I've always been of the understanding that my employer withholds tax from my gross pay on the basis of 1) an estimate of the tax I'd have to pay and 2) whether I have a HELP/HECS debt or not.
I can see on my fortnightly payslips that an amount is withheld for tax, and an additional amount is withheld because I have a HECS debt.
Now doing my tax return, I've learnt that if your 'HELP repayment income' is above a certain level, then a certain percentage of that income amount is applied to further pay your HELP/HECS debt.
A table for next year can be found here (don't know where the current year one is):
I just wanna know, why the hell do they do it like this?? They already take some from my fortnightly pay, and now they take more based on this thing called my repayment income?! I thought that was the exact reason they withheld it from my fortnightly pay - to ensure I'd pay enough by tax time.
Anyone know more about this?
