### Filing VAT Returns

**Frequency of Filing**

VAT returns in South Korea must be filed quarterly(Jan., Apr., July, Oct.). Each quarter's VAT return is due by the 25th of the month following the end of the quarter. For example, for the first quarter ending March 31, the VAT return is due by April 25.
