Complete VAT Guide: Calculation and Filing Methods

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

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.

5. Filing and Payment

General taxpayer: Period 1 (Jan-Jun) โ†’ File/pay by Jul 25. Period 2 (Jul-Dec) โ†’ File/pay by Jan 25 next year. Simplified taxpayer: File once yearly by Jan 25. E-filing (Hometax) is convenient. Must issue tax invoices, penalties apply for non-issuance.

6. VAT Reduction Tips

โ‘  Maximize input tax deduction: Get tax invoices/card receipts for business expenses. โ‘ก Simplify proof with credit cards. โ‘ข Consider simplified taxpayer conversion (sales <80M). โ‘ฃ Check zero-rate eligible industries. โ‘ค Apply for early refund of provisional tax. โ‘ฅ Input tax deduction when purchasing business assets.

Conclusion: VAT is an important tax obligation for business owners. Avoid penalties with accurate calculation and timely filing, and reduce tax burden by maximizing input tax deductions.
