Sure. Low (or even no) taxes on yearly income if you locate your startup well (e.g. put it in an area that gets subventions or tax cuts, checkout so-called ZFU aka Zone Franche Urbaine). If you're innovating (which is, really, an administrative term, that you can put anything under), you'll get tax rebate on the salary mass that you dedicate to R&D. Even further, your startup can be labeled as a 'young innovating company' (JEI, aka Jeune Entreprise Innovante) and you get even more benefits. I (with others) operate a startup with entities both in France and in the US. It is cheaper for us to leave R&D in France because of the subventions mentioned above. Sure, you'll still get plenty of taxes and the euro is strong, which may be good or bad depending on your activities. PM me if you need more details.
