Unfortunately the questions being asked about tax are repetitive. Sadly this is a Pilot forum not an accountant or tax advisor forum. Each country will be different and each individual will be different depending on family size/status etc etc etc. Tax is individual and costly if you have the incorrect advice.
My suggestion is go and pay the fees you need to get professional tax advice and don't make the same mistakes at NAS that were made by Ryanair Pilots which are now resulting in home raids and tax bills in various countries across Europe. Hopefully the large amount of guys moving across from Ryanair have learnt their mistakes and will do things correct this time, rather then sit around waiting for all the answers delivered on a plate while doing nothing to help themselves.
Sorry if that is overly blunt. The gross figures are no secret but we have no input into your net figures - some guys can't claim expenses, others have creative accountants, others are on non-resident tax schemes, some even claim they are sole traders despite what it being clearly stated in their contract their are employees. The point is everyone is different and information on this forum is either individual specific or complete guesswork.
If one really wants ball park figures there options. Take the gross figures, which are no secret and use the calculators online for each country which allow you to enter your gross earnings and family status. I have found and used good calculators for Spain and the UK.
This is a very useful thread for information about NAS.
Don't let it derail into everyone asking what NET pay will you get in each base. If your already in the system talk with your agency.
Those weighing up moving from blue to red should also consider that money is not the only factor. You can not put a price on being treated like a human being.
