The annual declaration

Annually you report to Valumat about the number of mattresses that you have brought onto the Belgian market via an online application. We call this the annual “declaration”.

Valumat expects the first declaration of the number of mattresses on the market in 2024 by March 31, 2025 at the latest.

For the following years, the deadline is always on March 31 of the year following the reference year. Then the actual quantities of mattresses on the market of the previous year are known.

Your declaration step by step

At the beginning of each calendar year Valumat sends you an invitation by e-mail to fill in your annual declaration with a unique code.
You follow the instructions to log into the application.
On the validation screen, you fill in the unique code and your e-mail address.
An automatic e-mail with a link is generated and sent to your e-mail address.
Then click on this link to fill in your declaration and follow the instructions on the screen.

Invoicing and payment

Invoicing contributions and payment terms 2025-2026

First invoice: the 2024 settlement*

In april 2025, Valumat sends a settlement of the past year (2024).
The settlement is the difference between the actual contribution for 2024 (see 2024 declaration) and the advances already invoiced and paid for 2024.

This invoice is payable within 30 days.

Three advance invoices 2025

Valumat sends three advance invoices for 2025 to the participants at the same time. The total advance financing is calculated as follows: number of mattresses placed on the Belgian market in 2024 multiplied by the rates of 2025.

The first invoice of 25% of the amount is payable within May 31 2025.

The second invoice of 25% of the amount is payable within August 31 2025.

The third invoice of 25% of the amount is payable within November 30 2025.

This means that each year participants only have to pay 75% of the advance financing due for 2025 in 2025. The balance of 25% will be settled in April 2026 together with the settlement for the year 2025. The 2025 settlement is the difference between the actual contribution for 2025 and the advances already invoiced and paid for 2025.
This ensures that the pre-financing for the participants is limited and that the totality of the VAT charged can be immediately recovered.
