Income Tax in the UK is not a flat percentage on your whole salary — it is a banded (marginal) system where each slice of income above your Personal Allowance is taxed at a progressively higher rate. Understanding this is essential for financial planning, interpreting payslips, and avoiding common misconceptions about pay rises.
For 2026/27 in England, Wales and Northern Ireland, the bands are: Personal Allowance of £12,570 (taxed at 0%); Basic rate of 20% on income between £12,571 and £50,270; Higher rate of 40% on income between £50,271 and £125,140; and Additional rate of 45% on income above £125,140. The Personal Allowance is tapered and fully withdrawn for incomes above £125,140, creating a marginal rate of 60% on earnings between £100,000 and £125,140 — but this drill focuses on standard cases without the taper for clarity.
This drill generates random salaries and asks you to calculate the total Income Tax by working through each band. An expandable reference table lists all bands for quick consultation, and after you answer you can see a full worked solution showing the taxable amount and tax in every band.
The key insight is that only the income falling within each band is taxed at that band's rate. If you earn £55,000, only £4,730 (£55,000 − £50,270) is taxed at 40%. The rest is taxed at 0% and 20% as normal. A pay rise from £49,000 to £55,000 therefore costs you 40p in Income Tax per extra pound — not 40p on everything.
Scotland has a separate six-band Income Tax system (Starter, Basic, Intermediate, Higher, Advanced, Top) that diverges significantly from the rest of the UK above £31,092, where Scotland's 42% Higher rate kicks in compared to England's 40% at £50,270.
National Insurance is calculated separately and is not included in these drills — see the National Insurance practice for that.
Personal Allowance £0–£12,570 (0%), Basic rate £12,571–£50,270 (20%), Higher rate £50,271–£125,140 (40%), Additional rate above £125,140 (45%). These apply in England, Wales and Northern Ireland.
No — only the income above £50,270 is taxed at 40%. The portion below remains taxed at 0% and 20%. Tax bands are marginal, applied to slices of income.
Yes — Scotland has six bands: Starter (19%), Basic (20%), Intermediate (21%), Higher (42%), Advanced (45%) and Top (48%). Scottish taxpayers pay these rates on non-savings, non-dividend income.
£12,570, frozen since 2021/22 and frozen until at least 2027/28. It tapers to zero for incomes above £100,000 (£1 of PA lost per £2 of income above £100,000).
PAYE (Pay As You Earn) deducts Income Tax and National Insurance from each payslip throughout the year, spreading the liability. Your tax code tells your employer how much tax-free income to allow before deducting tax.
For incomes between £100,000 and £125,140, the Personal Allowance is tapered away at £1 per £2 of income. This means you pay 40% Income Tax plus lose 20p of basic-rate allowance per £1 — creating an effective 60% marginal rate on that slice of income.
No — these drills calculate Income Tax only. Use the National Insurance practice to practise Class 1 employee NI contributions separately.
Personal Allowance: £12,570 @ 0% = £0. Basic rate band: £37,430 (£50,000 − £12,570) @ 20% = £7,486. Total Income Tax = £7,486.
For every £2 of income above £100,000, the Personal Allowance is reduced by £1. At £125,140 the allowance is fully gone, and all income below that point is subject to 40% tax — hence the 60% effective marginal rate.
Broadly yes, but with separate allowances. The Personal Savings Allowance (£500 for basic-rate, £0 for higher-rate) and Dividend Allowance (£500) cover small amounts. Above the allowances, savings interest is taxed at your marginal rate; dividends at 8.75%, 33.75% or 39.35%.
