In France, side income often comes from one-off gigs, selling items, local services, seasonal work or online tasks. This page shows SmartExtraLab ideas that apply in France, with the country filter already on. You can then refine by time, budget, season or tools you already have at home.
Each sheet covers how it works, usual steps and limits to know before you begin. For micro-enterprise, platforms, occasional sales or furnished rentals, see our rules guide: thresholds, declarations and special cases are summarised in general terms only. Nothing here guarantees income. Pick an idea that fits your schedule and energy, read the full sheet including warnings, then start small to check that the pace and the paperwork really suit you day to day.
80 ideas
The rules guide summarises caps and the micro-enterprise idea. It is not personal tax advice. Also read the sheet for your chosen idea (steps and warnings).
In many cases platforms send data to the tax authority. The rules guide explains the general idea (including DAC7). Keep your statements.
Yes: on this page, use the region filter (Île-de-France, Brittany, and so on) on top of France already selected.
