This is definitely a simple tax calculator that can help you a lot. You can use this calculator in finding out your income if you have been provided with a new job or given an annual rate. This calculator is also for you if you already knew your salary rate but have to calculate your annual income. It doesn’t consider the 100 or so questions a tax advisor would inquire, but provides a basic PAYG assumption based on the current Australian Tax Office tax tables. Just enter your salary and it will routinely compute so that you’ll know your tax.
