based on your incomes this year, you'll probably be on minimal if any til july 1 - from then, i'd do the estimate on you nil, your partner 50 - BUT, if you're likely to go back to work, incorporate your income into partners or you will end up with ftba overpayment.

when you return to work, lower dh's income estimate and put that income against yourself - it's complex but it works i promise!
