UK Taxes
As an example I'd suggest a gross salary of £45-55k for light twins.
£45k p.a. = £3,750 pcm, the tax man then takes:
-£784 for PAYE tax and -£280 for National Insurance.
Take home pay is £2,686 pcm (based on typical tax coding)
However your employer pays an extra £425 in tax for you out of his own pocket - lucky him or her!
£55k p.a. = £4,583 pcm, the tax man then takes:
-£1,117 for PAYE tax and -£289 for National Insurance.
Take home pay is £3,177 pcm (based on typical tax coding)
Your employer pays an extra £531 in tax for you out of his own pocket.
Salaries vary widely and reflect your expereince, location of the posting and the type of flying (Charter/Police/Training etc) also it depends how much the employer will throw at your future training and keeping you current (Aircraft types and VFR/IFR/Night etc).
I hope that helps!
