KSeF E-Invoicing MYTH 2 – Since when is KSeF mandatory?

• All taxpayers, regardless of their sales volume, will be required to collect invoices issued in the KSeF starting February 1, 2026, even though some will only be obligated to issue invoices in the system from April 1, 2026.
• From February 1, 2026, issuing invoices through KSeF will become the default invoicing method in Poland, with no need for recipient consent, and the receipt of structured invoices will be linked to their approval in the KSeF system.
• Sellers will not be required to notify buyers of issued invoices in KSeF, placing the onus on buyers to implement systems or procedures to check and process their new purchase invoices effectively.
