Launching your Startup in Luxembourg: Complete 2026 Guide
To launch a startup in Luxembourg in 2026, begin by choosing a SARL-S (from €1 in capital) to get started quickly, then migrate to an SA or SAS as soon as you plan to raise funds or set up an employee share plan. Luxembourg has a complete startup ecosystem: active incubators (Lux Future Lab, Technoport, LIST), the Fit 4 Start programme, an IP Box regime at an effective tax rate of 4.99%, and facilitated access to European investors.
Choosing the right legal form for a startup
For a startup at the seed stage, the SARL-S allows you to start quickly with minimal capital. As soon as the startup plans to welcome investors or set up an incentive plan (ESOP/BSPCE), it is advisable to migrate to an SA or SAS.

Favourable tax regime for innovation
Luxembourg offers an attractive IP Box regime: income from eligible intellectual property (patents, software, know-how) benefits from an 80% exemption on IRC (corporate income tax), i.e. an effective tax rate of around 4.99%. This regime attracts many tech and biotech startups.
Obtaining the business permit
For regulated activities, a business permit (autorisation d'établissement) issued by the Ministry of the Middle Classes is required. It certifies that the manager has the required qualifications and that the company meets the integrity (honorabilité) conditions.
