Yes. Since 2018, all students in a French school must pay CVEC to complete their enrollment or re-enrollment. This is a mandatory tax (100 €) that must be paid each academic year.
Students should go to this CROUS website to make the payment: https://cvec.etudiant.gouv.fr/
International students can find information on this document : https://students.skema.edu/wp-content/uploads/2019/11/CVEC_payment_process.pdf
