Korean VAT Basics
General vs. Simplified Taxpayer
Individual business owners with annual revenue under KRW 80 million are classified as simplified taxpayers and use a simplified calculation based on industry value-added rates. Those above KRW 80 million are general taxpayers who deduct input tax from output tax.
Output Tax and Input Tax
Output tax is 10% of sales. Input tax is the VAT (10%) included in business expenses. Payable tax = Output tax - Input tax. When purchases exceed sales (in tax terms), you may be eligible for a refund.
Filing Periods
Korean VAT is filed twice a year: Period 1 (Jan–Jun) is due by July 25, and Period 2 (Jul–Dec) is due by January 25 of the next year.
FAQ
What are zero-rated sales?
Zero-rated sales apply to exports and overseas services at a 0% tax rate. Output tax is zero, but input tax credits still apply — so most zero-rated businesses receive a refund.
Can simplified taxpayers get a refund?
Generally, simplified taxpayers cannot receive refunds. Their input tax deduction is limited, and even if the calculated tax goes negative, it is typically not refunded.
Can I use these results for actual filing?
This calculator provides a quick estimate. Actual filing requires consideration of surcharges, tax reductions, deemed input tax credits, and more. Always consult a tax professional for your official return.
