The sole proprietorship

La raison individuelle suisse

The sole proprietorship is a legal form where the individual carries on business in his own name and is personally liable in an unlimited manner. The owner may also be described as self-employed.

Simple to set up, it does not require any equity capital or formal creation. However, once gross annual sales of CHF 100,000 are exceeded, registration with the registre du commerce and VAT becomes compulsory.

This structure is ideal for entrepreneurs wishing to start up a small business or self-employed activity.

Opening a sole proprietorship

A sole proprietorship may be described as a natural person who carries on business in his or her own name and under his or her own responsibility.

The individual is personally and illimitatively liable for all his property and assets.

It is very simple to set up, as there is no formal act of incorporation; the sole proprietorship begins as soon as commercial operations are launched.

There are no capital requirements and no need to create a formal company or commercial contract.

Any individual can act as a self-employed person and set up an IR.

On the other hand, as soon as the sole trader achieves gross annual turnover of at least CHF100,000, he must register his sole trader in the Commercial Register (art. 36 para. 1 ORC).

How do you open a sole proprietorship?

Register with a compensation fund

The sole trader must be registered as a self-employed person with a compensation fund.

The compensation fund will check that the sole trader is self-employed and not employed by someone else.

A self-employed person may be employed by someone else for another activity, but not for the activity for which they wish to develop their self-employed activity.

On the one hand, the social costs paid by a self-employed person are completely different from those paid by an employee.

In addition, the compensation fund will ensure that an employer does not require an employee to register as self-employed in order to avoid paying social security contributions.

Registration with the Registre du Commerce

Entrepreneurs do not need to register in the Commercial Register as long as their annual sales do not reach CHF 100,000.
Below this amount, registration is optional but adds credibility.

If you run a business as a sole trader, you must include your surname, with or without your first name, in your company name (art. 945 para. 1 CO). No additions
suggesting a corporate link may not be added to the company name (art. 945 para. 3 CO).

The company name is protected by entry in the Commercial Register (art. 946 CO).

Domicile of the sole proprietorship

The registered office of the sole proprietorship does not necessarily have to be the same as the domicile of the sole proprietor.

Obligation to keep accounts

As a self-employed person, you will have to keep simplified accounts. However, if your turnover exceeds CHF 500,000, you will have to keep accounts in accordance with the Swiss Code of Obligations (art. 957 al. 1 CO).

VAT for sole traders

Sole traders are no exception in terms of VAT. Any natural or legal person whose annual turnover exceeds CHF 100,000 is obliged to withhold and remit VAT.

On the one hand, the self-employed person has unlimited liability for all his private assets and his business assets, unlike the SA or the LLC.

On the other hand, with entry in the commercial register, the self-employed person is subject to bankruptcy proceedings (art. 39 para. 1 par. 1 of the Federal Law on Debt Collection and Bankruptcy).

Frequent use of the sole proprietorship


The sole proprietorship is the second most common type of business.

The latter enjoys economic freedom, with a rapid decision-making process and no formal restrictions.

The sole proprietorship is often used to start up a small business or self-employed activity.


One of the main disadvantages of sole proprietorship, apart from the fact that it is often difficult to find the means to finance and sell the business, is that it is difficult to obtain finance.

What's more, it is often difficult to find the means to finance the business and pass it on to a successor.

The IR will have to be dissolved, as it is entirely linked to its manager, who has unlimited liability for all its private property and professional assets.

Finally, the name of the company cannot be chosen freely, unlike in the case of a limited company.


Sole proprietorship is an attractive option for starting up a business, but it carries with it specific obligations. Faced with these challenges, expertise is essential.
