How it works: Withholding tax

Withholding tax is always calculated on the amount before VAT. For a 10,000 baht service plus 700 baht VAT, the payer withholds 3% of 10,000 = 300 baht, pays you 10,400 baht and gives you a withholding certificate (50 Tawi) that you can credit against your own tax.

Common rates: services and freelance work 3%, advertising 2%, transport 1%, rent 5%. Choose “amount I want to receive” to work backwards to the invoice amount.

FAQ

Is the 3% taken from the total including VAT?

No, only from the amount before VAT.

Do I get the withheld tax back?

It is credited against the tax you owe when you file your annual return; if more was withheld than you owe, you get a refund.
