If we handle corporate accounting, we can also take care of private accounting if you wish.

We have an excellent knowledge of Swiss taxation of individuals and companies at federal level (DFI, withholding tax, VAT, etc.).

In terms of cantonal taxes, we have considerable expertise in the cantons of the Lake Geneva region.

As with all our activities, we don’t hesitate to call on our network to validate certain delicate points, or to request validation directly from the relevant authorities.

Yes, of course. We start by talking to the customer to define the objectives, means and scope of the business. The domicile of the founders and the existence of a sole proprietorship are also crucial at this stage in choosing the most suitable structure. Next, we draft a letter for a notary (chosen by the customer or from our network) to formalize the creation of the company. We can also advise on accounting, registration with social security bodies (AVS, LPP), loss-of-earnings insurance and VAT registration.

Swiss standards still require that accounting records be kept for 10 years, or even 20 years in the case of real estate, or that accounting records be digitized according to very strict standards, which require special software (Olico).

In practice, however, VAT controllers, for example, make do with standard PDFs, in our experience.

To optimize exchanges with our customers as part of our accounting services, we are increasingly using shared directories (Sharepoint) or, more recently, Deepbox, an intelligent mailbox serving as a platform for electronic exchange and automated document processing, enabling us to integrate accounting documents directly into our Abacus software. For the reasons outlined above, customers should nevertheless retain paper documents.
