A working guide to thai vat registration in Thailand

Thai VAT Registration can involve different document checks depending on the receiving authority. Confirm the intended use and destination before arranging translation, a notarial signature, or consular legalization. For a review of your specific companies crossing the VAT threshold or importing goods matter, contact us on LINE @THAIL or by email at Contact@thailaw-accounting.co.th.

Documents to discuss for companies crossing the VAT threshold or importing goods may include company affidavit (Nor Sor 3), shareholder list (Bor Or Jor 5), office lease & house registration, map of office, director's ID, power of attorney; confirm the final checklist with the receiving authority. Check the current acceptance criteria with the Thai Revenue Department.

How the workflow runs end-to-end

First identify the issuing authority, the person signing, the destination and the receiving body's current requirements. The necessary steps may include translation, certification or consular legalization, but not every document needs every step. Confirm the sequence before sending originals.

VAT registration in Thailand: who must register and how

Businesses expected to exceed the statutory annual revenue threshold must register for VAT; others may register voluntarily to reclaim input VAT or to work with larger clients. The Revenue Department checks that your registered address is a genuine place of business, so the location documents matter as much as the form itself.

Documents for PP 01 registration

  • · Company certificate and memorandum from the DBD
  • · Lease or consent-to-use letter for the registered address, with the owner's documents
  • · Photos of the office and a location map
  • · Directors' ID cards or passports

After registration

  • · Issue full tax invoices for VAT-able sales
  • · File PP 30 every month, even with no sales
  • · Keep input and output VAT reports

More frequently asked questions

Can I register VAT using a virtual office address?

Yes. Our Virtual Office addresses at both the Khon Kaen head office and the Bangkok (Lat Phrao 95) branch support VAT registration. You must have the right to use the premises, display a company sign, and allow Revenue Department officers to inspect the location. Our team prepares the consent documents and helps you get ready before filing.

Will the Revenue Department visit the office?

They may inspect the address. We explain what officers typically check so you are prepared.

When is the PP 30 VAT return due?

Every month, even with no sales. Paper filing is due by the 15th of the following month; online filing may be extended under the Revenue Department announcement in force.

What extra records does a VAT registrant keep?

An output tax report, an input tax report and, for businesses with goods, an inventory report. Tax invoices and supporting documents should be kept for at least 5 years.

What must a full tax invoice show?

At minimum: the words 'tax invoice', the seller's name, address and tax ID, the buyer's name and address (and tax ID if VAT-registered), the invoice number, a description of goods or services, the value, the VAT shown separately, and the issue date.
