How to draft a tax appeal to the Second Instance Court with AI
4 min read · Updated June 2026 · Editorial oversight: Avv. Federico Papa
The tax appeal (Appello) is the ordinary remedy available against judgments issued by the First Instance Tax Courts, aimed at obtaining a full review of the merits of the dispute by a superior collegiate body. The governing provisions are set forth in Art. 53 of Legislative Decree 546/1992, which establishes the formal and substantive requirements necessary for the appeal to be admissible. This document cannot consist of a mere restatement of the original petition's grounds; it must be structured as a precise and specific challenge to the findings of the judgment under appeal. The appeal must be addressed to the Second Instance Tax Court (Corte di Giustizia Tributaria di secondo grado, CGT) with territorial jurisdiction over the seat of the court that issued the first-instance ruling. Strict compliance with statutory deadlines is required, distinguishing between the short deadline triggered by the service of the judgment and the long deadline applicable absent service. The articulation of the grounds must comply with the prohibition against introducing new claims or exceptions not ex officio detectable, under penalty of inadmissibility pursuant to the rules of reformed tax procedure.
In brief
The appeal to the Second-Instance Tax Court is governed by Art. 53 of Legislative Decree 546/1992. Admissibility depends on specific grounds of challenge, prohibiting the simple restatement of first-instance claims. Statutory deadlines are 60 days from service or six months otherwise. Appearance must be completed via the SIGIT portal within 30 days of service. Applications for stay of execution under Art. 52 require proof of fumus boni iuris and periculum in mora. The Unified Tax Contribution follows D.P.R. 115/2002. AI supports the drafting of specific legal grounds.
The steps
- 1.
Identification of deadlines and jurisdiction
Counsel must first verify the timeliness of the appeal by determining whether the judgment was served (60-day short deadline under Art. 51 D.Lgs. 546/1992) or not (six-month long deadline under Art. 327 c.p.c.). The appeal must be lodged with the Second Instance Tax Court in whose district the First Instance Court that rendered the judgment is located. The correct identification of the competent court and the strict tracking of filing deadlines within the SIGIT portal are mandatory requirements for the validity of the proceeding.
- 2.
Drafting specific grounds of appeal
Pursuant to Art. 53 of Legislative Decree 546/1992, the appeal must set out the specific grounds for challenge, under penalty of inadmissibility. A generic request to reverse the ruling is insufficient; counsel must precisely identify the passages of the first-instance reasoning deemed erroneous in fact or in law. For each challenged head of the judgment, counsel must explain the grounds of illegality, linking the arguments to the documentary evidence and the legal provisions infringed.
- 3.
Inclusion of the application for stay of execution
If the enforcement of the judgment or underlying tax assessment risks causing severe and irreparable harm to the taxpayer, a specific application for a stay must be included under Art. 52 of Legislative Decree 546/1992. The appellant must demonstrate both fumus boni iuris, meaning the reasonable likelihood of success on the merits, and periculum in mora, understood as imminent and otherwise irreparable prejudice. The application may be embedded in the appeal brief or filed as a separate motion, requesting the Court to suspend the enforceable effects of the challenged judgment.
- 4.
Service and electronic filing
The appeal brief must be served on the counterparty (the relevant Revenue Agency office or local authority) via certified email (PEC) or through the methods prescribed by the technical regulations of the electronic tax process. Within 30 days of service, the appellant must enter an appearance by filing the appeal with the court registry via the SIGIT portal. At this stage, counsel must complete the metadata for the docketing note (nota di iscrizione a ruolo), attaching proof of service, a copy of the challenged judgment, and the power of attorney, unless already granted for both instances.
- 5.
Management of the unified tax contribution
Filing the appeal requires payment of the Unified Tax Contribution (CUT), calculated under D.P.R. 115/2002 according to the value of the dispute. This value equals the sum of the contested tax alone, excluding penalties and interest, except where the lawsuit concerns penalties exclusively. Counsel must include the required declaration of value within the brief and attach proof of payment executed via PagoPA or the F24 form to avoid administrative fines and official payment notices.

Mistakes to avoid
- Lack of specificity in grounds: merely re-submitting the initial petition without targeted objections to the judgment's reasoning results in inadmissibility under Art. 53.
- Introducing new claims or defenses: Art. 57 prohibits raising new claims or non-ex-officio exceptions on appeal that were not presented in the first instance.
- Late filing in SIGIT: failure to complete entry of appearance within 30 days of service renders the appeal irremediably inadmissible.
- Incorrect calculation of the unified contribution: missing or inaccurate declarations regarding the dispute value may trigger tax assessment notices and administrative fines.
