Quick question, as from next month I will be working full time and DP staying at home. All the family tax benefits are in my name, do I need to put them in his name?
no - you just need to change the estimates to reflect your correct incomes

because ftb is a FAMILY payment, it can be paid in either name - it's actually better (less messy) to keep it in the one name all the time unless you change july 1
