As a reminder, the Act amending the Act on Tax on Goods and Services and certain other acts (government draft) introduces, from July 1, 2024, the obligation to issue invoices via the National e-Invoice System (KSeF), which is currently a voluntary system. The obligation is to apply to invoices confirming transactions between entrepreneurs; it will not apply to situations where the buyer is a consumer. That means that currently, entrepreneurs can (from January 1, 2022) voluntarily issue invoices via KSeF. E-invoices act as one of the approved forms of sales documentation, next to paper invoices and electronic invoices that are already in circulation. The Sejm will now decide on the future fate of the act. Stay tuned.
