Calculating Thailand VAT
Start from the price excluding tax
VAT is charged on the net price. At 7%, a net THB 100 becomes THB 107.00 once VAT of THB 7.00 is added.
To work backwards, divide — never subtract
Removing VAT from a gross figure means dividing by 1.0700, not subtracting 7%. Subtracting the percentage from the gross amount understates the net price, and the error grows with the rate.
Registration is threshold-based
Businesses with taxable turnover above THB 1,800,000 a year must register and charge VAT. Below it, registration is usually voluntary — worth doing when your customers can reclaim the tax.
Worked example at 7%
Adding and removing VAT at 7%
| Component | Adding to a net price | Removing from a gross price |
|---|---|---|
| Starting amount | THB 100.00 | THB 1,000.00 |
| VAT at 7% | (THB 7.00) | (THB 65.42) |
| Result | THB 107.00 | THB 934.58 |
So a net price of THB 100.00 in Thailand costs THB 107.00 once VAT is added. Working the other way, a gross price of THB 1,000.00 contains THB 65.42 of VAT, leaving THB 934.58 net.
Computed from the same 7% rate the calculator applies, so this table and the calculator cannot disagree.
