Tax Invoice

A VAT-registered person must issue a ‘Tax Invoice’ to its customers containing the following mentions:

  • The wording ‘Tax Invoice’ in a prominent place
  • Full name, Address and Tax identification number of the seller along with the wording ‘Head Office’ or ‘Branch no. xxxxx
  • Full name, Address and Tax identification number (if any) of the purchaser of goods or services along with the wording ‘Head Office’ or ‘Branch no. xxxxx
  • Serial number of Tax Invoice
  • Date of issuance
  • Description, quantity, value of goods or services
  • VAT amount clearly separated from the amount of invoiced goods or services, example as follows:
    Total Before VAT: THB 10,000
    VAT: THB 700
    Grand Total: THB 10,700

Tax point

For the sale of goods, the VAT is due when the goods are delivered, regardless of when payment is made. Upon delivery, the seller typically issues a ‘Tax Invoice / Delivery Note’ and upon payment, it issues a ‘Receipt’. However, if advance payment is made before delivery, then the VAT is due upon payment receipt.

For the provision of services, the VAT is due when the customer pays, regardless of when the service is provided. Upon services rendered, the seller issues an ‘Invoice’ and upon payment, it issues a ‘Tax Invoice / Receipt’.

Calculation & Submission to the Revenue Department

VAT Payable = Output VAT – Input VAT where Output VAT refers to VAT collected from revenues subject to VAT and Input VAT refers to VAT paid through the purchase of goods or services subject to VAT.

The excess of Output VAT over Input VAT must be remitted to the Revenue Department while the excess of Input VAT over Output VAT results in a tax credit. VAT returns are filed on a monthly basis and the submission along with tax payment is due within the 15th of the following month (+8 extra days when submitted online).

Let’s  say your company issued an Invoice on 15th January for the provision of consulting services for THB 10,000 + VAT. It also paid an Invoice on 20th January for marketing services to a supplier for THB 5,000 + VAT.

Output VAT = THB 10,000 * 7% = THB 700
Input VAT = THB 5,000 * 7% = THB 350
VAT Payable = THB 350 due within 15th February


The fine for late submission is THB 300 if the VAT return is filed within 7 days from the due date and THB 500 if it is submitted later. There is also a surcharge of 1.5% of the amount of tax payable per month.
