The proposal and discussion of a new fiscal law in Slovakia took place in 2018, with a focus on an online connection to the Tax Authority. The law stated that all retailers must comply with the new regulations starting on April 1st, 2019, with full implementation set for July 1st, 2019. Retailers who were required to register sales under the new law for the first time were mandated to use the E-Kasa system set up by the Slovakian Tax Authority for the purpose of fiscalization. Every taxpayer needs to create a profile on the E-Kasa platform.
Type of fiscalization: Hardware/Software
