Q1122. How to translate foreign corporate income tax payment receipt documents?

Answered by the NYC Visa & Translation certified translation team

Foreign corporate income tax payment receipts come into Thai practice for foreign tax credit claims, permanent establishment questions, and group tax reporting. The governing framework: Thailand's foreign tax credit rules (Section 65 bis of the Revenue Code and the double tax treaties) allow credit for foreign tax paid on foreign-source income, and the Revenue Department requires evidence of the foreign tax actually paid — the foreign tax authority's assessment or payment receipt, translated into Thai and certified. The translation workflow: the foreign tax receipt or assessment is legalised through the chain where the Revenue Department requires it (for formal claims, expect the full chain: origin-country authentication, Royal Thai Embassy legalisation, Thai translation, MFA certification), and the translation must preserve the receipt's substantive content: the taxpayer's identity (matching the Thai claiming entity), the tax period, the tax type, the amount in the original currency with the payment date, and the issuing authority. Points that matter: the credit calculation uses the exchange rate rules of the Revenue Code — the translation preserves the original currency amounts, and the conversion is the accountant's work, not the translator's; where the foreign receipt covers consolidated group tax, the allocation to the Thai-relevant entity must be evidenced separately; and treaty relief claims (reduced withholding rates) use the foreign tax authority's residence certificate, which is a different document with its own chain. Practice points: the Revenue Department's examination can come years after the filing — keep the legalised translated evidence with the tax file; and for recurring claims, establish the document chain as a repeatable annual process. Confirm the Revenue Department's current evidential requirements with the handling tax adviser.
