The government's move to overhaul the existing Individual Savings Account (ISA) system while creating a new "productive finance" ISA is seen as reflecting a policy intent to concentrate tax benefits on domestic investment, steering individual investors' funds into Korea's capital market. However, critics argue that the structure, which requires selecting only domestic assets to receive tax-saving benefits, has narrowed investors' options for asset allocation.
According to the financial investment industry on the 4th, analysts say the 2026 tax reform has changed the very nature of the ISA. The existing ISA had strong characteristics of a general-purpose asset management account that allowed investors to enjoy tax-saving effects while investing in a wide range of domestic and overseas financial products. In contrast, the newly created productive finance ISA has taken on a stronger character as a policy account that concentrates tax benefits on domestic assets such as domestically listed stocks and domestic equity funds.
Investors' attention also focused on the fact that tax benefits for overseas investment products have effectively disappeared. Under the existing ISA, investors could receive tax benefits while investing in domestically listed overseas exchange-traded funds (ETFs) or overseas asset funds, but the new ISA requires investment in domestic assets. Given that the approach of holding domestically listed ETFs tracking overseas indices such as the Standard & Poor's (S&P) 500 or Nasdaq 100 in an ISA for long-term investment had established itself as a representative tax-saving strategy among individual investors, adjustments to investment strategies have become unavoidable. In online investment communities, reactions continued, such as "If domestically listed overseas ETFs are excluded, there is less reason to use the new ISA" and "Investment options are too limited."
On top of this, since the contract period for the existing ISA is capped at a maximum of five years, the strategy of maintaining an account over a long period to enjoy compounding effects has become constrained. The carryover of annual contribution limits has also been abolished, making it impossible for subscribers with irregular income, such as those new to the workforce or the self-employed, to concentrate funds at the point when they receive a windfall such as a bonus. This is why critics say the change has tied down the flexibility of fund management for ordinary and middle-class people who cannot fill their limit each year.
In addition, the government plans to apply a sunset deadline through the end of 2029 to the general ISA, as with the productive finance ISA, before conducting a comprehensive performance evaluation. For this reason, the assessment is that the continuity of a system supporting long-term asset formation has also been weakened. Park Hoon, a professor of taxation at the University of Seoul, said, "Considering the continuity of the system, even if a new system is introduced, the benefits of the existing system should have been maintained." He added, "From the perspective of supporting long-term investment, it is not good for the system to change frequently."
