Sadly, my experience in France (as an invited foreign entrepreneur) has been nothing️ like this.
Business matters are super expensive for sure. Eg, bookkeeping starts at €350 a month (I don't pay €350 a year in other countries). Administration is over the top. Another example, there are 145 lines of information required to send on each salary, every month to the authorities. And none of the affordable accounting systems have integration with the tax authorities so you have to spend weeks debugging tiny amounts of irrelevant information to upload files in their specific formats. Most payroll processing system are €100 a month person understandably for the obsolete. By law you even need to keep electronic copies or receipts︀ as pdfs for 50 years, stored on a French file server, with time stamped data︁ entry logs!
The staffing subsidies do exist, and some are quite good. but take 6︂ months to arrive. Again not within the promised 6 weeks. Banking is relatively expensive too︃ . Online government support and services are a lot smaller in France than other EU︄ countries. There is a strong tendency to try to get you on the phone. As︅ I don't speak French we hired a local business manager to do this and even︆ he found the system way too cumbersome. The tax office is either aggressively attacking you︇ or friendly as hell. I had to threaten them with another letter to Macron if︈ they didn't remove the €1800 penalty they hit me with for being late with our︉ first €0 payroll report (that couldn't be lodged as they couldn't even open an online︊ account for us)
After dealing with the fiscal authorities together with the immigration admin (18︋ months instead of the promised 2), health system complexity, even swapping drivers licenses took 2︌ years (and still no proper motorcycle license), we cut our losses, sacked our local staff,︍ and moved our operations outside of France. I still maintain a company there for now,︎ but it does very little. It is quite useful in Europe to have a European️ company though.
We plan to use a tech savvy, English speaking country (maybe Ireland or Malta) for lodging our non-treaty taxation reports in the future.
As a digital nomad I'm rarely in France anyway so the personal taxation issues aren't a major consideration.
I agree that French taxes are pretty much in alignment with many OECD countries, but the admin overhead is over the top for me.
