This article outlines how to claim a South Korea VAT refund, including eligibility, documentation, and filing steps, so your business can stay compliant with local regulations and improve cash flow management.
Key Highlights
- Learn who is eligible to claim a VAT refund in South Korea and the documentation required for compliance.
- Understand when and how to apply for the refund to optimize your tax recovery timeline.
- Identify which expenses qualify or don’t qualify for reimbursement under Korean VAT rules.
- Follow a clear step-by-step process designed for both domestic and overseas entities, referencing regional standards like the South Korea VAT refund process.
Understanding VAT in South Korea
South Korea imposes a value-added tax (VAT) on most goods and services at a standard rate of 10%. Unlike many other VAT systems, South Korea does not apply reduced rates, though certain transactions qualify for a 0% (zero-rated) rate. These include exports and related transport services, international finance and insurance, services rendered overseas, and select business support activities.
Registered entities can generally offset the VAT they pay on business purchases (input tax) against the VAT they collect on sales (output tax). When input tax exceeds output tax, businesses may claim a VAT tax refund through periodic filings to the National Tax Service (NTS).
For foreign or cross-border businesses, understanding eligibility and documentation is key to securing a South Korea VAT refund efficiently.
Who Can Claim a VAT Refund?
Wondering “how does VAT refund work in South Korea?” Businesses that pay VAT in South Korea may be eligible to recover these costs depending on their registration status and business activities.
- Domestic companies that are VAT-registered can generally reclaim VAT paid on purchases related to taxable transactions. There is no annual registration threshold in South Korea, and registration is required for all entities making taxable supplies to local consumers.
- To register, a business must maintain a physical office or branch in the country, though digital service providers are exempt from this requirement. Once registered, companies receive a VAT number that allows them to claim refunds through regular filings.
- Non-resident businesses may also qualify for a South Korea tax refund on VAT if they are not established or VAT-registered locally and do not make taxable supplies within the country. Refunds are typically available only when the applicant’s home country offers reciprocal treatment to South Korean entities.
- Exporters and cross-border service providers engaged in zero-rated activities, such as transport, insurance, or overseas business support, are likewise eligible for a South Korea VAT refund.
By understanding these eligibility rules, both domestic and foreign businesses can better manage their compliance obligations and maximize their VAT recovery opportunities in South Korea.
When Can Businesses Claim a VAT Refund?
For registered entities seeking a VAT refund in South Korea, timing and filing discipline are key. A refund may typically be claimed at the time of filing the VAT return, although the period for claiming it can vary depending on the business activity.
- Businesses typically file VAT returns quarterly, with deadlines on the 25th of the month following the end of the quarter (for example: April 25, July 25, October 25, and January 25 of the following year) under the regular scheme.
- For foreign companies not registered for VAT locally (but eligible under reciprocity), the claim must often be submitted by June 30 of the year following the year in which the expenses were incurred.
It’s important to note that late filings or corrections (“re-assessments”) must follow NTS procedures and may affect refund eligibility. Understanding the filing schedule and claim windows ensures a smooth VAT refund process in South Korea.
What Can You Claim?
Businesses operating in South Korea can recover VAT paid on goods and services that directly support taxable activities. Understanding which expenses qualify helps ensure accurate refund claims and smoother processing.
For domestic businesses, refundable expenses may include:
- Office rent, utilities, and maintenance costs
- Equipment and machinery purchases
- Business travel and accommodation
- Imports and customs-related charges
- Exhibition or trade fair participation fees
For overseas claimants, eligible expenses often cover:
- Invoices for services from South Korean suppliers
- Conference and event participation costs
- Local marketing and advertising expenditures
- Hotel stays, local transport, and professional services
Personal or non-business-related expenses, such as entertainment or personal travel, are non-refundable.
Maintaining valid tax invoices and proof of payment is essential for a seamless South Korea VAT refund application through the NTS.
What Expenses Are NOT Eligible for a VAT Refund in South Korea?/What’s Not Covered?
Not all expenses qualify for a VAT refund in South Korea. Certain goods and services are either exempt from VAT or subject to a zero rate, making them ineligible for recovery.
Exempt or zero-rated items include:
- Exports and associated transport services are taxed at 0% to maintain competitiveness in international trade.
- Financial and insurance services, including banking fees and insurance premiums.
- Medical services are provided within Korea, as well as some agricultural goods.
- Books and educational materials are often exempt from VAT.
- Services rendered overseas, including consultancy or support services performed outside South Korea.
- Select business support services that fall under specific zero-rated categories.
Businesses should carefully review these exclusions before filing a refund claim. Attempting to reclaim VAT on non-eligible items may result in delays, penalties, or rejection by the NTS. Maintaining clear records and separating eligible from ineligible expenses ensures a smooth refund process and accurate compliance.
Are Non-South Korea Businesses Eligible for a VAT Refund?
Foreign companies that pay Korean VAT on local goods or services may still be eligible to recover those costs. Understanding how to obtain a VAT tax refund as a non-South Korean business begins with the principle of reciprocity: refunds are granted only if the company’s home country allows Korean businesses to claim similar VAT refunds.
Application Process and Deadlines:
- Minimum refundable amount: KRW 300,000
- Filing deadline: June 30 of the year following the expense period
- Refunds are typically paid within six months of application
Required Documentation
- Official NTS VAT recovery form (in Korean)
- Business license (in English or Korean)
- Original tax invoices or credit-card slips showing VAT
- Detailed tax invoice list and proof of business activity
- Power of attorney if filing through an agent
By preparing complete documentation and adhering to these rules, foreign entities can efficiently secure their South Korea VAT refund.

Reclaiming VAT in South Korea is a straightforward process if your business maintains accurate records and files within the required deadlines. Here’s a clear breakdown of how to claim a VAT refund online in South Korea through the NTS portal:

Reclaiming VAT for Overseas Businesses
South Korea offers VAT refund reciprocity to several countries, including major trading partners such as the United States, the United Kingdom, Germany, France, and Japan, as well as other VAT-implementing nations. Foreign businesses that have incurred VAT expenses in South Korea can apply for a refund by following a structured process.
Here’s a simplified breakdown of how to get a VAT tax refund in South Korea as a non-resident company:
- Check eligibility and deadline: The minimum refundable VAT amount is KRW 300,000. Applications must be submitted by June 30 of the year following the one in which the expenses occurred.
- Prepare valid documentation: Gather tax invoices or credit card sales slips that clearly show the VAT amount. These serve as proof of the VAT paid in South Korea.
- Complete the official refund form: Fill out the VAT recovery application form (available from the NTS, in Korean). It must be signed or stamped by the company’s authorized representative and accompanied by a copy of your business license.
- Attach supporting evidence: Include a detailed tax invoice list, all original receipts, and a questionnaire explaining how the expenses relate to your business activities in Korea.
- Provide a power of attorney: If a local agent or service provider is handling your application, a power of attorney must be attached.
Once submitted, the South Korea VAT refund is typically processed within six months, with most payments issued by December. Keeping documentation organized and accurate ensures a faster, smoother refund experience.
