Is there anyway of finding out what tax credits I would be entitled to from next April, I am thinking of not returning to work after maternity leave but need to know if its affordable, I am due back in March but have to give 6 weeks notice meaning I would have to let them know In january, so need to do some number crunching early on as dont want to be in sh*t street! I have done the calculator on money for mums but how accurate is this for next year?
