Invoice drafting checklist for South Korea

These are practical prompts for preparing a draft, not a declaration that every field is legally mandatory in every South Korea transaction. Buyer type, registration, value, supply and document type can change the required fields.

Seller identity
Check the legal or trading name, address and identifiers relevant to the seller.
Buyer identity
Check which buyer name, address and tax identifiers the transaction requires.
Document reference
Use an identifiable invoice number or other reference appropriate to the document type.
Relevant dates
Record the issue, supply and payment dates that apply to the transaction.
Goods or services
Describe each line and check whether quantity, unit, classification or supply location is needed.
Tax treatment
Record the applicable tax basis, rate, amount, exemption or reverse-charge note after verifying it.
Amounts and currency
Check line amounts, adjustments, net, tax and payable totals and identify the currency.
Payment and delivery details
Add the agreed payment instructions and confirm whether a structured format or delivery channel is required.

What VAT rate should I use in South Korea?

The stored South Korea profile lists 10% as a reference standard VAT rate. It is not a transaction-level calculation; verify the evidence date, category, place of supply and any regional rules before using it.

How do I check e-invoicing in South Korea?

FreeBillGen has an e-invoicing research record for South Korea. Verify its buyer scope, thresholds, dates, format and delivery channel against the cited evidence; a generic UBL or CII export is not a validated national profile.
