Details supplied on the email. There was a contact number 

I was contacted by email and I called them and was informed a tax agent was looking into the expenses as they where high for my industry. Looking back I had over claimed by mistake. They paid a rebate into my account. I have no issue paying back anything that's over paid. What I'm worried about  if there's any penalties I'll have to pay ie fines or if it'll affect my Visa in any way. I'm not sure the best way to handle it. 

I've recently been contacted by the ATO for expense claims. I've realised I've made a mistake and over claimed on my tax return and can not find many of my receipts. Basically I've very little knowledge of the tax return system here. I'm I likely to receive any type of penalties or fines ?? Any information is much appreciated. Thanks guys!!!!
