@Julie5091I'm sorry to hear this. I can say two things with certainty:
- the Impots (French tax authority) stance is bizarre - surely you would want to draw in taxpayers at the earliest opportunity?
- no-one at AirBnB, including various moderators, was of any help whatsoever. Lots of warm words and "I'll look into to it" but it all came to naught.
Don't fight the fight. There's nothing to be done about the situation unfortunately.
I just carried on (weathering multiple emails from AirBnB as you did) and eventually the 'clock' ticked over and I got my numéro fiscal which I have now duly appended to my AirBnB profile.
It never interrupted my ability to rent out my house.
So that's what I suggest to you too. Just carry on. Cross your fingers, and hope for the best.
