It's all well and good to say tax is voluntary if you mean it in some philosophical, egoist, radical anarchist way but the fact is if you don't pay your taxes you could well go to prison or be .
When they say the tax system is based on voluntary compliance, they mean it in the same way laws against murder are. The government doesn't spy on you 24/7 to make sure you aren't killing anyone, they just expect you not to do it and only investigate if someone finds a dead body. Similarly, they expect you to be a responsible adult and pay the taxes you owe without having to be audited, but if you don't they'll take action from sending a polite letter to beseiging your house with armoured cars and snipers. I'm going to my student union advice centre to ask about how to deal with CGT events which aren't due to things already tied up with my TFN, and how to pay tax due on it (whether they'd just tell my boss to add more to my PAYG witholding for it or what.)
If you don't like paying taxes, either lobby for tax cuts or leave the country.
