Register for child benefit even if the hicbc applies

Child benefit remains one of the most straightforward payments available from HMRC, yet many UK parents and carers are missing out simply because they’ve misunderstood the rules around the High Income Child Benefit Charge (HICBC). If your household earns above the threshold, you might assume it’s not worth registering—but you’d be making a costly mistake. Here’s why registering is always the sensible approach, even when the HICBC applies.

Understanding the High Income Child Benefit Charge

The HICBC was introduced in January 2013 and applies when any individual in a household has adjusted net income above £50,000 per tax year. For those earning between £50,000 and £60,000, the charge reduces the benefit by 1% for every £100 of income above the threshold. Anyone earning £60,000 or more loses the entire benefit to the charge.

It’s crucial to understand that the charge doesn’t prevent you from receiving child benefit—it simply means you’ll pay some or all of it back through Self Assessment. Many higher earners mistakenly skip registration altogether, assuming they won’t benefit. In reality, registering is actually essential if you fall into this bracket.

Why You Must Still Register

Registering for child benefit provides you with National Insurance credits, which are absolutely vital for your state pension entitlement. Even if the HICBC means you’ll repay every penny of the actual benefit, those National Insurance credits continue to accrue. Each week you’re entitled to child benefit counts as a qualifying week towards your state pension, and you cannot get these credits any other way if you’re not registered.

Consider this: you could be forgoing years of state pension qualification by not registering simply because you thought you wouldn’t “get” the money. The state pension is currently £221.20 per week (2024/25 tax year), so the long-term financial impact of missing those credits could be substantial.

Additionally, registering gives you an official record with HMRC that you’re a carer or responsible for children. This can be helpful for future benefits claims, tax credits verification, or other government support you might become eligible for.

How the Self Assessment Process Works

Once you’ve registered and received child benefit, you’ll need to declare the HICBC liability through your Self Assessment tax return. You’ll complete the relevant section, and HMRC will calculate exactly how much benefit you need to repay based on your adjusted net income for that tax year.

The repayment is straightforward: you simply owe the amount through your Self Assessment bill. Many accountants, including those of us at Severn Accounting, help clients navigate this annually to ensure accuracy and that they’re not overpaying or underpaying.

One practical tip: keep records of your child benefit awards throughout the year. This makes reconciling against your Self Assessment figures far easier when January rolls around and you’re preparing your tax return.

Timing and Future Changes

You should register for child benefit as soon as your child is born or as soon as they come into your care. Don’t delay because of income concerns. Registration is free, takes around 20 minutes online, and can be done through the GOV.UK website.

It’s also worth noting that the HICBC threshold hasn’t increased since 2013, despite general inflation and wage growth. This means more households drift into the charge each year. If your circumstances change—perhaps you’ve had a promotion or increased self-employment income—recalculate your position. Conversely, if your income drops below £50,000 in a given year, you might find you’re not subject to the charge at all that year, making the full benefit yours to keep.

The Bottom Line

Registering for child benefit is a no-brainer, regardless of your income. The worst-case scenario is that you repay some or all of the benefit through Self Assessment—but you’ll have gained valuable National Insurance credits and an official record of your circumstances. The best-case scenario is that your income drops below the threshold and you keep the full benefit.

Don’t let a misunderstanding of the HICBC cost you years of state pension entitlement. Register, then manage the tax position carefully each year.
