The name is taken from the sky in a painting featured in the movie. The movie Vanilla Sky is a remake of the Spanish movie Abre los Ojos (Open Your Eyes) which is a really good movie.
If you use your own car for business, you will be able to claim 45 pence per mile for the first 10,000 miles, and then 25 pence per mile for each mile thereafter. These are tax free and known as Approved Mileage Allowance Payments (AMAPS).
The standard mileage rate for 2016 is 54 cents/mile. An employee can use the whole benefit if a company does not reimburse mileage at all. The taxpayer can deduct .54 of a dollar for every mile driven in his/her personal vehicle for business purposes (this does NOT include the commute to and from work!).
