For the tax year just gone, I had an ABN as I was a manager for a party-plan thing. My income was less than the $6000 threshold so I shouldn't be paying tax. However, when I get to the summary screen (i'm using e-tax), I have to pay a small amount (and by small I actually mean miniscule). I'm not bothered about paying it, its just I don't want it to mess up my family assistance. Surely if my income was under the threshold, I shouldn't be paying anything?
And also, if I put in my aggregated/annual turnover, what is classed as allowable deductions? I left this blank so not sure if that's whats messed up things.

Any help in getting my head around this greatly appreciated!
