The 60% tax trap above £100,000
Once adjusted net income exceeds £100,000, your Personal Allowance is reduced by £1 for every £2 earned above that. Between £100,000 and £125,140 your effective marginal rate is 60% (40% income tax plus 40% on the lost allowance). Add 2% NI and it reaches 62%. A £1,000 bonus in this band leaves you with just £380.

Key things to know on £100,000
- →Mandatory Self Assessment: Income over £100,000 requires a Self Assessment tax return. Register with HMRC by 5 October after the end of the tax year. Failure to register can result in penalties.
- →Bonus timing: If a bonus would push you above £100,000, consider asking your employer to defer it to the next tax year, or increase pension contributions to offset it. A £1,000 bonus in the taper zone effectively nets only ~£380.
- →Annual pension allowance: You can contribute up to £60,000 a year to a pension (or 100% of earnings, whichever is lower) and receive tax relief. At 60% effective relief in the taper zone, pension contributions are the single best use of pension contributions here.
- →Gift Aid: Charitable donations via Gift Aid also reduce your adjusted net income, providing some taper relief. A £1,000 Gift Aid donation reduces adjusted net income by £1,250 (grossed-up), saving £500 at 40%.
- →Child Benefit: At £100,000 the HICBC fully claws back all Child Benefit (this happened at £80,000). Pension contributions bringing adjusted net income below £80,000 would restore it.
Frequently asked questions
What is the take-home pay on £100,000 in the UK?+
On a £100,000 salary in 2026/27 with no pension or student loan, you take home approximately £68,557 a year — around £5,713 a month or £1,318 a week. You pay £27,432 in income tax and £4,011 in National Insurance. Note: if your adjusted net income exceeds £100,000, your Personal Allowance begins to taper, so a salary of exactly £100,000 with no other income still attracts the full Personal Allowance.
What is the 60% tax trap at £100,000?+
Between £100,000 and £125,140, your Personal Allowance is reduced by £1 for every £2 of adjusted net income above £100,000. This creates an effective 60% marginal rate on that band: you pay 40% income tax on the income, plus you lose 50p of allowance per £1 earned — that lost allowance is also taxed at 40%, meaning 40% + 20% (tax on lost allowance) = 60%. NI at 2% adds to that. A pay rise from £100,000 to £101,000 costs you around £620 in extra tax.
How can I avoid the Personal Allowance taper?+
Pension contributions reduce your adjusted net income. If your adjusted net income (after pension contributions) stays at or below £100,000, you keep your full Personal Allowance of £12,570 and avoid the 60% trap entirely. A £10,000 salary sacrifice pension contribution on a £110,000 salary would bring adjusted net income to £100,000. Other options: Gift Aid donations also reduce adjusted net income for this purpose.
Is my Child Benefit affected at £100,000?+
Yes. The High Income Child Benefit Charge (HICBC) already fully tapers away Child Benefit once adjusted net income exceeds £80,000. At £100,000 you will owe the full HICBC unless you reduce your adjusted net income below £80,000 via pension contributions. At £100k+ it is typically not worth claiming Child Benefit unless you plan to use pension contributions to reduce your income significantly.
What is the effective tax rate at £100,000?+
On a £100,000 salary (with full Personal Allowance preserved), you pay £27,432 income tax and £4,011 NI — a total of £31,443. That is an effective overall rate of 31.4%. However, the marginal rate on any additional income between £100,000 and £125,140 is 62% (40% income tax + 2% NI + 20% on lost allowance). This is why pension planning is especially important at this salary level.
