Your immediate job is to create a tax invoice that a Korean business customer can read, book, and match to the supply. South Korea uses VAT for taxable supplies of goods and services, so the tax line should identify VAT, not GST or American sales tax. The invoice also needs enough party, date, item, and amount detail to support the buyer's records.
For a South Korean VAT tax invoice, the business registration number is the core tax identifier. The invoice must state the supplier's registration number and name or trade name, plus the registration number of the person receiving the supply. Treat those numbers as required invoice data, not optional customer notes, because a missing registration number can break the document's tax purpose.
A South Korean VAT tax invoice must separately state the value of supply and the VAT amount. The standard South Korean VAT rate is 10 percent of the taxable supply value unless a zero-rate or exemption rule applies. A clean layout shows the taxable supply value, the VAT amount, and the total payable as separate lines so the buyer can support input-tax credit claims.
The VAT Act requires the date of preparation. Related decree rules add transaction particulars such as item details and supply date. For services, a practical line item can read: "Project implementation services, supply date June 30, 2026, supply value ₩2,000,000, VAT ₩200,000." Add the payment due date from the contract, because South Korean VAT invoice-content rules do not set a universal net-payment period.
South Korea has an electronic tax invoice regime for corporations and individual businesses prescribed by Presidential Decree. Those businesses must issue electronic tax invoices rather than paper tax invoices. A paper-style PDF can be useful for internal review or client communication, but it does not replace the statutory electronic issuance workflow when the mandate applies to the supplier.
Issuance timing also matters. A tax invoice is generally issued when the goods or services are supplied, with statutory exceptions such as consolidated monthly issuance by the 10th day of the following month where the VAT Act permits it. When an electronic tax invoice is issued, its issuance details must be transmitted to the National Tax Service by the statutory deadline, generally the day after issuance under the decree rules.
A free invoice tool is enough when you need one Korean VAT invoice, already know the buyer's business registration number, and can enter the supply value, 10 percent VAT amount, preparation date, and payment term manually. It also fits occasional work where each invoice is reviewed outside a billing system before electronic tax invoice issuance, if that issuance workflow applies.
A managed workflow fits recurring client work, multiple projects, billable expenses, and time-based services. Everhour Billing & Invoicing converts tracked billable time and expenses into invoices, calculates invoice amounts from rates while excluding non-billable tasks, and supports client defaults such as contacts, taxes, discounts, and payment terms. That system reduces re-keying before final tax review and accounting handoff.

Yes. South Korea uses value-added tax for taxable supplies of goods and services, so a compliant tax invoice identifies VAT rather than GST or American sales tax. The standard South Korean VAT rate is 10 percent of the taxable supply value unless a zero-rate or exemption rule applies.
A South Korean VAT tax invoice must show the supplier's business registration number and name or trade name. It must also show the registration number of the person receiving the supply. The business registration number is the tax-registration identifier assigned under VAT registration rules.
No. A VAT tax invoice must separately state the value of supply and the VAT amount. Keep those figures apart from the final total so the buyer can match the taxable amount, the 10 percent VAT charge where applicable, and the amount payable.
Corporate businesses and individual businesses prescribed by Presidential Decree must issue electronic tax invoices rather than paper tax invoices. Once an electronic tax invoice is issued, issuance details must be transmitted to the National Tax Service by the statutory deadline, generally the day after issuance under the decree rules.
A South Korean VAT tax invoice must include the date of preparation. Related decree rules add transaction particulars such as item details and supply date.
