My corporate client has purchased, for a lump sum, 100 hours per year (8,760 hours) flying time in a private plane during the life of the plane . The plane's mv at time of this purchase was £5 million and the client has paid £700,000 for the flying time and will also pay annually the costs relating to the each flight, say £50,000 a year. An employee of my corporate client will be able to use the plane for private use. My initital thought was that the benefit (before any deduction for business use by any employees of my client) should be £700,000 x 20% = £140,000 + 50,000 = £190,000. It has been suggested to me that the legislation supports an analysis which takes (£5,000,000 + 700,000) x 20% = 1,140,000 x (100/8760) = £13,013 + £50,000 = £63,013 as the benefit. Views please?
