The deadline for paying stamp duty on electronic invoices for the third quarter of 30 expires on 2023 November. Compliance can be managed quickly and easily via the Revenue Agency website, which provides a function for the calculation and online payment. Simply access the "Invoices and Fees" portal and automatically and correctly calculate the amount to be paid. We remind you that if the total amount of stamp duty due on invoices issued in the first two quarters does not exceed the amount of 5.000 euros, payment can take place together with the tax due for the third quarter, by 30 November.
