Practical regulations
The condominium single certification
When a condominium pays amounts subject to withholding tax to businesses and professionals, for example the property manager or contractors performing work under a service agreement, it acts as a withholding agent and must issue a single certification to each recipient of the withholdings applied during the previous year. This obligation falls directly on the property manager, who is responsible for calculating, withholding, remitting and certifying the amounts. This guide covers who receives the certification, the delivery and filing deadlines, what the document must contain, and how to organize records so the deadline does not arrive unprepared.
Who receives the single certification from the condominium
The condominium issues the certification to every recipient of amounts subject to withholding tax during the preceding calendar year. The most common case is the property manager, whose fee is subject to withholding when the role is performed professionally, either with a VAT number or as occasional self-employment above the relevant threshold. Businesses and professionals who performed work or services for the condominium also fall within scope, when the service qualifies as work subject to withholding rather than a simple supply of goods.
Not every condominium expense generates a withholding: supplies of goods, purchases of materials, and utility bills do not trigger the certification obligation. The distinction must be made case by case based on the nature of the contract, and in doubtful cases it is worth checking with the condominium's accountant before applying or excluding the withholding on an invoice.
Delivery and filing deadlines
The single certification has two deadlines. Delivery to the recipient must occur by March 16 of the year following the one in which the withholdings were applied, so that the professional or business has the document in time for their own tax return. Electronic filing with the tax authority follows the annual fiscal calendar, generally by March, and must be checked every year because exact deadlines are set by the tax authority's own provisions.
Missing the deadlines exposes the condominium, through the property manager who holds the managerial responsibility, to tax penalties. It is good practice to schedule the preparation of the certification well ahead of the legal deadline, allowing time to verify amounts, payment reasons and recipient details before filing.
What the document contains
The single certification reports the identifying data of the condominium as withholding agent, the recipient's data, the gross amount paid during the year, the withholding applied and remitted, and the reason for the payment. Each recipient gets a separate certification, and if several payments were made to the same recipient during the year they must be aggregated into one annual document.
A common error is certifying amounts that differ from what was actually remitted through the tax payment form, often because of a mismatch between the invoice issue date and the actual payment date: the withholding must be referred to the moment of payment, not of invoicing, following the cash basis principle that governs this obligation.
Document management in AmministraPro
Tracking every payment subject to withholding throughout the year, together with its reason and recipient, avoids having to reconstruct the data right before the March deadline. In AmministraPro, payments to suppliers and professionals stay linked to the related invoices and to the condominium's cash movements, so at year end the property manager can extract an orderly list of recipients and amounts to certify, reducing the risk of missing a position or duplicating an entry.
Having an organized history by condominium and by year is particularly useful for property managers handling multiple buildings: it turns the certification campaign into a repeatable task rather than an annual emergency, with the option to check at any time the features and plans available on AmministraPro for the condominium's accounting and document management.
Frequently asked questions
Does the property manager always receive the single certification from the condominium they manage?
They receive it when their fee is subject to withholding tax, which is typically the case for those who perform the role with a VAT number or as an autonomous professional service. In that case the condominium is a withholding agent toward its own property manager exactly as it is toward other professional suppliers, and must issue the certification by March 16 of the following year.
What happens if the condominium does not file the single certification within the deadlines?
Delay or omission exposes the condominium, through the managerial responsibility of the property manager, to tax penalties provided for withholding agents who fail to comply. It is advisable to plan the preparation of the certification with margin ahead of the deadline, verifying amounts and recipient details before the electronic filing.
Do all invoices received by the condominium generate a withholding and therefore a certification?
No. The withholding applies to work services subject to this regime, not to simple supplies of goods or utility bills. The qualification must be based on the nature of the contract, and in unclear cases it is best to check with an accountant before applying or excluding the withholding on an invoice.
How should document management for the certification be organized when a property manager handles several condominiums?
An organized history by condominium and by year is needed for payments subject to withholding, with the reason and recipient always linked to the related invoice. Tools like AmministraPro connect payments to invoices and cash movements, so at year end the list of recipients to certify can be extracted in an orderly way instead of being reconstructed manually condominium by condominium.
Should the withholding be calculated on the invoice date or on the actual payment date?
On the actual payment date, following the cash basis principle that governs this obligation. A mismatch between invoice issuance and the recipient's actual receipt of payment is the most common cause of certification errors, because the withholding and the related certification must be referred to the year in which the payment occurred, not the year the document was issued.
