South Korea’s national tax revenue is projected to reach the late 470 trillion won range, more than 60 trillion won above the 415.4 trillion won forecast issued with March’s supplementary budget. The Ministry of Finance and Economy effectively finalized the revised estimate after a tax revenue estimation committee meeting on the 22nd, with related ministries confirming the development on the 27th. Semiconductor earnings drove stronger corporate tax payments, while securities transaction tax and rural development tax receipts also far exceeded expectations. Revenue totaled 274 trillion won through July, up 41.4 trillion won from a year earlier. August interim corporate tax prepayments, particularly from Samsung Electronics and SK hynix, were higher than the government’s 40.4 trillion won assumption. Securities transaction tax receipts reached 8.2 trillion won through July, while the rural development tax totaled 13.1 trillion won. Both taxes remain key variables for the final estimate because market activity can change sharply before year-end. The revised outlook is nearly 90 trillion won above the 390.2 trillion won estimate used when the main budget was prepared, highlighting the sensitivity of government revenue to semiconductor conditions. Earlier planning for a Future Response Fund was based on at least 50 trillion won in excess revenue and a potential fund size of 212.3 trillion won, though allocation decisions remained pending.
