- From July 1, 2024, taxpayers will be required to issue invoices in the National e-Invoice System (KSeF).
- Currently, duplicate invoices can be issued if the original invoice is lost or damaged, but with the implementation of KSeF, duplicate invoices will no longer be necessary.
- In the event of an electronic invoice being lost or damaged, the taxpayer can provide a new copy or reissue the invoice based on the data provided by the buyer.
- In the case of a paper invoice being lost or damaged, the taxpayer can provide a new copy based on the data provided by the buyer or based on the data from the original invoice in the possession of the taxpayer.
- During the transitional period, duplicates will only be issued for invoices issued before the mandatory use of KSeF.
- From July 1, 2024, buyers of agricultural products or services from flat-rate farmers will be able to issue VAT RR invoices and corrections in KSeF with the consent of the flat-rate farmer.
- VAT RR invoices issued in KSeF will need to include only the tax identification numbers of the supplier and the buyer.
- Flat-rate farmers will need to authenticate themselves in KSeF and submit a declaration stating that they are VAT-exempt flat-rate farmers in order to issue structured invoices.
