Lan -Medecin Auto-entrepreneur

"Je payes une texe sur les revenus d'auto-entrepreneur que je declares tout les 3 mois à l'URSSAF. On me prélève environ 22,5 % de mes revenus. Je suis donc prélevé par l'URSSAF 4 fois par an. Ces taxes sont uniquement perçu sur mes expertises qui sont une activité annexe à mon métier de chirurgien. Cependant je déclare en plus annuellement tous mes revenus d'expertise aux impôts qui me taxent aussi sur cette somme.Je ne paye pas la TVA sur mes revenus d'auto-entrepreneur car je déclare moins de 34400€ par an ( c'est le plafond fixé par le gouvernement) "
