South Korea VAT Invoice Guide (KRW + Free PDF)

· · Reviewed by NestInvoice editorial team

Korean business invoices often need clear supplier registration details (사업자등록번호) and a VAT breakdown in KRW. Official e-tax invoice rules may apply — this site helps with a readable PDF draft, not the NTS portal. Confirm the applicable rate and whether a mandated electronic format is required. Do not copy Japan consumption-tax defaults onto KR invoices — use the hub /kr.

What to show on a Korea VAT-style PDF

Supplier registration details, unique number, dates, customer, description, net, VAT when charged, total in KRW. Commercial spine: what to include on an invoice.

Keep net/VAT/gross easy to read so the client’s accounts team can post the document without guessing.

Rates and registration

Adjust or remove Taxes if the supply is not standard-rated or you are not charging VAT.

Regional structure only — not rates to copy: Japan consumption tax, Taiwan VAT / GUI.

PDF vs NTS e-tax invoice

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

Frequently asked questions

Is this an official e-tax invoice?

No. Use authorized e-tax invoice channels when required. Here you get a readable client PDF draft or attachment.

Which VAT rate should I use?

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

Same as Japan or Taiwan?

No. Korea has its own rules and KRW. Use [/kr](/kr), not only a JP or TW generator.

Where do I put the business registration number?

Under From in the tax ID field when you show it on client PDFs. Add the buyer ID when required.

Quote or invoice?

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