-
① In Korea, the VAT rate is 10%. The VAT is generated by adding 10% of the supply price and collecting it from the purchaser in the form of transaction tax when a supplier provides goods or services.
-
② The supplier collects value-added tax from the purchaser during a certain period (taxation period) and pays it to the tax authority (tax office). During the same taxation period, the supplier calculates the value-added amount to be paid by deducting the input tax paid when purchasing from the sales tax amount.
VAT to be paid = Sales supply price x 10% - Input tax paid

3. Withholding Tax
(1) Withholding tax is applicable to the followings:
1) salary of executives and employees;
2) interest income and dividend income;
3) royalty.
(2) Monthly withholding for invested corporation (company) employees' salaries
When paying monthly salaries to the employees of the invested corporation, the business operator must withhold income tax on the monthly salary received by the employee and pay it to the relevant tax office by the 10th of the following month. (Withholding tax on employee salaries)"
In this case, the company must prepare a labor contract when hiring an employee and calculate the monthly salary according to the labor contract and deduct the withholding tax amount before paying.
(Examples of deductible amounts: income tax, four major insurances (health insurance, national pension, employment insurance, occupational health and safety insurance)
(3) Withholding tax on interest and dividend
When an invested corporation provides interest or dividend, it shall deduct the withholding tax from the interest and dividend to be paid and pay the withholding tax to the relevant tax office by the 10th day of the following month. In particular, in the case of interest or dividend to be paid abroad, since the withholding tax rate varies depending on the tax treaty, you need to check accurately and pay after deducting the withholding tax. (The same 15.4% applies in Korea, but in the case of paying to overseas countries, the tax treaty shall be checked in advance.)
(4) Withholding tax on royalties
Often, foreign-invested companies are required to pay royalty abroad, to which limited tax rate is applied according to tax treaty, so that the withholding tax rate varies depending on the country it needs to be paid to. Therefore, you need to check the withholding tax rate of the counterpart country before deducting the tax amount and paying the royalty.
