Poland: invoice VAT receipt date tied to KSeF number assignment, not accounting entry
In Poland, a structured invoice's VAT receipt date is when KSeF assigns its identification number, not when it enters an accounting program. Monthly VAT payers can deduct input VAT up to three months after assignment.
Poland’s tax authority has clarified that for VAT purposes, a structured invoice in KSeF is considered received on the date its KSeF identification number is assigned. This receipt date determines when input VAT deduction rights arise, regardless of when the invoice is technically downloaded into accounting software. Monthly VAT payers have flexibility to claim the deduction in one of three subsequent accounting periods.
For VAT purposes in Poland, the date a structured invoice receives its KSeF identification number is the date it is considered received for tax law. This is true regardless of when the invoice is later downloaded or accepted into an accounting program.
This distinction matters for input VAT deduction. If an invoice was assigned a KSeF number in April, the right to deduct input VAT generally arises in April. However, monthly VAT payers have a grace period. They can claim the deduction in one of the three subsequent accounting periods (May, June, or July).
In practice, this means an invoice can be technically accepted into an accounting program in June while its VAT receipt date remains April. For monthly payers, deducting input VAT in June is permissible, provided all other deduction conditions are met.
The rule applies to all structured invoices submitted to KSeF, Poland’s mandatory e-invoicing system. Businesses must track the KSeF assignment date separately from the accounting entry date to ensure compliance with VAT timing rules.
