What's the take-home on £100,000 in 2026/27?

The full breakdown for England, Wales and Northern Ireland

Tax and NI take 31.4% and about 69p of each pound is kept, with the full £12,570 allowance still intact — the highest salary on this ladder where that is true.

The Scottish version is different

£25,000 of this salary is taxed at Scotland's 45% advanced rate, costing £1,250 more than the rest of the UK's 40%; the other £2,050 of the gap is the same one a £75,000 earner faces.

Why £100,000 is the start of the worst tax band in the UK system

The personal allowance tapers between £100,000 and £125,140. For every £2 you earn above £100,000, your personal allowance reduces by £1. At £125,140 the personal allowance is gone entirely.

The arithmetic is brutal. A £1 pay rise above £100,000 gets you:

• Lose £0.40 to higher-rate income tax (40% on the new £1)
• Lose another £0.20 to lost personal allowance — because £0.50 of personal allowance goes, and that £0.50 was previously sheltered from 40% tax, so you now pay 40% × £0.50 = £0.20 extra
• Plus £0.02 NI on the new £1
• Total marginal deduction: 62%. You keep £0.38 of every gross pound earned in this band.

For five-figure pay rises, lump sums or bonuses, this band is genuinely brutal. A £25,000 bonus paid into the £100,000–£125,000 zone takes home about £9,500 — the rest goes to HMRC.

The defensive playbook is well-established and works:

1. Sacrifice into a pension until your taxable salary lands at exactly £100,000. The slice you sacrifice gets effectively 62% relief — the highest rate available anywhere in England, Wales or Northern Ireland. (A Scottish taxpayer in the same band does better still, at 69.5%.)
2. Use Gift Aid on charitable donations — this extends your basic-rate band, with the same effect as a pension contribution.
3. If you have a partner with unused allowances or basic-rate band capacity, splitting investment income via a joint account or transfer of dividend-bearing shares can shift income out of your 60% band.

The 60% tax trap guide walks through the full mechanics. The adjusted net income calculator shows how much you would need to sacrifice to escape the band cleanly.

Who actually earns £100,000 in the UK?

Almost nobody, as a job rather than as a career peak. Of the 412 four-digit occupations in ASHE Table 14, exactly one has a median full-time salary at this level: chief executives and senior officials, at £99,944 across 112,000 full-time jobs.

The gap to second place is £5,809 — marketing, sales and advertising directors at £94,135, an occupation employing nearly twice as many people (200,000 full-time jobs). Behind them come specialist medical practitioners (£92,847, 142,000 jobs), IT directors (£91,671, 56,000 jobs), directors in logistics, warehousing and transport (£83,447), and aircraft pilots and air traffic controllers (£82,746). Nothing else in the table comes within £5,000 of £100,000.

The distribution tells the same story. The ONS ad-hoc release J76, drawn from the same survey, puts the full-time 95th percentile at £99,387 and the 96th at £107,496, so £100,000 is a top-5% salary nationally. Measured against all employee jobs including part-time, the 96th percentile is £97,616.

Geography then rewrites it entirely. In London the full-time 90th percentile alone is £115,775 — £100,000 does not reach the capital's top decile. In England excluding London the 95th percentile is £87,531 and the 97th is £101,249, so the identical salary is a top-3% income outside London. All figures are ASHE 2025 provisional, published 23 October 2025.

Does £100,000 trigger the tapered annual allowance?

No — and the confusion is expensive, because it talks people out of the one contribution that works hardest at exactly this salary.

The tapered annual allowance is a different rule at a different income. It applies only if your threshold income exceeds £200,000 and your adjusted income exceeds £260,000. It then cuts the allowance by £1 for every £2 of adjusted income above £260,000, and it cannot fall below £10,000 — the mechanics are set out in HMRC's Pensions Tax Manual at PTM057100. A £100,000 salary fails both tests, so the full £60,000 annual allowance stands, with up to three years of unused allowance available on top through carry-forward.

What does bite at £100,000 is the personal allowance taper — a separate mechanism, in a separate part of the tax system, that happens to start at the same round number. At exactly £100,000 it has not started yet: the full £12,570 allowance is intact, income tax is £27,432, National Insurance is £4,010.60 and take-home is £68,557.40, an effective deduction rate of 31.4%. It is the pound after that one which is taxed at 62%.

The second myth worth killing: your personal savings allowance is still £500 here, not nil. It only falls to zero when you become an additional-rate taxpayer at £125,140, so at this salary you can still take £500 of interest tax-free outside an ISA.

What happens to free childcare above £100,000?

It vanishes — all of it, at once. Free childcare for working parents — 30 hours a week for 38 weeks of the year for children aged nine months to four, which is 1,140 funded hours per child per year — and Tax-Free Childcare, worth £500 a quarter or £2,000 a year per child (£1,000 a quarter, £4,000 a year for a disabled child), are both withdrawn outright if either parent's adjusted net income exceeds £100,000 for the tax year.

This is a cliff, not a taper. One pound of extra income removes the entire entitlement, for both parents, for every child. It is the largest single discontinuity in the UK system for a working family, and it exists at no other rung on this ladder. Three- and four-year-olds keep the universal 15 hours whatever you earn, so the damage is heaviest for under-threes, who lose all 30. The Department for Education's 2026 to 2027 early years funding rates average £6.63 an hour for the universal three- and four-year-old entitlement and £6.56 for the additional working-parent hours, which is the public price tag on the hours at stake. The minimum-earnings side of the same test is £2,643.68 over three months for a parent aged 21 or over.

Hence the planning decision that belongs only to this salary: hold adjusted net income at exactly £100,000 using pension contributions, salary sacrifice or Gift Aid. The first pound over the line costs 62p in tax and can cost thousands in childcare.

One more number that only makes sense here: the statutory auto-enrolment minimum at £100,000 is just £3,522.40, because qualifying earnings are capped at £50,270. That is 3.5% of your actual pay, of which your employer's legal minimum is £1,320.90 — 1.3%. Defaults designed for a £30,000 salary do not do the job at this one.

What this calculation does not include

• Pension contributions. A 5% employee contribution on full pay is £5,000 here, and every pound of it attracts 40% relief because your top slice sits in the higher-rate band — £5,000 in the pot for a £3,000 net cost. Take it by salary sacrifice and the NI saving is only 2%, not the 8% someone at £40,000 gets, because £100,000 is far above the £50,270 upper earnings limit. What the contribution really buys at this salary is a lower adjusted net income. Model it in the salary sacrifice calculator.
• Student loan repayments. At £100,000 you clear every repayment threshold by a wide margin, so your plan changes the amount but not the fact: 9% of everything above the threshold on Plan 1, Plan 2, Plan 4 and Plan 5, plus 6% more for a Postgraduate Loan. That turns the 42% marginal rate on your top slice into 51%, or 57% with both — a graduate keeps 43p of the last pound instead of 58p. Repayments are not deducted from adjusted net income either, so they do nothing to keep you under the £100,000 line.
• Bonuses, overtime and one-off payments. From exactly £100,000 a bonus is the worst-taxed money in the UK system: its first £25,140 lands wholly inside the 62% band, so £10,000 gross reaches your account as £3,800. Cumulative PAYE may over-deduct in the month it is paid and unwind later, but the permanent damage is different — a bonus that lifts adjusted net income over £100,000 forfeits the childcare entitlements above for the whole tax year.
• Benefits in kind. A P11D benefit carries no employee National Insurance, so the marginal cost here is 60% rather than 62% — a £1,200 private medical policy costs £720 once it pushes your income past £100,000, because £600 of personal allowance dies with it. The bigger risk is that benefits count toward adjusted net income and can cross the childcare line on their own, with no pay rise involved. An electric company car taken by salary sacrifice is one of the few that moves you the other way.
• Multiple jobs. A second employer on a BR code deducts 20% when your real marginal rate is 62%, leaving a Self Assessment bill of up to 42p in the pound on that income — a D0 code is usually the right ask. National Insurance is charged separately by each employment, so a second job restarts the 8% band that your main salary exhausted long ago at 2%.
