Practical regulations
Issuing tax certificates to residents
Every year, ahead of tax filing season, residents who incurred deductible expenses through their building, such as renovation, energy efficiency, or seismic upgrade works, need a clear document certifying their individual share of the cost. This task falls on the property manager, who must reconcile the cost allocation plan with the invoices the building actually paid and hand each owner a certificate that is accurate, traceable, and consistent with what tax authorities may later verify. A mistake at this stage, or a late delivery, becomes a personal tax problem for the resident, not the manager, which is why the documentation process needs to be set up correctly from the start of the works, not reconstructed at year end.
What the certificate must include
The certificate is not a free form document: it must let the resident, or their accountant, correctly report the figures on the tax return and withstand a possible audit. It should clearly state the building's identifying details, a description of the works and their qualifying nature for the deduction, the total cost paid by the building, the ownership share or the specific allocation criterion applied to that particular intervention, and the individual share attributed to that resident.
That individual share must match exactly what was approved in the annual financial statement. If the allocation followed a criterion different from the general ownership shares, for instance an elevator cost split under the specific rule for shared equipment used unevenly by different floors, or works on a common part used only by a limited group of owners, the certificate must reflect that specific criterion rather than a generic ownership share table.
Linking certificates to invoices and traceable transfers
Most building related tax deductions require payment through a dedicated bank transfer that records the purpose of payment, the tax code of the party claiming the deduction, and the tax identification of the contractor who carried out the works. When the building itself makes the payment, the manager must keep records linking every transfer to its invoice and to the specific work authorized by the owners' meeting.
The certificate issued to each resident should therefore be traceable backward: from the individual share, to the overall invoice, to the transfer that settled it, back to the meeting resolution that authorized the expense. Keeping this chain organized throughout the year, rather than reconstructing it close to the filing deadline, sharply reduces errors and processing time.
Delivery deadlines and the manager's responsibility
Certificates need to be ready early enough for residents to hand them to their accountant before filing their tax return. A delay by the manager does not excuse an incomplete tax return, but it can expose the manager to complaints and claims for damages if the delay actually prevented a resident from claiming the deduction for that tax year.
For this reason, it helps to set an internal deadline ahead of the tax filing deadline and communicate it together with the annual financial statement, so residents who need the document know when to expect it and can flag any discrepancy in time, before it becomes a problem on their tax return.
Managing multiple buildings and overlapping works without errors
The practical difficulty grows with the number of buildings under management and when several different works overlap in the same building, sometimes under different allocation criteria. Keeping the share calculation separate for each intervention, with a clear reference to the relevant resolution and the allocation criterion used, prevents the share of one job from being mixed up with another.
Management software such as AmministraPro, which links the cost allocation plan, the approved financial statement, and the supporting expense documentation directly, allows certificates to be generated for each resident without manually rebuilding every connection, and keeps a stable record for the following years in which the same deduction still needs to be reported.
Frequently asked questions
Who is responsible for issuing tax deduction certificates to residents?
The property manager is responsible for preparing and delivering to each resident the certificate for deductible expenses paid by the building, showing either the general ownership share or the specific allocation criterion used for that particular intervention. If the building has no manager, the task falls to whoever handled the payments on behalf of the owners.
Must the certificate always use the building's general ownership shares?
Not always. If the works concern a common part used by everyone under ordinary criteria, the general ownership shares apply. If instead the works concern equipment such as stairs or elevators, which are allocated based on actual use, or common parts serving only a limited group of owners, the certificate must reflect the allocation criterion actually approved at the owners' meeting for that intervention, not a generic ownership share table.
What happens if the manager delivers the certificate late?
A delay does not exempt the resident from correctly reporting the expense, but if it effectively prevents the resident from claiming the deduction in the correct tax year, it can expose the manager to complaints and claims for damages from the affected resident. It is therefore advisable to set an internal deadline ahead of the tax filing date and communicate it together with the annual financial statement.
How do you avoid mixing up shares when several works happen in the same year?
By keeping the share calculation separate for each intervention, with a clear reference to the specific resolution and allocation criterion used for that job. Property management software such as AmministraPro automatically links the financial statement, the allocation plan, and the expense documentation, reducing the risk of overlapping shares from different works.
Is the certificate also needed for deductions spread over several years?
Yes. Many building related tax deductions are split into equal annual installments over a period set by law. The initial certificate, and the documentation supporting it, must remain available and consistent for the entire duration of the deduction, since the resident will need to report the same share again in every following year.
