On 1.12.2010, the European Commission issued a document called the “Green Paper” on the future of VAT. It set out recommendations that were necessary for simpler and more efficient settlement of value added tax. In addition, one of the tools aimed at minimizing tax fraud was to be a system monitoring all invoices in combination with settlements made by entrepreneurs for VAT. The Central Invoice Register will be such a tool in Poland. It is a tool that allows checking the correctness of issuing invoices, analyzing and detecting carousels and eliminating, among others, the so-called empty invoices, i.e. documenting fictitious transactions. In addition, CRF is to streamline and accelerate tax audits.
