How to keep the condominium's tax documents
The orderly retention of tax documents is one of the administrator's least visible but most important activities. Supplier invoices, F24 receipts, single certifications, traceable transfers and documentation of eligible works must remain retrievable throughout the period in which the condominium or the owners may be called to account for them, in the event of checks or disputes over deductions. A disorganised archive turns a simple request into an emergency, while a well-kept archive makes every check immediate. This guide explains which documents to keep, how to organise them, and how to ensure continuity of the archive when the administrator changes.
Which tax documents to keep
The core of the condominium's tax archive is made up of the documents that prove expenses, payments and obligations to the tax authority. These include supplier invoices, the electronic receipts of the F24s paid, the single certifications issued to suppliers and copies of the return forms. To these is added the documentation of eligible works, particularly delicate because it supports the individual owners' deductions.
For interventions giving the right to building bonuses, the archive must keep, in a linked way, the invoices, the traceable transfers, the plan for splitting expenses among owners and any authorisations or communications required by the intervention. It is the consistency between these documents that makes the deduction defensible in the event of a check.
- Supplier invoices and their recording
- Electronic receipts of the F24s paid
- Single certifications issued to suppliers
- Traceable transfers and documentation of eligible works
- Expense allocation plans and the minutes approving them
How long to keep them
The guiding criterion for the retention period is that documents remain available throughout the period in which the tax administration can exercise its checks and in which owners may be called to document the deductions claimed. Since building deductions are spread over several years, the documentation of eligible works must be kept for a long span, covering all the years of use and the subsequent assessment terms.
In practice it is advisable to adopt a prudent rule and not dispose of documents until it is certain that no check or dispute can any longer concern them. Destroying an invoice or a traceable transfer too early can mean no longer being able to prove an expense that an owner is still deducting, with consequences that fall on them and, indirectly, on the administrator.
How to organise the archive
An effective archive is organised by condominium, by year and by document type, so that every check is immediate. The soundest logic links each document to the corresponding accounting entry: the invoice to the payment, the payment to any withholding, the withholding to the F24 by which it was paid, the F24 to the supplier's single certification. This chain of links is what allows a position to be reconstructed in a few minutes.
Digital retention, if orderly and supported by a reliable system, offers clear advantages over paper: immediate search, lower risk of loss and continuity in handovers. The important thing is to maintain the integrity and legibility of documents over time, with regular backups, rather than relying on scattered folders without criteria.
Continuity across handovers
The most critical moment for a tax archive is the change of administrator. The outgoing administrator must hand over to the incoming one all the accounting and tax documentation of the condominium: without it the new administrator cannot correctly fulfil communications such as Section AC or the transmission of bonus data, while remaining responsible for the year in which they are in office at the end of December.
Formalising the handover with a detailed list of the documents transferred protects both parties and the owners. A well-kept digital archive makes this passage almost automatic, because the condominium's tax history is already structured and transferable, instead of being scattered in physical binders to be reordered.
The role of an integrated digital archive
Keeping documents and accounting together in the same system eliminates the distance between the recorded data and the document that proves it. When every invoice, F24 and certification is associated with its entry and stored in a structured way, responding to a check request or preparing an annual communication becomes a simple extraction.

Frequently asked questions
Which of the condominium's tax documents is it most important to keep?
The documents that prove expenses, payments and obligations to the tax authority: supplier invoices, electronic F24 receipts, single certifications issued to suppliers and copies of the return forms. Particularly delicate is the documentation of eligible works, because it supports the individual owners' deductions: invoices, traceable transfers and allocation plans must be kept in a linked way. It is the consistency between these documents that makes a deduction defensible in the event of a check, so none of them should be neglected or archived in a confused manner.
How long must I keep the documentation of eligible works?
The criterion is that documents remain available throughout the period in which the tax administration can exercise checks and owners may be called to document the deductions claimed. Since building deductions are spread over several years, the documentation must be kept for a long span, covering all the years of use and the subsequent assessment terms. The prudent rule is not to dispose of documents until it is certain that no check or dispute can any longer concern them.
Is a digital archive better than a paper one?
An orderly digital archive offers concrete advantages over paper: immediate search, lower risk of loss and continuity in handovers. The point is not digital versus paper as such, but the order and reliability of the system. A digital archive scattered in folders without criteria is no better than disordered binders. You need to maintain the integrity and legibility of documents over time, with regular backups, and link each document to the corresponding accounting entry, so as to reconstruct every position in a few minutes.
What must I hand over to the new administrator when I leave the role?
The outgoing administrator must hand over to the incoming one all the accounting and tax documentation of the condominium: invoices, F24 receipts, certifications, traceable transfers, allocation plans and documentation of eligible works. Without these documents the new administrator cannot correctly fulfil obligations such as Section AC or the transmission of bonus data, while remaining responsible for the year in which they are in office at the end of December. It is advisable to formalise the handover with a detailed list of the documents transferred, to protect both parties and the owners.
How do I make it immediate to retrieve a document in the event of a check?
The key is to link each document to the corresponding accounting entry and organise it by condominium, year and type. If the invoice is associated with the payment, the payment with the withholding, the withholding with the F24 and the F24 with the certification, reconstructing a position takes a few minutes. A management platform like AmministraPro archives and links tax documents to the accounts with search by condominium, year and type, so the proof of expenses and obligations is always at hand, without having to search among separate folders and binders.
