Hi ladies,

Just wondering if anyone can help me understand.

We recently done my husbands tax, 4 years worth of. I have just received the latest 09/10 NOA back and centrelink paid my supps and what was owing.
We over estimated by quite a bit for the other years, when they eventually get around to doing our refund/ NOA at the ATO (which Im not expecting for a while), does the FAO still be advised and will they have to back pay me for those years that we over estimated or does it not matter now as the years have already come and gone and we missed out?

Also does anyone know if the previous years will be treated the same as last financial year as in timeframe or does that get put on the bottom of the pile? Maybe its obvious seeing I did already receive the 09/10 NOA huh?
I don't know all the ins & outs, but I'm pretty sure you have a certain time frame to lodge your return in order to receive top ups. Might not be the same year, but the one after?

ETA - Found it! Factsheet (it's on page 9, top left paragraph)
If you overestimate your actual family income and are underpaid during the year, your Family Tax Benefit or your Child Care Benefit will be topped up to your full entitlement after the end of the financial year. For this to occur, you and / or your partner must lodge your income tax returns within two years of the end of financial year for which you are claiming. Topups may be used to repay outstanding family assistance overpayments.
