Value-added tax (VAT) is a fundamental aspect of business in South Korea. Whether you're a domestic company or a foreign business navigating South Korea's tax regulations, understanding the nuances of VAT compliance, deductions, and exemptions is crucial for effective financial planning.
This blog will break down South Korea’s VAT system, focusing on what input VAT can and cannot be deducted.
Introduction to VAT in South Korea

South Korea introduced VAT in 1977 as an indirect tax system to streamline its tax process and replace eight older indirect taxes. The system is similar to the European Union’s VAT model and is managed by the National Tax Service (NTS). VAT is charged at every stage of the supply chain, with businesses collecting VAT on their sales and reclaiming VAT paid on their purchases.
South Korean VAT Rates
South Korea uses a standard VAT rate of 10%, applicable to most taxable goods and services. While there are no reduced VAT rates like in some other countries, certain goods and services are zero-rated or exempt from VAT:
Standard Rate (10%): Most goods and services sold domestically.
Zero Rate (0%): Exports, related transport services, overseas services, financial and insurance services, and business support services.
Exemptions: Medical services, agricultural products, books, educational, and cultural services.
VAT Registration Requirements in South Korea
Any business making taxable supplies in South Korea must register for VAT, regardless of its size. However, they need to have a physical location in South Korea to get registered. In fact, foreign companies providing digital or electronic services in South Korea (e.g., streaming or software) must register for VAT, even without a physical presence.
Once the VAT application is approved, businesses are assigned a VAT registration number, making them eligible to collect and remit VAT.
South Korean VAT Compliance
VAT Returns
Registered businesses must submit periodic VAT returns. The reporting structure includes:
Return Periods:
January 1 – June 30
July 1 – December 31
Preliminary Returns: Filed at the end of the first and third calendar quarters.
Deadline: Returns must be submitted within 25 days after the end of the return period.
Tax Credits: If input VAT exceeds output VAT, businesses can claim a refund, typically processed within 30 days.
Invoice Requirements
Invoices must include:
The business name and address.
A valid VAT registration number.
The VAT rate is applied to each item.
A description of the goods or services.
An invoice sequencing number.
Tax-Deductible Input VAT
Input VAT is the Value-Added Tax (VAT) a business pays on goods or services it buys for its operations, such as materials, rent, or utilities.
For this VAT to be deductible (i.e., claimed as a refund or offset against the VAT the business charges customers), two conditions must be met:
Proper Documentation: Businesses must maintain valid tax invoices, credit card receipts, or cash receipts for their expenses.
Business Relevance: Expenses must be directly tied to taxable business activities.
Examples of deductible input VAT include:
VAT on raw materials or equipment purchases used in production.
VAT on office rent or utilities.
VAT on advertising costs incurred domestically.
Non-Deductible Input VAT
Despite having proper documentation, certain expenses are not eligible for VAT deductions under South Korea’s regulations. In other words, Non-Deductible Input VAT refers to the Value-Added Tax (VAT) that a business cannot claim back as a deduction. This usually applies to expenses that are not directly related to taxable business activities, such as entertainment costs, tax-exempt items (e.g., medical services, books), or expenses without proper VAT invoices.
These include:
1. Tax-Exempt Items
Expenses related to tax-exempt goods or services cannot be deducted. Examples include:
Medical expenses
Books
Land purchases
Agricultural, livestock, and marine products
Educational services
Financial services like insurance and loans
2. Entertainment Expenses
Any expenses categorized as entertainment for policy reasons are non-deductible.
3. Industries Without VAT Invoices
Certain industries are exempt from issuing VAT invoices, making related expenses non-deductible:
Barbershops and beauty salons
Taxis and buses
Baths and saunas
Admission tickets for events
4. Vehicle Purchase and Maintenance
VAT on vehicles (purchase or maintenance) is non-deductible unless the vehicle qualifies as a statutory vehicle, such as a van with nine or more seats.
5. Overseas Transactions
Expenses incurred abroad (e.g., advertising on Google or Facebook) do not include South Korean VAT and are therefore non-deductible.
VAT Recovery for Foreign Businesses
Foreign companies that incur VAT on local expenses in South Korea can claim a refund under certain conditions:
The refundable VAT must exceed KRW 300,000 (approximately 207.11 USD).
Refunds are typically allowed if there are reciprocity agreements between South Korea and the foreign company’s home country.
Best Practices for VAT Compliance

To minimize risks and ensure compliance, businesses should adopt the following practices:
Maintain Accurate Records: Keep detailed and organized records of all transactions, including invoices and receipts.
Timely Filing and Payment: Meet all deadlines for VAT returns and payments to avoid penalties.
Conduct Regular Audits: Periodically review transactions to ensure compliance with VAT regulations and identify discrepancies early.
Use Professional Support: Engage tax advisors or consultants familiar with South Korean VAT laws to manage compliance effectively.
Conclusion
South Korea’s VAT system is comprehensive and well-structured, ensuring transparency and compliance. While the 10% standard VAT rate applies to most goods and services, exemptions, zero-rating, and non-deductible expenses add complexity.
For businesses, understanding VAT regulations is critical to avoid financial pitfalls, optimize tax credits, and ensure compliance with the National Tax Service (NTS).
