Government Reverses ISA Restriction Plans in Final Tax Reform

In a significant policy U-turn confirmed at the Cabinet meeting on September 1, the government withdrew its initial proposal to impose a five-year cap on ISA contract periods and ban the carryover of unused annual contribution limits. This revision follows intense backlash from individual investors and criticism that the original plan discouraged long-term asset management. The final government bill submitted to the National Assembly retains the existing ISA structure, ensuring that investors can continue to utilize carryover benefits and longer-term contracts without the previously proposed restrictions.

New Guidance Clarifies Retirement Payout Tax Breaks

Seoul Economic Daily reported on September 12 that Korea’s tax break on severance pensions is now explicitly counted from the moment withdrawals begin, rather than how long an Individual Retirement Pension (IRP) account has been held. Under this clarified rule, payouts extending beyond 20 years are subject to lower taxation rates. This distinction is critical for retirees planning their income streams, as it decouples the tax benefit from the accumulation phase and ties it strictly to the distribution timeline.

Savings Bank Rates Fall While Mutual Finance Institutions Rise

Data from September 12 highlights a growing divergence in deposit rates: while savings banks (저축은행) saw their 4%+ products disappear rapidly, mutual finance institutions like Saemaul Geumgo and credit unions raised their top rates to 4.3%. As of early September, the average one-year deposit rate at nationwide savings banks dropped to 3.74%, down from 3.95% in July, despite the Bank of Korea’s recent base rate hikes. This "reverse money move" sees savers flocking to mutual finance institutions and commercial banks offering more competitive yields compared to the retreating savings bank sector.

Local view

Local media outlets have focused heavily on the government’s abrupt reversal on ISA reforms. Aju News published a critical editorial on September 13 titled "Tax Reform U-Turn in One Month: Where is the Government Going?", highlighting President Lee Jae-myung’s earlier comments questioning the lack of preparation in the initial ISA overhaul proposal. The outlet notes that the rapid shift from announcing restrictions to maintaining the status quo has created uncertainty among retail investors who had rushed to lock in terms before the rumored changes took effect.

Additionally, Financial News reported on September 13 that the gap between deposit and lending rates (예대금리차) is narrowing as banks raise deposit rates faster than loan rates following the base rate hikes. This trend is being watched closely by local stakeholders as it impacts bank profitability and the attractiveness of traditional savings products versus equity markets.
