Step by step: Launching your business as an SARL-S

A simplified limited liability company, also known as an SARL-S or even “1 euro SARL,” is a variant of the “conventional” SARL and has been available in Luxembourg since January 2017. It is ideal for those getting into entrepreneurship for the first time, offering a reassuring legal framework and simplified formation costs. The SARL-S form is well suited to service and consulting-type business models, which tend to require little investment. The administrative steps involved are quick and specific.

Characteristics, advantages and limits of an SARL-S

Corporate purpose 

The purpose of an SARL-S must fall within the scope of the amended act of September 2, 2011 governing access to occupations in craft trades, business and industry as well as certain liberal professions. If a business falls outside the scope of activities provided by the Ministry of the Economy, it cannot, in theory, use the SARL-S form (healthcare, purely financial or educational professions, etc.).

Formalities for setting up

An SARL-S can be formed by means of a private deed, meaning without having to go through a notary. This cuts costs and speeds up the formation process.

Registering with the Luxembourg Trade and Companies Register – RCS, however, is mandatory (via the Luxembourg Business Registers portal). If you do not use a notary for the formation of your SARL-S, you will have to handle registration formalities yourself, online.

Minimum share capital

The share capital must be between 1 and 11,999 euros. Hence the “1 euro company”!

Targeted persons

This form is especially well-suited to entrepreneurs aiming to start or test a business activity that, by nature, does not require extensive start-up capital.

The SARL-S form is recommended for entrepreneurs looking at a simple business model. Someone starting a business alone, typically with activities in consulting or of predominantly intellectual nature, can also choose to start a “single member” SARL-S holding all shares.

By contrast, if you already know you will have high and recurring running costs (advance payments on rent, purchasing merchandise, specific material or equipment, etc.), like for a restaurant, for example, it would not be an appropriate form for your business.


The SARL-S form is intended exclusively for private persons, in such a way that an SARL-S cannot have a company as an associate. Furthermore, a private person can only be an associate of one SARL-S at a time (except when shares are transferred onto that person as the result of a death).

How much does it cost?

The administrative formation of a simplified SARL entails little cost: a 24 euro administrative tax for the business permit and 40 euros for electronic filing with the LBR.

Though incorporation is uncostly, accounting principles and obligations relating to the SARL-S form are identical to those for a “conventional” SARL. Look into costs relating to your accounting requirements to get a clear idea of what to expect in terms of annual fees. It is strongly recommended to use the services of an accountant due to the specificity of accounting standards for a capital company such as an SARL-S.

Annual expenses cannot be determined precisely and can greatly vary depending on your line of business, the size of the company, etc. Usually, the amount is several thousand. As an indicator, often between 2000 and 5000 euro. Among such expenses, keep in mind the annual fees for the relevant professional Chamber, wealth tax (minimum fee of €535 to be paid regardless of the company’s net earnings or loss), as well as accounting and banking fees.
