customs and excise look on any “rental” is for 52 weeks a year if they are truly independent of the salon owner and no rent free holidays .also percentage deals are illegal as there is a tax liability issue here . You can build the rent free two weeks by your calculations over the 50 weeks . Remember the independent chair renter has to be totally free of the salon owner .
The hairdresser federation run work shops with customs and excise which I have attended for clarity re V A T .the main grey area is when you combine everyone in the salon there takings as a whole are over the v a t threshold but because they are independent no individual is over the £85000 be carful to this !!!!!
