Finance Minister Yoo Il-ho has maintained his reluctance to raise corporate taxes, saying that the move will negatively affect investment.

Attending a meeting of the parliament's Special Committee on Budget and Accounts on Thursday, the minister said that scholars generally agree that lower corporate taxes raise investment if all other conditions are the same.

Yoo, who also serves as deputy prime minister, made the remark in response to calls to revise the tax code to ease income disparity and encourage corporate investment.

When asked about his view on an overall income tax revision, Yoo said it's necessary to review the matter. He promised to push for related discussions, stressing the need for debates and research on the issue.

Regarding whether the maximum income tax rate will be raised, the minister said the current rate of 38 percent plus residence tax equals a total of 41-point-eight percent. He said the level may not be high globally, but it is also not considered low, adding that a global comparison is necessary and avoided giving a direct answer.

Regarding when the government will submit a supplementary budget plan to the National Assembly, Yoo said that procedures aim to have the bill submitted within this month, possibly around July 25th.
