This may be a dumb question, nonetheless... If my annual income including super is say $150000, and I want to calculate the amount of income tax payable annually on that $150k (for simplicities sake let's assume no other income and exclude medicare levy surcharge, etc) - is my assessable income for tax purposes considered to be $150k, or is it $150 - super @ 9% = $136.5k? I.e. if using the calculator in the link below, would I enter $150k as annual income or $136.5k? Income Tax Calculator - Yahoo!7 Money Matters Thanks for your help!
