Webinar: KSeF implementation – key legal and tax issues

In July 2024, the National e-Invoicing System (KSeF) will come into force in Poland. There is little time left to prepare for the implementation of the system and the new regulations still raise many doubts among entrepreneurs. We would like to invite you to watch a recording of our webinar, during which we answered the most frequent questions of companies on KSeF-related legal and tax issues.

Location: Poland, Online
Date of the webinar: 29 November 2023, 11 AM – 12 PM CET
Language: English / Polish language version available

Switching to e-invoicing means that taxpayers need to adapt not only their IT systems but also their invoice workflow processes to the new rules. It is also very important to prepare the organisation from a legal and tax perspective. There will be financial penalties for failing to comply with the obligations, which will start to be imposed six months after the KSeF comes into force, i.e. from 1 January 2025.

What do companies need to pay particular attention to when preparing for KSeF implementation? What does the entry into force of e-invoices mean for foreign entities? How to deal with system failures and what financial penalties may be imposed?

During the webinar, we discussed the legal and tax issues related to KSeF that are of most concern to companies.
