KSeF Status

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.

KSeF is fully operational. Invoices can be issued, sent and retrieved normally. This is the system's normal operating state.

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.

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.

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.

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.
