Poland is making significant strides with its KSeF 2.0 e-invoicing system, with mandatory implementation rolling out in phases. Large companies must comply starting February 1, 2026, followed by all other businesses by April 1, 2026, and micro-businesses by January 2027. Key enhancements include permanent offline invoicing capabilities, new QR code requirements, and updates to the API and compliance rules. The system’s rollout involves public testing beginning September 2025, with final legal approvals anticipated in July 2025. Offline24 mode will permit delayed invoice submission, and a single QR code format will be used for printed e-invoices. Furthermore, new regulations will mandate KSeF numbers on bank transfers and invoices, alongside clarifying GDPR compliance and supporting invoice attachments.
