Use this page to prepare a downloadable invoice for taxable work supplied in South Korea. The finished document should identify the seller and buyer, describe the supplied goods or services, show the chargeable amount, and separate VAT from the supply value. For VAT purposes, South Korea treats these documents as tax invoices under the Value-Added Tax Act.
A clean invoice also supports collection. Add the invoice number, issue date, payment due date, bank details, and contact information so the buyer knows exactly what to approve and pay. South Korean VAT invoice-content rules do not set a universal net-payment period, so ordinary due dates come from the contract or commercial terms agreed with the buyer.
South Korea uses VAT for taxable supplies of goods and services, so the invoice should label the tax as VAT. The standard South Korean VAT rate is 10% of the taxable supply value unless a zero-rate or exemption rule applies. A VAT tax invoice must separately state the value of supply and the VAT amount.
The tax-registration identifier is the business registration number assigned under VAT registration rules. A South Korean VAT tax invoice must state the supplier's registration number and name or trade name, plus the registration number of the person receiving the supply. The VAT Act also requires the date of preparation, and decree rules add transaction particulars such as item details and supply date.
A downloaded invoice is useful only after the timing and format fit the transaction. 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. Match the preparation date to the tax point used for the sale.
Electronic tax invoices deserve a separate check before download. Corporate businesses and individual businesses prescribed by Presidential Decree must issue electronic tax invoices rather than paper tax invoices. After issuance, 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.
A one-off downloadable invoice is enough for a single project, a short engagement, or a buyer that only needs a PDF and the required VAT details. It works best when the amount is already approved, the tax treatment is clear, and the seller only needs to create a clean record for delivery and payment.
A managed workflow fits recurring client work, multiple people, billable expenses, or projects where tracked time becomes the invoice source. Everhour Billing & Invoicing converts tracked billable time and expenses into invoices, calculates amounts from rates while excluding non-billable tasks, and can export invoices to QuickBooks Online, Xero, or FreshBooks with status sync back to Everhour.

Use the business registration number. A South Korean VAT tax invoice must state the supplier's registration number and name or trade name, and the registration number of the person receiving the supply. This identifier is the core VAT registration detail for both parties and should match the buyer and seller records used for the transaction.
Show the supply value and VAT amount separately. South Korea's VAT tax invoice rules require both figures, and that separation helps the buyer support input-tax credit claims. For a standard taxable supply, the VAT rate is 10% of the taxable supply value unless a zero-rate or exemption rule applies.
South Korean VAT invoice-content rules do not set a universal net-payment period. The payment due date is a contract term, so the invoice should reflect the agreed terms, such as payment on receipt, a specific due date, or a negotiated net period. Commercial overdue claims may be affected by the Commercial Act default-interest framework.
A PDF alone does not satisfy the electronic tax invoice workflow for businesses covered by the mandate. Corporate businesses and individual businesses prescribed by Presidential Decree must issue electronic tax invoices rather than paper tax invoices, and issuance details must be transmitted to the National Tax Service by the statutory deadline, generally the day after issuance.
Check the date of preparation and the supply date details. The VAT Act requires the tax invoice to include the date of preparation, and related decree rules add transaction particulars such as item details and supply date. A tax invoice is generally issued when goods or services are supplied, subject to permitted statutory exceptions.
Everhour Billing & Invoicing converts tracked billable time and expenses into client invoices, calculates invoice amounts from rates, and excludes non-billable work.
