In Brief
A tax lawyer in Rome assists taxpayers, businesses and corporate groups in all disputes with the Italian Revenue Agency (Agenzia delle Entrate), the Italian Tax Collection Agency (ADER) and the Italian Finance Police (Guardia di Finanza). They handle challenges to tax assessment notices, tax payment notices (cartelle), formal demands for payment, administrative vehicle seizures (fermi amministrativi) and tax mortgages (ipoteche), from the pre-litigation stage through to appeals on points of law before the Italian Supreme Court (Corte di Cassazione). The Firm Marzo Associati operates throughout Italy from Rome using the electronic tax court filing system (PTT).
Recognition of Our Tax Law Firm in Rome
Marzo Associati is a Rome-based tax law firm with documented recognition: inclusion in Il Sole 24 Ore – Statista's "Gli Studi Legali dell'Anno 2026" rankings, inclusion in Forbes Italia's "Eccellenza 2025" rankings, a Legalcommunity Italian Awards award in the Fiscalità del Gambling category, and mentions in We Wealth. Lawyer Giancarlo Marzo is the author of the handbook "Fiscalità del Gaming", published by Giuffré Francis Lefebvre.
The Firm comprises 8 professionals, including tax lawyers, chartered accountants and tax specialists, who work in an integrated manner. Our approach always involves, before any proceedings are commenced, an valutazione preliminare onesta of the prospects of success and the overall financial exposure. We do not promise certain victories: we provide technical analyses on which to base informed decisions.
We operate throughout Italy using the electronic tax court filing system (PTT): our appeals are regularly filed before the Tax Courts (Corti di Giustizia Tributaria) in Milan, Naples, Turin, Bologna, Florence, Bari and Palermo. Moreover, the Tax Division of the Italian Supreme Court (Corte di Cassazione) has its sole seat in Rome, in Piazza Cavour: for appeals on points of law, having a Rome-based firm offers a tangible operational advantage.
