The debate over South Korea's Financial Investment Income Tax, or 'Geumtuse,' is back on the table just over a year and a half after it was officially abolished.
So why is this happening now? The core reason is a growing consensus that the current system, which relies solely on a transaction tax, is inadequate for encouraging long-term investment. It's simply too blunt an instrument.
There are a few key factors driving this shift. First, the abolition of the FIT in December 2024 created a policy vacuum. The government attempted to fill this gap by adjusting the transaction tax and expanding Individual Savings Accounts (ISAs), but these measures lack the sophistication to precisely reward investors based on their holding periods. This dilemma has led policymakers to reconsider a FIT-like structure specifically designed to incentivize long-term commitment.
Second, a powerful stock market rally since late 2025 has intensified the conversation. With the KOSPI index surging and major stocks like Samsung Electronics gaining over 200% between September 2025 and April 2026, the call to 'tax where there's income' has grown louder. This market boom has also increased political pressure to implement a system that favors stable, long-term growth over short-term speculative trading.
However, the government is proceeding with caution. A painful lesson was learned in the summer of 2025 from the 'major shareholder' tax controversy. An abrupt policy proposal at that time triggered market turmoil and a public outcry, forcing a swift reversal. This incident underscored the critical importance of predictability in capital market policies.
Therefore, the current discussion is not about a simple revival of the old tax. It's about a comprehensive redesign. The focus is on creating a smarter system with clear incentives, such as tax deductions that increase the longer an investment is held. The full details of this new approach are expected to be unveiled in the government's tax reform plan in the second half of 2026.
