The High Income Child Benefit Charge: 5 Worked Examples for 2026/27

Quick answer

The High Income Child Benefit Charge (HICBC) is one of the most complex and poorly understood aspects of the UK tax system. Introduced in 2013 and significantly reformed in 2024, it claws back Child Benefit from households where the highest earner has an adjusted net income above £60,000. The charge reaches 100% at £80,000 — meaning the benefit is entirely wiped out.

The 2024 reform was significant: the taper was widened from £50,000–£60,000 to £60,000–£80,000, reducing the marginal tax rate in the danger zone and giving relief to those earning between £50,000 and £60,000 who previously lost all their Child Benefit.

This guide gives you five worked examples covering the key scenarios in 2026/27.

Child Benefit rates for 2026/27

Before the worked examples, you need to know the benefit amounts at stake.

So for a family with 2 children, total Child Benefit is £1,354.60 + £897.00 = £2,251.60/year.

For a family with 3 children, it is £1,354.60 + £897.00 + £897.00 = £3,148.60/year.

How HICBC is calculated

The charge is expressed as a formula:

HICBC = (Adjusted Net Income − £60,000) ÷ 200 × 1% of total Child Benefit received

Or more simply: for every £200 of income above £60,000, you repay 1% of the benefit. At £80,000, you have passed £20,000 above the threshold — 100 × 1% = 100% repaid.

Adjusted net income is your total income minus:

• Pension contributions (both personal and employer salary sacrifice)
• Gift Aid donations (grossed up)
• Trading losses

It is not reduced by things like travel-to-work costs, professional subscriptions, or other employment expenses.

Worked example 1: Single earner £65,000, two children — partial HICBC

Scenario: Sarah is a marketing director earning £65,000/year. She has two children and claims Child Benefit.

Sarah keeps 75% of her Child Benefit. She must register for Self Assessment if she is not already registered, and declare the HICBC on her tax return.

Should she opt out of receiving payments? Probably not — she keeps £1,688.70/year of net benefit. The hassle of Self Assessment is worth tolerating for that sum. However, she could reduce the charge or eliminate it entirely by making pension contributions.

If Sarah makes a £5,100 personal pension contribution, her adjusted net income drops to £59,900 (below £60,000), and the HICBC disappears entirely. She also gets 40% tax relief on the contribution, making the pension contribution itself highly tax-efficient.

Worked example 2: £75,000 earner, three children — HICBC vs opting out

Scenario: David earns £75,000 as a project manager. He has three children.

David is in a tricky position. He still keeps £787.15/year in net benefit, but he must file a Self Assessment return to pay the charge. The question is whether the admin burden is worth £787.15.

Decision tree:

• Income expected to rise above £80,000 soon? → Consider opting out of payments now, keep NI credits claim active.
• Income likely to fall below £75,000 next year? → Keep claiming — you will owe less.
• Can you make pension contributions? → A £15,100 additional pension contribution drops adjusted net income to £59,900, eliminates all HICBC, saves £2,361 in charge, and attracts 40% tax relief worth £6,040 on the contribution. Total annual benefit of this strategy: over £8,000.

Worked example 3: Couple each earning £55,000 — neither pays HICBC

Scenario: Emma and Jack both earn £55,000. They have two children. Emma claims Child Benefit.

This example illustrates the well-known anomaly of the HICBC system: Emma and Jack keep all £2,251.60 of Child Benefit, despite a combined household income of £110,000.

Compare this to a single-earner household where one partner earns £75,000: that household, despite lower combined income, loses 75% of its Child Benefit. The individual-income basis of HICBC creates a significant penalty for single-earner families that two-income families avoid entirely.

This anomaly has been criticised by the Office of Tax Simplification and various parliamentary committees, but as of 2026 it remains unchanged. The government has not announced plans to move to a household income basis.

Worked example 4: £78,000 earner uses pension salary sacrifice to save over £900

Scenario: Priya earns £78,000. She has two children. She is considering increasing her pension salary sacrifice.

Current position (no sacrifice beyond auto-enrolment):

Priya is paying £2,026 to keep £225 — a highly inefficient outcome.

Strategy: salary sacrifice £18,100/year extra into pension:

Total annual financial benefit of salary sacrifice strategy: approximately £4,415 (NI saving + HICBC elimination + Child Benefit retention). Plus Priya is building up a significantly larger pension pot with 40% effective tax relief on contributions.

The key practical point: salary sacrifice must be agreed with the employer and documented in an amended employment contract. It cannot be done retrospectively.

Worked example 5: £82,000 earner — claim benefit for NI credits only

Scenario: Mark earns £82,000. He has two children. Should he bother claiming Child Benefit at all?

Mark's adjusted net income exceeds £80,000, so he repays 100% of Child Benefit via HICBC. The financial case for claiming the benefit payment is zero — he receives nothing.

But should he still claim?

Yes — absolutely. Claiming Child Benefit with the payment opted out is the correct strategy. Here is why:

1. National Insurance credits: The claiming parent (or the non-working partner) accumulates Class 3 NI credits for each child under 12. Each year of credits counts toward the 35 qualifying years needed for a full New State Pension (currently worth £11,973/year). Losing even one year of NI credits has a cost of approximately £342/year in State Pension from age 66 for the rest of your life.

2. Child's NI number: The Child Benefit claim ensures the child is registered with HMRC and receives their National Insurance number automatically at age 16. Not claiming can create administrative complications later.

3. You can opt out of receiving payments: Via gov.uk/child-benefit, you can claim Child Benefit and simultaneously opt out of receiving the payments. This gives you the NI credits and the NI number registration without receiving payments and without owing any HICBC.

Mark should claim Child Benefit, opt out of receiving payments, and file no HICBC on Self Assessment (since he receives no payments, there is no charge to declare).

The decision framework: should I claim Child Benefit?

Use this decision tree:

Do you have children under 16?
└── YES → Claim Child Benefit (always register)
    └── Is your adjusted net income (or your partner's if higher) below £60,000?
        ├── YES → Receive full payment, no HICBC. Done.
        └── NO → Is it above £80,000?
            ├── YES → Opt out of payments, keep NI credits. File no HICBC.
            └── NO (£60k–£80k) → Can you reduce income below £60k via pension/salary sacrifice?
                ├── YES → Do so. Eliminate HICBC entirely. Receive full payment.
                └── NO → Claim payment, calculate HICBC, file Self Assessment.
                          Is the net benefit (after HICBC) worth the admin burden?
                          Probably yes if you have multiple children.

Self Assessment requirement

You must register for and file a Self Assessment return if the HICBC applies to you — even if you are an employee whose tax is normally collected through PAYE. The deadline for online Self Assessment is 31 January following the end of the tax year (so for 2026/27, deadline is 31 January 2028).

If you are only filing because of HICBC, the process is straightforward: you report the Child Benefit received and HMRC calculates the charge. But missing the deadline triggers a £100 automatic penalty, so set a reminder.

What has changed since the original rules?

The original HICBC taper ran from £50,000 to £60,000, meaning the effective marginal tax rate in that band was extremely high — some calculations put it above 60% for families with several children. From April 2024, the government widened the taper to £60,000–£80,000:

This means anyone earning between £50,000 and £60,000 no longer pays HICBC at all — a significant tax reduction for around 170,000 families.

Frequently asked questions

Can HICBC be avoided by transferring the Child Benefit claim to the lower-earning partner?

HMRC scrutinises this. If the Child Benefit is received by Partner A (low earner), but Partner B (high earner) is the one assessed for HICBC (as the higher earner in the household), the charge is still based on Partner B's income. Moving the claim to the lower earner does not change who pays HICBC.

Is HICBC charged if I receive Child Benefit for a foster child?

HICBC applies to Child Benefit received for children you are responsible for. Foster children placed by a local authority are generally not included in Child Benefit claims, so this situation usually does not arise.

What if I repay too much or too little via Self Assessment?

HMRC reconciles in-year Child Benefit payments against the HICBC charge when you file your return. If you have overpaid (e.g., you stopped receiving benefit partway through the year), you will be credited. If you underpaid, interest accrues from 31 January.

Does Child Benefit count as taxable income?

No — Child Benefit itself is not taxable income. The HICBC is a separate tax charge that partially or fully offsets it.

My income varies year to year around the £60,000 threshold — what should I do?

If your income fluctuates around the threshold, keep claiming Child Benefit payments. In years when your income is below £60,000, you receive the full benefit. In years when it is above, you pay the charge via Self Assessment. Opting out permanently because of one high-income year, then having income fall again, means you miss out on payments you were entitled to.
