Italy tax deadlines: CPB and Redditi 2026 filings due November 2

Italian taxpayers face several critical deadlines in late 2026 regarding tax declarations and the biennial preventive agreement (CPB) for 2026-2027. The deadline to join the CPB is November 2, 2026, a date shifted from October 31 due to the weekend. This fiscal tool allows self-employed workers and small businesses to pre-agree on taxable income with the Agenzia delle Entrate, providing greater tax certainty. However, those utilizing the special amnesty for the 2020-2023 period face extended audit windows from the tax authorities until December 31, 2029.

Additionally, the deadline for submitting the Redditi 2026 model is also November 2, 2026. Taxpayers are advised to verify personal data, income figures against Certificazione Unica (CU) documents, and property details to avoid sanctions. For those needing to correct previous 730 filings, deadlines include October 26 for integrative filings via professionals and November 2 for corrections involving increased debt via the Redditi PF model.
