Navigating the High Income Child Benefit Charge (HICBC) requires careful attention to a taxpayer’s Adjusted Net Income (ANI), particularly for those with variable earnings. For partners in a firm or Limited Liability Partnership (LLP), calculating this income presents unique challenges due to the fiscal transparency of partnerships.
The Finance Act 2024 significantly reformed the HICBC thresholds. This article explores how these rules apply in the 2026/27 tax year, focusing on how partnership income interacts with the HICBC framework through a practical case study.
The 2026/27 HICBC Mechanics
Section 681B of the Income Tax (Earnings and Pensions) Act 2003 (ITEPA 2003) establishes the foundation of the HICBC. A taxpayer faces a charge if their Adjusted Net Income (ANI) exceeds £60,000 and either they or their partner claims Child Benefit.
Where both partners have an ANI exceeding the threshold, the legislation places the charge solely on the partner with the highest ANI.
The government increased the starting threshold to £60,000 from 6 April 2024, meaning this higher limit fully applies to the 2026/27 tax year. The rate at which the HICBC withdraws the Child Benefit also halved.
The Taper and Full Clawback
Section 681C of ITEPA 2003 calculates the exact charge using a specific formula. For the 2026/27 tax year, the charge equates to 1% of the total Child Benefit award for every £200 of income that exceeds the £60,000 threshold.
| Income Level | HICBC Effect (2026/27) |
|---|---|
| Below £60,000 | No HICBC liability. Taxpayer keeps all Child Benefit. |
| £60,000 to £80,000 | Sliding scale taper. 1% charge for every £200 over £60,000. |
| £80,000 and above | 100% of the Child Benefit is clawed back through the tax charge. |
Taxpayers retain two choices: they can receive the payments and pay the tax charge through Self Assessment, or they can “opt out” of receiving the payments to avoid the charge entirely while protecting their National Insurance credits.
Partnerships and Adjusted Net Income (ANI)
To determine HICBC liability, one must calculate the taxpayer’s Adjusted Net Income under section 58 of the Income Tax Act 2007. For partners, this requires an understanding of UK partnership taxation.
Partnerships and LLPs are fiscally transparent for income tax purposes. Section 848 of the Income Tax (Trading and Other Income) Act 2005 (ITTOIA 2005) confirms that a firm is not regarded as a separate and distinct entity from its partners.
Furthermore, section 863 of ITTOIA 2005 applies this specifically to LLPs carrying on a trade.
For income tax purposes, if a limited liability partnership carries on a trade, profession or business with a view to profit – (a) all the activities of the limited liability partnership are treated as carried on in partnership by its members (and not by the limited liability partnership as such)…
Consequently, a partner’s ANI includes their allocated share of the partnership’s trading profits, regardless of whether the partnership distributed those profits in cash.
The High Income Child Benefit Charge: A Partnership Case Study
To illustrate how these rules operate, consider the following scenario for the 2026/27 tax year.
Background: Sarah is a partner in an architectural LLP. Her husband, David, claims Child Benefit for their two children, amounting to £2,212.60 for the year. David earns a fixed salary of £45,000. Sarah’s income consists entirely of her profit allocation from the LLP.
The Partnership Allocation
For the 2026/27 tax year, the LLP achieves strong financial results. The partnership statement allocates a taxable trading profit of £71,000 to Sarah. The LLP retains £15,000 of her share as working capital, distributing only £56,000 to her personal bank account.
Step 1: Determining the Liable Partner
Sarah and David meet the definition of partners under section 681G of ITEPA 2003. Because Sarah’s Adjusted Net Income exceeds David’s, she is the partner liable for the HICBC, even though David receives the Child Benefit payments.
Step 2: Calculating Adjusted Net Income (ANI)
Because the LLP is fiscally transparent, Sarah pays tax on her full allocated profit share, not her cash drawings. Therefore, her ANI for HICBC purposes is £71,000, which sits within the £60,000 to £80,000 taper band.
Step 3: Calculating the HICBC Liability
We must determine how far Sarah’s ANI exceeds the £60,000 threshold.
- Excess Income = £71,000 – £60,000 = £11,000.
The charge is 1% for every £200 of excess income.
- Multiplier = £11,000 / £200 = 55.
Sarah must pay a tax charge equal to 55% of the total Child Benefit received.
- HICBC Liability = 55% of £2,212.60 = £1,216.93.
Sarah must declare and pay this £1,216.93 charge through her 2026/27 Self Assessment tax return.
Compliance and the “Failure to Notify” Trap
Partners often experience fluctuating incomes due to variable business profits. A partner earning £55,000 one year may unexpectedly receive a profit allocation of £65,000 the next year, pushing them into the HICBC regime.
Taxpayers possess a statutory obligation to notify HMRC of their chargeability to tax. If a partner fails to notify HMRC that their ANI has breached the £60,000 threshold, HMRC can issue discovery assessments to claw back the charge, often accompanied by penalties. Tribunals have consistently held that ignorance of the HICBC threshold is rarely a reasonable excuse for failing to notify chargeability, given the extensive awareness campaigns run by HMRC.
Consider exploring how claiming specific tax reliefs, such as making personal pension contributions or Gift Aid donations, can actively reduce a partner’s Adjusted Net Income for HICBC purposes.
