You've gotta move abroad mate, a mate if mine lives in Belgium and commutes. His overall tax rate is comical, something like 0.2%. He can claim all sorts against his Belgium tax including commuting expenses and his mortgage interest.
In fact Belgium has one of the highest tax rates in the world (50%) Even after all possible deductions. Your friend benefits from a favorable double tax treaty, which doesn't allow Belgium to tax him altough he lives there. The Belgian-UK treaty has recently been changed because the old one lead to double non-taxation for pilots living in Belgium (UK) and working for a UK (Belgian) company.
