I'm changing our FTB into fortnightly installments from the lump sum. We've always claimed it through DH.

We haven't claimed our lump sum for the 2012-2013 financial year yet as his tax return is being checked over by the ATO (nothing sinister, just had a problem accountant).

If I am now claiming for that with centre link, do I still need to wait for his tax return?

And if I claim for the 2012/13 financial year, do I receive a lump sum back payment and then it rolls into fortnightly installments, or do I need to wait for the next tax return to be done and then start the ball rolling on the fortnightly repayments for the 2013/14 financial year?
