As of 1 July 2016 all large enterprises in Poland are obliged to transfer Standard Audit File for Tax (SAF-T) to the Polish Ministry of Finance. Poland is yet another country which decided to adopt this regulation (other SAF-T adopters include Portugal, Luxembourg, France, Austria, Lithuania). The new law made Polish IT providers introduce certain system updates so as to allow their business clients to generate the tax books required by the Ministry of Finance. This data must be electronically transmitted to the tax authorities according to the clear-cut specification, what proved to be a challenge for numerous Polish entrepreneurs, since the majority of enterprise software does not offer such a possibility. Consequently, IT solutions, acting as the operator between ERP system and the tax authority, have appeared on the market.
