In the first half of 2025, minority shareholders who traded listed shares on the over-the-counter market must file and pay the capital gains tax on stock transfers for the first time starting this month.

The National Tax Service (NTS) noted on the 5th, "We will provide guidance to capital gains tax filers for the first half of 2025 by Sept. 1."

Filing subjects include ▲major shareholders who transferred listed shares ▲minority shareholders who traded listed shares in over-the-counter transactions ▲shareholders who transferred unlisted shares.

However, among shareholders who transferred unlisted shares, minority shareholders (holding less than 4% equity and with market capitalization of less than 5 billion won) trading stocks of small and medium-sized enterprises in the unlisted stock transaction market operated by the Korea Financial Investment Association (K-OTC) are excluded from the filing.

An NTS official explained, "Starting from this filing, we will collect stock transfer data between accounts from securities firms early and provide filing guidance for minority shareholders who traded listed shares over the counter and unlisted corporation shareholders for the first time."

Starting today, the NTS will dispatch mobile notifications through apps like Kakao and Naver, and for those who have difficulty receiving mobile notifications or senior taxpayers (aged 60 and over), separate guidance will be sent by mail on the 12th.
