Frekvenca pošiljanja in preverjanja Frequency of sending and verification
Frequency of Sending and Verification
Invoices are sent to the Hungarian tax authority (HuTax) only if they are printed or marked as printed. Every 23 minutes past the hour (00:23, 01:23, 02:23, etc.), a verification of these invoices is performed, and the data is sent to HuTax.
After that, a verification is conducted for invoices that have not yet received a final processing status from HuTax - either DONE or ABORTED.
In practice, this means that after printing the invoice, you should wait a maximum of 1 hour for it to be confirmed, and then an additional hour (depending on HuTax's responsiveness) for the invoice to be appropriately approved / rejected.
Invoice status record
In the invoice, you can see under additional information when the invoice was sent to HuTax and what the acceptance status was.
The status of invoice verification is also displayed in the report: List of issued invoices- V2 
Error: The invoice has been confirmed by the Hungarian tax authority and cannot be modified. Issue a credit note.
If the invoice has been printed and confirmed by the Hungarian tax authority, the data can no longer be changed, as it has already been submitted for confirmation. Therefore, to modify the invoice, a credit note must be issued, and a new invoice created. The invoice can be edited if it has not yet been printed (which means it has not been issued).
Changes that are allowed even if the invoice has already been confirmed by the Hungarian tax authority:
Warning:
As of 1 January 2021, tax certification of invoices is legally required if you have a HU tax number. Due to the trial period, the legal requirement for electronic certification of invoices will commence with invoices issued from 1 July 2021 onwards.
