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The 60% tax trap: Between £100,000 and £125,140, your personal allowance is withdrawn at £1 for every £2 earned. Combined with the 40% tax rate, this creates an effective marginal rate of 60% on earnings in that band. Pension contributions can help avoid this.

Frequently Asked Questions
On a £30,000 salary in 2026/27, you pay £3,486 in income tax and approximately £2,044 in National Insurance, leaving a monthly take-home of around £2,018. Your effective tax rate is 11.6%.
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Between £100,000 and £125,140, your personal allowance is withdrawn at £1 for every £2 earned over £100,000. Since you're also paying 40% income tax, the effective marginal rate on that band is 60%. Making pension contributions can bring your income below £100,000 and avoid this trap entirely.
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 £24,990. Plan 2: above £27,295. Plan 5: above £25,000. Repayments are deducted automatically through PAYE and do not affect your income tax or NI calculations.
