What each status means
Scheduled maintenance
A planned maintenance window is in progress. Some services may be unavailable during this time.
Failure
An incident is ongoing - some operations may fail. Invoices issued in offline mode must be sent to KSeF within 7 business days after the incident ends (art. 106nf of the Polish VAT Act).
Total failure
KSeF is completely unavailable. A total failure is announced by the Ministry of Finance in public media - invoices are then issued outside KSeF (on paper or electronically) and are not sent to KSeF afterwards.
Frequently asked questions about KSeF status
Where does the KSeF status data come from?
We fetch the data directly from the public Latarnia KSeF API run by the Polish Ministry of Finance (api-latarnia.ksef.mf.gov.pl). We do not modify or delay the information - we display exactly what MF publishes. The status refreshes every 60 seconds.
What does AVAILABLE mean?
KSeF is fully operational. Invoices can be issued, sent and retrieved normally. This is the system's normal operating state.
What does MAINTENANCE mean?
The Ministry of Finance has scheduled maintenance and announced it in advance. During that time, some or all KSeF services may be unavailable. The date and scope of the break are shown in the announcements below the status.
What should I do during a KSeF incident (FAILURE or TOTAL_FAILURE)?
With FAILURE, some operations may fail - you can issue invoices in offline mode and send them to KSeF within 7 business days after the incident ends (Article 106nf of the Polish VAT Act). With TOTAL_FAILURE, KSeF is completely unavailable - such a failure is announced by the Ministry of Finance in public media, and invoices issued during it are not sent to KSeF.
How often is the status on this page updated?
The page queries Latarnia KSeF every 60 seconds and automatically updates the displayed status. You can also force a refresh by clicking the Refresh button next to the last check time.
Can I issue invoices during a KSeF outage?
Yes - you can prepare and save an invoice in KSeFGPT at any time. You send it to KSeF manually when the system is available. During FAILURE, you issue invoices in offline mode and send them to KSeF within 7 business days after the incident ends (Article 106nf of the Polish VAT Act); during TOTAL_FAILURE, invoices are not sent to KSeF at all.
