- In 2026, the KSeF system will contain “phantom invoices” that mimic real VAT invoices.
- These phantom invoices arise when electronic VAT invoices are first sent to contractors and later uploaded to KSeF, sometimes weeks apart.
- This creates confusion over which document is the official VAT invoice and which “receipt” of the invoice is legally binding.
- The situation may lead to legal and accounting absurdities, such as double receipt of invoices and uncertainty about payment deadlines.
- The author suggests only the first document should be considered the real VAT invoice, while the KSeF version is merely a copy without legal effect.
