As the income tax declaration season approaches, various tax deadlines are approaching for Italian taxpayers and employers in March 2026. The article highlights the obligations that include stamp duties on invoices, debt settlement procedures, and payment schedules for those holding VAT numbers. In particular, the first half of the month will be particularly busy for these taxpayers, with reminders to mark important dates on their calendars.

Key deadlines begin on March 2, 3, and 9, when VAT holders must address significant compliance requirements. The first important task is the payment of the stamp duty on electronic invoices issued during the fourth quarter of 2025 (October-December). Moreover, those who opted for the two-year preliminary agreement in 2024 and chose special recovery for the period 2018-2022 will also need to fulfill their obligations following any delays that have occurred.

The latter part of March introduces the first phase of the income tax filing season with the distribution of unique certifications for 2025 to workers. These certifications are crucial for employees as they provide the necessary documents for their tax declarations. Taxpayers are urged to stay informed about these deadlines to avoid penalties and ensure compliance to facilitate smoother tax processing.
