The one you get after you lodge your tax return. We have just lodged our tax return and wondering around about how much we will get back. I get both family tax a and b and have been paid the correct rate. I also have 3kids. My gearbox is my car completely wend and it's going to cost 3700 to fix with all the appointments I have for ds2 can't afford to go without a car unfortunately so wanting to get it fixed asap.
