Tax Litigation in Italy: How It Works, What It Costs and How Long It Takes
A practical guide to Italian tax proceedings: from service of the disputed document to an appeal before the Tax Courts (Corti di Giustizia Tributaria), through to the Italian Supreme Court (Corte di Cassazione). The Firm Marzo Associati represents clients throughout Italy through the electronic tax court filing system (PTT).
In Brief
Tax litigation in Italy takes place before the Tax Courts (Corti di Giustizia Tributaria) (of first and second instance), established by D.Lgs. 545/1992 and extensively reformed by L. 130/2022 and D.Lgs. 220/2023. The standard deadline for challenging a document is 60 days from service. Proceedings are conducted entirely electronically through the electronic tax court filing system (PTT), allowing legal representation from anywhere in the country: the Firm Marzo Associati assists clients throughout Italy, with an operating office in Rome.
The New Structure of Tax Proceedings
Since 16 September 2022, under legge 130/2022, the longstanding Provincial and Regional Tax Commissions have been replaced by the Tax Courts (Corti di Giustizia Tributaria) of first and second instance. This is not merely a change of name: for the first time in the tax justice system, the reform introduced professional, full-time tax judges recruited through a competitive examination, who will gradually replace the honorary judges currently in office.
This structural reform was supplemented by D.Lgs. 220/2023, in force since 4 January 2024, which revised numerous procedural rules: abolition of mandatory tax mediation, extension of judicial conciliation, introduction of prova testimoniale scritta, strengthening of the right to be heard before a decision is made (art. 6-bis dello Statuto del Contribuente), and new rules on public hearings and litigation costs. For anyone facing litigation today, understanding these changes is crucial: a defence based on the old framework risks missing opportunities available under the new rules.
The Tax Courts (Corti di Giustizia Tributaria) have exclusive jurisdiction over all disputes concerning taxes of every kind, however named: national taxes (personal income tax (IRPEF), corporate income tax (IRES), VAT, registration tax), local taxes (municipal property tax (IMU), TARI, surtaxes), ancillary charges (penalties, interest, collection fees) and tax enforcement measures up to seizure (without prejudice to the jurisdiction of the ordinary courts over challenges to enforcement following service of the enforceable instrument).
The Three Levels of Tax Proceedings
Italian tax proceedings have a three-tier structure: two levels dealing with the merits (Tax Courts (Corti di Giustizia Tributaria) of first and second instance) and one dealing with points of law (the Tax Division of the Italian Supreme Court (Corte di Cassazione)). Understanding what is considered at each level is essential to developing an effective defence strategy.
First Instance — Tax Court (Corte di Giustizia Tributaria) of First Instance
This is the taxpayer's legally designated court. It sits in every provincial capital. It considers facts, documentary evidence, and procedural and substantive defects in the disputed document. An appeal must be brought within 60 days of service. Its judgment may be appealed within 60 days of service (or 6 months of filing).
Second Instance — Tax Court (Corte di Giustizia Tributaria) of Second Instance
It sits in regional capitals. It is the appellate court: it re-examines the merits of the case within the scope of the grounds of appeal. New documentary evidence may be submitted within the limits of art. 58 of D.Lgs. 546/1992. Its judgment may be appealed to the Italian Supreme Court (Corte di Cassazione) on points of law only.
Third Instance — Tax Division of the Italian Supreme Court (Corte di Cassazione)
Its sole seat is in Rome, Piazza Cavour. Only errors of law and defects in the reasoning are considered (art. 360 c.p.c.). An appeal requires a lawyer admitted to practise before the Italian Supreme Court (Corte di Cassazione). The Court may decide the merits or quash the judgment and remit the case to the Tax Court (Corte di Giustizia Tributaria) of second instance with a differently constituted panel.
Tax Courts vs the Italian Supreme Court (Corte di Cassazione) in Tax Cases: Comparison Table
Understanding the differences between proceedings before the Tax Courts (Corti di Giustizia Tributaria) and those before the Tax Division of the Italian Supreme Court (Corte di Cassazione) is essential to developing a defence strategy that takes account of the limits and opportunities at each level of tax litigation.
| Profile | CGT 1° e 2° grado | Tax Appeals to the Italian Supreme Court (Corte di Cassazione) |
|---|---|---|
| Nature of the Proceedings | Merito (fatti e diritto) | Review of Legality (Points of Law Only) |
| Issues Considered | Procedural defects, evidence, factual findings, application of the law | Errors of law, defects in the reasoning (art. 360 c.p.c.) |
| Time Limit for Appealing | 60 days from service of the act / judgment | 60 days from service of the second-instance judgment (6 months from filing) |
| Required Legal Representative | Lawyer, chartered accountant, authorised employment consultant | Only a lawyer admitted to practise before the Italian Supreme Court (Corte di Cassazione) (entered on the special register) |
| New Evidence Admissible | Yes at first instance; on appeal within the limits of art. 58 D.Lgs. 546/1992 | No: the decision is based on documents already on the court file |
| Average Duration | 12-24 mesi (1° grado), 12-18 mesi (appello) | 3–5 years from service of the appeal |
| Typical Outcome | Judgment allowing the appeal in full or in part, or dismissing it | Quashing with remittal, decision on the merits or dismissal |
| Location | Provincial capital (first instance) / regional capital (second instance) | Rome, Piazza Cavour (sole seat) |
| Unified Court Fee | €30 – €1,500 (based on the value of the dispute) | Doubled if the appeal is unsuccessful (art. 13, c. 1-quater DPR 115/2002) |
The distinction is crucial: an error of fact not raised in time before the courts ruling on the merits cannot be raised later before the Italian Supreme Court (Corte di Cassazione). For this reason, the defence at the first two instances of tax litigation must be structured with a potential future appeal on points of law in mind — anticipating legal issues and carefully documenting every piece of evidence.
Tax Litigation: Timeframes, Costs and the Unified Court Fee
The duration of tax litigation varies significantly depending on the court and the complexity of the case. On average, the prima sentenza is delivered within 12–24 months of service of the appeal; theappello takes a further 12–18 months; proceedings before the Italian Supreme Court (Corte di Cassazione), finally, may take 3–5 years from service of the appeal to filing of the judgment. Courts in northern Italy generally have shorter timeframes, while some Tax Courts (Corti di Giustizia Tributaria) in central and southern Italy have significant backlogs.
In financial terms, the main initial cost is the unified tax court fee, based on the value of the dispute: €30 up to €2,582.28; €60 up to €5,000; €120 up to €25,000; €250 up to €75,000; €500 up to €200,000; €1,500 above €200,000. Added to this are the legal representative’s fees (parameters under DM 55/2014, which may be reduced or increased depending on complexity) and any fees for expert advice commissioned by the party.
It should be remembered that, if a party loses, the court orders that party to pay the litigation costs to the opposing party, unless the court gives reasons for ordering the parties to bear their own costs in whole or in part. A preliminary assessment of litigation risks is therefore an essential part of responsible representation: before proceedings are commenced, the Firm always provides a realistic estimate of the prospects of success and the overall financial exposure.
The Electronic Tax Court Filing System and Nationwide Representation
Since 1 July 2019, the electronic tax court filing system (PTT) has been mandatory for all appeals brought by authorised legal representatives: service by certified email (PEC), electronic filing of documents, a digital case file and court registry communications by PEC. The PTT has eliminated the need for physical attendance at court registries and has made it possible for a firm based in Rome to represent a taxpayer in Milan, Naples or Bari with the same operational efficiency as local representation.
In addition, the udienze pubbliche may be held remotely, at the joint request of the parties or by direction of the presiding judge (art. 16 del D.L. 119/2018, converted into L. 136/2018, and subsequent additions). Determination on written submissions, introduced generally under emergency legislation and subsequently made permanent, is now an established option in tax proceedings.
This digital framework makes the geographical distance between the taxpayer and their legal representative entirely irrelevant: what matters is specializzazione. In tax law, where the subject continually evolves through legislation, implementing decrees and case law of the Italian Supreme Court (Corte di Cassazione), choosing a firm dedicated exclusively to this area offers a substantial competitive advantage over a local general practice firm.

Dispute Resolution Procedures: Alternatives to an Appeal
An appeal is not always the most suitable solution. Italian tax law provides for several procedures that allow disputes to be resolved before or during court proceedings, with reduced penalties and costs.
Tax Settlement Procedure (accertamento con adesione) (D.Lgs. 218/1997)
A procedure involving discussions with the tax office before an appeal, with penalties reduced to one third of the statutory minimum. It suspends the time limit for appealing for 90 days.
Self-Correction Request (autotutela) (art. 10-quater Statuto del Contribuente)
A reasoned request for the cancellation or amendment of the notice, submitted directly to the tax office. Since January 2024, it has been subject to stricter rules, with mandatory self-correction in cases of manifest error.
Conciliazione giudiziale (art. 48 D.Lgs. 546/1992)
An agreement between the taxpayer and the tax office during proceedings, with a reduction in penalties ranging from 50% to 30%, depending on the level of proceedings at which it is reached.
Tax Amnesty Settlement of Outstanding Disputes ("rottamazioni")
Measures introduced periodically by the legislature that allow pending disputes to be settled by paying only the principal and statutory interest, without penalties. They must be assessed on a case-by-case basis against the strength of the arguments for the defence.
