All tax amounts were transferred to a single account in Poland until 31 December 2019.
As of 1 January 2020, every tax payer in Poland has their own tax account with an individual IBAN, which they need to use for all (including retroactive) payments. You can easily find out the IBAN yourself – we explain this in another support article (link).
What happens if I continue to use the old IBAN?
The old IBAN is expected to be deactivated on 1 January 2020. After this date, it's therefore possible that all payments made to this account will be rejected. This would result in additional bank fees, so the new IBAN should definitely be used.
What happens if I use the new IBAN before 1 January 2020?
The new accounts will not be activated until 1 January 2020. Before this date, it's likely that all payments made to the new IBANs will be rejected.
Will my new IBAN change again?
No, the new IBANs are permanent and will not change. You can therefore save the IBAN in your transfer templates, for example.
