Child Benefit rules are the same across Wales and the rest of the UK. You can usually claim if you are responsible for bringing up a child under 16, or under 20 if they remain in approved education or training. Only one person can receive Child Benefit for each child, and special rules may apply if the child does not live with you. Higher income does not usually end entitlement, but the High Income Child Benefit Charge may apply; check the latest guidance on GOV.UK for your circumstances.
