IIS: strategies and nuances: how not to lose your deduction when closing an account?

Preserving the tax deduction when closing an Individual Investment Account requires strict compliance with legislative norms and timeframes. The main rule for successfully receiving the tax benefit is not to close the account before the established minimum period, which for accounts opened before 2024 is three years. If you withdraw money or securities even a day ahead of schedule, the right to the tax deduction is completely canceled, and the funds already received from the state must be returned along with penalties.

To minimize financial risks before closing the account, it is extremely useful to calculate both a baseline scenario and a stress scenario. Always build in a time and monetary buffer of 10–20 percent so that unforeseen delays by the broker or bank do not disrupt your plans. Decide in advance which expenses or regular contributions you are ready to cut first if you need to urgently top up the account to preserve the maximum deduction base. Such a financial buffer will protect you from spontaneous and unprofitable decisions at the final stage of the investment period.
