Use this page to prepare an invoice that can be printed, sent as a PDF, or attached to a client billing email for work supplied in South Korea. The invoice should identify the seller, the buyer, the goods or services, the supply date, the amount due, and the payment terms. A printed copy should match the source record, so the buyer can reconcile it without asking for missing tax or billing details.
South Korea uses VAT for taxable supplies of goods and services. For VAT purposes, the tax invoice sits inside the Value-Added Tax Act framework. A Korean VAT tax invoice must show the supplier's registration number and name or trade name, plus the registration number of the person receiving the supply. Those identifiers matter as much as the invoice total.
A Korean VAT tax invoice separates the value of supply from 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. For a service invoice, a clean line item might show consulting services, supply value of ₩1,000,000, VAT of ₩100,000, and a total payable amount of ₩1,100,000.
The invoice should also state the date of preparation. Related decree rules add transaction particulars such as item details and supply date, so a printable invoice should not collapse the transaction into one vague description. Use specific item names, quantities or service periods, unit prices where relevant, and a payment instruction that matches the contract. South Korean VAT invoice-content rules do not set one universal net-payment period.
Printing creates a readable copy, but it does not change the invoice's legal role or reporting status. 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.
The biggest printing mistake is treating the paper version as the controlling record when the business is subject to electronic tax invoice rules. A printed invoice should reproduce the electronic tax invoice details, including the business registration numbers, supply value, VAT amount, preparation date, and transaction particulars. If the invoice is only a commercial payment request, label it clearly and avoid presenting it as a VAT tax invoice unless it meets the required content.
A one-off printable invoice is enough for a small, clearly documented sale where you already know the client details, VAT treatment, supply value, and payment terms. It works best when the job has one or two line items and no need to pull hours, expenses, rates, or prior uninvoiced work from a separate time record.
A managed workflow fits recurring client work, project billing, and teams that need an audit trail from work performed to invoice issued. Everhour Reporting can organize tracked time, budgets, costs, project data, invoice status, and billable amounts with custom columns, filters, grouping, exports, and scheduled email delivery. That reporting layer helps keep the printed invoice tied to the underlying work record.

A South Korean VAT tax invoice uses business registration numbers as the core tax identifiers. It must state the supplier's registration number and name or trade name, and it must also state the registration number of the person receiving the supply. Check both numbers before printing because the buyer may need the invoice to support input-tax credit claims.
A VAT tax invoice must separately state the value of supply and the VAT amount. South Korea's standard VAT rate is 10 percent of the taxable supply value unless a zero-rate or exemption rule applies. A printed copy should preserve that split instead of showing only one gross total.
Yes, a printable copy can be kept or sent for convenience, but printing does not replace electronic issuance or transmission where those rules apply. Corporate businesses and prescribed individual businesses must issue electronic tax invoices, and issuance details generally must be transmitted to the National Tax Service by the day after issuance under decree rules.
The VAT Act requires the date of preparation on the tax invoice. A tax invoice is generally issued at the time of supply, with statutory exceptions such as consolidated monthly issuance by the 10th day of the following month where the VAT Act permits it. Keep the preparation date, supply date, and service period consistent.
South Korean VAT invoice-content rules do not set one universal net-payment period. Payment due dates are usually contract terms. Add the agreed due date, bank details, currency, and any purchase order reference needed by the buyer, then keep the tax invoice fields separate from ordinary collection language.
Everhour Reporting lets admins build reports with 45+ columns, including task, project, client, member, billable time, labor costs, profit, invoice status, and budget metrics. Teams can filter, group, export, or schedule those reports so printed invoices stay connected to the tracked work behind them.
Everhour Billing & Invoicing turns uninvoiced time and expenses into client invoices, calculates amounts from rates and billable expenses, and excludes non-billable work. Invoice data can be grouped by project, task, person, date, or another available breakdown before export to QuickBooks Online, Xero, or FreshBooks.
Connect printed invoices to the work behind them. Everhour gives teams reporting, exports, and invoice status visibility from tracked time to client billing.
