So I've gotta call into centre link to declare our family income however I'm a little confused, do I give them his wages before his deductions or after...

He get's a living away from home allowance (taken from his wages before it's taxed), has to pay agency fee's to the company that invoice on his behalf, his super gets taken out of his wages before tax, and he may be doing the salary sacrifice for a leased car as he needs to be able to get around down in Canberra for his job.

Do I tell them the whole amount or just what he gets taxed on?

Just want to make sure I work it all out before I go in if I have to remove some of the things or all of them.
