The High Income Child Benefit Charge at £85,000
The HICBC reached 100% clawback at £80,000. At £85,000, your Child Benefit is entirely repaid via Self Assessment regardless of how many children you have. You receive nothing from Child Benefit in net terms.
What You Are Losing
| Children | Annual Child Benefit | Amount clawed back (100%) | Net benefit |
|---|---|---|---|
| 1 child | ~£1,354 | −£1,354 | £0 |
| 2 children | ~£2,254 | −£2,254 | £0 |
| 3 children | ~£3,094 | −£3,094 | £0 |
Many families in this position simply stop claiming Child Benefit to avoid the Self Assessment administration. However, claiming and repaying still protects the primary carer’s State Pension NI record — it is worth claiming for this reason alone even if the net cash benefit is zero.
Recovering Child Benefit with a Pension
To begin recovering Child Benefit, your adjusted net income needs to fall below £80,000.
| Target adjusted net income | Required pension contribution | Child Benefit recovered (2 children) | IT/NI saved | Net cost of contribution |
|---|---|---|---|---|
| £80,000 (HICBC still 100%) | £5,000 | £0 | £2,100 | £2,900 |
| £75,000 (75% clawback) | £10,000 | £564 | £4,200 | £5,236 |
| £65,000 (25% clawback) | £20,000 | £1,691 | £8,400 | £9,909 |
| £60,000 (0% clawback) | £25,000 | £2,254 | £10,500 | £12,246 |
A £25,000 contribution to eliminate the HICBC entirely saves £10,500 in tax/NI and recovers £2,254 in Child Benefit — total benefit £12,754. Net cost in take-home: £12,246. The £25,000 goes into your pension, so your total wealth position improves.

The £100,000 Trap: You Are £15,000 Away
This is the single most important planning point at £85,000. Once adjusted net income exceeds £100,000, the Personal Allowance tapers at £1 per £2 above £100,000. The effective marginal rate jumps to 60%.
| Adjusted net income | Allowance lost | Extra tax on that income | Effective marginal rate |
|---|---|---|---|
| £100,000–£100,999 | £0–£499 | 40% on the income | 40% |
| £101,000 | £500 | £200 extra | 60% |
| £110,000 | £5,000 | £2,000 extra | 60% |
| £125,140 | £12,570 (all gone) | £5,028 extra | 60% |
On an £85,000 base salary, you can receive up to £14,999 in additional income (bonus, rental, interest, dividends) before hitting this trap. Anything beyond that is taxed at 60%.
Salary Sacrifice to Protect Against the Trap
If a bonus or pay rise risks taking your total above £100,000, salary sacrificing the amount above £85,000 into a pension keeps adjusted net income below the taper threshold and saves 42p per pound instead of losing 60p.
Example: £85,000 salary + £20,000 bonus = £105,000 total
Without salary sacrifice: the £15,001–£20,000 portion (£4,999) is taxed at 60% effective rate = extra £2,000 tax versus a standard 42% rate.
With a £20,000 pension sacrifice: adjusted net income = £85,000, 60% rate avoided, total pension benefit = £8,400 tax/NI saving.
See our £100,000 salary tax guide.
Pension Contributions at £85,000
All contributions fall entirely in the higher rate band (40% IT + 2% NI):
| Gross pension contribution | IT saved | NI saved | Total saved | Net cost |
|---|---|---|---|---|
| £5,000 | £2,000 | £100 | £2,100 | £2,900 |
| £10,000 | £4,000 | £200 | £4,200 | £5,800 |
| £15,000 (buffer below £100k) | £6,000 | £300 | £6,300 | £8,700 |
| £25,000 (to HICBC threshold) | £10,000 | £500 | £10,500 | £14,500 |
| £34,730 (to basic rate) | £13,892 | £695 | £14,587 | £20,143 |
See our Pension Tax Relief Guide and Salary Sacrifice Guide.
What If You Earn a Bonus?
A bonus on £85,000 is taxed at 42% until income reaches £100,000 — at which point the 60% effective rate kicks in. Plan all bonuses with this threshold in mind.
Example: £85,000 + £10,000 bonus = £95,000
The full bonus falls in the higher rate band: £4,000 Income Tax + £200 NI = £4,200 deducted. You keep £5,800 of the £10,000 bonus.
Example: £85,000 + £20,000 bonus = £105,000
£15,000 at 42% = £6,300 in tax/NI, then £5,000 triggers PA taper: additional £2,000 extra tax. Total deductions: £8,300. You keep £11,700 of the £20,000 bonus — but at a blended rate well above 40%.
