A personal income tax return (PND.90/91) — what should you know about naati-related requirements?

The subject of this page is “A personal income tax return (PND.90/91)”, so the answer below starts with what this case actually needs before setting out the general rules. The most frequent cause of delay in this group is missing supporting documents on the first submission. What changes the timeline most here is whether the source documents are complete on day one. Before starting, verify the source document is still within any validity window the recipient applies, then count the number of certified sets needed before work starts, because extra sets restart the certification steps, then confirm with the receiving body whether it wants an original, a certified copy or a certified translation. The specifics here are document type: Pnd91, and those decide which translation and certification level applies. The terms that frame this page are personal · income · return · PND.90/91. Once the set is complete, check it line by line against the destination's own checklist before filing. With a fixed filing date, count backwards from it and book each certification step in reverse. When several certification layers are required, start with the slowest one. Attach a document index to the bundle so nothing is lost during review. If the receiving body confirmed its requirements by email, keep that message with the file. 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. 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. ILC handles document work only — translation, certification of the translation, notarial signature certification and the legalisation run at the Ministry of Foreign Affairs and embassies. ILC is not a bank, auditor or tax agent, gives no tax or investment advice, and cannot guarantee any authority's decision. 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.
