The 60% tax trap — what it is and why it matters
The trap illustrated
| Gross income | Personal Allowance remaining | Tax on next £10,000 | Effective marginal rate |
|---|---|---|---|
| £100,000 | £12,570 (full) | £4,000 | 40% |
| £102,000 | £11,570 | £6,000 | 60% |
| £110,000 | £7,570 | £6,000 | 60% |
| £120,000 | £2,570 | £6,000 | 60% |
| £125,140 | £0 (fully withdrawn) | £6,000 | 60% |
| £125,141+ | £0 | £4,500 | 45% (additional rate) |
Between £100,000 and £125,140, every £10,000 of extra income costs you £6,000 in tax. Earning £125,140 instead of £100,000 nets you only £15,084 more after tax on £25,140 extra gross income.
Why a bonus can make you worse off
If your base salary is £95,000 and you receive a £10,000 bonus, your adjusted net income becomes £105,000. The £5,000 above £100,000 is taxed at 60% effectively — you keep only £2,000 of that £5,000. The remaining £5,000 (below the threshold) is taxed at 40%, giving £3,000. Total from a £10,000 bonus: £5,000 net — 50% gone.
How to escape the 60% trap: pension salary sacrifice
The solution is straightforward: reduce your adjusted net income to £100,000 or below through pension contributions. Every pound contributed to a pension reduces adjusted net income pound for pound.
| Gross income | Pension contribution | Adjusted net income | PA preserved | Effective saving |
|---|---|---|---|---|
| £105,000 | £5,000 | £100,000 | Full (£12,570) | £3,000 saved |
| £110,000 | £10,000 | £100,000 | Full (£12,570) | £6,000 saved |
| £120,000 | £20,000 | £100,000 | Full (£12,570) | £12,000 saved |
| £125,140 | £25,140 | £100,000 | Full (£12,570) | £15,084 saved |
Contributing £10,000 to a pension when income is £110,000 costs just £4,000 net (40% relief on £10,000) but also restores £5,000 of Personal Allowance — giving an extra £2,000 saving. Net cost: £4,000. Total tax saved: £6,000.
Salary sacrifice vs personal contribution
| Method | Relief mechanism | NI saving? | Employer NI saving? |
|---|---|---|---|
| Salary sacrifice | Pre-tax deduction | Yes (small) | Yes |
| Personal contribution | 20% added by provider, reclaim 20% via SA | No | No |
Salary sacrifice is generally more efficient if your employer passes on their NI saving (13.8% of contribution).
Scotland comparison at £100,000
Scotland's income tax structure taxes £100,000 earners far more heavily. The 42% Higher Rate starts at £43,663 and the 45% Advanced Rate applies above £75,001. Additionally, Scotland has its own Personal Allowance taper — though the mechanics follow the UK-wide rules on adjusted net income.
| Band | Rate | Tax |
|---|---|---|
| Personal Allowance (£12,570) | 0% | £0 |
| Starter: £12,571–£15,397 (£2,827) | 19% | £537.13 |
| Basic: £15,398–£27,491 (£12,094) | 20% | £2,418.80 |
| Intermediate: £27,492–£43,662 (£16,171) | 21% | £3,395.91 |
| Higher: £43,663–£75,000 (£31,337) | 42% | £13,161.54 |
| Advanced: £75,001–£100,000 (£25,000) | 45% | £11,250.00 |
| Total Scottish IT | £30,763.38 |
| Component | England/Wales/NI | Scotland |
|---|---|---|
| Income tax | £27,432.00 | £30,763.38 |
| Employee NI | £4,010.60 | £4,010.60 |
| Net annual | £68,557.40 | £65,226.02 |
| Net monthly | £5,713.12 | £5,435.50 |
| Difference | -£3,331.38/yr |
Scottish taxpayers at £100,000 pay approximately £3,331 more per year than in England. The Personal Allowance taper applies in Scotland too — Scottish residents earning above £100,000 face the same 60% effective marginal rate mechanism.
HICBC at £100,000
At £100,000, the HICBC has been fully payable for some time. All Child Benefit is clawed back (HICBC is 100%). However, this is also the threshold where pension contributions become most financially rewarding:
| Scenario | Child Benefit/yr | HICBC (100%) | Pension contribution to £60k | CB restored | Total benefit of contribution |
|---|---|---|---|---|---|
| 1 child | £1,331 | £1,331 | £40,000 | £1,331 | £16,000 tax + £1,331 CB |
| 2 children | £2,212 | £2,212 | £40,000 | £2,212 | £16,000 tax + £2,212 CB |
Note: for most households at £100,000, the priority is first reducing income to £100,000 (to escape the PA taper), then to £60,000 (to restore Child Benefit) if applicable.
Pension strategy: the numbers at £100,000
At exactly £100,000 (before any contributions), your higher-rate exposure is £49,730 and you are right at the PA taper threshold.
| Annual pension contribution | Tax saved | Net cost | Into pension | Adjusted net income |
|---|---|---|---|---|
| £5,000 | £2,000 | £3,000 | £5,000 | £95,000 |
| £10,000 | £4,000 | £6,000 | £10,000 | £90,000 |
| £30,000 | £12,000 | £18,000 | £30,000 | £70,000 |
| £49,730 (eliminate HR band) | £19,892 | £29,838 | £49,730 | £50,270 |
At exactly £100,000 with no contributions, you retain the full Personal Allowance. The trap bites if income rises above this — see the sections above for the bonus scenario.
Student loan repayments
| Plan | Threshold | Earnings above threshold | Rate | Annual | Monthly |
|---|---|---|---|---|---|
| Plan 1 | £24,990 | £75,010 | 9% | £6,751 | £562.58 |
| Plan 2 | £27,295 | £72,705 | 9% | £6,543 | £545.25 |
| Plan 5 | £25,000 | £75,000 | 9% | £6,750 | £562.50 |
| Postgraduate Loan | £21,000 | £79,000 | 6% | £4,740 | £395.00 |
With a Plan 2 loan, net take-home falls to approximately £56,214/yr (£4,685/month).
What does £5,713/month get you?
At £5,713.12 per month net, a £100k earner in 2026 has strong spending power — but the HICBC, student loans, and the proximity to the PA taper can erode this quickly without planning.
| Expense | Monthly estimate |
|---|---|
| Mortgage/rent | £1,600–£2,500 |
| Council tax | £160–£260 |
| Utilities + broadband | £200–£280 |
| Groceries (family of 2–3) | £450–£600 |
| Transport | £250–£450 |
| Childcare (1 child) | £800–£1,400 |
| Pension contribution | £800–£2,000 |
| Discretionary/savings | Remainder |
The single most impactful financial decision for most £100,000 earners is pension salary sacrifice. Avoiding the 60% marginal rate and HICBC simultaneously, while building long-term wealth, makes this a near-universal recommendation.

Frequently asked questions
What is £100,000 after tax in the UK for 2026/27?
£100,000 gross leaves £68,557.40 net per year — about £5,713 per month — after income tax (£27,432) and National Insurance (£4,010.60) in England for 2026/27.
What is the 60% tax trap at £100,000?
Above £100,000, you lose £1 of Personal Allowance for every £2 of extra income. This means each extra £2 earned is taxed at 40%, but you also lose £1 of 0% allowance which gets taxed at 40% too — effectively 60% on every pound between £100,000 and £125,140. NI is not relevant here as it sits above the Upper Earnings Limit.
How can I avoid the 60% tax trap at £100,000?
Pension salary sacrifice or personal pension contributions reduce your adjusted net income. Contributing enough to bring adjusted net income to £100,000 or below preserves the full £12,570 Personal Allowance and avoids the 60% marginal rate entirely.
How much income tax do I pay on £100,000?
£27,432 income tax: £7,540 at 20% on the first £37,700 above the Personal Allowance, plus £19,892 at 40% on the £49,730 between £50,270 and £100,000. The full Personal Allowance of £12,570 is still retained at exactly £100,000.
What is £100,000 after tax in Scotland for 2026/27?
Scottish taxpayers at £100,000 pay significantly more income tax, with the 45% Advanced Rate applying above £75,001. Scottish net pay is around £6,000–£7,000 per year less than in England at this salary level.
