Annual development of FS call center performance comparing 2015 to 2025. Information is provided to tax entities via 3 main information channels: mail (Live Agent), telephone calls (call center) and chat (Live agent). The number of completed submissions of entities in individual years is affected by the adopted legislative changes and their impact on the fulfillment of tax obligations. During times of major legislative changes, the number of inquiries increases significantly. In 2021 and 2022, the increase in inquiries compared to other monitored years was influenced by two MFSR projects during the COVID pandemic, namely the vaccination lottery / 2021/, and the vaccination bonus for seniors / 2022/, in which the FS Call Center provided massive support to citizens who participated in the vaccination lottery. In 2025, call center performance was affected by major legislative changes to existing tax laws and the adoption of two new laws, namely the financial transaction tax and the tax on sweetened beverages as part of the second and third consolidation packages of the Slovak government.
