2Hello,
Does MS plan to update the e-invoicing features for Poland related to the requirement to include KSeF numbers in the transfer title?
Starting January 1, 2027, a purchaser of goods or services who is an active taxpayer and who makes payments for KSeF-structured invoices will be required to provide a KSeF number or a collective identifier.
A collective identifier is an aggregate number assigned to at least two structured invoices issued by a given seller.
To generate a collective identifier, a list of KSeF invoice numbers must be declared. The identifier can be generated by either the issuer or, for example, the recipient of the invoices. Generating a collective identifier will be possible both in the KSeF Taxpayer Application and in commercial financial and accounting systems connected to the KSeF API.
KSeF will also allow users to decode a collective identifier, meaning they can check which KSeF invoice numbers it covers. It will also be possible to verify, based on a given KSeF number, in which collective identifiers it has been included.
The collective identifier will allow a single identifier to be listed in the payment description for multiple invoice numbers being paid.
The collective identifier will consist of 35 characters:
the context of the generating entity (Tax ID),
the designation “IZ”,
the year and month the collective identifier was generated,
a unique 12-character string,
two check digits.
Example: 9999999999-IZ202602-FFFFFFFFFFFF-FF
I would appreciate any details on this.
Thank you!
