So I got the letter that everyone else has got and it's saying that the amount I reported to Centrelink in the 2012/13 financial year was about $15,500 but the amount the ATO has me earning is $20,000. I have looked over my records and it appears that I did indeed earn $20,000 working casually while I was at uni. Genuinely fucked it up, I was obviously young and stupid as shit. Willing to hold my hands up and except responsibility for my stupidity.

Anyway, I have submitted it all online and it says it'll take 4 weeks for someone to review it. Can't really be bothered to think about it for that long. Does anyone know how much I'm going to owe Centrelink? Is it just a matter of them calculating and telling me how much and me paying it or doing a payment plan? Or will there be further consequences?

Thanks in advance.
