Tax evasion, the act of using illegal methods to minimise the tax you pay, is illegal.
Tax avoidance, the act of working within the law to minimise the tax you pay, is legal. In fact, it is not only legal, but both morally and fiscally responsible.

Nice to see that they’re proving my point: government should be given the minimum money possible lest they waste it doing stupid things like this…
