Thai VAT 7% Calculator
Three calculation modes: split VAT from a total price, add VAT to a base price, or find base and total from a known VAT amount.
Calculation mode
When to use each mode
Total (incl. VAT) → split
You have the final invoice total and need to separate the base price and VAT amount. Common when reconciling accounts.
Base (excl. VAT) → total
You know the base price and need to add VAT before quoting a customer or issuing an invoice.
VAT amount → find base
You see only the VAT line on a document and need to back-calculate the base price and total.
VAT rate is currently 7% under the Revenue Code and annual Royal Decrees. Certain goods/services are exempt (e.g., unprocessed agricultural products, educational and medical services). Always verify with your accountant or the Thai Revenue Department.
