Where £100,000 sits
£25,140 more and you reach additional rate (45%) starts.
By this point the Personal Allowance has gone entirely, so this figure is both the band start and the gross salary.
- ✓Income Tax starts at £12,570 — The first £12,570 is covered by the Personal Allowance.
- ✓Postgraduate Loan repayments start at £21,000 — 6% of everything above this, if you have this loan.
- ✓Plan 5 student loan repayments start at £25,000 — 9% of everything above this, if you have this loan.
- ✓Plan 1 student loan repayments start at £26,900 — 9% of everything above this, if you have this loan.
- ✓Plan 2 student loan repayments start at £29,385 — 9% of everything above this, if you have this loan.
- ✓Plan 4 student loan repayments start at £33,795 — 9% of everything above this, if you have this loan.
- ✓Higher rate (40%) starts at £50,270 — National Insurance drops from 8% to 2% at the same point, so the jump in your marginal rate is 20 points, not 26.
- ✓Personal Allowance starts being withdrawn at £100,000 — You lose £1 of allowance for every £2 above this, which is what makes the marginal rate here 62%.

How to check a £100,000 salary
This is the salary where the most misunderstood mechanism in UK tax switches on. Above this point the Personal Allowance is withdrawn as income rises, so each additional pound is taxed at the higher rate and simultaneously drags previously tax-free income into charge. The result is a marginal rate well above the band rate that appears on any rate table — and it applies to a stretch of income, then stops. Almost nobody notices, because no payslip ever names it. The calculator does: it shows the rate on your next pound alongside the headline figure, and works out how much a pension contribution would need to be to bring your income back below the threshold.
- 1Confirm the salary and read the marginal rate rather than the average rate.
- 2Note the warning about the withdrawal band, which appears once you are inside it.
- 3Add a pension contribution and watch the marginal rate fall as income returns below the threshold.
- 4Check the relief you would have to claim yourself if you are on relief at source.
FAQ
Why is the rate 62% and not 60%?
The 60% figure covers Income Tax only — the higher rate on the extra pound plus the tax on the allowance being withdrawn alongside it. National Insurance is still charged on top at the upper rate, which brings the total on that slice to 62%. The calculator shows the combined figure because that is what actually leaves your pay.
How much would I need to put into a pension to escape it?
Enough to bring the income the withdrawal is measured against back below the threshold. The calculator works out that amount from your own figures and shows it, rather than leaving you to solve it. Whether doing so is right for you is a question for an adviser, not for this page.
Does the trap apply to a bonus as well as salary?
It applies to income, so a bonus that carries you above the threshold has the same effect for the part above it. That is why people near this level sometimes ask for a bonus to be paid into a pension instead — the calculator shows the mechanical difference between the two outcomes.
