The Italian Tax Authority (Agenzia delle Entrate) has launched audits to verify compliance with the mandatory connection between POS terminals and electronic cash registers (registratori telematici), an obligation in force since 1 January 2026. We covered the launch of the Tax Agency’s web service in our earlier article on POS–cash register connection. We therefore urge all affected clients to check their status without delay in the reserved area of the “Fatture e Corrispettivi” portal.
What the obligation requires
Since 1 January 2026, businesses required to electronically store and transmit sales data must integrate their payment and receipts processes. In practice, this means three things. First, all POS terminals must be logically linked to the electronic cash register (RT or Server RT) or to the “Documento commerciale online” web procedure. Second, the payment method used by the customer must be correctly recorded on the commercial document. Third, electronic payment data must be stored and transmitted in aggregated form. The connection is made through the dedicated service in the reserved area of the “Fatture e Corrispettivi” portal.
Deadlines: the 20 April 2026 cut-off has already passed
For POS terminals active in January 2026, the connection deadline was 20 April 2026 — now expired. For terminals activated after 31 January 2026, the connection must be made from the sixth day of the second month following the date the device became available, and no later than the last working day of that month. The same deadline applies whenever an existing connection changes — for example, when a POS is replaced or moved, a new cash register is activated, or a device is decommissioned.
What to check in your reserved area
We recommend verifying the following points. Check that no active POS terminals appear as unlinked in the portal. Confirm that any new POS devices have been properly associated with their cash register. Ensure that any changes to existing connections have been reported. Verify that decommissioned POS terminals are correctly managed within the system. Finally, confirm that the payment method shown on the commercial document matches what the customer actually used. Extra care is needed where multiple POS terminals, multiple cash registers, virtual POS devices, or device replacements are involved.
Applicable penalties
Failure to link a POS terminal to the fiscal certification system carries an administrative fine of between €1,000 and €4,000. In more serious cases, additional sanctions apply. These can include the suspension of the business licence or operating authorisation. Separate penalties are also provided for incorrect storage or transmission of payment method data.
Businesses that have not yet complied, or that are uncertain about their connections, should act immediately.
