    FAQ about VAT and withholding tax

    Understand the basics and talking to your accountant gets easier

    Is withholding tax calculated before or after VAT?

    Before VAT. For example, a 10,000 THB service fee plus 700 THB VAT totals 10,700 THB. 3% withholding is 300 THB, so the actual transfer is 10,400 THB.

    Do I withhold tax when paying for Facebook / Google ads?

    Generally no, because the provider is an overseas company that charges your card directly. But if your company is VAT-registered and has entered its tax ID in the ad account, receipts won't include Thai VAT and you must file P.P.36 to remit the 7% VAT yourself. If you pay through a Thai agency, withhold according to the service type on the invoice.

    What do I need to do after withholding tax?

    The payer must issue a withholding tax certificate (50 Tawi) to the payee and file the tax return (P.N.D.3 for individual payees or P.N.D.53 for juristic persons) by the 7th of the following month, or by the 15th if filing online.

    If we agreed on a "net received" price, how should I invoice?

    Choose the "Net amount the payee receives" mode and enter the agreed amount. We'll work backwards to the pre-VAT price to put on the invoice, so after withholding the payee receives exactly the agreed amount.
