Submitting a corporate income tax return (PND.50/51) to South Korea — how must it be translated and certified?

The subject of this page is “Submitting a corporate income tax return (PND.50/51) to South Korea”, so it flags what usually causes documents like this to be rejected before summarising the general practice. After certification, scan the full set before it leaves your hands. With a fixed filing date, count backwards from it and book each certification step in reverse. Leave buffer time in case a translation has to be amended or a source document re-issued. Attach a document index to the bundle so nothing is lost during review. Note who signed each certification and on what date for later reference. The most frequent cause of delay in this group is missing supporting documents on the first submission. A key variable is the filing channel (in person, agent or online), which sets the copy format to prepare. Before starting, keep a digital copy of every page, including seals and signatures, then make sure document numbers, issue dates and issuing-office names match across the set, then ask in advance which category of certified translator the destination accepts. The specifics here are document type: Pnd50; destination: Kr, and those decide which translation and certification level applies. The terms that frame this page are Submitting · corporate · income · return. 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.
