Child Benefit is not a claim-and-forget benefit. HMRC expects to be told about changes, and it recovers money paid in error. Most overpayments are not fraud: they are the result of a change that was never reported, or reported late. The list below is the one to keep.

Changes you must report to the Child Benefit Office

Overpayments

Money paid after entitlement has ended, or paid at the wrong rate, is an overpayment, and HMRC recovers it. The usual cause is a reported change arriving late: a child who left education in June but was reported in October has been overpaid for the intervening months. Reporting promptly is therefore not bureaucracy for its own sake — it is the difference between a clean claim and a debt. If HMRC believes an overpayment has occurred, it will write with the amount and the recovery route; disputing the underlying facts (for example, the date a child left education) is a different matter from disputing that overpayments are recoverable in principle, which they are.

Payment day and weekly payment

Child Benefit is usually paid every four weeks, on a Monday or Tuesday. Weekly payment is available instead for single parents and for people receiving certain other benefits, such as Universal Credit. Weekly payment is a choice to request, not an automatic entitlement for everyone, and it is paid on a Monday or Tuesday each week. GOV.UK does not assign payment days by National Insurance number, and this site does not either.

Reviews

HMRC reviews claims from time to time, and may ask for evidence that a child remains in approved education or training, or that the claimant remains responsible for the child. A review is routine, not an accusation, but it is another reason to keep the claim's facts current: a review that finds an unreported change will produce an overpayment for the whole unreported period, not just from the review date.

Going abroad. GOV.UK's wording for time abroad is narrow — certain countries, or Crown servants — and this site does not go beyond it. Do not assume a claim continues abroad, and do not assume an 8-week continuation from a calculator site: check with HMRC before travelling, and report the move either way.
General information only. This page explains Child Benefit in plain English. It is not legal, financial, or tax advice, and it cannot decide whether you qualify. Only HMRC can decide a claim. Rates and rules change over time — the figures here are for 2026/27, from April 2026 — so always confirm the current position with GOV.UK or HMRC before you act on it.
