Child Benefit rules are the same in Wales as in the rest of the UK. You may be able to claim if you are responsible for a child under 16, or under 20 if they remain in approved education or training; usually, only one person can claim for each child. You do not have to be the child’s parent, but the child must normally live with you or you must contribute towards their upkeep. Higher-income households may have to repay some or all of the benefit through a tax charge, so check the latest guidance on GOV.UK.
