When Does a Foreign Business Need to Register for VAT in South Korea? Key Triggers
Foreign businesses must register for VAT in South Korea under several scenarios, even without a physical presence. The key triggers for VAT registration in South Korea include:
- Electronic Services: Foreign businesses providing electronic services like gaming, cloud computing, and advertising to Korean consumers must register for VAT.
- Local Inventory or Warehouse: If a foreign business maintains inventory or a warehouse in South Korea, VAT registration is required.

Note: For more detailed information on the process, refer to the VAT registration guide provided by the South Korean government to ensure compliance.
Registration Thresholds & Nexus Tests
In South Korea, there is a nil threshold for VAT registration, meaning that registration is always mandatory for non-resident sellers who provide taxable supplies to consumers in the country, regardless of their turnover or transaction volume. The following are a few other details to be noted:
- Digital service providers: Non-resident businesses providing digital products and electronic services to consumers in South Korea must register for VAT immediately upon starting their operations. There is no registration threshold.
- Low-value imports: Businesses engaged in the importation of goods into South Korea must also register for VAT, regardless of the transaction amount.
Thus, non-resident sellers of any kind (including digital services and those involved in low-value imports) must register for VAT as soon as they begin operations in the country.

While looking at VAT registration in South Korea, it is important to understand the format of the VAT ID number. The format of the South Korea VAT ID number is as follows:
- Format: XXX-XX-XXXXXX

Non-resident businesses do not always need to appoint a local tax agent or fiscal representative for VAT registration in South Korea. However, they may choose to do so for ease of compliance. If appointed, the representative may assume joint liability for VAT obligations. Some jurisdictions may require a bank guarantee or bond to secure tax payments, though this varies by country.
