A must-know for business owners! Everything about VAT from calculation to filing and refunds.

01

1. What is VAT?

Value Added Tax (VAT) is a tax imposed on added value at each transaction stage of goods and services. Rate is 10%, ultimately borne by consumers. Business owners pay the difference between output tax and input tax. Zero-rate (0%) and exemption items also exist.

2. VAT Calculation Method

VAT = Supply value ร— 10%. Example: Supply 1M KRW โ†’ VAT 100K KRW โ†’ Total 1.1M KRW. Reverse: Total 1.1M รท 1.1 = Supply 1M, VAT 100K. Tax payable = Output tax (collected) - Input tax (paid). If input tax is larger, receive refund.

3. General vs Simplified Taxpayer

General taxpayer: Annual sales โ‰ฅ80M KRW. 10% rate, file twice yearly (Jan/Jul). Simplified taxpayer: Annual sales <80M KRW. Industry-specific value-added rate (0.5-30%), file once yearly (Jan). Simplified has lower tax burden but limited input tax deduction. Consider converting to general if planning growth.

4. Zero-rate and Exemption

Zero-rate (0%): Exports, international transport/services. 0% rate but input tax deductible (refund possible). Exemption: Basic agricultural products, medical/education services, housing rental. VAT exempt but no input tax deduction. Zero-rate benefits businesses, exemption benefits consumers.
