The £100k Tax Trap: 60% Effective Marginal Rate
At exactly £100,000, your Personal Allowance is still intact. But earning even £1 over £100,000 triggers the Personal Allowance taper:
- • For every £2 earned over £100,000, you lose £1 of your £12,570 Personal Allowance
- • This creates an effective 60% marginal tax rate on income between £100,001 and £125,140
- • At £125,140, your Personal Allowance is completely gone
- • A £5,000 pay rise to £105,000 would only increase take-home by roughly £1,900 — not £2,900 as you might expect
Why 60%?
40% income tax + 20% effective tax from losing £1 PA for every £2 earned = 60% marginal rate. Add 2% NI and it's actually 62%.
How to Avoid the Trap
Make pension contributions or use salary sacrifice to keep your adjusted net income at or below £100,000. This preserves your full Personal Allowance and avoids the 60% marginal rate. Read our full guide to the £100k tax trap.
If you're earning £100,000 a year in the UK, you're in the top 2% of earners. At exactly £100,000, you still have your full Personal Allowance — but this is the last salary level where that's the case. Understanding the tax trap above this threshold is essential.
After income tax and National Insurance, you'll take home approximately £68,557 per year, or £5,713 per month. That means you're keeping about 68.6% of your gross salary, with an effective tax rate of 31.4%.

How Your Tax is Calculated
Step 1: Personal Allowance
The first £12,570 of your income is tax-free. At exactly £100,000, your Personal Allowance is still intact — but earning any more will start to reduce it.
Step 2: Basic Rate Income Tax (20%)
Income from £12,571 to £50,270 is taxed at 20%.
£50,270 - £12,570 = £37,700
£37,700 × 20% = £7,540 basic rate tax
Step 3: Higher Rate Income Tax (40%)
Income above £50,270 is taxed at 40%.
£100,000 - £50,270 = £49,730
£49,730 × 40% = £19,892 higher rate tax
Step 4: National Insurance
NI is 8% on earnings between £12,570 and £50,270, then 2% above that.
£37,700 × 8% = £3,016
£49,730 × 2% = £995
Total NI: £4,011

Tips to Maximise Your Take-Home Pay
Pension contributions = 40% tax relief (or 60% above £100k)
As a higher rate taxpayer, you get 40% tax relief on pension contributions. If your income goes above £100k, pension contributions that bring you back below the threshold effectively get 60% relief because they restore your Personal Allowance.
Salary sacrifice to stay at or below £100k
If bonuses or pay rises push you above £100k, salary sacrifice into pension is the most tax-efficient strategy available. It reduces your adjusted net income, preserves your Personal Allowance, and saves NI too.
Charitable giving via Gift Aid
Gift Aid donations reduce your adjusted net income. As a 40% taxpayer, you can claim back the difference between the higher rate (40%) and basic rate (20%) through Self Assessment. Donations can also help you stay below the £100k taper threshold.
