Hi, This is my first year as C.I.S have previously been under an umbrella company and p.a.y.e. When i was working through a composite company(PAYROLL COMPANY) under the umbrella scheme i was able to claim mileage of 40p a mile for the 1st 10,000 miles.I understand under the c.i.s self-employed scenario i can still claim 40p a mile for usage of my car.I have made 10,000 business usage so far,so i assume i will receive £4,000 in a tax rebate but compared to other sparks this seems really high so i assume i've got it wrong????Can anyone confirm this,thanks
