Some of you seem to think that Double Taxation Treaties are a mechanism whereby you can, as an individual, avoid paying tax.
Double Taxation Treaties are conventions between two countries that aim to eliminate the double taxation of income or gains arising in one territory and paid to residents of another territory. They work by dividing the tax rights each country claims by its domestic laws over the same income and gains. Over 1,300 Double Taxation Conventions exist world-wide. The UK has one of the largest networks with more than 100.
Nowhere in these treaties is the principle that anyone is exempt from tax, simply that they will notr be taxed twice.
I have to tell you, yet again, that just because you are a pilot makes no difference to the fact that you have to pay tax. You can cite the case of mariners but even they pay tax, somehwere. The only difference is the amount you pay.
If you live in Berlin, fly out of SXF and work full time for ezy, then you are liable for tax in Germany. There is no way out of this fact. If you believe differently, be prepared for a shock and a big tax bill.
