Evidence requests in Polish tax proceedings – when can the tax authority refuse to admit evidence?

Evidence requests in Polish tax proceedings – when can the tax authority refuse to admit evidence?

Taxpayers have the right to contribute to the evidentiary record One of the fundamental principles of Polish tax proceedings is the obligation to establish the facts of the case thoroughly and accurately.

The nature of the dispute: performance vs. acceptance The case concerned a taxpayer providing IT implementation and system upgrade services.

KSeF and foreign entities: when the use of a Polish VAT number triggers mandatory e-invoicing

KSeF and foreign entities: when the use of a Polish VAT number triggers mandatory e-invoicing

The concept of a FE itself has not changed. It has long been part of the VAT system and has been extensively addressed in the European case law. What has changed is the practical relevance of FE in the KSeF environment.
