How to send the invoice to KSeF
1. Fill in and download the file
Enter the seller, buyer and line items. The generator checks the NIP and calculates VAT. Set the issue date to the day you will send the invoice, then download the XML file.
2. Log in to the KSeF taxpayer app
Go to ap.ksef.mf.gov.pl and log in with a trusted profile (Profil Zaufany), a qualified signature or a KSeF certificate. A KSeF token also works.
3. Load the invoice
Choose Faktury, then Wczytaj fakturę, and add the downloaded XML file. The app checks the file structure before sending.
4. Send it and keep the KSeF number
After sending, KSeF assigns the invoice a KSeF number and issues an official receipt (UPO). The buyer receives the invoice through KSeF.

- Buyer: a company with a NIP, an EU company with an EU VAT number, or a consumer without an ID.

Frequently asked questions
Who must issue invoices in KSeF?
From 1 February 2026, businesses with sales above 200 million zł in 2024; from 1 April 2026, all other taxpayers. Until 31 December 2026, businesses whose invoiced sales stay at or below 10,000 zł gross a month may still invoice outside KSeF. From 1 January 2027, KSeF is mandatory for everyone.
Is the generated file already a KSeF invoice?
No. A structured invoice exists only after the file is sent to KSeF and receives a KSeF number. The generator prepares the XML file that you load in the KSeF taxpayer app.
Is my data stored anywhere?
No. The file is created in your browser. Norman does not send or store the form data.
Which VAT exemption basis should I enter?
For the small-business exemption it is usually art. 113 ust. 1 of the Polish VAT act. For a subject-matter exemption, give the relevant provision, for example art. 43 ust. 1 pkt 37 for insurance services.
What does the np II rate mean?
Services taxed in the EU buyer's country (art. 100 ust. 1 pkt 4 of the Polish VAT act). The buyer accounts for the VAT, and the invoice carries the reverse-charge annotation.
