Substitute Certification Declaration Form for the Revenue Agency

The self-certification is one of the key tools legislators have used to simplify the relationship between citizens and public administration. Introduced by Presidential Decree No. 445 of December 28, 2000, it allows citizens to personally certify, under their own responsibility, a series of states, qualities, and facts concerning themselves, replacing the traditional certificates issued by public offices. The rationale behind this initiative is clear: when a piece of information is already present in the public administration's archives, it makes no sense to impose on the citizen the burden of requesting and submitting a certificate confirming its existence again. The administration itself will verify this, even retrospectively, through its own information systems.

On this page, the Agenzia delle Successioni provides a free, fillable version of the self-certification form, adapted from the official Revenue Agency template. This practical and straightforward tool allows you to enter data directly online, eliminating the need for manual transcriptions or generic templates. Downloading the pre-made form speeds up processing and reduces errors, simplifying subsequent submission to the competent authority.

What information can be provided in the self-certification declaration?

The self-certification is based on a key principle of contemporary administrative law: the citizen's self-responsibility . The declarant is placed at the center of the administrative process as a fully informed and legally accountable individual for the truthfulness of his or her declaration. The Public Administration accepts the declaration as fully valid, subject, of course, to the power to conduct subsequent checks. Consequently, the institution does not eliminate the certainty of the information, but simplifies the verification process.

Article 46 of Presidential Decree 445/2000 establishes the information that can be self-certified. These are states and facts that, by their nature, are already available through public archives: date and place of birth, residence, citizenship, marital status, family composition, existence, registration in professional registers, orders, or lists, possession of educational or professional qualifications, income or contribution status, tax code or VAT number, student, unemployed, or retired status, military service status, and other information directly related to the individual's personal sphere and already recorded with administrative bodies.

What is the purpose of the self-certification declaration?

The self-certification can be used in all relationships with the Public Administration and public service providers, who are required to accept it. It can also be used in relationships with private entities, such as banks or insurance companies. In this case, however, the private individual has the right to decide whether to accept the declaration or request additional formalities, such as signature authentication. In relationships with public offices, however, the self-certification is always valid and cannot be refused, as the law requires the Public Administration to acquire and verify the information available in its databases ex officio.

From a practical standpoint, the self-certification is an extremely simple document. Citizens must provide their personal details, specify the recipient institution or office, include the declaration regarding the status they intend to certify, and sign it. All requests and declarations to be submitted to public administrations or to managers or providers of public services can also be sent by fax or electronically. Requests and declarations submitted electronically are valid if signed with a digital signature or when the signatory is identified by the computer system using an electronic identity card.

Substitute declaration of certification and successions

In the context of inheritance, the self-certification declaration plays a particularly important role, as it simplifies numerous steps that once required certificates issued by the civil registrar or other public bodies.

Within a probate procedure, much of the information needed to initiate and manage the process is already known at the registry office or otherwise recorded at municipal offices, the National Institute of Social Security (INPS), or the Revenue Agency. The deceased's residence, the heir's family status, marital status, citizenship, student or retired status: all of this information no longer requires formal certification, because the interested party can declare it directly through a signed self-certification, accompanied by a copy of their identity document. In this regard, the fillable form at the bottom of the page eliminates waiting times at the counters, certification costs, and the production of often redundant documents.

How long is the self-certification declaration valid?

The declaration remains valid until it is determined to be false. If the administration's checks reveal that the declaration is false, the citizen will be criminally liable , pursuant to Article 76 of Presidential Decree 445/2000, in addition to forfeiting any benefits obtained based on the declaration. This provision clearly demonstrates the balance between administrative simplification and legality: the Public Administration waives the requirement for material certifications, but retains the power to verify and impose sanctions where necessary.
