You can usually claim Child Benefit 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 Child Benefit for a child, and the child will generally need to live with you, although some exceptions apply. Your earnings do not normally prevent a claim, but a High Income Child Benefit Charge may apply if you or your partner has adjusted net income above the relevant threshold. Check the latest rules and thresholds on GOV.UK, as entitlement depends on your circumstances.
