Italy tax deadlines: How to regularize Modello 730 filings

Taxpayers in Italy who missed the September 30 deadline for the Modello 730 can regularize their position through the 'ravvedimento operoso' process. If the correction is made within 90 days of the deadline, the standard 250 euro administrative sanction can be reduced to 25 euros. To do this, taxpayers must use tax code 8911 in the Erario section of the F24 form.

Beyond the 90-day window, omissions can lead to much higher penalties, ranging from 120% to 240% of the taxes owed. For those needing to correct or integrate an already submitted 730, there are two primary paths. If the correction results in a more favorable tax outcome or no change to the balance, a '730 integrativo' can be submitted by October 26. Alternatively, the 'Redditi PF' model can be used for corrections or integrations until November 2.
