Our experience with Caisse AVS Valais

What we learned filling in the forms, from the office's own information and documents, and with our customers. Always with date and source.

Form tested
Page 1 is only the instructions
The «Questionnaire décompte simplifié Plus» has two pages: the first contains only explanations, and every field is on the second. At the top of page 2, tick «Déclaration d'affiliation en vue du paiement des cotisations», the box for a new registration.

Office documents
By post only
The office's e-business platform is not open to simplified-procedure accounts. A household therefore posts the signed questionnaire, and each year its wage declaration, to the office in Sion.

I already have accident insurance. Can I switch to the simplified procedure Plus?

Yes. The form reminds you that you must then cancel the old accident policy, respecting its notice period (AHV leaflet 2.07, section 7). A change of procedure only takes effect at the start of a calendar year (AHV leaflet 2.07, section 9).

My employee lives in France. Can I use the simplified procedure Plus?

No. The office's questionnaire says so, as does AHV leaflet 2.07: in Valais the simplified procedure is not possible if you employ cross-border workers who live in France. Because it must cover all your staff, the ordinary procedure then applies to all your employees.
