due to childcare and work issues i feel i need to give up work to look after my twins. I am married and worked out we would get about £100 p/w in child tax credit. My question is that this is based on my zero earnings in the tax credit calculator but if I don't give up work untill say July, would my earnings to date be added to my husbands in which case we would get virtually nothing. Surely its based on your current circumstances and now what you earned 4 months ago into this tax yr. Many thanks, I cant seem to find a striaght answer anywhere
