Submitting a withholding tax certificate (50 bis) to South Korea — how must it be translated and certified?

The point raised here is “Submitting a withholding tax certificate (50 bis) to South Korea”, so the answer below starts with what this case actually needs before setting out the general rules. Plan the schedule with room for at least one review cycle at the receiving office. For documents going abroad, include international shipping time in the plan. High-resolution photos of seals and signatures help when the destination asks for re-verification. Keep a copy of every source document plus the receipt or docket from each step. The next step is confirming the filing channel and the copy or file format required. The specifics here are document type: Wht50; destination: Kr, and those decide which translation and certification level applies. The terms that frame this page are Submitting · withholding · certificate · South. The most frequent cause of delay in this group is missing supporting documents on the first submission. The deciding factor is the receiving body's requirement, not only the format of the Thai-side document. Before starting, make sure document numbers, issue dates and issuing-office names match across the set, then keep a digital copy of every page, including seals and signatures, then plan the timeline so certification finishes before the real filing deadline. The standard route for a Thai document used abroad is: obtain the original or an issuer-certified copy, translate it faithfully, certify the translation, have it legalised by the Legalisation Division of the Department of Consular Affairs at the Ministry of Foreign Affairs, then, if the destination requires it, legalised again at that country's embassy. A financial translation must preserve figures, currency, dates, account numbers and balances exactly as printed — no rounding, no currency conversion, no summarising of transaction lines. The source date format should be kept with the Buddhist or Gregorian era stated explicitly so the receiving office cannot misread it. Thailand does not issue Hague Apostille certificates, so Thai documents still follow the consular legalisation route via the Department of Consular Affairs and the destination embassy. If a receiving office asks for an apostille, confirm with that office whether legalisation is accepted instead. Cost and lead time depend on page count, the volume of numeric tables, the target language and the certification steps required, so every file is quoted before work starts.
