What is the VAT rate in Thailand?

The standard VAT rate applied in Thailand is 7%. The statutory rate is 10%, but it has been reduced to 7% by royal decree since 1999, with the reduction renewed periodically.

Why is the Thai VAT rate sometimes quoted as 10%?

The Revenue Code sets the base VAT rate at 10%, but a long-standing royal decree caps it at 7% (which includes local taxes). Businesses charge and report 7% in practice.

How do I remove VAT from a gross Thai price?

Divide the gross by 1.07. The result is the net price, and the difference between the gross and the net is the 7% VAT contained in the price.

Who must register for VAT in Thailand?

Businesses with annual revenue over 1.8 million baht must register for VAT with the Revenue Department. Once registered, they charge 7% VAT and issue full tax invoices.

Thailand VAT Calculator

Thailand applies VAT at a standard rate of 7%. The statutory rate in the Revenue Code is 10%, but it has been reduced to 7% by royal decree since 1999 and renewed periodically. This calculator adds 7% VAT to a net price or extracts the VAT inside a gross price, giving the net / VAT / gross breakdown for Thai tax invoices.

How it works

Choose a direction:

Add VAT: gross = net × 1.07. The VAT is net × 0.07.
Remove VAT: net = gross ÷ 1.07. The included VAT is gross − net.

The 7% figure already bundles the relevant local tax, so it is the rate that appears on Thai tax invoices. There is no general reduced rate below 7% for standard supplies; exports are zero-rated separately.

Example

Add 7% VAT to a ฿1,000 net price:

VAT = 1,000 × 0.07 = ฿70.00
Gross = ฿1,070.00

To remove 7% VAT from a ฿1,070 gross price: 1,070 ÷ 1.07 = ฿1,000.00 net, with ฿70.00 VAT included.

Notes

Businesses with annual revenue above 1.8 million baht must register for VAT with the Revenue Department and issue full tax invoices. For guidance only — not tax advice. The tool runs entirely in your browser; no amounts or personal data are transmitted.
