Manager's Expense Certificate for the Tax Deduction

For works on the common parts, the individual owner does not deduct the suppliers' invoices, but the share of expense attributed to them, as attested by the certificate issued by the condominium manager. It is the central document that links the condominium expense to each person's tax benefit. Without a correct certificate, the owner risks being unable to prove the deduction in the event of an audit, even if the condominium did everything properly.

Why owners deduct with the certificate, not the invoice

Invoices for works on common parts are made out to the condominium, not to the individual owners, and payments come from the condominium bank account. The owner bears the expense through the instalments paid, but is not the direct recipient of the tax documents. For this reason the manager, who acts under Article 1130 of the Italian Civil Code, serves as an information intermediary: they collect invoices and bank transfers, calculate each person's share according to the thousandths (millesimi) and issue a certificate that the owner uses in the tax return.

The certificate serves as proof of the expense incurred. The owner keeps it together with the condominium documentation and produces it only if requested by the tax authority; it is not attached to the return.

What the certificate must contain

There is no single mandatory template, but established practice requires the document to be complete and verifiable. Useful elements are:

• Condominium details (name, tax code) and manager details
• Reference year and a brief description of the work on the common parts
• The type of relief the work falls under
• Total amount of the expense and the allocation criterion (usually the thousandths)
• Share attributed to the individual owner and the amount actually paid during the year
• A statement that payments were made by a bank transfer suitable for the deduction

The relevant figure is the amount paid by the owner in the tax year, not necessarily the amount resolved. This distinction is decisive when instalments straddle two years or when an owner is behind on payments.

The role of thousandths in the allocation

Each person's deductible share follows the same criterion used to allocate the expense in the accounts, as a rule the general thousandths table or the specific one provided by Articles 1123 and following of the Italian Civil Code. The certificate must make this step transparent, so that the sum of the certified shares matches the total expense documented by the invoices. A discrepancy between the accounts and the certificate is the first sign that something is off.

When the owner has not paid in full

If the owner has paid only part of their share, the certificate must show the amount actually paid during the year, because that is what gives rise to the deduction under the cash basis. Amounts not yet paid may become relevant in the year in which they are actually paid. The manager must therefore keep accounts that link each payment received to the instalment and the work, so as to certify exact figures rather than theoretical ones.

The manager's responsibility

Issuing the certificate is part of the manager's reporting and transparency duties. A late or incomplete certificate exposes the condominium to disputes and the individual to losing the benefit. Good practice is to prepare it in good time, before the filing deadlines, and to archive it together with the work file, the contracts and the payment records.

Managing certificates in an orderly way

The certificate is reliable only if it rests on clean accounts: invoices linked to the work, traced bank transfers and a thousandths allocation consistent with the accounts. With AmministraPro the manager keeps expenses, allocation and documents together, so as to generate for each owner a statement of the shares paid without reconstructing the data by hand. The accounting and archive features are described on the /funzioni page, while plans for practices and single condominiums are on /prezzi.
