Most people can receive a Personal Allowance of £12,570 before paying Income Tax. Income above that allowance is taxable and is charged in slices: each band taxes only the part of your taxable income that falls inside it, which is why moving into a higher band never reduces your take-home pay.
In England, Wales and Northern Ireland the basic rate of 20% applies to the first £37,700 of taxable income. The 40% higher rate applies to taxable income from £37,701 to £125,140 — with a full allowance, the 40% tax threshold is reached at around £50,270 of income. The additional rate of 45% applies above £125,140 of taxable income.
Scotland sets its own rates and bands on earnings, with six bands from 19% to 48%. The Personal Allowance itself is a UK-wide figure, so a Scottish taxpayer receives the same allowance but pays Scottish rates on taxable income.
- Personal Allowance = £12,570, reduced by £1 for every £2 of adjusted net income above £100,000.
- Taxable income = income − the Personal Allowance actually available.
- Income Tax = the sum of each band rate applied to the income falling in that band.
