HMRC have asked for a business mileage log for 2015/16 for a client who has used vans throughout the year (and his 2 employees have too).
He hasnt kept a log as all of the mileage, he assures me, was for business hence all fuel claimed was for the business.
He does have another vehicle for private use (as do his employees who left the vans on site when not working).
Was a log still therefore necessary? Do we need to go back and list all trips to prove that all mileage done was for business?
Or is it just sufficient to say that all fuel was for business use in the van?
Thanks in advance
