One fact is that if you provided truthful and honest information you would not have received a letter.
In one word bovine excretment !
1. Say you are on Newstart for all of January and you have not worked at all during January and have correctly declared $0 income.
2. You are then employed as say a teacher on Feb 1, at say a a salary of 52k and all your income is correctly declared.
3. On 31 Jan you inform Satanlink you no longer require Newstart and receive no more payments from them..
So far you have met ALL obligations placed upon you by both Satanlink and the ATO and have done absolutely nothing wrong
Now 12 months later Satanlink performs the worst data match evah (divides 52k by 26 and comes up with an averaged 2k income per fortnight) - and thinks you have defrauded them and sends you a letter in which you are invited to 'correct' the problem. Which you then do - you go to aus.gov.au and you confirm that yes you did indeed earn 52k that year (the only number you are allowed to enter) then its THIEF THIEF THIEF ! YOU OWE US 1,570.40 !!!!!!!!!
At what point have YOU done anything wrong ? Only once have you given the government an interest free loan of 1570 are you allowed to appeal .
