- From February 1, 2026, VAT taxpayers with sales over 200 million PLN in 2024 must issue invoices via KSeF; from April 1, 2026, this applies to all others.
- All taxpayers must receive invoices through KSeF from February 1, 2026.
- The law’s provisions on electronic and structured invoices are unclear and internally contradictory, raising concerns about possible double invoicing for the same sale.
- There is confusion about whether sending an invoice to KSeF after sending it to a client constitutes issuing two invoices and if this creates double tax obligations.
- The required content of electronic invoices is also unclear, with taxpayers unsure why they must match the structured invoice template.
