Frequently Asked Questions
How UK Income Tax Works
Income tax in the UK is progressive — you pay different rates on different portions of your income, not a single flat rate on everything. For 2025/26, the bands are:
Personal Allowance (£0 – £12,570): You pay 0% tax on this portion. Everyone gets this tax-free amount unless they earn over £100,000.
Basic rate (£12,571 – £50,270): You pay 20% on income in this band. So if you earn £30,000, you pay 20% on £17,430 (the amount above your Personal Allowance) = £3,486 in tax.
Higher rate (£50,271 – £125,140): You pay 40% on income in this band. If you earn £60,000, you pay 20% on £37,700 plus 40% on £9,730 = £11,432.
Additional rate (£125,141+): You pay 45% on everything above this threshold.
Worked Example: £35,000 Salary
On a £35,000 salary with no student loan or pension:
Income tax: 20% × (£35,000 − £12,570) = 20% × £22,430 = £4,486
National Insurance: 8% × (£35,000 − £12,570) = 8% × £22,430 = £1,794
Total deductions: £6,280. Take home: £28,720 (£2,393/month).
The £100,000 Tax Trap
One of the most important things to understand about UK tax is what happens between £100,000 and £125,140. Your Personal Allowance is reduced by £1 for every £2 you earn above £100,000. This means you effectively pay 60% tax on income in this range — 40% income tax plus the loss of your tax-free allowance. Someone earning £125,140 has zero Personal Allowance. This is why pension contributions are especially valuable for people in this band — contributing to a pension reduces your taxable income and can restore your Personal Allowance.
National Insurance Explained
National Insurance is a separate deduction from income tax. For employees in 2025/26, you pay 8% on earnings between £12,570 and £50,270, and 2% on anything above £50,270. Unlike income tax, there's no additional rate — the rate actually drops for higher earners. NI contributions count towards your State Pension entitlement.
Student Loan Repayments
Student loan repayments are 9% of everything you earn above your plan's threshold (6% for postgraduate loans). They're not a tax — they're a repayment — but they do reduce your take home pay. If your income drops below the threshold, repayments stop automatically. The thresholds for 2025/26 are: Plan 1 (£26,065), Plan 2 (£28,470), Plan 4 (£32,745), Plan 5 (£25,000), Postgraduate (£21,000).
