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

The issue to settle here 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. 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. Plan the schedule with room for at least one review cycle at the receiving office. If multiple certified sets are needed, order them all in the first round to avoid re-queuing. After certification, scan the full set before it leaves your hands. The terms that frame this page are personal · income · return · PND.90/91. The specifics here are document type: Pnd91, and those decide which translation and certification level applies. 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 deciding factor is the receiving body's requirement, not only the format of the Thai-side document. A key variable is the filing channel (in person, agent or online), which sets the copy format to prepare. Thailand has no common-law notary public. Signature certification, true-copy certification and affidavits are handled by a Notarial Services Attorney registered under Lawyers Council of Thailand rules, and that is the route used when an overseas office asks for notarisation of a financial document. 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. 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.
