It is possible that Osborne is telling the truth about his tax arrangements although he is very economical with it usually.
Income from his company would be subject to 42.5% Dividend Tax
Income from selling his house would be subject to Capital Gains Tax
Perhaps he can offset his rental against mortgage payments made.
I dont really care how much he earns just care about how his economic plans are hurting me my family and the country his tax cutting is too austere
