer received the benefit, what rights were granted and whether the Thai company could use the output in Thailand. “Management fee” is a billing label; it is not a complete tax analysis.
2. Review Thai withholding tax
The Thai payer needs to consider whether the payment is a type of income subject to withholding under Thai rules. The answer depends on the nature of the payment, the recipient, the contract and the circumstances of the work.
Avoid applying one withholding rate to every overseas payment. Once the transaction has been classified, confirm the form, deadline, certificate and evidence required. The Revenue Department’s withholding tax resources (opens in a new tab) provide the official forms and filing instructions.
3. Check whether a double tax agreement is relevant
If the recipient is resident in a treaty country, examine the treaty article that could apply to the income. Business profits, royalties, interest, technical services and other categories do not all use the same analysis.
Also check whether the overseas enterprise has a permanent establishment or other taxable presence relevant to the payment. Treaty relief is not automatic: the country, income classification, residence evidence, contract and actual performance all matter. Keep the certificate or other supporting evidence required for the position taken.
4. Review VAT on services from overseas
VAT needs its own review. Revenue Department Order P.104/2544 addresses services performed outside Thailand and used in Thailand. In that situation, the Thai recipient can have a VAT responsibility under the relevant rules. The result depends on the service and the facts, so keep the contract, invoice and explanation of where the service was used.
Read the Revenue Department Order P.104/2544 (opens in a new tab) together with the company's VAT position and current filing practice. A withholding tax conclusion does not answer the VAT question.
5. Review withholding tax and VAT together with the contract
Tax treatment affects the amount the provider receives, the amount the Thai company pays, the wording of the invoice and the documents issued after payment. Decide whether the quoted price is gross or net of withholding, who bears bank charges and how any VAT responsibility will be recorded.
Complete the tax review before approving payment. Missing certificates or insufficient withholding are harder to resolve after the funds have been transferred overseas.
6. Intercompany service payments need extra evidence
An intercompany invoice alone is not enough to support the charge. Keep the service agreement, charging basis, invoice, evidence of work, allocation method, recipient-country information and evidence of the benefit to the Thai company.
Where the charge is shared among group companies, explain the allocation key and retain the underlying cost records. The arrangement may also be relevant to transfer pricing, but that question needs its own review; an invoice alone does not establish an arm's-length result.
7. Questions to review before payment
- What did the provider actually do, and is the scope split into different types of service?
- Where was each part of the work performed?
- Where was the service used or received?
- Who is the legal recipient, and in which country is it resident?
- Is the recipient related to the Thai payer?
- What does the contract say about gross-up, tax certificates and payment currency?
- Is there residence evidence or other treaty documentation?
- What evidence proves the service and the benefit to the Thai company?
- How will the payment be recorded for withholding tax, VAT and accounting purposes?
Example: Thai subsidiary paying an overseas group company
A Thai subsidiary receives an invoice from its regional parent for “management and technical services.” Before approving it, the finance team should split the work described, obtain the agreement and service evidence, confirm where staff performed the work, identify the parent company's country of residence, check treaty documentation, review whether the services were used in Thailand and document the withholding and VAT analysis.
Those facts may lead to different outcomes for different parts of the invoice. The example does not support a definitive tax answer without the documents and transaction details.
