Hi I'm single parent of 1 working 6.5 hours a week I was looking to go up to 16 hours and would have received £70 working tax credit a week. After arduous calculations conversations with council HMRC Jobcentre it looked clear I would be worse off doing 16 hours which I was gutted about Another single mum in my work place has two children and said when she worked 16 hours she got £180 working tax credit a week -no childcare element. I understand someone with more children would receive more Child Tax Credit but I'm flummoxed as to why someone with more children than I do received over double the amount of working tax credit I would get for doing the same job same hours does anyone understand these things and could explain please?
