Frequently asked questions
How is 7% VAT extracted from a total price?
Pre-VAT amount = total price × 100 ÷ 107, rounded to the satang. VAT = total price − pre-VAT amount. For example, a total of 107 baht splits into 100 baht before VAT and 7 baht VAT.
Why does VAT sometimes differ by 1 satang between extracting and adding?
It comes from rounding satang. When extracting VAT, the tool rounds the pre-VAT amount first and takes VAT as the difference, so that pre-VAT amount + VAT equals the total you entered exactly.
What is the current VAT rate?
The commonly applied rate is 7% (reduced from the statutory 10% by Royal Decree). If the rate changes, you can edit the VAT rate field in the tool yourself.
