Despegue, you are somewhat misguided, I'm afraid.
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.
Quite simply, if you live and work in Germany, that's where you pay your taxes. If you have a home and family in Holland then you can probably elect to pay taxes there. But you are obliged to pay tax somewhere. There is no way around it. If you are not paying tax somewhere, you are breaking the law. If and when you are caught, you will pay all the back tax, and up to 100% of the unpaid tax in penalties. If the amount is large or uncollectable, you might even face prison. Recall Boris Becker and Michael Schumacher, both of whom narrowly avoided prison.
