Frequently asked questions
I'm on the flat-rate regime: do I need to file a return?
Yes: flat-rate taxpayers also file the Modello Redditi every year (section LM) and pay the substitute tax and contributions. We take care of it.
The information on this page is general and up to date as of November 2026: rules and deadlines can change. It does not replace advice on your own case.
