Compulsory super is not a tax but a money paid to employees in lieu of wage rises. So it is part of an employee's wage not a tax.
As a small business owner too I'd suggest if your only taking $50k it isn't the government's fault.
I also know that I get some pretty good tax write offs through my business that i had no access too years ago when I had P.A.Y.E. tax payer. Car, petrol, phone, home office, travel, etc etc.
Stop the whining. I can't stand the whining of small business people. If you don't want the risk get a job. Your rewarded for taking the chance is potential high rewards. Don't give me this Cr--p about worthwhile community service. "Some recognition" give me a break - what do you want a medal? All I want is the money I make.
