What changes if I move my matured ISA money into a pension account?

If all or part of the balance of an ISA that is more than 3 years past its contract date is paid into a pension account, that ISA is deemed to have reached the end of its contract period.

According to the National Tax Service, amounts paid into a pension account within 60 days of the ISA's maturity date can be contributed separately from the annual pension account contribution limit (KRW 18 million). For specifics such as the tax benefits of the transfer, check with the National Tax Service or your financial company.
