Hi I have been living and working in France since July 2007. I buy and sell vintage clothes and small art deco objects etc or anything my clients might want. I registered and started paying the usual fees. I was on micro and did not need a accountant but because of not being a French speaker and knowing the system took one anyway. I paidf 2 payments to RSI, and ursaff every month. I have just had a demand for 10.000 euros as they said I did not pay RSI and I certainly did not kniow I should have been paying I heard nothing from the accountant or RSI for 3 years. I am now very worried as I do not have the money to pay as I am a small enterprise and just earn enough to survive. I am paying RSI now but its the back payments that they are demanding. Can anyone advise please I am very worried.
