I am a non-eu student. I have a PhD admission from a French university where the funding will come from an institution at my country (outside of the EU) who will pay me directly.
My question is the monthly stipend that I would receive will be taxable in France? If yes, how do I find out which bracket I am in?
This question is similar to Are PhD scholarships and assistantships taxable?, however it is specific to France’s case.
As far as I know, the source of funding and your nationality are irrelevant with respect to taxation. You will be a French resident because you will be living in France, I assume, and you will thus be taxed on your income. (There may be an exception if your stipend is taxed in your home country and France has signed a treaty with your country to prevent double taxation. This is a rather niche case.) This webpage has a lot of information about taxes when you are a student: https://www.etudiant.gouv.fr/fr/impot-sur-le-revenu-le-cas-des-etudiants-1837 In short, very few sources of income are tax exempt. A salary for working as PhD student is not part of it.
The tax brackets are available here: https://www.service-public.fr/particuliers/vosdroits/F1419 note that the tax rates shown are the marginal tax rates, not the total tax rates. There is also a simulator available there, in case you have other sources of income to declare and would like a comprehensive assessment: https://simulateur-ir-ifi.impots.gouv.fr/calcul_impot/2022/index.htm
