Mirae Asset Securities said on April 27 that the cumulative balance of its domestic market return accounts (RIA) exceeded 250 billion won a month after the scheme was introduced.

The company said the RIA balance started at 14.7 billion won on the first day of the system on March 23, reached 100 billion won in the second week and hit 200 billion won before a month had passed. It then topped 260 billion won as of April 26. It said this shows the direction of government policy to move overseas assets back to South Korea is translating into action.

Samsung Electronics and SK Hynix were the most active stocks for domestic reinvestment after selling overseas shares, with the two semiconductor bellwethers ranking first and second.

RIA is a special account the government introduced for a limited period in 2026 to steer funds invested in overseas shares back into South Korea's capital market. The key benefit is a reduction in capital gains tax on overseas shares.

If investors transfer overseas shares held before Dec. 23, 2025, to an RIA account, sell them, convert the proceeds into won and reinvest for at least 1 year in domestically listed shares, domestic equity funds and ETFs, they can deduct up to 100 percent of capital gains tax.

The deduction rate is applied differently depending on the time of sale. It is 100 percent from January to May, 80 percent from June to July and 50 percent from August to December. The subscription condition is one account per person at each securities firm, and the combined deposit limit across all securities firms is 50 million won.

A Mirae Asset Securities official said, "We will further strengthen our guidance and service system so customers can easily use RIA and enjoy tax-saving benefits."
