How to claim Child Benefit and handle the High Income Charge

Child Benefit is payable to someone responsible for a child under 16, or under 20 if the young person stays in approved full-time non-advanced education or approved training. There is no means test on entitlement itself, and no limit on the number of children, though the amount is paid at a higher rate for the eldest or only child and a lower rate for each additional child.

Only one person can claim for a given child. Where parents live apart, the person the child lives with most of the time normally claims; where the position is genuinely shared, the parents can agree who claims, and if they cannot, HMRC decides using a priority order. Two people cannot split one child's award between them, though with two or more children the awards can be split between parents.

Which parent claims matters more than most people realise, because the National Insurance credits follow the claimant. If one partner is working and paying National Insurance anyway and the other is at home with the children, the claim should be in the name of the parent at home — that is the one who needs credits. Getting this the wrong way round wastes the credits entirely, because the working parent's record is already being built through earnings.

This can be corrected. Where the credits went to the wrong parent, they can be transferred between partners for past years using the specific HMRC transfer route, and it is worth doing if you find you have years of credits sitting on a record that did not need them.

Residence and immigration status affect entitlement. You generally need to be present and ordinarily resident in the UK and have a right to reside, and most people subject to immigration control with no recourse to public funds cannot claim. There are exceptions, including for refugees and some people with pre-settled status, and claiming when your visa prohibits public funds can affect future immigration applications. If your status is not straightforward, take advice before claiming.

The claim also matters for the child. A Child Benefit claim made for a child normally triggers automatic issue of their National Insurance number shortly before their sixteenth birthday. Children with no Child Benefit claim behind them have to apply for a number themselves, which is an avoidable piece of administration years later.

Claim as soon as the birth is registered, or as soon as a child comes to live with you. You do not have to wait for the birth certificate to arrive if registration is delayed — claim and send the certificate afterwards.

You can claim online or through the HMRC app if you have a Government Gateway account, or on the paper CH2 form. The online route is faster and lets you upload the birth or adoption certificate. First claims need the original birth certificate or a certified copy, which HMRC returns.

You will need your own National Insurance number, your partner's if you have one, your bank details and the child's details. If you are claiming for an adopted, fostered or otherwise placed child, or a child born abroad, additional documents apply.

Backdating is short. A claim can only be backdated for a limited period, so a delay of months is money permanently lost. This is the practical reason to claim before the paperwork is perfect rather than after.

Payment is normally every four weeks into one account, though single parents and some people on other benefits can ask for weekly payment. It is paid to one person, not split.

If your income is high enough that the charge will claw back the whole payment, you can still claim and then choose not to receive the money. Do this through the claim itself rather than by not claiming — see the next section, because the difference between the two is years of National Insurance credits.

Tell HMRC promptly about changes: a child leaving education, a change of address or bank account, a child going into hospital or care for an extended period, a child going abroad, or a change in who the child lives with. Overpayments caused by late reporting are recoverable, and payments for a child who has left education are a very common source of them.

The charge applies where the adjusted net income of the highest earner in the household exceeds a threshold set by the Treasury. It is a tax charge on that individual, not a reduction in the benefit, and it is collected through Self Assessment.

Adjusted net income is not the same as salary. It is total taxable income from all sources — employment, self-employment, rental profit, savings interest above the allowances, dividends, taxable benefits in kind such as a company car — less certain deductions, principally pension contributions made in the right way and Gift Aid donations grossed up. Two people on the same salary can have very different adjusted net income.

That definition creates a genuine planning lever. Increasing pension contributions or making Gift Aid donations reduces adjusted net income and can reduce or remove the charge. Where income sits just above the threshold, the effective marginal rate on that slice of income — income tax, National Insurance and the clawback together — is very high, which makes a salary sacrifice pension contribution unusually efficient in that band. This is arithmetic rather than avoidance, but the amounts and thresholds change, so check the current figures before acting.

The charge is assessed on the higher earner regardless of who claims or who receives the money. A partner who has never received a penny of Child Benefit can be the person liable for the charge, and 'partner' includes a cohabiting partner as well as a spouse or civil partner. This catches people who move in together mid-year, and people who separate.

The person liable has to register for Self Assessment and file a return, even if they are taxed entirely through PAYE and have never filed before. Failing to do so has produced a long trail of penalty cases, because the liability arises from the partner's claim and people genuinely did not know they had it. HMRC has since moved to allow the charge to be collected through PAYE tax codes in some circumstances — check the current position rather than assuming Self Assessment is the only route.

Where household circumstances change mid-year — a separation, a new partner moving in, a job change — the charge is worked out on the relevant part of the year. Report changes rather than waiting for the return.

If the charge would claw back the entire payment, you can elect not to receive the payments while keeping the claim alive. This is the key mechanism and it is done through the Child Benefit claim, either at the outset or later.

Doing it this way preserves everything that matters other than the cash: the National Insurance credits for the claiming parent continue to accrue until the youngest child turns 12, the child still gets a National Insurance number automatically at 16, and the claim can be restarted at any point without a new application.

Not claiming at all achieves none of that. The distinction between 'claim but do not be paid' and 'do not claim' is the single most important detail on this page.

Restarting is straightforward and matters more than people expect, because incomes fall as well as rise. Redundancy, a career break, going part-time, a business having a bad year or a large pension contribution can all bring adjusted net income back below the threshold. Payments can be restarted, and where the charge turns out not to apply for a year in which you opted out, you may be able to claim the money for that period retrospectively within the time limits.

Where only part of the benefit would be clawed back — income above the threshold but below the point at which the charge equals the full benefit — taking the payment and paying the charge leaves you better off than opting out. Opting out is only sensible where the clawback would be total, and even then it is a choice about cash flow rather than about entitlement.

Keep the paperwork. Opting out, opting back in, and the dates each took effect are what HMRC will ask about if the return and their records disagree.

Child Benefit stops on 31 August on or after a child's sixteenth birthday unless they stay in approved education or training, and HMRC will write asking you to confirm. If you do not reply, payments stop automatically. This deadline generates a large volume of avoidable stopped payments every summer.

Approved education means full-time non-advanced study — A-levels, Scottish Highers, T-levels, NVQs up to level 3, home education started before 16 — at more than a set number of hours a week. University and other advanced courses do not count, and neither does a course paid for by an employer. Approved training schemes vary by nation, which is one of the places devolution shows up directly.

There is also an extension where a young person leaves education and registers for work or training with the careers service or armed forces, which continues the payment for a short further period. It has to be applied for.

Child Benefit is a reserved matter across the UK, so the rules are the same in Scotland, Wales and Northern Ireland — but the surrounding support is not. In Northern Ireland the benefit is administered separately through HMRC's Northern Ireland arrangements, and nidirect rather than GOV.UK is the reference point for the local process.

Scotland adds a separate payment on top. Scottish Child Payment, delivered by Social Security Scotland, is paid for eligible children in low-income households and is entirely distinct from Child Benefit, with its own application and its own rules. Receiving Child Benefit is part of how eligibility is established for some Scottish payments, which is another reason for low-income households in Scotland to make sure the Child Benefit claim exists.

Child Benefit also interacts with other support. It does not count as income for Universal Credit, but the child element of Universal Credit and the benefit cap are separate calculations that can be affected by household circumstances. Tax-Free Childcare and free childcare hours are separate schemes again, with their own applications and their own income tests, and claiming one does not trigger the others.
