Submitting a personal income tax return (PND.90/91) to Australia — how must it be translated and certified?

This question is specifically about “Submitting a personal income tax return (PND.90/91) to Australia”, so the answer below starts with what this case actually needs before setting out the general rules. The specifics here are document type: Pnd91; destination: Au, and those decide which translation and certification level applies. The terms that frame this page are Submitting · personal · income · return. The condition most often overlooked is that name spelling must match across every document in the set. The common failure in this group of cases is a translation that does not match the certification type required. Before starting, count the number of certified sets needed before work starts, because extra sets restart the certification steps, then verify the source document is still within any validity window the recipient applies, then check that names are spelled identically to the passport or ID card on every page. Leave buffer time in case a translation has to be amended or a source document re-issued. If multiple certified sets are needed, order them all in the first round to avoid re-queuing. If the receiving body confirmed its requirements by email, keep that message with the file. Note who signed each certification and on what date for later reference. The next step is confirming the filing channel and the copy or file format required. 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. Non-English documents filed with Australian authorities need a NAATI-certified translation carrying the stamp, practitioner number and certification date. ImmiAccount accepts an upload bearing a complete certification block, and in ordinary cases no further embassy legalisation is required. 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.
