Codice ATECO
Also known as: ATECO code, activity classification code
An ATECO code classifies your business activity in Italy's official statistical taxonomy (ATECO 2025, in force since 1 January 2025, maintained by ISTAT). You pick one when you open your partita IVA. It drives your reporting obligations and, under the forfettario, the profitability coefficient (40%–86%) applied to your revenue.1
What this means for you
Choosing the right code matters: it sets how much of your revenue is taxed under the forfettario (e.g. 78% for most professional services, 40% for retail). The wrong code can mean the wrong tax base — your commercialista confirms the final choice.
