Value-added tax (VAT) is a tax levied on goods and services purchased by consumers. Businesses collect this tax and remit it to the tax authorities. If individuals or companies engage in business activities that exceed a certain threshold, they are required to file and pay this tax. Although the tax calculation and filing process can seem complex, understanding and properly executing it is essential.

VAT Filing Procedure
The VAT filing procedure occurs twice a year, on a quarterly basis. The filing periods are typically from January 1 to June 30, and from July 1 to December 31. During these periods, each business must calculate the tax payable by comparing sales and purchase amounts.
The main steps in the filing procedure are as follows:
Calculating sales and purchase amounts: Accurately calculate the sales and purchase amounts for the specified period.
Tax calculation: Subtract the purchase tax from the sales tax to calculate the tax payable.
Completing the tax return: File the VAT return via the National Tax Service’s electronic filing system, Hometax (www.hometax.go.kr
).
Payment: Remit the calculated tax to the tax authorities.
Key Points:
- Filing must be done within the deadline, as penalties apply for late filing.
- Accurate calculation of sales and purchase amounts can help avoid unnecessary tax payments.
How to Calculate VAT
VAT calculation is a critical aspect. Incorrect calculations can lead to overpayment of taxes or trigger tax audits. VAT is calculated by subtracting purchase tax from sales tax.
Example of VAT calculation:
Sales Tax: If a business sells goods worth 100,000 KRW, a 10% VAT is applied, making the sales tax 10,000 KRW.
Purchase Tax: If the business purchases raw materials worth 60,000 KRW, the purchase tax is 6,000 KRW.
Payable Tax: The business must pay the difference of 4,000 KRW, which is the sales tax minus the purchase tax.

| Item | Sales 100,000 KRW | Purchases 60,000 KRW |
|---|---|---|
| Tax Amount | 10,000 KRW | 6,000 KRW |
| Payable Tax | 4,000 KRW | |
Key Points:
The tax payable must be accurately calculated by subtracting the purchase tax from the sales tax.
Incorrect VAT calculation can cause difficulties in paying taxes.
