I am not excited at all about paying taxes. But if any time the tax authorities become agressive and start enforcing their tax laws and you have commited tax evasion in the last 5 years... well you are at certain risk dont you think? Anyway at this stage is hard to predict how things are going to be in the next years, but looking at how the economy is and the socialist spending agenda of this new government there are some reasons not to be very optimistic
That depends on the will of the Government in that moment. If they need money to finance their policies why wouldnt they try to tax you? Assuming things will stay the same for ever is dangerous...
