What is the basic element of tax credit they say if you get more than you may get maternity grant?? Is that the £10 (got that up until I finally 10 months late told them my part time wage) a week one (for a child over 1) I'm getting £19 a week so wondering if I may be entitled to maternity allowance this time?? and if so when can I apply. guessing can oly apply once so if there is a chance I won't get now may wait till I'm on SMP only and they taking my wage as £13 a week! as tax credit may go up again, when can u apply I know its up to baby being 3 months but what about while pregnant?
