A withholding tax certificate (50 bis) — what should you know about notary-related requirements?

The subject of this page is “A withholding tax certificate (50 bis)”, so the answer below starts with what this case actually needs before setting out the general rules. The specifics here are document type: Wht50, and those decide which translation and certification level applies. The terms that frame this page are withholding · certificate · know · notary-related. What sets this case apart is the number of certified sets and the window in which they must be used. A key variable is the filing channel (in person, agent or online), which sets the copy format to prepare. Before starting, confirm with the receiving body whether it wants an original, a certified copy or a certified translation, then check that names are spelled identically to the passport or ID card on every page, then verify the source document is still within any validity window the recipient applies. Plan the schedule with room for at least one review cycle at the receiving office. Documents with a short validity window should be produced as close to the filing date as possible. High-resolution photos of seals and signatures help when the destination asks for re-verification. Record the reference number of each certification layer; it is the fastest way to trace status. Once the set is complete, check it line by line against the destination's own checklist before filing. 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.
