How do you calculate 7% VAT and Thai withholding tax correctly?
Calculate VAT (7%) both ways: add VAT to a pre-tax price to see the total to charge, or extract VAT from a VAT-inclusive total to see the net price and the tax portion. Adjust the rate if you need a different one.
It's handy for shops, freelancers issuing receipts, and checking whether a listed price already includes VAT. Extracting VAT is simple — divide the gross by 1.07. Need proportions or discounts too? Try the percentage calculator, and see the income tax calculator to plan your taxes.
For example, quoting a client ฿25,000 before tax means invoicing ฿26,750 including VAT (฿1,750 of tax). Reading a ฿535 restaurant bill the other way: ฿500 is the food, ฿35 is VAT. In Thailand, businesses with revenue over ฿1.8 million a year must register for VAT, and a proper tax invoice has to show the net amount, the VAT and the total separately — which is exactly the breakdown this tool gives you. Everything is calculated in your browser, so no figures leave your device.
