Frequently asked questions
What is Korea's standard VAT rate?
The standard rate is generally 10%, but zero-rated, exempt, and simplified-tax transactions follow separate rules.
How do I remove VAT from a tax-inclusive price?
At a 10% rate, divide the VAT-inclusive price by 1.1 to estimate the supply value.
Is the quarterly estimate the final filing amount?
No. Actual filing depends on invoices, deductible input tax, business type, and current tax rules.
