The UK uses a progressive tax system — you pay different rates on different portions of your income, not a flat rate on everything you earn.

The 60% tax trap: Between £100,000 and £125,140 your personal allowance is withdrawn at £1 for every £2 earned, so you are taxed on income that would otherwise be tax-free. While the allowance is being lost at the higher rate this makes the marginal Income Tax rate 60%. That is not the whole deduction: employee National Insurance adds 2 percentage points. UKCalc calculates the combined Income Tax and employee National Insurance marginal deduction rate as 62% from £100,000 to £125,140. That combined figure is a UKCalc calculation, not a published HMRC tax band. Pension contributions reduce the income the taper is measured against.

Frequently Asked Questions
On a £30,000 salary in 2026/27, you pay £3,486 in income tax and approximately £1,394 in National Insurance, leaving a monthly take-home of around £2,093. That is an effective Income Tax rate of 11.6%, or 16.3% once employee National Insurance is included.
The personal allowance for 2026/27 is £12,570. You pay no income tax on earnings below this threshold. It is tapered away for earnings over £100,000.
Between £100,000 and £125,140 your personal allowance is withdrawn at £1 for every £2 earned while income is still in the higher-rate band, which makes the marginal Income Tax rate 60%. The taper runs the whole way to £125,140. Employee National Insurance is charged on top, so the combined marginal deduction rate UKCalc calculates is 62% across the whole £100,000–£125,140 range — UKCalc calculations combining Income Tax and employee National Insurance, not official HMRC bands. Pension contributions can bring your income below £100,000 and restore the allowance in full.
Yes. Contributions made via salary sacrifice reduce your taxable income before tax and NI are applied, saving you both income tax and National Insurance. For a higher-rate taxpayer, every £100 contributed to a pension only costs £60 net.
Employees pay 8% NI on earnings between £12,570 and £50,270, and 2% on any earnings above £50,270. There is no NI on earnings below £12,570.
You repay 9% of your income above the threshold for your plan. Plan 1: above £26,900. Plan 2: above £29,385. Plan 5: above £25,000. Repayments are deducted automatically through PAYE and do not affect your income tax or NI calculations.
