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

This question is specifically about “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 point to fix before starting is the real deadline, so the steps can be scheduled backwards from it. The common failure in this group of cases is a translation that does not match the certification type required. 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 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. After filing, follow up on the cycle the office states rather than waiting past the deadline. If multiple certified sets are needed, order them all in the first round to avoid re-queuing. Public holidays and embassy closures move certification queues more than most people expect. Note who signed each certification and on what date for later reference. Record the reference number of each certification layer; it is the fastest way to trace status. 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. Financial documents are issued by the account-holding institution and tax documents by the Revenue Department or the withholding agent. A translation provider cannot issue, amend or vouch for the figures; its role is to render the text and numbers exactly — letterhead, seal, document number, signature block and dates included. 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.
