Hi Mimi, I wonder if you can advise me as I'm a bit worried about my situation regarding tax. I've just arrived in Canberra to start a new job at one of the universities here. My contract actually started back in October, when I came out for two weeks, but I was then put on unpaid leave so I could have time to take care of some stuff back in the UK. When I saw my salary paid into my Westpac account for those two weeks, I realised it was much lower than I expected and after several emails back and forth with payroll and HR, I realised that I was being charged the top rate of tax because I hadn't supplied a TFN. I've applied for this now that I'm in Canberra so the TFN should arrive some time this month. Looking at other sites online, I get the impression that because I missed the 28-day window to supply a TFN to my employer, they will continue to tax me at around 50% and that I can't apply for a refund until the end of the financial year, i.e. June. Have I understood that right? Or is it the case that if I give my employer my TFN later this month, that the tax rate will change immediately? I'm a bit confused and worried, as I'm looking at various rental properties this week but suddenly not sure I can actually afford to live here, if my salary has effectively been halved...! Any help would be greatly appreciated.
