Taiwan VAT / GUI Invoice Guide (TWD + Free PDF)

· · Reviewed by NestInvoice editorial team

Taiwan business invoices often need clear tax ID details and a VAT breakdown in TWD. Government Uniform Invoice (GUI / 統一發票) or e-invoice rules may apply — this site creates a readable PDF draft, not an official GUI issuance channel. Confirm which format your buyer and registration require. Do not treat China fapiao or Singapore GST as drop-in replacements — use the hub /tw.

What to show

Supplier tax ID, unique number, dates, customer, lines, net, VAT when charged, total in TWD. Commercial checklist: what to include on an invoice.

Keep net/VAT/gross easy to read so the client can book the document without guessing.

Rates and registration

Adjust or remove Taxes for non-standard supplies or when you are not charging VAT.

Regional structure only: Singapore GST, China fapiao, Korea VAT.

PDF vs GUI / e-invoice

A clear PDF helps the client pay. It does not replace mandatory GUI or e-invoice issuance when those rules apply. When the buyer needs the official format, treat this tool as a draft or annex.

Frequently asked questions

Is this an official GUI / e-invoice?

No. Use authorized channels when GUI or e-invoicing is mandatory. Here you get a readable client PDF draft.

Which rate should I use?

Confirm the applicable rate for your supply. Generator defaults are starters only — adjust Taxes before sending.

Same as Singapore GST or China fapiao?

No. Taiwan has its own GUI / VAT rules and TWD. Use [/tw](/tw), not only an SG or CN 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.
