Child Benefit in 2025–26
Child Benefit is a tax-free payment made by HMRC to the parent or guardian responsible for a child under 16 (or under 20 if in approved education or training). It is not the same as CMS child maintenance — it is a government benefit paid regardless of whether parents are together or separated.
The 2025–26 weekly rates are £26.05 for the eldest child and £17.25 for each additional child. These rates typically increase each April in line with inflation.
High Income Child Benefit Charge (HICBC)
The charge is based on the higher earner's adjusted net income, regardless of who claims the benefit. Since April 2024, the threshold increased from £50,000 to £60,000, and the full clawback point moved from £60,000 to £80,000.
Child Benefit After Separation
After separation, only one parent can claim Child Benefit for each child. This is usually the parent the child lives with for the majority of the time (the "resident parent"). If the child spends equal time with both parents, the parents must agree between themselves who claims; if they cannot agree, HMRC will decide.
Importantly, Child Benefit payments protect your National Insurance (NI) record — each week you receive Child Benefit while a child is under 12, you receive an NI credit. This protects your state pension entitlement. Even if the HICBC means you would receive nothing net, you should still register for Child Benefit and elect not to receive the payment, to preserve your NI credits.

When to Consult an Independent Financial Advisor
Consult an Independent Financial Advisor (IFA) or tax adviser if your situation involves: income near the £60,000 HICBC threshold where pension contributions could reduce your adjusted net income; shared care arrangements where both parents want to claim; a custody dispute affecting who receives Child Benefit; or questions about NI credits and their impact on your State Pension entitlement.
