Use this page to prepare invoices for South Korean customer billing where VAT tax invoice details matter. The record needs the supplier details, buyer details, item or service description, supply value, VAT amount, and preparation date. South Korea uses VAT for taxable supplies of goods and services, so the invoice should identify VAT, not GST or sales tax.
The tax-registration identifier is the business registration number assigned under South Korean VAT registration rules. A VAT tax invoice must show the supplier's registration number and name or trade name, plus the business registration number of the person receiving the supply. Those identifiers matter because the buyer uses the tax invoice to support input-tax credit records.
Start with the commercial basics: invoice number, issue date, supplier name, buyer name, contact details, item description, quantity, unit price, currency, payment method, and payment due date. Then add the VAT tax invoice fields South Korea requires for VAT purposes: supply value, VAT amount, preparation date, and the business registration numbers for both parties.
The standard South Korean VAT rate is 10% of the taxable supply value unless a zero-rate or exemption rule applies. Keep the supply value and VAT amount separate, instead of folding tax into a single total. For example, a ₩1,000,000 taxable service line should show ₩1,000,000 as the supply value and ₩100,000 as VAT before the final amount due.
South Korean VAT tax invoices are generally issued at the time of supply. The VAT Act also permits statutory exceptions, including consolidated monthly issuance by the 10th day of the following month where the rule applies. Invoice software should let you record the actual supply date and the preparation date, since those dates answer different tax and accounting questions.
Corporate businesses and individual businesses prescribed by Presidential Decree must issue electronic tax invoices rather than paper tax invoices. After 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 manual invoice file does not replace that reporting step where the mandate applies.
A one-off invoice tool is enough when you need a clean document for a single job, a simple service line, and a contractual payment date. South Korean VAT invoice-content rules do not set one universal net-payment period, so the due date should follow the contract. Keep supporting records with the invoice, especially the work description and tax treatment.
A managed workflow matters when invoices come from many projects, staff members, rates, and billable expenses. Everhour Reporting can group and filter logged work, add invoice status and budget columns, export reports, and schedule delivery to the people who review billing. That gives finance a repeatable record before an invoice reaches the accounting system.

South Korea uses VAT for taxable supplies of goods and services. A compliant VAT tax invoice should show VAT details, not GST or sales tax. The standard VAT rate is 10% of the taxable supply value unless a zero-rate or exemption rule applies.
A South Korean VAT tax invoice must include the supplier's business registration number and name or trade name. It must also show the business registration number of the person receiving the supply. These identifiers connect the invoice to the parties registered under the VAT rules.
Yes. A VAT tax invoice must separately state the value of supply and the VAT amount. Separate lines help the buyer support input-tax credit records and help the seller keep taxable revenue, VAT collected, and total amount due from being mixed together.
No universal statement covers every seller. Corporate businesses and individual businesses prescribed by Presidential Decree must issue electronic tax invoices. After issuance, the electronic tax invoice details must be transmitted to the National Tax Service by the statutory deadline, generally the day after issuance under the decree rules.
Use the payment term in the contract or purchase order. South Korean VAT invoice-content rules do not create one universal net-payment period. Commercial overdue claims can be affected by the Commercial Act default-interest framework, but the ordinary due date belongs in the commercial agreement.
Everhour Reporting lets teams build billing reports with 45+ columns, filters, grouping, date ranges, and export formats such as CSV, Excel/XLSX, and PDF. A finance reviewer can check billable time, invoice status, budget data, and project details before preparing a South Korean VAT tax invoice.
Everhour Billing & Invoicing turns uninvoiced billable time and expenses into client invoices. The amount due comes from billable time, rates, and billable expenses, while non-billable work stays out of invoice totals. Invoices can be exported to QuickBooks Online, Xero, or FreshBooks.
Use Everhour Reporting to review billable work, invoice status, project costs, and exports before recurring billing cycles, so South Korea invoice preparation starts from organized records.
