Was just thinking about this tonight so haven't had the chance to phone and ask for information so thought I would see if anybody here knows 
I receive child tax credits for my baby (not working tax credit as I am on unpaid maternity leave therefore not classed as working).
I go back to work in the summer and I expect to earn £20k+ in tax year 2014/2015 therefore get little if any tax credits.
Does this mean that while I don't receive a wage I will get the very small amount of tax credits only?
They are assessing the credits I receive just now on my estimated income for 2013/2014 and I am getting a good amount because of my reduced wage (enough to help support me alongside my savings).
