Which documents are needed for VAT registration with the Revenue Department?

The case under review is “Which documents are needed for VAT registration with the Revenue Department”, so it covers both the requirements attached to this document set and the order the steps must follow. With a fixed filing date, count backwards from it and book each certification step in reverse. Documents with a short validity window should be produced as close to the filing date as possible. 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. What sets this case apart is the number of certified sets and the window in which they must be used. The condition most often overlooked is that name spelling must match across every document in the set. The terms that frame this page are documents · needed · registration · Revenue. After certification, scan the full set before it leaves your hands. When filing for a company, attach current evidence of signing authority. Most licences carry an expiry date, so plan renewal ahead of the deadline. Note who signed each certification and on what date for later reference. Keep a copy of every source document plus the receipt or docket from each step. VAT registration sits in the Revenue Code: a business whose VAT-liable revenue exceeds 1.8 million baht a year must apply to the Revenue Department (form Phor.Phor.01) and receives the VAT certificate, form Phor.Phor.20. Foreign counterparties and banks routinely ask to see that certificate when opening accounts or signing contracts. A Thai corporate document used overseas is normally translated in full — including seals and signatures — then the translation is certified by the Legalisation Division, Department of Consular Affairs, Ministry of Foreign Affairs, and finally by the destination country's embassy or consulate where that country requires it. Thailand is not a party to the 1961 Apostille Convention, so no apostille is issued for Thai documents. ILC handles the document side: translation, certification of the translation, assembling the set against the authority's checklist, and coordinating the MFA and embassy steps. ILC is not counsel of record for a licence application, gives no legal ruling, and cannot guarantee how a licensing authority will decide. Cost and lead time depend on page count, target language, how many certified sets are required and the steps the receiving authority sets, so every file is quoted before work starts.
