Hi there, Last FY I received two Pay summaries from my one govt employer. I was seconded to another role part time but still had the same bosses and only working a total of a 40 hour week. As a result of this I received two summaries at end of year and was met with a hefty tax bill and did not utilise any voluntary tax payments. So my question is, can I dispute this bill with the ATO in order to reduce my bill as I believed I was still with the same employer? Many thanks.
