The short answer
On a £100,000 salary in England, Wales or Northern Ireland for 2025/26 (standard allowance, no pension or student loan), you keep roughly £68,557 a year — about £5,713 a month (~£1,318/week). Income Tax is about £27,432; employee NI about £4,011. Combined Tax Bite ≈ £31,443.
At this level the personal allowance taper and/or additional rate dominate the conversation. Read the £100k cliff alongside this page if you’re negotiating a six-figure offer.
Full baseline breakdown
- Gross pay: £100,000
- Income Tax: £27,432
- National Insurance: £4,011
- Estimated net: £68,557 (£5,713 / month)
- You keep: ~69% · tax + NI: ~31%
Personal allowance taper — the £100k cliff
Between £100,000 and ~£125,140, you lose £1 of personal allowance for every £2 earned — an effective marginal rate that stings. At £100,000, you're right on the edge. Nudge the calculator to feel how fast the bite grows.
Scotland vs England/Wales/NI
Same £100,000 gross: Scotland keeps about £5,435/month vs £5,713 in England/Wales/NI — roughly £3,336/year less in Scotland in this model. Switch region in the calculator and watch the pie change. Full write-up: Scotland vs England tax.
What if you put 5% into a pension?
Modelled as coming off before tax and NI (common salary-sacrifice / net-pay style — your scheme may differ):
A 5% contribution costs about £242/month of take-home at £100,000, while ~£417 lands in the pot — the gap is tax + NI you didn’t pay. More detail: pension sacrifice guide.
Student loan (Plan 2 sketch)
Rough Plan 2 estimate (9% of income above ~£28,470): about £6,438/year (~£537/month). That would leave roughly £5,176/month after the baseline Tax Bite and Plan 2 — before other deductions. Plans 1/4/5 and postgraduate loans differ. See student loan impact.
