- The date a VAT invoice is entered into the KSeF system, not its issuance or receipt date, determines when VAT can be deducted.
- Any delay by the seller in submitting the invoice to KSeF can postpone the buyer’s right to deduct VAT by a month or quarter.
- The new rules eliminate backdating invoices; if not entered into KSeF by month-end, VAT deduction shifts to the next month.
- In case of system failures, the actual receipt date applies if earlier than the KSeF entry date, but strict deadlines for entering invoices remain.
- Missing these deadlines can result in penalties, regardless of the reason for the delay.
