Declaring is simple if you know what, when and how

The reporting obligations of Directive 2019-04 rest on a simple rule: every significant sale made by an operator is declared within thirty days. But you still need to know what is "significant", who declares and through which channel.
This page answers these questions, presents the content of a declaration and indicates the consequences of lateness or omission.
It is aimed at operators, but also at private individuals who sell through them.

What must be declared
Sales made by an operator above the threshold for its category are to be declared: €1,000 for online sales, €5,000 for gallery sales and €2,000 for auction sales. Sales below these thresholds are counted together.
The declaration includes: the operator's identifier, the date, the description of the work (with its OIMAP number if registered), the price excluding fees, the fees, the currency, and the buyer's and seller's countries. The identity of the parties is kept in the register but not transmitted.



Declaration channels
The main route is the Desk portal, which offers a simple form, data import from a spreadsheet and an automated interface for the most active operators. A paper declaration remains possible in States whose administration is not yet connected.
A receipt is issued for each declaration. It is proof that the obligation has been met and must be kept with the sale file.
Declarations in the service of statistics
Declarations are the basis of the Observatory's statistics. Without them, neither the world index, nor the top 10, nor the reports on regions and segments could be produced. Each operator thus contributes, by an administrative act, to a common information asset.
The Observatory sends operators a personalised dashboard that compares their sales with those of their segment. This appreciated return encourages punctual declarations.
Thresholds and deadlines by type of sale
| Type of sale | Declaration threshold | Deadline |
|---|---|---|
| Auction sale | €2,000 | 30 days |
| Sale in a gallery or by a dealer | €5,000 | 30 days |
| Online sale | €1,000 | 30 days |
| Private sale through an intermediary | €5,000 | 30 days |
