Use this page to create a South Korea invoice that separates commercial billing details from VAT tax invoice requirements. Taxable supplies in South Korea use VAT, not GST or United States sales tax, and the standard VAT rate is 10% of the taxable supply value unless a zero-rate or exemption rule applies.
A practical invoice should show who supplied the work, who received it, what was supplied, the supply value, the VAT amount, and the date of preparation. Add payment terms from the contract, since South Korean VAT invoice-content rules do not create one universal net-payment period for ordinary invoices.
A South Korean VAT tax invoice must include the supplier's registration number and name or trade name. It also needs the business registration number of the person receiving the supply. That registration number is the core tax identifier assigned under VAT registration rules, so it belongs near the party details rather than buried in notes.
The money fields need the value of supply and the VAT amount shown separately. Item details and supply date support the transaction record, while the date of preparation satisfies the VAT Act invoice requirement. A clean invoice keeps these fields distinct from late fees, discounts, deposits, and other contract items.
Corporate businesses and individual businesses prescribed by Presidential Decree must issue electronic tax invoices instead of 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.
Issue timing matters because a tax invoice is generally issued when goods or services are supplied. The VAT Act allows statutory exceptions, including consolidated monthly issuance by the 10th day of the following month in permitted cases. Match invoice timing to the supply event or the allowed consolidated period before sending the document.
A free invoice tool is enough for a single client bill when you already know the taxable supply value, VAT treatment, buyer registration number, and payment terms. It also works when you need a clean draft before entering the final electronic tax invoice in the required reporting process.
A managed workflow becomes necessary when multiple people log time, some tasks are non-billable, or rates vary by project. Everhour supports project billing status, task-level non-billable controls, custom task rates, member-rate exceptions, and admin reports for billable time, non-billable time, billable amount, and cost.

A South Korea tax invoice uses VAT. Taxable supplies of goods and services fall under the Value-Added Tax Act, and the standard VAT rate is 10% of the taxable supply value unless a zero-rate or exemption rule applies. Do not label the tax as GST or United States sales tax on a Korean VAT tax invoice.
The invoice should show the supplier's business registration number and name or trade name, plus the business registration number of the person receiving the supply. That identifier supports VAT registration and input-tax credit records, so confirm the buyer's registered details before issuing the tax invoice.
The VAT amount should appear separately from the value of supply. That separation lets the buyer support input-tax credit claims and keeps the invoice aligned with South Korean VAT tax invoice fields. A single total without a clear VAT line creates avoidable review work for both parties.
Corporate businesses and individual businesses prescribed by Presidential Decree must issue electronic tax invoices. Issuance details must be transmitted to the National Tax Service by the statutory deadline, generally the day after issuance under the decree rules. Businesses outside that mandate still need accurate invoice records.
The contract usually sets the payment due date. South Korean VAT invoice-content rules do not impose one universal net-payment period for ordinary invoices. Commercial overdue claims can be affected by the Commercial Act default-interest framework, so keep the due date and late-payment terms clear in the agreement and invoice.
Everhour lets admins set project billing status, mark specific tasks non-billable, use custom task rates, and set member-rate exceptions. Reports can show billable time, non-billable time, billable amount, and cost, so invoice preparation starts from a cleaner billing record.
Everhour Billing & Invoicing can turn tracked billable time and expenses into client invoices. Invoice line items can be grouped by project, task, person, date, or another available breakdown, which helps match the invoice structure to the client's billing review process.
Track approved billable work before invoice time, separate non-billable tasks, and use Everhour reports to turn project activity into clearer client billing.
