Four steps and a bot check
OCAS's e-démarche has four steps: «Employeur», «Personnel de maison», «Personne de contact», «Terminé». The first page asks for your own AHV number, your date of birth, your civil status and since when, and your bank details. A bot check comes before the next page.

Annual invoice, source tax for everyone
According to OCAS, the simplified procedure differs from the ordinary one on two points. Source tax is collected for every employee, whatever her nationality. And invoicing is annual only.

Already registered: a different e-démarche
For employers already registered who are switching to the simplified procedure, with or without LTN+, OCAS has a separate e-démarche: «Procédure de décompte simplifiée (LTN)». A household that is just starting uses the registration questionnaire for employers of household staff.
