What’s Inside the E-Book?
Poland’s Real-Time VAT & KSeF in a Nutshell
A clear overview of Poland’s move to a centralized, clearance-style CTC model via KSeF, where FA(3) XML invoices are validated, assigned a KSeF ID and UPO, and only then made available to buyers.
Key Dates & Go-Live Timeline
A practical timeline of open testing, certificate applications, mandatory issuance and receipt dates, the general grace period until 31 December 2026, and the deferred date for micro-entrepreneurs from 1 January 2027.
Scope: Who Must Use KSeF?
Clarity on which entities fall under the mandate: taxpayers established in Poland, foreign entities with a Polish fixed establishment, and how obligations differ when there is no Polish FE or it does not participate in the supply.
KSeF Operations & FA(3) XML
Step-by-step explanation of how FA(3) XML invoices are submitted via API or taxpayer application, validated by KSeF, and delivered to buyers inside KSeF or, where permitted, outside KSeF using a visualisation.
Delivery Rules, QR Codes & Outside-KSeF Flows
Guidance on when invoices can be delivered outside KSeF, mandatory QR code requirements on visualisations, and how to keep a single source of truth across XML and PDF/print outputs.
Exception Handling & Outage Scenarios (Offline24 / Emergency)
A breakdown of how to operate under Offline24 (issuer-side outage) and Emergency (authority-announced outage), including upload deadlines, labelling, and resubmission playbooks.
Key Compliance Considerations & Penalties
Summary of key obligations, potential penalties for non-compliance, and how Poland’s e-invoicing regime impacts AP/AR operations, VAT control, and risk management.
Strategic Readiness & Automation
Practical recommendations on data quality, pre-submission validations, exception handling, and designing automated, real-time KSeF processes that support finance, tax, and IT teams end-to-end.
