When you finalise the declaration, the final screen immediately displays a receipt: proof of the Limosa-1 declaration.

If you are not in a position to present it, your client is under the obligation to notify the Belgian authorities.

The proof of the Limosa-1 declaration includes a QR Code which allows you to easily register individuals carrying out construction work in Checkinatwork. Since 14 April 2015, the QR Code also contains the most important data from the Limosa declaration.
