We have one child, 8 months old. I earn just under £50,000 but my husband earns over. I claimed it as I was told it helped the child to automatically get NI registered when they were older and it counts towards my credits whilst off work. However, I am unsure as to how we pay back the % we owe. My dh is self employed so already fills out a tax return - do we do it on there even if the child benefit is registered in my name? We asked my husbands accountant who said not to worry because his net salary is not £50k but as I know that is incorrect I am reluctant to take her advice on anything else!
