Child Benefit rules are the same in Wales as elsewhere in the UK. You can usually claim if you are responsible for a child under 16, or under 20 if they remain in approved education or training; only one person can receive it for each child. Your income and savings do not normally prevent a claim, although a higher-income tax charge may apply depending on your circumstances. Check the latest eligibility rules and make a claim through the official GOV.UK Child Benefit service, as HMRC makes the final decision.
