Thailand VAT Invoice Guide (THB + Free PDF)

· · Reviewed by NestInvoice editorial team

Thai VAT invoices should identify the supplier (Tax ID) and show VAT clearly in THB. Generator defaults often start near 7% — confirm current Revenue Department treatment for your supply. Official e-Tax Invoice rules may apply separately; this generator creates a readable client PDF, not a government submission channel. Do not copy Vietnam or Singapore rates onto TH invoices — use the hub /th.

What a Thai VAT invoice usually shows

Supplier Tax ID, unique number, dates, customer, lines, net, VAT, total in THB — see what to include.

Keep net/VAT/gross easy to read so finance teams can post the bill without guessing.

Rates and registration

Do not leave 7% on a non-taxable or differently rated supply. Clear Taxes if you are not VAT-registered.

Neighbours for layout only: Vietnam VAT, Singapore GST, Indonesia PPN.

PDF vs e-Tax Invoice

A clear PDF helps the client pay. It does not replace mandatory e-Tax Invoice channels when the Revenue Department requires them. When the buyer needs an official structured document, treat this tool as a draft or annex.

Frequently asked questions

Is VAT always 7%?

7% is a common standard-rate starter in generators. Confirm current Revenue Department treatment (or exemption) before locking the PDF.

Is this e-Tax Invoice software?

No. Use authorized channels when mandatory. This tool creates a readable PDF draft or annex.

Same as Vietnam or Singapore?

No. Thailand has its own rates and THB. Use [/th](/th), not only a VN or SG generator.

Where do I put Tax ID?

Under From. Add the client Tax ID when required.

Quote or invoice?

A quote is a proposal. The invoice is the payment request — keep them separate in your records.
