The micro-entrepreneur status is open to commercial, craft and certain liberal professions. However, some specific activities are excluded from micro-entrepreneurship:
To qualify for micro-business tax status, you need to meet the annual sales thresholds set for the 2023-2025 period:
An individual cannot run two micro-businesses at the same time. However, it is legal to combine two activities within the same entity. The auto-entrepreneur operates under the same business registration number. A single person can develop only one micro-business and have only one Siren number.
To develop a secondary activity as a micro-entrepreneur, you need to make a declaration on the guichet unique des entreprises website. There's a subtle difference between the two. You must declare which of your two activities is yourmain one. This is the one that generates the most sales. Your APE code and SIREN-SIRET number are based on the nature of your main activity.

If you have several activities, you don't need to make a separate declaration for each one. The declaration to be made is unique, and is done either on the website, or on the URSSAF application dedicated to auto-entrepreneurs. It is made monthly or quarterly, depending on the option chosen when you set up your micro-enterprise.
Three boxes are available:
If your activities are grouped together in the same category, you must enter thetotal sales achieved. If your activities are mixed, you must divide your sales between the different boxes.
The sales declaration is normally automatic if you have entered the correct amounts on the URSSAF website or application. If you need to retranscribe the amounts, here are the corresponding boxes on your tax return:
If you have chosen the prélèvement libératoire (withholding tax) option, the boxes to fill in are different:
